Each tab consists of a Primitive widget surrounded by tab decorations including an optional pixmap. Any non-Primitive widget children of the Folder are placed in the center area. The widgets contained in the tabs can be assigned a non-Primitive widget to display/manage when the tab widget is selected. .SS Class Information Folder inherits from XmManager, Constraint, Composite and Core. Its class pointer is xmlFolderWidgetClass. Its class name is XmLFolder. .SS New Resources .nf .ft B Name Class Type Default Access .ft P XmNactiveTab XmCActiveTab int -1 G XmNautoSelect XmCAutoSelect Boolean True CSG XmNblankBackground XmCBlankBackground Pixel dynamic CSG XmNblankBackgroundPixmap XmCBlankBackgroundPixmap Pixmap dynamic CSG XmNcornerDimension XmCCornerDimension Dimension 2 CSG XmNcornerStyle XmCCornerStyle unsigned char XmCORNER_ARC CSG XmNdebugLevel XmCDebugLevel int 0 CSG XmNfontList XmCFontList XmFontList dynamic CSG XmNhighlightThickness XmCHighlightThickness Dimension 2 CSG XmNinactiveBackground XmCInactiveBackground Pixel dynamic CSG XmNinactiveForeground XmCInactiveForeground Pixel dynamic CSG XmNmarginHeight XmCMarginHeight Dimension 0 CSG XmNmarginWidth XmCMarginWidth Dimension 0 CSG XmNpixmapMargin XmCPixmapMargin Dimension 2 CSG XmNresizePolicy XmCFolderResizePolicy XmRFolderResizePolicy XmRESIZE_STATIC CSG XmNrotateWhenLeftRight XmCRotateWhenLeftRight Boolean True CSG XmNspacing XmCSpacing Dimension 0 CSG XmNtabBarHeight XmCTabBarHeight Dimension dynamic G XmNtabCount XmCTabCount int 0 G XmNtabPlacement XmCTabPlacement unsigned char XmFOLDER_TOP CSG XmNtabsPerRow XmCTabsPerRow int 0 CSG XmNtabTranslations XmCTranslations XtTranslations [focus translations] CG XmNtabWidgetList XmCReadOnly WidgetList dynamic G .fi .IP XmNactiveTab The position of the currently active tab. The first tab on the left has a position of 0. If no tab is active, this value equals -1. .IP XmNautoSelect If True (the default), the Folder will activate its first tab when it is realized. No callback is generated by this action. If False, no initial tab will be activated. .IP XmNblankBackground The color of the area between tabs, around tabs, and between tabs and the edge of the Folder. .IP XmNblankBackgroundPixmap The pixmap to display as a background (tiled) in the blank background area. See XmNblankBackground. .IP XmNcornerDimension If XmNcornerStyle is XmCORNER_LINE, this value is used to determine the length of the lines that clip the corners of the tabs. The greater this value is, the longer the corner lines will be. If XmNcornerStyle is XmCORNER_ARC, this value is used to determine the sizes of the arcs in the corners of the tabs. If XmNcornerStyle is XmCORNER_NONE, this resource has no effect. .IP XmNcornerStyle Defines the type of corners on the individual tabs. Possible values: .nf XmCORNER_NONE /* no corners */ XmCORNER_LINE /* corners are beveled */ XmCORNER_ARC /* corners are round */ .fi .IP XmNdebugLevel If set to a value greater than 0, debugging messages will be printed to stderr. When set to 0 (the default) only error messages will be generated. .IP XmNfontList The default font list for tabs created with the XmLFolderAddTab() functions. Changing this value does not affect existing widgets. If this value is NULL, a font list is obtained from the nearest parent that is a subclass of BulletinBoard, MenuShell, or VendorShell. .IP XmNhighlightThickness The thickness of the highlight drawn around the Primitive widget contained in the active tab. When a Primitive widget is added to the Folder, its highlightThickness is set to 0. The Folder is responsible for drawing the highlight in the active tab. This is necessary because if the Primitive widget were allowed to draw the highlight, it would erase the highlight with an incorrect color. .IP XmNinactiveBackground The background color of inactive tabs. This value is initially set to the background color of the Folder widget. .IP XmNinactiveForeground The foreground color of inactive tabs. This value is initially set to the foreground color of the Folder widget. .IP XmNmarginHeight If tab placement is on the top or bottom, this value is the margin between tab widgets and the top of tabs, and between tab widgets and the bottom of tabs. If tab placement is on the left or right, this value is the margin between tab widgets and the left of tabs, and between tab widgets and the right of tabs. .IP XmNmarginWidth If tab placement is on the top or bottom, this value is the margin between tab widgets and the left of tabs, and between tab widgets and the right of tabs. If tab placement is on the left or right, this value is the margin between tab widgets and the top of tabs and between tab widgets and bottoms of tabs. .IP XmNpixmapMargin The margin between the tab widget and any pixmap to its left. .IP XmNresizePolicy This policy determines when the Folder should perform a request for a new size from its parent. A policy of XmRESIZE_STATIC (the default) will cause the Folder to initially request a size which includes the preferred size of its children and then reject any subsequent resize requests from its non-tab widget children. A policy of XmRESIZE_DYNAMIC will cause the Folder to resize itself to include the preferred size of any of its children whenever its children change size. A policy of XmRESIZE_NONE will cause the Folder to never generate a resize request and also will cause it not to perform geometry management on its non-tab widget children. Possible values: .nf XmRESIZE_NONE /* no resize requests and no placement or geometry management of non-tab children */ XmRESIZE_STATIC /* initially layout to include preferred size of children */ XmRESIZE_DYNAMIC /* dynamically resize as children request new size */ .fi .IP XmNrotateWhenLeftRight If True, XmDrawnButton based tabs (including tabs created with the XmLFolderAddTab() functions) will display their text vertically instead of horizontally if they are placed on the left or right of the Folder. This occurs when the Folder's XmNtabPlacement resource is XmFOLDER_LEFT or XmFOLDER_RIGHT. Tabs on the left would have their text drawn up and tabs on the right would have their text drawn down. If False, tabs are left oriented horizontally regardless of their placement. .IP XmNspacing The amount of space between tabs. .IP XmNtabBarHeight The height, in pixels, of the tab bar. If tab placement is on the left or right, this value is the width of the tab bar. This value may not be set and is only valid after the Folder has been managed and has performed its layout. .IP XmNtabCount The number of tabs displayed. .IP XmNtabPlacement Where to place the tabs. Possible values: .nf XmFOLDER_TOP /* top left to right */ XmFOLDER_BOTTOM /* bottom left to right */ XmFOLDER_LEFT /* left top to bottom */ XmFOLDER_RIGHT /* right top to bottom */ .fi .IP XmNtabsPerRow If set to 0 (the default), the Folder will place tabs in a single row one after another during layout. If non-zero, this value specifies the number of rows of tabs to appear in the Folder and the Folder will pad each row to the width of the Folder by proportionally sizing the tabs based on their contents and the width of the row. .IP XmNtabTranslations The translation table used to augment the translations of Primitive widgets added to the Folder. The Folder overrides the FocusIn and FocusOut translations of its Primitive widget children allowing it to draw and erase tab highlights. .IP XmNtabWidgetList The list of widgets contained inside the tabs. These widgets are subclasses of XmPrimitive. .SS Constraint Resources Folder defines the following constraint resources. .nf .ft B Name Class Type Default Access .ft P XmNtabFreePixmaps XmCTabFreePixmap Boolean False CSG XmNtabInactivePixmap XmCTabInactivePixmap Pixmap XmUNSPECIFIED_PIXMAP CSG XmNtabManagedName XmCTabManagedName String NULL CSG XmNtabManagedWidget XmCTabManagedWidget Widget NULL CSG XmNtabPixmap XmCTabPixmap Pixmap XmUNSPECIFIED_PIXMAP CSG .fi .IP XmNtabFreePixmaps If True, the Folder will call XFreePixmap on the XmNtabPixmap and XmNtabInactivePixmap pixmaps when this widget is destroyed. This value is set to True for tabs created by the XmLFolderAddBitmapTab() functions. .IP XmNtabInactivePixmap The pixmap to appear in the left of the tab when the tab is inactive. .IP XmNtabManagedName By setting a managed name on a tab widget and setting the same managed name on a Manager widget, you specify that the tab manages the Manager widget. You can also specify that a tab manages a specific Manager widget by setting the managed name on the tab widget to the name (XtName) of the Manager widget. If a tab widget has a managed name, the XmNtabManagedWidget resource of the tab widget is ignored. .IP XmNtabManagedWidget Specifies a widget to be managed when this widget is activated. When this widget is deactivated, its managed widget will be unmanaged. This resource allows Manager widgets contained in the center of the Folder to be attached to tabs, so when a user selects a tab its attached Manager widget will be displayed on the screen. .IP XmNtabPixmap The pixmap to appear in the left of the tab when the tab is active. .SS Callback Resources Folder defines the following callback resources. .nf .ft B Callback Reason .ft P XmNactivateCallback XmCR_ACTIVATE .fi .SS Callback Structure Each callback function is passed a pointer to the structure shown below. .nf typedef struct { int reason; /* callback reason */ XEvent *event; /* event callback or NULL */ int pos; /* position of tab to act */ int allowActivate; /* allow/disallow act (1/0) */ } XmLFolderCallbackStruct; .fi pos will be set to the position of the tab (with 0 as the first tab on the left) to activate for XmNactivateCallback callbacks. If allowActivate is set to 0 by the callback function, the tab will not be activated and the attempt to activate the given tab will be rejected. .SS Inherited Resources Folder inherits the resources shown below. .nf .ft B Resource From Resource From .ft P XmNaccelerators Core XmNinitialResourcePersist Core XmNancestorSensitive Core XmNinsertPosition Composite XmNbackground Core XmNmappedWhenManaged Core XmNbackgroundPixmap Core XmNnavagationType Manager XmNborderColor Core XmNnumChildren Composite XmNborderPixmap Core XmNscreen Core XmNborderWidth Core XmNsensitive Core XmNbottomShadowColor Manager XmNshadowThicknses Manager XmNbottomShadowPixmap Manager XmNstringDirection Manager XmNchildren Composite XmNtopShadowColor Manager XmNcolormap Core XmNtopShadowPixmap Manager XmNdepth Core XmNtranslations Core XmNdestroyCallback Core XmNtraversalOn Manager XmNforeground Manager XmNunitType Manager XmNheight Core XmNuserData Manager XmNhelpCallback Manager XmNwidth Core XmNhighlightColor Manager XmNx Core XmNhighlightPixmap Manager XmNy Core .fi .SS Folder Translations Folder defines the translations shown below. .nf .ft B Event Action .ft P BSelect Press XmLFolderActivate() .fi .SS Folder Primitive Translations Folder overrides the translations shown below for all of its Primitive widget children. .nf .ft B Event Action .ft P FocusIn PrimitiveFocusIn() XmLFolderPrimFocusIn() FocusOut PrimtiveFocusOut() XmLFolderPrimFocusOut() .fi .SS Action Routines Folder defines the actions shown below. .IP XmLFolderActivate() Activates the tab at the location of the event passed to the action routine. .IP XmLFolderPrimFocusIn() Draws a highlight around the given widget. .IP XmLFolderPrimFocusOut() Erases the highlight around the given widget. .SH "SEE ALSO" XmLCreateFolder(3X) XmLFolderAddBitmapTab(3X) XmLFolderAddBitmapTabForm(3X) XmLFolderAddTab(3X) XmLFolderAddTabForm(3X) XmLFolderSetActiveTab(3X) nedit-5.6.orig/Microline/man/XmLFolderAddBitmapTab.3x0000644000175000017500000000653110077552126021125 0ustar paulpaul.\" ***** BEGIN LICENSE BLOCK ***** .\" Version: MPL 1.1/GPL 2.0/LGPL 2.1 .\" .\" The contents of this file are subject to the Mozilla Public License Version .\" 1.1 (the "License"); you may not use this file except in compliance with .\" the License.

There are two basic cell types, defined by the nature of the cell content: STRING (XmString format), and PIXMAP (pixmap images). STRING cells may allow editing. Cells and regions within the Grid may be formatted with borders and shadowing. Rows and columns may be fixed on the top, bottom, left and right to remain in view while scrolling horizontally or vertically. There may be heading and footer rows at the top and bottom, and heading and footer columns at the left and right, in addition to the content rows and columns in the center of the Grid. While headings and footers must be fixed, content rows may scroll or may also be fixed on the top, bottom, left and right. .SS Class Information Grid inherits from XmManager, Constraint, Composite and Core. Its class pointer is xmlGridWidgetClass. Its class name is XmLGrid. .SS New Resources The Grid resources defined below affect its overall behavior, layout and appearance. Definitions of resources affecting rows, columns and cells follow the Grid resource definitions. .nf .ft B Name Class Type Default Access .ft P XmNallowColumnHide XmCAllowColumnHide Boolean False CSG XmNallowColumnResize XmCAllowColumnResize Boolean False CSG XmNallowDragSelected XmCAllowDragSelected Boolean False CSG XmNallowDrop XmCAllowDrop Boolean False CSG XmNallowRowHide XmCAllowRowHide Boolean False CSG XmNallowRowResize XmCAllowRowResize Boolean False CSG XmNautoSelect XmCAutoSelect Boolean True CSG XmNblankBackground XmCBlankBackground Pixel Dynamic CSG XmNbottomFixedCount XmCBottomFixedCount int 0 CSG XmNbottomFixedMargin XmCBottomFixedMargin Dimension 0 CSG XmNcolumns XmCColumns int 0 CSG XmNdebugLevel XmCDebugLevel int 0 CSG XmNeditTranslations XmCTranslations XtTranslations Dynamic CSG XmNfontList XmCFontList XmFontList Dynamic CSG XmNfooterColumns XmCFooterColumns int 0 CSG XmNfooterRows XmCFooterRows int 0 CSG XmNglobalPixmapHeight XmCGlobalPixmapHeight Dimension 0 CSG XmNglobalPixmapWidth XmCGlobalPixmapWidth Dimension 0 CSG XmNheadingColumns XmCHeadingColumns int 0 CSG XmNheadingRows XmCHeadingRows int 0 CSG XmNhiddenColumns XmCHiddenColumns int 0 G XmNhiddenRows XmCHiddenRows int 0 G XmNhighlightRowMode XmCHighlightRowMode Boolean False CSG XmNhighlightThickness XmCHighlightThickness Dimension 2 CSG XmNhorizontalScrollBar XmCHorizontalScrollBar Widget Dynamic G XmNhorizontalSizePolicy XmCHorizontalSizePolicy unsigned char XmCONSTANT CSG XmNhsbDisplayPolicy XmCHsbDisplayPolicy unsigned char XmAS_NEEDED CSG XmNimmediateDraw XmCImmediateDraw Boolean False CSG XmNlayoutFrozen XmCLayoutFrozen Boolean False CSG XmNleftFixedCount XmCLeftFixedCount int 0 CSG XmNleftFixedMargin XmCLeftFixedMargin Dimension 0 CSG XmNrightFixedCount XmCRightFixedCount int 0 CSG XmNrightFixedMargin XmCRightFixedMargin Dimension 0 CSG XmNrows XmCRows int 0 CSG XmNscrollBarMargin XmCScrollBarMargin Dimension 2 CSG XmNscrollColumn XmCScrollColumn int Dynamic CSG XmNscrollRow XmCScrollRow int Dynamic CSG XmNselectBackground XmCSelectBackground Pixel Dynamic CSG XmNselectForeground XmCSelectForeground Pixel Dynamic CSG XmNselectionPolicy XmCGridSelectionPolicy unsigned char XmSELECT_BROWSE_ROW CSG XmNshadowRegions XmCShadowRegions int 511 CSG XmNshadowType XmCShadowType unsigned char XmSHADOW_IN CSG XmNsimpleHeadings XmCSimpleHeadings String NULL CSG XmNsimpleWidths XmCSimpleWidths String NULL CSG XmNtextWidget XmCTextWidget Widget Dynamic G XmNtopFixedCount XmCTopFixedCount int 0 CSG XmNtopFixedMargin XmCTopFixedMargin Dimension 0 CSG XmNtraverseTranslations XmCTranslations XtTranslations Dynamic CSG XmNuseAverageFontWidth XmCUseAverageFontWidth Boolean True CSG XmNverticalScrollBar XmCVerticalScrollBar Widget 0 G XmNverticalSizePolicy XmCVerticalSizePolicy unsigned char XmCONSTANT CSG XmNvisibleColumns XmCVisibleColumns int 0 CSG XmNvisibleRows XmCVisibleRows int 0 CSG XmNvsbDisplayPolicy XmCVsbDisplayPolicy unsigned char XmAS_NEEDED CSG .fi .IP XmNallowColumnHide This resource only has effect when XmNallowColumnResize is True. If the user is able to resize columns, this resource controls whether a user can hide a column by resizing it to a zero width. If True, a user may size columns to a zero width (hiding them) and if False (the default), a user will not be able to resize a column to a zero width. .IP XmNallowColumnResize If True, the user may resize a column by dragging the right edge of a cell in a heading row. When the user resizes a column, the column's XmNcolumnSizePolicy is set to XmCONSTANT and the column's XmNcolumnWidth is set to the pixel width chosen by the user. If the Grid contains no heading rows, this resource has no effect. If False, interactive column resizing is disabled. .IP XmNallowDragSelected If True, the user may interactively drag cell contents (strings) to a drop site. If False, dragging is disabled. .IP XmNallowDrop If True, the user is allow to drop cell contents (strings) into the Grid. If False, the Grid will not register itself as a drop site. .IP XmNallowRowHide This resource only has effect when XmNallowRowResize is True. If the user is able to resize rows, this resource controls whether a user can hide a row by resizing it to a zero height. If True, a user may size rows to a zero height (hiding them) and if False (the default), a user will not be able to resize a row to a zero height. .IP XmNallowRowResize If True, the user may resize a row by dragging the bottom edge of a cell in a heading column. When the user resizes a row, the row's XmNrowSizePolicy is set to XmCONSTANT and the row's XmNrowHeight is set to the pixel height chosen by the user. If the Grid contains no heading columns, this resource has no effect. If False, interactive row resizing is disabled. .IP XmNautoSelect If set to True (the default) and the Grid's XmNselectionPolicy is XmSELECT_BROWSE_ROW, the Grid will select its first row when it is realized. No callback is generated by this action. If False, no initial row will be selected. .IP XmNblankBackground If a Grid has a horizontal scrollbar which is scrolled completely to the right or a vertical scrollbar which is scrolled to the bottom, an empty area can exist after the last set of scrolling cells. The color of this empty region is set by the XmNblankBackground resource. It will only be visible when the Grid is scrolled fully to the right or bottom. This value is initially set to the background color of the Grid widget. .IP XmNbottomFixedCount The number of fixed rows at the bottom of the Grid including footer rows. Since footer rows must be fixed, this value may not be set smaller than the number of footer rows. If this value is greater than the total number of rows, then as additional rows are added they will be fixed until this value is reached. .IP XmNbottomFixedMargin The height, in pixels, of the margin between the bottom fixed rows and any rows above them. .IP XmNcolumns The number of content columns. Setting this value will add content columns to the Grid if the value set is greater than the current number of content columns. Likewise, setting this value to a number less than the current number of content columns will cause content columns to be deleted. The Grid updates this resource to reflect the current number of content columns every time a content column is added or removed. To get the total number of columns in the Grid (heading, content and footer) add this value to the number of heading and footer columns. .IP XmNdebugLevel If set to a value greater than 0, debugging messages will be printed to stderr. When set to 0 (the default) only error messages will be reported. .IP XmNeditTranslations The translations merged into the Text widget child of the Grid when the Grid goes from traverse mode into edit mode. .IP XmNfontList The default font list for new cells. Changing this resource does not affect existing cells. If this value is NULL, a font list is obtained from the nearest parent that is a subclass of BulletinBoard, MenuShell, or VendorShell. .IP XmNfooterColumns The number of footer columns. Setting this value will add footer columns to the Grid if the value set is greater than the current number of footer columns. Likewise, setting this value to a number less than the current number of footer columns will cause footer columns to be deleted. The Grid updates this resource to reflect the current number of footer columns every time a footer column is added or removed. .IP XmNfooterRows The number of footer rows. Setting this value will add footer rows to the Grid if the value set is greater than the current number of footer rows. Likewise, setting this value to a number less than the current number of footer rows will cause footer rows to be deleted. The Grid updates this resource to reflect the current number of footer rows every time a footer row is added or removed. .IP XmNglobalPixmapHeight If non-zero, this value specifies the height of every pixmap contained in the cells of the Grid. You should set this resource only if all cell pixmaps have equal size. If you set this resource, you should also set XmNglobalPixmapWidth to the width of the pixmaps. Setting this value will increase performance when setting cell pixmaps since if this value is not set, the Grid will need to perform a query to determine the dimensions of any pixmap set. You should leave this value at 0 (the default) if you have pixmaps of varying size in the Grid. .IP XmNglobalPixmapWidth This resource should be used with XmNglobalPixmapHeight. See XmNglobalPixmapHeight for details. .IP XmNheadingColumns The number of heading columns. Setting this value will add heading columns to the Grid if the value set is greater than the current number of heading columns. Likewise, setting this value to a number less than the current number of heading columns will cause heading columns to be deleted. The Grid updates this resource to reflect the current number of heading columns every time a heading column is added or removed. .IP XmNheadingRows The number of heading rows. Setting this value will add heading rows to the Grid if the value set is greater than the current number of heading rows. Likewise, setting this value to a number less than the current number of heading rows will cause heading rows to be deleted. The Grid updates this resource to reflect the current number of heading rows every time a heading row is added or removed. .IP XmNhiddenColumns The total number of hidden columns. The Grid updates this resource every time a column is hidden or unhidden. Hidden columns are columns with a width of 0. .IP XmNhiddenRows The total number of hidden rows. The Grid updates this resource every time a row is hidden or unhidden. Hidden rows are rows with a height of 0. .IP XmNhighlightRowMode If True, a highlight is drawn around the entire row containing the cell which has focus instead of just around the current cell which has focus. If False (the default), when a cell has focus, the highlight will be drawn only around that cell. .IP XmNhighlightThickness The thickness of the highlight rectangle drawn in cells with focus. This value must be 0 or 2. .IP XmNhorizontalScrollBar The widget ID of the Grid's horizontal ScrollBar. .IP XmNhorizontalSizePolicy Determines how the Grid sizes itself horizontally. Possible values: .nf XmVARIABLE /* Grid always requests full width */ XmCONSTANT /* user or parent sets Grid width and scrollbar is displayed if required */ .fi If this value is XmVARIABLE, the Grid determines the amount of horizontal space required to display the entire Grid and requests this space from its parent. When the width of the Grid changes, it will request more or less space causing it to shrink or expand as its parent widget allows. It will appear truncated, without a horizontal ScrollBar, if not enough space is given by the parent. If this value is XmCONSTANT the user or the parent widget must define the Grid’s width and a horizontal ScrollBar will appear if needed. .IP XmNhsbDisplayPolicy When XmNhorizontalSizePolicy is XmCONSTANT, this resource controls whether to display the horizontal scroll bar if all rows fit in the viewing area. Possible values: .nf XmSTATIC /* scrollbar always displays */ XmAS_NEEDED /* scrolbar only displayed when scrolling is possible */ .fi .IP XmNimmediateDraw If False (the default), the Grid queues up and compresses drawing events. For example, if you change a cell's background and later change the cell's foreground, the Grid will only draw the cell once to reflect the changes. This drawing compression includes sending expose events to the X Server. If you do not want the Grid to queue and compress drawing events, you should set this value to True. You would want to set this resource to True in the case where you had a very slow connection to an X Server (over a serial line for instance). If set to True and the line to the X Server is slow, more drawing will be performed but the the drawing will show up faster. .IP XmNlayoutFrozen If True, the Grid's layout is frozen and the Grid will not recompute its layout until this resource is set to False. When this resource is set back to False, the layout will be recomputed and the entire Grid will redraw. When rows or columns are added to or deleted from the Grid, or if row heights, column widths or margins are changed, the Grid must recompute its layout by determining which cells to display on the screen. If a number of changes to the Grid layout are going to take place, then by setting this resource to True before executing the first change and setting it to False after the last change is requested, the Grid will not recompute its layout after each change. Setting this value will not affect what is displayed on the screen as it is only used to increase performance. If only a single layout change is requested, such as when adding or deleting a single range of rows or columns, this resource should not be used in an attempt to increase performance as the change may not require a redraw of the Grid. This resource should also not be used around code which does not cause the Grid to recompute its layout, such as changing cell or border colors, as that would decrease performance. .IP XmNleftFixedCount The number of fixed columns at the left of the Grid including heading columns. Since heading columns must be fixed, this value may not be set smaller than the number of heading columns. If this value is greater than the total number of columns, then as additional columns are added they will be fixed until this value is reached. .IP XmNleftFixedMargin The width, in pixels, of the margin between the left fixed columns and any columns to their right. .IP XmNrightFixedCount The number of fixed columns at the right of the Grid including footer columns. Since footer columns must be fixed, this value may not be set smaller than the number of footer columns. If this value is greater than the total number of columns, then as additional columns are added they will be fixed until this value is reached. .IP XmNrightFixedMargin The width, in pixels, of the margin between the right fixed columns and any columns to their left. .IP XmNrows The number of content rows. Setting this value will add content rows to the Grid if the value set is greater than the current number of content rows. Likewise, setting this value to a number less than the current number of content rows will cause content rows to be deleted. The Grid updates this resource to reflect the current number of content rows every time a content row is added or removed. To get the total number of rows in the Grid (heading, content and footer) add this value to the number of heading and footer rows. .IP XmNscrollBarMargin The margin, in pixels, between the ScrollBars and the displayed cells. .IP XmNscrollColumn The left-most scrolling content column currently displayed. This value may be set to change the current scroll position. If setting this value causes the scroll position to change, the Grid's scroll callbacks will be called. If this value is set greater than the last possible scrolling column, the Grid will scroll to the last possible scrolling column. If this value is set less than the first possible scrolling column, the Grid will scroll to the first possible scrolling column. .IP XmNscrollRow The top scrolling content row currently displayed. This value may be set to change the current scroll position. If setting this value causes the scroll position to change, the Grid's scroll callbacks will be called. If this value is set greater than the last possible scrolling row, the Grid will scroll to the last possible scrolling row. If this value is set less than the first possible scrolling row, the Grid will scroll to the first possible scrolling row. .IP XmNselectBackground The background color of cells, rows or columns which are currently selected. This value is initially set to the foreground color of the Grid widget. .IP XmNselectForeground The foreground color of cells, rows or columns which are currently selected. This value is initially set to the background color of the Grid widget. .IP XmNselectionPolicy Determines the types of selections allowed in the Grid. In SELECT_NONE mode, user selections have no effect by default and cell select callbacks are called each time a user selects a cell. The application may set selections of rows/columns or cells. In SELECT_SINGLE_ROW mode, one or zero content rows may be selected. In SELECT_BROWSE_ROW mode, one content row must be selected at all times. In SELECT_MULTIPLE_ROW, multiple content rows may be selected. In any of the SELECT_..._ROW modes, when cells in heading or footer rows are selected by a user, the Grid will call its cell select callbacks. Therefore, the application must be sure to check the type of selection made in its select callback(s). In SELECT_CELL mode, arbitrary regions of cells in content rows and content columns may be selected. A user may select cells in heading rows to select columns and cells in heading columns to select rows. Possible values: .nf XmSELECT_NONE /* no selections */ XmSELECT_SINGLE_ROW /* 0 or 1 row selection */ XmSELECT_BROWSE_ROW /* 1 row selection */ XmSELECT_MULTIPLE_ROW /* multiple row selection */ XmSELECT_CELL /* multiple row, column, cell selections */ .fi .IP XmNshadowRegions Determines which regions are drawn with shadows. There are 9 regions in the Grid numbered as follows: .nf 1 2 4 8 16 32 64 128 256 .fi Where 1, 2 and 4 combine to make the top fixed rows. 1, 8 and 64 combine into the left fixed columns, 16 is the scrolling region, etc. The value should be set to the summation of the region’s numbers which should be drawn with a shadow. For example, if this value is set to 428 (64 + 128 + 256) the Grid will draw a shadow box around each region in the bottom row. Regions not included are drawn without shadows. .IP XmNshadowType The type of shadows to draw around the regions of the Grid. Possible values: .nf XmSHADOW_ETCHED_IN /* etched in appearance */ XmSHADOW_ETCHED_OUT /* etched out appearance */ XmSHADOW_IN /* inset appearance */ XmSHADOW_OUT /* outset appearance */ .fi .IP XmNsimpleHeadings This resource may be used to set cell strings in the first heading row in a Grid with a simple C string. The value passed should be a null-terminated C string containing headings separated by the pipe symbol. A heading row must exist at the time of this call which contains the number of cells which will be affected or the Grid will generate a warning. The following example sets the headings of a Grid to "First", "Second" and "Third": .nf XtVaSetValues(grid, XmNsimpleHeadings, "First|Second|Third", NULL); .fi The Grid makes a copy of the string passed to it for this resource in a SetValues call. The Grid will return a pointer to this internal copy of the string if GetValues is called for this resource and the pointer returned should not be freed by an application. .IP XmNsimpleWidths This resource may be used to set the widths of columns in a Grid. The value passed should be a null-terminated C string containing numbers specifying widths and a letter 'p' or 'c' following the number to indicate whether the width is in pixels or characters. A space should be used after each letter to separate columns. The columns affected by the call must exist at the time a value is set, or the Grid will generate a warning. The following example sets the width of the first column to 10 characters wide and the second column to 20 pixels wide: .nf XtVaSetValues(grid, XmNsimpleWidths, "10c 20p", NULL); .fi The Grid makes a copy of the string passed to it for this resource in a SetValues call. The Grid will return a pointer to this internal copy of the string if GetValues is called for this resource and the pointer returned should not be freed by an application. .IP XmNtextWidget The widget ID of the Grid's Text widget. .IP XmNtopFixedCount The number of fixed rows at the top of the Grid including heading rows. Since heading rows must be fixed, this value may not be set smaller than the number of heading rows. If this value is greater than the total number of rows, then as additional rows are added they will be fixed until this value is reached. .IP XmNtopFixedMargin The height, in pixels, of the margin between the top fixed rows and any rows below them. .IP XmNtraverseTranslations The translations merged into the Text widget child of the Grid when the Grid goes from edit mode into traverse mode. .IP XmNuseAverageFontWidth Cells in the Grid which contain text calculate their preferred width based on the font list character width of the font list assigned to the cell. The Grid calculates the font list character width when font lists are assigned to cells. If the value of this resource is True, the font list character width will be calculated by averaging all of the glyph widths in the font list. If this value is False, the font list character width will equal the the maximum glyph width in the font list. Changing this resource only affects font lists assigned after this value is changed, it does not affect the current layout of the Grid. Also, this resource only affects cells containing proportional fonts since a fixed width font's average glyph width will equal its maximum glyph width. .IP XmNverticalScrollBar The widget ID of the Grid's vertical ScrollBar. .IP XmNverticalSizePolicy Determines how the Grid sizes itself vertically. Possible values: .nf XmVARIABLE /* Grid always requests full height */ XmCONSTANT /* user or parent sets Grid height and scrollbar is displayed if needed */ .fi If this value is XmVARIABLE, the Grid determines the amount of vertical space required to display the entire Grid and requests this space from its parent. When the height of the Grid changes, it will request more or less space causing it to shrink or expand as its parent widget allows. It will appear truncated, without a vertical ScrollBar, if not enough space is given by the parent. If this value is XmCONSTANT the user or the parent widget must define the Grids height and a vertical ScrollBar will appear if needed. .IP XmNvisibleColumns Setting this resource causes the Grid to request a width from its parent equal to the value set multiplied by the width of a standard 8 character wide cell. The actual width in pixels requested is: .nf shadowThickness * 2 + value * (4 + 8 * defaultFontWidth + defaultLeftMargin + defaultRightMargin) .fi The width requested is not determined using any existing column values. For example, if you have 3 columns which are each 20 characters wide and you set XmNvisibleColumns to 3, the width requested will not fit the 3 columns of 20 characters, it will fit 3 columns of 8 characters (without Grid borders). The width requested does depend on the default font in the Grid, however, to determine the width of a standard 8 character wide cell. If you want the Grid to request a width equal to the width of the existing columns, see the XmNhorizontalSizePolicy resource's XmVARIABLE setting. .IP XmNvisibleRows Setting this resource causes the Grid to request a height from its parent equal to the value set multiplied by the height of a default 1 character height cell. The actual height in pixels requested is: .nf shadowThickness * 2 + value * (4 + defaultFontHeight + defaultTopMargin + defaultBottomMargin) .fi The height requested is not determined using any existing row values. For example, if you have 10 rows which are each 3 characters high and you set XmNvisibleRows to 10, the height requested will not fit the 10 existing rows, it will fit fit 10 rows of 1 character height (without Grid borders). The height requested does depend on the default font in the Grid, however, to determine the height of a standard cell. If you want the Grid to request a height equal to the height of the existing rows, see the XmNverticalSizePolicy resource's XmVARIABLE setting. .IP XmNvsbDisplayPolicy When XmNverticalSizePolicy is XmCONSTANT, this resource controls whether to display the vertical scroll bar if all rows fit in the viewing area. Possible values: .nf XmSTATIC /* scrollbar always displays */ XmAS_NEEDED /* scrolbar only displayed when scrolling is possible */ .fi .SS Row/Column/Cell Resources Grid defines the resources in the table below affecting rows, columns and cells. A SetValues call can set values for a single column using XmNcolumn or for a range of columns using XmNcolumnRangeStart and XmNcolumnRangeEnd. Row values can be set using XmNrow or XmNrowRangeStart and XmNrowRangeEnd. Cell values can be set for a single cell using XmNcolumn and XmNrow, or a range of cells using a variety of combinations of row and column specifications. A GetValues call can retrieve values for a column using XmNcolumnPtr, a row using XmNrowPtr, and a cell using both XmNcolumnPtr and XmNrowPtr. .nf .ft B Name Class Type Default Access .ft P XmNcellAlignment XmCCellAlignment unsigned char XmALIGNMENT_CENTER SG XmNcellBackground XmCCellBackground Pixel Dynamic SG XmNcellBottomBorderColor XmCCellBottomBorderColor Pixel Dynamic SG XmNcellBottomBorderType XmCBottomBorderType unsigned char XmBORDER_LINE SG XmNcellColumnSpan XmCCellColumnSpan int 0 SG XmNcellDefaults XmCCellDefaults Boolean False S XmNcellEditable XmCCellEditable Boolean False SG XmNcellFontList XmCCellFontList XmFontList Dynamic SG XmNcellForeground XmCCellForeground Pixel Dynamic SG XmNcellLeftBorderColor XmCCellLeftBorderColor Pixel Dynamic SG XmNcellLeftBorderType XmCCellLeftBorderType unsigned char XmBORDER_LINE SG XmNcellMarginBottom XmCCellMarginBottom Dimension 0 SG XmNcellMarginLeft XmCCellMarginLeft Dimension 0 SG XmNcellMarginRight XmCCellMarginRight Dimension 0 SG XmNcellMarginTop XmCCellMarginTop Dimension 0 SG XmNcellPixmap XmCCellPixmap Pixmap XmUNSPECIFIED_PIXMAP SG XmNcellPixmapMask XmCCellPixmapMask Pixmap XmUNSPECIFIED_PIXMAP SG XmNcellRightBorderColor XmCCellRightBorderColor Pixel Dynamic SG XmNcellRightBorderType XmCCellRightBorderType unsigned char XmBORDER_LINE SG XmNcellRowSpan XmCCellRowSpan int 0 SG XmNcellString XmCXmString XmString NULL SG XmNcellTopBorderColor XmCCellTopBorderColor Pixel Dynamic SG XmNcellTopBorderType XmCCellTopBorderType unsigned char XmBORDER_LINE SG XmNcellType XmCCellType unsigned char XmSTRING_CELL SG XmNcellUserData XmCUserData XtPointer 0 SG XmNcolumn XmCGridColumn int -1 S XmNcolumnPtr (none) XtPointer 0 G XmNcolumnRangeEnd XmCColumnRangeEnd int -1 S XmNcolumnRangeStart XmCColumnRangeStart int -1 S XmNcolumnSizePolicy XmCColumnSizePolicy unsigned char XmVARIABLE SG XmNcolumnStep XmCColumnStep int 1 S XmNcolumnType XmCColumnType unsigned char XmCONTENT S XmNcolumnWidth XmCColumnWidth Dimension 8 SG XmNcolumnUserData XmCUserData XtPointer 0 SG XmNrow XmCGridRow int -1 S XmNrowHeight XmCRowHeight Dimension 1 SG XmNrowPtr (none) XtPointer 0 G XmNrowRangeEnd XmCRowRangeEnd int -1 S XmNrowRangeStart XmCRowRangeStart int -1 S XmNrowSizePolicy XmCRowSizePolicy unsigned char XmVARIABLE SG XmNrowStep XmCRowStep int 1 S XmNrowType XmCRowType unsigned char XmCONTENT S XmNrowUserData XmCUserData XtPointer 0 SG .fi .IP XmNcellAlignment Determines the alignment of the XmString or Pixmap contained in the cell. Possible values: .nf XmALIGNMENT_LEFT /* left, centered vertically */ XmALIGNMENT_CENTER /* centered horizontally and vertically */ XmALIGNMENT_RIGHT /* right, centered vertically */ XmALIGNMENT_TOP_LEFT /* top left */ XmALIGNMENT_TOP /* top, centered horizontally */ XmALIGNMENT_TOP_RIGHT /* top right */ XmALIGNMENT_BOTTOM_LEFT /* bottom left */ XmALIGNMENT_BOTTOM /* bottom, centered horizontally */ XmALIGNMENT_BOTTOM_RIGHT /* bottom right */ .fi If a cell Pixmap does not have a width or height set, the cell's alignment will be top left regardless of the value of this resource since any other alignment could not be calculated. .IP XmNcellBackground The cell's background color. .IP XmNcellBottomBorderColor The color of the cell's bottom border. If the cell's bottom border type is XmBORDER_NONE, no bottom border will be drawn and this resource has no effect. The default value of this resource is the bottom shadow color of the Grid. .IP XmNcellBottomBorderType Determines the type of border to draw at the bottom of the cell. Possible values: .nf XmBORDER_NONE /* no border */ XmBORDER_DASH /* dashed line */ XmBORDER_LINE /* line border */ .fi .IP XmNcellColumnSpan The number of columns to the right that are spanned by this cell. You may combine this with a row span to span both rows and columns. When a cell spans into adjacent cells, those spanned cells are not displayed; instead, the contents of the spanning cell are displayed in the spanned area. This effectively makes the spanning cell larger while not changing the cell's row or column size. If cell spans overlap, the visual behavior of the spanned cells will become undefined. If rows or columns are added or deleted inside a spanned area, the visual behavior of the spanned cells will become undefined. If rows or columns are moved or reordered in a way which does not preserve existing cell spans, the visual behavior of the spanned cells will become undefined. The width of a column span in pixels cannnot exceed the maximum value of the type Dimension. Setting a column span on a cell sets its preferred cell width to 4 pixels. All cells in a span must exist at the time the span is set. .IP XmNcellDefaults Setting this value to True in a SetValues call indicates that the call is setting the default cell values. The default cell values can be assigned on a per-column basis by setting this resource to True and setting a column (using XmNcolumn) or a range of columns in the SetValues call. For example, to set the default editibility for cells in column 0 to editable, you could: .nf XtVaSetValues(grid, XmNcellDefaults, True, XmNcolumn, 0, XmNcellEditable, True, NULL); .fi This specifies that any cell created (cells are created by adding rows or columns) in column 0 will be editable by default. If you do not specify a column in a SetValues call where XmNcellDefaults is True, the default cell values in the call will be set for all columns. Inotherwords, it will set the defaults for any new cell created. This value is always reset to False after a SetValues call completes. .IP XmNcellEditable Allow (True) or disallow (False) a user either by typing, using a cut/paste or drag/drop operation, to edit the cell. This may only be set to True for cells with a XmNcellType of XmSTRING_CELL. .IP XmNcellFontList The font list used for the cell's text. By default, the value of this resource is set to the Grid's XmNfontList. Changing this value may cause the row or column containing the cell to resize if the row's XmNrowSizePolicy or the column's XmNcolumnSizePolicy is XmVARIABLE. .IP XmNcellForeground The cell's foreground color. .IP XmNcellLeftBorderColor The color of the cell's left border. If the cell's left border type is XmBORDER_NONE, no left border will be drawn and this resource has no effect. The default value of this resource is the top shadow color of the Grid. .IP XmNcellLeftBorderType Determines the type of border to draw at the left of the cell. Possible values: .nf XmBORDER_NONE /* no border */ XmBORDER_DASH /* dashed line */ XmBORDER_LINE /* line border */ .fi .IP XmNcellMarginBottom The height, in pixels, of the margin between the bottom of the cell and the cell's contents. .IP XmNcellMarginLeft The width, in pixels, of the margin between the left of the cell and the cell's contents. .IP XmNcellMarginRight The width, in pixels, of the margin between the right of the cell and the cell's contents. .IP XmNcellMarginTop The height, in pixels, of the margin between the top of the cell and the cell's contents. .IP XmNcellPixmap The Pixmap to draw in the cell if the cell's type is XmPIXMAP_CELL. As in other widgets, the Grid does not make a copy of the Pixmap. Therefore, the Pixmap should not be freed until it is no longer required to be displayed by the Grid. Changing this value may cause the row or column containing the cell to resize if the row's XmNrowSizePolicy or the column's XmNcolumnSizePolicy is XmVARIABLE. This value may be XmUNSPECIFIED_PIXMAP. .IP XmNcellPixmapMask The pixmap mask to use when drawing a cell if the cell's type is XmPIXMAP_CELL. This value must be either XmUNSPECIFIED_PIXMAP (the default) or a Pixmap of depth 1. If set to a Pixmap of depth 1, the Pixmap specified will be used as a mask for drawing the cell's contents. As in other widgets, the Grid does not make a copy of the Pixmap passed. Therefore, the Pixmap should not be freed until it is no longer required to be used by the Grid. .IP XmNcellRightBorderColor The color of the cell's right border. If the cell's right border type is XmBORDER_NONE, no right border will be drawn and this resource has no effect. The default value of this resource is the bottom shadow color of the Grid. .IP XmNcellRightBorderType Determines the type of border to draw at the right of the cell. Possible values: .nf XmBORDER_NONE /* no border */ XmBORDER_DASH /* dashed line */ XmBORDER_LINE /* line border */ .fi .IP XmNcellRowSpan The number of rows below that are spanned by this cell. You may combine this with a column span to span both rows and columns. When a cell spans into adjacent cells, those spanned cells are not displayed; instead, the contents of the spanning cell are displayed in the spanned area. This effectively makes the spanning cell larger while not changing the cell's row or column size. If cell spans overlap, the visual behavior of the spanned cells will become undefined. If rows or columns are added or deleted inside a spanned area, the visual behavior of the spanned cells will become undefined. If rows or columns are moved or reordered in a way which does not preserve existing cell spans, the visual behavior of the spanned cells will become undefined. The height of a row span in pixels cannnot exceed the maximum value of the type Dimension. Setting a row span on a cell sets its preferred cell height to 4 pixels. All cells in a span must exist at the time the span is set. .IP XmNcellString The compound string to draw in the cell if the cell's type is XmSTRING_CELL. As in other widgets, the Grid makes a copy of the string and so the string may be freed after it is used to set this value. Retrieving this value will return a copy of the cell's string, therefore the retrieved string should be freed when it will no longer be used. This value may be NULL. .IP XmNcellTopBorderColor The color of the cell's top border. If the cell's top border type is XmBORDER_NONE, no top border will be drawn and this resource has no effect. The default value of this resource is the top shadow color of the Grid. .IP XmNcellTopBorderType Determines the type of border to draw at the top of the cell. Possible values: .nf XmBORDER_NONE /* no border */ XmBORDER_DASH /* dashed line */ XmBORDER_LINE /* line border */ .fi .IP XmNcellType The type of the cell. Possible values: .nf XmSTRING_CELL /* cell displaying XmString */ XmPIXMAP_CELL /* cell displaying a Pixmap */ .fi Changing this value may cause the row or column containing the cell to resize if the row's XmNrowSizePolicy or the column's XmNcolumnSizePolicy is XmVARIABLE. Changing a cell's type from XmSTRING_CELL to XmPIXMAP_CELL will free the XmNcellString currently contained in the cell and will set the XmNcellString to NULL. Changing from XmPIXMAP_CELL to XmSTRING_CELL will cause the cell's XmNcellPixmap to be set to XmUNSPECIFIED_PIXMAP. .IP XmNcellUserData A pointer value unused by the Grid. This resource allows you to attach a pointer to any cell in the Grid. .IP XmNcolumn Defines which column(s) or cell(s) a SetValues call will affect. A value of -1 (the default) means all columns. This value is always reset to -1 after the SetValues call completes. The value of 0 defines the first column of a column type. This resource may not be used in a GetValues call. .IP XmNcolumnPtr Defines which column, or column a cell is contained in, a GetValues call should retrieve values for. This value is a pointer to a column which should be obtained using XmLGridGetColumn(). This resource may not be used in a SetValues call. .IP XmNcolumnRangeEnd Defines the last column or column of cells in a range which a SetValues call will affect. This resource may not be used in a GetValues call. This resource must be used with the XmNcolumnRangeStart resource. .IP XmNcolumnRangeStart Defines the first column or column of cells in a range which a SetValues call will affect. This resource may not be used in a GetValues call. This resource must be used with the XmNcolumnRangeEnd resource. .IP XmNcolumnSizePolicy Defines how the column width is determined. Possible values: .nf XmCONSTANT /* column size is fixed */ XmVARIABLE /* column may resize when cell size changes */ .fi If XmVARIABLE, the column will size itself to the maximum preferred width of the column's cells. For cells containing text, this usually equals the cell's average or maximum font list glyph width multiplied by the XmNcolumnWidth (plus space for borders, etc). If XmCONSTANT, the XmNcolumnWidth value is assumed to be in pixels and the column width will equal that value. .IP XmNcolumnStep Defines the column increment when setting values of multiple columns or cells in a SetValues call. For example, a column step of 2 will skip every other column. This value is 1 by default and will reset to 1 after a SetValues call completes. .IP XmNcolumnType Defines which type of columns or cells a SetValues call will affect. This resource may not be used in a GetValues call. Possible values: .nf XmALL_TYPES /* all column types - heading, content and footer */ XmCONTENT /* columns containing the Grid's contents */ XmHEADING /* heading columns on the far left */ XmFOOTER /* footer columns on the far right */ .fi This resource is used along with XmNcolumn or XmNcolumnRangeStart and XmNcolumnRangeEnd and determines which type of column the column or column range specifies. By default, this value is set to XmCONTENT. This value is always reset to XmCONTENT after a SetValues call completes. .IP XmNcolumnUserData A pointer value unused by the Grid. This resource allows you to attach a pointer to any column in the Grid. .IP XmNcolumnWidth If XmNcolumnSizePolicy is XmVARIABLE, the value of this resource represents the column width in characters and if a font list in any cell in the column is changed, the column will resize if required. The pixel width of a column is determined by the maximum preferred width of the column's cells. Cells containing text usually determine their preferred width by multiplying the cell's average or maximum font list glyph width by the column's XmNcolumnWidth. Pixmap cells ignore this resource since their preferred width is the width of their pixmap. If XmNcolumnSizePolicy is XmCONSTANT, the value of this resource represents the column width in pixels. .IP XmNrow Defines which row(s) or cell(s) a SetValues call will affect. A value of -1 (the default) means all rows. The value of 0 defines the first row of a row type. This value is always reset to -1 after a SetValues call completes. This resource may not be used in a GetValues call. .IP XmNrowHeight If XmNrowSizePolicy is XmVARIABLE, the value of this resource represents the row height in characters and if a font list in any cell in this row is changed, the row will resize if required. The pixel height of a row is determined by the maximum preferred height of the row's cells. Cells containing text usually determine their preferred height by taking their maximum font list character height and multiplying it by the row's XmNrowHeight. Pixmap cells ignore this resource since their preferred height is the height of their pixmap. If XmNrowSizePolicy is XmCONSTANT, the value of this resource represents the row height in pixels. .IP XmNrowPtr Defines which row, or row a cell is contained in, a GetValues call should retrieve values for. This value is a pointer to a row which should be obtained using XmLGridGetRow(). This resource may not be used in a SetValues call. .IP XmNrowRangeEnd Defines the last row or row of cells in a range which a SetValues call will affect. This resource may not be used in a GetValues call. This resource must be used with the XmNrowRangeStart resource. .IP XmNrowRangeStart Defines the first row or row of cells in a range which a SetValues call will affect. This resource may not be used in a GetValues call. This resource must be used with the XmNrowRangeEnd resource. .IP XmNrowSizePolicy Defines how the row height is determined. Possible values: .nf XmCONSTANT /* row size is fixed */ XmVARIABLE /* row may resize when cell size changes */ .fi If XmVARIABLE, the row will size itself to the maximum preferred height of the row's cells. For cells containing text, this usually equals the cell's maximum font list glyph height multiplied by the XmNrowHeight (plus space for borders, etc). If XmCONSTANT, the XmNrowHeight value is assumed to be in pixels and the row height will equal that value. .IP XmNrowStep Defines the row increment when setting values of multiple rows or cells in a SetValues call. For example, a row step of 2 will skip every other row. This value is 1 by default and will reset to 1 when a SetValue call completes. .IP XmNrowType Defines which type of rows or cells a SetValues call will affect. This resource may not be used in a GetValues call.

Along with a Progress meter, this widget may optionally display text with percentage completion and elapsed and estimated time to completion. .SS Class Information Progress inherits from XmPrimitive and Core. Its class pointer is xmlProgressWidgetClass. Its class name is XmLProgress. .SS New Resources .nf .ft B Name Class Type Default Access .ft P XmNcompleteValue XmCCompleteValue int 100 CSG XmNfontList XmCFontList XmFontList fixed CSG XmNmeterStyle XmCMeterStyle unsigned char XmMETER_BAR CSG XmNnumBoxes XmCNumBoxes int 10 CSG XmNshowPercentage XmCShowPercentage Boolean True CSG XmNshowTime XmCShowTime Boolean False CSG XmNvalue XmCValue int 0 CSG .fi .IP XmNcompleteValue Defines the maximum value of the XmNvalue resource. When the XmNvalue resource reaches this number, the Progress bar will show 100% complete. This value is used to determine the percentage to complete and to estimate time to completion. .IP XmNfontList The font list used for drawing the percentage complete and estimated time. .IP XmNmeterStyle The style of the meter to draw. Possible values: .nf XmMETER_BAR /* standard bar meter */ XmMETER_BOXES /* shadowed boxes meter */ .fi Only the XmMETER_BAR style can display the percentage complete indicator and optional and estimated time to completion. .IP XmNnumBoxes When XmNmeterStyle is XmMETER_BOXES, this resource defines the number of boxes to display in the meter. .IP XmNshowPercentage If set to True, text will be shown centered in the widget displaying the current percentage complete. The percentage complete is calculated by dividing the XmNvalue by the XmNcompleteValue. .IP XmNshowTime If set to True, the widget will display the elapsed time in the left of the widget and the estimated time remaining on the right. The estimated time remaining is calculated using the XmNvalue, the XmNcompleteValue and the start time. The start time is the last time the XmNvalue was set to 0. No estimated time is shown when XmNvalue is 0 or when it is equal to the XmNcompleteValue. If set to False, only a percentage complete indicator will be shown. .IP XmNvalue A value from 0 to the XmNcompleteValue which defines how much progress has taken place. When this value is set to 0, the current time is stored as the start time for calculating estimated time to completion. .SS Inherited Resources Progress inherits the resources shown below .nf .ft B Resource From Resource From .ft P XmNaccelerators Core XmNhighlightPixmap Primitive XmNancestorSensitive Core XmNhighlightThickness Primitive XmNbackground Core XmNinitialResourcesPersistent Core XmNbackgroundPixmap Core XmNmappedWhenManaged Core XmNborderColor Core XmNnavagationType Primitive XmNborderPixmap Core XmNscreen Core XmNborderWidth Core XmNsensitive Core XmNbottomShadowColor Primitive XmNshadowThickness Primitive XmNbottomShadowPixmap Primitive XmNtopShadowColor Primitive XmNcolormap Core XmNtopShadowPixmap Primitive XmNdepth Core XmNtranslations Core XmNdestroyCallback Core XmNtraversalOn Primitive XmNforeground Primitive XmNunitType Primitive XmNheight Core XmNuserData Primitive XmNhelpCallback Primitive XmNwidth Core XmNhighlightColor Primitive XmNx Core XmNhighlightOnEnter Primitive XmNy Core .fi .SH "SEE ALSO" XmLCreateProgress(3X) nedit-5.6.orig/Microline/man/XmLRectIntersect.3x0000644000175000017500000000556310077552127020300 0ustar paulpaul.\" ***** BEGIN LICENSE BLOCK ***** .\" Version: MPL 1.1/GPL 2.0/LGPL 2.1 .\" .\" The contents of this file are subject to the Mozilla Public License Version .\" 1.1 (the "License"); you may not use this file except in compliance with .\" the License.

Each row in the Tree has a position and level which is used to determine its relationship to other rows in the Tree. Rows may be expanded or collapsed by clicking on an expand/collapse graphic or by activating a row with the keyboard. The Tree inherits all the abilities of the Grid widget, allowing it to contain multiple columns and rows of varying types, heading and fixed rows and columns, interactive row and column resizing, cell borders, etc. .SS Class Information Tree inherits from XmLGrid, XmManager, Constraint, Composite and Core. Its class pointer is xmlTreeWidgetClass. Its class name is XmLTree. .SS New Resources The Tree resources defined below affect its overall layout and appearance. Definitions of resources affecting rows, columns and cells follow the Tree resource definitions. .nf .ft B Name Class Type Default Access .ft P XmNconnectingLineColor XmCConnectingLineColor Pixel Dynamic CSG XmNlevelSpacing XmCLevelSpacing Dimension 11 CSG XmNplusMinusColor XmCPlusMinusColor Pixel Dynamic CSG .fi .IP XmNconnectingLineColor The color of the line which is drawn connecting parents, children and siblings in the first column of the Tree. This values defaults to the foreground color of the Tree. .IP XmNlevelSpacing The indent in pixels for each level in the Tree. .IP XmNplusMinusColor The color of the plus and minus expand/collapse graphics drawn next to parent nodes which may be expanded. This value defaults to the foreground color of the Tree. .SS Row/Column/Cell Resources Tree defines the resources in the table below affecting rows. In addition to these row resources, the Tree inherits all the row, column and cell resources which exist in the Grid. .nf .ft B Name Class Type Default Access .ft P XmNrowExpands XmCRowExpands Boolean False SG XmNrowIsExpanded XmCRowIsExpanded Boolean True SG XmNrowLevel XmCRowLevel int 0 SG .fi .IP XmNrowExpands True if the row may expand (it is a parent) and False otherwise. .IP XmNrowIsExpanded True if the row is currently expanded and False otherwise. If this resource is set to False, the Tree will hide all children of this row. Children of this row are determined to be all rows which are of a level greater than this row's until we find the next row which is of this row's level or less (a sibling or parent of this row).

This Grid is set to not allow selection.\ \n\n\ The Grid Three sample allows editing and is set to allow \ selection of mulitple rows, columns and/or cells. Note that an \ edit may be accepted by pressing Return or by moving to a new \ location and may be rejected with the Escape key. You may \ edit an existing cell's contents using the F2 or Insert key. \ This Grid also supports interactive row and column resizing. \ Drag and drop is permitted by selecting an area to be dragged \ and performing a drag-and-drop operation (using mouse button 2) \ to copy the selected area to another location.\ \n\n\ The Grid includes a number of advanced features such as:\ \n\ - string (editable or non-editable XmString format) or pixmap cells\n\ - keyboard traversal using arrow keys, page keys, etc.\n\ - add, delete, reorder, move and hiding of rows/columns\n\ - heading, content and footer rows/columns\n\ - top, bottom, left and/or right fixed rows/columns\n\ - rows/column intelligently size to cell fonts/images\n\ - user-adjustable row/column sizes\n\ - cells may span rows/columns\n\ - full control of cell borders and colors\n\ - 9 cell alignment options (top-left, center, etc)\n\ - uses reference-counted cell attributes to save memory\n\ - SetValues on ranges of cells/rows/columns\n\ - callbacks for select, activate, draw, edit, focus, etc.\n\ - cut, paste, drag and drop of cell contents\n\ - ASCII file import and export\ \n\n\ The Grid widget is ideal for replacing single-column Motif \ scrolled lists with multi-column lists. Its also perfect for creating \ high-performance tables. Tables may be created where the data \ displayed is not kept in the Grid itself but retrieved from a \ database when it needs to be displayed. This direct database \ access can save memory and time loading/storing the table. \ Click-sorting may be added to the table to allow a user to \ sort rows by clicking on a column heading.\ \n\n\ Cell attributes in the Grid are reference counted. If a number \ of cells in the Grid have similar attributes (color, fonts, etc) \ they may all contain a pointer to the same attributes structure \ instead of creating an attributes structure for each individual \ cell. This reference counting is transparent to a programmer \ creating a Grid.\ \n\n\ Cells may have borders set on the top, bottom, left and right and \ have a number of color/alignment options. Keyboard traversal is \ provided using the standard Motif key mappings of Page Up, \ Page Down, Home, etc. Selection modes are provided to allow \ selection of a single row (browse mode or single mode), multiple \ rows and arbitrary regions of rows, columns and cells. \ Functions are provided to easily import data to and from text \ files.\ \n\n\ The 3.0 release has added resources allowing you to specify cell \ defaults on a per-column basis (e.g. all cells in column 2 will be \ editable). Also, the Grid's layout has improved for sizing policies \ where scrollbars appear as needed. The Grid now will use all the \ space it can for data instead of not using the space where the \ scrollbars would appear. \ \n\n\ A number of resources have been added in the 3.0 release to support \ better integration with interface builders. You can now add and \ delete rows and also set column widths and simple headings through \ resources.\ \n\n\ Internally the Grid is a Manager widget which contains two \ ScrollBar children and one Text widget child.";

This includes selection policies \ of single row, multiple row, etc. as well as full control over colors, \ fonts, alignment, borders, etc. on a per-cell basis. The Tree \ also supports all the other features of the Grid, including heading, \ content and footer rows and columns, various cell types etc.\ \n\n\ An application may add rows to the Tree and let the Tree handle \ the expansion and collapse of rows, or for large trees, \ an application may handle the expansion and collapse of rows \ by adding (creating) and deleting rows dynamically as needed.\ \n\n\ Resources exist to set the indent level, various colors of the \ Tree, etc. As stated earlier, the Tree also contains all the \ resources available in the Grid.\ \n\n\ This widget is new in the 3.0 release.";

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

This is fixed by giving all documents a gutter of the same size. 2006-09-30 16:09 tringali * source/nedit.c (1.93): SF 1564907: guard against bogus XKEYSYMDB 2006-09-27 11:51 michaelsmith * makefiles/buildvms.com (1.2), source/macro.c (1.105), source/window.c (1.190): BUG #1395689 Patches to permit nedit to be compiled under OpenVMS VMS compilation script and patches contributed by zinser@zinser.no-ip.info 2006-08-22 13:23 yooden * util/getfiles.c (1.36): Using Lesstif, util/getfiles.c compiled only with a warning about a missing #include . 2006-08-17 17:33 ajbj * source/search.c (1.81): Fix for bug 1541650 where non-regex replace-in-selection didn't work. 2006-08-15 21:16 yooden * Microline/XmL/Folder.c (1.7), Microline/XmL/Tree.c (1.3), source/menu.c (1.137), source/preferences.c (1.144): Removes some compiler warnings and minor bugs on VMS. It compiles and runs on Linux, I have no way to check it on VMS. 2006-08-15 18:55 ajbj * source/: preferences.h (1.54), search.c (1.80): Made function prototypes match their definitions (added "const"). This corrects broken builds. 2006-08-15 18:36 ajbj * source/preferences.c (1.143): Adds a line to the nedit.rc file header commentary: ! (User settings in X "application defaults" format) which allows copies to be recognised as X app default files for syntax highlighting using the language detection regex for X Resources. 2006-08-13 21:47 yooden * source/: highlightData.c (1.75), preferences.c (1.142), rangeset.c (1.15), regularExp.c (1.30), search.c (1.79): This fixes several small issues: - Some bugs in various language modes pointed out by Volker Kuhlmann. - Some compiler warning (function footprint) caused from my latest changes. - Some compiler warnings (variable initialisation) from elsewhere. - One stuck return. 2006-08-13 18:41 yooden * ReleaseNotes (1.41), doc/help.etx (1.99), source/file.c (1.99), source/nedit.h (1.67), source/preferences.c (1.141), source/preferences.h (1.53), source/window.c (1.189): Fix for SF#1027788 On opening a symlink, NEdit as yet creates a new document. This behaviour is now optional: If the new resource nedit.honorSymlinks is set to false, NEdit will try to detect whether the file is already opened with another filename. 2006-08-13 18:02 yooden * ReleaseNotes (1.40), doc/help.etx (1.98), source/nedit.h (1.66), source/preferences.c (1.140), source/preferences.h (1.52), source/regularExp.c (1.29), source/regularExp.h (1.14), source/search.c (1.78), source/search.h (1.27): Fix for SF#1015499 An internal buffer limits the size of replace operation; the result was truncated at 511 characters. This change increases the buffer limit to 5119 characters and prevents data loss by catching an already existing internal error higher up the call chain. A new resource let's the user decide how the error is handled then. 2006-08-12 13:40 yooden * ReleaseNotes (1.39), doc/help.etx (1.97), source/file.c (1.98), source/preferences.c (1.139), source/preferences.h (1.51): Fix for SF#1003241 NEdit converts all open files into an internal Unix-like representation. This mechanism is lacking for files which contains both LF and CRLF. This patch adds the resource 'nedit.forceOSConversion' which, if set to False, prohibits all internal conversion. DOS and Mac files are no longer conveniently editable, but the stranger file types are editable at all. 2006-08-09 08:50 edg * source/highlightData.c (1.74): Proper fix for part of SF bug #1536451, correcting my previous attempt. 2006-08-08 18:06 tringali * util/system.h (1.18): Updates for newer Solaris (sparc + x86) boxes. 2006-08-08 10:59 edg * ReleaseNotes (1.38), source/highlightData.c (1.73), util/managedList.c (1.15): Fixes for SF bug #1536451: highlighting pattern capacity overflow. Limits on the number of patterns per set were not properly checked, or not checked at all. 2006-08-07 15:41 edg * ReleaseNotes (1.37), source/regularExp.c (1.28): Fix for SF bug #1536002: highlighting pattern compilation crash. An invalid size was used in a malloc call, causing memory corruption. 2006-08-06 18:34 edg * util/getfiles.c (1.35): Workaround for a Lesstif bug that caused a crash in the Save As dialog when a proportional font is used (reported by Alexey Kuznetsov at the discuss list). 2006-05-31 16:39 n8gray * source/macro.c (1.104): Added #include as potential fix for SF #1493662. Also fixed an unused variable warning. 2006-04-21 21:13 ajbj * source/: macro.c (1.103), textBuf.c (1.33), textBuf.h (1.18): From patch 1191453: Avoiding buffer copying in macro search; use the text buffer directly instead. 2006-04-11 06:29 n8gray * source/window.c (1.188): Since I'm on a roll, this is TK's fix for SF bug 1460456: Crash when saving over open file. 2006-04-11 01:14 n8gray * doc/help.etx (1.96), source/help_data.h (1.86), source/help_topic.h (1.75), source/macro.c (1.102), util/getfiles.c (1.34), util/getfiles.h (1.11): Adds two new (long overdue!) builtin functions to the macro language for displaying file-selection dialogs: new_filename_dialog exist_filename_dialog Includes one unbracketed if statement, just as flamebait. :-) 2006-03-17 14:20 edg * ReleaseNotes (1.36), util/getfiles.c (1.33): Fix for SF bug #1451337: current file name does not appear in "save as" dialog box 2006-03-17 10:05 edg * util/misc.c (1.82): Suppressed one more usually bogus clipboard locking warning. 2006-03-17 09:31 edg * ChangeLog (1.43): Long overdue ChangeLog update (cvs2cl.pl -b -r -t --accum --gmt). 2006-02-11 10:37 yooden * ReleaseNotes (1.35), source/macro.c (1.101), util/utils.c (1.25), util/utils.h (1.15): Fix for SF#622291 If a macro file is loaded with load_macro_file() (ie. from another macro) and code segments alternate with function definitions, the code segments were executed in reverse order. This is fixed by adding a stack to store and reverse the plain code segments. 2006-02-10 22:10 ajbj * source/rangeset.c (1.14): Fixed broken "optimisation" - noticed by TK Soh 2006-02-05 18:29 yooden * makefiles/Makefile.solaris (1.11): Fix for SF#860249 Some reports indicate that setting NO_XMIM is the more useful option on Solaris. 2006-02-05 16:31 yooden * util/: utils.c (1.24), utils.h (1.14): This removes some bogus 'extern' declarations from util/utils.[ch]. 2006-02-02 20:24 yooden * source/: menu.c (1.136), preferences.c (1.138), preferences.h (1.50), search.c (1.77): Fix for SF#1406894 I removed the shell setting from TempStringPrefs. While PrefData.shell is touched in translatePrefFormats() (putting in the default shell), there is no need to use the more complicated storage. Also included are some related small changes: - The menu entry 'Select Shell' is renamed to 'Command Shell'. - I removed the arbitray restriction found in MAX_SH_LEN and replaced all references with MAXPATHLEN. 2006-01-14 11:42 yooden * source/file.c (1.97): Reorders the #include directives, as pointed out by Martin Zinser. 2006-01-14 10:26 yooden * source/menu.c (1.135): This moves the "Sort Open Prev. Menu" entry into the "Customize Menus" submenu, as suggested by Dimitar Zhekov on discuss@. 2006-01-02 23:10 yooden * source/menu.c (1.134): Doh. For some reason it worked without #include before. 2006-01-02 22:35 yooden * ReleaseNotes (1.34), doc/help.etx (1.95), source/menu.c (1.133), source/preferences.c (1.137), source/preferences.h (1.49), source/shell.c (1.41): Fix for SF#403738 and SF#880607 This cleans up the shell problems by - bringing the shell setting into NEdit's normal settings, removing it from the X server's setting. - Changing the default shell to the user's login shell, falling back on sh. I also smuggled in a change to ReleaseNotes about SF#557032 I forgot then. 2006-01-02 22:18 yooden * source/file.c (1.96): Removes redundand #ifdefs within eponymous #ifndefs. 2006-01-02 22:07 yooden * source/menu.c (1.132): Cleanup for the recent changes on the history database handling. This pulls together the file check on the existing file on disk. 2005-12-28 22:19 tringali * source/help.c (1.105): Fix incorrect reporting of bad vs. unknown. 2005-12-27 20:55 yooden * doc/help.etx (1.94): This cuts a long paragraph in the help into multiple smaller paragraphs. 2005-12-18 03:46 tksoh * source/menu.c (1.131): Fix premature setting of mtime tracking variable on nedit.history file. 2005-12-17 19:23 yooden * source/: menu.c (1.130), nedit.h (1.65), window.c (1.187): Fix for SF#1381893 As TK pointed out in the original bug report (SF#557032), internal state is not adequate to keep the file history consistent if more than one session is running. Once you accept that external state must be checked you don't need to keep internal state at all. So this patch removes the prevOpenMenuValid flag from WindowInfo and the rest of the code. Validity of the menu is determined using only the directory entry of the history file. 2005-12-14 23:08 yooden * source/menu.c (1.129): Fix for SF#557032, based on TK's fix attached there. NEdit's file history is now read not only once at startup, but also every time a file the history is written and before the menu is refreshed. This catches files written by other instances of NEdit. 2005-12-10 23:21 yooden * source/textDisp.c (1.63): Fix for SF#1368576 The fix for SF#464967 increased the area processed by redisplayLine() by one to let it know that the cursor should be redrawn. This was done by increasing the endIndex given to redisplayLine() by one. Sadly, endIndex is INT_MAX in some cases, which prevented redisplays completely in certain cases. This fix moves the incrementation to a saner place. Neither the bugs fixed with SF#464967 nor any of the examples given in SF#1368576's description are visible. Again, I notice no drawbacks. 2005-12-01 14:31 tringali * Xlt/: BubbleButton.c (1.9), BubbleButtonP.h (1.5), SlideC.c (1.5), SlideCP.h (1.4): Revert out partoffset stuff - it's Motif 2 only. Need to rewrite so it's conditional 2005-11-30 17:52 tringali * source/macro.c (1.100): Avoid crash if cancel accelerator is unset. 2005-11-30 17:48 tringali * Xlt/: BubbleButton.c (1.8), BubbleButtonP.h (1.4), SlideC.c (1.4), SlideCP.h (1.3): Patch from ICS to do proper subclassing - this will make it more immune to binary incompatible changes in OpenMotif. 2005-11-29 20:37 n8gray * source/smartIndent.c (1.38): Fix for bug #1369091. Matlab autoindent init macro should end with a newline. 2005-11-28 22:43 yooden * ReleaseNotes (1.33), source/highlightData.c (1.72): Fix for SF#858874 There was a tiny typo in Ada's syntax highlighting pattern. 2005-11-28 21:51 yooden * util/check_lin_tif.c (1.13): Removes a warning from GCC: warning: ISO C89 forbids mixed declarations and code This is simply done by wrapping blocks around the declarations. 2005-11-28 21:35 yooden * ReleaseNotes (1.32): Adds comment about fix to SF#464967 and SF#1041077 to ReleaseNotes. 2005-11-26 00:17 yooden * source/textDisp.c (1.62): Fix for SF#464967. The area redisplayed from within TextDRedisplayRange() is appended by one character. This is necessary to let the logic in redisplayLine() know that the caret should be redrawn (hasCursor = true) which in turn triggers the redraw by calling drawCursor() later in the function. Both representations of the bug described in the bug report plus two more for multi-line redraws are fixed. I noticed no drawbacks. 2005-11-25 19:58 yooden * util/misc.c (1.81): MaCke sure we get no compile errors.VS: Committing in . 2005-11-20 06:48 n8gray * util/misc.c (1.80): Make sure we get the prototype for select on OS X systems. 2005-11-18 10:40 edg * util/misc.c (1.79): Removed another unnecessary warning: XmClipboardInquireLength() can legally fail when the clipboard is empty. 2005-11-08 22:22 edg * source/: file.c (1.95), nedit.h (1.64), window.c (1.186): Fix for SF bug #1345424: externally changed file status not recognised. The file's uid and gid are now recorded too to detect any changes. 2005-09-23 14:23 edg * util/misc.c (1.78): Partially reverted my previous checkin: the empty clipboard check should not have been removed; only the warning. 2005-09-23 14:18 edg * util/misc.c (1.77): Removed an unnecessary warning: XmClipboardRetrieve can legally fail when the clipboard is empty. 2005-09-23 14:08 tringali * source/nedit.c (1.92): Disable UTF8 stomping where it's not a problem (OM2.2.3+) 2005-08-13 19:29 edg * source/macro.c (1.99), source/textSel.c (1.15), util/misc.c (1.76), util/misc.h (1.28): Added clipboard spinlocks to make clipboard manipulations more robust, especially in the presence of other applications accessing the clipboard. 2005-08-06 04:56 tksoh * source/window.c (1.185): Fixed bug where line number panel didn't adjust to fully display the last line number (10000) when newline was added, with 9999 lines in the tab before addition. 2005-08-06 04:31 tksoh * source/nc.c (1.47): Fixed nc's prompt on -ask. 2005-07-30 18:05 edg * source/server.c (1.33): Presumable fix for SF bug #1078786: "-untabbed" option of nc sometimes ignored. The option now works as intended with (older) window managers that are not _NET_WM compliant. 2005-06-22 07:34 edg * doc/help.etx (1.93), source/help_data.h (1.85), source/help_topic.h (1.74): More documentation updates by Joerg Fischer. 2005-06-20 10:54 edg * doc/help.etx (1.92), doc/nedit.pod (1.9), source/help_data.h (1.84), source/help_topic.h (1.73): More documentation updates by Joerg Fisher. 2005-06-09 16:44 edg * doc/help.etx (1.91), source/help_data.h (1.83), source/help_topic.h (1.72): Typo fixes (Joerg Fischer). 2005-05-30 07:44 edg * doc/help.etx (1.90), source/help_data.h (1.82), source/help_topic.h (1.71): Typo fix (Joerg Fischer). 2005-05-27 16:58 edg * source/regularExp.c (1.27): Fix for SF bug #1204893: regular expressen cuts replaced textparts. A warning is now written to stderr when truncation occurs. (Ideally, all errors and warnings should be signaled via dialogs, but that requires architectural changes). 2005-05-27 16:50 edg * source/shell.c (1.40): Minor fix. 2005-05-27 16:49 edg * README (1.48), Microline/XmL/Folder.h (1.3), Microline/XmL/Grid.h (1.3), Microline/XmL/Progress.h (1.3), Microline/XmL/Tree.h (1.3), Microline/XmL/XmL.c (1.3), Xlt/BubbleButton.c (1.7), Xlt/BubbleButtonP.h (1.3), Xlt/SlideC.c (1.3), Xlt/SlideCP.h (1.2), makefiles/buildvms.com (1.1), source/comnedit.com (1.10), source/file.c (1.94), source/lnknedit.com (1.8), source/menu.c (1.128), source/shell.c (1.39), source/window.c (1.184), util/comutil.com (1.5): VMS porting fixes contributed by Michael Smith. 2005-04-15 14:16 edg * source/shell.c (1.38): Fix for SF bug#1183759: HP compiler uninitialized variable. The variable isn't actually used when it isn't initialized. 2005-03-23 12:34 edg * Microline/Makefile (1.3), Microline/Makefile.in (1.3), Xlt/Makefile (1.1): Fix for SF bug #1066152: Microline Widget Library does not Compile Added a working makefile for the Microline and Xlt subdirectories. 2005-03-06 15:38 tringali * util/motif.c (1.4): Bug 1087192: avoid LessTif 0.93.95b 2005-03-03 14:49 edg * doc/help.etx (1.89), doc/nc.pod (1.7), doc/nedit.pod (1.8), source/help_data.h (1.81), source/help_topic.h (1.70), source/nc.c (1.46), source/nedit.c (1.91): Added -h/-help command line options and clarified warn-on-exit. 2005-02-24 18:23 edg * source/highlightData.c (1.71): Extended C, C++, Yacc, and Lex patterns to recognize strings inside preprocessor lines to avoid erroneous matching of comment pattern on strings. 2005-02-23 03:00 ajbj * source/preferences.c (1.136): Changed default line wrap mode to continuous (SF bug 1124850, rfe 1087257). 2005-02-18 11:10 edg * doc/help.etx (1.88), source/help_data.h (1.80), source/help_topic.h (1.69): Minor clarification in regex help. 2005-02-16 07:18 n8gray * source/menu.c (1.127): Makes unloadTipsAP refresh any existing tear-offs. 2005-02-16 05:09 ajbj * doc/help.etx (1.87), source/help_data.h (1.79), source/help_topic.h (1.68): Added help information on the new macro string escape sequences. 2005-02-16 03:44 ajbj * source/: parse.y (1.28), parse_noyacc.c (1.9): Adds Patch 970487: \xXX and \0ooo style escaped characters to macro strings. Nothing in the help about this (yet). 2005-02-15 09:13 edg * source/menu.c (1.126): Fix for SF bug #1122813: Tab-related crash on posting unload calltips file menu. 2005-02-15 03:44 tringali * util/: motif.c (1.3), motif.h (1.2): Added Motif exception to license 2005-02-15 01:10 n8gray * source/: menu.c (1.125), preferences.c (1.135), tags.c (1.64), tags.h (1.16): Calltips files are now reference-counted. This should address bug #1025123 - Error loading default calltips file. Fixing this uncovered another bug, however, that I haven't been able to fix. I'll file a bug on it later. Also, can somebody look at menu.c, compare unloadTagsAP with unloadTipsAP, and address my comment on the latter? 2005-02-14 23:45 yooden * util/motif.c (1.2): Removes warning. 2005-02-14 22:18 yooden * source/nedit.c (1.90), util/prefFile.c (1.26): This sets the maximum tab width to 150. This prevents some resizing of the tabs, making the UI less jumpy. It is also what most users probably expect from the tabs, since most apps work with tabs of limited size. This also slightly changes some error messages. 2005-02-14 14:40 tringali * util/: motif.c (1.1), motif.h (1.1): Minor cleanup of Motif checker to keep #ifdef's all in one place (part 2) 2005-02-12 12:04 edg * util/misc.c (1.75): Fix for SF bug #1030467: "Enabling Composite Extension in Xorg 6.8 breaks Nedit", presumably also for SF bug #1048304: "Very slow resizing of Nedit window on Xorg 6.8", and possibly also for SF bug #1070918: "new tab -> Segmentation fault", and SF bug #1030192: "X_PolyFillRectange error with X 6.8 and xcompmgr" 2005-02-12 01:53 tringali * source/help.c (1.104), source/nedit.c (1.89), util/Makefile.common (1.9), util/check_lin_tif.c (1.12): Minor cleanup of Motif checker to keep #ifdef's all in one place. 2005-02-11 02:42 ajbj * doc/help.etx (1.86), source/help_data.h (1.78), source/help_topic.h (1.67), source/macro.c (1.98): Integrated patch 1003088 allowing substring to drop the end position argument. It also uses negative positions as measurements from the end of the string. 2005-02-11 01:46 ajbj * doc/help.etx (1.85), source/help_data.h (1.77), source/help_topic.h (1.66), source/macro.c (1.97): Integrated patch 991602, removing limits on the number of buttons in dialogs. 2005-02-10 03:35 ajbj * source/macro.c (1.96): Buffer length fixes to rangeset functions I forgot when changing rangeset.c. 2005-02-06 12:31 yooden * doc/help.etx (1.84): Changes documentation for the replace_range() macro function. This function moves the cursor when it is in the replaced range. In these cases, the cursor has no clear best position, so a documentation is all we can do. 2005-02-02 09:15 edg * source/textDrag.c (1.11): Added dummy initializations to suppress bogus compiler warnings. 2005-02-02 09:08 edg * source/nedit.c (1.88): Minor leak fix. 2005-02-02 09:07 edg * source/macro.c (1.95): Fix for the critical split() macro bug reported by Joerg Fischer: using a zero-width assertion pattern as the split pattern (regex mode) resulted in a seemingly endless loop (ended by a crash). Zero-width assertion patterns now work as expected. Eg: split("abcdef", "(?=c)", "regex") -> "ab", "cdef". 2005-01-31 14:39 edg * ChangeLog (1.42): Regenerated (cvs2cl.pl -b -r -t --accum --gmt). 2005-01-31 14:34 edg * source/: preferences.c (1.134), userCmds.c (1.53), userCmds.h (1.11): Fix for SF bug #1113183: lang. mode seq. change - user menu LM dependency not update. (Patch by Uwe Lehnert) 2005-01-29 01:57 ajbj * source/rangeset.c (1.13): Fix for SF bug 1111849: the calculation of maxpos in rangesets should give the valid text length in the text buffer. It doesn't, since it adds in the size of the buffer's gap! 2005-01-18 20:58 n8gray * source/nedit.c (1.87): Adds bindings for Ctrl-f/g to the help system. 2005-01-06 06:23 ajbj * source/macro.c (1.94): The previous focus window filename fixes did not cope with pathless documents such as the initial Untitled window. This patch does a simple name search before attempting a search using normalized names. 2005-01-06 06:09 ajbj * util/misc.c (1.74): Fix for bug 1096970: the patch fixes focus change problems in RadioButtonChangeState() by saving the widget with focus then restoring focus after the button has been properly set (only required for some buggy Motifs). 2004-12-24 13:05 tksoh * source/window.c (1.183): Fixed a bug where rangesets do not get highlighted (colored) properly when the host document is detached/attached, if syntax highlighting is on. 2004-12-23 22:25 edg * doc/help.etx (1.83), source/file.c (1.93), source/help.c (1.103), source/help_data.h (1.76), source/help_topic.h (1.65), source/highlightData.c (1.70), source/menu.c (1.124), source/preferences.c (1.133), source/preferences.h (1.48), source/search.c (1.76), source/smartIndent.c (1.37), source/tags.c (1.63), source/userCmds.c (1.52), source/window.c (1.182), source/window.h (1.29), source/windowTitle.c (1.15), util/misc.c (1.73), util/misc.h (1.27): Fix for SF bug #1067619: focus on raise. By default, NEdit no longer requests the input focus when a window is raised. This default can be overridden by setting the X-resource "nedit.focusOnRaise" to True. The raise_window() action routine also accepts an optional extra argument: 'focus' or 'nofocus', which can be used to override the focus behaviour determined by the resource. 2004-12-17 11:54 edg * source/: search.c (1.75), search.h (1.26), window.c (1.181): Fix for SF bug #1086664: Repeatable crash closing window. Closing a window while a modal dialog is up, triggered from a find or replace dialog button action routine, is virtually impossible. We can prevent illegal accesses to destroyed windows (which is the reason for the crash), but we cannot avoid that Motif accesses structures that get destroyed in the process. Therefore, it is now no longer possible to close a window via the window manager during the execution of a search dialog button action routine in that window. 2004-12-05 01:23 tksoh * source/file.c (1.92): Fix for SF Bug #1063542: On some systems, such as Solaris 2.6, the "New File" dialog does not appear when trying to open a non-existing file with nc, while the NEdit window is iconized. 2004-12-05 01:15 tksoh * source/menu.c (1.123): Fix for SF Bug #1076412: "Unload Tags File" menu tear-offs not refreshed after unloading tags files. Tear-offs will be closed when all tags files are unloaded. 2004-11-26 18:25 edg * doc/help.etx (1.82), source/help_data.h (1.75), source/help_topic.h (1.64), source/highlight.c (1.51), source/preferences.c (1.132), source/regularExp.c (1.26), source/regularExp.h (1.13), source/search.c (1.74): Fix for SF bug #1067402: Error in syntax highlighting with sub-pattern. For this, the regular expression needed to be extended such that it allows imposing a boundary on the matching (instead of letting matches extend till the terminating \0). This also enabled me to lift a minor limitation of the look-behind matching. Also fixed 5 probably very old bugs in the regex engine that could easily result in crashes (try replacing \y+ with abc in an empty document for an instant crash). 2004-11-26 17:54 edg * util/misc.c (1.72): Minor leak fix. 2004-11-23 14:37 tringali * source/interpret.c (1.43): Remove sprintf call - this won't compile on many platforms. 2004-11-21 16:53 yooden * source/interpret.c (1.42): Makes error message construction a little more robust by replacing sprintf() with snprintf(). There is a constant already in use for this (MAX_ERR_MSG_LEN), so we should use it to prevent mishaps. 2004-11-09 21:58 yooden * doc/setext (1.13), source/calltips.h (1.4), source/file.h (1.15), source/highlight.h (1.14), source/highlightData.h (1.13), source/interpret.h (1.18), source/macro.h (1.8), source/menu.h (1.13), source/nedit.h (1.63), source/parse.h (1.7), source/preferences.h (1.47), source/rbTree.h (1.5), source/regexConvert.h (1.7), source/regularExp.h (1.12), source/search.h (1.25), source/selection.h (1.7), source/server.h (1.7), source/server_common.c (1.6), source/server_common.h (1.3), source/shell.h (1.9), source/shift.h (1.6), source/smartIndent.h (1.8), source/tags.h (1.15), source/text.h (1.23), source/textBuf.h (1.17), source/textDisp.h (1.28), source/textDrag.h (1.5), source/textP.h (1.12), source/textSel.h (1.6), source/undo.h (1.8), source/userCmds.h (1.10), source/window.h (1.28), source/windowTitle.c (1.14), source/windowTitle.h (1.5), util/DialogF.h (1.11), util/clearcase.c (1.6), util/clearcase.h (1.5), util/fileUtils.h (1.12), util/fontsel.h (1.11), util/getfiles.h (1.10), util/managedList.h (1.7), util/misc.h (1.26), util/prefFile.h (1.8), util/printUtils.h (1.9), util/utils.h (1.13), util/vmsParam.h (1.6), util/vmsUtils.h (1.7): A large number of files carried a pointer to the wrong licence (LGPL), probably introduced by a pasting error during the licence clarification. This was changed to point to the GPL. 2004-11-09 19:37 yooden * source/: macro.c (1.93), menu.c (1.122): Two problems with potentially too long pathnames are fixed: 1. The open() action procedure handled the results of ParseFilename wrong: It was only checked for each single component whether it's > MAXPATHLEN, not for the combination. This is fixed now. 2. If the pathname given to focus_window() is > MAXPATHLEN, the function returns with an error now. 2004-11-07 20:03 edg * source/macro.c (1.92): Fix for my "fix" for SF bug #1060749: truncate the string to MAXPATHLEN + other improvements suggested by Tony. 2004-11-05 08:44 edg * source/macro.c (1.91): Fix for SF bug #1060749: focusWindowMS (macro.c) causes crash. 2004-11-02 12:55 edg * source/shell.c (1.37): Enabled the navigation keys (arrows, page-up/down, ...) for shell output dialogs. 2004-10-18 19:27 arnef * source/calltips.c (1.9), source/rangeset.c (1.12), source/tags.c (1.62), source/textDisp.c (1.61), source/window.c (1.180), util/check_lin_tif.c (1.11), util/misc.c (1.71), util/utils.c (1.23): Added missing 'static'. Changed to initial lower case letter on two static functions. 2004-10-18 16:05 yooden * makefiles/Makefile.linux (1.13): Reverts accidental checkin of Linux makefile. 2004-10-18 15:54 yooden * doc/help.etx (1.81), makefiles/Makefile.linux (1.12), source/file.c (1.91), source/macro.c (1.90), source/menu.c (1.121), source/nedit.c (1.86), source/tags.c (1.61), util/fileUtils.c (1.33), util/utils.c (1.22): This fixes two bugs: 1. SF#873188 2. focus_window() didn't work if the pathname had extra slashes. Both items were affected by pathname creation quirks in source/file.c and util/fileUtils.c and there is the straightforward focus_window change in macro.c. Changes in other files are documentation or cleanups. I don't have access to OS/2 or Cygwin systems, so please have a close look on these two. VMS should not be affected. 2004-10-15 18:04 arnef * source/: interpret.c (1.41), interpret.h (1.17), nedit.c (1.85), preferences.c (1.131), preferences.h (1.46), tags.c (1.60), userCmds.c (1.51), userCmds.h (1.9): Added missing void in declarations and definitions (continuation of work done by edg 04/10/14 14:53:25) 2004-10-15 13:57 edg * source/nedit.c (1.84), util/misc.c (1.70): This should fix the problems that we have with drag icons when using non-default visuals (especially on Solaris). All shells that Motif creates beyond our control should now inherit the proper (non-default) visual etc. via the resource database. An exception is made for Lesstif, which seems to be able to deal with non-default visuals on its own (and which doesn't like us to impose visuals). Drag-and-drop operations are now enabled under all circumstances as they should no longer result in crashes (opening the path for patches that rely on d&d). 2004-10-14 21:55 edg * source/server.c (1.32): Added missing initialization (Arne Førlie). 2004-10-14 21:53 edg * source/userCmds.h (1.8): Added missing void in declaration (Arne Førlie) 2004-10-13 17:38 tringali * util/system.h (1.17): Guess compiler for older SGI boxes. 2004-10-08 22:58 yooden * ReleaseNotes (1.31), source/highlightData.c (1.69): Adds a pattern for nested command substitution in the shell pattern set. 2004-10-08 22:26 yooden * ReleaseNotes (1.30), source/shell.c (1.36): The status bar reflects a changed keybinding in the shell command banner. This is brought over from the similar code for macros. 2004-10-08 21:55 yooden * ReleaseNotes (1.29), source/text.c (1.51), source/text.h (1.22), source/window.c (1.179): Fixes SF#906878 (Cursor blinks while typing) by introducing the new function ResetCursorBlink() which can be used to reset the caret blink timer. 2004-10-08 11:35 edg * ChangeLog (1.41): Regenerated (cvs2cl.pl -b -r -t --accum --gmt). 2004-10-08 11:24 edg * source/window.c (1.178): Fix for replace dialog buttons not being updated when switching tabs, possibly resulting in temporarily inconsistent button states. Candidate fix for 5.5.1. 2004-10-07 22:34 yooden * doc/help.etx (1.80), source/file.c (1.90), source/menu.c (1.120), source/nedit.h (1.62), source/preferences.c (1.130), source/preferences.h (1.45), source/search.c (1.73), source/search.h (1.24), source/text.c (1.50), source/text.h (1.21), source/textDisp.c (1.60), source/textDisp.h (1.27), source/textP.h (1.11), source/window.c (1.177), source/window.h (1.27), util/getfiles.c (1.32), util/getfiles.h (1.9), util/prefFile.c (1.25): I was asked to elaborate on this commit. So here goes: This commit is a mistake because the codebase is made worse by it. The code removed is of higher quality than the average commit, is of use to many users of NEdit and would have been the basis for even more improvements in code quality and usability. Ironically, this commit is the result of all the things it claimed to heal: That one developer considers the repository his personal playground and forces his view onto others. While there is no basis for the original complaint, the aggressive tone, stubborn insistence and insulting nature of the comeback makes it clear that this something much different than honest care about the community process. What could have been a minor nuisance was blown out of all proportation and made to a personal vendetta. At the same time, any attempts to get to a closure were not ignored, but actively impeded, any calming voice was shouted down. Despite all this, I figured the commit would put an end to the unpleasant situation and would offer the opportunity to restart. Despite the attempts to prevent this, I'd still rather work on NEdit than defend against personal attacks. So with this commit I take back the added features Hidden Files (SF#502840), Wrap Hairline (SF#701337 variant) and Smart Case Search (SF#685618) committed on 2004-10-01. 2004-10-07 10:27 edg * source/undo.c (1.18): Fix for SF bug #988220: backup file?. The backup file was not removed when a redo operation returned the document to the state where it matches the saved file. Closing the document then left behind the backup file. 2004-10-02 13:31 yooden * source/: menu.c (1.119), textDisp.c (1.59): Fixes a wrong assumption about the hairline code. 2004-10-01 10:13 yooden * doc/help.etx (1.79), source/menu.c (1.118), source/nedit.h (1.61), source/preferences.c (1.129), source/preferences.h (1.44), source/text.c (1.49), source/text.h (1.20), source/textDisp.c (1.58), source/textDisp.h (1.26), source/textP.h (1.10), source/window.c (1.176), source/window.h (1.26), util/prefFile.c (1.24): Adds an optional hairline at the wrap column. 2004-10-01 10:06 yooden * doc/help.etx (1.78), source/file.c (1.89), source/help_data.h (1.74), source/menu.c (1.117), source/nedit.h (1.60), source/preferences.c (1.128), source/preferences.h (1.43), util/getfiles.c (1.31), util/getfiles.h (1.8): Adds a widget to (un)display hidden files in the FSB. 2004-10-01 09:50 yooden * doc/help.etx (1.77), source/menu.c (1.116), source/nedit.h (1.59), source/preferences.c (1.127), source/search.c (1.72), source/search.h (1.23), source/window.c (1.175): Adds a smart search mode, which toggles caseness in regex searches. ============================================================================ 2004-09-30 REL-5-5 branch created ============================================================================ 2004-09-30 22:52 n8gray * README (1.47): Oops -- missed a bit of CVS conflict detrius. 2004-09-30 22:51 n8gray * Makefile (1.19), README (1.46), ReleaseNotes (1.28), source/nc.c (1.45): Updating version information in preparation for 5.5 release. 2004-09-30 21:35 edg * README (1.45): Removed obsolete "KNOWN DEFECTS" section. 2004-09-30 11:31 edg * ChangeLog (1.40): Regenerated (cvs2cl.pl -b -r -t --accum --gmt). 2004-09-30 11:30 edg * README (1.44), ReleaseNotes (1.27): Updates for 5.5 2004-09-16 00:50 n8gray * source/: menu.c (1.115), window.c (1.174): Addressing Bug 1023089: can't open new tab. Let's see if this phrasing is more clear. The File menu now has either: New New Window or: New New Tab depending on the user's "open new files in..." preference. 2004-09-07 06:19 n8gray * source/menu.c (1.114): Fixed spelling of incrementalSearchLine resource as reported by Arne Forlie. 2004-09-02 10:50 edg * source/userCmds.c (1.50): Shell command dialog: renamed window to document. 2004-09-02 10:49 edg * source/: nedit.c (1.83), shell.c (1.35): Fixes for the state of the File->Close menu item (bug reported by Arne Førlie). Also made the output of a shell command go to a new window or a new tab, depending on the user preference wrt. tabbed editing. 2004-09-01 20:42 n8gray * source/menu.c (1.113): Fix the "New Tab" menu item in the tab context menu. 2004-09-01 20:19 n8gray * source/window.c (1.173): Clean out dead variables in DetachDocument. 2004-09-01 15:50 tksoh * source/window.c (1.172): Fix for SF Bug #1020035: Detaching/Moving non-top tab should not change top tab. 2004-08-31 23:37 n8gray * source/window.c (1.171): This should fix bug 1011233 - Openning new window from a tabbed window diminishes size. The comment says that the previous version was supposed to reduce flickering but it caused these size problems and I didn't notice any appreciable difference in the flickering without it. 2004-08-26 06:51 n8gray * Makefile (1.18), README (1.43), ReleaseNotes (1.26), source/nc.c (1.44) (utags: BETA-5-5-RC2): Updating version info for RC2. 2004-08-24 12:12 edg * ChangeLog (1.39, BETA-5-5-RC2): Regenerated (cvs2cl.pl -b -r -t --accum --gmt). 2004-08-24 11:37 edg * source/file.c (1.88, BETA-5-5-RC2): Fix for SF bug #999021 Using exit() in a macro causes hang. 2004-08-20 19:33 n8gray * doc/help.etx (1.76), source/help_data.h (1.73), source/menu.c (1.112), source/nedit.c (1.82), source/nedit.h (1.58), source/preferences.c (1.126), source/window.c (1.170), source/window.h (1.25): Committing Tony Ballinski's fix for bug #1005442: documentation for rangeset_set_mode( r, type ) not clear 2004-08-20 16:37 edg * doc/help.etx (1.75), source/help_data.h (1.72), source/help_topic.h (1.63), source/regularExp.c (1.25): Fix for SF bug #1008656: word delimiters ignored. Partially reverted the implementation of '<', '>', and \B back to the pre-5.4 behaviour, without giving up the fix for the problem that we wanted to solve in 5.4. Word boundaries are now again defined in terms of the delimiter set (which makes things more consistent overall), but word boundary operators still test both the previous and the next character (the pre-5.4 version only tested one character, causing surprising matches, eg., between to spaces). 2004-08-16 10:12 edg * doc/help.etx (1.74), source/help_data.h (1.71), source/help_topic.h (1.62): Documentation fix for regex boundary expression semantics. 2004-08-15 02:09 tksoh * Microline/XmL/: Folder.c (1.6), FolderP.h (1.5), XmL.h (1.6): Added resource XmLFolder.minTabWidth to fix SF bug #1005064, where tabs were getting wrong sizes when too many tabs were opened. 2004-08-12 16:51 edg * source/window.c (1.169): Avoid replace dialog button sensitivity updates when the dialog is not mapped and the selection is altered. In this way many indirect status checks for all files are avoided (triggered by updating the sensitivity of the "Multiple Files..." button). 2004-08-12 13:43 edg * source/window.c (1.168): Fix for SF bug #1006830: "Warn on Exit" doesn't work sometimes. 2004-08-12 09:06 edg * source/file.c (1.87): Avoid "File Modified Externally" dialogs for tabs that are not visible (similar to minimized windows). 2004-08-10 22:28 yooden * source/nedit.c (1.81): Adds limits.h. 2004-08-09 22:20 n8gray * README (1.42), util/misc.c (1.69): It appears I never committed the updated RC1 README file. Here it is. This also contains a minor correction to the comment documentation for QueryDesktop. There have been no functional changes. 2004-08-09 16:48 edg * source/: nedit.c (1.80), window.c (1.167): Restored the "invalid default virtual key binding" workaround that had become effectively disabled due to the shell widget hierarchy reorganization. (Bug report at discuss list by Timothy Paige: page-up,page-down on sun keyboard.) 2004-08-04 17:43 n8gray * source/preferences.c (1.125): Bump the prefs file version to prevent repeated conversion. 2004-08-04 08:05 n8gray * source/preferences.c (1.124): Notify user when prefs file gets changed for 5.5. 2004-08-01 10:06 yooden * source/file.c (1.86), source/help.c (1.102), source/highlight.c (1.50), source/highlightData.c (1.68), source/macro.c (1.89), source/menu.c (1.111), source/preferences.c (1.123), source/search.c (1.71), source/selection.c (1.31), source/shell.c (1.34), source/smartIndent.c (1.36), source/tags.c (1.59), source/userCmds.c (1.49), util/DialogF.c (1.31), util/fontsel.c (1.28), util/getfiles.c (1.30), util/misc.c (1.68), util/misc.h (1.25), util/printUtils.c (1.25): Dialog OK's are getting less blanks, more margin. 2004-08-01 07:55 yooden * doc/help.etx (1.73), source/help_data.h (1.70), source/help_topic.h (1.61): Fixes some leftovers of the licence clarification. 2004-07-29 13:47 tringali * util/DialogF.c (1.30): SF #999820 - spaces in dialog button mnemonics 2004-07-28 18:02 n8gray * source/: text.c (1.48), window.c (1.166): Fix for bug 996786: Problems with Overtype mode. 2004-07-27 18:25 n8gray * README (1.41): Minor grammatical fix. 2004-07-27 18:23 n8gray * README (1.40): Updated feature list for 5.5. 2004-07-26 22:52 n8gray * util/system.h (1.16): Fixes test for PowerPC architecture in OS X. 2004-07-25 22:24 yooden * Makefile (1.17): Increase Posixication level. 2004-07-24 17:41 yooden * README (1.39), doc/help.etx (1.72): License change, step 4: Mention of the Mozilla project. 2004-07-23 18:52 n8gray * source/window.c (1.165, BETA-5-5): Fix for bug 996216: Detach Tab/Move tab don't keep non-default word delimiters. 2004-07-23 18:40 n8gray * source/window.c (1.164): Purely cosmetic. Renamed cloneTextPane to cloneTextPanes and moved functions around so that cloneTextPanes, cloneDocument, cloneUndoItems, DetachDocument, and MoveDocument are together. 2004-07-23 18:07 n8gray * source/window.c (1.163): Applied TK Soh's patch to correct the colors of detached multi-pane windows.

Fix due to T. Haude with slight modification. (argument scanning stops if it sees "--".) 2004-07-15 18:47 edg * ReleaseNotes (1.25, BETA-5-5): Added bug #987102 to the list of bugs fixed in 5.5. 2004-07-15 18:39 edg * source/regularExp.c (1.23): Fix for SF bug #987102: segmentation fault on replace. Regex recursion is now limited to 10000. The API could still be extended to handle errors more gracefully (error messages are currently written to stderr). 2004-07-15 18:30 edg * source/nedit.c (1.76): Added Lesstif-specific suppression of harmless but annoying warnings generated by non-production versions of the library. Developers can see the suppressed messages by adding -DDEBUG_LESSTIF_WARNINGS to their compile flags. So far, I've added 3 messages to the suppression list, but the list can easily be extended if more of these messages show up. 2004-07-15 18:26 edg * util/check_lin_tif.c (1.9): Added OpenMotif 2.2.3 and Lesstif 0.93.94 to the "known good" lists.

The workaround to prevent this crash was executed too late due to the reorganization of the shells. 2004-07-15 09:07 yooden * source/file.c (1.83): Small optimization in backupFileName() 2004-07-15 02:03 yooden * makefiles/Makefile.solarisx86 (1.1, BETA-5-5): Added Makefile for Solaris x86. 2004-07-15 01:47 yooden * source/: highlightData.c (1.65), preferences.c (1.120): Fixes two small issues wrt C++. 2004-07-14 19:51 n8gray * source/menu.c (1.108): There were two accelerators for 'T' in the File menu.

It wasn't as hard as I thought it would be. 2004-07-09 12:20 edg * ReleaseNotes (1.24): First stab at the release notes for 5.5. 2004-07-09 07:44 edg * util/misc.c (1.65): Inserted some casts to suppress harmless warnings on Solaris. 2004-07-08 13:07 edg * source/help.c (1.98): More fundamental fix for SF bug #982589: Help font inconsistent with window size. The help window size calculation is now based on the actual fixed font used in the help window. 2004-07-08 06:29 n8gray * Makefile (1.16, BETA-5-5), README (1.37), source/help_data.h (1.67), source/help_topic.h (1.58), source/nc.c (1.42): Man, that was a quick beta! Back to RC1. 2004-07-07 08:18 edg * ChangeLog (1.38, BETA-5-5): Regenerated (cvs2cl.pl -b -r -t --accum --gmt). 2004-07-07 01:39 n8gray * README (1.36), makefiles/Makefile.macosx (1.6): Updating some OS X documentation. 2004-07-07 03:14 n8gray * Makefile (1.15), README (1.35), source/help_data.h (1.66), source/nc.c (1.41): I guess we should go to BETA1 before RC1. 2004-07-07 02:51 n8gray * Makefile (1.14), README (1.34), source/help_data.h (1.65), source/help_topic.h (1.57), source/nc.c (1.40): Updating version information for 5.5RC1. 2004-07-03 00:16 edg * source/highlightData.c (1.64): Minor update to the Python patterns: added new built-in functions, exceptions, warnings, ... that were introduced in Python 2.3. 2004-06-30 13:56 edg * source/help.c (1.97): Increased the help window size from 65 to 75 columns as a workaround for the window becoming smaller due to changes in the font specifications. (SF bug #982589: Help font inconsistent with window size) 2004-06-28 10:23 edg * source/menu.c (1.106): Fix for SF bug #933146: VMS Open Previous DB file error. 2004-06-23 15:25 edg * source/server.c (1.30): Race condition fix for SF bug #978104: nedit -sync option. The server missed the first property change in synchronous mode. 2004-06-21 09:42 edg * doc/help.etx (1.69), source/help_data.h (1.64), source/help_topic.h (1.56): Cross-reference fixes (Yury Burkatovsky). 2004-06-13 03:08 tksoh * source/window.c (1.160): Fixed shrinking-window bug on some window manager such as Metacity, where window would shrink when switching between documents with different font size. 2004-06-11 12:33 edg * Microline/XmL/XmL.h (1.3): Fixed a #define collision when compiling with OM 2.2.3. 2004-06-11 12:16 edg * source/: menu.c (1.105), nedit.h (1.56), window.c (1.159): Fixes for SF bug #779454: SGI_CUSTOM & windows names.

This could eventually result in accesses to destroyed bg menu items (and crashes), but only when the tabs use different language modes. That's why crashes were rather rare (and the illegal accesses didn't always result in a crash). 2004-06-08 17:36 edg * doc/help.etx (1.67), doc/nc.pod (1.5), doc/nedit.pod (1.6), source/help_data.h (1.62), source/help_topic.h (1.54): Help updates: tabbed editing and incremental search bar (Joerg Fischer). 2004-06-08 17:30 edg * source/server.c (1.29), util/misc.c (1.64), util/misc.h (1.23): Committed SF patch #963120: Open tab in window on current desktop. New files opened via nc no longer appear in a tab of some pseudo-random window, possible on a different window manager desktop, but on a window of the current desktop. If no window exists on the current desktop, a new one is created. Requires the window manager to be EWMH compliant, but falls back to the old behaviour for non-compliant wms. 2004-06-08 17:08 tringali * source/shell.c (1.31): Fix from Tony Balinski: close unused fds so that shell commands can be invoked asynchronously.

I still don't understand why it didn't work for me before, but what the heck. Also it looks like I regenerated the help files. No changes there other than the dates at the top. 2004-04-14 15:12 edg * source/window.c (1.141): Warning fix (Andrew Stanaski). 2004-04-14 09:44 edg * source/: nedit.c (1.68), server.c (1.28): Additional fixes for potential crashes due to -do macro commands closing windows. 2004-04-14 05:45 tksoh * source/: nedit.c (1.67), server.c (1.27): Fixed coredump when running -do closed() or detach_document() with nc or nedit, or when files fail to open. Also corrected the behavior on VMS so that -do will only apply onto the first file globbed from the wildcard specified. 2004-04-14 00:49 n8gray * source/: nedit.c (1.66), window.c (1.140): Changed so that alignment of the filenames in tabs isn't hardwired. I edit lots of files that have the same prefix, e.g. mmc_ext_XXX.ml, and if too many tabs get opened then I end up with 25 identical tabs. This is much less of a problem if the text is right-aligned, since the .ml suffixes take up less space. You can try this out by setting the resource "*tab.alignment: XmALIGNMENT_END". One improvement would be to also put the "*" that indicates a file is modified on the right if the titles are right-aligned. I tried to implement that but for some reason couldn't read the setting of the alignment resource successfully. 2004-04-14 00:14 n8gray * source/window.c (1.139): Fixed the code to get the next tab on tab close/detach so that the correct tab is chosen when tabs are sorted. 2004-04-01 12:48 tksoh * source/window.c (1.138): Re-enabled window auto-resizing on (un)display of line numbers for multi-tab windows. Disabling auto-resize on font change alone would be enough to fix the growing-window bug. 2004-04-01 10:29 tksoh * source/window.c (1.137): Fixed BadMatch error when linking to various releases of Lesstif version 1.2 (no problem with v2.x), if we use XCreateBitmapFromData() to created bitmaps for buttons. 2004-04-01 02:50 tksoh * source/textDisp.c (1.56): Fixed BadWindow error when opening help window, introduced by the recent window auto-resize patch. 2004-04-01 01:38 tksoh * source/window.c (1.136): Fixed bug where the detached document would get an incorrect number of rows, when the document contain highlighting fonts with sizes differ from the primary font. For now there'd be some flickers due to the resizing of the detached window by syntax highlighting, etc - something that we are to address later - but the rows will at least be correct. 2004-03-31 15:02 tksoh * source/: highlight.c (1.46), textDisp.c (1.55), window.c (1.135): Disabled window auto-resizing, triggered by font change or (un)display of line numbers, for multi-tab windows. 2004-03-31 12:31 tksoh * source/: nedit.h (1.52), search.c (1.67), window.c (1.134): Applied SF patch #891884: Add Find and Clear buttons to i-search 2004-03-29 14:42 tksoh * source/userCmds.c (1.45): Fixed coredump when invoking BG menu on lower split-panes. 2004-03-28 12:15 yooden * .cvsignore (1.3), doc/.cvsignore (1.5), source/.cvsignore (1.5), util/.cvsignore (1.4): Moves *.bck to global ignore file. 2004-03-25 17:37 tksoh * source/: menu.c (1.99), window.c (1.133): Removed unused functions. 2004-03-25 07:12 n8gray * .cvsignore (1.2), doc/.cvsignore (1.4), doc/help.etx (1.62), source/.cvsignore (1.4), source/help_data.h (1.56), source/help_topic.h (1.48), source/textDrag.c (1.9), util/.cvsignore (1.3): Updated the help files to document action routines for all menu items.

Error pattern of color-only patterns was copied erroneously. 2004-01-10 06:12 tksoh * source/userCmds.c (1.37): Fixed coredump when invoking Macro/Shell/Background commands from tear-offs. 2004-01-09 05:56 tksoh * source/userCmds.c (1.36): Bugfix: when invoked by keyboard shoft-cuts, macro and shell commands were always executed in the first buffer created, or coredumped if the first buffer had been closed. 2004-01-08 06:19 tksoh * source/: macro.c (1.78), macro.h (1.5), shell.c (1.28), shell.h (1.6), window.c (1.97): Bugfix: cursor and statsline now reflect if macro/shell commands are in progress in each individual buffer. 2004-01-06 06:25 n8gray * source/macro.c (1.77): Patch monkey see, patch monkey do. Tony says fix rangeset bug, patch monkey fix rangeset bug. Ook. Fixes SF bug #871209 2004-01-06 02:38 tksoh * source/: menu.c (1.85), userCmds.c (1.35), window.c (1.96): Improved handling of tear-off (Macro, Shell and Windows) menus: i) fixed shrink-expand bugs; ii) tear-offs stay up when buffers are closed. 2004-01-02 10:32 tksoh * source/window.c (1.95): window manager's size hints should follow the top buffer. 2003-12-31 02:25 tksoh * source/window.c (1.94): Bugfix: bookmarks were lost when detaching/attaching buffers. (Uwe Lehnert) 2003-12-31 01:22 tksoh * source/window.c (1.93): Bugfix for crash when navigating through buffers. 2003-12-30 15:32 tringali * source/nedit.c (1.57): Also put back XmLFolder resources. 2003-12-30 15:19 tringali * source/nedit.c (1.56): Revert to fallback resources. The merging didn't work as I expected. 2003-12-29 10:58 tksoh * source/window.c (1.92): Applied temporary workaround for disappearing-text-window bug when linking to Lesstif (ver 0.93.18 & 0.93.46 tested) 2003-12-28 17:30 tringali * source/nedit.c (1.55): New default resource scheme. We enter resources directly via Xrm calls, instead of fallback resources. This should avoid version skew problems when an app-defaults file has been installed against our wishes. In particular, when there is an app-defaults file out there, we should now merge all the built-in and external resources. Fallback resources would simply discard the built-in resources in favor of the ones in the file, and this frequently would cause missing resources if the file was out of date. 2003-12-28 17:25 yooden * source/: highlightData.c (1.59), preferences.c (1.104): Changes LaTeX patterns (Jörg Fischer) and adds comment macro (Sergei Haller). 2003-12-28 17:25 tringali * source/window.c (1.91): Remove

$args[] to the NEdit Macro pattern. 2003-12-26 10:14 tksoh * source/window.c (1.90): bugfix: text colors not correctly set for new tabs. 2003-12-25 07:09 tksoh * Makefile (1.13): Committed patch

This is the standard way of structuring multiple-window applications, and we've been standing on our heads trying to work around problems the old approach causes (no visual propogation to children, no way to address types of top-level windows by name in resources, session management bugs, etc).

(This may be exported by Motif but there is no header to tell you if it is there or not.) 2002-09-06 19:21 n8gray * source/calltips.c (1.2): Changing calltip label widget name from "calltipW" back to "calltip" so that resources work as advertised. 2002-09-06 19:13 n8gray * doc/help.etx (1.27), doc/nedit.doc (1.26), doc/nedit.html (1.20), source/Makefile.common (1.11), source/Makefile.dependencies (1.18), source/calltips.c (1.1), source/calltips.h (1.1), source/help_data.h (1.23), source/help_topic.h (1.17), source/macro.c (1.49), source/tags.c (1.45), source/tags.h (1.13), source/text.c (1.34), source/textDisp.c (1.37), source/textDisp.h (1.15): New features: Positioning of calltips can be controlled more precisely using optional arguments to calltip(). These include "center", "right", "above", and "strict". Non-strict, non-anchored calltips will always show up *somewhere* on-screen even if the cursor is not on-screen. Modifications: Refactored calltip UI code into calltips.c/.h. Updated help files, makefiles, and dependencies. Cleaned up tags.c/.h somewhat. 2002-09-05 23:17 slobasso * source/: interpret.c (1.30), parse.y (1.21), parse_noyacc.c (1.4): made the following work when arrayaExpression is anything that returns an array as the result: for (x in arrayaExpression) { } 2002-09-05 23:15 slobasso * source/nedit.c (1.36): fixed Cardinal vs int compare warning. 2002-09-05 17:48 tringali * doc/help.etx (1.26), source/nedit.c (1.35), util/misc.c (1.43), util/misc.h (1.15): Acquire default colors and fonts from the environment if using the default visual. 2002-09-04 08:40 n8gray * source/: tags.c (1.44), textDisp.c (1.36): Minor cleanup of tags.c (it could use a lot more). Also improved calltips so that they try not to go off the edges of the screen. Thanks to TK, from whom I stole much code. Since he stole his tooltip code from me, the circle is complete. :^) 2002-09-04 05:58 n8gray * source/: textDisp.c (1.35), textDisp.h (1.14): Calltips should finally update on any vertical cursor movement! Plus, non- anchored calltips maintain their X positions on redrawing. Also, I found out that textD->cursorX/cursorY are *not* a reliable way to get the X/Y positions of the insertion point, so other potential calltips bugs might be fixed. This is one of those nice commits where I've removed almost as many lines as I've added. :^) 2002-09-03 01:10 n8gray * source/: file.c (1.52), nedit.h (1.28), window.c (1.68): This should fix the worst of the problems in file.c. There are still potential problems if you lose read permission on a file as you're editing it, but I wanted to commit what's done so far. 2002-09-02 23:18 n8gray * source/textDisp.c (1.34): Fixing problem where scroll-wheel-down on empty files caused erroneous scrolling. It was a problem with mixing Cardinal (unsigned) and signed values. I took the approach of casting cursorVPadding to int before using it, since it's nice to have Xt reject negative values automatically. 2002-09-02 08:55 edg * source/textDisp.c (1.33): Fix for crash bug reported through develop@: regex bug using ^.* BufCopyFromBuf() could be called with invalid paramaters in continous wrapping mode. 2002-08-31 15:14 yooden * doc/help.etx (1.25), doc/nedit.doc (1.25), doc/nedit.html (1.19), doc/setext (1.8), doc/setext-info.txt (1.2), source/help_data.h (1.22): Another help update, some setext documentation and a minor setext change. 2002-08-31 08:48 yooden * source/: help_data.h (1.21), help_topic.h (1.16): Corrected Help, second batch. 2002-08-31 08:46 yooden * doc/: help.etx (1.24), nedit.doc (1.24), nedit.html (1.18): Slight correction in help.etx. 2002-08-31 07:24 n8gray * doc/help.etx (1.23), doc/nedit.doc (1.23), doc/nedit.html (1.17), source/help_data.h (1.20), source/help_topic.h (1.15), source/text.c (1.33), source/text.h (1.9), source/textDisp.c (1.32), source/textP.h (1.5): Committing the edge-phobic cursor patch, with documentation and without tab-space mixing. (The new resource is nedit*text.cursorVPadding by the way.) 2002-08-31 00:52 slobasso * source/: interpret.c (1.29), interpret.h (1.10), parse.y (1.20): Lots of array code cleanup including fixes for the following formats: x[9][8] = 6 delete x[4][2][] ++x[4] x[3]-- x[4][5] += 7 ... and many more. Also fixed some cases in which array aliasing could occur. Arrays are supposed to have VALUE semantics. 2002-08-28 14:14 tringali * source/preferences.c (1.65): Revive upgrade message to 5.4 file format 2002-08-27 08:05 edg * source/textDisp.c (1.31): Fixes for SF #600175: Coredump when dismissing resized window Array bounds read & write fixes in calcLineStarts() when number of visible lines becomes zero (only possible in help windows). Avoid scrollbar slider size < 1 warning (which was harmless but annoying). 2002-08-27 05:39 n8gray * source/: file.c (1.51), undo.c (1.14), undo.h (1.6): Committing the file deletion notification patch. I used a specialized message for ENOACCES but used strerror output along with a suggested cause (deletion or relocation by another program) in the other cases, since there are several possible causes of stat() failure. I'm committing the patch despite the minor controversy over the message text because it's better to have some message than none at all. There is still much bogosity in file.c, including another place where stat() failure causes no warning. 2002-08-23 07:52 n8gray * source/textBuf.c (1.22): Fixed a miscalculation in overlayRectInLine that could cause extra letters to be deleted during rectangular drags over tabs. See SF bug #557225 "rect. selection drag buglet" for a description of the problem. 2002-08-23 00:52 slobasso * source/interpret.c (1.28): Fixed bug that didn't allow built in array variables to be iterated with a for loop. 2002-08-22 23:52 slobasso * source/window.c (1.67): Remove unused variables. 2002-08-22 18:43 slobasso * source/userCmds.c (1.28): Fix size calculation and escape characters in menu item names. 2002-08-22 08:40 n8gray * source/undo.c (1.13): Fixed SF bug #578551 "Scrolling to searched/altered selection" by adding MakeSelectionVisible() calls to Undo and Redo. 2002-08-22 08:10 n8gray * source/window.c (1.66): Nuking trailing whitespace from my last commit. 2002-08-22 08:05 n8gray * source/window.c (1.65): MakeSelectionVisible in window.c was not paying attention to wrapped lines. To see the problem in an older version: 1. Open a large file and scroll to the center somewhere 2. Enable continuous wrapping and resize window so lots of lines wrap 3. Select a word and make a mark with Alt+M,a 4. Page Up or Down for several screens 5. Go to the mark with Alt+G,a If there are enough wrapped lines between your position and the mark then the selection and the cursor will be completely offscreen. Also restructured the function so that horizontal scrolling is not bypassed prematurely. 2002-08-21 13:21 tringali * source/help.c (1.83): Remove duplicate widgets caused by a bum merge. 2002-08-21 07:19 n8gray * source/file.c (1.50): Fixed bug where clicking on the WM's close button in an unsaved and untitled buffer, answering yes to the "Save before closing" dialog, then aborting the Save-As dialog led to the window being closed and the changes being lost. The function CloseFileAndWindow wasn't returning FALSE when the Save-As failed. 2002-08-19 21:41 tringali * source/preferences.c (1.64): Remove "alpha" versioning - it wasn't forwards compatabile, and there were no auto-upgrades done despite the message printed. 2002-08-19 07:22 n8gray * source/textDisp.c (1.30): Calltips are now redrawn on TextDMoveUp and TextDMoveDown. This should help those who end up with cursors behind calltips when entering multi-line function calls. 2002-08-17 14:28 yooden * source/window.c (1.64): Removed unused variables. 2002-08-16 14:43 tringali * source/file.c (1.49): Fix hang caused by posting the "reload" dialog box on a hidden window (during multi-file replace validation). 2002-08-15 19:03 n8gray * source/: file.c (1.48), window.c (1.63): Fixed the flickering stats line problem (SF bugs 595106, 594838).

VERSION 5.6 Version 5.6 is a maintenance release. See the ReleaseNotes file for a more detailed description of these new features and a list of bugs fixed in this version. BUILDING NEDIT Pre-built executables will be available for many operating systems, including most major Unix and VMS systems. Check out the NEdit web page at http://nedit.org If you have downloaded a pre-built executable you can skip ahead to the section called INSTALLATION. Otherwise, the requirements to build NEdit from the sources are: - ANSI C89 system (compiler, headers, libraries) - make utility (eg, GNU make) - X11R5 development stuff (headers, libraries), or newer - Motif 1.2 or above (Motif 1.1 might work, but is no longer supported) This GUI library is a standard part on most systems which have an X11 installation. Most commercial Unix systems feature this, others may require a separate installation. A "free" (LGPL'ed) alternative to Motif, called LessTif, is available. See the LessTif section under PLATFORM SPECIFIC ISSUES for details. Optionally one may use: - yacc (or GNU bison) The two directories called 'source' and 'util' contain the sources for NEdit. 'util' should be built first, followed by 'source'. The makefile in NEdit's root directory can be used to build both in sequence if your system is one of the supported machines and no modifications are necessary to the makefiles. To build NEdit from the root directory, issue the command: 'make '; where is one of suffixes of a makefile in the directory 'makefiles'. For example, to build the Silicon Graphics version, type: make sgi If everything works properly, this will produce two executables called 'nedit' and 'nc' in the directory called 'source'. The Source Directories Since executables are already available for the supported systems, you are probably not just rebuilding an existing configuration, and need to know more about how the directories are organized. The util directory builds a library file called libNUtil.a, which is later linked with the code in the source directory to create the nedit executable. The makefiles in both source directories consist of two parts, a machine dependent part and a machine independent part. The machine dependent makefiles can be found in the directory called 'makefiles', and contain machine specific header information. They invoke a common machine independent part called Makefile.common (which in turn includes also Makefile.dependencies). To compile the files in either of these directories, copy or link one of the system-specific makefiles from the directory 'makefiles' into the directory, and issue the command: make -f Makefile. (where is the makefile suffix). Alternatively, you can name the file 'Makefile' and simply type "make". If no makefile exists for your system, you should start from Makefile.generic, which is extensively commented. Contact the developer at develop@nedit.org for help. Building NEdit on VMS Systems A command file is provided for compiling and linking files from all source directories. To build on OpenVMS change directory into [.makefiles] and run 'buildvms.com'. Additional Settings Some C preprocessor macros may be used to en/disable certain parts of the code. Usually this correponds to some non-important features being selected or certain workarounds for platform-specifc problems. Those which might be useful on more than one platform are documented in makefiles/Makefile.generic. Note that a special compilation flag, namely REPLACE_SCOPE, is currently available. Its purpose is to allow the evaluation of two alternative (but functionally equivalent) Replace/Find dialog box layouts. By default, NEdit is built with a Replace/Find dialog containing 2 rows of push buttons. Compiling with the REPLACE_SCOPE flag enables an alternative layout with a row of radio buttons for selecting the scope of the replace operations. Eventually, one of these alternatives will probably disappear, but up to now, the NEdit developers have not been able to decide which one to drop. Please give them both a try and let us know which one you prefer (via the discuss mailing list, for instance). Another compilation flag, HAVE__XMVERSIONSTRING, adds additional information about the Motif version in the menu item "Help->Version" or the command line option "-version". Whether this is available on your system depends on the Motif implementation. It is known to work with OpenMotif 2.1.30, and Motif on Solaris 2.6 and AIX 4.3.3. INSTALLATION NEdit consists of a single, stand-alone executable file which does not require any special installation. To install NEdit on Unix systems, simply put the nedit executable in your path. To use NEdit in client/server mode (which is the recommended way of using it), you also need the nedit client program, nc, which, again, needs no special installation. On some systems, the name nc may conflict with the 'netcat' program. In that case, choose a different name for the executable and simply rename it. The recommend alternative is 'ncl'. Don't forget to put the man-pages for nedit and nc into a place where your man command is able to find them (e.g. /usr/man/man1/nedit.1), and don't forget to rename nc.man to ncl.man if you've renamed nc to ncl. On VMS systems, nedit and nc must be defined as a foreign commands so that they can process command line arguments. For example, if nedit.exe were in the directory mydir on the disk called mydev, adding the following line to your login.com file would define the nedit command: $ ned*it :== $mydev:[mydir]nedit.exe RUNNING NEDIT To run NEdit, simply type 'nedit', optionally followed by the name of a file or files to edit. On-line help is available from the pulldown menu on the far right of the menu bar. For more information on the syntax of the nedit command line, look under the heading of "NEdit Command Line". The recommended way to use NEdit, though, is in client/server mode, invoked by the nc executable. It allows you to edit multiple files within the same instance of NEdit (but still in multiple windows). This saves memory (only one process keeps running), and enables additional functionality (such as find & replace accross multiple windows). See "Server Mode and nc" in the help menu for more information. If you are accessing a host Unix system from a remote workstation or X terminal, you need to set the Unix environment variable for your display: csh: % setenv DISPLAY devicename:0 sh, ksh, bash, zsh: % export DISPLAY=devicename:0 where devicename is the network node name (hostname) of the workstation or X terminal where you are typing. On VMS systems, the equivalent command is: $ set display/create/node=devicename PLATFORM SPECIFIC ISSUES Systems with LessTif, rather than Motif libraries As of Lesstif 0.93.18, NEdit is very stable with Lesstif. You can get the latest LessTif version from http://www.lesstif.org. If you are having trouble building or running NEdit with LessTif, remember there are pre-compiled statically linked executables available from our website. Known bugs which might show off in NEdit linked with LessTif include: 1) Some dialogs which are intended to be modal (prevent other activity while up) are not, and doing other actions while these dialogs are up can cause trouble (.89.9+) 2) Switching to continuous wrap mode, sometimes the horizontal scroll remains partially drawn after the change, rather than disappearing completely as it should. (.89.9+) 3) Secondary selection operations are not yet supported in text fields. 4) Status bar is blank after usage of Incremental Search field (0.93.18+-) Linux Systems Red Hat Linux, as of version 8.0, no longer automatically reads X resources out of the ~/.Xdefaults file. Instead, it reads a file named ~/.Xresources. Any customizations stored in ~/.Xdefaults will not be honored, for all X applications. To fix this, copy the resources into ~/.Xdefaults, or link the files together. The default key bindings for arrow keys in fvwm interfere with some of the arrow key bindings in NEdit, particularly, Ctrl+Arrow and Alt+Arrow. You may want to re-bind them either in NEdit (see Customizing -> Key Binding in the Help menu) or in fvwm in your .fvwmrc file. Some older Linux distributions are missing the /usr/X11R6/lib/X11/XKeysymDB file, which is necessary for running Motif programs. When XKeysymDB is missing, NEdit will spew screenfulls of messages about translation table syntax errors, and many keys won't work. You can obtain a copy of the XKeysymDB file from the contrib sub-directory of the NEdit distribution directory. Linux binaries were built statically by default before NEdit 5.6. This has changed with 5.6 to make better use of distribution-specific features. The call 'make linux' will now create binaries dynamically linked to Motif or Lesstif; calling 'make linux-static' will create static binaries. Mac OS X Systems NEdit is an X Window application and thus requires an X Window server, such as Apple's X11.app or XFree86.org's XDarwin, to be running. If you are building NEdit yourself, you will probably need to edit makefiles/Makefile.macosx to select the correct version of Motif. There are comments in the makefile to help you do this correctly. Note that the developers use the OpenMotif 2.1.30 package available (at the time of writing) at: http://msg.ucsf.edu:8100/~eric/ SGI Systems Beginning with IRIX 6.3, SGI is distributing a customized version of NEdit along with their operating system releases. Their installation uses an app-defaults file (/usr/lib/X11/app-defaults/NEdit) which overrides the default settings in any new nedit version that you install, and may result in missing accelerator keys or cosmetic appearance glitches. If you are re-installing NEdit for the entire system, just remove the existing app- defaults file. If you want to run a newer copy individually, get a copy of the app-defaults file for this version the contrib sub-directory of the distribution directory for this version on ftp.nedit.org (/pub// contrib/nedit.app-defaults), and install it in your home directory or set the environment variables XAPPLRESDIR or XUSERFILESEARCHPATH to point to a directory and install it there. In all cases, the file should be named simply 'NEdit'. No additional installation or resource settings are necessary on IRIX systems before 6.3 HP-UX Systems If you are using HPVUE and have trouble setting colors, for example part of the menu bar stubornly remains at whatever HPVUE's default is, try setting: nedit*useColorObj: False IBM AIX Systems Due to an optimizer bug in IBM's C compiler, the file, textDisp.c, must be compiled without optimization on some AIX systems. Solaris (SunOS 5.3 and beyond) Systems The nedit_solaris executable may require the environment variable OPENWINHOME to be set to the directory where Open Windows is installed. If this is not set properly, NEdit will spew screenfulls of messages about translation table syntax errors. Solaris 2.4 -- Add -DDONT_HAVE_GLOB to the CFLAGS line in Makefile.solaris. Solaris 2.5 -- Solaris 2.5 systems were shipped with a bad shared Motif library, in which the file selection dialog (Open, Save, Save As, Include, etc.) shows long path names in the file list, but no horizontal scroll bar, and no way to read the actual file names. Depending on your system, the patch is one of ID# 103461-07, # 102226-19, or # 103186-21. It affects all Motif based programs which use the library. If you can't patch your system, you might want to just try the nedit_sunos executable (from ftp.nedit.org /pub/), which is statically linked with a good Motif. You can also set the X resource: nedit.stdOpenDialog to True, which at least gives you a text field where you can enter file names by hand. Solaris 2.6 -- If you're experiencing performance problems (windows come up slowly), the patch for Sun's shared Motif library is ID# 105284-04. Installing the patch alone will improve nedit's performance dramatically. The patch also enables a resource, *XmMenuReduceGrabs. Setting this to True will eliminate the delay completely. SunOS 4.x Systems On some SunOS systems, NEdit will also complain about translation table syntax errors. This happens when Motif can't access the keysym database, usually located in the file /usr/lib/X11/XKeysymDB. If this file exists on your system, but NEdit fails to locate it properly, you can set the environment variable XKEYSYMDB to point to the file. If you can't find the file, or if some of the errors persist despite setting XKEYSYMDB, there is a XKeysymDB which you can use to update or replace your /usr/lib/X11/XKeysymDB file available in the contrib sub-directory of the NEdit distribution directory. If you don't want to change your existing XKeysymDB file, make a local copy and set XKEYSYMDB to point to it. If you find that some of the labeled keys on your keyboard are not properly bound to the corresponding action in NEdit, try the following: 1) Get a copy of motifbind.sun (for Sun standard keyboards), or motifbind.sun_at (for Sun PC style keyboards) from the NEdit contrib directory on ftp.nedit.org:/pub//contrib. 2) Copy it to a file called .motifbind in your home directory. 3) Shutdown and restart your X server. COMPATIBILITY WITH PREVIOUS VERSIONS Existing .nedit Files As of version 5.1, NEdit employs a built-in upgrade mechanism which will automatically detects .nedit files of older versions. In general, NEdit will try to convert and insert entries to match the latest version. However, in certain cases where the user has customized the default entries, NEdit will leave them untouched (except for possible syntactic conversions). As a result, the latest syntax highlighting patterns for certain languages may not get activated, for instance, if the user has customized the entries. The latest default patterns can always be activated through the Preferences->Syntax Highlighting->Recognition Patterns menu, though. Next, some version specific upgrading issues are listed. Note that non-incremental upgrading (eg., from 5.0 to 5.2) is supported too. * Upgrading from 5.4 to 5.5 - Changes in the widget hierarchy, possibly effecting resource settings In NEdit 5.4 and below, the widget hierarchy consisted of a separate widget tree for each window. This was rather unconventional and caused certain problems. In 5.5, the hierarchy was changed such that all widgets belong to a single tree with a single root widget. For instance, with 5.4, the top of the widget hierarchy for a 2-window NEdit session looks as follows: NEdit nedit +-- XmMainWindow main NEdit nedit +-- XmMainWindow main In 5.5, the same session results in the following tree: NEdit nedit +-- TopLevelShell textShell | +-- XmMainWindow main +-- TopLevelShell textShell +-- XmMainWindow main Users with advanced X-resource settings may be affected by this change and may have to adapt their resource specifications. - Minor change to the regular expression word boundary semantics In 5.4, the semantics for word boundary regular expressions ('<', '>', and '\B') were changed to behave in a more intuitive way (see Upgrading from 5.3 to 5.4 below). However, this introduced an inconsistency between the regular expressions and several other places in NEdit where word boundaries were taken into account. Therefore, the changes were partially reverted to restore consistency, but without giving up the benefits of the more intuitive word boundary definition. More in particular, a boundary between two characters is now considered to be a word boundary only if exactly one of the characters is a delimiter. This change will have little or no consequences for most users. * Upgrading from 5.3 to 5.4 - Resource syntax Basic colors, like the text foreground and background, are now true preferences. A new dialog (Preferences > Default Settings > Colors) is provided to change them, previously only changeable from X resources. Upon starting, NEdit will migrate any custom colors you have set from the old X resources. Most users will not need to do anything. However, if you used X resources to dynamically change the colors on different invocations, you will need to use the new application-level resources instead. See the .nedit file for details. In 5.3, color resources needed to be qualified by "nedit*" in order to prevent problems when the deepest color visual was not the default. This is no longer necessary, and the qualification may be removed. - New location of configuration files The default location and name of NEdit's resource files has been changed. The most important change is the fact that they can now be stored in a custom directory, defined by the NEDIT_HOME environment variable. If the variable is not set, the directory defaults to ~/.nedit. The files have been renamed as follows: ~/.nedit -> $NEDIT_HOME/nedit.rc ~/.neditmacro -> $NEDIT_HOME/autoload.nm ~/.neditdb -> $NEDIT_HOME/nedit.history For backward compatibility reasons, NEdit continues to use the old convention when these files are already present. No attempt is made to force the user to adopt the new convention. Users that would like to migrate to the new setup can do so manually by moving and renaming the files. - Changed regular expression word boundary semantics and its effect on the syntax highlighting patterns. During the 5.4 development cycle, it was noted that the implementation of NEdit's regular expression word boundary matching was rather unconventional. More in particular, the '<', '>', and '\B' patterns interpreted the boundary between any two characters of which at least one was not a word character as a word boundary. A striking effect of this was that the boundary between two spaces was considered to be a word boundary, which is obviously rather unintuitive. This has been corrected in 5.4: the boundary between two characters is a word boundary, only if exactly one of them is a word character. Several of the built-in syntax highlighting patterns (implicitly) relied on the old word boundary interpretation and they have been corrected too. However, if the user has customized some of these buggy built-in highlighting patterns, the automatic upgrading routines will NOT upgrade them in order not to loose any customizations. It is left up to the user to correct his/her customized patterns manually (using the corrected built-in patterns as a guideline). The following is a list of all language modes and patterns that have been corrected: Ada: Based Numeric Literals Awk: Numeric constant C++: numeric constant C: numeric constant CSS: property, selector pseudo class Java: decimal const, case numeric const JavaScript: Numeric Lex: numeric constant, markers Matlab: Numeric const NEdit Macro: Built-in Vars, Numeric Const Pascal: TP Numeric Values: Perl: dq string, sq string, bq string, subroutine call, numerics, re match PostScript: Number, Operator1 Python: Number SQL: data types, keywords2 Sh Ksh Bash: keywords, built ins Tcl: Keywords VHDL: Numeric Literals Verilog: Reserved WordsA, Numeric Literals, Delay Word, Pins Declaration XML: element declaration keyword Yacc: numeric constant, percent keyword, markers So, if the user has customized the highlighting definitions for any of these language modes (not restricted to the listed patterns), (s)he is strongly advised to restore the default patterns in the syntax highlighting dialog and to re-apply his/her customizations. Moreover, it is advised to check any custom language modes for potential boundary matching problems as described above. * Upgrading from 5.2 to 5.3 There are no major changes in the format of the .nedit file for version 5.2. Users that have customized the X Resources syntax highlighting pattern may consider restoring the default patterns, as they resolve a performance issue when editing the .nedit file itself, for instance. * Upgrading from 5.1 to 5.2 There are no major changes in the format of the .nedit file for version 5.2. NEdit will try to insert additional entries for the newly supported language modes and syntax highlighting patterns (CSS, Regex, and XML) and highlight styles (Pointer, Regex, Warning). Moreover, the formerly boolean 'showMatching' option will silently be converted to a tri-state value. Users that have customized some of the syntax highlighting patterns may consider restoring the default patterns, as many of them have been improved considerably. * Upgrading from 5.0 to 5.1 NEdit 5.1 makes significant changes to the syntax of regular expressions. Mostly, these are upward compatible, but two changes; introducing the brace operator, and changing the meaning of \0; are not. Brace characters must now be escaped with backslash, and & must be used in place of \0 in substitutions. NEdit 5.1 employs a built-in upgrade mechanism which will automatically detect pre-5.1 .nedit files and fix regular expressions which appear in user-defined highlight patterns. The automatic upgrade mechanism, however, can not fix regular expression problems within user-defined macros. If you have a macro which is failing under NEdit 5.1, you will have to fix it by hand. * Upgrading from pre-5.0 If you are upgrading from a pre-5.0 version of NEdit, there are significant changes to the macro language, and you are best off simply editing out the nedit.macroCommands section of your .nedit file, generating a new .nedit file, and then re-introducing your user-written commands into the new file. Most macros written for previous versions will function properly under the new macro language. The most common problems with old macros is lack of a terminating newline on the last line of the macro, and the addition of "<", ">", and now "{" to the regular expression syntax. These characters must now be escaped with \ (backslash). Also, if you have been using a font other than the default for the text portion of your NEdit windows, be sure to check the Preferences -> Default Settings -> Text Font dialog, and select highlighting fonts which match your primary font in size. Matching in height is desirable, but not essential, and sometimes impossible to achive on some systems. When fonts don't match in height, turning on syntax highlighting will cause the window size to change slightly. NEdit can handle unmatched font sizes (width), but leaving them unmatched means sometimes columns and indentation don't line up (as with proportional fonts).

It also contains change information, for users who are interested in what bugs have been fixed, and what features have been added in the current version. If you are upgrading NEdit from a version prior to 5.0, please see the notes in the README file which came with the (source or executable) distribution kit, about updating macros and font settings in your .nedit file. New Features in 5.6 - The macro variable $VERSION returns NEdit's version number. - The new macro function filename_dialog() can be used to query a file name from the user by using the usual file selection dialog. Bugs fixed in 5.6 - Fix for SF bug #2222159: File was not reload when type was changed externaly - Fix for SF bug #2149312: parse error with zero menu entries. - Force a terminating \n on macro file load time, to prevent syntax errors with statements on the last line. (util/fileUtils.c:ReadMacroFile()) (SF bug #2038921) - Fix multiple memory leaks in interpret.c:PromoteToGlobal() (SF bug #1894726) - Fix for SF bug #1908890: window title not updated. - Fix for SF bug #1730611: $match_syntax_based is not set. - Crash on window close when a "File modified externally" dialog was up (SF bug #1578869). - Crashes and artifacts when using ARGB visuals (SF bugs #1579544, #1030467, #1030192, and #1458006). - The text insertion cursor does no longer blink while typing (SF bug #906878). - The status bar reflects a changed keybinding in the shell command banner. - There is now a pattern for highlighting nested command substitution in shell scripts (SF patch #1010742). - Duplicate display bugs SF#464967 and SF#1041077 are fixed. - A typo in Ada's syntax highlighting patterns is fixed (SF bug #858874). - The shell used to run programs from the shell_command() macro function and from the Shell menu is now part of NEdit's normal settings, and no longer in the X server's settings. It also defaults to the user's login shell, not /bin/csh. This fixes SF#403738 and SF#880607. - File history is now consistent across multiple sessions (SF bug #557032). - If a macro file contains function definitions mixed with code segments the code segments were excuted in the wrong order in certain cases. This is fixed (SF bug #622291). - The current file name is (again) displayed in the Save As dialog text field. (SF bug #1451337) - A crash caused by highlighting patterns with complex regular expressions has been fixed. (SF bug #1536002) - Crashes when the maximum number of patterns in a hightlighting pattern set was exceeded, have been fixed. (SF bug #1536451) - Files are now optionally opened without format changes (SF bug #1003241). - Replace operation where the result exceeded a fixed length silently clipped the result. The limit has been increased and the behaviour on failure is now configurable. (SF bug #1015499) - NEdit can now optionally detect and avoid symlinks (SF bug #1027788). - A minor visual glitch has been fixed (SF bug #1055649). - NEdit asks the user with a dialog if it detects that a document's file is no longer accessible on disk. This dialog is changed to better match expected usage pattern (SF bug #1066144). - Various documentation bugs are fixed (SF bugs #1066765, #1078397, #1110024, #1471868) - Some minor usability bugs have been fixed (SF bugs #1371896, #1508608, #1515134, #1066692). - New highlighting pattern are now used immediately (SF bug #1117848). - Changes in case no longer modifiy the text if no change is actually performed (SF bug #1333103). - Some Linux distros ship with XKEYSYMDB set to a bogus filename which breaks all Motif applications. NEdit ignores that, and let X fall back on the default which is far more likely to work (SF bug #1564907). - Fixed a problem in the macro language on 64-bit systems (SF bug #1625283). - Long macro function names could cause a buffer overflow (SF bug #1640304). - The built-in macro "Make C prototypes" choked on some comments (SF bug #1574071). - Fixed a small bug while inserting special characters (SF bug #682004). - Fixed a translation bug which crashed NEdit on pressing osfInsert in the help window (SF bug #1772468). - Fixed bad exception handling of default macros (SF bug #1731384). New features in 5.5 - The most important new feature is the introduction of window tabs (SF patches #569287 and #893177). - More efficient string search operations for the macro language. - Auto-scrolling is now (partly) configurable through the preference menu. - Find and Clear buttons for i-search bar (SF patch #891884). - Faster user-defined menu creation (SF patch #891126). - Open documents on current desktop (SF patch #963120) - Superuser receives a warning when trying to overwrite a read-only file. - Simplified global font resources. - Macro language: added new $args[] array and removed 9 arguments limit for macros - Improved Latex & Python syntax highlighting patterns Bugs fixed in 5.5 - If underscore (_) is among the word delimiters for a language mode then word boundary regexes will work as expected. (SF bug #1008656) - Problem with writing history file on VMS (SF bug #933146). - Race condition fix for running NEdit in -sync mode (SF bug #978104). - Removed obsolete special window title treatment on SGI (SF bug #779454). - Forbid the deletion of the "Plain" Text Drawing Style (SF patch #970491). - File descriptor handling fix that allows shell commands to be invoked asynchronously. - Crash on Solaris when dragging a calltip (SF bug #925951). - Preference resource name mistakes (SF bug #884862). - Don't delete incremental backup files when incremental backups are off (SF bug #878183). - Allow zero-length ranges to be added to range sets (SF bug #871209). - Improved shell syntax highlighting patterns (SF bug #770855). - Regular expression crash fix (SF bug #987102).

New Features in 5.2 - Added built-in patterns for CSS, XML, and regular expressions (Regex). Many other pattern updates. - Support for high- and true-color systems. NEdit now will automatically select the best visual from your X server. This reduces the chance of running out of colors. - New features in the Find and Replace dialogs: o Replacement across multiple windows in a session. o Case sensitivity may be set independently of regular expressions. o Add "Replace and Find" command, which saves keystrokes when doing a large-scale find & replace. - ClearCase version-extended pathnames. - Many new macro subroutines and variables. - Array support in macros. - Range highlighting of matching delimiters. - Undo and Redo highlights the text that has changed, when visible. - Support for wheel mouse scrolling on servers that support it (XFree86). - Improved accelerator key handling. - Insert Control Code dialog accepts value in any valid C notation - Optional beeping when search operations wrap. - Additional default search styles. - Optional displaying of path names in the window list menu.

It allows them to be changed externally. Details of Regular Expression Changes in 5.1 Bug Fixes o Fixed bug that caused character classes with a character range not to work properly if one of the range characters was an escaped character. Improvements In Existing Features o Increased maximum number of capturing parentheses from 40 to 50. o Removed optimization that uses `must match' strings (it didn't work and caused more problems than it solved.) o Improved error messages. o Improved Start-Of-Line and End-Of-Line detection by the `^', `$', and the new `\B' (see below) anchors. The Start-Of-Word and End-Of-Word anchors `<' and `>' where not enhanced due to syntax color highlighting pattern compatibility issues. o Changed code to use "unsigned char" in most cases instead of "signed char". Also, use of ANSI character functions (e.g. isdigit(), isspace()) were added wherever possible. These changes should improve support for locales other than "C", for example character sets with accented characters. o Added character escapes for: - \e ASCII escape character (for environments that use the EBCDIC character set, set the EBCDIC_CHARSET compiler symbol to get the EBCDIC equivalent escape character.) - \- minus sign - \{ left brace - \} right brace o Removed the `\"' escape since `"' is not a meta character. o In order to support numeric escapes, use of `\0' as a synonym for `&' in replacement strings was removed. `\0' now signals the start of a numeric (octal) escape sequence (see below.) o Minor tweaks for improved performance. Enhancements o Octal and Hexadecimal Escapes Octal and hexadecimal escapes begin with \0 and \x (or \X) respectively. For example, \052 and \X2A both specify the `*' character. Escapes for null (\00 or \x0) are not valid and will generate an error message. o Shortcut Escapes for Common Character Classes \d digits 0-9 \l letters a-z and A-Z \s whitespace \t, \r, \v, \f, and space \w word characters a-z, A-Z, 0-9, and underscore, `_' `\D', `\L', `\S', and `\W' are the same as the lowercase versions except that the resulting character class is negated. o Anchors The `\B' non-word boundary anchor has been added as the logical opposite of `<' and `>' collectively. This anchor ensures that the left and right characters are either both delimiter characters or both non-delimiter characters. o Word Delimiter Escape Sequences \y Word delimiter character \Y Not a word delimiter character The `\y' token matches any single character that is one of the characters that NEdit recognizes as a word delimiter character, while the `\Y' token matches any character that is NOT a word delimiter character. Note: these are not anchors and DO consume one character of input. o Quantifiers + Minimal (lazy) Matching Quantifiers *? Match zero or more +? Match one at least one ?? Match zero or one These quantifiers match only what is absolutely necessary to achieve a match. + Counting (or Brace) Quantifier {min,max} Match from `min' to `max' times the previous regular expression atom. If `min' is omitted, it is assumed to be zero. If `max' is omitted, it is assumed to be infinity. Whether specified or assumed, `min' must be less than or equal to `max'. If both are omitted, then the construct is the same as `*'. Note that `{,}' and `{}' are both valid brace constructs. A single number appearing without a comma, e.g. `{3}' is short for the `{min,min}' construct, or to match exactly `min' number of times. o Non-Capturing Parentheses Non-Capturing Parentheses are of the form `(?:)' and facilitate grouping only and do not incur the overhead of normal capturing parentheses. o Positive Look-Ahead Positive look-ahead constructs are of the form `(?=)' and implement a zero width assertion of the enclosed regular expression. In other words, a match of the regular expression contained in the positive look-ahead construct is attempted. If it succeeds, control is passed to the next regular expression atom, but the text that was consumed by the positive look-ahead is first unmatched (backtracked) to the place in the text where the positive look-ahead was first encountered. o Negative Look-Ahead Negative look-ahead takes the form `(?!)' and is exactly the same as positive look-ahead except that the enclosed regular expression must NOT match. o Case Sensitivity (?i) Case insensitive; `AbcD' and `aBCd' are equivalent. (?I) Case sensitive; `AbcD' and `aBCd' are different. Regular expressions are case sensitive by default, i.e `(?I)' is assumed. All regular expression meta characters respond appropriately to case insensitivity including character classes and back-references. o Matching Newlines (?n) `.', `[^...]', `\s', `\S' will match newlines (?N) `.', `[^...]', `\s', `\S' do not match newlines `(?N)' is the default behavior. o Comments Comments are of the form `(?#)' and can be inserted anywhere and have no effect on the execution of the regular expression. o Notes on New Parenthetical Constructs Except for plain parentheses, none of the parenthetical constructs capture text. If that is desired, the construct must be wrapped with capturing parentheses, e.g. `((?i Repeat crashes on some systems. - Mouse state can get "stuck" on Alpha-based systems. - Combination of auto-wrap, auto-indent, and unbreakable lines extending the width of the window, caused nedit to unnecessarily insert blank lines. - Incorrect case-insensitive comparison in character sets > 128 bits. - in by-word drag-selection (double click then drag) when begun in the middle of a whitespace selection, anchor would revert to original cursor position rather than maintaining the entire whitespace block. - Language mode names containing spaces could not be used in language sensitive user-defined menu items. - New windows did not always see existing learn/replay sequence, recorded before the window was created. - Possible crash in search_string and search_window macros, when used with long search strings. - Possible crash in get_selection("any") macro. - Under Solaris, crashes on window opening, file dialog, and language mode selection, when user-defined sub-menus were used. - Filenames containing spaces could cause the .neditdb file to become unreadable. - Escape key could not be used to cancel file-selection dialogs when the file list had keyboard focus (which it almost always does). New Features in 5.0.1: - Repeat-over-range, and repeat-to-end capability for repeating last command and learn/replay sequence. - Import capability for loading macro/shell menu commands, highlight patterns, and style sets created by other users. - New macro language routines: string_to_clipboard, clipboard_to_string, toupper, tolower, variables: $em_tab_dist. - Additional default highlight patterns for sh and X resources. - Sorted Open Previous menu. - Numerous improvements to default highlighting patterns and smart indent macros. Bug Fixes in 5.0.1: - Various crashes on Motif 2.0 (Linux and FreeBSD) systems, usually associated with opening files and changing language modes. Usually, but not necessarily, following changes to user-defined menu items. - Background menu activation during drag operation could leave drag unfinished, cause undo to malfunction, and eventually lead to a crash (which was easy to trigger accidentally when the middle button is emulated with mouse-chords on a two button mouse). - X11R6 clients talking to X11R5 servers could crash on font dialog. - Rapid repetition of long macros (such as binding to key and using keyboard repeat) could cause crash. - Several commands which put up dialogs were vulnerable to timing windows where repeating the command could cause a crash. - Calling macro close() routine could cause crash if used to close the window in which the macro was executing. - Using load_macro_file() as an "include" statement in macro files could cause hang. - Artifacts when using non-matching highlight fonts, and making certain types of changes which change the fonts used to display other (not the line being modified) lines in the file. - Auto-newline wrap in overtype mode could duplicate part of wrapped text. - Lower panes in split window mode allowed modification to read-only windows. - Several minor dialog and window focus related problems for explicit (click to focus) users. - Paste Column ignored existing selection. - After copying and re-naming language mode information, highlight patterns and smart indent macros remained attached to the re-named pattern instead of the original. - Trailing newlines should not have been prohibited in Open Selected. - Help for creating smart indent macros was missing. New Features in 5.0 - Completed macro extension language (Simple C/awk-like syntax, safe, fully interruptable) - Syntax highlighting. Built-in patterns for C, C++, Java, Fortran, Pascal, Ada, Perl, Python, Tcl, Awk, Csh, HTML, LaTeX, VHDL, Verilog, and more. - Programmable Smart indent. (Experimentally, at least. There are only macros for C and C++, and they may not fit everyone's programming style.) - Language-sensitive preferences - Continuous wrap mode (long line wrapping), in addition to existing automatic-newline wrapping - User-defined menus can be hierarchical and language-sensitive. - Configurable right-button pop up menu - Pan-scrolling - Searchable on-line help - Word boundary matching (<>) in regular expressions - Repeat command - More dialogs have up-arrow recall - White-space selection via double-click Bug Fixes and Enhancements to Existing Features in 5.0 - No more limits on editing files containing ascii nul characters - Fill Paragraph command handles leading indents - Select to mark - Better directory defaulting in Open Selected and shell commands - Open Selected processes tilde (~) and wildcards - Goto Mark centers scroll position better - Multiple shell commands can be run simultaneously - Shell command execution doesn't block server command processing - Emulated-tab deletion treats auto-indent as emulated tabs - Auto-wrapping of pasted text is optional (off by default) - Notice that default preferences have changed and ask about saving on exit - Selections remain selected after shell command and filter execution - Wrap margin and emulated tab distance preferences are properly transferred to new panes in split window mode nedit-5.6.orig/Xlt/0000755000175000017500000000000011107644406012664 5ustar paulpaulnedit-5.6.orig/Xlt/BubbleButton.c0000644000175000017500000003631610343604517015430 0ustar paulpaul/** * * $Id: BubbleButton.c,v 1.9 2005/12/01 14:31:43 tringali Exp $ * * Copyright (C) 1996 Free Software Foundation, Inc. * Copyright © 1999-2001 by the LessTif developers. * * This file is part of the GNU LessTif Extension Library. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Library General Public * License as published by the Free Software Foundation; either * version 2 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The XML source is processed using James Clark's (http://www.jclark.com/) XSLT processor XT and XML parser XP. The XSL stylesheet used to generate the HTML version is here (faq.xsl). The text version is generated in three steps: first, an XSL stylesheet (faq-txt.xsl) is used to generate a simple HTML. Then, a second XSL stylesheet (faq-txt-pass2.xsl) transforms the HTML into plain text. An awk script (faq-txt.awk) then performs the word wrapping.

See "faq.dtd" for a rigourous definition; a simple overview is given here, to help in making quick additions and modifications. The FAQ is composed of two parts : a and a . The contains the title (in our case, "NEdit Frequently Asked Questions"), the list of , a which gets displayed ahead of all questions, a section showing how to download the FAQ () and other, less important stuff. The part is composed of many FAQ
s. A section has a title and groups several FAQ entries. A particular section exists, called , which contains the description of the FAQ itself. A section is generally composed of several "Question 'N' Answer" entries (). A contains a question () and the answer to that question (). An identifier must be given to each , via the attribute "id". A longer version of the question may be specified via as another element of ; in this case, the is displayed in a table of questions, while the longer and more complete version, , is displayed along with the answer. The and elements contain text paragraphs. The doesn't contain paragraphs and behaves like a single paragraph itself. A text paragraph is indicated by one of the elements

,

,
    ,
      and 
       (which, in the DTD, are collectively referred to as
%paragraph-styles;).

   The 
       denotes a basic paragraph and contains text.

   The 
       indicates an indent, and it contains other paragraphs
   inside. A nested 
       will indent relative to the previous one.

   The 
         and 
           indicate respectively an unnumbered and a numbered
   list. Both 
             and 
               contain one or many 
            1.  elements. A 
            2. 
   element contains text.

   The 
               indicates a preformatted piece of text, which will be output
   with no further modifications.

Paragraphs of type 
               and 
            3. , as well as  and a few other elements of
the , contain text. Text is composed of free text and style elements.
The style elements are the following :

    indicates an e-mail address.
   
    indicates an image. It has a required attribute "src" which must
   be a URL referring to the image, and a "alt" attribute containing
   alternate text, used for non-image-capable formats.

    indicates a web site. The text between  and  must be
   a URL.

    indicates a HTTP hyperlink. Its required attribute "href" must be
   the URL to link to. An attribute "alt" may contain alternate text.
   
    stands for emphasized text.
   
    stands for strong text.
   
    is used for terminal output and for the contents of configuration
   files.

    is used for command names, when included inline within text.
   Generally, 
               paragraphs are used for several lines of code.

The distinction between  and  and furthermore 
               is not so
clear. A clearer and better definition is needed.

NEDIT FREQUENTLY ASKED QUESTIONS
--------------------------------


Version 2001/10/01

NEdit is a popular GUI-style text editor for Unix and VMS systems. These
are answers to the most frequently asked questions to discuss@nedit.org.
This information is also available from:

    ftp://ftp.nedit.org/pub//FAQ,

and from the NEdit web page at:

    http://nedit.org.

FAQ Maintainers: Florian Xhumari (Florian.Xhumari@free.fr)



ABOUT THE NEDIT FAQ
-------------------


This FAQ is written in XML and translated to HTML using an XSL stylesheet.
The XML source is processed using James Clark's (http://www.jclark.com/)
XSLT processor XT (http://www.jclark.com/xml/xt.html) and XML parser XP
(http://www.jclark.com/xml/xp).

The XSL stylesheet used to generate the HTML version is here (faq.xsl).

The text version is generated in three steps: first, an XSL stylesheet
(faq-txt.xsl) is used to generate a simple HTML. Then, a second XSL
stylesheet (faq-txt-pass2.xsl) transforms the HTML into plain text. An awk
script (faq-txt.awk) then performs the word wrapping.

For any questions about or contributions to the FAQ, please send a mail to
the maintainers (mailto:Florian.Xhumari@free.fr).



WHERE TO GET INFORMATION
------------------------


> Where can I get information about NEdit?

The NEdit web page is at:

    http://nedit.org

and it is mirrored in Australia at:

    http://www.au.nedit.org/

The primary ftp site for NEdit is:

    ftp://ftp.nedit.org/pub

which has a mirror in The Netherlands:

    ftp://ftp.nl.nedit.org/pub/mirror/NEdit

The NEdit ftp site has executables for most Unix and VMS systems, sources,
documentation, and contributed software.

The first and easiest place to look for help with NEdit is the NEdit Help
menu. The bottom item in the menu (Problems/Bugs) has answers to the most
commonly asked questions about NEdit, which are not duplicated here. Also
check the platform specific information in the README file packaged in the
NEdit distribution kits.

If you have a problem that you really can't figure out, send mail to
discuss@nedit.org, and see if anyone else might be having the same trouble.
The nedit developers also subscribe to this list, and hopefully someone
will be able to answer your question. If you are a Silicon Graphics user
and NEdit came bundled on your system, you can also contact SGI's technical
support.

> Are there any mailing lists for NEdit users?

There are two separate mailing lists for nedit users, and one for
developers. Users may post to the developer mailing list to report bugs and
communicate with the nedit developers.

The lists are:

    * discuss@nedit.org: general discussion, questions and answers among
    nedit users and developers.

    * develop@nedit.org: communication among and with nedit developers.
    Developers should also subscribe to the discuss list.

    * announce@nedit.org: a low-volume mailing list for announcing new
    versions.

Please note that only subscribers can send mail to the list.

The nedit developers subscribe to both discuss@nedit.org and
develop@nedit.org, either of which may be used for reporting bugs. If
you're not sure, or you think the report might be of interest to the
general nedit user community, send the report to discuss@nedit.org. If it's
something obvious and boring, like we misspelled "anemometer" in the
on-line help, send it to develop@nedit.org.

Please do not cross post to both lists!

In order to subscribe to a list, send mail to majordomo@nedit.org with one
or more of the following in the body of the message:

    subscribe announce
    subscribe discuss
    subscribe develop

To unsubscribe do the same with the keyword unsubscribe.

    unsubscribe announce
    unsubscribe discuss
    unsubscribe develop

After subscribing, you will receive copies of all of the email submitted to
the lists. You may submit mail to the discussion list by sending it to the
appropriate list: discuss@nedit.org, develop@nedit.org or
announce@nedit.org.

The archives of the old mailing lists (nedit_discuss@fnal_gov and
nedit_announce@fnal.gov) can be found on egroups.com:

        * http://www.egroups.com/group/nedit_discuss/

        * http://www.egroups.com/group/nedit_announce/

For more information about the mailing lists, refer to the mailing lists
section (http://nedit.org/community/mailing.shtml) in the NEdit site.

> Where can I get binaries / executables for machines other than those
> available at NEdit site?

In past versions, we separated "supported" and "unsupported" executables
and divided them between the binary and contrib directories. With more
supported systems, you're less likely to find executables in the contrib
directory, but it's worth a peek, anyhow. If you can't find anything
appropriate, you can try asking in a usenet news group appropriate to your
system. Other places to try are, the discuss@nedit.org mailing list, or
news:comp.windows.x.apps or news:comp.editors.

> What can I contribute?

If you use and enjoy NEdit, and feel like giving something back to the
NEdit user community, contact develop@nedit.org. If you have ported NEdit
to a new machine, written a useful set of macros, or would like to
contribute to an ongoing development project, we'd love to hear from you.



DIAGNOSING AND REPORTING PROBLEMS
---------------------------------


> How do I report problems I've encountered using NEdit ?

If you have a problem which is not covered in the on-line help, in this
FAQ, or in the README file specific to your system, you can report it to
discuss@nedit.org (usage questions) or, develop@nedit.org (error reports).
Note that these lists only allow members to post, and if you are not a
member, your post will probably de delayed in reaching the list.
Alternatively you can use the bug tracker on Sourceforge
(http://sourceforge.net/projects/nedit/) to report bugs and make feature
requests. Below are some suggestions for information you can provide to
help in diagnosing your problem.

Because NEdit runs on a large number of different platforms and
environments, many problems are platform-specific. It's always helpful to
know what kind of system it's being run on. Sometimes, strange behavior can
also be traced to the X server software or window manager, so you may want
to include information on these as well.

The origin of the NEdit executable is often important, particularly,
whether it came from the NEdit site (http://www.nedit.org), was built
locally, or came from some other ftp server or freeware distribution CD.
Despite the fact that Motif appears on almost all Unix platforms, the Motif
libraries still vary from one machine to another. Be sure to mention
whether you're using Lesstif or Motif. As of version 5.2 a summary with
build information is present under 'Version' in the Help menu.

If you are having configuration or appearance problems, you should probably
look at the output from the command:

   appres NEdit nedit

The 'appres' command will show you the resources that NEdit actually sees
when it runs, including "stray" resources intended for other programs but
not properly qualified by the program name. It will also give you a final
objective check as to whether resource settings that you have made are
actually readable by NEdit.



BUILDING
--------


> When I build NEdit on my SunOS system, I get the fillowing undefined
> symbols:
> 
> ld: Undefined symbol
>    _memmove
>    _atexit
>    _strerror
> *** Error code 1
> make: Fatal error: Command failed for target `nedit'

Older versions of the gcc C runtime library were missing these functions.
You can either upgrade gcc, or get sources for these functions from
ftp://ftp.nedit.org/pub/contrib/misc (which someone else with your very
same problem kindly contributed).

> I'd like to build NEdit, but my system seems to be missing the Xm...
> include files and libXm.a

Xm means Motif, which is an important part of NEdit's GUI interface. Motif
is standard on commercial Unix workstations, but not on free Unix platforms
like Linux and FreeBSD. On these systems, you can now use LessTif, the GPL
clone of Motif, or purchase a copy of Motif, which is usually relatively
inexpensive, but not free. You can find a list of companies selling Motif
for Linux at:

    http://www.cen.com/mw3/#providers

As of this writing LessTif is very close to being a fully reliable and
complete replacement for Motif, so it's definitely worth trying before
shelling out any money for a commercial copy. Also remember that in most
cases, you don't really need Motif libraries to use NEdit. There are plenty
of versions available pre-built with the Motif libraries linked in
statically. If you can't find one for your system, ask around, and you may
find that someone else has already built one for you. Motif licensing
allows free distribution of statically linked binaries. Executables for
NEdit are available from
ftp://ftp.nedit.org/pub//executables.

> When I build NEdit, I get the yacc error:
> 
>   conflicts: 36 shift/reduce

That's normal. NEdit's macro language has a very conflicted grammar, but
the conflicts all resolve themselves correctly. The conflicts stem from
allowing awk-style no-operator concatenation of strings.

Several of the Linux distributions began including LessTif (a free version
of the Motif GUI library) before it was really ready for general use
(particularly for something which needs to be as reliable as a text
editor). If you have a version of Lesstif prior to 0.92.26, you have to
upgrade it, before it will support NEdit reliably. To get the newest
version, go to http://lesstif.org. Alternatively, you can get pre-built,
statically linked, executables from
ftp://ftp.nedit.org/pub//executables.

Not if you are using the glibc. The algorithm of mkstemp(3) consists of two
parts: the first part is the one used in tmpnam(3) -- this is what NEdit
accomplishes by calling tmpnam(3); the second part is done directly in
NEdit.

CUSTOMIZATION
-------------


> I can't get the delete key to remap to a forward delete. I have re-bound it
> in my .Xdefaults file, and that doesn't help.

In your .Xdefaults file, add:

    nedit.remapDeleteKey: False

This is now the default, so you likely have an old resource file sitting
around somewhere with this setting. When remapDeleteKey is True), NEdit
forcibly maps the delete to backspace. This can be used when the X server
and the client machine have different expectations about whether the key in
the backspace position on the keyboard is a backspace key or a delete key.
It also saves users in very heterogeneous environments from having to
re-map keys on nearly every system they use just to be able to backspace.

> My X resource settings don't work.

It's harder to explain how to specify X resources than you might expect,
since how they are set is often configured by your local system manager.
They are either automatically attached to the server (your screen) by an X
startup or login script, or they are left unspecified, and read from the
.Xdefaults file whenever you run an X application. If they are attached to
the server, you should find out the "normal" method for setting them on
your system. If it's not the .Xdefaults file, then it is usually a file
called .Xresources (also in your home directory). To make a change, you
have to either run xrdb, or re-invoke the startup script that originally
attached them, usually by exiting and re-starting X, or logging out and
back in to your X session.

Since setting resources is tricky, it's usually better to start with
something simple, like:

    nedit*foreground:green

Then, once you have that working, try the more subtle or difficult ones.
You can also use the appres command to find out what resources nedit
actually sees ('appres NEdit nedit').

> I am setting some X defaults in my $HOME/.nedit file but some of them don't
> work.

The .nedit file holds the NEdit Preferences menu options and is
automatically overwritten whenever you select "Save Defaults". You really
shouldn't put X resource settings there. Also, as you may have discovered,
resources other than Preferences resources don't always work from there.

How you set X resources depends on local system conventions. You usually
put them in the .Xdefaults or .Xresources file in your home directory. You
may also need to run xrdb to install them in the server. It depends on how
your local system has been configured, so it's best to talk to the person
who configured your system. If you're not sure whether your resources are
set up correctly, the command:

    appres NEdit nedit

will tell you what settings NEdit will see when it runs.

NEdit uses the X fallback resources mechanism to provide default values for
user-settable resources. When you provide a system-wide app- defaults file,
it overrides the entire contents of the fallback resources, meaning all of
the program defaults are lost, except for those which are also represented
in the app-defaults file. To use an app-defaults file, therefore, you need
to start from a complete one which provides all of the necessary default
values. There is a complete app-defaults file in:

    ftp://ftp.nedit.org/pub/contrib/misc/nedit.app-defaults

We strongly discourage users from using system-wide app-defaults because
once you install the file, you have to keep it up to date with every new
release of the software. If you don't update it, users might not even
notice the difference, but things will be increasingly wrong with each new
release.

> Where can I get the complete list of nedit resources?

The way X is designed, there are a LOT of user settable resources in NEdit,
most of them quite useless. You can see them all using the editres tool,
which is available on most Unix systems. A more useful subset are the
application default resources, which you can look at either in the source
code (near the beginning of nedit.c, in the variable called
fallbackResources) or in the app-defaults file in:

    ftp://ftp.nedit.org/pub/contrib/misc/nedit.app-defaults

> Can I use 'ispell' with NEdit instead of the less capable Unix 'spell'

'ispell' is actually the default spell checker for NEdit on Linux systems
where 'spell' is not available. On other systems, enter the following in
the Shell Commands dialog:

  Command Input: Either
  Command Output: Same Window
  Output Replaces Input: ON
  Shell Command: cat>spellTmp; xterm -e ispell -x spellTmp; cat spellTmp; rm spellTmp

If you want to get fancy, the following puts the temporary file in the /tmp
directory, and uses $$ (the process ID of the shell) in the file name so
you don't have to worry about clashes between simultaneous ispell sessions:

  cat > /tmp/ispell.$$; xterm -title "Spell Check" -e
  ispell -S /tmp/ispell.$$; cat /tmp/ispell.$$; rm /tmp/ispell.$$

It depends on the system you are running how easy this is to do. Under
Motif 2.0, which I think is still only found on Linux and Free-BSD systems,
it's a simple resource setting:

    nedit*XmFileSelectionBox.fileFilterStyle: FILTER_HIDDEN_FILES

On other systems, unfortunately, it's a rather difficult source code
change, involving creating a replacement file searching procedure to be
spliced in to the file selection box widget.

Set the X resource nedit.stdOpenDialog to True. The field is disabled by
default to get new users accustomed to typing the file name directly in to
the list widget, which is not standard Motif behavior.

The block cursor in NEdit is used to indicate overstrike mode, but you can
turn on a resource to make the cursor thicker:

    nedit*text.heavyCursor: true

The only way to get a permanent block cursor, though is to hack the source
code. This shouldn't be too difficult, since the code for drawing a block
cursor is already there.

The only effective way I've found to control the number of items in the
highly temperamental Motif FileSelectionBox widget is through the height
resource:

    nedit*FileSelect.height: 900

The X resource line above will make the file selection box 900 pixels tall.

You can turn mnemonics off by setting them to the ascii null character, for

It's somewhat involved and hard to figure out from the documentation, but
yes you can. You have to reverse the translation table bindings for mouse
buttons 2 and 3, AND reset the bgMenuButton resource. The translation table
bindings can either be found in the source file source/text.c, or by adding
and activating a temporary translation to the text widget for dumping the
translation table itself (XtDisplayTranslations()).

What it boils down to, though, is just add the following lines to your X
resource file (.Xdefaults or .Xresources depending on your system):

  NEdit*text.Translations: #override \n\
     : secondary_or_drag_start()\n\
     Shift Ctrl Button3: \
         secondary_or_drag_adjust("rect", "copy", "overlay")\n\

Use a macro command instead to do the prompting:

There's no equivalent to the nedit*text.selectForeground resource when you
turn on syntax highlighting. You just have to choose a selection color that
is compatible with all of your highlighting colors.



FEATURES
--------


> I'm a little confused about what happend to drag and drop. I thought
> drag-N-drop was supported by the Motif library.

NEdit no longer uses the Motif text widget, so all of the functionality had
to be duplicated in the new widget. Drag and drop between windows got left
off due to time pressure of getting out the new release, but it will be
back some day.

> Why don't you integrate Max Vohlken's / Yunliang Yu's versions into the
> official release of NEdit

Many of their changes will eventually find their way in to the "official"
version, but some will not. Max has really done quite a lot of stuff. I
appreciate it, and I think it's kind of neat to have a "bleeding edge"
version of NEdit around to try out new features.

I can't just apply Max's patches to our version and release it. Some of
them break the VMS version, some interfere with existing commands that are
important to other users, and some are just customizations that I don't
particularly agree with. Mostly, I want to do a lot of testing to make sure
the changes are safe on all platforms, and I just don't have time right
now. (Mark Edel)

Update as of NEdit version 5.2RC1: The forthcoming NEdit version 5.2
contains several functionalities of Max's patches.

There is an NT version of NEdit, available at
http://nedit.org/download/win32.shtml. A mini-FAQ is also available.

X has a strict convention that there can be only one selection at a time on
the whole display. This means that some of the tricks used in PC and
Macintosh programs don't work in X. On PCs and Macs, programs can fill in
default values in text fields, and select the text that they have inserted
such that If the user types over the selection, it will automatically be
erased. Under X, there is a price to pay for making an automatic selection.
The selection must be "stolen" from some other window, maybe some other
program. If the user's intent was to paste a selection that existed before
the dialog popped up, once the automatic selection is made, they are out of
luck.

If NEdit automatically transferred the selection to the Find or Replace
dialog, it would either have to steal the selection, or users would have to
click or drag the mouse over the text to delete it before they could type
anything different. Instead, NEdit has a "Find Selection" command, as well
as various methods of pasting and copying the selection into dialog fields.
It also allows you to recall of previous search strings in the Find and
Replace dialogs via the up-arrow and down-arrow keys.

> I would like to use (multiple fonts, special symbols) in my file, but NEdit
> seems to allow just one single font.

NEdit is a plain text editor, not a word processor. Plain text files have
no font or formatting information contained in them, they are just a string
of ascii characters. While you might find a font with limited symbols and
greek letters, your troubles would just be beginning. You'd still have
trouble getting the printer to agree and print out the characters as they
appeared in NEdit. For anything involving font changes or special symbols,
you need a word processor, such as Microsoft Word, or a text formatting
program like LaTEX.

You probably want continuous wrap mode (Preferences -> Wrap -> Continuous).

Because NEdit is not a word processor, it is stuck with the limits of the
plain text format. In the default, auto-newline, wrapping mode, nedit does
wrapping by inserting newline characters. Because there is only one newline
character, NEdit can't distinguish a newline which can be "unwrapped" from
one which the user intended to be permanent. While it might be possible for
NEdit to temporarily make that distinction, for example while the cursor is
on a particular line that the user is typing, ultimately, NEdit will have
to forget this information, because there is no way to save it in the file.
Users who work in auto-newline wrap mode tend to make liberal use of the
Fill paragraph command.

In continuous wrapping mode, you can intentionally leave out the newlines
within paragraphs, and lines will be wrapped as needed to fit within the
page. When you edit in the middle of a paragraph, the text will be
continuously adjusted. However, continuous wrap mode has it's limitations
too. All paragraphs must be lined up against the right margin to take
advantage of continuous wrapping, and Unix systems have limited support for
files of that format. You may have trouble printing and viewing the files
outside of NEdit.

> NEdit scrolls too fast when I extend a selection by dragging the mouse
> outside of the window.

NEdit features proportional auto-scrolling, where the speed is controlled
by how far your mouse is beyond the edge of the window. If you want it to
scroll slower, bring the mouse back closer to the text.

Below is an example from the NEdit discussion list (from David L.
Paterline) of a "Find All" command implemented by using the selection as an
argument to the grep command:

    I set up a command to list all lines in a file which contain the
    highlighted selection as follows, using the Preferences -> Shell
    Commands menu:

        Menu Entry:           all 
        Command Input:        selection
        Command Output:       new window
        Save file before:     yes
        Shell Command:        grep -n -- "`cat -`" %

    The 'cat -' portion of the command echoes the selected text to the
    'grep -n' command, which lists the lines containing the selection with
    line numbers. The output of the command appears in a new window; I can
    then highlight a line number in the new window and use the Search ->
    Goto Selected menu in the original window to jump to the line in the
    original file.

> How can I print highlighted text on my printer as it appears in NEdit.

In the current version, that's not possible, but there are external tools
for highlighting, which are specifically designed for printing, including
a2ps, enscript, and genscript.



SERVER MODE AND NC
------------------


> I use a mailer which can invoke an external editor, but if I use nc, the
> mailer process continues and assumes the editor has finished, when in fact

nc is actually finished communicating with the NEdit server when it
returns. It's possible to create a shell command that invokes nc and then
goes to sleep, and a second script to be run from the NEdit Shell menu,
which looks for the sleeping process with a matching file name and kills
it. Try the shell scripts in:

    ftp://ftp.nedit.org/pub/contrib/misc/nc_and_wait.tar

> Isn't this a security hole?

Actually, NEdit does check who the user is. When you use the su command,
however, several Unix variants return the original user name in response to
the standard C library calls for getting a user name, rather than the name
to which you have su'd. Starting with version 5.1, a different mechanism is
used for getting this information, so you shouldn't see this problem any
more.

In your case, my guess is that you used su to become root, then started an
nedit server as root. On a system which returns the original user name,
both the new server and the nc client program think the user name is your
original user name, so the server accepts requests from both you as root
and you as you.

The security of an nedit session, depends upon the security of your X
server. Only those with access to your screen can send commands to an nedit
server, but they can also send keystrokes to any nedit, or a shell window,
etc... Anyhow, just upgrade to the latest NEdit version.



EDITING TECHNIQUES
------------------


> I'd like to select a large expanse of text without dragging all the way
> through it with the mouse.

Using the shift key with the left mouse button, you can select all of the
text between the cursor (or an existing selection) and the mouse.

    * Position the cursor at one end of the desired selection

    * Use the scroll bar to make the other end visible

    * Shift+Click with the left mouse button to select the text between the
    cursor and the mouse

Alternatively, using only keyboard navigation:

    * Position the cursor at one end of the desired selection

    * Type Alt-m and a letter to mark the position

    * Use the keyboard to go to the other end of the desired selection

    * Type Shift-Alt-g and the letter you used to mark the first end of the
    selection

> How can I select the text between two marks?

    * Go to the first mark (Goto Mark).

    * Hold the shift key while selecting Goto Mark or Alt+Shift+G to select
    the text.



BUGS
----


> The keyboard shortcuts (accelerator keys) are not working when 'Caps' or
> 'Num Lock' are switched on. Have I overlooked something obvious?

You haven't overlooked anything, it's a Motif design flaw. Netscape
painfully works around this and the Alt/Meta key reversal on Sun
workstations by internally re-implementing the Motif menu accelerator
mechanism. NEdit will likely follow suit with the release of version 5.2.

Another possibility (writes Peter Daifuku of SGI):

    There's another answer which unfortunately isn't widespread as yet. For
    an X11R6.3 X server supporting the XKB extension, there is a mechanism
    to ignore the NumLock and CapsLock key as modifiers. The file
    /usr/lib/X11/xkb/X0-config.keyboard should contain the string
    IgnoreLockMods=NumLock+Lock . For systems with multiple displays,
    display 1 would be controlled by the file X1-config.keyboard, etc.

    On SGI systems, this mechanism is support on IRIX 6.2 with X server
    patch 1574 or later, on IRIX 6.3 and IRIX 6.4 and all later releases.

> Sometimes NEdit inserts  instead of saving the file when I type ^S.
> Other keyboard shortcuts (accelerator keys) don't work either.
You have probably NumLock or CapsLock ON. See the answer to this (#N900)
question.
> I use the numeric keypad really often, so I keep NumLock on. But NEdit
> shortcuts don't work when NumLock is on.

The bug is not in NEdit, but in Motif. This is fixed as of NEdit 5.2, but
that might not help you much. Older versions have the same problem.

Here's how you tell X to interpret the keypad keys as numbers without
turning NumLock on. Create a file .Xmodmap in your home directory, and put
the following lines in it:

  keycode  79 = KP_7
  keycode  80 = KP_8
  keycode  81 = KP_9
  keycode  83 = KP_4
  keycode  84 = KP_5
  keycode  85 = KP_6
  keycode  87 = KP_1
  keycode  88 = KP_2
  keycode  89 = KP_3
  keycode  90 = KP_0
  keycode  91 = KP_Decimal

Then make sure the script that starts your X session parses this file with
the command:

  xmodmap -merge ~/.Xmodmap

This script can be ~/.xinitrc (called by startx) or something like Xsession
if you use xdm/kdm/gdm. Then again, it might be an entirely different
script on some systems.

Then turn off numlock, and just continue using the keypad. The only thing
is, you loose the alternate set of functions (cursor/home/pgdown/etc).

> NEdit crashes I try to paste text in to a text field in a dialog (like Find
> or Replace) on my SunOS system.

On many SunOS systems, you have to set up an nls directory before various
inter-client communication features of Motif will function properly. Before
NEdit 4.0 this wasn't much of a problem, because users couldn't cut and
paste at all, and Motif would sometimes print a warning about not finding
an nls directory, so most users figured it out right away. But with 4.0,
everything seems to be working fine, except when someone tries to move text
in or out of a dialog field, then blamo.

There are instructions in README.sun in
ftp://ftp.nedit.org/pub/ NEdit crashes frequently, particularly on window closing.

There is an obsolete resource in Motif called defaultFontList, which does
nothing but cause random crashing. I don't know why NEdit users keep
popping up with this resource set, maybe it looks enticing when you look at
widget resources with editres. Anyhow, setting it to anything, whether it
be a valid font or just garbage, causes random crashing in both Motif 1.2
and 2.0, so just don't set it.

> NEdit sometimes crashes when I execute a shell command menu item I just
> added.

Check the "Command Input" setting, in the Preferences->Shell Commands
dialog for that menu item. If the shell command being executed does not
take input, but "Command Input" is set to "selection" or "window", NEdit
tries to write the input anyhow, and fails. Set "Command Input" to "none"
to prevent this possibility. This is fixed in version 5.1 and later.

> When NEdit starts up, I get errors:
> 
>    Cannot allocate colormap entry for "#b3b3b3"
>    Cannot allocate colormap entry for "#e5e5e5"

Most X displays are set up to operate in a mode which allocates 8 bits of
video memory per-pixel, and requires a color mapping table to translate
pixel values to screen colors. With just 8 bits there are only 256 possible
colors, and programs must either allocate and share these pixel values, or
swap in their own colormap and make all other windows flash to strange
colors while their window is focused. Some programs, Netscape in
particular, are bad neighbors in this environment and snarf up every free
entry in the shared colormap, such that every program that runs after them
gets the errors you're asking about.

The solution is either to start Netscape last, after all other applications
that you might want to run, or better, tell Netscape how many colors it is
allowed to allocate. Fortunately, you can do this with a resource setting:

    Netscape*maxImageColors: 80

> Sometimes when I use regular expression replacement inside of a rectangular
> selection, NEdit fails to match text which does legally match the

The problem with REs and rectangular selections is that matching is bounded
by the rectangular selection, but text outside of the selection is still
fed to the matching routines, so ^, $, don't refer to the edges of the
selection, they still refer to the beginning and ending of the line, and
some legal matches are excluded because they continue outside of the
selection are thereby excluded, or are shadowed by matches which begin or
end outside of the selection.

You probably have printing commands in your shell startup file (.cshrc, or
equivalent). These should either be skipped in non-interactive mode, or
moved to your .login file. You can often see the problem outside of nedit
by typing:

    csh -c ls

Error messages from stty are a result of it being executed from a process
which isn't attached to a terminal. You can safely move stty statements and
most other interactive commands to your .login file (calling stty from a
.cshrc file is redundant because the terminal device doesn't change for
each sub-shell). If you can't remove interactive commands, you should skip
around them in non-interactive shells, I think the usual method is to put
them at the end, preceded by something like:

    if ($?prompt == 0) exit

The manual entry on csh has more information on this.

It's a bug in the shared Motif library. Depending on your system, the patch
is one of ID# 103461-07, # 102226-19, or # 103186-21. If you can't patch
your system, you can set the resource:

    nedit*XmFileSelectionBox.pathMode:  XmPATH_MODE_RELATIVE

This will stop the dialog from displaying the path component of file names.
Another possible workaround is to use the nedit_sunos executable (from
ftp://ftp.nedit.org/pub/), which is statically linked with a good Motif.

In some versions of S.u.S.E. Linux, there's apparently something wrong with
their builds of NEdit and other Motif apps. I've been told you can make
nedit work by seting the environment variable LD_PRELOAD to
/lib/libBrokenLocale.so.1 before launching it. You can also use the
statically linked version of NEdit for Linux from ftp://ftp.nedit.org/pub/

> NEdit seems to be running very slowly on my Solaris 2.6 system.

If you're running NEdit on a Solaris 2.6 system and experiencing
performance problems (windows come up slowly), the patch for Sun's shared
Motif library is ID# 105284-04. Installing the patch alone will improve the
performance dramatically. The patch also enables a resource,
*XmMenuReduceGrabs. Setting this to True will eliminate the delay
completely.

> I can't seem to enter accented characters on my system.

This should be working properly on most systems as of NEdit 5.1 or later.
If it's not, try re-building NEdit with -DNO_XMIM. If it still doesn't
work, send mail to develop@nedit.org

There is another program called 'nc' which is installed on some systems. In
this case, 'nc' is for 'netcat', some kind of network diagnostic tool. You
can safely rename NEdit's 'nc' to something else (we recommend ncl), or put
it first in your path before 'netcat'.

Several users have reported this problem. Most of them were using S.u.S.E.
Linux . A few others had different distributions, but always European. The
problem appears to be related to how Motif searches for named pixmaps and
bitmaps. My guess is that on some systems, this search encounters a match
with a bad pixmap file, or tries to load something which is not a pixmap at
all. One solution was to set the environment variable XBMLANGPATH to a
random directory. For example:

  XBMLANGPATH=.
  export XBMLANGPATH

The solution on S.u.S.E Linux systems was to remove an unnecessary line in
the global /etc/profile (provided by S.u.S.E.):

  export XAPPLRESDIR=
      "$XAPPLRESDIR:/var/X11R6/app-defaults:/usr/X11R6/lib/X11/app-defaults"

Another user who had the problem reported that the root cause appeared to
be insufficient read permissions on some xm_* (e.g. xm_warning) pixmaps in
"/usr/X11R6/include/X11/bitmaps". (Could someone else confirm this?)

It's a bug/feature of NEdit that it considers a shell command process alive
as long as any of it's file descriptors remain open. Forked processes
generally copy and keep open the stdout and stderr descriptors from their
parent process, so you have to add '>& /dev/null' to your shell command, so
it reads:

    mctags >& /dev/null &

Until version 5.0, NEdit had no way of even knowing what language you were
operating in when making the flash/match decision, so it simply counted
opening and closing instances, disregarding language syntax context
(strings, comments, etc.) completely. Now that the feature is more possible
to implement, it may be included in a future version, but I'm not entirely
sure how best to do it yet.

How large a file you can edit with NEdit depends on how much swap space +
RAM you have, since it loads your file into virtual memory and occasionally
does a full copy of that memory space. NEdit can handle a 100MB file
reasonably well if you increase your swap space, but I don't know how far
beyond that it can go. To work with a 100MB file, you must have at least
200MB of virtual memory available. Many Unix systems can be set up to
temporarily increase swap space by creating a temporary swap file.

You have an out-of-date app-defaults file. We strongly recommend not using
such files for this exact reason. When you use an app-defaults file, it
replaces ALL of the program defaults. If you do install an app-defaults
file, it is your responsibility to keep it up to date with each new release
of the executable. Otherwise, as you have observed, certain features will
degrade with each release, as the app-defaults file and the executable get
further and further out of sync with eachother.

XVision is grabbing the selection immediately, as soon as it is made, not
allowing applications to own it. This behavior is completely wrong, and I
have no idea what they might have been thinking when they implemented it.
It may be possible to turn it off, ask their technical support people if
they're not already out of business.

A remnant of pre-regular-expression, pre-macro-language NEdit, is that
replacement strings are limited to 511 bytes. This is high on the list to
fix in a future upgrade.

> NEdit is slow and pages continuously on my 8MB Linux system

On most Unix workstations, 8MB of RAM is actually insufficient to run X and
Motif properly. Some Linux users get by with it and Linux itself seems to
be quite memory efficient, but you really should have 12 or 16 if you're
going to be using X much. NEdit would not be my first choice in editors on
an 8MB system.

> Some of the special keys on my keyboard don't do what I expect.

X systems are rife with this kind of problem because are just too many
levels of re-settable bindings between the keyboard and the application
program that reads it. Sun systems are the worst offenders, combining poor
Motif support with a variety of strange keyboard arrangements.

To diagnose these problems, you have to look at all three levels of key
binding that affect Motif programs.

At the bottom level are the modifier map and keymap table, where hardware
key codes are bound to X keysyms. You can see the bindings on this level
with the xmodmap program (see man xmodmap). A useful tool in debugging the
xmodmap level is a program like xev, which can show you the keysyms it
receives.

The next level up from that is the motif virtual binding level (see man
VirtualBindings). You can (usually) view the bindings at this level by
looking at the value of the root window property: _MOTIF_DEFAULT_BINDINGS,
using the xprop -root command, however what you see is not necessarily what
you'll get. The defaults for these bindings are determined by an
unbelievably complicated process involving not just the application in
question, but Motif applications which have run before it attached to the
same server. This process is described in detail in the VirtualBindings
manual page (which is often not available on systems where the bindings are
messed up). While it's usually better to attack system configuration
problems at the source, this one is so contorted that you're better off
with a patch. Luckily, the default Motif virtual bindings can be overridden
by an application resource called defaultVirtualBindings. If you think the
problem is at the Motif virtual binding level, define a
defaultVirtualBindings resource in your .Xresources or .Xdefaults file,
using the example below as a template, replacing the keysym names (to the
right of the colon) with the keysyms shown by xev when you press the
desired key:

   !
   ! Motif Virtual Key Bindings
   !
   nedit*defaultVirtualBindings: \
        osfActivate     :               KP_Enter\n\
        osfCancel       :               Escape\n\
        osfHelp         :               Help\n\
        osfMenu         :               F4\n\
        osfMenuBar      :               F10\n\
        osfLeft         :               Left\n\
        osfUp           :               Up\n\
        osfRight        :               Right\n\
        osfDown         :               Down\n\
        osfBeginLine    :               Home\n\
        osfEndLine      :               End\n\
        osfPageUp       :               Prior\n\
        osfPageDown     :               Next\n\
        osfBackSpace    :               BackSpace\n\
        osfDelete       :               Delete\n\
        osfInsert       :               Insert\n\
        osfUndo         :               F14\n\
        osfAddMode      :Shift          F8\n\
        osfCopy         :               F16\n\
        osfCut          :               F20\n\
        osfPaste        :               F18\n

If NEdit is having binding problems, chances are that other Motif-based
programs are also having trouble. Removing the "nedit" from the resource
name above (just *defaultVirtualBindings), will apply it to the other Motif
programs that you run as well.

The top level bindings in the key binding hierarchy, are the X toolkit
translation tables (see the NEdit Help section called X Resources). To show
the translations in use, you can add a binding which dumps the table
itself:

    nedit*text.Translations: #override \
        Altt: XtDisplayTranslations()\n

Typing Alt+T will then display the contents of the translation table to
stdout (the terminal from which you started NEdit). If you have the NEdit
source, you can also look at the default bindings in the module text.c.

Sometimes, even if you don't understand the problem, you can patch around
it by supplying translations for the keysyms that NEdit actually sees,
binding them to the action routines that you want activated when you press
that key.

It was considered dangerous to have a commonly used key potentially execute
arbitrary shell commands unintentionally (think rm -Rf). Therefore the
shortcut was changed to Ctrl+KP Enter. In case you want the old binding
back, you can add the following lines to your .Xdefaults or .Xresources
file:

   nedit*shellMenu.executeCommandLine.accelerator: KP_Enter",
   nedit*shellMenu.executeCommandLine.acceleratorText: KP Enter",

Where to get information




Where can I get information about NEdit?




              The NEdit web page is at:
              


              http://nedit.org
              


              and it is mirrored in Australia at:
              


              http://www.au.nedit.org/
              



              The primary ftp site for NEdit is:
              


              ftp://ftp.nedit.org/pub
              


              which has a mirror in The Netherlands:
              


              ftp://ftp.nl.nedit.org/pub/mirror/NEdit
              



              The NEdit ftp site has executables for most Unix and VMS
systems, sources, documentation, and contributed software.
              


              The first and easiest place to look for help with NEdit is the NEdit Help
menu.  The bottom item in the menu (Problems/Bugs) has answers to the most
commonly asked questions about NEdit, which are not duplicated here.  Also
check the platform specific information in the README file packaged in
the NEdit distribution kits.
              


              If you have a problem that you really can't figure out, send mail
to discuss@nedit.org, and see if anyone else might be
having the same trouble.  The nedit developers also subscribe to this
list, and hopefully someone will be able to answer your question.
If you are a Silicon Graphics user and NEdit
came bundled on your system, you can also contact SGI's technical support.
              

              
              



Are there any mailing lists for NEdit users?




              There are two separate mailing lists for nedit users, and one for
developers. Users may post to the developer mailing list to report
bugs and communicate with the nedit developers.
              



              The lists are:

answers among nedit users and developers.
                • 


              • develop@nedit.org: communication among and with
nedit developers. Developers should also subscribe to the discuss
list.
                • 


              • announce@nedit.org: a low-volume mailing list for
announcing new versions.
                • 


              


              Please note that only subscribers can send mail to the list. 
              


              The nedit developers subscribe to both
discuss@nedit.org and develop@nedit.org,
either of which may be used for reporting bugs. If you're not sure,
or you think the report might be of interest to the general nedit
user community, send the report to discuss@nedit.org. If it's
something obvious and boring, like we misspelled "anemometer" in the
on-line help, send it to develop@nedit.org.
              


              Please do not cross post to both lists!
              




              In order to subscribe to a list, send mail to majordomo@nedit.org
with one or more of the following in the body of the message:

Where can I get binaries / executables for machines other than
those available at NEdit site?

              


              In past versions, we separated "supported" and "unsupported" executables
and divided them between the binary and contrib directories.  With more
supported systems, you're less likely to find executables in the contrib
directory, but it's worth a peek, anyhow.  If you can't find anything
appropriate, you can try asking in a usenet news group appropriate to your
system.  Other places to try are, the
discuss@nedit.org mailing list, or
news:comp.windows.x.apps
or news:comp.editors.
              

              




What can I contribute?




              If you use and enjoy NEdit, and feel like giving something
back to the NEdit user community, contact
develop@nedit.org. If you have ported NEdit to a new
machine, written a useful set of macros, or would like to contribute
to an ongoing development project, we'd love to hear from you.
              

              
              



              








              

Diagnosing and reporting problems


How do I report problems I've encountered using NEdit ?




              If you have a problem which is not covered in the on-line help, in this FAQ,
or in the README file specific to your system, you can report it to
discuss@nedit.org (usage questions) or,
develop@nedit.org (error reports). Note that these lists only
allow members to post, and if you are not a member, your post will probably de
delayed in reaching the list. Alternatively you can use the bug tracker on
Sourceforge (http://sourceforge.net/projects/nedit/) to report
bugs and make feature requests. Below are some suggestions for information you
can provide to help in diagnosing your problem.
              


              Because NEdit runs on a large number of different platforms and environments,
many problems are platform-specific.  It's always helpful to know what kind of
system it's being run on.  Sometimes, strange behavior can also be traced to
the X server software or window manager, so you may want to include information
on these as well.
              


              The origin of the NEdit executable is often important, particularly, whether
it came from the NEdit site (http://www.nedit.org), was built
locally, or came from some other ftp server or freeware distribution CD. 
Despite the fact that Motif appears on almost all Unix platforms, the Motif
libraries still vary from one machine to another.  Be sure to mention whether
you're using Lesstif or Motif. As of version 5.2 a summary with build
information is present under 'Version' in the Help menu.
              



              If you are having configuration or appearance problems, you should probably
look at the output from the command:
              


                 appres NEdit nedit

              


              The appres command will show you the resources that
NEdit actually sees when it runs, including "stray" resources
intended for other programs but not properly qualified by the program
name. It will also give you a final objective check as to whether
resource settings that you have made are actually readable by
NEdit.

ftp://ftp.nedit.org/pub/contrib/misc
(which someone else with your very same problem kindly contributed).
              

              
              


I'd like to build NEdit, but my system seems to be missing the Xm...
include files and libXm.a




              Xm means Motif, which is an important part of NEdit's GUI interface.  Motif
is standard on commercial Unix workstations, but not on free Unix platforms
like Linux and FreeBSD.  On these systems, you can now use LessTif, the
GPL clone of Motif, or purchase a copy of Motif, which is usually relatively
inexpensive, but not free.  You can find a list of companies selling Motif
for Linux at:
              


              

              
    http://www.cen.com/mw3/#providers

              

              


              As of this writing LessTif is very close to being a fully reliable and
complete replacement for Motif, so it's definitely worth trying before
shelling out any money for a commercial copy.  Also remember that in most
cases, you don't really need Motif libraries to use NEdit.  There
are plenty of versions available pre-built with the Motif libraries
linked in statically.  If you can't find one for your system, ask around,
and you may find that someone else has already built one for you.  Motif
licensing allows free distribution of statically linked binaries.
Executables for NEdit are available from
ftp://ftp.nedit.org/pub/<current-version>/executables.
              

              
              


When I build NEdit, I get the yacc error: conflicts: 36 shift/reduce



              When I build NEdit, I get the yacc error:
              

                conflicts: 36 shift/reduce

              
              




              That's normal.  NEdit's macro language has a very conflicted grammar, but the
conflicts all resolve themselves correctly.  The conflicts stem from allowing
awk-style no-operator concatenation of strings.
              

              
              


I built NEdit on my Linux system, and it's full of bugs.  What a horrible
editor!




              Several of the Linux distributions began including LessTif (a free
version of the Motif GUI library) before it was really ready for
general use (particularly for something which needs to be as reliable
as a text editor).  If you have a version of Lesstif prior to 0.92.26,
you have to upgrade it, before it will support NEdit reliably.  To get
the newest version, go to http://lesstif.org.  Alternatively,
you can get pre-built, statically linked, executables from
ftp://ftp.nedit.org/pub/<current-version>/executables.

 While compiling NEdit on Linux, I get a warning about
tmpnam being dangerous. 



              While compiling NEdit on Linux, I get the following warning:
              


                  file.o: In function `PrintString':
    file.o(.text+0x17b7): the use of `tmpnam' is dangerous, better use `mkstemp'

              


              Is NEdit insecure?
              

              




              Not if you are using the glibc. The algorithm of mkstemp(3) consists of
two parts: the first part is the one used in tmpnam(3) -- this is what
NEdit accomplishes by calling tmpnam(3); the second part is done directly
in NEdit.

NEdit fails to build on Linux, with messages about `XpGetDocumentData'



              NEdit fails to build on Linux, with messages
              


                 undefined reference to `XpGetDocumentData'
   undefined reference to `XpGetPageDimensions'
   ...

              

              




              Edit makefiles/Makefile.Linux, and add '-lXp' to the line starting with
'LIB', right before '-lXext'. At this time we are not sure whether libXp
(the X print library) is installed on all Linux systems.
              

              

              


              












              

Customization


I can't get the delete key to remap to a forward delete


              I can't get the delete key to remap to a forward delete. I
have re-bound it in my .Xdefaults file, and that doesn't
help.
              




              In your .Xdefaults file, add:
              


              
    
              nedit.remapDeleteKey: False
              

              


              This is now the default, so you likely have an old resource file
sitting around somewhere with this setting.  When remapDeleteKey is
True), NEdit forcibly maps the delete to
backspace.  This can be used when the X server and the client
machine have different expectations about whether the key in the
backspace position on the keyboard is a backspace key or a delete
key.  It also saves users in very heterogeneous environments
from having to re-map keys on nearly every system they use
just to be able to backspace.
              

              
              


My X resource settings don't work.




              It's harder to explain how to specify X resources than you might
expect, since how they are set is often configured by your local
system manager. They are either automatically attached to the server
(your screen) by an X startup or login script, or they are left
unspecified, and read from the .Xdefaults file whenever you run an X
application.  If they are attached to the server, you should find out
the "normal" method for setting them on your system. If it's not the
.Xdefaults file, then it is usually a file called .Xresources (also
in your home directory). To make a change, you have to either run
xrdb, or re-invoke the startup script that originally attached them,
usually by exiting and re-starting X, or logging out and back in to
your X session.
              


              Since setting resources is tricky, it's usually better to start with
something simple, like:
              


              

              nedit*foreground:green
              

              


              Then, once you have that working, try the more subtle or difficult ones.
You can also use the appres command to find out what resources nedit
actually sees (appres NEdit nedit).
              

              
              


I am setting some X defaults in my $HOME/.nedit file but some of
them don't work.




              The .nedit file holds the NEdit Preferences menu options and is
automatically overwritten whenever you select "Save Defaults".  You
really shouldn't put X resource settings there.  Also, as you may have
discovered, resources other than Preferences resources don't always
work from there.
              


              How you set X resources depends on local system conventions.  You
usually put them in the .Xdefaults or .Xresources file in your home
directory.  You may also need to run xrdb to install them in the server.
It depends on how your local system has been configured, so it's best
to talk to the person who configured your system.  If you're not sure
whether your resources are set up correctly, the command:
              


                  appres NEdit nedit

              


              will tell you what settings NEdit will see when it runs.
              

              
              



If I install an "app-defaults" file for NEdit (empty too), all default
shortcuts are reset



              If I install an "app-defaults" file for NEdit (empty too), all default
shortcuts are reset (only "Alt+B" and "Alt+Z" works). Without that file
all works fine. Now, how can I customize nedit with this problem ? Or,
how can I get a copy of all default shortcuts to add on my NEdit
"app-defaults" file ?
              
              




              NEdit uses the X fallback resources mechanism to provide default values
for user-settable resources.  When you provide a system-wide app-
defaults file, it overrides the entire contents of the fallback
resources, meaning all of the program defaults are lost, except for
those which are also represented in the app-defaults file.  To use an
app-defaults file, therefore, you need to start from a complete one
which provides all of the necessary default values.  There is a complete
app-defaults file in:
              


              

              ftp://ftp.nedit.org/pub/contrib/misc/nedit.app-defaults
              

              


              We strongly discourage users from using system-wide app-defaults because
once you install the file, you have to keep it up to date with every new
release of the software.  If you don't update it, users might not even
notice the difference, but things will be increasingly wrong with each
new release.
              

              
              


Where can I get the complete list of nedit resources?




              The way X is designed, there are a LOT of user settable resources in NEdit,
most of them quite useless.  You can see them all using the editres tool,
which is available on most Unix systems.  A more useful subset are the
application default resources, which you can look at either in the source code
(near the beginning of nedit.c, in the variable called fallbackResources) or
in the app-defaults file in:
              


              

              ftp://ftp.nedit.org/pub/contrib/misc/nedit.app-defaults
              

              

              
              

 Can I use ispell with NEdit instead of the less
capable Unix spell command?




              ispell is actually the default spell checker for NEdit on Linux systems where
spell is not available. On other systems, enter the following in the Shell
Commands dialog:
              


                Command Input: Either
  Command Output: Same Window
  Output Replaces Input: ON
  Shell Command: cat>spellTmp; xterm -e ispell -x spellTmp; cat spellTmp; rm spellTmp

              


              If you want to get fancy, the following puts the temporary file in the /tmp
directory, and uses $$ (the process ID of the shell) in the file name so you
don't have to worry about clashes between simultaneous ispell sessions:
              


                cat > /tmp/ispell.$$; xterm -title "Spell Check" -e
  ispell -S /tmp/ispell.$$; cat /tmp/ispell.$$; rm /tmp/ispell.$$

              

              
              


How can the display of hidden (eg .login) files in dialog boxes be
suppressed



              How can the display of hidden (eg .login) files in dialog boxes be
suppressed?  We use nedit with for teaching programming with very naive
and inexperienced students.  The display of these in dialogs such as the
"Save as..." one encourages them to screw up important login stuff, state
files etc.
              
              




              It depends on the system you are running how easy this is to do.  Under
Motif 2.0, which I think is still only found on Linux and Free-BSD systems,
it's a simple resource setting:
              


              

              nedit*XmFileSelectionBox.fileFilterStyle: FILTER_HIDDEN_FILES
              

              


              On other systems, unfortunately, it's a rather difficult source code change,
involving creating a replacement file searching procedure to be spliced in
to the file selection box widget.
              

              
              



Why, in the 'open file' dialog, there is no text field where to
type in the file name?



              Most Motif applications allow you to type in the file name in a separate
text field (as in the 'open file' dialog).  Why doesn't NEdit?  Can
I make it do that?
              
              




              Set the X resource nedit.stdOpenDialog to True.  The field is disabled by
default to get new users accustomed to typing the file name directly in to
the list widget, which is not standard Motif behavior.
              

              
              


I would like to change NEdit's cursor from a
bar to a block



              I would like to change NEdit's cursor from a
bar to a block.  I seem to lose it sometimes in my text.
              
              




              The block cursor in NEdit is used to indicate overstrike mode, but
you can turn on a resource to make the cursor thicker:
              


              
  
              nedit*text.heavyCursor: true
              

              


              The only way to get a permanent block cursor, though is to hack the source
code.  This shouldn't be too difficult, since the code for drawing a block
cursor is already there.
              

              
              


I'd like to see more than 8 files in the file selection dialogs (Open,
Save As, etc.)



              I'd like to see more than 8 files in the file selection dialogs (Open,
Save As, Include, etc.).  I've tried to set the X-resources like
nedit*XmList.visibleItemCount: 20, but this did not work.
              
              




              The only effective way I've found to control the number of items in
the highly temperamental Motif FileSelectionBox widget is through the
height resource:
              


              

              nedit*FileSelect.height: 900
              

              


              The X resource line above will make the file selection box 900 pixels
tall.
              

              
              



I am trying to do key bindings such that, for example, Find is Alt+F rather
than Ctrl+F, but this clashes with the find menu mnemonic



              I am trying to do key bindings such that, for example, Find is Alt+F rather
than Ctrl+F.  However, this clashes with the find menu mnemonic.  I realize
that the menu mnemonics can be changed to any letter, but they are always
bound to Alt-letter.  I would like to just remove all menu mneumonics.  Is
there any way to do this in an .Xdefaults file?
              
              




              You can turn mnemonics off by setting them to the ascii null character, for
example:
              


              
  
              nedit*fileMenu.mnemonic: \0
              

              

              
              



I have a PC-style 2-button mouse and I would like to switch the 2nd and 3rd
(emulated) mouse buttons



              I have a PC-style 2-button mouse.  Can I switch the 2nd and 3rd mouse
buttons so the more important functions like secondary selection are on
the right button instead of the middle (which is emulated by pressing 1+3
buttons simultaneously under Linux), like they were in version 4?
              
              




              It's somewhat involved and hard to figure out from the documentation, but
yes you can.  You have to reverse the translation table bindings for mouse
buttons 2 and 3, AND reset the bgMenuButton resource.  The translation table
bindings can either be found in the source file source/text.c, or by adding
and activating a temporary translation to the text widget for dumping the
translation table itself (XtDisplayTranslations()).
              


              What it boils down to, though, is just add the following lines to your X
resource file (.Xdefaults or .Xresources depending on your system):
              


                NEdit*text.Translations: #override \n\
     <Btn3Down>: secondary_or_drag_start()\n\
     Shift Ctrl Button3<MotionNotify>: \
         secondary_or_drag_adjust("rect", "copy", "overlay")\n\
     Shift Button3<MotionNotify>: secondary_or_drag_adjust("copy")\n\
     Ctrl Button3<MotionNotify>: secondary_or_drag_adjust("rect", "overlay")\n\
     Button3<MotionNotify>: secondary_or_drag_adjust()\n\
     Shift Ctrl<Btn3Up>: move_to_or_end_drag("copy", "overlay")\n\
     Shift <Btn3Up>: move_to_or_end_drag("copy")\n\
     Alt<Btn3Up>: exchange()\n\
     Meta<Btn3Up>: exchange()\n\
     Ctrl<Btn3Up>: copy_to_or_end_drag("overlay")\n\
     <Btn3Up>: copy_to_or_end_drag()\n\
     Ctrl~Meta~Alt<Btn2Down>: mouse_pan()\n\
     Ctrl~Meta~Alt Button2<MotionNotify>: mouse_pan()\n\
     <Btn2Up>: end_drag()
  nedit.bgMenuButton: ~Shift~Ctrl~Meta~Alt<Btn2Down>

              

              
              


How can I make a shell command prompt me for input?



              I'd like to send mail directly from my nedit window, but there's no good
way to make a shell command prompt me for input (for entering the recipient
and subject).
              
              




              Use a macro command instead to do the prompting:
              


                to = string_dialog("Send mail to: (enter name below, along with any\n" \
      "additional Unix Mail command parameters, -s for subject)", \
      "Send", "Cancel")
  if ($string_dialog_button == 2 || $string_dialog_button == 0)
      return
  if ($selection_start == -1)
      body = get_range(0, $text_length)
  else
      body = get_selection()
  cmdOutput = shell_command("Mail " to, body)
  if ($shell_cmd_status != 0)
      dialog("mail command returned failed exit status\n" cmdOutput)
  else if (cmdOutput != "")
      dialog(cmdOutput)

              

              
              


How I can set the foreground color for selected
text when syntax highlighting is applied?



              How I can set the foreground color for selected
text to be always say grey1 even when syntax highlighting is applied?
              
              




              There's no equivalent to the
nedit*text.selectForeground resource when you turn on
syntax highlighting.  You just have to choose a selection color that
is compatible with all of your highlighting colors.

Why NEdit does not support drag and drop?



              I'm a little confused about what happend to drag and drop.
I thought drag-N-drop was supported by the Motif library.
              
              




              NEdit no longer uses the Motif text widget, so all of the functionality
had to be duplicated in the new widget.  Drag and drop between windows got
left off due to time pressure of getting out the new release, but it will
be back some day.
              

              
              


Why don't you integrate Max Vohlken's / Yunliang Yu's versions into the
official release of NEdit




              Many of their changes will eventually find their way in to the "official"
version, but some will not.  Max has really done quite a lot of stuff.
I appreciate it, and I think it's kind of neat to have a "bleeding edge"
version of NEdit around to try out new features.  
              


              I can't just apply Max's patches to our version and release it.  Some of
them break the VMS version, some interfere with existing commands that
are important to other users, and some are just customizations that I
don't particularly agree with.  Mostly, I want to do a lot of testing to
make sure the changes are safe on all platforms, and I just don't have
time right now.  (Mark Edel)
              


              Update as of NEdit version 5.2RC1: The forthcoming
NEdit version 5.2 contains several functionalities of Max's patches.
              

              
              



Is it possible to use NEdit on windows 95 or NT?



              I really like nedit and it would be nice to use on windows 95 or NT
instead of word or notepad.  Is this possible?
              
              




              There is an NT version of NEdit, available at
http://nedit.org/download/win32.shtml. A mini-FAQ is also
available.
              

              
              


Why aren't there pre-entered default values in text fields of dialogs?



              A feature which is found in in some Macintosh and PC programs, which I
like, is to provide pre-entered default values in text fields.  For example,
the find and replace dialogs could show the last search/replace string, or
the currently selected text.  These programs select the text, so simply
typing in the field automatically replaces the default without any extra
work from the user.
              
              




              X has a strict convention that there can be only one selection at
a time on the whole display.  This means that some of the tricks used
in PC and Macintosh programs don't work in X.  On PCs and Macs,
programs can fill in default values in text fields, and select the
text that they have inserted such that If the user types over the
selection, it will automatically be erased.  Under X, there is a
price to pay for making an automatic selection.  The selection must
be "stolen" from some other window, maybe some other program. If the
user's intent was to paste a selection that existed before the dialog
popped up, once the automatic selection is made, they are out of

              If NEdit automatically transferred the selection to the Find or Replace
dialog, it would either have to steal the selection, or users would
have to click or drag the mouse over the text to delete it before they
could type anything different.  Instead, NEdit has a "Find Selection"
command, as well as various methods of pasting and copying the
selection into dialog fields.  It also allows you to recall of previous
search strings in the Find and Replace dialogs via the up-arrow and
down-arrow keys.
              

              
              


I would like to use (multiple fonts, special symbols) in my file, but
NEdit seems to allow just one single font.




              NEdit is a plain text editor, not a word processor.  Plain text files have
no font or formatting information contained in them, they are just a string
of ascii characters.  While you might find a font with limited symbols and
greek letters, your troubles would just be beginning.  You'd still have
trouble getting the printer to agree and print out the characters as they
appeared in NEdit.  For anything involving font changes or special symbols,
you need a word processor, such as Microsoft Word, or a text
formatting program like LaTEX.
              

              
              


Auto-wrap doesn't work well



              Auto-wrap doesn't work very well.  When I type in the middle of a line, I
can push the end of the line beyond the right margin, and when I delete,
It doesn't keep the right edge of the text lined up.
              
              




              You probably want continuous wrap mode (Preferences -> Wrap
-> Continuous).
              


              Because NEdit is not a word processor, it is stuck with the limits
of the plain text format. In the default, auto-newline, wrapping
mode, nedit does wrapping by inserting newline characters.  Because
there is only one newline character, NEdit can't distinguish a
newline which can be "unwrapped" from one which the user intended to
be permanent.  While it might be possible for NEdit to temporarily
make that distinction, for example while the cursor is on a
particular line that the user is typing, ultimately, NEdit will have
to forget this information, because there is no way to save it in the
file. Users who work in auto-newline wrap mode tend to make liberal
use of the Fill paragraph command.
              


              In continuous wrapping mode, you can intentionally leave out the
newlines within paragraphs, and lines will be wrapped as needed to
fit within the page.  When you edit in the middle of a paragraph, the
text will be continuously adjusted.  However, continuous wrap mode
has it's limitations too.  All paragraphs must be lined up against
the right margin to take advantage of continuous wrapping, and Unix
systems have limited support for files of that format.  You may have
trouble printing and viewing the files outside of NEdit.
              

              
              


NEdit scrolls too fast when I extend a selection by dragging the mouse
outside of the window.




              NEdit features proportional auto-scrolling, where the
speed is controlled by how far your mouse is beyond the edge of the
window.  If you want it to scroll slower, bring the mouse back closer
to the text.
              

              
              


Is there a special symbol that represents the selected text,
usable in shell commands?



              Is there a special symbol (as % for filename in the shell commands)
that can be used to represent the text that is selected, which can then
be used as an argument to a command? For instance, I want to feed the
selection to a script so that it can be used as the expression to a
'grep' command. Is there any other way that I can accomplish this goal?
              
              




              Below is an example from the NEdit discussion list (from David L. Paterline)
of a "Find All" command implemented by using the selection as an argument to
the grep command:
              


              
   
              I set up a command to list all lines in a file which contain the
   highlighted selection as follows, using the Preferences -> Shell
   Commands menu:
              


                      Menu Entry:           all <selection>
        Command Input:        selection
        Command Output:       new window
        Save file before:     yes
        Shell Command:        grep -n -- "`cat -`" %

              

   
              The cat - portion of the command echoes the selected text to the
   grep -n command, which lists the lines containing the selection
   with line numbers.  The output of the command appears in a new
   window; I can then highlight a line number in the new window and
   use the Search -> Goto Selected menu in the original window to jump
   to the line in the original file.
              

              

              
              


How can I print highlighted text on my printer as it appears in NEdit.




              In the current version, that's not possible, but there are external tools
for highlighting, which are specifically designed for printing, including
a2ps, enscript, and genscript.
              

              
              



              














              

Server mode and nc


I want to use nc as an external
editor from my mailer, but my mailer doesn't wait for the editor
to finish



              I use a mailer
which can invoke an external editor, but if I use nc, the mailer process
continues and assumes the editor has finished, when in fact it hasn't.
              
              




              nc is actually finished communicating with the NEdit server when it
returns.  It's possible to create a shell command that invokes nc and
then goes to sleep, and a second script to be run from the NEdit Shell
menu, which looks for the sleeping process with a matching file name
and kills it.  Try the shell scripts in:
              


              

              
ftp://ftp.nedit.org/pub/contrib/misc/nc_and_wait.tar

              

              

              
              


I started nedit as root, then tried later to edit a file as myself with
nc; the file was opened in the root's nedit

 
              I started nedit (via nc) as root, and then
later tried to edit a file as myself with nc. I was very
suprised to see that a new nedit wasn't started--rather, I was given
the old nedit window, with root permissions. Isn't this a security
hole?
                             




              Actually, NEdit does check who the user is.  When you use the su
command, however, several Unix variants return the original user name
in response to the standard C library calls for getting a user name,
rather than the name to which you have su'd.  Starting with version 5.1,
a different mechanism is used for getting this information, so you shouldn't
see this problem any more.
              


              In your case, my guess is that you used su to become root, then
started an nedit server as root.  On a system which returns the
original user name, both the new server and the nc client program
think the user name is your original user name, so the server accepts
requests from both you as root and you as you.
              


              The security of an nedit session, depends upon the security of your X
server.  Only those with access to your screen can send commands to an
nedit server, but they can also send keystrokes to any nedit, or a shell
window, etc...  Anyhow, just upgrade to the latest NEdit version.
              

              
              


              














              

Editing techniques


I'd like to select a large expanse of text
without dragging all the way through it with the mouse.




              Using the shift key with the left mouse button, you can select all of the text
between the cursor (or an existing selection) and the mouse.
              


                
  
              • Position the cursor at one end of the desired selection
                • 
  
              • Use the scroll bar to make the other end visible
                • 
  
              • Shift+Click with the left mouse button to select the text between
     the cursor and the mouse
                • 

              


              Alternatively, using only keyboard navigation:
              


                
  
              • Position the cursor at one end of the desired selection
                • 
  
              • Type Alt-m and a letter to mark the position
                • 
  
              • Use the keyboard to go to the other end of the desired selection
                • 
  
              • Type Shift-Alt-g and the letter you used to mark the first end
  of the selection
                • 

              


              
              


How can I select the text between two marks?

              • Hold the shift key while selecting Goto Mark or Alt+Shift+G to
    select the text.

Bugs


The keyboard shortcuts (accelerator keys) are not
working when 'Caps' or 'Num Lock' are switched on.



              The keyboard shortcuts (accelerator keys) are not
working when 'Caps' or 'Num Lock' are switched on.  Have I
overlooked something obvious?
              
              




              You haven't overlooked anything, it's a Motif design flaw.  Netscape
painfully works around this and the Alt/Meta key reversal on Sun
workstations by internally re-implementing the Motif menu accelerator
mechanism.  NEdit will likely follow suit with the release of version 5.2.
              


              Another possibility (writes Peter Daifuku of SGI):
              


              
   
              There's another answer which unfortunately isn't widespread as yet.
   For an X11R6.3 X server supporting the XKB extension, there is a
   mechanism to ignore the NumLock and CapsLock key as modifiers. The
   file /usr/lib/X11/xkb/X0-config.keyboard should contain the string
   IgnoreLockMods=NumLock+Lock . For systems with multiple displays,
   display 1 would be controlled by the file X1-config.keyboard, etc.
              
 
   
              On SGI systems, this mechanism is support on IRIX 6.2 with X server
   patch 1574 or later, on IRIX 6.3 and IRIX 6.4 and all later releases.

              Sometimes NEdit inserts <dc3> instead of saving the
file when I type ^S. Other keyboard shortcuts (accelerator keys) don't
work either.
              
              


You have probably NumLock or CapsLock ON. See the answer to
this question.


              





Joor Loohuis
I use the numeric keypad really often, so I keep NumLock on.
But NEdit shortcuts don't work when NumLock is on.



              The bug is not in NEdit, but in Motif. This is fixed as of NEdit 5.2, but
that might not help you much. Older versions have the same problem.
              


              Here's how you tell X to interpret the keypad keys as numbers without
turning NumLock on. Create a file .Xmodmap in your home directory, and put the
following lines in it:
              


                keycode  79 = KP_7
  keycode  80 = KP_8
  keycode  81 = KP_9
  keycode  83 = KP_4
  keycode  84 = KP_5
  keycode  85 = KP_6
  keycode  87 = KP_1
  keycode  88 = KP_2
  keycode  89 = KP_3
  keycode  90 = KP_0
  keycode  91 = KP_Decimal

              


              Then make sure the script that starts your X session parses this file with
the command:
              

                xmodmap -merge ~/.Xmodmap

              


              This script can be ~/.xinitrc (called by startx) or something like Xsession
if you use xdm/kdm/gdm. Then again, it might be an entirely different script on
some systems.
              


              Then turn off numlock, and just continue using the keypad. The only thing
is, you loose the alternate set of functions (cursor/home/pgdown/etc).
              


              

              






NEdit crashes I try to paste text in to a text field in a dialog
(like Find or Replace) on my SunOS system.




              On many SunOS systems, you have to set up an nls directory before
various inter-client communication features of Motif will function
properly.  Before NEdit 4.0 this wasn't much of a problem, because
users couldn't cut and paste at all, and Motif would sometimes
print a warning about not finding an nls directory, so most users
figured it out right away.  But with 4.0, everything seems to be
working fine, except when someone tries to move text in or out of
a dialog field, then blamo.
              


              There are instructions in README.sun in
ftp://ftp.nedit.org/pub/<current-version<,
as well as a tar file containg a complete nls directory:
ftp://ftp.nedit.org/pub/<current-version</individual/README.sun

              


              It contains directions for setting up an nls directory, which is
required by Motif for handling copy and paste to Motif text fields.
              

              
              


NEdit crashes frequently, particularly on window closing.




              There is an obsolete resource in Motif called defaultFontList, which
does nothing but cause random crashing.  I don't know why NEdit users
keep popping up with this resource set, maybe it looks enticing when
you look at widget resources with editres.  Anyhow, setting it to
anything, whether it be a valid font or just garbage, causes random
crashing in both Motif 1.2 and 2.0, so just don't set it.
              

              
              


NEdit sometimes crashes when I execute a shell command menu item I
just added.




              Check the "Command Input" setting, in the Preferences->Shell Commands
dialog for that menu item.  If the shell command being executed does
not take input, but "Command Input" is set to "selection" or "window",
NEdit tries to write the input anyhow, and fails.  Set "Command Input"
to "none" to prevent this possibility.  This is fixed in version 5.1 and later.
              

              
              



When NEdit starts up, I get errors like:
Cannot allocate colormap entry for "#b3b3b3".

   



              When NEdit starts up, I get errors:
              


                 Cannot allocate colormap entry for "#b3b3b3"
   Cannot allocate colormap entry for "#e5e5e5"

              
              




              Most X displays are set up to operate in a mode which allocates 8
bits of video memory per-pixel, and requires a color mapping table to
translate pixel values to screen colors.  With just 8 bits there are
only 256 possible colors, and programs must either allocate and share
these pixel values, or swap in their own colormap and make all other
windows flash to strange colors while their window is focused.  Some
programs, Netscape in particular, are bad neighbors in this
environment and snarf up every free entry in the shared colormap,
such that every program that runs after them gets the errors you're
asking about.
              


              The solution is either to start Netscape last, after all other applications
that you might want to run, or better, tell Netscape how many colors it is
allowed to allocate.  Fortunately, you can do this with a resource setting:
              


              

              Netscape*maxImageColors: 80
              

              

              
              



Sometimes when I use regular expression replacement inside of a
rectangular selection, NEdit fails to match text.



              Sometimes when I use regular expression replacement inside of a
rectangular selection, NEdit fails to match text which does legally
match the expression.
              
              




              The problem with REs and rectangular selections is that matching is
bounded by the rectangular selection, but text outside of the selection
is still fed to the matching routines, so ^, $, don't refer to the
edges of the selection, they still refer to the beginning and ending of
the line, and some legal matches are excluded because they continue
outside of the selection are thereby excluded, or are shadowed by
matches which begin or end outside of the selection.
              

              
              



When ever I execute a nedit shell command (such as spell or wc) I get
extra junk.



              When ever I execute an nedit shell command (such as spell or wc) I get
(extra junk, error messages, complaints from stty) inserted into my text,
or an Information dialog with (extra junk, error messages, complaints
from stty).
              
              




              You probably have printing commands in your shell startup file (.cshrc, or
equivalent).  These should either be skipped in non-interactive mode, or
moved to your .login file.  You can often see the problem outside of nedit
by typing:
              


                  csh -c ls

              


              Error messages from stty are a result of it being executed from a process
which isn't attached to a terminal.  You can safely move stty statements
and most other interactive commands to your .login file (calling stty from
a .cshrc file is redundant because the terminal device doesn't change for
each sub-shell).  If you can't remove interactive commands, you should
skip around them in non-interactive shells, I think the usual method is to
put them at the end, preceded by something like:
              


                  if ($?prompt == 0) exit

              


              The manual entry on csh has more information on this.
              

              
              


On a Solaris system, the right part of the 'file open' dialog
is too narrow, I can't see the complete file names.



              On a Solaris system, when trying to open a file within nedit, you get the
listing of available file names. However, the sub-window (on the right)
containing the file names (not directory names) sometimes is too narrow so
that you can't see the filename part (i.e. /usr/people/rainer/sometextfile.txt
shows up as /usr/people/rain or so). When resizing the dialog box, the
filenames sub-window on the right doesn't become larger. I know I can use
nedit.stdOpenDialog to type a filename, but that's annoying.
              
              




              It's a bug in the shared Motif library.  Depending on your system, the patch
is one of ID# 103461-07, # 102226-19, or # 103186-21.  If you can't patch
your system, you can set the resource:
              


                  nedit*XmFileSelectionBox.pathMode:  XmPATH_MODE_RELATIVE

              


              This will stop the dialog from displaying the path component of
file names. Another possible workaround is to use the nedit_sunos
executable (from ftp://ftp.nedit.org/pub/), which is
statically linked with a good Motif.

              In some versions of S.u.S.E. Linux, there's apparently something wrong
with their builds of NEdit and other Motif apps.  I've been told you

/lib/libBrokenLocale.so.1 before launching it.  You can also use the
statically linked version of NEdit for Linux from

NEdit seems to be running very slowly on my Solaris 2.6 system.




              If you're running NEdit on a Solaris 2.6 system and experiencing performance
problems (windows come up slowly), the patch for Sun's shared Motif library

dramatically.  The patch also enables a resource, *XmMenuReduceGrabs.
Setting this to True will eliminate the delay completely.

                 (filename): forward host lookup failed:
               Host name lookup failure: Connection refused

              

              




              There is another program called nc which is installed on
some systems. In this case, nc is for netcat,
some kind of network diagnostic tool. You can safely rename NEdit's
nc to something else (we recommend ncl), or put it first in
your path before netcat.
              

              
              


Whenever I try to open existing files by using menu, nedit crashes; but
if I type nedit filename command, it works.



              Whenever I try to open existing files by using menu, nedit crashes, and
sometimes I get the following error message:
              


                 X Error of failed request:  BadAlloc (insufficient resources for operation)
   Major opcode of failed request:  53 (X_CreatePixmap)

              


              But if I type nedit filename command, it works. So
how can I open file by using menu bar?
              

              




              Several users have reported this problem.  Most of them were using
S.u.S.E. Linux .  A few others had different
distributions, but always European.  The problem appears to be related
to how Motif searches for named pixmaps and bitmaps.  My guess is that on
some systems, this search encounters a match with a bad pixmap file, or
tries to load something which is not a pixmap at all.  One solution was
to set the environment variable XBMLANGPATH to a random directory.  For
example:
              


                XBMLANGPATH=.
  export XBMLANGPATH

              


              The solution on S.u.S.E Linux systems was to remove an unnecessary line
in the global /etc/profile (provided by S.u.S.E.):
              


                export XAPPLRESDIR=
      "$XAPPLRESDIR:/var/X11R6/app-defaults:/usr/X11R6/lib/X11/app-defaults"

              


              Another user who had the problem reported that the root cause appeared to
be insufficient read permissions on some xm_* (e.g. xm_warning) pixmaps in
"/usr/X11R6/include/X11/bitmaps".  (Could someone else confirm this?)
              

              
              


I want to be able to spawn a command from NEdit.



              I want to be able to spawn a command from NEdit.  By this I mean that I
want to NEdit to launch another program without waiting for the program
to return.  At the moment I'd like to be able to launch
mctags, but I
also have a variety of other things I'd like to do.  The shell command:
mctags & continues to wait
for mctags to finish, despite the "&".  Is
there any way to do what I want?
              
              




              It's a bug/feature of NEdit that it considers a shell command process
alive as long as any of it's file descriptors remain open.  Forked
processes generally copy and keep open the stdout and stderr descriptors
from their parent process, so you have to add
>& /dev/null to your shell
command, so it reads:
              


                  mctags >& /dev/null &

              

              
              


NEdit flashes or matches the wrong parenthesis, bracket, or brace if there
is an intervening paren/bracket/brace quoted in between.




              Until version 5.0, NEdit had no way of even knowing what
language you were operating in when making the flash/match decision, so it
simply counted opening and closing instances, disregarding language syntax
context (strings, comments, etc.) completely.  Now that the feature is more
possible to implement, it may be included in a future version, but I'm not
entirely sure how best to do it yet.
              

              
              


I'd like to edit a file which is about 50 Megabytes long,
but I get errors.



              I'd like to edit a file which is about 50 Megabytes long.
Whenever I try to read this file, there was always a message as following:
              


                  Error: Cannot perform realloc

              
              




              How large a file you can edit with NEdit depends on how much swap space + RAM
you have, since it loads your file into virtual memory and occasionally does a
full copy of that memory space.  NEdit can handle a 100MB file reasonably well
if you increase your swap space, but I don't know how far beyond that it can
go.  To work with a 100MB file, you must have at least 200MB of virtual memory
available.  Many Unix systems can be set up to temporarily increase swap space
by creating a temporary swap file.
              

              
              


We installed NEdit Version 5.0 recently, and the
accelerators Ctrl-G (Find again) and Ctrl-L (Goto Line Number) are now
missing




              You have an out-of-date app-defaults file.  We strongly recommend not using
such files for this exact reason.  When you use an app-defaults file, it
replaces ALL of the program defaults.  If you do install an app-defaults file,
it is your responsibility to keep it up to date with each new release of the
executable.  Otherwise, as you have observed, certain features will degrade
with each release, as the app-defaults file and the executable get further and
further out of sync with eachother.
              

              
              


On our PCs we have Windows 3.1 and we run XVision as X-Server and
we cannot mark with the mouse within NEdit.



              On our PCs we have Windows 3.1 and we run XVision as X-Server. The problem
that we have is, that we cannot mark with the mouse within NEdit.
              


              When you click and hold the left mouse button and then move the mouse, you
can see the mark-area flickering during the movement of the mouse. When
stopping the movement nothing is highlighted and nothing is marked.
              
              




              XVision is grabbing the selection immediately, as soon as it is made, not
allowing applications to own it.  This behavior is completely wrong, and I
have no idea what they might have been thinking when they implemented it.  It
may be possible to turn it off, ask their technical support people if they're
not already out of business.
              

              
              


My regular expression replacement got truncated!



              My regular expression replacement got truncated! I wrote
a regular expression to nest additional braces around blocks of code
(replace {([^{}]|\n)*} with {\0}), which works for
small blocks of text, but it fails on large ones, truncating the
replacement at around 512 bytes.
              
              




              A remnant of pre-regular-expression, pre-macro-language NEdit, is that
replacement strings are limited to 511 bytes.  This is high on the list
to fix in a future upgrade.
              

              
              


NEdit is slow and pages continuously on my 8MB Linux system




              On most Unix workstations, 8MB of RAM is actually insufficient to run X
and Motif properly.  Some Linux users get by with it and Linux itself
seems to be quite memory efficient, but you really should have 12 or 16
if you're going to be using X much.  NEdit would not be my first choice
in editors on an 8MB system.
              

              
              


Some of the special keys on my keyboard don't do what I expect.




              X systems are rife with this kind of problem because are just too many
levels of re-settable bindings between the keyboard and the application
program that reads it.  Sun systems are the worst offenders, combining
poor Motif support with a variety of strange keyboard arrangements.
              


              To diagnose these problems, you have to look at all three levels of key
binding that affect Motif programs.
              


              At the bottom level are the modifier map and keymap table, where
hardware key codes are bound to X keysyms.  You can see the bindings on
this level with the xmodmap program (see man xmodmap).  A useful tool
in debugging the xmodmap level is a program like xev, which can show
you the keysyms it receives.
              


              The next level up from that is the motif virtual binding level
(see man VirtualBindings).  You can (usually) view the bindings at
this level by looking at the value of the root window property:
_MOTIF_DEFAULT_BINDINGS, using the xprop -root command, however what
you see is not necessarily what you'll get.  The defaults for these
bindings are determined by an unbelievably complicated process
involving not just the application in question, but Motif
applications which have run before it attached to the same server.
This process is described in detail in the VirtualBindings manual
page (which is often not available on systems where the bindings are
messed up). While it's usually better to attack system configuration
problems at the source, this one is so contorted that you're better
off with a patch. Luckily, the default Motif virtual bindings can be
overridden by an application resource called defaultVirtualBindings.
If you think the problem is at the Motif virtual binding level,
define a defaultVirtualBindings resource in your .Xresources or
.Xdefaults file, using the example below as a template, replacing the
keysym names (to the right of the colon) with the keysyms shown by
xev when you press the desired key:
              


                 !
   ! Motif Virtual Key Bindings
   !
   nedit*defaultVirtualBindings: \
        osfActivate     :               <Key>KP_Enter\n\
        osfCancel       :               <Key>Escape\n\
        osfHelp         :               <Key>Help\n\
        osfMenu         :               <Key>F4\n\
        osfMenuBar      :               <Key>F10\n\
        osfLeft         :               <Key>Left\n\
        osfUp           :               <Key>Up\n\
        osfRight        :               <Key>Right\n\
        osfDown         :               <Key>Down\n\
        osfBeginLine    :               <Key>Home\n\
        osfEndLine      :               <Key>End\n\
        osfPageUp       :               <Key>Prior\n\
        osfPageDown     :               <Key>Next\n\
        osfBackSpace    :               <Key>BackSpace\n\
        osfDelete       :               <Key>Delete\n\
        osfInsert       :               <Key>Insert\n\
        osfUndo         :               <Key>F14\n\
        osfAddMode      :Shift          <Key>F8\n\
        osfCopy         :               <Key>F16\n\
        osfCut          :               <Key>F20\n\
        osfPaste        :               <Key>F18\n

              


              If NEdit is having binding problems, chances are that other Motif-based
programs are also having trouble.  Removing the "nedit" from the resource
name above (just *defaultVirtualBindings), will apply it to the other
Motif programs that you run as well.
              


              The top level bindings in the key binding hierarchy, are the X toolkit
translation tables (see the NEdit Help section called X Resources).  To
show the translations in use, you can add a binding which dumps the table
itself:
              


                  nedit*text.Translations: #override \
        Alt<Key>t: XtDisplayTranslations()\n

              


              Typing Alt+T will then display the contents of the translation table to
stdout (the terminal from which you started NEdit).  If you have the NEdit
source, you can also look at the default bindings in the module text.c.
              


              Sometimes, even if you don't understand the problem, you can patch around it
by supplying translations for the keysyms that NEdit actually sees, binding
them to the action routines that you want activated when you press that
key.
              

              
              


KP Enter does no longer executes the current line or selected text as
   a shell command. How can I get this behavior back?




              It was considered dangerous to have a commonly used key potentially
   execute arbitrary shell commands unintentionally (think rm -Rf). Therefore
   the shortcut was changed to Ctrl+KP Enter.
   
   In case you want the old binding back, you can add the following lines
   to your .Xdefaults or .Xresources file:
              
   

                 nedit*shellMenu.executeCommandLine.accelerator: <Key>KP_Enter",
   nedit*shellMenu.executeCommandLine.acceleratorText: KP Enter",

  Welcome to NEdit!
.. ~ NEDITDOC
.. .. What appears below will always print whether or not NEDITDOC is defined.
..

  NEdit is a standard GUI (Graphical User Interface) style text editor for
  programs and plain-text files.  Users of Macintosh and MS Windows based text
  editors should find NEdit a familiar and comfortable environment.  NEdit
  provides all of the standard menu, dialog, editing, and mouse support, as
  well as all of the standard shortcuts to which the users of modern GUI based
  environments are accustomed.  For users of older style Unix editors, welcome
  to the world of mouse-based editing!

.. ? NEDITDOC~
..   NEdit is freely distributed under the terms of the Gnu General Public
..   License.

.. .. This stuff will always be invisible, unless NEDITDOC is defined
..
.. Installing NEdit
.. ----------------
..
..   NEdit is a single stand-alone executable file which can be installed by simply
..   copying the appropriate executable "nedit" for your system.  Both sources and
..   executables are available from http://www.nedit.org.  The optional "nc" (NEdit
..   Client) program is also available for users who want to run nedit in
..   client/server mode.
..
.. Getting Started
.. ---------------
.. ~ NEDITDOC

  Help sections of interest to new users are listed under the "Basic Operation"
  heading in the top-level Help menu:

      Selecting_Text_
      Finding_and_Replacing_Text_
      Cut_and_Paste_
      Using_the_Mouse_
      Keyboard_Shortcuts_
      Shifting_and_Filling_

  Programmers should also read the introductory section under the "Features for
  Programming" section:

      Programming_with_NEdit_

  If you get into trouble, the Undo command in the Edit menu can reverse any
  modifications that you make.  NEdit does not change the file you are editing
  until you tell it to Save.

3>Editing an Existing File

  To open an existing file, choose Open... from the file menu. Select the file
  that you want to open in the pop-up dialog that appears and click on OK.  You
  may open any number of files at the same time.  Depending on your settings
  (cf. "Tabbed_Editing_") each file can appear in its own editor window, or it
  can appear under a tab in the same editor window.  Using Open... rather than
  re-typing the NEdit command and running additional copies of NEdit, will give
  you quick access to all of the files you have open via the Windows menu, and
  ensure that you don't accidentally open the same file twice.  NEdit has no
  "main" window.  It remains running as long as at least one editor window is
  open.

3>Creating a New File

  If you already have an empty (Untitled) window displayed, just begin typing
  in the window.  To create a new Untitled window, choose New Window or New Tab
  from the File menu.   To give the file a name and save its contents to the
  disk, choose Save or Save As... from the File menu.

3>Backup Files

  NEdit maintains periodic backups of the file you are editing so that you can
  recover the file in the event of a problem such as a system crash, network
  failure, or X server crash.  These files are saved under the name `~filename`
  (on Unix) or `_filename` (on VMS), where filename is the name of the file you
  were editing.  If an NEdit process is killed, some of these backup files may
  remain in your directory.  (To remove one of these files on Unix, you may
  have to prefix the `~' (tilde) character with a (backslash) to prevent the
  shell from interpreting it as a special character.)

3>Shortcuts

  As you become more familiar with NEdit, substitute the control and function
  keys shown on the right side of the menus for pulling down menus with the
  mouse.

  Dialogs are also streamlined so you can enter information quickly and without
  using the mouse*.  To move the keyboard focus around a dialog, use the tab
  and arrow keys.  One of the buttons in a dialog is usually drawn with a
  thick, indented, outline.  This button can be activated by pressing Return or
  Enter.  The Cancel or Dismiss button can be activated by pressing escape.
  For example, to replace the string "thing" with "things" type:

      thingthings

  To open a file named "whole_earth.c", type:

      who

  (how much of the filename you need to type depends on the other files in the
  directory).  See the section called "Keyboard_Shortcuts_" for more details.

  * Users who have set their keyboard focus mode to "pointer" should set
  "Popups Under Pointer" in the Default Settings menu to avoid the additional
  step of moving the mouse into the dialog.
   ----------------------------------------------------------------------

Basic Operation
===============

Selecting Text
--------------

  NEdit has two general types of selections, primary (highlighted text), and
  secondary (underlined text). Selections can cover either a simple range of
  text between two points in the file, or they can cover a rectangular area of
  the file. Rectangular selections are only useful with non-proportional (fixed
  spacing) fonts.

  To select text for copying, deleting, or replacing, press the left mouse
  button with the pointer at one end of the text you want to select, and drag
  it to the other end. The text will become highlighted. To select a whole
  word, double click (click twice quickly in succession). Double clicking and
  then dragging the mouse will select a number of words. Similarly, you can
  select a whole line or a number of lines by triple clicking or triple
  clicking and dragging. Quadruple clicking selects the whole file. After
  releasing the mouse button, you can still adjust a selection by holding down
  the shift key and dragging on either end of the selection. To delete the
  selected text, press delete or backspace. To replace it, begin typing.

  To select a rectangle or column of text, hold the Ctrl key while dragging the
  mouse. Rectangular selections can be used in any context that normal
  selections can be used, including cutting and pasting, filling, shifting,
  dragging, and searching. Operations on rectangular selections automatically
  fill in tabs and spaces to maintain alignment of text within and to the right
  of the selection. Note that the interpretation of rectangular selections by
  Fill Paragraph is slightly different from that of other commands, the section
  titled "Shifting_and_Filling_" has details.

  The middle mouse button can be used to make an additional selection (called
  the secondary selection). As soon as the button is released, the contents of
  this selection will be copied to the insert position of the window where the
  mouse was last clicked (the destination window). This position is marked by a
  caret shaped cursor when the mouse is outside of the destination window.  If
  there is a (primary) selection, adjacent to the cursor in the window, the new
  text will replace the selected text. Holding the shift key while making the
  secondary selection will move the text, deleting it at the site of the
  secondary selection, rather than copying it.

  Selected text can also be dragged to a new location in the file using the
  middle mouse button. Holding the shift key while dragging the text will copy
  the selected text, leaving the original text in place. Holding the control
  key will drag the text in overlay mode.

  Normally, dragging moves text by removing it from the selected position at
  the start of the drag, and inserting it at a new position relative to the
  mouse. Dragging a block of text over existing characters, displaces the
  characters to the end of the selection. In overlay mode, characters which are
  occluded by blocks of text being dragged are simply removed. When dragging
  non-rectangular selections, overlay mode also converts the selection to
  rectangular form, allowing it to be dragged outside of the bounds of the
  existing text.

  The section "Using_the_Mouse_" summarizes the mouse commands for making primary
  and secondary selections. Primary selections can also be made via keyboard
  commands, see "Keyboard_Shortcuts_".
   ----------------------------------------------------------------------

Finding and Replacing Text
--------------------------

  The Search menu contains a number of commands for finding and replacing text.

  The Find... and Replace... commands present dialogs for entering text for
  searching and replacing.  These dialogs also allow you to choose whether you
  want the search to be sensitive to upper and lower case, or whether to use
  the standard Unix pattern matching characters (regular expressions).
  Searches begin at the current text insertion position.

  Find Again and Replace Again repeat the last find or replace command without
  prompting for search strings.  To selectively replace text, use the two
  commands in combination: Find Again, then Replace Again if the highlighted
  string should be replaced, or Find Again again to go to the next string.

  Find Selection searches for the text contained in the current primary
  selection (see Selecting_Text_).  The selected text does not have to be in the
  current editor window, it may even be in another program.  For example, if
  the word dog appears somewhere in a window on your screen, and you want to
  find it in the file you are editing, select the word dog by dragging the
  mouse across it, switch to your NEdit window and choose Find Selection from
  the Search menu.

  Find Incremental, which opens the interactive search bar, is yet another variation
  on searching, where every character typed triggers a new search.  After you've
  completed the search string, the next occurrence in the buffer is found by hitting
  the Return key, or by clicking on the icon to the left (magnifying glass). Holding
  a Shift key down finds the previous occurrences.  To the right there is a clear
  button with an icon resembling "|<". Clicking on it empties the search text widget
  without disturbing selections.  A middle click on the clear button copies the
  content of any existing selection into the search text widget and triggers a new
  search.

3>Searching Backwards

  Holding down the shift key while choosing any of the search or replace
  commands from the menu (or using the keyboard shortcut), will search in the
  reverse direction.  Users who have set the search direction using the buttons
  in the search dialog, may find it a bit confusing that Find Again and Replace
  Again don't continue in the same direction as the original search (for
  experienced users, consistency of the direction implied by the shift key is
  more important).

3>Selective Replacement

  To replace only some occurrences of a string within a file, choose Replace...
  from the Search menu, enter the string to search for and the string to
  substitute, and finish by pressing the Find button.  When the first
  occurrence is highlighted, use either Replace Again (^T) to replace it, or
  Find Again (^G) to move to the next occurrence without replacing it, and
  continue in such a manner through all occurrences of interest.

  To replace all occurrences of a string within some range of text, select the
  range (see Selecting_Text_), choose Replace... from the Search menu, type the
  string to search for and the string to substitute, and press the "R. in
  Selection" button in the dialog.  Note that selecting text in the Replace...
  dialog will unselect the text in the window.

3>Replacement in Multiple Documents

  You can do the same replacement in more than one document at the same time.
  To do that, enter the search and replacement string in the replacement dialog
  as usual, then press the 'Multiple Documents...' button. NEdit will open
  another dialog where you can pick any document in which the replacement should
  take place. Then press 'Replace' in this dialog to do the replacement. All
  attributes (Regular Expression, Case, etc.) are used as selected in the main
  dialog.

   ----------------------------------------------------------------------

Cut and Paste
-------------

  The easiest way to copy and move text around in your file or between windows,
  is to use the clipboard, an imaginary area that temporarily stores text and
  data.  The Cut command removes the selected text (see Selecting_Text_) from
  your file and places it in the clipboard.  Once text is in the clipboard, the
  Paste command will copy it to the insert position in the current window.  For
  example, to move some text from one place to another, select it by dragging
  the mouse over it, choose Cut to remove it, click the pointer to move the
  insert point where you want the text inserted, then choose Paste to insert
  it.  Copy copies text to the clipboard without deleting it from your file.
  You can also use the clipboard to transfer text to and from other Motif
  programs and X programs which make proper use of the clipboard.

  There are many other methods for copying and moving text within NEdit windows
  and between NEdit and other programs.  The most common such method is
  clicking the middle mouse button to copy the primary selection (to the
  clicked position).  Copying the selection by clicking the middle mouse button
  in many cases is the only way to transfer data to and from many X programs.
  Holding the Shift key while clicking the middle mouse button moves the text,
  deleting it from its original position, rather than copying it.  Other
  methods for transferring text include secondary selections, primary selection
  dragging, keyboard-based selection copying, and drag and drop.  These are
  described in detail in the sections: "Selecting_Text_", "Using_the_Mouse_",
  and "Keyboard_Shortcuts_".
   ----------------------------------------------------------------------

Using the Mouse
---------------

  Mouse-based editing is what NEdit is all about, and learning to use the more
  advanced features like secondary selections and primary selection dragging
  will be well worth your while.

  If you don't have time to learn everything, you can get by adequately with
  just the left mouse button:  Clicking the left button moves the cursor.
  Dragging with the left button makes a selection.  Holding the shift key while
  clicking extends the existing selection, or begins a selection between the
  cursor and the mouse.  Double or triple clicking selects a whole word or a
  whole line.

  This section will make more sense if you also read the section called,
  "Selecting_Text_", which explains the terminology of selections, that is,
  what is meant by primary, secondary, rectangular, etc.


3>Button and Modifier Key Summary

  General meaning of mouse buttons and modifier keys:

4>  Buttons

      Button 1 (left)    Cursor position and primary selection

      Button 2 (middle)  Secondary selections, and dragging and
                         copying the primary selection

      Button 3 (right)   Quick-access programmable menu and pan
                         scrolling

4>  Modifier keys

      Shift   On primary selections, (left mouse button):
                 Extends selection to the mouse pointer
              On secondary and copy operations, (middle):
                 Toggles between move and copy

      Ctrl    Makes selection rectangular or insertion
              columnar

      Alt*    (on release) Exchange primary and secondary
              selections.


3>Left Mouse Button

  The left mouse button is used to position the cursor and to make primary
  selections.

    Click         Moves the cursor

    Double Click  Selects a whole word

    Triple Click  Selects a whole line

    Quad Click    Selects the whole file

    Shift Click   Adjusts (extends or shrinks) the
                  selection, or if there is no existing
                  selection, begins a new selection
                  between the cursor and the mouse.

    Ctrl+Shift+   Adjusts (extends or shrinks) the
    Click         selection rectangularly.

    Drag          Selects text between where the mouse
                  was pressed and where it was released.

    Ctrl+Drag     Selects rectangle between where the
                  mouse was pressed and where it was
                  released.


3>Right Mouse Button

  The right mouse button posts a programmable menu for frequently used commands.

    Click/Drag    Pops up the background menu (programmed
                  from Preferences -> Default Settings ->
                  Customize Menus -> Window Background).

    Ctrl+Drag     Pan scrolling.  Scrolls the window
                  both vertically and horizontally, as if
                  you had grabbed it with your mouse.


3>Middle Mouse Button

  The middle mouse button is for making secondary selections, and copying and
  dragging the primary selection.

    Click         Copies the primary selection to the
                  clicked position.

    Shift+Click   Moves the primary selection to the
                  clicked position, deleting it from its
                  original position.

    Drag          1) Outside of the primary selection:
                      Begins a secondary selection.
                  2) Inside of the primary selection:
                      Moves the selection by dragging.

    Ctrl+Drag     1) Outside of the primary selection:
                      Begins a rectangular secondary
                      selection.
                  2) Inside of the primary selection:
                      Drags the selection in overlay
                      mode (see below).

  When the mouse button is released after creating a secondary selection:

    No Modifiers  If there is a primary selection,
                  replaces it with the secondary
                  selection.  Otherwise, inserts the
                  secondary selection at the cursor
                  position.

    Shift         Move the secondary selection, deleting
                  it from its original position.  If
                  there is a primary selection, the move
                  will replace the primary selection
                  with the secondary selection.
                  Otherwise, moves the secondary
                  selection to the cursor position.

    Alt*          Exchange the primary and secondary
                  selections.


  While moving the primary selection by dragging with the middle mouse button:

    Shift         Leaves a copy of the original
                  selection in place rather than
                  removing it or blanking the area.

    Ctrl          Changes from insert mode to overlay
                  mode (see below).

    Escape        Cancels drag in progress.

  Overlay Mode: Normally, dragging moves text by removing it from the selected
  position at the start of the drag, and inserting it at a new position
  relative to the mouse. When you drag a block of text over existing
  characters, the existing characters are displaced to the end of the
  selection.  In overlay mode, characters which are occluded by blocks of text
  being dragged are simply removed.  When dragging non-rectangular selections,
  overlay mode also converts the selection to rectangular form, allowing it to
  be dragged outside of the bounds of the existing text.

  Mouse buttons 4 and 5 are usually represented by a mouse wheel nowadays.
  They are used to scroll up or down in the text window.

  * The Alt key may be labeled Meta or Compose-Character on some keyboards.
  Some window managers, including default configurations of mwm, bind
  combinations of the Alt key and mouse buttons to window manager operations.
  In NEdit, Alt is only used on button release, so regardless of the window
  manager bindings for Alt-modified mouse buttons, you can still do the
  corresponding NEdit operation by using the Alt key AFTER the initial mouse
  press, so that Alt is held while you release the mouse button.  If you find
  this difficult or annoying, you can re-configure most window managers to skip
  this binding, or you can re-configure NEdit to use a different key
  combination.
   ----------------------------------------------------------------------

Keyboard Shortcuts
------------------

  Most of the keyboard shortcuts in NEdit are shown on the right hand sides of
  the pull-down menus.  However, there are more which are not as obvious.  These
  include; dialog button shortcuts; menu and dialog mnemonics; labeled keyboard
  keys, such as the arrows, page-up, page-down, and home; and optional Shift
  modifiers on accelerator keys, like [Shift]Ctrl+F.


3>Menu Accelerators

  Pressing the key combinations shown on the right of the menu items is a
  shortcut for selecting the menu item with the mouse.  Some items have the shift
  key enclosed in brackets, such as [Shift]Ctrl+F.  This indicates that the shift
  key is optional.  In search commands, including the shift key reverses the
  direction of the search.  In Shift commands, it makes the command shift the
  selected text by a whole tab stop rather than by single characters.


3>Menu Mnemonics

  Pressing the Alt key in combination with one of the underlined characters in
  the menu bar pulls down that menu.  Once the menu is pulled down, typing the
  underlined characters in a menu item (without the Alt key) activates that
  item.  With a menu pulled down, you can also use the arrow keys to select menu
  items, and the Space or Enter keys to activate them.


3>Keyboard Shortcuts within Dialogs

  One button in a dialog is usually marked with a thick indented outline.
  Pressing the Return or Enter key activates this button.

  All dialogs have either a Cancel or Dismiss button.  This button can be
  activated by pressing the Escape (or Esc) key.

  Pressing the tab key moves the keyboard focus to the next item in a dialog.
  Within an associated group of buttons, the arrow keys move the focus among the
  buttons.  Shift+Tab moves backward through the items.

  Most items in dialogs have an underline under one character in their name.
  Pressing the Alt key along with this character, activates a button as if you
  had pressed it with the mouse, or moves the keyboard focus to the associated
  text field or list.

  You can select items from a list by using the arrow keys to move the
  selection and space to select.

  In file selection dialogs, you can type the beginning characters of the file
  name or directory in the list to select files


3>Labeled Function Keys

  The labeled function keys on standard workstation and PC keyboards, like the
  arrows, and page-up and page-down, are active in NEdit, though not shown in the
  pull-down menus.

  Holding down the control key while pressing a named key extends the scope of
  the action that it performs.  For example, Home normally moves the insert
  cursor the beginning of a line.  Ctrl+Home moves it to the beginning of the
  file. Backspace deletes one character, Ctrl+Backspace deletes one word.

  Holding down the shift key while pressing a named key begins or extends a
  selection.  Combining the shift and control keys combines their actions.  For
  example, to select a word without using the mouse, position the cursor at the
  beginning of the word and press Ctrl+Shift+RightArrow.  The Alt key modifies
  selection commands to make the selection rectangular.

  Under X and Motif, there are several levels of translation between keyboard
  keys and the actions they perform in a program.  The "Customizing_NEdit_", and
  "X_Resources_" sections of the Help menu have more information on this subject.
  Because of all of this configurability, and since keyboards and standards for
  the meaning of some keys vary from machine to machine, the mappings may be
  changed from the defaults listed below.

3>Modifier Keys (in general)

    Ctrl   Extends the scope of the action that the key
           would otherwise perform.  For example, Home
           normally moves the insert cursor to the beginning
           of a line. Ctrl+Home moves it to the beginning of
           the file.  Backspace deletes one character, Ctrl+
           Backspace deletes one word.

    Shift  Extends the selection to the cursor position. If
           there's no selection, begins one between the old
           and new cursor positions.

    Alt    When modifying a selection, makes the selection
           rectangular.

  (For the effects of modifier keys on mouse button presses, see the section
  titled "Using_the_Mouse_")

3>Specialty Keyboards

  On machines with different styles of keyboards, generally, text editing
  actions are properly matched to the labeled keys, such as Remove,
  Next-screen, etc..  If you prefer different key bindings, see the section
  titled "Key_Binding_" under the Customizing heading in the Help menu.
   ----------------------------------------------------------------------

Shifting and Filling
--------------------

3>Shift Left, Shift Right

  While shifting blocks of text is most important for programmers (See Features
  for Programming), it is also useful for other tasks, such as creating
  indented paragraphs.

  To shift a block of text one tab stop to the right, select the text, then
  choose Shift Right from the Edit menu.  Note that the accelerator keys for
  these menu items are Ctrl+9 and Ctrl+0, which correspond to the right and
  left parenthesis on most keyboards.  Remember them as adjusting the text in
  the direction pointed to by the parenthesis character.  Holding the Shift key
  while selecting either Shift Left or Shift Right will shift the text by one
  character.

  It is also possible to shift blocks of text by selecting the text
  rectangularly, and dragging it left or right (and up or down as well).  Using
  a rectangular selection also causes tabs within the selection to be
  recalculated and substituted, such that the non-whitespace characters remain
  stationary with respect to the selection.


3>Filling

  Text filling using the Fill Paragraph command in the Edit menu is one of the
  most important concepts in NEdit.  And it will be well worth your while to
  understand how to use it properly.

  In plain text files, unlike word-processor files, there is no way to tell
  which lines are continuations of other lines, and which lines are meant to be
  separate, because there is no distinction in meaning between newline
  characters which separate lines in a paragraph, and ones which separate
  paragraphs from other text.  This makes it impossible for a text editor like
  NEdit to tell parts of the text which belong together as a paragraph from
  carefully arranged individual lines.

  In continuous wrap mode (Preferences -> Wrap -> Continuous), lines
  automatically wrap and unwrap themselves to line up properly at the right
  margin.  In this mode, you simply omit the newlines within paragraphs and let
  NEdit make the line breaks as needed.  Unfortunately, continuous wrap mode is
  not appropriate in the majority of situations, because files with extremely
  long lines are not common under Unix and may not be compatible with all
  tools, and because you can't achieve effects like indented sections, columns,
  or program comments, and still take advantage of the automatic wrapping.

  Without continuous wrapping, paragraph filling is not entirely automatic.
  Auto-Newline wrapping keeps paragraphs lined up as you type, but once
  entered, NEdit can no longer distinguish newlines which join wrapped text,
  and newlines which must be preserved.  Therefore, editing in the middle of a
  paragraph will often leave the right margin messy and uneven.

  Since NEdit can't act automatically to keep your text lined up, you need to
  tell it explicitly where to operate, and that is what Fill Paragraph is for.
  It arranges lines to fill the space between two margins, wrapping the lines
  neatly at word boundaries.  Normally, the left margin for filling is inferred
  from the text being filled.  The first line of each paragraph is considered
  special, and its left indentation is maintained separately from the remaining
  lines (for leading indents, bullet points, numbered paragraphs, etc.).
  Otherwise, the left margin is determined by the furthest left non-whitespace
  character.  The right margin is either the Wrap Margin, set in the
  preferences menu (by default, the right edge of the window), or can also be
  chosen on the fly by using a rectangular selection (see below).

  There are three ways to use Fill Paragraph.  The simplest is, while you are
  typing text, and there is no selection, simply select Fill Paragraph (or type
  Ctrl+J), and NEdit will arrange the text in the paragraph adjacent to the
  cursor.  A paragraph, in this case, means an area of text delimited by blank
  lines.

  The second way to use Fill Paragraph is with a selection.  If you select a
  range of text and then chose Fill Paragraph, all of the text in the selection
  will be filled.  Again, continuous text between blank lines is interpreted as
  paragraphs and filled individually, respecting leading indents and blank
  lines.

  The third, and most versatile, way to use Fill Paragraph is with a
  rectangular selection.  Fill Paragraph treats rectangular selections
  differently from other commands.  Instead of simply filling the text inside
  the rectangular selection, NEdit interprets the right edge of the selection
  as the requested wrap margin.  Text to the left of the selection is not
  disturbed (the usual interpretation of a rectangular selection), but text to
  the right of the selection is included in the operation and is pulled in to
  the selected region.  This method enables you to fill text to an arbitrary
  right margin, without going back and forth to the wrap-margin dialog, as well
  as to exclude text to the left of the selection such as comment bars or other
  text columns.
   ----------------------------------------------------------------------

Tabbed Editing
----------------

  NEdit is able to display files in distinct editor windows, or to display files
  under tabs in the same editor window.  The Options for controlling the tabbed
  interface are found under Preferences -> Default Settings -> Tabbed Editing
  (cf. "Preferences_", also "NEdit_Command_Line_").

  Notice that you can re-group tabs at any time by detaching and attaching them,
  or moving them, to other windows. This can be done using the Windows menu, or
  using the context menu, which pops up when right clicking on a tab.

  You can switch to a tab by simply clicking on it, or you can use the keyboard.
  The default keybindings to switch tabs (which are Ctrl+PageUp/-Down and Alt+Home,
  see "Keyboard_Shortcuts_") can be changed using the actions previous_document(),
  next_document() and last_document().

   ----------------------------------------------------------------------

File Format
-----------

  While plain-text is probably the simplest and most interchangeable file
  format in the computer world, there is still variation in what plain-text
  means from system to system.  Plain-text files can differ in character set,
  line termination, and wrapping.

  While character set differences are the most obvious and pose the most
  challenge to portability, they affect NEdit only indirectly via the same font
  and localization mechanisms common to all X applications.  If your system is
  set up properly, you will probably never see character-set related problems
  in NEdit.  NEdit cannot display Unicode text files, nor any multi-byte
  character set.

  The primary difference between an MS DOS format file and a Unix format file,
  is how the lines are terminated.  Unix uses a single newline character.  MS
  DOS uses a carriage-return and a newline.  NEdit can read and write both file
  formats, but internally, it uses the single character Unix standard.  NEdit
  auto-detects MS DOS format files based on the line termination at the start
  of the file.  Files are judged to be DOS format if all of the first five line
  terminators, within a maximum range, are DOS-style.  To change the format in
  which NEdit writes a file from DOS to Unix or visa versa, use the Save As...
  command and check or un-check the MS DOS Format button.

  Wrapping within text files can vary among individual users, as well as from
  system to system.  Both Windows and MacOS make frequent use of plain text
  files with no implicit right margin.  In these files, wrapping is determined
  by the tool which displays them.  Files of this style also exist on Unix
  systems, despite the fact that they are not supported by all Unix utilities.
  To display this kind of file properly in NEdit, you have to select the wrap
  style called Continuous.  Wrapping modes are discussed in the sections:
  Customizing -> Preferences, and Basic Operation -> Shifting and Filling.

  The last and most minute of format differences is the terminating newline.
  Some Unix compilers and utilities require a final terminating newline on all
  files they read and fail in various ways on files which do not have it.  Vi
  and approximately half of Unix editors enforce the terminating newline on all
  files that they write; Emacs does not enforce this rule.  Users are divided
  on which is best.  NEdit makes the final terminating newline optional
  (Preferences -> Default Settings -> Terminate with Line Break on Save).
   ----------------------------------------------------------------------

Features for Programming
========================

Programming with NEdit
----------------------

  Though general in appearance, NEdit has many features intended specifically
  for programmers.  Major programming-related topics are listed in separate
  sections under the heading: "Features for Programming": Syntax_Highlighting_,
  Tabs/Emulated_Tabs_, Finding_Declarations_(ctags)_, Calltips_, and
  Auto/Smart_Indent_.  Minor topics related to programming are discussed below:

3>Language Modes

  When NEdit initially reads a file, it attempts to determine whether the file
  is in one of the computer languages that it knows about.  Knowing what language
  a file is written in allows NEdit to assign highlight patterns and smart indent
  macros, and to set language specific preferences like word delimiters, tab
  emulation, and auto-indent.  Language mode can be recognized from both the file
  name and from the first 200 characters of content.  Language mode recognition
  and language-specific preferences are configured in: Preferences -> Default
  Settings -> Language Modes....

  You can set the language mode manually for a window, by selecting it from the
  menu: Preferences -> Language Modes.

3>Backlighting [EXPERIMENTAL]

  NEdit can be made to set the background color of particular classes of
  characters to allow easy identification of those characters. This is
  particularly useful if you need to be able to distinguish between tabs
  and spaces in a file where the difference is important. The colors used
  for backlighting are specified by a resource, "nedit*backlightCharTypes".
  You can turn backlighting on and off through the
  Preferences -> Apply Backlighting menu entry.

  If you prefer to have backlighting turned on for all new windows, use
  the Preferences -> Default Settings -> Apply Backlighting menu entry.
  This settings can be saved along with other preferences using
  Preferences -> Save Defaults.

  **Important:** In future versions of NEdit, the backlighting feature will be
  extended and reworked such that it becomes easier to configure. The current
  way of controlling it through a resource is generally considered to be below
  NEdit's usability standards. These future changes are likely to be
  incompatible with the current format of the "nedit*backlightCharTypes"
  resource, though. Therefore, it is expected that there will be no automatic
  migration path for users who customize the resource.

3>Line Numbers

  To find a particular line in a source file by line number, choose Goto Line
  #... from the Search menu.  You can also directly select the line number text
  in the compiler message in the terminal emulator window (xterm, decterm,
  winterm, etc.) where you ran the compiler, and choose Goto Selected from the
  Search menu.

  To find out the line number of a particular line in your file, turn on
  Statistics Line in the Preferences menu and position the insertion point
  anywhere on the line.  The statistics line continuously updates the line number
  of the line containing the cursor.

  To go to a specific column on a given line, choose Goto Line #... from the
  Search menu and enter a line number and a column number separated by a
  comma.  (e.g. Enter "100,12" for line 100 column 12.)  If you want to go to
  a column on the current line just leave out the line number.  (e.g. Enter
  ",45" to go the column 45 on the current line.)

3>Matching Parentheses

  To help you inspect nested parentheses, brackets, braces, quotes, and other
  characters, NEdit has both an automatic parenthesis matching mode, and a Goto
  Matching command.  Automatic parenthesis matching is activated when you type,
  or move the insertion cursor after a parenthesis, bracket, or brace.  It
  momentarily highlights either the opposite character ('Delimiter') or the
  entire expression ('Range') when the opposite character is visible in the
  window. To find a matching character anywhere in the file, select it or
  position the cursor after it, and choose Goto Matching from the Search menu.
  If the character matches itself, such as a quote or slash, select the first
  character of the pair.  NEdit will match {, (, [, <, ", ', `, /, and \.
  Holding the Shift key while typing the accelerator key (Shift+Ctrl+M, by
  default), will select all of the text between the matching characters.

  When syntax highlighting is enabled, the matching routines can optionally
  make use of the syntax information for improved accuracy. In that case,
  a brace inside a highlighted string will not match a brace inside a comment,
  for instance.

3>Opening Included Files

  The Open Selected command in the File menu understands the C preprocessor's
  #include syntax, so selecting an #include line and invoking Open Selected will
  generally find the file referred to, unless doing so depends on the settings of
  compiler switches or other information not available to NEdit.

3>Interface to Programming Tools

  Integrated software development environments such as SGI's CaseVision and
  Centerline Software's Code Center, can be interfaced directly with NEdit via
  the client server interface.  These tools allow you to click directly on
  compiler and runtime error messages and request NEdit to open files, and select
  lines of interest.  The easiest method is usually to use the tool's interface
  for character-based editors like vi, to invoke nc, but programmatic interfaces
  can also be derived using the source code for nc.

  There are also some simple compile/review, grep, ctree, and ctags browsers
  available in the NEdit contrib directory on ftp.nedit.org.
   ----------------------------------------------------------------------

Tabs/Emulated Tabs
------------------

3>Changing the Tab Distance

  Tabs are important for programming in languages which use indentation to show
  nesting, as short-hand for producing white-space for leading indents.  As a
  programmer, you have to decide how to use indentation, and how or whether tab
  characters map to your indentation scheme.

  Ideally, tab characters map directly to the amount of indent that you use to
  distinguish nesting levels in your code.  Unfortunately, the Unix standard
  for interpretation of tab characters is eight characters (probably dating
  back to mechanical capabilities of the original teletype), which is usually
  too coarse for a single indent.

  Most text editors, NEdit included, allow you to change the interpretation of
  the tab character, and many programmers take advantage of this, and set their
  tabs to 3 or 4 characters to match their programming style.  In NEdit you set
  the hardware tab distance in Preferences -> Tabs... for the current window,
  or Preferences -> Default Settings -> Tabs... (general), or Preferences ->
  Default Settings -> Language Modes... (language-specific) to change the
  defaults for future windows.

  Changing the meaning of the tab character makes programming much easier while
  you're in the editor, but can cause you headaches outside of the editor,
  because there is no way to pass along the tab setting as part of a plain-text
  file.  All of the other tools which display, print, and otherwise process
  your source code have to be made aware of how the tabs are set, and must be
  able to handle the change.  Non-standard tabs can also confuse other
  programmers, or make editing your code difficult for them if their text
  editors don't support changes in tab distance.

3>Emulated Tabs

  An alternative to changing the interpretation of the tab character is tab
  emulation.  In the Tabs... dialog(s), turning on Emulated Tabs causes the Tab
  key to insert the correct number of spaces and/or tabs to bring the cursor
  the next emulated tab stop, as if tabs were set at the emulated tab distance
  rather than the hardware tab distance. Backspacing immediately after entering
  an emulated tab will delete the fictitious tab as a unit, but as soon as you
  move the cursor away from the spot, NEdit will forget that the collection of
  spaces and tabs is a tab, and will treat it as separate characters.  To enter
  a real tab character with "Emulate Tabs" turned on, use Ctrl+Tab.

  It is also possible to tell NEdit not to insert ANY tab characters at all in
  the course of processing emulated tabs, and in shifting and rectangular
  insertion/deletion operations, for programmers who worry about the
  misinterpretation of tab characters on other systems.

..                             ** NOTE **
..
.. The following Tabs Dialog and Customize Window Title Dialog sections
.. should only appear in the online documentation, and not in any of
.. the other possible forms. The rationale is that they are not directly
.. obtained from the Help menu, but are buried in preference dialogs.
..
.. ? help~
.. Tabs Dialog
.. -----------
..
..   The Tabs dialog controls both the operation of the Tab key, and
..   the interpretation of tab characters within a file.
..   
..   The first field, Tab Spacing, controls how  NEdit responds to
..   tab characters in a file.  On most Unix and VMS systems the
..   conventional interpretation of a tab character is to advance the
..   text position to the nearest multiple of eight characters (a tab
..   spacing of 8).  However, many programmers of C and other
..   structured languages, when given the choice, prefer a tab
..   spacing of 3 or 4 characters.  Setting a three or four character
..   hardware tab spacing is useful and convenient as long as your
..   other software tools support it.  Unfortunately, on Unix and VMS
..   systems, system utilities, such as more, and printing software
..   can't always properly display files with other than eight
..   character tabs.
..   
..   Selecting "Emulate Tabs" will cause the Tab key to insert the
..   correct number of spaces or tabs to reach the next tab stop, as
..   if the tab spacing were set at the value in the "Emulated tab
..   spacing" field.  Backspacing immediately after entering an
..   emulated tab will delete it as a unit, but as soon as you move
..   the cursor away from the spot, NEdit will forget that the
..   collection of spaces and tabs is a tab, and will treat it as
..   separate characters.  To enter a real tab character with
..   "Emulate Tabs" turned on, use Ctrl+Tab.
..   
..   In generating emulated tabs, and in Shift Left, Paste Column,
..   and some rectangular selection operations, NEdit inserts blank
..   characters (spaces or tabs) to preserve the alignment of
..   non-blank characters. The bottom toggle button in the Tabs
..   dialog instructs NEdit whether to insert tab characters as
..   padding in such situations. Turning this off, will keep NEdit
..   from automatically inserting tabs. Some software developers
..   prefer to keep their source code free of tabs to avoid its
..   misinterpretation on systems with different tab character
..   conventions.
..    ----------------------------------------------------------------------
..
.. Customize Window Title Dialog
.. -----------------------------
..
..   The Customize Window Title dialog allows you to customize
..   and test the way information will be displayed in each window's
..   title field.
..   
..   **Definition of the title**
..   
..   The upper half of the dialog can be used to select the various
..   components that should be displayed in the title. The layout can be
..   fine-tuned by editing the printf() like format string below the
..   component buttons: additional characters can be entered, or the
..   order can be changed.
..   
..   The following sequences are interpreted in the format string:
..   
..    %c    ClearCase view tag (only relevant when NEdit is
..          used together with ClearCase)
..    %[n]d directory, with one optional numeric digit n
..          specifying the maximum number of trailing directory
..          components to display. Skipped components are
..          replaced by an ellipsis (...).
..    %f    file name, without the path name
..    %h    host name
..    %s    NEdit server name (server mode only)
..    %[*]S file status, either verbose (%S) or brief (%*S).
..          In verbose mode the file status is spelled out:
..          read-only, locked, and modified. In brief mode,
..          abbreviations and an asterisk are used for the
..          respective states: RO, LO, *.
..    %u    user name
..   
..   The format string and the component buttons are continously synchronized.
..   
..   The default format is:
..   
..     {%c} [%s] %f (%S) - %d
..   
..   The resulting title will only contain elements with
..   a value. Hence, the title is compressed as follows:
..   
..    * Elements with no value are removed.
..    * Empty parenthesis pairs i.e. (), [] or {}, or parenthesis pairs containing only space(s), are removed.
..    * Sequences of spaces are replaced with one space.
..    * Leading spaces and dashes are removed.
..    * Trailing spaces and dashes are removed.
..
..   If the server name and the ClearCase view tag are identical, only
..   the first one specified in the format string will be displayed.
..   
..   **Previewing the settings**
..   
..   The lower part of the dialog can be used to test the selected title
..   under various conditions. For some of the components that are selected
..   for display, various states can be enforced on the preview.
..   
..   For instance, components that are not always active (such the
..   NEdit server name) can be turned on or off in the preview.

.. ~ help

Auto/Smart Indent
-----------------

  Programmers who use structured languages usually require some form of
  automatic indent, so that they don't have to continually re-type the
  sequences of tabs and/or spaces needed to maintain lengthy running indents.
  NEdit therefore offers "smart" indent, in addition to the traditional
  automatic indent which simply lines up the cursor position with the previous
  line.

3>Smart Indent

  Smart indent macros are only available by default for C and C++, and while
  these can easily be configured for different default indentation distances,
  they may not conform to everyone's exact C programming style.  Smart indent
  is programmed in terms of macros in the NEdit macro language which can be
  entered in: Preferences -> Default Settings -> Indent -> Program Smart
  Indent.  Hooks are provided for intervening at the point that a newline is
  entered, either via the user pressing the Enter key, or through
  auto-wrapping; and for arbitrary type-in to act on specific characters typed.

  To type a newline character without invoking smart-indent when operating in
  smart-indent mode, hold the Shift key while pressing the Return or Enter key.

3>Auto-Indent

  With Indent set to Auto (the default), NEdit keeps a running indent.  When
  you press the Return or Enter key, spaces and tabs are inserted to line up
  the insert point under the start of the previous line.

  Regardless of indent-mode, Ctrl+Return always does the automatic indent;
  Shift+Return always does a return without indent.

3>Block Indentation Adjustment

  The Shift Left and Shift Right commands as well as rectangular dragging can
  be used to adjust the indentation for several lines at once.  To shift a
  block of text one character to the right, select the text, then choose Shift
  Right from the Edit menu.  Note that the accelerator keys for these menu
  items are Ctrl+9 and Ctrl+0, which correspond to  the right and left
  parenthesis on most keyboards.  Remember them as adjusting the text in the
  direction pointed to by the parenthesis character.  Holding the Shift key
  while selecting either Shift Left or Shift Right will shift the text by one
  tab stop (or by one emulated tab stop if tab emulation is turned on).  The
  help section "Shifting and Filling" under "Basic Operation" has details.
   ----------------------------------------------------------------------

Syntax Highlighting
-------------------

  Syntax Highlighting means using colors and fonts to help distinguish language
  elements in programming languages and other types of structured files.
  Programmers use syntax highlighting to understand code faster and better, and
  to spot many kinds of syntax errors more quickly.

  To use syntax highlighting in NEdit, select Highlight Syntax in the
  Preferences menu.  If NEdit recognizes the computer language that you are
  using, and highlighting rules (patterns) are available for that language, it
  will highlight your text, and maintain the highlighting, automatically, as
  you type.

  If NEdit doesn't correctly recognize the type of the file you are editing,
  you can manually select a language mode from Language Modes in the
  Preferences menu.  You can also program the method that NEdit uses to
  recognize language modes in Preferences -> Default Settings -> Language
  Modes....

  If no highlighting patterns are available for the language that you want to
  use, you can create new patterns relatively quickly.  The Help section
  "Highlighting_Patterns_" under "Customizing", has details.

  If you are satisfied with what NEdit is highlighting, but would like it to
  use different colors or fonts, you can change these by selecting Preferences
  -> Default Settings -> Syntax Highlighting -> Text Drawing Styles.
  Highlighting patterns are connected with font and color information through a
  common set of styles so that colorings defined for one language will be
  similar across others, and patterns within the same language which are meant
  to appear identical can be changed in the same place.  To understand which
  styles are used to highlight the language you are interested in, you may need
  to look at "Highlighting_Patterns_" section, as well.

  Syntax highlighting is CPU intensive, and under some circumstances can affect
  NEdit's responsiveness.  If you have a particularly slow system, or work with
  very large files, you may not want to use it all of the time.  Syntax
  highlighting introduces two kinds of delays.  The first is an initial parsing
  delay, proportional to the size of the file.  This delay is also incurred
  when pasting large sections of text, filtering text through shell commands,
  and other circumstances involving changes to large amounts of text.  The
  second kind of delay happens when text which has not previously been visible
  is scrolled in to view.  Depending on your system, and the highlight patterns
  you are using, this may or may not be noticeable.  A typing delay is also
  possible, but unlikely if you are only using the built-in patterns.
   ----------------------------------------------------------------------

Finding Declarations (ctags)
----------------------------

  NEdit can process tags files generated using the Unix _ctags command or the
  Exuberant Ctags program.  Ctags creates index files correlating names of
  functions and declarations with their locations in C, Fortran, or Pascal source
  code files. (See the ctags manual page for more information).  Ctags produces a
  file called "tags" which can be loaded by NEdit.  NEdit can manage any number
  of tags files simultaneously.  Tag collisions are handled with a popup menu to
  let the user decide which tag to use.  In 'Smart' mode NEdit will automatically
  choose the desired tag based on the scope of the file or module. Once loaded,
  the information in the tags file enables NEdit to go directly to the
  declaration of a highlighted function or data structure name with a single
  command.  To load a tags file, select "Load Tags File" from the File menu and
  choose a tags file to load, or specify the name of the tags file on the NEdit
  command line:

      nedit -tags tags

  NEdit can also be set to load a tags file automatically when it starts up.
  Setting the X resource nedit.tagFile to the name of a tag file tells NEdit to
  look for that file at startup time (see "Customizing_NEdit_").  The file name
  can be either a complete path name, in which case NEdit will always load the
  same tags file, or a file name without a path or with a relative path, in
  which case NEdit will load it starting from the current directory.  The
  second option allows you to have different tags files for different projects,
  each automatically loaded depending on the directory you're in when you start
  NEdit.  Setting the name to "tags" is an obvious choice since this is the
  name that ctags uses. NEdit normally evaluates relative path tag file
  specifications every time a file is opened. All accessible tag files are
  loaded at this time. To disable the automatic loading of tag files specified
  as relative paths, set the X resource nedit.alwaysCheckRelativeTagsSpecs to
  False.

  To unload a tags file, select "Un-load Tags File" from the File menu and
  choose from the list of tags files.  NEdit will keep track of tags file updates
  by checking the timestamp on the files, and automatically update the tags
  cache.

  To find the definition of a function or data structure once a tags file is
  loaded, select the name anywhere it appears in your program (see
  "Selecting_Text_") and choose "Find Definition" from the Search menu.
   ----------------------------------------------------------------------

Calltips
--------

  Calltips are little yellow boxes that pop up to remind you what the arguments
  and return type of a function are.  More generally, they're a UI mechanism to
  present a small amount of crucial information in a prominent location.  To
  display a calltip, select some text and choose "Show Calltip" from the Search
  menu.  To kill a displayed calltip, hit Esc.

  Calltips get their information from one of two places -- either a tags file (see
  "Finding_Declarations_(ctags)_") or a calltips file.  First, any loaded calltips
  files are searched for a definition, and if nothing is found then the tags
  database is searched.  If a tag is found that matches the highlighted text then
  a calltip is displayed with the first few lines of the definition -- usually
  enough to show you what the arguments of a function are.

  You can load a calltips file by using choosing "Load Calltips File" from the
  File menu.  You can unload a calltips file by selecting it from the
  "Unload Calltips File" submenu of the File menu.  You can also choose one or
  more default calltips files to be loaded for each language mode using the
  "Default calltips file(s)" field of the Language Modes dialog.

  The calltips file format is very simple.  calltips files are organized in blocks
  separated by blank lines.  The first line of the block is the key, which is the
  word that is matched when a calltip is requested.  The rest of the block is
  displayed as the calltip.

  Almost any text at all can appear in a calltip key or a calltip.  There are no
  special characters that need to be escaped.  The only issues to note are that
  trailing whitespace is ignored, and you cannot have a blank line inside a
  calltip.  (Use a single period instead --  it'll be nearly invisible.)  You should
  also avoid calltip keys that begin and end with '@*' characters, since those are
  used to mark special blocks.

  There are five special block types--comment, include, language, alias, and
  version--which are distinguished by their first lines, "@* comment @*",
  "@* include @*", "@* language @*", "@* alias @*", and "@* version @*" respectively
  (without quotes).

  Comment blocks are ignored when reading calltips files.

  Include blocks specify additional calltips files to load, one per line.  The ~
  character can be used for your $HOME directory, but other shell shortcuts like
  @* and ? can't be used. Include blocks allow you to make a calltips file for your
  project that includes, say, the calltips files for C, Motif, and Xt.

  Language blocks specify which language mode the calltips should be used with.
  When a calltip is requested it won't match tips from languages other than the
  current language mode.  Language blocks only affect the tips listed after the
  block.

  Alias blocks allow a calltip to have multiple keys.  The first line of the block
  is the key for the calltip to be displayed, and the rest of the lines are
  additional keys, one per line, that should also show the calltip.

  Version blocks are ignored for the time being.

  You can use calltips in your own macros using the calltip() and kill_calltip()
  macro subroutines and the $calltip_ID macro variable.  See the
  Macro_Subroutines_ section for details.
   ----------------------------------------------------------------------

Regular Expressions
===================

Basic Regular Expression Syntax
-------------------------------

  Regular expressions (regex's) are useful as a way to match inexact sequences
  of characters.  They can be used in the `Find...' and `Replace...' search
  dialogs and are at the core of Color Syntax Highlighting patterns.  To specify
  a regular expression in a search dialog, simply click on the `Regular
  Expression' radio button in the dialog.

  A regex is a specification of a pattern to be matched in the searched text.
  This pattern consists of a sequence of tokens, each being able to match a
  single character or a sequence of characters in the text, or assert that a
  specific position within the text has been reached (the latter is called an
  anchor.)  Tokens (also called atoms) can be modified by adding one of a number
  of special quantifier tokens immediately after the token.  A quantifier token
  specifies how many times the previous token must be matched (see below.)

  Tokens can be grouped together using one of a number of grouping constructs,
  the most common being plain parentheses.  Tokens that are grouped in this way
  are also collectively considered to be a regex atom, since this new larger
  atom may also be modified by a quantifier.

  A regex can also be organized into a list of alternatives by separating each
  alternative with pipe characters, `|'.  This is called alternation.  A match
  will be attempted for each alternative listed, in the order specified, until a
  match results or the list of alternatives is exhausted (see Alternation_
  section below.)

3>The 'Any' Character

  If a dot (`.') appears in a regex, it means to match any character exactly
  once.  By default, dot will not match a newline character, but this behavior
  can be changed (see help topic Parenthetical_Constructs_, under the
  heading, Matching Newlines).

3>Character Classes

  A character class, or range, matches exactly one character of text, but the
  candidates for matching are limited to those specified by the class.  Classes
  come in two flavors as described below:

     [...]   Regular class, match only characters listed.
     [^...]  Negated class, match only characters ~not~ listed.

  As with the dot token, by default negated character classes do not match
  newline, but can be made to do so.

  The characters that are considered special within a class specification are
  different than the rest of regex syntax as follows. If the first character in
  a class is the `]' character (second character if the first character is `^')
  it is a literal character and part of the class character set.  This also
  applies if the first or last character is `-'.  Outside of these rules, two
  characters separated by `-' form a character range which includes all the
  characters between the two characters as well.  For example, `[^f-j]' is the
  same as `[^fghij]' and means to match any character that is not `f', `g',
  `h', `i', or `j'.

3>Anchors

  Anchors are assertions that you are at a very specific position within the
  search text.  NEdit regular expressions support the following anchor tokens:

     ^    Beginning of line
     $    End of line
     <    Left word boundary
     >    Right word boundary
     \B   Not a word boundary

  Note that the \B token ensures that neither the left nor the right character
  are delimiters, **or** that both left and right characters are delimiters.
  The left word anchor checks whether the previous character is a delimiter and
  the next character is not. The right word anchor works in a similar way.

  Note that word delimiters are user-settable, and defined by the X resource
  wordDelimiters, cf. X_Resources_.

3>Quantifiers

  Quantifiers specify how many times the previous regular expression atom may
  be matched in the search text.  Some quantifiers can produce a large
  performance penalty, and can in some instances completely lock up NEdit.  To
  prevent this, avoid nested quantifiers, especially those of the maximal
  matching type (see below.)

  The following quantifiers are maximal matching, or "greedy", in that they
  match as much text as possible (but don't exclude shorter matches if that
  is necessary to achieve an overall match).

     *   Match zero or more
     +   Match one  or more
     ?   Match zero or one

  The following quantifiers are minimal matching, or "lazy", in that they match
  as little text as possible (but don't exclude longer matches if that is
  necessary to achieve an overall match).

     *?   Match zero or more
     +?   Match one  or more
     ??   Match zero or one

  One final quantifier is the counting quantifier, or brace quantifier. It
  takes the following basic form:

     {min,max}  Match from `min' to `max' times the
                previous regular expression atom.

  If `min' is omitted, it is assumed to be zero.  If `max' is omitted, it is
  assumed to be infinity.  Whether specified or assumed, `min' must be less
  than or equal to `max'.  Note that both `min' and `max' are limited to
  65535.  If both are omitted, then the construct is the same as `*'.   Note
  that `{,}' and `{}' are both valid brace constructs.  A single number
  appearing without a comma, e.g. `{3}' is short for the `{min,min}' construct,
  or to match exactly `min' number of times.

  The quantifiers `{1}' and `{1,1}' are accepted by the syntax, but are
  optimized away since they mean to match exactly once, which is redundant
  information.  Also, for efficiency, certain combinations of `min' and `max'
  are converted to either `*', `+', or `?' as follows:

     {} {,} {0,}    *
     {1,}           +
     {,1} {0,1}     ?

  Note that {0} and {0,0} are meaningless and will generate an error message at
  regular expression compile time.

  Brace quantifiers can also be "lazy".  For example {2,5}? would try to match
  2 times if possible, and will only match 3, 4, or 5 times if that is what is
  necessary to achieve an overall match.

3>Alternation

  A series of alternative patterns to match can be specified by separating them
  with vertical pipes, `|'.  An example of _alternation would be `a|be|sea'.
  This will match `a', or `be', or `sea'. Each alternative can be an
  arbitrarily complex regular expression. The alternatives are attempted in
  the order specified.  An empty alternative can be specified if desired, e.g.
  `a|b|'.  Since an empty alternative can match nothingness (the empty string),
  this guarantees that the expression will match.

3>Comments

  Comments are of the form `(?#)' and can be inserted anywhere
  and have no effect on the execution of the regular expression.  They can be
  handy for documenting very complex regular expressions.  Note that a comment
  begins with `(?#' and ends at the first occurrence of an ending parenthesis,
  or the end of the regular expression... period.  Comments do not recognize
  any escape sequences.
   ----------------------------------------------------------------------

Metacharacters
--------------

3>Escaping Metacharacters

  In a regular expression (regex), most ordinary characters match themselves.
  For example, `ab%' would match anywhere `a' followed by `b' followed by `%'
  appeared in the text.  Other characters don't match themselves, but are
  metacharacters. For example, backslash is a special metacharacter which
  'escapes' or changes the meaning of the character following it. Thus, to
  match a literal backslash would require a regular expression to have two
  backslashes in sequence. NEdit provides the following escape sequences so
  that metacharacters that are used by the regex syntax can be specified as
  ordinary characters.

     \(  \)  \-  \[  \]  \<  \>  \{  \}
     \.  \|  \^  \$  \*  \+  \?  \&  \\

3>Special Control Characters

  There are some special characters that are  difficult or impossible to type.
  Many of these characters can be constructed as a sort of metacharacter or
  sequence by preceding a literal character with a backslash. NEdit recognizes
  the following special character sequences:

     \a  alert (bell)
     \b  backspace
     \e  ASCII escape character (***)
     \f  form feed (new page)
     \n  newline
     \r  carriage return
     \t  horizontal tab
     \v  vertical tab

     *** For environments that use the EBCDIC character set,
         when compiling NEdit set the EBCDIC_CHARSET compiler
         symbol to get the EBCDIC equivalent escape
         character.)

3>Octal and Hex Escape Sequences

  Any ASCII (or EBCDIC) character, except null, can be specified by using
  either an octal escape or a hexadecimal escape, each beginning with \0 or \x
  (or \X), respectively.  For example, \052 and \X2A both specify the `*'
  character.  Escapes for null (\00 or \x0) are not valid and will generate an
  error message.  Also, any escape that exceeds \0377 or \xFF will either cause
  an error or have any additional character(s) interpreted literally. For
  example, \0777 will be interpreted as \077 (a `?' character) followed by `7'
  since \0777 is greater than \0377.

  An invalid digit will also end an octal or hexadecimal escape.  For example,
  \091 will cause an error since `9' is not within an octal escape's range of
  allowable digits (0-7) and truncation before the `9' yields \0 which is
  invalid.

3>Shortcut Escape Sequences

  NEdit defines some escape sequences that are handy shortcuts for commonly
  used character classes.

   \d  digits            0-9
   \l  letters           a-z, A-Z, and locale dependent letters
   \s  whitespace        \t, \r, \v, \f, and space
   \w  word characters   letters, digits, and underscore, `_'

  \D, \L, \S, and \W are the same as the lowercase versions except that the
  resulting character class is negated.  For example, \d is equivalent to
  `[0-9]', while \D is equivalent to `[^0-9]'.

  These escape sequences can also be used within a character class.  For
  example, `[\l_]' is the same as `[a-zA-Z@_]', extended with possible locale
  dependent letters. The escape sequences for special characters, and octal
  and hexadecimal escapes are also valid within a class.

3>Word Delimiter Tokens

  Although not strictly a character class, the following escape sequences
  behave similarly to character classes:

     \y   Word delimiter character
     \Y   Not a word delimiter character

  The `\y' token matches any single character that is one of the characters
  that NEdit recognizes as a word delimiter character, while the `\Y' token
  matches any character that is ~not~ a word delimiter character.  Word
  delimiter characters are dynamic in nature, meaning that the user can change
  them through preference settings.  For this reason, they must be handled
  differently by the regular expression engine.  As a consequence of this,
  `\y' and `\Y' cannot be used within a character class specification.
   ----------------------------------------------------------------------

Parenthetical Constructs
------------------------

3>Capturing Parentheses

  Capturing Parentheses are of the form `()' and can be used to group
  arbitrarily complex regular expressions.  Parentheses can be nested, but the
  total number of parentheses, nested or otherwise, is limited to 50 pairs.
  The text that is matched by the regular expression between a matched set of
  parentheses is captured and available for text substitutions and
  backreferences (see below.)  Capturing parentheses carry a fairly high
  overhead both in terms of memory used and execution speed, especially if
  quantified by `*' or `+'.

3>Non-Capturing Parentheses

  Non-Capturing Parentheses are of the form `(?:)' and facilitate
  grouping only and do not incur the overhead of normal capturing parentheses.
  They should not be counted when determining numbers for capturing parentheses
  which are used with backreferences and substitutions.  Because of the limit
  on the number of capturing parentheses allowed in a regex, it is advisable to
  use non-capturing parentheses when possible.

3>Positive Look-Ahead

  Positive look-ahead constructs are of the form `(?=)' and implement a
  zero width assertion of the enclosed regular expression.  In other words, a
  match of the regular expression contained in the positive look-ahead
  construct is attempted.  If it succeeds, control is passed to the next
  regular expression atom, but the text that was consumed by the positive
  look-ahead is first unmatched (backtracked) to the place in the text where
  the positive look-ahead was first encountered.

  One application of positive look-ahead is the manual implementation of a
  first character discrimination optimization.  You can include a positive
  look-ahead that contains a character class which lists every character that
  the following (potentially complex) regular expression could possibly start
  with.  This will quickly filter out match attempts that cannot possibly
  succeed.

3>Negative Look-Ahead

  Negative look-ahead takes the form `(?!)' and is exactly the same as
  positive look-ahead except that the enclosed regular expression must NOT
  match.  This can be particularly useful when you have an expression that is
  general, and you want to exclude some special cases.  Simply precede the
  general expression with a negative look-ahead that covers the special cases
  that need to be filtered out.

3>Positive Look-Behind

  Positive look-behind constructs are of the form `(?<=)' and implement
  a zero width assertion of the enclosed regular expression in front of the
  current matching position.  It is similar to a positive look-ahead assertion,
  except for the fact that the match is attempted on the text preceding the
  current position, possibly even in front of the start of the matching range
  of the entire regular expression.

  A restriction on look-behind expressions is the fact that the expression
  must match a string of a bounded size.  In other words, `*', `+', and `{n,}'
  quantifiers are not allowed inside the look-behind expression. Moreover,
  matching performance is sensitive to the difference between the upper and
  lower bound on the matching size.  The smaller the difference, the better the
  performance.  This is especially important for regular expressions used in
  highlight patterns.

  Positive look-behind has similar applications as positive look-ahead.

3>Negative Look-Behind

  Negative look-behind takes the form `(?)' and is exactly the same as
  positive look-behind except that the enclosed regular expression must
  ~not~ match. The same restrictions apply.

  Note however, that performance is even more sensitive to the distance
  between the size boundaries: a negative look-behind must not match for
  **any** possible size, so the matching engine must check **every** size.

3>Case Sensitivity

  There are two parenthetical constructs that control case sensitivity:

     (?i)   Case insensitive; `AbcD' and `aBCd' are
                   equivalent.

     (?I)   Case sensitive;   `AbcD' and `aBCd' are
                   different.

  Regular expressions are case sensitive by default, that is, `(?I)' is
  assumed.  All regular expression token types respond appropriately to case
  insensitivity including character classes and backreferences.  There is some
  extra overhead involved when case insensitivity is in effect, but only to the
  extent of converting each character compared to lower case.

3>Matching Newlines

  NEdit regular expressions by default handle the matching of newlines in a way
  that should seem natural for most editing tasks.  There are situations,
  however, that require finer control over how newlines are matched by some
  regular expression tokens.

  By default, NEdit regular expressions will ~not~ match a newline character for
  the following regex tokens: dot (`.'); a negated character class (`[^...]');
  and the following shortcuts for character classes:

     `\d', `\D', `\l', `\L', `\s', `\S', `\w', `\W', `\Y'

  The matching of newlines can be controlled for the `.' token, negated
  character classes, and the `\s' and `\S' shortcuts by using one of the
  following parenthetical constructs:

     (?n)  `.', `[^...]', `\s', `\S' match newlines

     (?N)  `.', `[^...]', `\s', `\S' don't match
                                            newlines

  `(?N)' is the default behavior.

3>Notes on New Parenthetical Constructs

  Except for plain parentheses, none of the parenthetical constructs capture
  text.  If that is desired, the construct must be wrapped with capturing
  parentheses, e.g. `((?iBack References

  Backreferences allow you to match text captured by a set of capturing
  parenthesis at some later position in your regular expression.  A
  backreference is specified using a single backslash followed by a single
  digit from 1 to 9 (example: \3).  Backreferences have similar syntax to
  substitutions (see below), but are different from substitutions in that they
  appear within the regular expression, not the substitution string. The number
  specified with a backreference identifies which set of text capturing
  parentheses the backreference is associated with. The text that was most
  recently captured by these parentheses is used by the backreference to
  attempt a match.  As with substitutions, open parentheses are counted from
  left to right beginning with 1.  So the backreference `\3' will try to match
  another occurrence of the text most recently matched by the third set of
  capturing parentheses.  As an example, the regular expression `(\d)\1' could
  match `22', `33', or `00', but wouldn't match `19' or `01'.

  A backreference must be associated with a parenthetical expression that is
  complete.  The expression `(\w(\1))' contains an invalid backreference since
  the first set of parentheses are not complete at the point where the
  backreference appears.

3>Substitution

  Substitution strings are used to replace text matched by a set of capturing
  parentheses.  The substitution string is mostly interpreted as ordinary text
  except as follows.

  The escape sequences described above for special characters, and octal and
  hexadecimal escapes are treated the same way by a substitution string. When
  the substitution string contains the `&' character, NEdit will substitute the
  entire string that was matched by the `Find...' operation. Any of the first
  nine sub-expressions of the match string can also be inserted into the
  replacement string.  This is done by inserting a `\' followed by a digit from
  1 to 9 that represents the string matched by a parenthesized expression
  within the regular expression.  These expressions are numbered left-to-right
  in order of their opening parentheses.

  The capitalization of text inserted by `&' or `\1', `\2', ... `\9' can be
  altered by preceding them with `\U', `\u', `\L', or `\l'.  `\u' and `\l'
  change only the first character of the inserted entity, while `\U' and `\L'
  change the entire entity to upper or lower case, respectively.
   ----------------------------------------------------------------------

Advanced Topics
---------------

3>Substitutions

  Regular expression substitution can be used to program automatic editing
  operations.  For example, the following are search and replace strings to find
  occurrences of the `C' language subroutine `get_x', reverse the first and
  second parameters, add a third parameter of NULL, and change the name to
  `new_get_x':

     Search string:   `get_x *\( *([^ ,]*), *([^\)]*)\)'
     Replace string:  `new_get_x(\2, \1, NULL)'

3>Ambiguity

  If a regular expression could match two different parts of the text, it will
  match the one which begins earliest.  If both begin in the same place but
  match different lengths, or match the same length in different ways, life
  gets messier, as follows.

  In general, the possibilities in a list of alternatives are considered in
  left-to-right order.  The possibilities for `*', `+', and `?' are considered
  longest-first, nested constructs are considered from the outermost in, and
  concatenated constructs are considered leftmost-first. The match that will be
  chosen is the one that uses the earliest possibility in the first choice that
  has to be made.  If there is more than one choice, the next will be made in
  the same manner (earliest possibility) subject to the decision on the first
  choice.  And so forth.

  For example, `(ab|a)b*c' could match `abc' in one of two ways.  The first
  choice is between `ab' and `a'; since `ab' is earlier, and does lead to a
  successful overall match, it is chosen.  Since the `b' is already spoken for,
  the `b*' must match its last possibility, the empty string, since it must
  respect the earlier choice.

  In the particular case where no `|'s are present and there is only one `*',
  `+', or `?', the net effect is that the longest possible match will be
  chosen.  So `ab*', presented with `xabbbby', will match `abbbb'.  Note that
  if `ab*' is tried against `xabyabbbz', it will match `ab' just after `x', due
  to the begins-earliest rule.  (In effect, the decision on where to start the
  match is the first choice to be made, hence subsequent choices must respect
  it even if this leads them to less-preferred alternatives.)

Macro/Shell Extensions
======================

Shell Commands and Filters
--------------------------

  The Shell menu (Unix versions only) allows you to execute Unix shell commands
  from within NEdit.  You can add items to the menu to extend NEdit's command
  set or to incorporate custom automatic editing features using shell commands
  or editing languages like awk and sed.  To add items to the menu, select
  Preferences -> Default Settings Customize Menus -> Shell Menu.  NEdit comes
  pre-configured with a few useful Unix commands like spell and sort, but we
  encourage you to add your own custom extensions.

  Filter Selection... prompts you for a Unix command to use to process the
  currently selected text.  The output from this command replaces the contents
  of the selection.

  Execute Command... prompts you for a Unix command and replaces the current
  selection with the output of the command.  If there is no  selection, it
  deposits the output at the current insertion point. In the Shell Command
  field, the % character expands to the name (including directory path), and
  the # character expands to the current line number of the file in the window.
  To include a % or # character in the command, use %% or ##, respectively.

  Execute Command Line uses the position of the cursor in the window to
  indicate a line to execute as a shell command line.  The cursor may be
  positioned anywhere on the line.  This command allows you to use an NEdit
  window as an editable command window for saving output and saving commands
  for re-execution. Note that the same character expansions described above
  in Execute Command also occur with this command.

  The X resource called nedit.shell (See "Customizing_NEdit_") determines which
  Unix shell is used to execute commands.  The default value for this resource
  is the user's login shell.
   ----------------------------------------------------------------------

Learn/Replay
------------

  Selecting Learn Keystrokes from the Macro menu puts NEdit in learn mode.  In
  learn mode, keystrokes and menu commands are recorded, to be played back
  later, using the Replay Keystrokes command, or pasted into a macro in the
  Macro Commands dialog of the Default Settings menu in Preferences.

  Note that only keyboard and menu commands are recorded, not mouse clicks or
  mouse movements since these have no absolute point of reference, such as
  cursor or selection position.  When you do a mouse-based operation in learn
  mode, NEdit will beep (repeatedly) to remind you that the operation was not
  recorded.

  Learn mode is also the quickest and easiest method for writing macros.  The
  dialog for creating macro commands contains a button labeled "Paste Learn /
  Replay Macro", which will deposit the last sequence learned into the body of
  the macro.

3>Repeating Actions and Learn/Replay Sequences

  You can repeat the last (keyboard-based) command, or learn/replay sequence
  with the Repeat... command in the Macro menu.  To repeat an action, first do
  the action (that is, insert a character, do a search, move the cursor), then
  select Repeat..., decide how or how many times you want it repeated, and
  click OK.  For example, to move down 30 lines through a file, you could type:
   Ctrl+, 29 .  To repeat a learn/replay sequence, first
  learn it, then select Repeat..., click on Learn/Replay and how you want it
  repeated, then click OK.

  If the commands you are repeating advance the cursor through the file, you
  can also repeat them within a range of characters, or from the current cursor
  position to the end of the file.  To iterate over a range of characters, use
  the primary selection (drag the left mouse button over the text) to mark the
  range you want to operate on, and select "In Selection" in the Repeat dialog.

  When using In "Selection" or "To End" with a learned sequence, try to do
  cursor movement as the last step in the sequence, since testing of the cursor
  position is only done at the end of the sequence execution.  If you do cursor
  movement first, for example searching for a particular word then doing a
  modification, the position of the cursor won't be checked until the sequence
  has potentially gone far beyond the end of your desired range.

  It's easy for a repeated command to get out of hand, and you can easily
  generate an infinite loop by using range iteration on a command which doesn't
  progress.  To cancel a repeating command in progress, type Ctrl+. (period),
  or select Cancel Macro from the Macro menu.
   ----------------------------------------------------------------------

Macro Language
--------------

  Macros can be called from Macro menu commands, window background menu
  commands, within the smart-indent framework, from the autoload macro file,
  cf. Preferences_, and from the command line.
  Macro menu and window background menu commands are defined under Preferences
  -> Default Settings -> Customize Menus.  Help on creating items in these
  menus can be found in the section Preferences_.

  NEdit's macro language is a simple interpreter with integer arithmetic,
  dynamic strings, and C-style looping constructs (very similar to the
  procedural portion of the Unix awk program).  From the macro language, you
  can call the same action routines which are bound to keyboard keys and menu
  items, as well additional subroutines for accessing and manipulating editor
  data, which are specific to the macro language (these are listed in the
  sections titled "Macro_Subroutines_", and "Action_Routines_").


3>Syntax

  An NEdit macro language program consists of a list of statements, each
  terminated by a newline.  Groups of statements which are executed together
  conditionally, such as the body of a loop, are surrounded by curly braces
  "{}".

  Blank lines and comments are also allowed.  Comments begin with a "#" and end
  with a newline, and can appear either on a line by themselves, or at the end
  of a statement.

  Statements which are too long to fit on a single line may be split across
  several lines, by placing a backslash "\" character at the end of each line
  to be continued.


3>Data Types

  The NEdit macro language recognizes only three data types, dynamic character
  strings, integer values and associative arrays. In general strings and
  integers can be used interchangeably. If a string represents an integer
  value, it can be used as an integer. Integers can be compared and
  concatenated with strings. Arrays may contain integers, strings, or arrays.
  Arrays are stored key/value pairs. Keys are always stored as strings.

4>Integer Constants

  Integers are non-fractional numbers in the range of -2147483647 to
  2147483647.  Integer constants must be in decimal.  For example:

    a = -1
    b = 1000

4>Character String Constants

  Character string constants are enclosed in double quotes.  For example:

     a = "a string"
     dialog("Hi there!", "OK")

  Strings may also include C-language style escape sequences:

     \\ Backslash     \t Tab              \f Form feed
     \" Double quote  \b Backspace        \a Alert
     \n Newline       \r Carriage return  \v Vertical tab

  Also allowed is the escape control character sequence:

     \e Escape (ASCII or EBCDIC,
                depending on NEdit compilation settings)

  For example, to send output to the terminal from which NEdit was started, a
  newline character is necessary because, like printf, t_print requires
  explicit newlines, and also buffers its output on a per-line basis:

     t_print("a = " a "\n")

  Other characters can be expressed as backslash-escape sequences in macro
  strings. The format is the same as for regular expressions, described in the
  paragraphs headed "Octal and Hex Escape Sequences" of the section
  "Metacharacters_", except that an octal escape sequence can start with any
  octal digit, not just 0, so the single character string "\0033" is the same
  as "\33", "\x1B" and "\e" (for an ASCII version of NEdit).

  Note that if you want to define a regular expression in a macro string,
  you need to "double-up" the backslashes for the metacharacters with
  special meaning in regular expressions. For example, the expression

     (?N(\s|/\*(?n(?:(?!\*/).)*)\*/|//.*\n|\n)+)

  which matches whitespace or C/C++/Java-style comments, should be written as
  a macro string as

     "(?N(\\s|/\\*(?n(?:(?!\\*/).)*)\\*/|//.*\n|\n)+)"

  (The "\n"s towards the end add literal newline characters to the string. The
  regular expression interpretation treats the newlines as themselves. It can
  also interpret the sequence "\\n" as a newline, although the macro string here
  would then contain a literal backslash followed by a lowercase `N'.)


3>Variables

  Variable names must begin either with a letter (local variables), or a $
  (global variables).  Beyond the first character, variables may also contain
  numbers and underscores `_'.  Variables are called in to existence just by
  setting them (no explicit declarations are necessary).

  Local variables are limited in scope to the subroutine (or menu item
  definition) in which they appear.  Global variables are accessible from all
  routines, and their values persist beyond the call which created them, until
  reset.

4>Built-in Variables

  NEdit has a number of permanently defined variables, which are used to access
  global editor information and information about the window in which the
  macro is executing.  These are listed along with the built in functions in
  the section titled "Macro_Subroutines_".


3>Functions and Subroutines

  The syntax of a function or subroutine call is:

     function_name(arg1, arg2, ...)

  where arg1, arg2, etc. represent the argument values which are passed to
  the routine being called.  A function or subroutine call can be on a line by
  itself, as above, or if it returns a value, can be invoked within a character
  or numeric expression:

     a = fn1(b, c) + fn2(d)
     dialog("fn3 says: " fn3())

  Arguments are passed by value.  This means that you cannot return values via
  the argument list, only through the function value or indirectly through
  agreed-upon global variables.

4>Built-in Functions

  NEdit has a wide range of built in functions which can be called from the
  macro language.  These routines are divided into two classes, macro-language
  functions, and editor action routines.  Editor action routines are more
  flexible, in that they may be called either from the macro language, or bound
  directly to keys via translation tables.  They are also limited, however, in
  that they cannot return values.  Macro language routines can return values,
  but cannot be bound to keys in translation tables.

  Nearly all of the built-in subroutines operate on an implied window, which is
  initially the window from which the macro was started.  To manipulate the
  contents of other windows, use the focus_window subroutine to change the
  focus to the ones you wish to modify.  focus_window can also be used to
  iterate over all of the currently open windows, using the special keyword
  names, "last" and "next".

  For backwards compatibility, hyphenated action routine names are allowed, and
  most of the existing action routines names which contain underscores have an
  equivalent version containing hyphens ('-') instead of underscores.  Use of
  these names is discouraged.  The macro parser resolves the ambiguity between
  '-' as the subtraction/negation operator, and - as part of an action routine
  name by assuming subtraction unless the symbol specifically matches an action
  routine name.

4>User Defined Functions

  Users can define their own macro subroutines, using the define keyword:

     define subroutine_name {
        < body of subroutine >
     }

  Subroutine definitions cannot appear within other definitions, nor within
  macro menu item definitions.  They can only appear in (macro) files, such as
  the autoload macro file, cf. Preferences_. Macro files can be loaded with
  File -> Load Macro File or with the load_macro_file() action.

  The arguments with which a user-defined subroutine or function was invoked,
  are presented as $1, $2, ... , $9 or $args[expr], where expr can be evaluated
  to an integer from 1 to the number of arguments.  The number of arguments can
  be read from $n_args or $args[]. The array $args[expr] is the only way to
  access arguments beyond the first 9.

  To return a value from a subroutine, and/or to exit from the subroutine
  before the end of the subroutine body, use the return statement:

     return 


3>Operators and Expressions

  Operators have the same meaning and precedence that they do in C, except for
  ^, which raises a number to a power (y^x means y to the x power), rather than
  bitwise exclusive OR.  The table below lists operators in decreasing order of
  precedence.

     Operators                Associativity
     ()
     ^                        right to left
     - ! ++ --                (unary)
     * / %                    left to right
     + -                      left to right
     > >= < <= == !=          left to right
     &                        left to right
     |                        left to right
     &&                       left to right
     ||                       left to right
     (concatenation)          left to right
     = += -= *= /= %=, &= |=  right to left

  The order in which operands are evaluated in an expression is undefined,
  except for && and ||, which like C, evaluate operands left to right, but stop
  when further evaluation would no longer change the result.

4>Numerical Operators

  The numeric operators supported by the NEdit macro language are listed below:

     + addition
     - subtraction or negation
     * multiplication
     / division
     % modulo
     ^ power
     & bitwise and
     | bitwise or

  Increment (++) and decrement (--) operators can also be appended or prepended
  to variables within an expression.  Prepended increment/decrement operators
  act before the variable is evaluated.  Appended increment/decrement operators
  act after the variable is evaluated.

4>Logical and Comparison Operators

  Logical operations produce a result of 0 (for false) or 1 (for true).  In a
  logical operation, any non-zero value is recognized to mean true.  The
  logical and comparison operators allowed in the NEdit macro language are
  listed below:

     && logical and
     || logical or
     !  not
     >  greater
     <  less
     >= greater or equal
     <= less or equal
     == equal (integers and/or strings)
     != not equal (integers and/or strings)

4>Character String Operators

  The "operator" for concatenating two strings is the absence of an operator.
  Adjoining character strings with no operator in between means concatenation:

     d = a b "string" c
     t_print("the value of a is: " a)

  Comparison between character strings is done with the == and != operators,
  (as with integers).  There are a number of useful built-in routines for
  working with character strings, which are listed in the section called
  "Macro_Subroutines_".

4>Arrays and Array Operators

  Arrays may contain either strings, integers, or other arrays. Arrays are
  associative, which means that they relate two pieces of information, the key
  and  the value. The key is always a string; if you use an integer it is
  converted to a string.

  To determine if a given key is in an array, use the 'in' keyword.

      if ("6" in x)
          

  If the left side of the in keyword is an array, the result is true if every
  key in the left array is in the right array. Array values are not compared.

  To iterate through all the keys of an array use the 'for' looping construct.
  Keys are not guaranteed in any particular order:

      for (aKey in x)
          

  Elements can be removed from an array using the delete command:

      delete x[3] # deletes element with key 3
      delete x[]  # deletes all elements

  The number of elements in an array can be determined by referencing the
  array with no indices:

      dialog("array x has " x[] " elements", "OK")

  Arrays can be combined with some operators. All the following operators only
  compare the keys of the arrays.

      result = x + y   (Merge arrays)

  The 'result' is a new array containing keys from both x and y. If
  duplicates are present values from y are used.

      result = x - y   (Remove keys)

  The 'result' is a new array containing all keys from x that are not in y.

      result = x & y   (Common keys)

  The 'result' is a new array containing all keys which are in both x and y.
  The values from y are used.

      result = x | y   (Unique keys)

  The 'result' is a new array containing keys which exist in either x or y,
  but not both.

  When duplicate keys are encountered using the + and & operators, the values
  from the array on the right side of the operators are used for the result.
  All  of the above operators are array only, meaning both the left and right
  sides of the operator must be arrays. The results are also arrays.

  Array keys can also contain multiple dimensions:

      x[1, 1, 1] = "string"

  These are used in the expected way, e.g.:

      for (i = 1; i < 3; i++)
      {
          for (j = 1; j < 3; j++)
          {
              x[i, j] = k++
          }
      }

  gives the following array:

      x[1, 1] = 0
      x[1, 2] = 1
      x[2, 1] = 2
      x[2, 2] = 3

  Internally all indices are part of one string, separated by the string
  $sub_sep (ASCII 0x1c, 'FS'). The first key in the above example is in
  fact:

      ["1" $sub_sep "1"]

  If you need to extract one of the keys, you can use split(), using
  $sub_sep as the separator.

  You can also check for the existence of multi-dimensional array by
  looking for $sub_sep in the key.

  Last, you need $sub_sep if you want to use the 'in' keyword.

      if ((1,2) in myArray)
      {..}

  doesn't work, but

      if (("1" $sub_sep "2") in myArray)
      {..}

  does work.

3>Looping and Conditionals

  NEdit supports looping constructs: for and while, and conditional statements:
  if and else, with essentially the same syntax as C:

     for (, ...; ; , ...) 

     while () 

     if () 

     if ()  else 

  , as in C, can be a single statement, or a list of statements enclosed
  in curly braces ({}).   is an expression which must evaluate to
  true for the statements in  to be executed.  for loops may also contain
  initialization statements, , executed once at the beginning of the
  loop, and increment/decrement statements (or any arbitrary statement), which
  are executed at the end of the loop, before the condition is evaluated again.

  Examples:

    for (i=0; i<100; i++)
       j = i * 2

    for (i=0, j=20; i<20; i++, j--) {
       k = i * j
       t_print(i, j, k)
    }

    while (k > 0)
    {
       k = k - 1
       t_print(k)
    }

    for (;;) {
       if (i-- < 1)
           break
    }

  Loops may contain break and continue statements.  A **break** statement
  causes an exit from the innermost loop, a **continue** statement transfers
  control to the end of the loop.

3>Built-in Subroutines

**append_file( string, filename )**
  Appends a string to a named file. Returns 1 on successful write, or 0 if
  unsuccessful.

**beep()**
  Ring the bell.

**calltip( "text_or_key" [, pos [, mode or position_modifier, ...]] )**
  Pops up a calltip.  is an optional position in the buffer where the tip
  will be displayed. Passing -1 for  is equivalent to not specifying a
  position, and it guarantees that the tip will appear on-screen somewhere even
  if the cursor is not. The upper-left corner of the calltip will appear below
  where the cursor would appear if it were at this position.

   is one of "tipText" (default), "tipKey", or "tagKey". "tipText"
  displays the text as-is, "tagKey" uses it as the key to look up a tag, then
  converts the tag to a calltip, and "tipKey" uses it as the key to look up a
  calltip, then falls back to "tagKey" behavior if that fails. You'll usually
  use "tipKey" or "tipText".

  Finally, you can modify the placement of the calltip relative to the cursor
  position (or ) with one or more of these optional position modifiers:
  "center" aligns the center of the calltip with the position. "right" aligns
  the right edge of the calltip with the position. ("center" and "right" may
  not both be used.) "above" places the calltip above the position. "strict"
  does not allow the calltip to move from its position in order to avoid going
  off-screen or obscuring the cursor.

  Returns the ID of the calltip if it was found and/or displayed correctly,
  0 otherwise.

**clipboard_to_string()**
  Returns the contents of the clipboard as a macro string. Returns empty
  string on error.

**dialog( message, btn_1_label, btn_2_label, ... )**
  Pop up a dialog for querying and presenting information to the user. First
  argument is a string to show in the message area of the dialog.
  Additional optional arguments represent labels for buttons to appear along
  the bottom of the dialog. Returns the number of the button pressed (the
  first button is number 1), or 0 if the user closed the dialog via the window
  close box.

**filename_dialog( [title[, mode[, defaultPath[, filter[, defaultName]]]]] )**
  Presents a file selection dialog with the given title to the user that 
  prompts for a new or existing file.

  Options are: ~title~ will be the title of the dialog, defaults to "Choose
  file". If ~mode~ is set to "exist" (default), the "New File Name"TextField
  of the FSB will be unmanaged. If "new", the TextField will be managed.
  ~defaultPath~ is the default path to use. Default (or "") will use the
  active document's directory. ~filter~ is the file glob which determines
  which files to display. Is set to "*" if filter is "" and by default.
  ~defaultName~ is the default filename that is filled in automatically.
  (**Note** that the default_filename argument does not work on all Motif
  implementations.)

  Returns "" if the user cancelled the dialog, otherwise returns the
  fully-qualified path, including the filename.

**focus_window( window_name )**  
  Sets the window on which subsequent macro commands operate. window_name can
  be either a fully qualified file name, or a relative filename (which will
  be completed from NEdit's working directory) or one of "last" for the last
  window created, or "next" for the next window in the chain from the currently
  focused window (the first window being the one returned from calling
  focus_window("last"). Returns the name of the newly-focused window, or an
  empty string if the requested window was not found.

**get_character( position )**
  Returns the single character at the position
  indicated by the first argument to the routine from the current window.

**get_range( start, end )**
  Returns the text between a starting and ending position from the current
  window.

**get_selection()**
  Returns a string containing the text currently selected by the primary
  selection either from the current window (no keyword), or from anywhere on
  the screen (keyword "any").

**getenv( name )**
  Gets the value of an environment variable.

**kill_calltip( [calltip_ID] )**
  Kills any calltip that is being displayed in the window in which the macro is
  running.  If there is no displayed calltip this does nothing.  If a calltip
  ID is supplied then the calltip is killed only if its ID is calltip_ID.

**length( string )**
  Returns the length of a string

**list_dialog( message, text, btn_1_label, btn_2_label, ... )**
  Pop up a dialog for prompting the user to choose a line from the given text
  string. The first argument is a message string to be used as a title for the
  fixed text describing the list. The second string provides the list data:
  this is a text string in which list entries are separated by newline
  characters. Additional optional arguments represent labels for
  buttons to appear along the bottom of the dialog. Returns the line of text
  selected by the user as the function value (without any newline separator) or
  the empty string if none was selected, and number of the button pressed (the
  first button is number 1), in $list_dialog_button. If the user closes the
  dialog via the window close box, the function returns the empty string, and
  $list_dialog_button returns 0.

**max( n1, n2, ... )**
  Returns the maximum value of all of its arguments

**min( n1, n2, ... )**
  Returns the minimum value of all of its arguments

**read_file( filename )**  
  Reads the contents of a text file into a string. On success, returns 1 in
  $read_status, and the contents of the file as a string in the subroutine
  return value. On failure, returns the empty string "" and an 0 $read_status.

**replace_in_string( string, search_for, replace_with [, type, "copy"] )**
  Replaces all occurrences of a search string in a string with a replacement
  string. Arguments are 1: string to search in, 2: string to search for, 3:
  replacement string.  There are two optional arguments.  One is a search type,
  either "literal", "case", "word", "caseWord", "regex", or "regexNoCase".
  The default search type is "literal".  If the optional "copy" argument is
  specified, a copy of the input string is returned when no replacements were
  performed.  By default an empty string ("") will be returned in this case.
  Returns a new string with all of the replacements done.

**replace_range( start, end, string )**
  Replaces all the text between two positions in the current window. If the
  cursor position is between start and end it will be set to start.

**replace_selection( string )**
  Replaces the primary-selection selected text in the current window.

**replace_substring( string, start, end, replace_with )**
  Replacing a substring between two positions in a string within another string.

  since the last save.

**search( search_for, start [, search_type, wrap, direction] )**
  Searches silently in a window without dialogs, beeps, or changes to the
  selection. Arguments are: 1: string to search for, 2: starting position.
  Optional arguments may include the strings: "wrap" to make the search wrap
  around the beginning or end of the string, "backward" or "forward" to change
  the search direction ("forward" is the default), "literal", "case", "word",
  "caseWord", "regex", or "regexNoCase" to change the search  type  (default is
  "literal"). Returns the starting position of the  match, or -1 if nothing
  matched. Also returns the ending position  of the match in $search_end.

**search_string( string, search_for, start [, search_type, direction] )**
  Built-in macro subroutine for searching a string. Arguments are 1: string to
  search in, 2: string to search for, 3: starting position. Optional arguments
  may include the strings: "wrap" to make the search wrap around the beginning
  or end of the string, "backward" or "forward" to change the search direction
  ("forward" is the default), "literal", "case", "word", "caseWord", "regex",
  or "regexNoCase" to change the search type (default is "literal"). Returns
  the starting position of the match, or -1 if nothing matched. Also returns
  the ending position of the match in $search_end.

**select( start, end )**
  Selects (with the primary selection) text in the current buffer between a
  starting and ending position.

**select_rectangle( start, end, left, right )**

..  nedit*backlightCharTypes X resource, to the current text window, turning on
..  backlighting.  If the value of the string passed is "default", or if no
..  parameter is passed, the nedit.backlightCharTypes X resource's own value will
..  be used.  If the empty string, "", is passed, backlighting will be turned
..  off.

**set_cursor_pos( position )**
  Set the cursor position for the current window.

**shell_command( command, input_string )**
  Executes a shell command, feeding it input from input_string. On completion,
  output from the command is returned as the function value, and the command's
  exit status is returned in the global variable $shell_cmd_status.

**split(string, separation_string [, search_type])**
  Splits a string using the separator specified. Optionally the search_type
  argument can specify how the separation_string is interpreted. The default
  is "literal". The returned value is an array with keys beginning at 0.

**string_dialog( message, btn_1_label, btn_2_label, ... )**
  Pops up a dialog prompting the user to enter information. The first argument
  is a string to show in the message area of the dialog. Additional
  optional arguments represent labels for buttons to appear along the bottom of
  the dialog. Returns the string entered by the user as the function value,
  and number of the button pressed (the first button is number 1), in
  $string_dialog_button. If the user closes the dialog via the window close
  box, the function returns the empty string, and $string_dialog_button returns
  0.

**string_compare(string1, string2 [, consider-case])**
  Compare two  strings and return 0 if they are equal, -1 if string1 is less
  than  string2 or 1 if string1 is greater than string2. The values for the
  optional consider-case argument is either "case" or "nocase". The default
  is to do a case sensitive comparison.

**string_to_clipboard( string )**
  Copy the contents of a macro string to the clipboard.

**substring( string, start [, end] )**
  Returns the portion of a string between a start and end position (with the
  position of the beginning of the string being 0).  If end is missing, the
  position of the end of the string is used. If either of the positions are
  negative, they are treated as relative to the end of the string.  A position
  specified either before the start of the string or after the end of the string
  is repositioned to the nearest valid string position.  If the start position
  is beyond the end position, the empty string is returned.

**t_print( string1, string2, ... )**
  Writes strings to the terminal (stdout) from which NEdit was started.

**tolower( string )**
  Return an all lower-case version of string.

**toupper( string )**

**valid_number( string )**
  Returns 1 if the string can be converted to a number without error
  following the same rules that the implicit conversion would. Otherwise 0.

**write_file( string, filename )**

  Some functions are included only for supporting legacy macros. You should not
  use any of these functions in any new macro you write. Among these are all
  action routines with hyphens in their names; use underscores instead
  ('find-dialog' -> 'find_dialog').

**match()**
  **DEPRECATED** Use select_to_matching() instead.

   ----------------------------------------------------------------------

Rangesets
----------

  Rangesets are a tool of the macro language to tag parts, or ranges, of the
  text, which shall be viewed as a group. A range is merely a contiguous range
  of characters between a start and an end position in the document, and a set
  of ranges belonging together is called a rangeset. So, a rangeset is nothing
  but an in general non-contiguous part of the text.

  Rangesets can be assigned a background color to make them visible: characters
  within all ranges of a rangeset will have the background color of the
  rangeset. (If more than one rangeset includes a given character, its
  background color will be that of the most recently created rangeset which has
  a color defined.)

  Applications of rangesets are for example:

* Showing differences between two versions of a file. Then, one rangeset would be those parts of the current file that are not in the prior version.
* Highlighting all occurrences of a particular pattern, e.g. showing all the strings 'foobar' in the file.
* Highlighting spelling mistakes found by a spell-checker.

  Rangesets are manipulated only through macro routines. Rangesets must be
  created first using the rangeset_create() function, which will return an
  identifier for the newly-created (empty) rangeset. This identifier is then
  passed to the other rangeset functions to manipulate the rangeset. For
  example, ranges are added to a rangeset with the rangeset_add() function.

  Notice that the ranges inside a rangeset do not have a particular identity.
  Only, they are given a (dynamically changing) numeric index, counting from 1,
  in the order of appearance in the text buffer. The ranges are adjusted when
  modifications are made to the text buffer: they shift around when characters
  are added or deleted staying with the original strings of characters.
  However, ranges within a set will coalesce if the characters between them are
  removed, or a new range is added to  the set which bridges or overlaps
  others. For more on this, see "How rangesets change with modifications".

  There is a limit to the number of rangesets which can exist at any time -
  currently up to 63 in each document. Care should be taken to destroy any
  rangesets which are no longer needed, by using the rangeset_destroy()
  function, if this limit is attained.

  Rangesets can be named: this is useful for macros which need a fixed
  identification for rangesets which are used for the same purpose in different
  documents. Although a new rangeset's number is arbitrary, its name can be
  fixed.  This is done using the rangeset_set_name() function. Note that
  rangeset names within a particular document may not be unique. For this
  reason, the rangeset_get_by_name() function returns an array of identifiers,
  which will be empty if the name has not been associated with a rangeset.

4>How rangesets change with modifications

  When changes are made to the document text, ranges within each set are altered
  with it, according to their behavioral mode.  If changes are made outside of
  the ranges in a rangeset, each range simply maintains its size and adjusts its
  position to match the changes.  When text within a range is deleted, the
  range's length is reduced by the same amount. When changes involving new text
  are made within a range of the set, or to one of the extremities of a range,
  different behaviours may be desirable. The rangeset_set_mode() function allows
  these modes to be chosen.

  Note that the precise behaviour of these modes may change in future versions
  of NEdit.

  The available modes are:

  **maintain** or **ins_del** -
  Both these modes have the same behaviour.  New text added at the front of a
  range in a set is not added to the range; new text added within the range or
  at the end extends the range.  Replacement overlapping an extremity of the
  set acts as if the new text were added first, then the old text deleted.
  This causes curtailment at the front of the range, extension at the end.
  Replacement of the full text of the range removes the range from the set.
  The default behaviour for a newly created rangeset is **maintain**.

  **del_ins** -
  New text added at the front or end of a range in a set is not added to the
  range; new text added within the range extends the range.  Replacement
  overlapping an extremity of the set acts as if the old text were deleted
  first, then the new text added. This causes curtailment at either end.
  Replacement of the full text of the range removes the range from the set.

  **include** -
  New text added at the front or end of a range in a set extends the range, as
  does new text added within the range.  Replacement overlapping an extremity
  of the set acts as if the new text were added first, then the old text
  deleted.  This causes curtailment at the front of the range, extension at
  the end.  Replacement of the full text of the range adds the new text to the
  range if the start position of the replacement is at the range's start
  point.

  **exclude** -
  New text added at the front or end of a range in a set does not extend the
  range; new text added within the range extends the range.  Replacement
  overlapping an extremity causes curtailment of the range.  Replacement of
  the full text of the range removes the range from the set.

  **break** -
  New text added at the front or end of a range in a set does not extend the
  range; new text added within the range will split the range.  Replacement
  overlapping an extremity causes curtailment of the range.  Replacement of
  the full text of the range removes the range from the set.

4>Notes

  A rangeset is manipulated ~only~ through macro routines. Rangesets
  can easily become very large, and may exceed the capacity of the running
  process.  Coloring relies on proper color names or specifications (such as
  the "#rrggbb" hexadecimal digit strings), and appropriate hardware support. If
  an invalid color name is given, the default background color is used instead.
  Behaviours set using rangeset_set_mode() are subject to change in future
  versions.

3>Rangeset read-only variables

**$rangeset_list**
  array of active rangeset identifiers, with integer keys starting at 0,
  in the order the rangesets were defined.

3>Rangeset functions

**rangeset_create()**
**rangeset_create( n )**
  Creates one or more new rangesets. The first form creates a single range
  set and returns its identifier; if there are no rangesets available it
  returns 0. The second form creates n new rangesets, and returns an array
  of the rangeset identifiers with keys beginning at 0. If the requested
  number of rangesets is not available it returns an empty array.

**rangeset_destroy( r )**
**rangeset_destroy( array )**
  Deletes all information about a rangeset or a number of rangesets. The
  first form destroys the rangeset identified by r. The second form should
  be passed an array of rangeset identifiers with keys beginning at 0 (i.e.
  the same form of array returned by rangeset_create(n); it destroys all the
  rangesets appearing in the array. If any of the rangesets do not exist,
  the function continues without errors. Does not return a value.

**rangeset_add( r )**
**rangeset_add( r, start, end )**
**rangeset_add( r, r0 )**
  Adds to the rangeset r. The first form adds the range identified by the
  current primary selection to the rangeset, unless the selection is
  rectangular. The second form adds the range defined by the start and end
  positions given. The third form adds all ranges in the rangeset r0 to the
  rangeset r, and returns 0.

  Returns the index of the newly-added range within the rangeset.

**rangeset_subtract( r, [start, end] )**
**rangeset_subtract( r, r0 )**
  Removes from the rangeset r. The first form removes the range identified by
  the current primary selection from the rangeset, unless start and end are
  defined, in which case the range they define is removed. The second form
  removes all ranges in the rangeset r0 from the rangeset r. Does not return
  a value.

**rangeset_invert( r )**
  Changes the rangeset r so that it contains all ranges not in r. Does not
  return a value.

**rangeset_get_by_name( name )**
  Returns an array of active rangeset identifiers, with integer keys starting at 0,
  whose name matches name.

**rangeset_info( r )**
  Returns an array containing information about the rangeset r. The array
  has the following keys: **defined** (whether a rangeset with identifier
  r is defined), **count** (the number of ranges in the rangeset), **color**
  (the current background color of the rangeset, an empty string if the
  rangeset has no color), **name** (the user supplied name of the rangeset,
  an empty string if the rangeset has no name), and **mode** (the name of the
  modify-response mode of the rangeset).

**rangeset_range( r, [index] )**
  Returns details of a specific range in the rangeset r.  The range is
  specified by index, which should be between 1 and n (inclusive), where
  n is the number of ranges in the rangeset.  The return value is an array
  containing the keys **start** (the start position of the range) and **end**
  (the end position of the range).  If index is not supplied, the region
  returned is the span of the entire rangeset (the region starting at the
  start of the first range and ending at the end of the last).  If index
  is outside the correct range of values, the function returns an empty array.

**rangeset_includes( r, pos )**
  Returns the index of the range in rangeset r which includes pos; returns
  0 if pos is not contained in any of the ranges of r.  This can also be used
  as a simple true/false function which returns true if pos is contained in
  the rangeset.

**rangeset_set_color( r, color )**
  Attempts to apply the color as a background color to the ranges of r. If
  color is at empty string, removes the coloring of r.  No check is made
  regarding the validity of color: if the color is invalid (a bad name,
  or not supported by the hardware) this has unpredictable effects.

**rangeset_set_name( r, name )**
  Apply the name to the rangeset r.

**rangeset_set_mode( r, type )**
  Changes the behaviour of the rangeset r when modifications to the text
  buffer occur.  type can be one of the following: "maintain" (the default),
  "break", "include", "exclude", "ins_del" or "del_ins". (These modes are
  described above.)

Highlighting Information
------------------------

  The user can interrogate the current window to determine the color
  highlighting used on a particular piece of text. The following functions
  provide information on the highlighting pattern against which text at a
  particular position has been matched, its style, color and font attributes
  (whether the font is supposed to be bold and/or italic).

  These macro functions permit macro writers to generate formatted output which
  allows NEdit highlighting to be reproduced. This is suitable for the
  generation of HTML or Postscript output, for example.

  Note that if any of the functions is used while in Plain mode or while syntax
  highlighting is off, the behaviour is undefined.

**get_pattern_by_name( pattern_name )**
  Returns an array containing the pattern attributes for pattern 'pattern_name'.
  The elements in this array are:

* **style** -- Highlight style name

  If 'pattern_name' is invalid, an empty array is returned.

**get_pattern_at_pos( pos )**
  Returns an array containing the pattern attributes of the character at
  position 'pos'. The elements in this array are:

* **pattern** -- Highlight pattern name
* **style** -- Highlight style name
* **extent** -- The length in the text which uses the same highlighting pattern

  The 'extent' value is measured from position 'pos' going right/down (forward
  in the file) only.

  If 'pos' is invalid, an empty array is returned.

**get_style_by_name( style_name )**
  Returns an array containing the style attributes for style 'style_name'.
  The elements in this array are:

* **bold** -- '1' if style is bold, '0' otherwise
* **italic** -- '1' if style is italic, '0' otherwise
* **color** -- Name of the style's color
* **background** -- Name of the background color, if any

  The colors use the names specified in the color definitions for the style.
  These will either be names matching those the X server recognises, or RGB
  (red/green/blue) specifications.

  If 'style_name' is invalid, an empty array is returned.

**get_style_at_pos( pos )**
  Returns an array containing the style attributes of the character at
  position 'pos'. The elements in this array are:

* **style** -- Name of the highlight style
* **bold** -- '1' if style is bold, '0' otherwise
* **italic** -- '1' if style is italic, '0' otherwise
* **color** -- Name of the style's color
* **rgb** -- Color's RGB values ('#rrggbb')
* **background** -- Name of the background color, if any
* **back_rgb** -- Background color's RGB values ('#rrggbb')
* **extent** -- The length in the text which uses the same highlight style

  The colors use the names specified in the color definitions for the style.
  These will either be names matching those the X server recognises, or RGB
  specifications. The values for 'rgb' and 'back_rgb' contain the actual color
  values allocated by the X server for the window. If the X server cannot
  allocate the specified (named) color exactly, the RGB values in these
  entries may not match the specified ones.

  The 'extent' value is measured from position 'pos' going right/down (forward
  in the file) only.

  If 'pos' is invalid, an empty array is returned.

   ----------------------------------------------------------------------

Action Routines
---------------

  All of the editing capabilities of NEdit are represented as a special type of
  subroutine, called an action routine, which can be invoked from both macros
  and translation table entries (see "Key_Binding_" in the
  Customizing section of the Help menu).

  An action representing a menu command is usually named the same as its
  corresponding menu item except that all punctuation is removed, all letters
  are changed to lower case, and spaces are replaced with underscores.  To
  present a dialog to ask the user for input, use the actions with the
  `_dialog` suffix. Actions without the `_dialog` suffix take the information
  from the routine's arguments (see below).

    ~Arguments to new()~
                   "tab":      Open a new tab
                   "window":   Open a new window
                   "prefs":    Follow the user's tab/window
                               preference
                   "opposite": Opposite of user's tab/window
                               preference

  Set wrap text mode for the current window.

3>Keyboard-Only Actions

  In addition to the arguments listed in the call descriptions below, any
  routine involving cursor movement can take the argument "extend", meaning,
  adjust the primary selection to the new cursor position. Routines which take
  the "extend" argument as well as mouse dragging operations for both primary
  and secondary selections can take the optional keyword "rect", meaning, make
  the selection rectangular. Any routine that accepts the "scrollbar" argument
  will move the display but not the cursor or selection. Routines that accept
  the "nobell" argument will fail silently without beeping, when that argument
  is supplied.

**backward_character( ["nobell"] )**
  Moves the cursor one character to the left.

**backward_paragraph(["nobell"] )**
  Moves the cursor to the beginning of the paragraph, or
  if the cursor is already at the beginning of a paragraph, moves the cursor to
  the beginning of the previous paragraph.  Paragraphs are defined as regions
  of text delimited by one or more blank lines.

**backward_word( ["nobell"] )**
  Moves the cursor to the beginning of a word, or, if the
  cursor is already at the beginning of a word, moves the cursor to the
  beginning of the previous word.  Word delimiters are user-settable, and
  defined by the X resource wordDelimiters.

**beginning_of_file( ["scrollbar"] )**
  Moves the cursor to the beginning of the file.

**beginning_of_line( ["absolute"] )**
  Moves the cursor to the beginning of the line. If
  "absolute" is given, always moves to the absolute beginning of line,
  regardless of the text wrapping mode.

**beginning_of_selection()**
  Moves the cursor to the beginning of the selection
  without disturbing the selection.

**copy_clipboard()**
  Copies the current selection to the clipboard.

**copy_primary()**
  Copies the primary selection to the cursor.

**copy_to()**
  If a secondary selection exists, copies the secondary selection to
  the cursor.  If no secondary selection exists, copies the primary selection
  to the pointer location.

**copy_to_or_end_drag()**
  Completes either a secondary selection operation, or a
  primary drag.  If the user is dragging the mouse to adjust a secondary
  selection, the selection is copied and either inserted at the cursor
  location, or, if pending-delete is on and a primary selection exists in the
  window, replaces the primary selection.  If the user is dragging a block of
  text (primary selection), completes the drag operation and leaves the text at
  its current location.

**cut_clipboard()**
  Deletes the text in the primary selection and places it in
  the clipboard.

**cut_primary()**
  Copies the primary selection to the cursor and deletes it at
  its original location.

**delete_selection()**
  Deletes the contents of the primary selection.

**delete_next_character( ["nobell"] )**
  If a primary selection exists, deletes its contents.
  Otherwise, deletes the character following the cursor.

**delete_previous_character( ["nobell"] )**
  If a primary selection exists, deletes its
  contents.  Otherwise, deletes the character before the cursor.

**delete_next_word( ["nobell"] )**
  If a primary selection exists, deletes its contents.
  Otherwise, deletes the word following the cursor.

**delete_previous_word( ["nobell"] )**
  If a primary selection exists, deletes its contents.
  Otherwise, deletes the word before the cursor.

**delete_to_start_of_line( ["nobell", "wrap"] )**
  If a primary selection exists, deletes its contents.  Otherwise, deletes the
  characters between the cursor and the start of the line. If "wrap" is
  given, deletes to the previous wrap point or beginning of line, whichever
  is closest.

**delete_to_end_of_line( ["nobell", "absolute"] )**
  If a primary selection exists, deletes its contents.
  Otherwise, deletes the characters between the cursor and the end of the line.
  If "absolute" is given, always deletes to the absolute end of line, regardless
  of the text wrapping mode.

**deselect_all()**
  De-selects the primary selection.

**end_of_file( ["scrollbar"] )**
  Moves the cursor to the end of the file.

**end_of_line( ["absolute"] )**
  Moves the cursor to the end of the line.  If
  "absolute" is given, always moves to the absolute end of line, regardless
  of the text wrapping mode.

**end_of_selection()**
  Moves the cursor to the end of the selection without
  disturbing the selection.

**exchange( ["nobell"] )**
  Exchange the primary and secondary selections.

**extend_adjust()**
  Attached mouse-movement events to begin a selection between
  the cursor and the mouse, or extend the primary selection to the mouse
  position.

**extend_end()**
  Completes a primary drag-selection operation.

**extend_start()**
  Begins a selection between the cursor and the mouse.  A
  drag-selection operation can be started with either extend_start or
  grab_focus.

**focus_pane( [relative-pane] | [positive-index] | [negative-index] )**
  Move the focus to the requested pane.
  Arguments can be specified in the form of a relative-pane
  ("first", "last", "next", "previous"), a positive-index
  (numbers greater than 0, 1 is the same as "first") or a
  negative-index (numbers less than 0, -1 is the same as "last").

**forward_character()**
  Moves the cursor one character to the right.

**forward_paragraph( ["nobell"] )**
  Moves the cursor to the beginning of the next paragraph.
  Paragraphs are defined as regions of text delimited by one or more blank
  lines.

**forward_word( ["tail"] ["nobell"] )**
  Moves the cursor to the beginning of the next word.  Word
  delimiters are user-settable, and defined by the X resource wordDelimiters.
  If the "tail" argument is supplied the cursor will be moved to
  the end of the current word or the end of the next word, if the
  cursor is between words.

**grab_focus()**
  Moves the cursor to the mouse pointer location, and prepares for
  a possible drag-selection operation (bound to extend_adjust), or multi-click
  operation (a further grab_focus action).  If a second invocation of grab
  focus follows immediately, it selects a whole word, or a third, a whole line.

**insert_string( "string" )**
  If pending delete is on and the cursor is inside the
  selection, replaces the selection with "string".  Otherwise, inserts "string"
  at the cursor location.

**key_select( "direction" [,"nobell"] )**
  Moves the cursor one character in "direction"
  ("left", "right", "up", or "down") and extends the selection.  Same as
  forward/backward-character("extend"), or process-up/down("extend"), for
  compatibility with previous versions.

**move-destination()**
  Moves the cursor to the pointer location without
  disturbing the selection.  (This is an unusual way of working.  We left it in
  for compatibility with previous versions, but if you actually use this
  capability, please send us some mail, otherwise it is likely to disappear in
  the future.

**move_to()**
  If a secondary selection exists, deletes the contents of the
  secondary selection and inserts it at the cursor, or if pending-delete is on
  and there is a primary selection, replaces the primary selection.  If no
  secondary selection exists, moves the primary selection to the pointer
  location, deleting it from its original position.

**move_to_or_end_drag()**
  Completes either a secondary selection operation, or a
  primary drag.  If the user is dragging the mouse to adjust a secondary
  selection, the selection is deleted and either inserted at the cursor
  location, or, if pending-delete is on and a primary selection exists in the
  window, replaces the primary selection.  If the user is dragging a block of
  text (primary selection), completes the drag operation and deletes the text
  from its current location.

**newline()**
  Inserts a newline character.  If Auto Indent is on, lines up the
  indentation of the cursor with the current line.

**newline_and_indent()**
  Inserts a newline character and lines up the indentation
  of the cursor with the current line, regardless of the setting of Auto
  Indent.

**newline_no_indent()**
  Inserts a newline character, without automatic
  indentation, regardless of the setting of Auto Indent.

**next_page( ["stutter"] ["column"] ["scrollbar"] ["nobell"] )**
  Moves the cursor and scroll forward one page.
  The parameter "stutter" moves the cursor to the bottom of the display,
  unless it is already there, otherwise it will page down.
  The parameter "column" will maintain the preferred column while
  moving the cursor.

**page_left( ["scrollbar"] ["nobell"] )**
  Move the cursor and scroll left one page.

**page_right( ["scrollbar"] ["nobell"] )**
  Move the cursor and scroll right one page.

**paste_clipboard()**
  Insert the contents of the clipboard at the cursor, or if
  pending delete is on, replace the primary selection with the contents of the
  clipboard.

**previous_page( ["stutter"] ["column"] ["scrollbar"] ["nobell"] )**
  Moves the cursor and scroll backward one page.
  The parameter "stutter" moves the cursor to the top of the display,
  unless it is already there, otherwise it will page up.
  The parameter "column" will maintain the preferred column while
  moving the cursor.

**process_bdrag()**
  Same as secondary_or_drag_start for compatibility with previous versions.

**process_cancel()**
  Cancels the current extend_adjust, secondary_adjust, or
  secondary_or_drag_adjust in progress.

**process_down( ["nobell", "absolute"] )**
  Moves the cursor down one line.  If "absolute" is given, always moves to the
  next line in the text buffer, regardless of wrapping.

**process_return()**
  Same as newline for compatibility with previous versions.

**process_shift_down( ["nobell", "absolute"] )**
  Same as process_down("extend") for compatibility with previous versions.

**process_shift_up( ["nobell", "absolute"] )**
  Same as process_up("extend") for compatibility with previous versions.

**process_tab()**
  If tab emulation is turned on, inserts an emulated tab,
  otherwise inserts a tab character.

**process_up( ["nobell", "absolute"] )**
  Moves the cursor up one line.  If "absolute" is given, always moves to the
  previous line in the text buffer, regardless of wrapping.

**raise_window([relative-window] | [positive-index] | [negative-index] [, "focus" | "nofocus"])**
  Raise the current focused window to the front if no argument is supplied.
  Arguments can be specified in the form of a relative-window
  ("first", "last", "next", "previous"), a positive-index
  (numbers greater than 0, 1 is the same as "last") or a
  negative-index (numbers less than 0, -1 is the same as "first").

  Moreover, it can be specified whether or not the raised window should
  request the X input focus. By default, it depends on the setting of the
  nedit.focusOnRaise resource (see the section "X_Resources_") whether or not
  the input focus is requested.

**scroll_down( nUnits, ["lines" | "pages"] )**
  Scroll the display down (towards the end of the file) by a given
  number of units, units being lines or pages. Default units are lines.

**scroll_left( nPixels )**
  Scroll the display left by nPixels.

**scroll_right( nPixels )**
  Scroll the display right by nPixels.

**scroll_up( nUnits, ["lines" | "pages"] )**
  Scroll the display up (towards the beginning of the file) by a given
  number of units, units being lines or pages. Default units are lines.

**scroll_to_line( lineNum )**
  Scroll to position line number lineNum at the top of
  the pane.  The first line of a file is line 1.

**secondary_adjust()**
  Attached mouse-movement events to extend the secondary
  selection to the mouse position.

**secondary_or_drag_adjust()**
  Attached mouse-movement events to extend the
  secondary selection, or reposition the primary text being dragged.  Takes two
  optional arguments, "copy", and "overlay".  "copy" leaves a copy of the
  dragged text at the site at which the drag began.  "overlay" does the drag in
  overlay mode, meaning the dragged text is laid on top of the existing text,
  obscuring and ultimately deleting it when the drag is complete.

**secondary_or_drag_start()**
  To be attached to a mouse down event.  Begins drag
  selecting a secondary selection, or dragging the contents of the primary
  selection, depending on whether the mouse is pressed inside of an existing
  primary selection.

**secondary_start()**
  To be attached to a mouse down event.  Begin drag selecting
  a secondary selection.

**select_all()**
  Select the entire file.

**self_insert()**
  To be attached to a key-press event, inserts the character
  equivalent of the key pressed.

Customizing
===========

Customizing NEdit
-----------------

  NEdit can be customized in many different ways.  The most important
  user-settable options are presented in the Preferences menu, including all
  options that users might need to change during an editing session.  Options
  set in the Default Settings sub-menu of the Preferences menu can be preserved
  between sessions by selecting Save Defaults, which writes the changes to the
  preferences file.  See the section titled "Preferences_" for more details.

  User defined commands can be added to NEdit's Shell, Macro, and window
  background menus.  Dialogs for creating items in these menus can be found
  under Customize Menus in the Default Settings sub menu of the Preferences
  menu.

  For users who depend on NEdit every day and want to tune every excruciating
  detail, there are also X resources for tuning a vast number of such details,
  down to the color of each individual button.  See the section "X_Resources_"
  for more information, as well as a list of selected resources.

  The most common reason for customizing your X resources for NEdit, however, is
  key binding.  While limited key binding can be done through Preferences
  settings (Preferences -> Default Settings -> Customize Menus), you can really
  only add keys this way, and each key must have a corresponding menu item.
  Any significant changes to key binding should be made via the Translations
  resource and menu accelerator resources.  The sections titled "Key_Binding_"
  and "X_Resources_" have more information.
   ----------------------------------------------------------------------

Preferences
-----------

  The Preferences menu allows you to set options for both the current editing
  window, and default values for newly created windows and future NEdit
  sessions.  Options in the Preferences menu itself (not in the Default
  Settings sub-menu) take effect immediately and refer to the current window
  only.  Options in the Default Settings sub-menu provide initial settings for
  future windows created using the New or Open commands; options affecting all
  windows are also set here.

  Preferences set in the Default Settings sub-menu are saved in a file that
  NEdit reads at startup time, cf. Autoload_Files_, by selecting Save Defaults.

3>Preferences Menu

**Default Settings**
  Menu of initial settings for future windows.  Generally the same as the
  options in the main part of the menu, but apply as defaults for future
  windows created during this NEdit session.  These settings can be saved using
  the Save Defaults command below, to be loaded automatically each time NEdit
  is started.

**Save Defaults**
  Save the default options as set under Default Settings for future NEdit
  sessions.

**Statistics Line**
  Show the full file name, line number, and length of the file being edited.

**Incremental Search Line**
  Keep the incremental search bar (Search -> Find Incremental) permanently
  displayed at the top of the window.

**Show Line Numbers**
  Display line numbers to the right of the text.

**Language Mode**
  Tells NEdit what language (if any) to assume, for selecting language-specific
  features such as highlight patterns and smart indent macros, and setting
  language specific preferences like word delimiters, tab emulation, and
  auto-indent.  See Programming_with_NEdit_ for more information.

**Auto Indent**
  Setting Auto Indent "on" maintains a running indent (pressing the Return key
  will line up the cursor with the indent level of the previous line).  If
  smart indent macros are available for the current language mode, smart indent
  can be selected and NEdit will attempt to guess proper language indentation
  for each new line, cf. Auto/Smart_Indent_.

**Wrap**
  Choose between two styles of automatic wrapping or none.  Auto Newline wrap,
  wraps text at word boundaries when the cursor reaches the right margin, by
  replacing the space or tab at the last word boundary with a newline
  character.  Continuous Wrap wraps long lines which extend past the right
  margin. Continuous Wrap mode is typically used to produce files where
  newlines are omitted within paragraphs, to make text filling automatic (a
  kind of poor-man's word processor).  Text of this style is common on Macs and
  PCs but is not necessarily supported very well under Unix (except in programs
  which deal with e-mail, for which it is often the format of choice).

**Wrap Margin**
  Set margin for Auto Newline Wrap, Continuous Wrap, and Fill Paragraph.  Lines
  may, be wrapped at the right margin of the window, or the margin can be set
  at a specific column.

**Tab Stops**
  Set the tab distance (number of characters between tab stops) for tab
  characters, and control tab emulation and use of tab characters in padding
  and emulated tabs.

**Text Font...**
  Change the font(s) used to display text (fonts for menus and dialogs must be
  set using X resources for the text area of the window). See below for more
  information.

**Highlight Syntax**
  If NEdit recognizes the language being edited, and highlighting patterns are
  available for that language, use fonts and colors to enhance viewing of the
  file.  (See Syntax_Highlighting_ for more information.)

**Make Backup Copy**
  On Save, write a backup copy of the file as it existed before the Save
  command with the extension .bck (Unix only).

**Incremental Backup**
  Periodically make a backup copy of the file being edited under the name
  `~filename` on Unix or `_filename` on VMS (see Crash_Recovery_).

**Show Matching (..)**
  Momentarily highlight matching parenthesis, brackets, and braces, or the
  range between them, when one of these characters is typed, or when the
  insertion cursor is positioned after it. Delimiter only highlights the
  matching delimiter, while Range highlights the whole range of text between
  the matching delimiters.

  Optionally, the matching can make use of syntax information if syntax
  highlighting is enabled. Alternatively, the matching is purely character
  based. In general, syntax based matching results in fewer false matches.

**Overtype**
  In overtype mode, new characters entered replace the characters in front of
  the insertion cursor, rather than being inserted before them.

**Read Only**
  Lock the file against accidental modification.  This temporarily prevents the
  file from being modified in this NEdit session. Note that this is different
  from setting the file protection.

3>Preferences -> Default Settings Menu

  Options in the Preferences -> Default Settings menu have the same meaning as
  those in the top-level Preferences menu, except that they apply to future
  NEdit windows and future NEdit sessions if saved with the Save Defaults
  command.  Additional options which appear in this menu are:

**Language Modes**
  Define language recognition information (for determining language mode from
  file name or content) and set language specific preferences.

**Tag Collisions**
  How to react to multiple tags for the same name.  Tags are described in the
  section: Finding_Declarations_(ctags)_.  In Show All mode, all matching tags
  are displayed in a dialog.  In Smart mode, if one of the matching tags is in
  the current window, that tag is chosen, without displaying the dialog.

**Command Shell...**
  Set the shell used to run programs from the shell_command() macro function
  and from the Shell menu. This defaults to the user's login shell.

**Colors...**
  Change the colors used to display text.  The "Matching (..)" fields change the
  colors that matching parens, brackets and braces are flashed when the "Show
  Matching (..)" option is enabled.  Note that the foreground colors for plain
  text, selected text, and matching paren flashing only apply when syntax
  highlighting is disabled.  When syntax highlighting is enabled, text (even
  text that appears plain) will always be colored according to its highlighting
  style. (For information on changing syntax highlighting styles and matching
  patterns use see Syntax_Highlighting_.)

**Customize Menus**
  Add/remove items from the Shell, Macro, and window background menus (see
  below).

**Customize Window Title**
  Opens a dialog where the information to be displayed in the window's title
  field can be defined and tested. The dialog contains a Help button, providing
  further information about the options available.

**Searching**
  Options for controlling the behavior of Find and Replace commands:

  ~Verbose~ -
  Presents search results in dialog form, asks before wrapping a
  search back around the beginning (or end) of the file
  (unless Beep On Search Wrap is turned on).

  ~Wrap Around~ -
  Search and Replace operations wrap around the beginning (or end) of the file.

  ~Beep On Search Wrap~ -
  Beep when Search and Replace operations wrap around the beginning (or end) of
  the file (only if Wrap Around is turned on).

  ~Keep Dialogs Up~ -
  Don't pop down Replace and Find boxes after searching.

  ~Default Search Style~ -
  Initial setting for search type in Find and Replace dialogs.

  ~Default Replace Scope~ -
  [THIS OPTION IS ONLY PRESENT WHEN NEDIT WAS COMPILED WITH THE
   -DREPLACE_SCOPE FLAG TO SELECT AN ALTERNATIVE REPLACE DIALOG LAYOUT.]

  Initial setting for the scope in the Replace/Find dialog, when a selection
  exists. It can be either "In Window", "In Selection", or "Smart". "Smart"
  results in "In Window" if the size of the selection is smaller than 1 line,
  and to "In Selection" otherwise.

**Syntax Highlighting**
  Program and configure enhanced text display for new or supported languages.
  (See Syntax_Highlighting_.)

**Tabbed Editing**
  Options for controlling the tabbed interface:

  ~Open File in New Tab~ -
  Open files in new tabs, else open files in new windows.

  ~Show Tab Bar~ -
  Show/Hide the tab bar.

  ~Hide Tab Bar when only one Document is open~

  ~Next/Prev Tabs Across Windows~ -
  Suppose there are two windows with three tabs in the first window and two tabs in
  the second window.  Enabling this option, if you are on the third tab in the
  first window, hitting Ctrl+PageDown would switch to the first tab in the second
  window (instead of switching to the first tab in the first window).

  ~Sort Tabs Alphabetically~

**Show Tooltips**
  Show file name and path in a tooltip when moving the mouse pointer over a tab.
  (See Tabbed_Editing_.)

**Terminate with Line Break on Save**
  Some UNIX tools expect that files end with a line feed. If this option is
  activated, NEdit will append one if required.

**Sort Open Prev. Menu**
  Option to order the File -> Open Previous menu alphabetically, versus in
  order of last access.

**Popups Under Pointer**
  Display pop-up dialogs centered on the current mouse position, as opposed to
  centered on the parent window.  This generally speeds interaction, and is
  essential for users who set their window managers so keyboard focus
  follows the mouse.

**Auto-Scroll Near Window Top/Bottom**
  When this option is enabled the window will automatically scroll when the
  cursor comes 4 lines from the top or bottom of the window (except at the
  beginning of the file).  The number of lines can be customized with the
  nedit.autoScrollVPadding resource.

**Warnings**
  Options for controlling the popping up of warning dialogs:

  ~File Modified Externally~ -
  Pop up a warning dialog when files get changed external to NEdit.

  ~Check Modified File Contents~ -
  If external file modification warnings are requested, also check the file
  contents iso. only the modification date.

  ~On Exit~ -
  Ask before exiting when two or more files are open in an NEdit session
  or before closing a window with two or more tabs.

**Initial Window Size**
  Default size for new windows.

3>Changing Font(s)

  The font used to display text in NEdit is set under Preferences -> Text Font
  (for the current window), or Preferences -> Default Settings Text Font (for
  future windows).  These dialogs also allow you to set fonts for syntax
  highlighting.  If you don't intend to use syntax highlighting, you can ignore
  most of the dialog, and just set the field labeled Primary Font.

  Unless you are absolutely certain about the types of files that you will be
  editing with NEdit, you should choose a fixed-spacing font.  Many, if not
  most, plain-text files are written expecting to be viewed with fixed
  character spacing, and will look wrong with proportional spacing.  NEdit's
  filling, wrapping, and rectangular operations will also work strangely if you
  choose a proportional font.

  Note that in the font browser (the dialog brought up by the Browse...
  button), the subset of fonts which are shown is narrowed depending on the
  characteristics already selected.  It is therefore important to know that you
  can unselect characteristics from the lists by clicking on the selected items
  a second time.

  Fonts for syntax highlighting should ideally match the primary font in both
  height and spacing.  A mismatch in spacing will result in similar distortions
  as choosing a proportional font: column alignment will sometimes look wrong,
  and rectangular operations, wrapping, and filling will behave strangely.  A
  mismatch in height will cause windows to re-size themselves slightly when
  syntax highlighting is turned on or off, and increase the inter-line spacing
  of the text.  Unfortunately, on some systems it is hard to find sets of fonts
  which match exactly in height.

3>Customizing Menus

  You can add or change items in the Shell, Macro, and window background menus
  under Preferences -> Default Settings -> Customize Menus.  When you choose
  one of these, you will see a dialog with a list of the current
  user-configurable items from the menu on the left.  To change an existing
  item, select it from the list, and its properties will appear in the
  remaining fields of the dialog, where you may change them.  Selecting the
  item "New" from the list allows you to enter new items in the menu.

  Hopefully most of the characteristics are self explanatory, but here are a
  few things to note:

  Accelerator keys are keyboard shortcuts which appear on the right hand side
  of the menus, and allow you avoid pulling down the menu and activate the
  command with a single keystroke.  Enter accelerators by typing the keys
  exactly as you would to activate the command.

  Mnemonics are a single letter which should be part of the menu item name,
  which allow users to traverse and activate menu items by typing keys when the
  menu is pulled down.

  In the Shell Command field of the Shell Commands dialog, the % character
  expands to the name (including directory path) of the file in the window.  To
  include a % character in the command, use %%.

  The Menu Entry field can contain special characters for constructing
  hierarchical sub-menus, and for making items which appear only in certain
  language modes.  The right angle bracket character ">" creates a sub-menu.
  The name of the item itself should be the last element of the path formed
  from successive sub-menu names joined with ">".  Menu panes are called in to
  existence simply by naming them as part of a Menu Entry name.  To put several
  items in the same sub-menu, repeat the same hierarchical sequence for each.
  For example, in the Macro Commands dialog, two items with menu entries: a>b>c
  and a>b>d would create a single sub menu under the macro menu called "a",
  which would contain a single sub-menu, b, holding the actual items, c and d:

      +---++---++---+
      |a >||b >||c  |
      +---++---+|d  |
                +---+

  To qualify a menu entry with a language mode, simply add an at-sign "@@" at
  the end of the menu command, followed (no space) by a language mode name.  To
  make a menu item which appears in several language modes, append additional
  @@s and language mode names.  For example, an item with the menu entry:

    Make C Prototypes@@C@@C++

  would appear only in C and C++ language modes, and:

    Make Class Template@@C++

  would appear only in C++ mode.

  Menu items with no qualification appear in all language modes.

  If a menu item is followed by the single language qualification "@@*", that
  item will appear only if there are no applicable language-specific items of
  the same name in the same submenu.  For example, if you have the following
  three entries in the same menu:

    Make Prototypes@@C@@C++
    Make Prototypes@@Java
    Make Prototypes@@*

  The first will be available when the language mode is C or C++, the second
  when the language mode is Java, and for all other language modes (including
  the "Plain" non-language mode).  If the entry:

    Make Prototypes

  also exists, this will always appear, meaning that the menu will always have
  two "Make Prototypes" entries, whatever the language mode.

3>The NEdit Autoload Files

  At startup time, NEdit _automatically reads the preferences file
  `nedit.rc', the autoload macro file `autoload.nm', and the history data base
  `nedit.history'.  The preferences file contains saved preferences (menu
  settings) in the format of an X resource file.  The autoload macro file is a
  macro file containing macro commands and definitions that NEdit will
  execute at startup.  (NEdit doesn't create this file automatically.)
  Moreover, NEdit saves a list of the recently opened files, which appear under
  the Open Previous menu, in the history data base.

  By default the location of these files is '$HOME/.nedit/'.  A different
  directory can be given by letting the environment variable NEDIT_HOME
  point to it.

  Notice that NEdit still supports the older names for these files, which are
  `$HOME/.nedit', `$HOME/.neditmacro', and `$HOME/.neditdb', respectively. This
  old naming scheme will be used if NEdit detects that `$HOME/.nedit' is a
  regular file and NEDIT_HOME isn't set.

  (For VMS, the location of these files is '$NEDIT_HOME/' if NEDIT_HOME is set,
  and 'SYS$LOGIN:' otherwise.)

  The contents of the preferences file can be moved into another X resource
  file (see X_Resources_).  One reason for doing so would be to attach server
  specific preferences, such as a default font, to a particular X server.
  Another reason for moving preferences into an X resource file would be to
  keep preferences menu options and X resource settable options together in
  one place.  Though the files are the same format, additional resources
  should not be added to the preferences file, since NEdit modifies that file
  by overwriting it completely.  Note also that the contents of the
  preferences file takes precedence over the values in an X resource file.
  Using Save Defaults after moving the contents of your preferences file to
  your .Xdefaults file will re-create the preferences file, interfering with
  the options that you have moved.



3>Sharing Customizations with Other NEdit Users

  If you have written macro or shell menu commands, highlight patterns, or
  smart-indent macros that you want to share with other NEdit users, you can
  make a file which they can load into their NEdit environment.

  To load such a file, start NEdit with the command:

     nedit -import 

  In the new NEdit session, verify that the imported patterns or macros do what
  you want, then select Preferences -> Save Defaults.  Saving incorporates the
  changes into the NEdit preferences file, so the next time you run NEdit, you
  will not have to import the distribution file.

  Loading a customization file is automated, but creating one is not.  To
  produce a file to be imported by other users, you must make a copy of your own
  preferences file, and edit it, by hand, to remove everything but the
  few items of interest to the recipient.  Leave only the individual
  resource(s), and within those resources, only the particular macro, pattern,
  style, etc, that you wish to exchange.

  For example, to share a highlighting pattern set, you would include the
  patterns, any new styles you added, and language mode information only if the
  patterns are intended to support a new language rather than updating an
  existing one. For example:

     nedit.highlightPatterns:\
          My Language:1:0{\n\
                  Comment:"#":"$"::Comment::\n\
                  Loop Header:"^[ \\t]*loop:":::Loop::\n\
          }
     nedit.languageModes: My Language:.my::::::
     nedit.styles: Loop:blue:Bold

  Resources are in the format of X resource files, but the format of text
  within multiple-item resources like highlight patterns, language modes,
  macros, styles, etc., are private to NEdit.  Each resource is a string which
  ends at the first newline character not escaped with \, so you must be
  careful about how you treat ends of lines.  While you can generally just cut
  and paste indented sections, if something which was originally in the middle
  of a resource string is now at the end, you must remove the \ line
  continuation character(s) so it will not join the next line into the
  resource.  Conversely, if something which was originally at the end of a
  resource is now in the middle, you'll have to add continuation character(s)
  to make sure that the resource string is properly continued from beginning to
  end, and possibly newline character(s) (\n) to make sure that it is properly
  separated from the next item.
   ----------------------------------------------------------------------

X Resources
-----------

  NEdit has additional options to those provided in the Preferences menu which
  are set using X resources.  Like most other X programs, NEdit can be
  customized to vastly unnecessary proportions, from initial window positions
  down to the font and shadow colors of each individual button (A complete
  discussion of how to do this is left to books on the X Window System).  Key
  binding (see "Key_Binding_" is one of the most useful of these resource
  settable options.

  X resources are usually specified in a file called .Xdefaults or .Xresources
  in your home directory (on VMS this is sys$login:decw$xdefaults.dat).  On
  some systems, this file is read and its information attached to the X server
  (your screen) when you start X.  On other systems, the .Xdefaults file is
  read each time you run an X program.  When X resource values are attached to
  the X server, changes to the resource file are not available to application
  programs until you either run the xrdb program with the appropriate file as
  input, or re-start the X server.

3>Selected X Resource Names

  The following are selected NEdit resource names and default values for NEdit
  options not settable via the Preferences menu (for preference resource names,
  see your NEdit preference file):

**nedit.tagFile**: (not defined)

  This can be the name of a file, or multiple files separated by a colon (:)
  character, of the type produced by Exuberant Ctags or the Unix ctags
  command, which NEdit will load at startup time (see ctags_support_). The tag
  file provides a database from which NEdit can automatically open files
  containing the definition of a particular subroutine or data type.

**nedit.alwaysCheckRelativeTagsSpecs: True**

  When this resource is set to True, and there are tag files specified (with
  the nedit.tagFile resource, see above) as relative paths, NEdit will evaluate
  these tag value paths whenever a file is opened. All accessible tag files
  will be loaded at this time. When this resource value is False, relative path
  tag specifications will only be evaluated at NEdit startup time.

**nedit.wordDelimiters**: .,/\\`'!@@#%^&*()-=+{}[]":;<>?

  The set of characters which mark the boundaries between words. In addition
  to these, spaces, tabs, and newlines are always word boundaries.

  These boundaries take effect for the move-by-word (Ctrl+Arrow) and
  select-word (double click) commands, and for doing regex searches using the
  \B, < and > tokens.
  
  Note that this default value may be overridden by the setting in
  Preferences -> Default Settings -> Language Modes....

**nedit.remapDeleteKey**: False

  Setting this resource to True forcibly maps the delete key to backspace. This
  can be helpful on systems where the bindings have become tangled, and in
  environments which mix systems with PC style keyboards and systems with DEC
  and Macintosh keyboards.  Theoretically, these bindings should be made using
  the standard X/Motif mechanisms, outside of NEdit.  In practice, some
  environments where users access several different systems remotely, can be
  very hard to configure. If you've given up and are using a backspace key
  halfway off the keyboard because you can't figure out the bindings, set this
  to True.

**nedit.typingHidesPointer**: False

  Setting this resource to True causes the mouse pointer to be hidden when you
  type in the text area. As soon as the mouse pointer is moved, it will
  reappear.  This is useful to stop the mouse pointer from obscuring text.

**nedit.overrideDefaultVirtualKeyBindings**: Auto

  Motif uses a virtual key binding mechanism that shares the bindings between
  different Motif applications. When a first Motif application is started, it
  installs some default virtual key bindings and any other Motif application
  that runs afterwards, simply reuses them. Obviously, if the first
  application installs an invalid set, all others applications may have
  problems.

  In the past, NEdit has been the victim of invalid bindings installed by other
  applications several times. Through this resource, NEdit can be instructed
  to ignore the bindings installed by other applications, and use its own
  private bindings. By default, NEdit tries to detect invalid bindings
  and ignore them automatically (Auto). Optionally, NEdit can be told to
  always keep the installed bindings (Never), or to always override them
  (Always).

**nedit.stdOpenDialog**: False

  Setting this resource to True restores the standard Motif style of Open
  dialog.  NEdit file open dialogs are missing a text field at the bottom of
  the dialog, where the file name can be entered as a string.  The field is
  removed in NEdit to encourage users to type file names in the list, a
  non-standard, but much faster method for finding files.

**nedit.bgMenuButton**: @~Shift@~Ctrl@~Meta@~Alt

  Specification for mouse button / key combination to post the background menu
  (in the form of an X translation table event specification).  The event
  specification should be as specific as possible, since it will override less
  specific translation table entries.

**nedit.maxPrevOpenFiles**: 30

  Number of files listed in the Open Previous sub-menu of the File menu.
  Setting this to zero disables the Open Previous menu item and maintenance of
  the NEdit file history file.

**nedit.printCommand**: (system specific)

  Command used by the print dialog to print a file, such as, lp, lpr, etc..
  The command must be capable of accepting input via stdin (standard input).

**nedit.printCopiesOption**: (system specific)

  Option name used to specify multiple copies to the print command.  If the
  option should be separated from its argument by a space, leave a trailing
  space. If blank, no "Number of Copies" item will appear in the print dialog.

**nedit.printQueueOption**: (system specific)

  Option name used to specify a print queue to the print command.  If the
  option should be separated from its argument by a space, leave a trailing
  space. If blank, no "Queue" item will appear in the print dialog.

**nedit.printNameOption**: (system specific)

  Option name used to specify a job name to the print command.  If the option
  should be separated from its argument by a space, leave a trailing space. If
  blank, no job or file name will be attached to the print job or banner page.

**nedit.printHostOption**: (system specific)

  Option name used to specify a host name to the print command.  If the option
  should be separated from its argument by a space, leave a trailing space. If
  blank, no "Host" item will appear in the print dialog.

**nedit.printDefaultQueue**: (system specific)

  The name of the default print queue.  Used only to display in the print
  dialog, and has no effect on printing.

**nedit.printDefaultHost**: (system specific)

  The node name of the default print host.  Used only to display in the print
  dialog, and has no effect on printing.

**nedit.visualID**: Best

  If your screen supports multiple visuals (color mapping models), this
  resource allows you to manually choose among them.  The default value of
  "Best" chooses the deepest (most colors) visual available. Since NEdit does
  not depend on the specific characteristics of any given color model, Best
  probably IS the best choice for everyone, and the only reason for setting
  this resource would be to patch around some kind of X server problem. The
  resource may also be set to "Default", which chooses the screen's default
  visual (often a color-mapped, PseudoColor, visual for compatibility with
  older X applications).  It may also be set to a numeric visual-id value (use
  xdpyinfo to see the list of visuals supported by your display), or a visual
  class name: PseudoColor, DirectColor, TrueColor, etc..

  If you are running under a themed environment (like KDE or CDE) that places
  its colors in a shallow visual, and you'd rather have that color scheme
  instead of more colors available, then you may need set the visual to
  "Default" so that NEdit doesn't choose one with more colors.  (The reason
  for this is: if the "best" visual is not the server's default, then NEdit
  cannot use the colors provided by your environment.  NEdit will fall back to
  its own default color scheme.)

**nedit.installColormap**: False

  Force the installation of a private colormap.  If you have a humble 8-bit
  color display, and netscape is hogging all of the color cells, you may want
  to try turning this on.  On most systems, this will result in colors flashing
  wildly when you switch between NEdit and other applications.  But a few
  systems (SGI) have hardware support for multiple simultaneous colormaps, and
  applications with installed colormaps are well behaved.

**nedit.findReplaceUsesSelection**: False

  Controls if the Find and Replace dialogs are automatically loaded with the
  contents of the primary selection.

**nedit.stickyCaseSenseButton**: True

  Controls if the "Case Sensitive" buttons in the Find and Replace dialogs and
  the incremental search bar maintain a separate state for literal and regular
  expression searches. Moreover, when set to True, by default literal searches
  are case insensitive and regular expression searches are case sensitive. When
  set to False, the "Case Sensitive" buttons are independent of the "Regular
  Expression" toggle.

**nedit.multiClickTime**: (system specific)

  Maximum time in milliseconds allowed between mouse clicks within double and
  triple click actions.

**nedit.undoModifiesSelection**: True

  By default, NEdit selects any text inserted or changed through a undo/redo
  action.  Set this resource to False if you don't want your selection to be
  touched.

**nedit@*scrollBarPlacement**: BOTTOM_RIGHT

  How scroll bars are placed in NEdit windows, as well as various lists and
  text fields in the program. Other choices are: BOTTOM_LEFT, TOP_LEFT, or
  TOP_RIGHT.

**nedit@*text.autoWrapPastedText**: False

  When Auto Newline Wrap is turned on, apply automatic wrapping (which
  normally only applies to typed text) to pasted text as well.

**nedit@*text.heavyCursor**: False

  For monitors with poor resolution or users who have difficulty seeing the
  cursor, makes the cursor in the text editing area of the window heavier and
  darker.

**nedit.autoScrollVPadding**: 4

  Number of lines to keep the cursor away from the top or bottom line of the
  window when the "Auto-Scroll Near Window Top/Bottom" feature is enabled.
  Keyboard operations that would cause the cursor to get closer than
  this distance cause the window to scroll up or down instead, except at the
  beginning of the file.  Mouse operations are not affected.

**nedit@*text.blinkRate**: 500

  Blink rate of the text insertion cursor in milliseconds.  Set to zero to stop
  blinking.

**nedit@*text.Translations**:

  Modifies key bindings (see "Key_Binding_").

**nedit@*foreground**: black

  Default foreground color for menus, dialogs, scroll bars, etc..

**nedit@*background**: #b3b3b3

  Default background color for menus, dialogs, scroll bars, etc..

**nedit@*calltipForeground**: black

  Foreground color for calltips

**nedit@*calltipBackground**: LemonChiffon1

  Background color for calltips

**nedit@*XmLFolder.inactiveForeground**: #666

  Foreground color for inactive tabs.

**nedit@*fontList**: helvetica medium 12 points

  Default font for menus, dialogs, scroll bars, etc..

**nedit.helpFont**: helvetica medium 12 points

  Font used for displaying online help.

**nedit.boldHelpFont**: helvetica bold 12 points

  Bold font for online help.

**nedit.italicHelpFont**: helvetica italic 12 points

  Italic font for online help.

**nedit.fixedHelpFont**: courier medium 12 points

  Fixed font for online help.

**nedit.boldFixedHelpFont**: courier bold 12 points

  Fixed bold for online help.

**nedit.italicFixedHelpFont**: courier italic 12 points

  Fixed italic font for online help.

**nedit.h1HelpFont**: helvetica bold 14 points

  Font for level-1 titles in help text.

**nedit.h2HelpFont**: helvetica bold italic 12 points

  Font for level-2 titles in help text.

**nedit.h3HelpFont**: courier bold 12 points

  Font for level-3 titles in help text.

**nedit.helpLinkFont**: helvetica medium 12 points

  Font for hyperlinks in the help text

**nedit.helpLinkColor**: #009900

  Color for hyperlinks in the help text

**nedit.backlightCharTypes**:  0-8,10-31,127:red;9:#dedede;32,160-255:#f0f0f0;128-159:orange

  **NOTE: backlighting is ~experimental~** (see "Programming_with_NEdit_").

  A string specifying character classes as ranges of ASCII values followed by
  the color to be used as their background colors.  The format is:

  low[-high]{,low[-high]}:color{;low-high{,low[-high]}:color}

  where low and high are ASCII values.

  For example:
    32-255:#f0f0f0;1-31,127:red;128-159:orange;9-13:#e5e5e5
  
.. DISABLED for 5.4
..  The macro built-in function set_backlight_string() allows these strings to be
..  set for a particular window.

**nedit.focusOnRaise**: False

  This resource determines whether new text windows and text windows that are
  raised, should also request the input focus.  Conventionally, it is the task
  of the window manager to decide on which window gets the input focus.
  Therefore, NEdit's default behaviour is not to request the input focus
  explicitly.

**nedit.forceOSConversion**: True

  By default, NEdit converts texts in DOS or Mac format to an internal
  format using simple newlines as line dividers. This is sometimes not
  wanted by the user and can be prevented by setting this resource to
  False.
  
  Note: Setting this to False would supress newlines in Mac files entirely,
  leaving the control character  where every line feed would be. Mac OS
  X uses Unix files and is not affected.

  Note: Setting this to False while the option 'Terminate with Line Break
  on Save' is active could lead to file corruption.

**nedit.truncSubstitution**: Fail

  NEdit has a fixed limit on substitution result string length. This
  resource modifies the behaviour if this limit is exceeded. Possible
  values are ~Silent~ (will silently fail the operation), ~Fail~ (will fail
  the operation and pop up a dialog informing the user), ~Warn~ (pops up a
  dialog warning the user, offering to cancel the operation) and ~Ignore~
  (will silently conclude the operation).

  **WARNING**: Setting this to 'Ignore' will destroy data without warning!

**nedit.honorSymlinks**: True

  If set to True, NEdit will open a requested file on disk even if it is a
  symlink pointing to a file already opened in another window. If set to false,
  NEdit will try to detect these cases and just pop up the already opened
  document.

**nc.autoStart**: True 

  Whether the nc program should automatically start an NEdit server (without
  prompting the user) if an appropriate server is not found.

**nc.serverCommand**: nedit -server

  Command used by the nc program to start an NEdit server.

**nc.timeOut**: 10

  Basic time-out period used in communication with an NEdit server (seconds).

   ----------------------------------------------------------------------
  ~The following are Selected widget names (to which you may append~
  ~.background, .foreground, .fontList, etc., to change colors, fonts~
  ~ and other characteristics):~

**nedit@*statsAreaForm**

  Statistics line and incremental search bar.  To get consistent results across
  the entire stats line and the incremental search bar, use '*' rather than '.'
  to separate the resource name.  For example, to set the foreground color of
  both components use:
    nedit*statsAreaForm*foreground
  instead of:
    nedit*statsAreaForm.foreground

**nedit@*menuBar**

  Top-of-window menu-bar.

**nedit@*textHorScrollBar**

  Horizontal scroll bar.

**nedit@*textVertScrollBar**

  Vertical scroll bar.
   ----------------------------------------------------------------------

Key Binding
-----------

  There are several ways to change key bindings in NEdit.  The easiest way to
  add a new key binding in NEdit is to define a macro in Preferences -> Default
  Settings -> Customize Menus -> Macro Menu.  However, if you want to change
  existing bindings or add a significant number of new key bindings you will
  need to do so via X resources.

  Before reading this section, you must understand how to set X resources (see
  the help section "X_Resources_").  Since setting X resources is tricky, it is
  also helpful when working on key-binding, to set some easier-to-verify
  resource at the same time, as a simple check that the NEdit program is
  actually seeing your changes.  The appres program is also very helpful in
  checking that the resource settings that you make, actually reach the program
  for which they are intended in the correct form.

3>Key Binding in General

  Keyboard commands are associated with editor action routines through two
  separate mechanisms in NEdit.  Commands which appear in pull-down menus have
  individual resources designating a keyboard equivalent to the menu command,
  called an accelerator key.  Commands which do not have an associated menu
  item are bound to keys via the X toolkit translation mechanism.  The methods
  for changing these two kinds of bindings are quite different.

3>Key Binding Via Translations

  The most general way to bind actions to keys in NEdit is to use the
  translation table associated with the text widget.  To add a binding to Alt+Y
  to insert the string "Hi!", for example, add lines similar to the following
  to your X resource file:

    NEdit*text.Translations: #override \n\
      Alty: insert_string("Hi!") \n

  The Help topic "Action_Routines_" lists the actions available to be bound.

  Translation tables map key and mouse presses, window operations, and other
  kinds of events, to actions. The syntax for translation tables is
  simplified here, so you may need to refer to a book on the X window system
  for more detailed information.

  Note that accelerator resources (discussed below) override translations, and
  that most Ctrl+letter and Alt+letter combinations are already bound to an
  accelerator key.  To use one of these combinations from a translation table,
  therefore, you must first un-bind the original menu accelerator.

  A resource for changing a translation table consists of a keyword; #override,
  #augment, or #replace; followed by lines (separated by newline characters)
  pairing events with actions.  Events begin with modifiers, like Ctrl, Shift,
  or Alt, followed by the event type in <>.  BtnDown, Btn1Down, Btn2Down,
  Btn1Up, Key, KeyUp are valid event types.  For key presses, the event type is
  followed by the name of the key.  You can specify a combination of events,
  such as a sequence of key presses, by separating them with commas.  The other
  half of the event/action pair is a set of actions.  These are separated from
  the event specification by a colon and from each other by spaces.  Actions
  are names followed by parentheses, optionally containing one or more
  parameters separated by comas.

3>Changing Menu Accelerator Keys

  The menu shortcut keys shown at the right of NEdit menu items can also be
  changed via X resources.  Each menu item has two resources associated with
  it, accelerator, the event to trigger the menu item; and acceleratorText, the
  string shown in the menu.  The form of the accelerator resource is the same
  as events for translation table entries discussed above, though multiple keys
  and other subtleties are not allowed.  The resource name for a menu is the
  title in lower case, followed by "Menu", the resource name of menu item is
  the name in lower case, run together, with words separated by caps, and all
  punctuation removed.  For example, to change Cut to Ctrl+X, you would add the
  following to your .Xdefaults file:

      nedit*editMenu.cut.accelerator: Ctrlx
      nedit*editMenu.cut.acceleratorText: Ctrl+X

  Accelerator keys with optional shift key modifiers, like Find..., have an
  additional accelerator resource with Shift appended to the name.  For
  example:

      nedit*searchMenu.find.acceleratorText: [Shift]Alt+F
      nedit*searchMenu.find.accelerator: Altf
      nedit*searchMenu.findShift.accelerator: Shift Altf
   ----------------------------------------------------------------------

Highlighting Patterns
---------------------

3>Writing Syntax Highlighting Patterns

  Patterns are the mechanism by which language syntax highlighting is
  implemented in NEdit (see Syntax_Highlighting_ under the heading of Features
  for Programming). To create syntax highlighting patterns for a new
  language, or to modify existing patterns, select "Recognition Patterns" from
  "Syntax Highlighting" sub-section of the "Default Settings" sub-menu of the
  "Preferences" menu.

  First, a word of caution.  As with regular expression matching in general, it
  is quite possible to write patterns which are so inefficient that they
  essentially lock up the editor as they recursively re-examine the entire
  contents of the file thousands of times.  With the multiplicity of patterns,
  the possibility of a lock-up is significantly increased in syntax
  highlighting.  When working on highlighting patterns, be sure to save your
  work frequently.

  NEdit's syntax highlighting is unusual in that it works in real-time (as you
  type), and yet is completely programmable using standard regular expression
  notation.  Other syntax highlighting editors usually fall either into the
  category of fully programmable but unable to keep up in real-time, or
  real-time but limited programmability.  The additional burden that NEdit
  places on pattern writers in order to achieve this speed/flexibility mix, is
  to force them to state self-imposed limitations on the amount of context that
  patterns may examine when re-parsing after a change.  While the "Pattern
  Context Requirements" heading is near the end of this section, it is not
  optional, and must be understood before making any serious effort at
  pattern writing.

  In its simplest form, a highlight pattern consists of a regular expression to
  match, along with a style representing the font an color for displaying any
  text which matches that expression.  To bold the word, "highlight", wherever
  it appears the text, the regular expression simply would be the word
  "highlight".  The style (selected from the menu under the heading of
  "Highlight Style") determines how the text will be drawn.  To bold the text,
  either select an existing style, such as "Keyword", which bolds text, or
  create a new style and select it under Highlight Style.

  The full range of regular expression capabilities can be applied in such a
  pattern, with the single caveat that the expression must conclusively match
  or not match, within the pre-defined context distance (as discussed below
  under Pattern Context Requirements).

  To match longer ranges of text, particularly any constructs which exceed the
  requested context, you must use a pattern which highlights text between a
  starting and ending regular expression match.  To do so, select "Highlight
  text between starting and ending REs" under "Matching", and enter both a
  starting and ending regular expression.  For example, to highlight everything
  between double quotes, you would enter a double quote character in both the
  starting and ending regular expression fields.  Patterns with both a
  beginning and ending expression span all characters between the two
  expressions, including newlines.

  Again, the limitation for automatic parsing to operate properly is that both
  expressions must match within the context distance stated for the pattern
  set.

  With the ability to span large distances, comes the responsibility to recover
  when things go wrong.  Remember that syntax highlighting is called upon to
  parse incorrect or incomplete syntax as often as correct syntax.  To stop a
  pattern short of matching its end expression, you can specify an error
  expression, which stops the pattern from gobbling up more than it should.
  For example, if the text between double quotes shouldn't contain newlines,
  the error expression might be "$".  As with both starting and ending
  expressions, error expressions must also match within the requested context
  distance.

4>Coloring Sub-Expressions

  It is also possible to color areas of text within a regular expression
  match.  A pattern of this type associates a style with sub-expressions
  references of the parent pattern (as used in regular expression substitution
  patterns, see the NEdit Help menu item on Regular_Expressions_).
  Sub-expressions of both the starting and ending patterns may be colored.  For
  example, if the parent pattern has a starting expression "\<", and end
  expression "\>", (for highlighting all of the text contained within angle
  brackets), a sub-pattern using "&" in both the starting and ending expression
  fields could color the brackets differently from the intervening text.  A
  quick shortcut to typing in pattern names in the Parent Pattern field is to
  use the middle mouse button to drag them from the Patterns list.

  In some cases, there can be interference between coloring sub-patterns and
  hierarchical sub-patterns (discussed next). How this is resolved, is
  explained below.

4>Hierarchical Patterns

  A hierarchical sub-pattern, is identical to a top level pattern, but is
  invoked only between the starting and ending expression matches of its
  parent pattern or, in case the parent pattern consists of a single
  expression, inside the text area matching that expression.  Like the
  sub-expression coloring patterns discussed above, it is associated with a
  parent pattern using the Parent Pattern field in the pattern specification.
  Pattern names can be dragged from the pattern list with the middle mouse
  button to the Parent Pattern field.

  The matching behaviour for sub-patterns is slightly different, depending on
  whether the parent pattern consists of a single expression or has both a
  starting and an ending expression.

  In case the parent pattern consists of a single expression, and the syntax
  highlighting parser finds a match for that expression, sub-patterns are
  matched between the start and the end of the parent match.  Sub-patterns
  cannot extend beyond the boundaries of the parent's match nor can they
  affect those boundaries (the latter can happen for starting/ending parent
  patterns, see below). Note that sub-patterns can ~peek~ beyond the
  parent's matching boundaries by means of look-ahead or look-behind
  expressions.

  In case the parent pattern is a starting/ending style pattern, after the
  start expression of the parent pattern matches, the syntax highlighting
  parser searches for either the parent's end pattern or a matching
  sub-pattern.  When a sub-pattern matches, control is not returned to the
  parent pattern until the entire sub-pattern has been parsed, regardless of
  whether the parent's end pattern appears in the text matched by the
  sub-pattern.  In this way, matching of the parent's ending pattern can be
  postponed, in contrast to the case where the parent pattern consists of a
  single expression. Note that, in this case, parsing of sub-patterns starts
  **after** the match of the parent pattern's starting expression, also in
  contrast to the single-expression case.

  The most common use for this capability is for coloring sub-structure of
  language constructs (smaller patterns embedded in larger patterns).
  Hierarchical patterns can also simplify parsing by having sub-patterns "hide"
  special syntax from parent patterns, such as special escape sequences or
  internal comments.

  There is no depth limit in nesting hierarchical sub-patterns, but beyond the
  third level of nesting, automatic re-parsing will sometimes have to re-parse
  more than the requested context distance to guarantee a correct parse (which
  can slow down the maximum rate at which the user can type if large sections
  of text are matched only by deeply nested patterns).

  While this is obviously not a complete hierarchical language parser it is
  still useful in many text coloring situations.  As a pattern writer, your
  goal is not to completely cover the language syntax, but to generate
  colorings that are useful to the programmer.  Simpler patterns are usually
  more efficient and also more robust when applied to incorrect code.

  Note that in case of a single-expression parent pattern, there is a
  potential for conflicts between coloring-only sub-patterns and hierarchical
  sub-patterns (which cannot happen for starting/ending type of patterns,
  because sub-patterns are matched **between** the starting and ending pattern
  (not included)).  Due to the different nature of these two kinds of
  sub-patterns, it is technically infeasible to follow the standard matching
  precedence rules, where a sub-pattern has precedence over the sub-patterns
  following it.  Instead, coloring-only sub-patterns are always colored last,
  ie., they may override the coloring for overlapping sibling sub-patterns in
  the overlapping parts of the matches.

4>Deferred (Pass-2) Parsing

  NEdit does pattern matching for syntax highlighting in two passes.  The first
  pass is applied to the entire file when syntax highlighting is first turned
  on, and to new ranges of text when they are initially read or pasted in.  The
  second pass is applied only as needed when text is exposed (scrolled in to
  view).

  If you have a particularly complex set of patterns, and parsing is beginning
  to add a noticeable delay to opening files or operations which change large
  regions of text, you can defer some of that parsing from startup time, to
  when it is actually needed for viewing the text.  Deferred parsing can only
  be used with single expression patterns, or begin/end patterns which match
  entirely within the requested context distance.  To defer the parsing of a
  pattern to when the text is exposed, click on the Pass-2 pattern type button
  in the highlight patterns dialog.

  Sometimes a pattern can't be deferred, not because of context requirements,
  but because it must run concurrently with pass-1 (non-deferred) patterns.  If
  they didn't run concurrently, a pass-1 pattern might incorrectly match some
  of the characters which would normally be hidden inside of a sequence matched
  by the deferred pattern.  For example, C has character constants enclosed in
  single quotes.  These typically do not cross line boundaries, meaning they
  can be parsed entirely within the context distance of the C pattern set and
  should be good candidates for deferred parsing.  However, they can't be
  deferred because they can contain sequences of characters which can trigger
  pass-one patterns. Specifically, the sequence, '\"', contains a double quote
  character, which would be matched by the string pattern and interpreted as
  introducing a string.

4>Pattern Context Requirements

  The context requirements of a pattern set state how much additional text
  around any change must be examined to guarantee that the patterns will match
  what they are intended to match.  Context requirements are a promise by NEdit
  to the pattern writer, that the regular expressions in his/her patterns will
  be matched against at least  lines and 
  characters, around any modified text.  Combining line and character
  requirements guarantee that both will be met.

  Automatic re-parsing happens on EVERY KEYSTROKE, so the amount of context
  which must be examined is very critical to typing efficiency.  The more
  complicated your patterns, the more critical the context becomes.  To cover
  all of the keywords in a typical language, without affecting the maximum rate
  at which users can enter text, you may be limited to just a few lines and/or
  a few hundred characters of context.

  The default context distance is 1 line, with no minimum character
  requirement.  There are several benefits to sticking with this default.  One
  is simply that it is easy to understand and to comply with.  Regular
  expression notation is designed around single line matching.  To span lines
  in a regular expression, you must explicitly mention the newline character
  "\n", and matches which are restricted to a single line are virtually immune
  to lock-ups.  Also, if you can code your patterns to work within a single
  line of context, without an additional character-range context requirement,
  the parser can take advantage the fact that patterns don't cross line
  boundaries, and nearly double its efficiency over a one-line and 1-character
  context requirement.  (In a single line context, you are allowed to match
  newlines, but only as the first and/or last character.)
   ----------------------------------------------------------------------

Smart Indent Macros
-------------------

  Smart indent macros can be written for any language, but are usually more
  difficult to write than highlighting patterns.  A good place to start, of
  course, is to look at the existing macros for C and C++.

  Smart indent macros for a language mode consist of standard NEdit macro
  language code attached to any or all of the following three activation
  conditions: 1) When smart indent is first turned on for a text window
  containing code of the language, 2) When a newline is typed and smart indent
  is expected, 3) after any character is typed.  To attach macro code to any of
  these code "hooks", enter it in the appropriate section in the Preferences ->
  Default Settings -> Auto Indent -> Program Smart Indent dialog.

  Typically most of the code should go in the initialization section, because
  that is the appropriate place for subroutine definitions, and smart indent
  macros are complicated enough that you are not likely to want to write them
  as one monolithic run of code.  You may also put code in the Common/Shared
  Initialization section (accessible through the button in the upper left
  corner of the dialog).  Unfortunately, since the C/C++ macros also reside in
  the common/shared section, when you add code there, you run some risk of
  missing out on future upgrades to these macros, because your changes will
  override the built-in defaults.

  The newline macro is invoked after the user types a newline, but before the
  newline is entered in the buffer.  It takes a single argument ($1) which is
  the position at which the newline will be inserted.  It must return the
  number of characters of indentation the line should have, or -1.  A return
  value of -1 means to do a standard auto-indent.  You must supply a newline
  macro, but the code: "return -1" (auto-indent), or "return 0" (no indent) is
  sufficient.

  The type-in macro takes two arguments.  $1 is the insert position, and $2 is
  the character just typed, and does not return a value.  It also is invoked
  before the character is inserted into the buffer.  You can do just about
  anything here, but keep in mind that this macro is executed for every
  keystroke typed, so if you try to get too fancy, you may degrade performance.

**-read**
  Open the file Read Only regardless of the actual file protection.

**-create**
  Don't warn about file creation when a file doesn't exist.

**-line n (or +n)**
  Go to line number n

**-server**
  Designate this session as an NEdit server, for processing commands from the
  nc program.  nc can be used to interface NEdit to code development
  environments, mailers, etc., or just as a quick way to open files from the
  shell command line without starting a new NEdit session.

**-do command**
  Execute an NEdit macro or action on the file following the -do argument on
  the command line. -do is particularly useful from the nc program, where
  nc -do can remotely execute commands in an NEdit -server session.

**-tags file**
  Load a file of directions for finding definitions of program subroutines and
  data objects.  The file must be of the format generated by Exuberant Ctags,
  or the standard Unix ctags command.

**-tabs n**
  Set tab stops every n characters.

**-wrap, -nowrap**
  Wrap long lines at the right edge of the window rather than continuing them
  past it.  (Continuous Wrap mode)

**-autowrap, -noautowrap**
  Wrap long lines when the cursor reaches the right edge of the window by
  inserting newlines at word boundaries.  (Auto Newline Wrap mode)

**-autoindent, -noautoindent**
  Maintain a running indent.

**-autosave, -noautosave**
  Maintain a backup copy of the file being edited under the name '~filename'.

**-rows n**
  Default height in characters for an editing window.

**-columns n**
  Default width in characters for an editing window.

**-font font (or -fn font)**
  Font for text being edited (Font for menus and dialogs can be set with -xrm
  "*fontList:font").

**-lm languagemode**
  Initial language mode used for editing succeeding files.

**-geometry geometry (or -g geometry)**
  The initial size and/or location of editor windows.  The argument geometry
  has the form:

   [x][+|-][[+|-]]

  where  and  are the desired width and height of the window,
  and  and  are the distance from the edge of the screen to
  the window, + for top or left, - for bottom or right.  -geometry can be
  specified for individual files on the command line.

**-iconic, -noiconic**
  Initial window state for succeeding files.

**-display [host]:server[.screen]**
  The name of the X server to use.  host specifies the machine, server
  specifies the display server number, and screen specifies the screen number.
  host or screen can be omitted and default to the local machine, and screen 0.

**-background color (or -bg color)**
  User interface background color. (Background color for text can be set
  separately with -xrm "nedit.textBgColor: color" or using the Preferences ->
  Colors dialog).

**-foreground color (or -fg color)**
  User interface foreground color. (Foreground color for text can be set
  separately with -xrm "nedit.textFgColor: color" or using the Preferences
  -> Colors dialog).

**-tabbed**
  Open all subsequent files in new tabs. Resets -group option.

**-untabbed**
  Open all subsequent files in new windows. Resets -group option. Note
  that this only works on subsequent files in this command and does not put
  NEdit in tab-less mode; for that you can use the command
    nedit -xrm "nedit.openInTab: False" -xrm "nedit.tabBarHideOne: True"
  This will affect your default settings for the session, and will be saved
  if Preferences->Save Defaults... is used, which may not be desired.

**-group**
  Open all subsequent files as tabs in a new window.

**-xrm resourcestring**
  Set the value of an X resource to override a default
  value (see "Customizing_NEdit_").

**-svrname name**
  When starting NEdit in server mode, name the server, such that it responds to
  requests only when nc is given a corresponding -svrname argument.  By naming
  servers, you can run several simultaneously, and direct files and commands
  specifically to any one. Specifying a non-empty name automatically designates
  this session as an NEdit server, as though -server were specified.

**-import file**
  Loads an additional preferences file on top of the existing defaults saved in
  your preferences file.  To incorporate macros, language modes, and highlight
  patterns and styles written by other users, run NEdit with -import ,
  then re-save your preferences file with Preferences -> Save Defaults.

**-version**
  Prints out the NEdit version information. The -V option is synonymous.

**-help**
  Prints out the NEdit command line help. The -h option is synonymous.

**--**
  Treats all subsequent arguments as file names, even if they start with a
  dash. This is so NEdit can access files that begin with the dash character.

!!#endif /* VMS */
.. ~ help
   ----------------------------------------------------------------------

Client/Server Mode
------------------

  NEdit can be operated on its own, or as a two-part client/server
  application.  Client/server mode is useful for integrating NEdit with
  software development environments, mailers, and other programs; or just as a
  quick way to open files from the shell command line without starting a new
  NEdit session.

  To run NEdit in server mode, type:

      nedit -server

  NEdit can also be started in server mode via the NEdit Client program
  (**nc**) when no servers are available.

  The nc program, which is distributed along with NEdit, sends commands to
  an NEdit server to open files or execute editor actions. It can also be
  used on files that are already opened.

  Listing a file on the nc command line means: Open it if it is not already
  open and bring the window to the front.


  nc supports the following command line options:

    **nc** [**-read**] [**-create**]
       [**-line** n | **+**n] [**-do** command] [**-lm** languagemode]
       [**-svrname** name] [**-svrcmd** command]
       [**-ask**] [**-noask**] [**-timeout** seconds]
       [**-geometry** geometry | **-g** geometry] [**-icon** | **-iconic**]
       [-**tabbed**] [-**untabbed**] [-**group**] [**-wait**]
       [**-V** | **-version**]
       [**-xrm** resourcestring] [**-display** [host]:server[.screen]]
       [**-**-] [file...]

**-read**
  Open the file read-only regardless of its actual permissions. There is no
  effect if the file is already open.

**-create**
  Don't warn about file creation when a file doesn't exist.

**-line** n, **+**n
  Go to line number n. This will also affect files which are already open.

**-do** command
  Execute an NEdit macro or action on the file following the -do argument
  on the command line.

  If you use this command without a filename, nc would randomly choose one
  window to focus and execute the macro in.

**-lm** languagemode
  Initial language mode used.

**-svrname** name
  Explicitly instructs nc which server to connect to, an instance of
  nedit(1) with a corresponding -svrname argument.  By naming servers, you
  can run several simultaneously, and direct files and commands
  specifically to any one.

**-svrcmd** command
  The command which nc uses to start an NEdit server. It is also settable
  via the X resource `nc.serverCommand' (see X_Resources_). Defaults to
  "nedit -server".

**-ask**, **-noask**
  Instructs nc to automatically start a server if one is not available.  This
  overrides the X resource `nc.autoStart' (see X_Resources_).

**-timeout** seconds
  Basic time-out period used in communication with an NEdit server.  The
  default is 10 seconds. Also settable via the X resource `nc.timeOut'.

  Under rare conditions (such as a slow connection), it may be necessary to
  increase the time-out period. In most cases, the default is fine.

**-geometry** geometry, **-g** geometry
  The initial size and/or location of editor windows. See
  NEdit_Command_Line_ for details.

**-icon**, **-iconic**
  Initial window state.

**-tabbed**
  Open all subsequent files in new tabs. Resets -group option.

**-untabbed**
  Open all subsequent files in new windows. Resets -group option.

**-group**
  Open all subsequent files as tabs in a new window.

**-wait**
  Instructs nc not to return to the shell until all files given are closed.

  Normally, nc returns once the files given in its command line are opened
  by the server. When this option is given, nc returns only after the last
  file given in this call is closed.

  Note that this option affects all files in the command line, not only the
  ones following this option.

  Note that nc will wait for all files given in the command line, even if
  the files were already opened.

**-version**, **-V**
  Prints nc's version and build information.

**-xrm** resourcestring
  Contains the resourcestring passed to a newly started server. This option
  has no effect if the server is already started.

**-display** []:[.]
  The name of the X server to use. See NEdit_Command_Line_ for details.


4>Command Line Arguments

  In typical Unix style, arguments affect the files which follow them on the
  command line, for example:

      incorrect:   nc file.c -line 25
      correct:     nc -line 25 file.c

  -read, -create, and -line affect all of the files which follow them on the
  command line.

  The -do macro is executed only once, on the next file on the line.  -do
  without a file following it on the command line, executes the macro on the
  first available window (presumably when you give a -do command without a
  corresponding file or window, you intend it to do something independent of
  the window in which it happens to execute).

  The -wait option affects all files named in the command line.

4>Multiple Servers

  Sometimes it is useful to have more than one NEdit server running, for
  example to keep mail and programming work separate.  The option, -svrname, to
  both nedit and nc, allows you to start, and communicate with, separate named
  servers.  A named server responds only to requests with the corresponding
  -svrname argument.  If you use ClearCase and are within a ClearCase view, the
  server name will default to the name of the view (based on the value of the
  CLEARCASE_ROOT environment variable).

4>Communication

  Communication between nc and nedit is done through the X display. So as long
  as the X Window System is set up and working properly, nc will work properly
  as well. nc uses the DISPLAY environment variable, the machine name and your
  user name to find the appropriate server, meaning, if you have several
  machines sharing a common file system, nc will not be able to find a server
  that is running on a machine with a different host name, even though it may
  be perfectly appropriate for editing a given file.

  The command which nc uses to start an nedit server is settable via the X
  resource nc.serverCommand, by default, "nedit -server".
   ----------------------------------------------------------------------

Crash Recovery
--------------

  If a system crash, network failure, X server crash, or program error should
  happen while you are editing a file, you can still recover most of your
  work.  NEdit maintains a backup file which it updates periodically (every 8
  editing operations or 80 characters typed).  This file has the same name
  as the file that you are editing, but with the character `~' (tilde) on Unix
  or `_' (underscore) on VMS prefixed to the name.  To recover a file after a
  crash, simply rename the file to remove the tilde or underscore character,
  replacing the older version of the file.  (Because several of the Unix shells
  consider the tilde to be a special character, you may have to prefix the
  character with a `\' (backslash) when you move or delete an NEdit backup
  file.)

  Example, to recover the file called "help.c" on Unix type the command:

      mv \~help.c help.c

  A minor caveat, is that if the file you were editing was in MS DOS format,
  the backup file will be in Unix format, and you will need to open the backup
  file in NEdit and change the file format back to MS DOS via the Save As...
  dialog (or use the Unix unix2dos command outside of NEdit).

  GNU GENERAL PUBLIC LICENSE

  Version 2, June 1991

  Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
  Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
  verbatim copies of this license document, but changing it is not allowed.

  Preamble

  The licenses for most software are designed to take away your freedom to
  share and change it. By contrast, the GNU General Public License is intended
  to guarantee your freedom to share and change free software--to make sure the
  software is free for all its users. This General Public License applies to
  most of the Free Software Foundation's software and to any other program
  whose authors commit to using it. (Some other Free Software Foundation
  software is covered by the GNU Library General Public License instead.) You
  can apply it to your programs, too.

  When we speak of free software, we are referring to freedom, not price. Our
  General Public Licenses are designed to make sure that you have the freedom
  to distribute copies of free software (and charge for this service if you
  wish), that you receive source code or can get it if you want it, that you
  can change the software or use pieces of it in new free programs; and that
  you know you can do these things.

  To protect your rights, we need to make restrictions that forbid anyone to
  deny you these rights or to ask you to surrender the rights. These
  restrictions translate to certain responsibilities for you if you distribute
  copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether gratis or
  for a fee, you must give the recipients all the rights that you have. You
  must make sure that they, too, receive or can get the source code. And you
  must show them these terms so they know their rights.

  We protect your rights with two steps: (1) copyright the software, and (2)
  offer you this license which gives you legal permission to copy, distribute
  and/or modify the software.

  Also, for each author's protection and ours, we want to make certain that
  everyone understands that there is no warranty for this free software. If the
  software is modified by someone else and passed on, we want its recipients to
  know that what they have is not the original, so that any problems introduced
  by others will not reflect on the original authors' reputations.

  Finally, any free program is threatened constantly by software patents. We
  wish to avoid the danger that redistributors of a free program will
  individually obtain patent licenses, in effect making the program
  proprietary. To prevent this, we have made it clear that any patent must be
  licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and modification
  follow.

  GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
  MODIFICATION

  0. This License applies to any program or other work which contains a notice
  placed by the copyright holder saying it may be distributed under the terms
  of this General Public License. The "Program", below, refers to any such
  program or work, and a "work based on the Program" means either the Program
  or any derivative work under copyright law: that is to say, a work containing
  the Program or a portion of it, either verbatim or with modifications and/or
  translated into another language. (Hereinafter, translation is included
  without limitation in the term "modification".) Each licensee is addressed as
  "you".

  Activities other than copying, distribution and modification are not covered
  by this License; they are outside its scope. The act of running the Program
  is not restricted, and the output from the Program is covered only if its
  contents constitute a work based on the Program (independent of having been
  made by running the Program). Whether that is true depends on what the
  Program does.

  1. You may copy and distribute verbatim copies of the Program's source code
  as you receive it, in any medium, provided that you conspicuously and
  appropriately publish on each copy an appropriate copyright notice and
  disclaimer of warranty; keep intact all the notices that refer to this
  License and to the absence of any warranty; and give any other recipients of
  the Program a copy of this License along with the Program.

  You may charge a fee for the physical act of transferring a copy, and you may
  at your option offer warranty protection in exchange for a fee.

  2. You may modify your copy or copies of the Program or any portion of it,
  thus forming a work based on the Program, and copy and distribute such
  modifications or work under the terms of Section 1 above, provided that you
  also meet all of these conditions:

  a) You must cause the modified files to carry prominent notices stating
  that you changed the files and the date of any change.

  b) You must cause any work that you distribute or publish, that in whole or
  in part contains or is derived from the Program or any part thereof, to be
  licensed as a whole at no charge to all third parties under the terms of
  this License.

  c) If the modified program normally reads commands interactively when run,
  you must cause it, when started running for such interactive use in the
  most ordinary way, to print or display an announcement including an
  appropriate copyright notice and a notice that there is no warranty (or
  else, saying that you provide a warranty) and that users may redistribute
  the program under these conditions, and telling the user how to view a copy
  of this License. (Exception: if the Program itself is interactive but does
  not normally print such an announcement, your work based on the Program is
  not required to print an announcement.)

  These requirements apply to the modified work as a whole. If identifiable
  sections of that work are not derived from the Program, and can be reasonably
  considered independent and separate works in themselves, then this License,
  and its terms, do not apply to those sections when you distribute them as
  separate works. But when you distribute the same sections as part of a whole
  which is a work based on the Program, the distribution of the whole must be
  on the terms of this License, whose permissions for other licensees extend to
  the entire whole, and thus to each and every part regardless of who wrote it.

  Thus, it is not the intent of this section to claim rights or contest your
  rights to work written entirely by you; rather, the intent is to exercise the
  right to control the distribution of derivative or collective works based on
  the Program.

  In addition, mere aggregation of another work not based on the Program with
  the Program (or with a work based on the Program) on a volume of a storage or
  distribution medium does not bring the other work under the scope of this
  License.

  3. You may copy and distribute the Program (or a work based on it, under
  Section 2) in object code or executable form under the terms of Sections 1
  and 2 above provided that you also do one of the following:

  a) Accompany it with the complete corresponding machine-readable source
  code, which must be distributed under the terms of Sections 1 and 2 above
  on a medium customarily used for software interchange; or,

  b) Accompany it with a written offer, valid for at least three years, to
  give any third party, for a charge no more than your cost of physically
  performing source distribution, a complete machine-readable copy of the
  corresponding source code, to be distributed under the terms of Sections 1
  and 2 above on a medium customarily used for software interchange; or,

  c) Accompany it with the information you received as to the offer to
  distribute corresponding source code. (This alternative is allowed only for
  noncommercial distribution and only if you received the program in object
  code or executable form with such an offer, in accord with Subsection b
  above.)

  The source code for a work means the preferred form of the work for making
  modifications to it. For an executable work, complete source code means all
  the source code for all modules it contains, plus any associated interface
  definition files, plus the scripts used to control compilation and
  installation of the executable. However, as a special exception, the source
  code distributed need not include anything that is normally distributed (in
  either source or binary form) with the major components (compiler, kernel,
  and so on) of the operating system on which the executable runs, unless that
  component itself accompanies the executable.

  If distribution of executable or object code is made by offering access to
  copy from a designated place, then offering equivalent access to copy the
  source code from the same place counts as distribution of the source code,
  even though third parties are not compelled to copy the source along with the
  object code.

  4. You may not copy, modify, sublicense, or distribute the Program except as
  expressly provided under this License. Any attempt otherwise to copy, modify,
  sublicense or distribute the Program is void, and will automatically
  terminate your rights under this License. However, parties who have received
  copies, or rights, from you under this License will not have their licenses
  terminated so long as such parties remain in full compliance.

  5. You are not required to accept this License, since you have not signed it.
  However, nothing else grants you permission to modify or distribute the
  Program or its derivative works. These actions are prohibited by law if you
  do not accept this License. Therefore, by modifying or distributing the
  Program (or any work based on the Program), you indicate your acceptance of
  this License to do so, and all its terms and conditions for copying,
  distributing or modifying the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the Program),
  the recipient automatically receives a license from the original licensor to
  copy, distribute or modify the Program subject to these terms and conditions.
  You may not impose any further restrictions on the recipients' exercise of
  the rights granted herein. You are not responsible for enforcing compliance
  by third parties to this License.

  7. If, as a consequence of a court judgment or allegation of patent
  infringement or for any other reason (not limited to patent issues),
  conditions are imposed on you (whether by court order, agreement or
  otherwise) that contradict the conditions of this License, they do not excuse
  you from the conditions of this License. If you cannot distribute so as to
  satisfy simultaneously your obligations under this License and any other
  pertinent obligations, then as a consequence you may not distribute the
  Program at all. For example, if a patent license would not permit
  royalty-free redistribution of the Program by all those who receive copies
  directly or indirectly through you, then the only way you could satisfy both
  it and this License would be to refrain entirely from distribution of the
  Program.

  If any portion of this section is held invalid or unenforceable under any
  particular circumstance, the balance of the section is intended to apply and
  the section as a whole is intended to apply in other circumstances.

  It is not the purpose of this section to induce you to infringe any patents
  or other property right claims or to contest validity of any such claims;
  this section has the sole purpose of protecting the integrity of the free
  software distribution system, which is implemented by public license
  practices. Many people have made generous contributions to the wide range of
  software distributed through that system in reliance on consistent
  application of that system; it is up to the author/donor to decide if he or
  she is willing to distribute software through any other system and a licensee
  cannot impose that choice.

  This section is intended to make thoroughly clear what is believed to be a
  consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in certain
  countries either by patents or by copyrighted interfaces, the original
  copyright holder who places the Program under this License may add an
  explicit geographical distribution limitation excluding those countries, so
  that distribution is permitted only in or among countries not thus excluded.
  In such case, this License incorporates the limitation as if written in the
  body of this License.

  9. The Free Software Foundation may publish revised and/or new versions of
  the General Public License from time to time. Such new versions will be
  similar in spirit to the present version, but may differ in detail to address
  new problems or concerns.

  Each version is given a distinguishing version number. If the Program
  specifies a version number of this License which applies to it and "any later
  version", you have the option of following the terms and conditions either of
  that version or of any later version published by the Free Software
  Foundation. If the Program does not specify a version number of this License,
  you may choose any version ever published by the Free Software Foundation.

  10. If you wish to incorporate parts of the Program into other free programs
  whose distribution conditions are different, write to the author to ask for
  permission. For software which is copyrighted by the Free Software
  Foundation, write to the Free Software Foundation; we sometimes make
  exceptions for this. Our decision will be guided by the two goals of
  preserving the free status of all derivatives of our free software and of
  promoting the sharing and reuse of software generally.

  **NO WARRANTY**

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
  THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
  STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
  PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
  INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
  FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
  PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
  YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO
  LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR
  THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  POSSIBILITY OF SUCH DAMAGES.

Mailing Lists
-------------

  There are two separate mailing lists for nedit users, and one for developers.
  Users may post to the developer mailing list to report defects and communicate
  with the nedit developers.  Remember that nedit is entirely a volunteer
  effort, so please ask questions first to the discussion list, and do your
  share to answer other users questions as well.

    discuss@@nedit.org_

  General discussion, questions and answers among NEdit users and developers.

    announce@@nedit.org_

  A low-volume mailing list for announcing new versions.

    develop@@nedit.org_

  Communication among and with NEdit developers.
  Developers should also subscribe to the discuss list.

  To subscribe, send mail to one of the following addresses:

    announce-request@@nedit.org_
    discuss-request@@nedit.org_
    develop-request@@nedit.org_

  with the body consisting of the single word

Problems/Defects
----------------

3>Solutions to Common Problems

  For a much more comprehensive list of common problems and solutions, see the
  NEdit FAQ.  The latest version of the FAQ can always be found on the NEdit
  web site at:

      http://www.nedit.org_.

  **P: No files are shown in the "Files" list in the Open... dialog.**

  S: When you use the "Filter" field, include the file specification or a
  complete directory specification, including the trailing "/" on Unix.
  (See Help in the Open... dialog).

  **P: Find Again and Replace Again don't continue in the same direction as the original Find or Replace.**

  S: Find Again and Replace Again don't use the direction of the original
  search.  The Shift key controls the direction: Ctrl+G means forward,
  Shift+Ctrl+G means backward.

  **P: Preferences specified in the Preferences menu don't seem to get saved when I select Save Defaults.**

  S: NEdit has two kinds of preferences: 1) per-window preferences, in the
  Preferences menu, and 2) default settings for preferences in newly created
  windows, in the Default Settings sub-menu of the Preferences menu.
  Per-window preferences are not saved by Save Defaults, only Default
  Settings.

  **P: Columns and indentation don't line up.**

  S: NEdit is using a proportional width font.  Set the font to a fixed style
  (see Preferences menu).

  **P: NEdit performs poorly on very large files.**

  S: Turn off Incremental Backup.  With Incremental Backup on, NEdit
  periodically writes a full copy of the file to disk.

  **P: Commands added to the Shell Commands menu (Unix only) don't output anything until they are finished executing.**

  S: If the command output is directed to a dialog, or the input is from a
  selection, output is collected together and held until the command
  completes.  De-select both of the options and the output will be shown
  incrementally as the command executes.

  **P: Dialogs don't automatically get keyboard focus when they pop up.**

  S: Most X Window managers allow you to choose between two categories of
  keyboard focus models: pointer focus, and explicit focus.  Pointer focus
  means that as you move the mouse around the screen, the window under the
  mouse automatically gets the keyboard focus.  NEdit users who use this
  focus model should set "Popups Under Pointer" in the Default Settings sub
  menu of the preferences menu in NEdit.  Users with the explicit focus
  model, in some cases, may have problems with certain dialogs, such as Find
  and Replace.  In MWM this is caused by the mwm resource startupKeyFocus
  being set to False (generally a bad choice for explicit focus users).
  NCDwm users should use the focus model "click" instead of "explicit",
  again, unless you have set it that way to correct specific problems, this
  is the appropriate setting for most explicit focus users.

  **P: The Backspace key doesn't work, or deletes forward rather than backward.**

  S: While this is an X/Motif binding problem, and should be solved outside of
  NEdit in the Motif virtual binding layer (or possibly xmodmap or
  translations), NEdit provides an out.  If you set the resource:
  nedit.remapDeleteKey to True, NEdit will forcibly map the delete key to
  backspace.  The default setting of this resource recently changed, so
  users who have been depending on this remapping will now have to set it
  explicitly (or fix their bindings).

  **P: NEdit crashes when I try to paste text in to a text field in a dialog (like Find or Replace) on my SunOS system.**

  S: On many SunOS systems, you have to set up an nls directory before various
  inter-client communication features of Motif will function properly.
  There are instructions in README.sun in /pub/v5_0_2/individual/README.sun on
  ftp.nedit.org, as well as a tar file containing a complete nls
  directory: ftp://ftp.nedit.org/pub/v5_0_2/nls.tar.
  README.sun contains directions for setting up an nls directory, which
  is required by Motif for handling copy and paste to Motif text fields.

3>Known Defects

  Below is the list of known defects which affect NEdit. The defects your copy
  of NEdit will exhibit depend on which system you are running and with which
  Motif libraries it was built. Note that there are now Motif 1.2 and/or 2.0
  libraries available on ALL supported platforms, and as you can see below
  there are far fewer defects in Motif 1.2, so it is in your best interest to
  upgrade your system.

4>All Versions

**DEFECT**
  Operations between rectangular selections on overlapping lines do nothing.

~Work Around~
  None.  These operations are very complicated and rarely used.

**DEFECT**
  Cut and Paste menu items fail, or possibly crash,
  for very large (multi-megabyte) selections.

~Work Around~
  Use selection copy (middle mouse button click)
  for transferring larger quantities of data.
  Cut and Paste save the copied text in server
  memory, which is usually limited.

3>Reporting Defects

  Submit bugs through the web at:

    http://sf.net/tracker/?func=add&group_id=11005&atid=111005

  Please include the first few lines from Help > Version, which identifies
  NEdit's version and other system attributes important for diagnosing your
  problem.

  The NEdit developers subscribe to both discuss@@nedit.org and
  develop@@nedit.org, either of which may be used for reporting defects.  If
  you're not sure, or you think the report might be of interest to the general
  NEdit user community, send the report to discuss@@nedit.org_.  If it's
  something obvious and boring, like we misspelled "anemometer" in the on-line
  help, send it to develop@@nedit.org_.  If you don't want to subscribe to the
  Mailing_Lists_, please add a note to your mail about cc'ing you on responses.

.. =============================================================================

.. Below is what is used to guide the generation of 'C'-Motif menus.
.. Indentation is SIGNIFICANT in the "Menu" directive lines below. It
.. is used to determine under which menu element another item will belong.
.. The number of spaces indented is not significant, but items to be placed
.. in the same menu panel MUST line up at the same indent level.
.. ALL nodes of this menu "tree" should have help name qualifiers.
.. These are used to produce the internal lists used by NEdit help code.

.. By default, the first character of the menu element will be used as a
.. menu mneumonic key. To use another character in the menu element for this
.. purpose, surround the character with underscores (eg. I w_a_nt 'a').

.. The menu title MUST match the one found in the actual help text (sans
.. special mneumonic key character marking). The help text title may include
.. underlines (for spaces) when it is a hyperlink target.

.. The Help-name is used to generate various data structure names. For
.. instance, the 'start' help name will be used to generate the HelpTopic
.. enumeration value HELP_START and the character array htxt_start which
.. holds the actual help text used in the menu dialogs. Consequently, these
.. names need to be unique and contain only the characters that a 'C'
.. compiler can digest.

.. Menu separator lines use a dash (-) character for the Menu Title. They
.. should also have a unique Help-name.

.. A numerical value following the Help-name (separated from the name by
.. a comma and/or spaces) is part of a menu element hiding scheme implemented
.. in buildHelpMenu (found in 'menu.c'). When the number matches the hideIt
.. value found in the procedure, that element will effectively become invisible.
.. This mechanism was created for particular menu features that are not
.. available to all incarnations of NEdit (in this case, the VMS version).

.. A "Help" directive is used for all other text used as NEdit help, but
.. does not show up in the Help menu.

=head1 NAME

nc - Client program for NEdit text editor

=head1 SYNOPSYS

nc [B<-read>] [B<-create>] [B<-line> I | B<+>I] [B<-do> I] 
   [B<-ask>] [B<-noask>] [B<-svrname> I] [B<-svrcmd> I] 
   [B<-lm> I] 
   [B<-geometry> I | B<-g> I] [B<-icon> | B<-iconic>] 
   [B<-display> I<[host]:server[.screen]>] 
   [B<-timeout> I] [B<-wait>] [B<-xrm> I] 
   [B<-tabbed>] [B<-untabbed>] [B<-group>] 
   [B<-V> | B<-version>] [B<-h> | B<-help>] [B<-->] [file...]

=head1 DESCRIPTION

B is the client interface to the NEdit text editor. A server can be started
explicitly by running NEdit in server mode:

 nedit -server

If no server is running, B will start one unless configured otherwise.
Client/server mode is useful for integrating NEdit with software development
environments, mailers, and other programs; or just as a quick way to open files
from the shell command line without starting a new NEdit session.

=head1 OPTIONS

=over

=item  B<-read>

Open the file read-only regardless of the actual file protection.

=item  B<-create>

Don't warn about file creation when a file doesn't exist.

=item  B<-line> I, B<+>I

Go to line number I.

=item  B<-do> I

Execute an NEdit macro or action on the file following the -do argument on the
command line.

If you use this command without a filename, B would randomly choose one
window to focus and execute the macro in.

=item  B<-ask>, B<-noask>

Instructs B whether to automatically start a server if one is not
available. This overrides the X resource `nc.autoStart'.


=item  B<-svrname> I

Explicitly instructs B which server to connect to, an instance of
L with a corresponding B<-svrname> argument.  By naming servers, you
can run several simultaneously, and direct files and commands specifically to
any one.

=item  B<-svrcmd> I

The command which B uses to start an NEdit server. It is also settable via
the X resource `nc.serverCommand', by default, I<"nedit -server">.

=item  B<-lm> I

Initial language mode used for editing succeeding files.

=item  B<-geometry> I, B<-g> I

The initial size and/or location of editor windows. The argument geometry has
the form:

  [x][+|-][[+|-]]

where `' and `' are the desired width and
height of the window, and `' and `' are the
distance from the edge of the screen to the window, + for top or left, - for
bottom or right. B<-geometry> can be specified for individual files on the
command line.

=item  B<-icon>, B<-iconic>

Initial window state for succeeding files.

=item  B<-display> I<[host]:server[.screen]>

The name of the X server to use. host specifies the machine, server specifies
the display server number, and screen specifies the screen number.  host or
screen can be omitted and default to the local machine, and screen 0.

=item  B<-timeout> I

Basic time-out period (in seconds) used in communication with an NEdit server.
Default: 10 seconds. Also settable via the X resource `nc.timeOut'.

Under rare conditions (such as a slow connection), it may be necessary to
increase the time-out period. In most cases, the default is fine. 

=item B<-wait>

Instructs B not to return to the shell until all files given
are closed.

Normally, B returns once the files given in its command line
are opened by the server. When this option is given, nc returns
only after the last file given in this call is closed.
Note that this option affects all files, not only the ones
following this option in the command line.


=item  B<-xrm> I 

Set the value of an X resource to override a default value.

=item  B<-tabbed>

Open all subsequent files in new tabs. Resets B<-group> option.

=item  B<-untabbed>

Open all subsequent files in new windows. Resets B<-group> option.

=item  B<-group>

Open all subsequent files as tabs in a new window.


=item  B<-V>, B<-version> 

Prints version and build information, to be mentioned when reporting bugs and
problems. 

=item  B<-h>, B<-help> 

Prints the command line help and then exits.

=item B<-->

Treats all subsequent arguments as file names, even if they start with a dash.
This is so NEdit can access files that begin with the dash character. 


=back

=head1 ENVIRONMENT

=over

=item  DISPLAY

NEdit requires an X-based workstation or X-Terminal. If you have used B
or B to access the host Unix system, set the Unix environment variable
for your display:

    % setenv DISPLAY devicename:0

=back

=head1 NOTES

Communication between L and L is through the X display. So as
long as X windows is set up and working properly, B will work properly
as well. B uses the `DISPLAY' environment variable, the machine name and
your user name to find the appropriate server, meaning, if you have several
machines sharing a common file system, B will not be able to find a server
that is running on a machine with a different host name, even though it may be
perfectly appropriate for editing a given file.

In typical Unix style, arguments affect the files which follow them on the
command line, for example:

=over

=item  incorrect:

  nc file.c -line 25

=item  correct:

  nc -line 25 file.c

=back

distribution kit.

=head1 DESCRIPTION

NEdit is a standard GUI (Graphical User Interface) style text editor for
programs and plain-text files. It provides mouse based editing and a
streamlined editing style, based on popular Macintosh and MS Windows editors,
for users of X workstations and X terminals.

=head1 OPTIONS

=over 

=item  B<-read> 

Open the file read-only regardless of the actual file protection.

=item  B<-create> 

Don't warn about file creation when a file doesn't exist.

=item  B<-line> I, B<+>I 

Go to line number I.

=item  B<-server> 

Designate this session as an NEdit server, for processing commands from the
L program. L can be used to interface NEdit to code development
environments, mailers, etc., or just as a quick way to open files from the
shell command line without starting a new NEdit session.

=item  B<-do> I 

Execute an NEdit macro or action on the file following the -do argument on the
command line. B<-do> is particularly useful from the L program, where
`nc -do' can remotely execute commands in an nedit B<-server> session.

=item  B<-tags> I 

Load a file of directions for finding definitions of program subroutines and
data objects. The file must be of the format generated by Exuberant Ctags, or
the standard Unix L command.

=item  B<-tabs> I 

Set tab stops every I characters.

=item  B<-wrap>, B<-nowrap> 

Wrap long lines at the right edge of the window rather than continuing them
past it. (Continuous Wrap mode)

=item  B<-autowrap>, B<-noautowrap> 

Wrap long lines when the cursor reaches the right edge of the window by
inserting newlines at word boundaries. (Auto Newline Wrap mode)

=item  B<-autoindent>, B<-noautoindent> 

Maintain a running indent.

=item  B<-autosave>, B<-noautosave> 

Maintain a backup copy of the file being edited under the name I<~filename> 
(on Unix) or I<_filename> (on VMS).

=item  B<-lm> I 

Initial language mode used for editing succeeding files.

=item  B<-rows> I 

Default height in characters for an editing window.

=item  B<-columns> I 

Default width in characters for an editing window.

=item  B<-font> I, B<-fn> I 

Font for text being edited. Font for menus and dialogs can be set with B<-xrm>
I<"*fontList:font">.

=item  B<-geometry> I, B<-g> I 

The initial size and/or location of editor windows. The argument geometry has
the form:

  [x][+|-][[+|-]]

where C`' and C<<  >> are the desired width and
height of the window, and  and C`' are the
distance from the edge of the screen to the window, + for top or left, - for
bottom or right. B<-geometry> can be specified for individual files on the
command line.

=item  B<-iconic>, B<-noiconic> 

Initial window state for succeeding files.

=item  B<-display> I<[host]:server[.screen]> 

The name of the X server to use. I specifies the machine, I
specifies the display server number, and I specifies the screen number.
I or I can be omitted and default to the local machine, and
screen 0.

=item  B<-background> I, B<-bg> I 

Background color. The background color for text can be set separately with
B<-xrm> I<"nedit*text.background: color">.

=item  B<-foreground> I, B<-fg> I 

Foreground color. The foreground color for text can be set separately with
B<-xrm> I<"nedit*text.foreground: color">.

=item  B<-xrm> I 

Set the value of an X resource to override a default value.

=item  B<-svrname> I 

When starting nedit in server mode, name the server, such that it responds to
requests only when L is given a corresponding B<-svrname> argument. By
naming servers, you can run several simultaneously, and direct files and
commands specifically to any one. Specifying a non-empty name automatically
designates this session as an NEdit server, as though B<-server> were specified.

=item  B<-import> I 

Loads an additional preferences file on top of the existing defaults saved in
your I file.  To incorporate macros, language modes, and highlight
patterns and styles written by other users, run nedit with B<-import>
I<>, then re-save your I file with
Preferences->Save Defaults.

=item  B<-tabbed>

Open all subsequent files in new tabs. Resets B<-group> option.

=item  B<-untabbed>

Open all subsequent files in new windows. Resets B<-group> option.

=item  B<-group>

Open all subsequent files as tabs in a new window.

=item  B<-V>, B<-version> 

Prints version and build information, to be mentioned when reporting bugs and
problems. 

=item  B<-h>, B<-help> 

Prints the command line help and then exits.

=item B<-->

Treats all subsequent arguments as file names, even if they start with a dash.
This is so NEdit can access files that begin with the dash character. 

=back

=head1 ENVIRONMENT

=over

=item  DISPLAY

NEdit requires an X-based workstation or X-Terminal. If you have used  B
or B to access the host Unix system, set the Unix environment variable for
your display:

csh-type shells:

   % setenv DISPLAY devicename:0

sh-type shells:

   % DISPLAY=devicename:0 && export DISPLAY

=item NEDIT_HOME

This environment variable can be set to the name of a
directory. This directory will then be used instead of
`$HOME/.nedit' as the base directory for NEdit's special
files (see section FILES, below).

This variable is new to NEdit 5.4.

=back

=head1 FILES

From version 5.4 on, NEdit creates a directory in which NEdit's
special files reside. This directory is named '.nedit' by default.

=over

=item I

This is an X resource file which contains most user settings for
NEdit. It is read at startup and written by selecting the item
'Save Defaults...' in the Preferences menu. Do not edit this
file by hand, all settings can be reached via the 'Default
Settings' menu.

=item I

The list of recently opened files. Do not edit this
file by hand.

=item I

A file that can contain a number of NEdit Macro Language
statements and subroutine definitions. The statements will be
executed when an NEdit server starts, the subroutines will be
loaded for later reference.
This file will not be created or modified by NEdit (unless
you load it and edit it of course).

=back
                                       

Note that NEdit still supports the older names for these files,
which were used by version 5.3 and below. These file names
are `$HOME/.nedit', `$HOME/.neditdb' and `$HOME/.neditmacro',
respectively. The old naming scheme will be used if NEdit
detects that `$HOME/.nedit' is a regular file and NEDIT_HOME 
isn't set.

See also the entry for NEDIT_HOME under ENVIRONMENT, above.

=head1 NOTES

For more information see NEdit's online help, or nedit.doc in the NEdit
distribution kit.

# The concept of setext documents is the brain child of Ian Feldman.
# Some typotag terms used herein were originally implemented in a perl script
# by Tony Sanders, which is the inspirational source for this work.
# This perl script understands the original typotags, plus extras needed for 
# hypertext links, conditional text, and variables.
#
# Samples of setext documents are regularly provided to those folks which
# receive the TidBITS publication from www.tidbits.com in their e-mail.
#
# This program is really two programs crammed into one file. The two separate
# pieces share lots of code. Instead of having 3 separate files, one of
# them being a perl library with the shared code, there was a desire to keep
# everything rolled up in one suitcase.

 ============  ===================  ==================

 Only one instance of the element subhead-tt (or, in its
 absence, title-tt) is absolutely _required_ for a text to
 be considered a valid setext.

 All the elements, but subhead-tt, are in effect optional,
 that is, not necessary for a setext to be declared as
 such. The target-tt element allows the hypertext link
 definition of href-tt to be within the same setext. The
 actual reference (href-tt) of the target would look like:

    .. _word #reference_within_document

!Multiple line maybe[not]-tt (conditional text regions)
!are introduced as ".. ? name~" or ".. ! name~" and are
!terminated with ".. ~ name", on a separate line. Single
!line maybe[not]-tt do not use the '~' character and are
!terminated with the end of the line. The special
!conditional text region named "html" allows a mixture of
!setext and HTML tags. Nesting of these typotags is
!allowed. For instance, if there are three conditional
!regions, A, B, and C, C can be nested inside B, which can
!be nested inside A (eg. A-B-C...C-B-A). Note that a
!surrounding region cannot end before one of its inner
!regions is terminated (eg. of illegal nesting
!A-B-C...C-A-B, where A terminated prior to B.

 Multiple line list-tt are introduced as ".(". Each line
 belongs to the current list element until an empty line
 is encountered. Once a list-tt is encountered, line
 separated paragraphs constitute list elements.  A list-tt
 is terminated by endlist-tt. The list-tt/endlist-tt
 typotags are allowed to be nested (unlike the bullet-tt).
 These typo-tags do not have to start in the first column
 of a line, but must have leading whitespace if they are
 indented at all.

 Field typotags are used to define and reference values.
 Field definitions can only occur within a suppress-tt.
 For example:  "..  `|>author=Steven Haehn<|`"
 Field references (eg. |>author<|) can occur in any 
 printable text. If there is no known value for the 
 field, it will remain unchanged and appear as written
 in the setext.

=head1 NAME

Setext - convert Structured Enhanced TEXT into HTML or plain text.

=head1 SYNOPSIS

 Usage: setext [ -dhtTVw ][-D directory][-H [hfile]][-S [htmlExt]] \
               [-c conditional][-v name=value][setext_file [converted_file]]

        setext {-mp} [-c conditional][-M menuSuffix][-v name=value] setext_file

  The first form of setext is used to convert Structure Enhanced TEXT
  documents into HTML or simple text documents.
  The second form is specific to generating NEdit help menu code
  from a setext document with Menu and Help directives.

  -c conditional text definitions, separated by commas.
  -d do not automatically make titles hypertext references (HTML only)
  -D specify destination directory for separate HTML files. This also sets
     the value for the variable HTML_DIR.
  -h show this usage clause.
  -H convert setext_file to HyperText Markup Language (HTML).
     Optional file parameter specifies file containing HTML header
     and footer definition overrides. The current defaults are:
        $htmlHeader = 
                      $HTML_TITLE
                      
                      
        $htmlFooter = 
                      
     where $HTML_TITLE is replaced with an appropriate title.

  -m generate NEdit help menu code files.
  -M name NEdit help code files with this suffix.
  -p do option -m and print out NEdit help elements.
  -S convert setext_file into separate HTML files.
     (the default name extension is 'html', but it can be
     changed by specifying it as an argument to this option)
  -t convert setext_file to simple text (default).
  -T emit setext typotag definitions in use.
  -v defines variable name and assigns it the given value.
     (more than one occurrence of -v can be made) The variables
     are made available for use within the setext document parsing.
  -V display the version of this setext script.
  -w do not emit warnings about missing variables.

  When the converted_file argument is missing, STDOUT is used.
  When the setext_file argument is missing, STDIN is used.

  To get conditional text within a setext document to be displayed,
  supply a definition tag through the -c option. For example,

          setext -c NEDITDOC help.etx nedit.doc

  would generate a plain text document, nedit.doc, from the source
  help.etx, including/excluding text marked with 'NEDITDOC'
  conditional text markers, also known as 'maybe' typotags.

=head1 DESCRIPTION

This Structured Enhanced TEXT converter produces either HTML or plain
text files from a given setext source. The HTML files produced can
include hypertext references to within itself, or to external 
destinations. The setext converter also has the capability of providing
different content in the resulting output files through a conditional 
text mechanism, and variable data definitions. All this allows a 
publisher to maintain a single, very readable, source while producing
varying content for different output formats and audiences.

When the converted_file argument is missing, STDOUT is used.
When the setext_file argument is missing, STDIN is used. This gives
setext the capability of being a filter to other programs.

To get conditional text within a setext document to be displayed,
supply a definition tag through the -c option. For example,

        setext -c NEDITDOC help.etx nedit.doc

would generate a plain text document, nedit.doc, from the source
help.etx, including/excluding text marked with 'NEDITDOC'
conditional text markers, also known as 'maybe' typotags.

Use the -T option to see the set of typotags supported by this
converter. Further explanations of typotags occurs there.

=head2 HTML Generation Examples

The simplest form of HTML generation is:

        setext help.etx nedit.html
        setext -H help.etx nedit.html

The results will be stored in the current directory in the nedit.html
file.

When the user wants to break up the resulting html file into multiple
files, with cross references between the files, the -S option should
be used.

        setext -S help.etx nedit.html

The resulting files are broken up according to titled sections and 
are placed into the current directory, along with the nedit.html file.

To change the destination of the resulting files, two options are
supplied, the -D and -S options. For instance,

        setext -S shtml -D help/nedit help.etx nedit.shtml

The -S option allows the name of the file extension to be altered.
The -D option specifies where the resulting files are going to be
stored. Thus, in the example, all the files will be placed in the
help/nedit directory (relative to the current directory) and will
have ".shtml" as the file extension.

A final nuance has been added to help server side HTML capabilities.
The -H option can be used to specify a file which contains the
definitions of $htmlHeader and $htmlFooter. This will be used to
override that which is supplied by the setext script. For example,

        setext -S shtml -H NEdit.ssd help.etx nedit.html

tells setext to use the file NEdit.ssd (server side definition) 
to override the HTML header and footer generation. An example of
the contents of this file follows.

    $htmlHeader = 
      '' . "\n" .
      '' . "\n";

    $htmlFooter =  
       '' . "\n";

=head2 NEdit Help Menu

When generating the NEdit help menu code, two files will be produced,
help_data.h and help_topic.h (when the -M option is not used).
These two files contain all the programmatic
data needed to implement hypertext menus within the NEdit program.
The following is an example of a setext invocation which assumes that
the variable 'version' is being used within the help.etx file.

        setext -m -v "version=6.0" help.etx

If the -M option is used, its value is appended to the root portion
of the two generated files. For example,

        setext -m -c VMS -M _VMS help.etx

will generate the files help_topic_VMS.h and help_data_VMS.h. The 
conditional portion of the help menu specifically designated for VMS 
will be extracted from the help.etx source.

Below is what is used to guide the generation of 'C'-Motif menus.
Indentation is SIGNIFICANT in the "Menu" directive lines below. It
is used to determine under which menu element another item will belong.
The number of spaces indented is not significant, but items to be placed
in the same menu panel MUST line up at the same indent level.
ALL nodes of this menu "tree" should have help name qualifiers.
These are used to produce the internal lists used by NEdit help code.

By default, the first character of the menu element will be used as a 
menu mneumonic key. To use another character in the menu element for 
this purpose, surround the character with underscores (eg. I w_a_nt 'a').

The menu title MUST match the one found in the actual help text (sans
special mneumonic key character marking). The help text title may include
underlines (for spaces) when it is a hyperlink target.

The Help-name is used to generate various data structure names. For
instance, the 'start' help name will be used to generate the HelpTopic
enumeration value HELP_START and the character array htxt_start which
holds the actual help text used in the menu dialogs. Consequently, these
names need to be unique and contain only the characters that a 'C'
compiler can digest.

Menu separator lines use a dash (-) character for the Menu Title. They
should also have a unique Help-name.

A numerical value following the Help-name (separated from the name by
a comma and/or spaces) is part of a menu element hiding scheme implemented
in buildHelpMenu (found in 'menu.c'). When the number matches the hideIt
value found in the procedure, that element will effectively become invisible.
This mechanism was created for particular menu features that are not
available to all incarnations of NEdit (in this case, the VMS version).

A "Help" directive is used for all other text used as NEdit help, but
does not show up in the Help menu. The following is a sample of
Menu and Help directives.

  What is setext
----------------

  The following is extracted from text written by Ian Feldman.
  
  As originally explained in TidBITS#100 and mentioned there from 
  now on, that publication now comes "wrapped as a setext." The noun
  itself stands for both a method to wrap (format) texts according 
  to specific layout rules and for a single _structure_enhanced_
  text.  The latter is a text which has been formatted in such a
  fashion that it contains clues as to the typographical and logical
  structure of its source (word-processed) document(s), if any.
  Those clues, which are called "typotags," facilitate later automatic
  detection of that structure so it can be validated, extracted,
  processed, transformed, enhanced as needed, if needed.

  It follows that setexts, being nothing but pure text (albeit with a
  special layout), are eminently readable using ANY editor or word
  processor in existence today or tommorrow, on any computer with a
  computer program that is capable of opening and reading text files. 
  By default all properly setext-ized files will have an ".etx" or
  ".ETX" suffix.  This stands for an "emailable/ enhanced text", the
  ExtraTerrestrial overtones nothwistanding ;-))

  Unlike other forms of text encoding that use explicit, visible tag
  elements such as  and <\that>, the setext format relies
  solely on the presence of _implicit_ typotags, carefully chosen
  to be as visually unobtrusive as possible.  The underlined word
  above is one such instance of the defacto "invisible" coding. 
  Inserted typotags will at worst appear as mere "typos" in the text.

  [Extensions made to the original set of typotags have muddied this
  clarity a little bit, but they were necessary for NEdit development.]

  Similarly, just to give an example, here is a short description
  of the four types of word emphasis typotags that setexts MAY
  contain, limited to one emphasis type ONLY per word or word group:

 -------------------  ----------------------------  --------------
!      **aBoldWord**  **multiple bold words**       ; bold-tt
!_anUnderlinedWord_    _multiple_underlined_words_  ; underline-tt
!    ~anItalicWord~    ~multiple italicized words~  ; italic-tt
!         aHotWord_     multiple_hot_words_         ; hot-tt 
 ----------------------------------------------------------------- 

 What makes a setext?
---------------------

  Before any decoding can take place a text has first to be
  verified whether it is a setext and not some arbitrarily-wrapped
  stream of characters.  Although there are more ways than one to
  achieve that goal there is one _primary_ test that has to be
  passed with colors or else the text being tested cannot be a
  setext. 

  Chief among the typotags are two that signal presence of setext
  titles and subheads inside the text.  A setext document can be
  formatted more or less properly, may contain or lack any other of
  its "native" elements but it has to have at least one proper
  subhead or a title in order to be declared as "a certified
  setext."

    Column 1 of text line
    |
    V
    Here are a few demo setext subheads:     
    ------------------------------------

    _ _ _ _ Which Share Just One _ _ _ _
    ------------------------------------

            ----------> UnifyinG FeaturE
    ------------------------------------

    of EQUAL RIGHTMOST VISIBLE character 
    ------------------------------------

      length as that of its subhead-tt's    
    ------------------------------------

    [this line is called subhead-string]
    ------------------------------------

    [the one below is called subhead-tt]
    ------------------------------------

    [together they make a valid subhead]
    ------------------------------------

       (!) and of course, subheads do not have to be of the same length ;-)
    -----------------------------------------------------------------------

      (nor have to begin in column 1)    
    ---------------------------------

     although it is recommended that they stay below 40 characters
    --------------------------------------------------------------

        Second Setext In This File
    ==============================

     ((end of examples))
     -------------------
     ((_not_ a subhead))
    ^
    |
    Column 1 of text line

  Note, the last 3 lines of the examples do not constitute a valid
  subhead because they do not start in column 1.

  Chief among the reasons why one should first look for presence of
  subheads rather than titles is that it is fully conceivable that a
  setext might have been created without an explicit title-tt in
  order to allow decoder programs to distinguish between part one
  and any subsequent ones in a possible multi-part mailing. This
  absence of a title-tt could be enough of a signal to start looking
  for possible "part x of y" message in either the subject line,
  filename or anywhere "above" the first detected subhead of the
  current text. 

  Therefore, here's a formal definition of what makes a setext:

 +-------------------------------------------------------------+
 |  a text that contains at least one verified setext subhead  |
 |  or setext title                                            |
 +-------------------------------------------------------------+

 Other considerations
---------------------

  A possibility arises to keep the paragraph text unwrapped, rather
  than folded uniformly at say the 66th character mark.  After all,
  if the setext is primarily to be displayed inside an editor,
  rather than on an 80 character terminal screen, then there is not
  much sense in prior folding of the lines to a specific
  guaranteed-to-fit-on-a-TTY-screen length.  The editor/word
  processor program will fit the unwrapped text to the available
  display area, and might actually prefer to have to deal with
  whole unwrapped paragraphs rather than with otherwise relatively
  short lines. 

  Most text-processing programs with native word-wrap capabilities
  actually consider return-terminated lines to be paragraphs in
  their own right.  Thus, if a setext is not to travel via email
  anyway (because of it being distributed differently or making use
  of accented characters) then it might as well arrive in unfolded
  state so that no extra time need be spent on making the
  paragraphs "whole again." [This is not the choice that is taken
  with NEdit help because it is easier to visualize the final text
  for those who do not use text wrapping.] 
  
  Observe that it is not the state of the paragraph text that makes
  or breaks a setext.  No, the sole criterion of whether a text is
  a setext is the presence of at least one verified subhead, as
  described above. Thus even texts with unfolded paragraphs are
  setexts if they contain at least one subhead-tt.

  The sole mechanism used in setext to encode which of such lines
  are in reality paragraphs (as opposed to those that shouldn't be
  folded mechanically) is the character indent.  In fact, after the
  subhead-tt the second most important typotag is the indent-tt,
  made up of exactly two space characters, which denotes any such
  indented lines as ready-candidates for reflowing by so inclined
  front-ends (either on their own or as part of like-indented lines
  above and below it).  So any potentially long line of a setext
  that has been indent-tted will be understood (by any validated
  setext front-end) as to be ready for wrapping-to-length if so
  required.

Typotags Available
------------------

  The following table contains typotags recognized by the setext
  utility. The "setext form" column in the table is formatted such
  that the left most character of the column represents the first
  character in a line of setext. The circumflex character (^) means
  that the characters of the typotag are significant only when they
  are anchored to the front of the setext line. Typotags marked
  with an asterisk (*) are extensions added for NEdit help
  generation.

  The title-tt, subhead-tt and indent-tt have already been
  discussed in length in the previous sections. All typotag
  elements, but the subhead-tt, are optional, that is, not
  necessary for a setext to be declared as such. The simple
  character marking typotags, bold-tt, italic-tt, and underline-tt
  have been used throughout the document and are used to mark text
  with their obvious meanings.

3>Section-tt (document divisions)

  The section-tt allows subdividing of the setext into further
  subsections for greater nesting capability. Typical usage starts
  the numbering level at 3 because the title-tt and subhead-tt
  basically represent sections 1 and 2, respectively.

3>Bullet-tt (list marker)

  The bullet-tt typotag is use to create a list of items. Note that
  it can only be used to create single line entries, like the
  following:
  
    Column 1 of text line
    |
    V
    * This is the first bullet.
    * This is the second bullet.
  
  Remember that you have to insert empty lines immediately before
  and after the bullet list.

3>Untouch-tt, Notouch-tt, Passthru-tt, Escape-tt (quoting text)

  Each one of these leave-my-text-alone typotags offer varying
  degrees of operation. The untouch-tt surrounds the text that
  is not to be interpreted. The accent grave (`) character is
  used to start and finish the untouchable text. (An extension
  to this has been allowed in the setext utility. An untouch-tt
  may be terminated by an apostrophe (').) The following are
  all valid untouch-tt typotags.
  
    `this is the _original_ version of the untouch-tt`
    `this is the _extended_ form of the untouch-tt'
    `This couldn't _be_ a problem could it?'

  Note that the third example has used the contraction "couldn't"
  which did not terminate the untouch-tt because the apostrophe was
  not followed by whitespace or punctuation.
  
  The notouch-tt typotag is used to take care of entire lines of
  text. The difference between this and the untouch-tt is that there
  is no visual residual typotag mark left in the output. It is
  replaced by a space. For example,
  
    Column 1 of text line
    |
    V
    ! This line of text will look like this sans the ! in column 1.

  becomes,
  
      This line of text will look like this sans the ! in column 1.

  The difference between the passthru-tt and the notouch-tt is
  the subtle difference of not replacing the markers with space, but
  totally removing them. (The original usage was to try to emit
  special 'C' compiler directives directly into the help code
  product). Thus,
  
    Column 1 of text line
    |
    V
    !!#ifdef VMS

  would turn into
  
    #ifdef VMS
  
  The escape-tt (@) is used to escape the special markers of 
  the other typotags and itself. Here is an example of escaping
  itself.
  
    develop@@nedit.org

  This will become "develop@nedit.org" in resulting documents.
  

3>Suppress-tt, Twodot-tt (author annotations or comments)

  The suppress-tt typotag allows an author to place annotations in a
  setext document which will not appear in a generated product. Most
  of the extensions to the original setext definition were placed
  inside this form of typotag.
  
    Column 1 of text line
    |
    V
    .. This is a document comment that would normally disappear
    .. from generated text, html, or the like. These lines are
    .. what constitute a suppress-tt. The following line is the
    .. twodot-tt.
    ..
    
3>Hot-tt, Href-tt, Target-tt (hyperlinking text)

  These three typotags are used in conjunction to create
  hypertext reference mechanism used int HTML and NEdit
  help code generation. The hot-tt is an original typotag which
  needed the additional two tags to be able create actual hyperlinks
  to other sections of the document, or to external references that
  could be exploited. These tags are ignored (stripped) when
  generating simple text documents.
  
  The hot-tt typotag is used to mark the text which would be used as
  the doorway to accessing other parts of the document. It either
  references a title or subhead string directly, or an href-tt. An
  href-tt (hypertext reference typotag) is used as an intermediary
  for the hyperlink destination. Its value either specifies an
  external document reference, or an internal document reference.
  The target-tt is used to mark the internal document references
  mentioned in a href-tt.
  
  Now for some examples. All the marked text will be inside
  parenthesis so it will stand out as to what explicitly is being
  marked. 
  
  This hot-tt directly references the (Typotags_Available_)
  subheading above. Whereas, the following hot-tt (references_) 
  the href-tt marked by this target-tt (_typotag).

  Here is what the href-tt would look like:
  
    Column 1 of text line
    |
    V
!   .. _references #typotsg

.. The following line is the actual hypertext reference in this
.. document. This annotation is an example of supress-tt usage. 
.. _references #typotag

3>Maybe[not]-tt, Endmaybe-tt (conditional text regions)

  Multiple line maybe-tt or maybenot-tt (conditional text regions)
  are introduced as follows:

    Column 1 of text line
    |
    V
    .. ? name~   (this is the maybe-tt)
    .. ! name~   (this is the maybenot-tt)
    
  Both are terminated with an endmaybe-tt on a separate line.

    Column 1 of text line
    |
    V
    .. ~ name

  The name* of the conditional region is left up to the text
  author.  Single line maybe[not]-tt typotags do not use the '~'
  character at the end of the name and are terminated at the end
  of the line. 

    Column 1 of text line
    |
    V
    .. ? oneLine (This is a one line maybe-tt)
    .. ! oneLine (This is a one line maybenot-tt)
  
  * There are some predefined conditional region names that are
  already known to the setext parser: html, text, and (NEdit) help.
  The special conditional text region named "html" allows a mixture
  of setext and HTML tags.

  Nesting of conditional text regions is allowed. For instance, if
  there are three conditional regions, A, B, and C, C can be nested
  inside B, which can be nested inside A. For example,
  A-B-C...C-B-A. 

      Column 1 of text line
    |
    V
    .. ? A~    Example of legally nested conditional text regions
    .. ? B~
    .. ? C~
    .. ~ C
    .. ~ B
    .. ~ A
  
  Note that a surrounding region cannot end before one of its inner
  regions is terminated (eg. of illegal nesting A-B-C...C-A-B,
  where A terminated prior to B).

3>Field-tt (variable definition and substitution)

  Field-tt typotags are used to define variables and reference
  their values. Field definitions can only occur within a
  suppress-tt.

  For example, to define the variable 'author' and fill it
  with the value "Steven Haehn":
 
      Column 1 of text line
    |
    V
    .. |>author=Steven Haehn<|

  To use the value of the defined variable, place the field-tt,
  |>author<|, in any printable text region. If there is no known
  value for the  field, it will remain unchanged and appear as
  written in the setext.

  The following are predefined for use in a field-tt
  for any setext document translated by the setext utility.

    Date =          (eg. December 6, 2001)
    date =  (eg. Dec 6, 2001)
    year =                         (eg. 2001)

3>Line-tt (horizontal rule demarcation)

  This typotag is used to place horizontal markers into generated
  text documents. Like the following.

   Column 4 of text line
   |
   V
   -------------------------------------------------------------  

3>Twobuck-tt (setext termination marker)

  This typotag is used to mark the end of document parsing.

# Prototype System-Specific Makefile for NEdit
#
# NEdit does not use any kind of automated configuration like the popular GNU
# configure utility, or Imake. Instead, it has a set of hand-generated
# system-specific Makefiles.  The Makefiles serve two purposes.  The obvious
# purpose is to build NEdit.  The less obvious purpose is to document on which
# systems effort has been put into verifying that NEdit actually works properly.
# If your system is not represented here, check the nedit web site at:
# http://nedit.org for more contributed Makefiles.
#
# NEdit has few dependencies, and sticks to Posix and ANSI C standards wherever
# possible.  The only problems people generally run in to in porting NEdit are
# related to the Motif GUI library. If you're having trouble building NEdit,
# usually the best way to get it to work is to look at any other Motif, or at
# least X example which builds and runs successfully, and copy the compiler
# flags and libraries that it uses.
#

# C Compiler used to build all of the C sources.  This must be an
# ANSI standard C compiler.
CC=cc

# Library (archive) tool used to combine groups of object files into
# a single file.
AR=ar

# Arguments to be passed to the C compiler.
#
# Below are compiler flags which may be of use if you are porting NEdit to a
# new system:
#
# DONT_HAVE_GLOB    Some older systems don't have the glob subroutine for
# USE_MOTIF_GLOB    expanding file names.  If the linker complains about not
#		    finding "glob" and "globfree", first try adding:
#		    -DUSE_MOTIF_GLOB, which will use a private Motif routine
#		    in place of "glob".  Being a private routine, it is not
#		    available in all Motif implementations, and you may have
#		    to resort to -DDONT_HAVE_GLOB, and NEdit will not be able
#		    to expand wildcards in the "Open Selected" command (which
#		    is no huge loss).
#
# USE_DIRENT	    Some Unix systems call the structure used by the readdir
#   	    	    subroutine dirent, rather than direct.  Add -DUSE_DIRENT
#		    to CFLAGS if your C compiler complains about the line:
#
#		       struct direct *DirEntryPtr;
#
# USE_LPR_PRINT_CMD NEdit considers the standard Unix print command to be "lp"
#   	    	    unless told otherwise.  If the standard command on your
#		    system type is "lpr", define this.  (This is just the last
#		    resort default.  You can redefine the print command to be
#		    whatever you like via X resource settings).
#
# DONT_USE_ACCESS   NEdit used to determine the accessibility of a file by
#		    trying to open it.  However, one of the more popular
#		    commercial configuration management tools, ClearCase,
#		    considers opening a file in read/write mode to be a
#		    modification, even if no writing is ever done.  This lead
#		    to users having trouble with ClearCase thinking their
#		    files had been modified when they hadn't.  NEdit now uses
#		    access() to determine whether a file is writable (in a
#		    safe way).  The old behavior can be restored by defining
#		    DONT_USE_ACCESS.
#
# ROWCOLPATCH	    Patches around a problem in several versions the Solaris
#   	    	    Motif library which can cause crashes when a wiget is
#		    destroyed.  See comments in window.c for details.
#
# IBM_FWRITE_BUG    Killer AIX system bug with fwrite system call.  Only
#   	    	    affects one release of AIX, but can cause data corruption.
#		    IBM actually denies that this bug ever existed, but it
#		    was pretty widespread.
#
# EDITRES   	    If you have the Xmu library, define this to give NEdit
#   	    	    the capability of being probed by editres to display its
#		    widget tree.  Editres is useful in customizing details
#		    of X applications which their developers have deemed too
#		    minute to document.  If you define this, you must also add
#		    -lXmu to LIBS
#
# NO_XMIM	    Don't use the Motif version of the international character
# 		    set input routines in the nedit text widget.  Turn this on
#		    if you see crashes in routines beginning with XmIm.  Such
#		    bugs exist in IRIX 6.5 and some older Motif versions.
#
# REPLACE_SCOPE     Currently, two alternative (but functionally equivalent)
#                   Replace/Find dialog box layouts are available. By default,
#                   a layout with 2 rows of push buttons is built. Compiling 
#                   with the REPLACE_SCOPE flag enables an alternative layout 
#                   with a row of radio buttons for selecting the scope of the 
#                   replace operations. Eventually, one of these alternatives 
#                   will probably disappear. Please let us know which one you
#                   prefer (via the discuss mailing list, for instance).
#
# HAVE__XMVERSIONSTRING If the Motif library exports the runtime version this
#                   will display both strings in the version info to help
#                   confirm the compile time and run time versions are
#                   compatible.
#
# NO_READLINK       Define if your system doesn't have the UNIX interface
#                   readlink(2) - or just no symlinks at all.
#
# HAVE_CONFIG_H     Include config.h from toplevel directory in front
#                   of all other headers in each .c source file.
#                   Only useful for developers so far.
#
# HAVE_DEBUG_H      Include debug.h from toplevel directory after
#                   all other headers in each .c source file.
#                   Only useful for developers.
#
# Some compilers need to be told to operate in ansi-standard mode, some have
# different levels of optimization that you can select (optimization improves
# syntax highlighting performance.   You will also often need to add locations
# of X and/or Motif include files if they are not in the compiler's standard

"Text filling using the Fill Paragraph command in the Edit menu is one of the ",
"most important concepts in NEdit.  And it will be well worth your while to ",
"understand how to use it properly. ",
"\n\n",
"In plain text files, unlike word-processor files, there is no way to tell ",
"which lines are continuations of other lines, and which lines are meant to be ",
"separate, because there is no distinction in meaning between newline ",
"characters which separate lines in a paragraph, and ones which separate ",
"paragraphs from other text.  This makes it impossible for a text editor like ",
"NEdit to tell parts of the text which belong together as a paragraph from ",
"carefully arranged individual lines. ",
"\n\n",
"In continuous wrap mode (Preferences -> Wrap -> Continuous), lines ",
"automatically wrap and unwrap themselves to line up properly at the right ",
"margin.  In this mode, you simply omit the newlines within paragraphs and let ",
"NEdit make the line breaks as needed.  Unfortunately, continuous wrap mode is ",
"not appropriate in the majority of situations, because files with extremely ",
"long lines are not common under Unix and may not be compatible with all ",
"tools, and because you can't achieve effects like indented sections, columns, ",
"or program comments, and still take advantage of the automatic wrapping. ",
"\n\n",
"Without continuous wrapping, paragraph filling is not entirely automatic. ",
"Auto-Newline wrapping keeps paragraphs lined up as you type, but once ",
"entered, NEdit can no longer distinguish newlines which join wrapped text, ",
"and newlines which must be preserved.  Therefore, editing in the middle of a ",
"paragraph will often leave the right margin messy and uneven. ",
"\n\n",
"Since NEdit can't act automatically to keep your text lined up, you need to ",
"tell it explicitly where to operate, and that is what Fill Paragraph is for. ",
"It arranges lines to fill the space between two margins, wrapping the lines ",
"neatly at word boundaries.  Normally, the left margin for filling is inferred ",
"from the text being filled.  The first line of each paragraph is considered ",
"special, and its left indentation is maintained separately from the remaining ",
"lines (for leading indents, bullet points, numbered paragraphs, etc.). ",
"Otherwise, the left margin is determined by the furthest left non-whitespace ",
"character.  The right margin is either the Wrap Margin, set in the ",
"preferences menu (by default, the right edge of the window), or can also be ",
"chosen on the fly by using a rectangular selection (see below). ",
"\n\n",
"There are three ways to use Fill Paragraph.  The simplest is, while you are ",
"typing text, and there is no selection, simply select Fill Paragraph (or type ",
"Ctrl+J), and NEdit will arrange the text in the paragraph adjacent to the ",
"cursor.  A paragraph, in this case, means an area of text delimited by blank ",
"lines. ",
"\n\n",
"The second way to use Fill Paragraph is with a selection.  If you select a ",
"range of text and then chose Fill Paragraph, all of the text in the selection ",
"will be filled.  Again, continuous text between blank lines is interpreted as ",
"paragraphs and filled individually, respecting leading indents and blank ",
"lines. ",
"\n\n",
"The third, and most versatile, way to use Fill Paragraph is with a ",
"rectangular selection.  Fill Paragraph treats rectangular selections ",
"differently from other commands.  Instead of simply filling the text inside ",
"the rectangular selection, NEdit interprets the right edge of the selection ",
"as the requested wrap margin.  Text to the left of the selection is not ",
"disturbed (the usual interpretation of a rectangular selection), but text to ",
"the right of the selection is included in the operation and is pulled in to ",
"the selected region.  This method enables you to fill text to an arbitrary ",
"right margin, without going back and forth to the wrap-margin dialog, as well ",

"A regex is a specification of a pattern to be matched in the searched text. ",
"This pattern consists of a sequence of tokens, each being able to match a ",

"specific position within the text has been reached (the latter is called an ",
"anchor.)  Tokens (also called atoms) can be modified by adding one of a number ",

"section below.) ",
"\n\n",
"\01RThe 'Any' Character\01I",
"\n\n",
"If a dot (`.') appears in a regex, it means to match any character exactly ",
"once.  By default, dot will not match a newline character, but this behavior ",

"heading, Matching Newlines). ",

"\01RCharacter Classes\01I",

"\01A     [...]   Regular class, match only characters listed.\n",
"     [^...]  Negated class, match only characters NOT listed.\n",
"\01I\n",
"As with the dot token, by default negated character classes do not match ",
"newline, but can be made to do so. ",

"The characters that are considered special within a class specification are ",
"different than the rest of regex syntax as follows. If the first character in ",
"a class is the `]' character (second character if the first character is `^') ",
"it is a literal character and part of the class character set.  This also ",
"applies if the first or last character is `-'.  Outside of these rules, two ",
"characters separated by `-' form a character range which includes all the ",
"characters between the two characters as well.  For example, `[^f-j]' is the ",
"same as `[^fghij]' and means to match any character that is not `f', `g', ",
"`h', `i', or `j'. ",
"\n\n",
"\01RAnchors\01I",

"Anchors are assertions that you are at a very specific position within the ",

"\01A     ^    Beginning of line\n",
"     $    End of line\n",
"     <    Left word boundary\n",
"     >    Right word boundary\n",
"     \\B   Not a word boundary\n",
"\01I\n",
"Note that the \\B token ensures that neither the left nor the right ",
"character are delimiters, or that both left and right characters are ",
"delimiters.  The left word anchor checks whether the previous character ",
"is a delimiter and the next character is not.  The right word anchor ",
"works in a similar way. ",
"\n\n",
"\01RQuantifiers\01I",
"\n\n",
"Quantifiers specify how many times the previous regular expression atom may ",
"be matched in the search text.  Some quantifiers can produce a large ",
"performance penalty, and can in some instances completely lock up NEdit.  To ",
"prevent this, avoid nested quantifiers, especially those of the maximal ",
"matching type (see below.) ",
"\n\n",

"\01A     {min,max}  Match from `min' to `max' times the\n",
"                previous regular expression atom.\n",
"\01I\n",
"If `min' is omitted, it is assumed to be zero.  If `max' is omitted, it is ",
"assumed to be infinity.  Whether specified or assumed, `min' must be less ",
"than or equal to `max'.  Note that both `min' and `max' are limited to ",
"65535.  If both are omitted, then the construct is the same as `*'.   Note ",
"that `{,}' and `{}' are both valid brace constructs.  A single number ",
"appearing without a comma, e.g. `{3}' is short for the `{min,min}' construct, ",
"or to match exactly `min' number of times. ",
"\n\n",
"The quantifiers `{1}' and `{1,1}' are accepted by the syntax, but are ",
"optimized away since they mean to match exactly once, which is redundant ",
"information.  Also, for efficiency, certain combinations of `min' and `max' ",
"are converted to either `*', `+', or `?' as follows: ",
"\n\n",
"\01A     {} {,} {0,}    *\n",
"     {1,}           +\n",
"     {,1} {0,1}     ?\n",
"\01I\n",
"Note that {0} and {0,0} are meaningless and will generate an error message at ",
"regular expression compile time. ",
"\n\n",
"Brace quantifiers can also be \"lazy\".  For example {2,5}? would try to match ",
"2 times if possible, and will only match 3, 4, or 5 times if that is what is ",
"necessary to achieve an overall match. ",
"\n\n",
"\01RAlternation\01I",
"\n\n",
"A series of alternative patterns to match can be specified by separating them ",
"with vertical pipes, `|'.  An example of alternation would be `a|be|sea'. ",

"this guarantees that the expression will match. ",

"example, \\0777 will be interpreted as \\077 (a `?' character) followed by `7' ",
"since \\0777 is greater than \\0377. ",
"\n\n",
"An invalid digit will also end an octal or hexadecimal escape.  For example, ",

"Blank lines and comments are also allowed.  Comments begin with a \"#\" and end ",

"of a statement. ",
"\n\n",
"Statements which are too long to fit on a single line may be split across ",

"to be continued. ",
"\n\n",
"\01RData Types\01I",
"\n\n",
"The NEdit macro language recognizes only three data types, dynamic character ",
"strings, integer values and associative arrays. In general strings and ",
"integers can be used interchangeably. If a string represents an integer ",
"value, it can be used as an integer. Integers can be compared and ",
"concatenated with strings. Arrays may contain integers, strings, or arrays. ",
"Arrays are stored key/value pairs. Keys are always stored as strings. ",
"\n\n",
"\01SInteger Constants\01I",
"\n\n",
"Integers are non-fractional numbers in the range of -2147483647 to ",
"2147483647.  Integer constants must be in decimal.  For example: ",
"\n\n",
"\01A    a = -1\n",
"    b = 1000\n",
"\01I\n",
"\01SCharacter String Constants\01I",
"\n\n",
"Character string constants are enclosed in double quotes.  For example: ",
"\n\n",
"\01A     a = \"a string\"\n",
"     dialog(\"Hi there!\", \"OK\")\n",
"\01I\n",
"Strings may also include C-language style escape sequences: ",
"\n\n",
"\01A     \\\\ Backslash     \\t Tab              \\f Form feed\n",
"     \\\" Double quote  \\b Backspace        \\a Alert\n",
"     \\n Newline       \\r Carriage return  \\v Vertical tab\n",
"\01I\n",
"Also allowed is the escape control character sequence: ",
"\n\n",
"\01A     \\e Escape (ASCII or EBCDIC,\n",
"                depending on NEdit compilation settings)\n",
"\01I\n",
"For example, to send output to the terminal from which NEdit was started, a ",
"newline character is necessary because, like printf, t_print requires ",
"explicit newlines, and also buffers its output on a per-line basis: ",
"\n\n",
"\01A     t_print(\"a = \" a \"\\n\")\n",
"\01I\n",
"Other characters can be expressed as backslash-escape sequences in macro ",
"strings. The format is the same as for regular expressions, described in the ",
"paragraphs headed \"Octal and Hex Escape Sequences\" of the section ",
"\"\01QMetacharacters\01I\", except that an octal escape sequence can start with any ",
"octal digit, not just 0, so the single character string \"\\0033\" is the same ",
"as \"\\33\", \"\\x1B\" and \"\\e\" (for an ASCII version of NEdit). ",
"\n\n",
"Note that if you want to define a regular expression in a macro string, ",
"you need to \"double-up\" the backslashes for the metacharacters with ",
"special meaning in regular expressions. For example, the expression ",
"\n\n",
"\01A     (?N(\\s|/\\*(?n(?:(?!\\*/).)*)\\*/|//.*\\n|\\n)+)\n",
"\01I\n",
"which matches whitespace or C/C++/Java-style comments, should be written as ",

"\n\n",
"\01A     \"(?N(\\\\s|/\\\\*(?n(?:(?!\\\\*/).)*)\\\\*/|//.*\\n|\\n)+)\"\n",
"\01I\n",
"(The \"\\n\"s towards the end add literal newline characters to the string. The ",
"regular expression interpretation treats the newlines as themselves. It can ",
"also interpret the sequence \"\\\\n\" as a newline, although the macro string here ",
"would then contain a literal backslash followed by a lowercase `N'.) ",
"\n\n",

"setting them (no explicit declarations are necessary). ",
"\n\n",
"Local variables are limited in scope to the subroutine (or menu item ",

"\n\n",
"\01SBuilt-in Variables\01I",
"\n\n",
"NEdit has a number of permanently defined variables, which are used to access ",

"the section titled \"\01QMacro Subroutines\01I\". ",
"\n\n",
"\01RFunctions and Subroutines\01I",
"\n\n",
"The syntax of a function or subroutine call is: ",
"\n\n",
"\01A     function_name(arg1, arg2, ...)\n",
"\01I\n",
"where arg1, arg2, etc. represent the argument values which are passed to ",
"the routine being called.  A function or subroutine call can be on a line by ",
"itself, as above, or if it returns a value, can be invoked within a character ",
"or numeric expression: ",
"\n\n",
"\01A     a = fn1(b, c) + fn2(d)\n",
"     dialog(\"fn3 says: \" fn3())\n",
"\01I\n",
"Arguments are passed by value.  This means that you can not return values via ",
"the argument list, only through the function value or indirectly through ",
"agreed-upon global variables. ",
"\n\n",
"\01SBuilt-in Functions\01I",
"\n\n",
"NEdit has a wide range of built in functions which can be called from the ",
"macro language.  These routines are divided into two classes, macro-language ",
"functions, and editor action routines.  Editor action routines are more ",
"flexible, in that they may be called either from the macro language, or bound ",
"directly to keys via translation tables.  They are also limited, however, in ",
"that they can not return values.  Macro language routines can return values, ",
"but can not be bound to keys in translation tables. ",
"\n\n",
"Nearly all of the built-in subroutines operate on an implied window, which is ",
"initially the window from which the macro was started.  To manipulate the ",
"contents of other windows, use the focus_window subroutine to change the ",
"focus to the ones you wish to modify.  focus_window can also be used to ",
"iterate over all of the currently open windows, using the special keyword ",
"names, \"last\" and \"next\". ",
"\n\n",
"For backwards compatibility, hyphenated action routine names are allowed, and ",
"most of the existing action routines names which contain underscores have an ",
"equivalent version containing hyphens ('-') instead of underscores.  Use of ",
"these names is discouraged.  The macro parser resolves the ambiguity between ",
"'-' as the subtraction/negation operator, and - as part of an action routine ",
"name by assuming subtraction unless the symbol specifically matches an action ",
"routine name. ",

"\n\n",
"The arguments with which a user-defined subroutine or function was invoked, ",

"to an integer from 1 to the number of arguments.  The number of arguments can ",
"be read from $n_args or $args[]. The array $args[expr] is the only way to ",
"access arguments beyond the first 9. ",

"\n\n",
"\01SArrays and Array Operators\01I",
"\n\n",
"Arrays may contain either strings, integers, or other arrays. Arrays are ",
"associative, which means that they relate two pieces of information, the key ",
"and  the value. The key is always a string; if you use an integer it is ",
"converted to a string. ",
"\n\n",
"To determine if a given key is in an array, use the 'in' keyword. ",
"\n\n",
"\01A      if (\"6\" in x)\n",
"          \n",
"\01I\n",
"If the left side of the in keyword is an array, the result is true if every ",
"key in the left array is in the right array. Array values are not compared. ",
"\n\n",
"To iterate through all the keys of an array use the 'for' looping construct. ",
"Keys are not guaranteed in any particular order: ",
"\n\n",
"\01A      for (aKey in x)\n",
"          \n",
"\01I\n",
"Elements can be removed from an array using the delete command: ",
"\n\n",
"\01A      delete x[3] # deletes element with key 3\n",
"      delete x[]  # deletes all elements\n",
"\01I\n",

"array with no indices: ",
"\n\n",
"\01A      dialog(\"array x has \" x[] \" elements\", \"OK\")\n",
"\01I\n",
"Arrays can be combined with some operators. All the following operators only ",
"compare the keys of the arrays. ",
"\n\n",
"\01A      result = x + y   (Merge arrays)\n",
"\01I\n",
"The 'result' is a new array containing keys from both x and y. If ",
"duplicates are present values from y are used. ",
"\n\n",
"\01A      result = x - y   (Remove keys)\n",
"\01I\n",
"The 'result' is a new array containing all keys from x that are not in y. ",

"When duplicate keys are encountered using the + and & operators, the values ",
"from the array on the right side of the operators are used for the result. ",
"All  of the above operators are array only, meaning both the left and right ",
"sides of the operator must be arrays. The results are also arrays. ",
"\n\n",
"Array keys can also contain multiple dimensions: ",
"\n\n",
"\01A      x[1, 1, 1] = \"string\"\n",
"\01I\n",
"These are used in the expected way, e.g.: ",
"\n\n",

"\01IA rangeset is a set of ranges. A range is a contiguous range of characters ",
"defined by its start and end position in the document.  The user can ",
"create rangesets, identified by arbitrary integers (chosen by the editor when ",
"the rangesets are created), and each range within a rangeset is identified by ",
"a numeric index, counting from 1, in the order of appearance in the text ",
"buffer.  The ranges are adjusted when modifications are made to the text ",
"buffer: they shuffle around when characters are added or deleted.  However, ",
"ranges within a set will coalesce if the characters between them are removed, ",
"or a new range is added to the set which bridges or overlaps others. ",
"\n\n",
"Using rangesets allows non-contiguous bits of the text to be identified as a ",
"group. ",
"\n\n",
"Rangesets can be assigned a background color: characters within a range of a ",
"rangeset will have the background color of the rangeset. If more than one ",
"rangeset includes a given character, its background color will be that of the ",
"most recently created rangeset which has a color defined. ",
"\n\n",
"Rangesets must be created using the rangeset_create() function, which ",
"will return an identifier for the newly-created rangeset.  This identifier ",
"is then passed to the other rangeset functions to manipulate the rangeset. ",
"\n\n",
"There is a limit to the number of rangesets which can exist at any time - ",
"currently up to 63 in each document.  Care should be taken to destroy ",
"any rangesets which are no longer needed, by using the rangeset_destroy() ",
"function, if this limit is attained. ",
"\n\n",
"Rangesets can be named: this is useful for macros which need a fixed ",
"identification for rangesets which are used for the same purpose in ",
"different documents.  Although a new rangeset's number is arbitrary, its ",
"name can be fixed.  This is done using the rangeset_set_name() function. ",
"Note that rangeset names within a particular document may not be unique. ",

"\n\n",
"\01SHow rangesets change with modifications\01I",
"\n\n",
"When changes are made to the document text, ranges within each set are altered ",
"with it, according to their behavioral mode.  If changes are made outside of ",
"the ranges in a rangeset, each range simply maintains its size and adjusts its ",
"position to match the changes.  When text within a range is deleted, the ",
"range's length is reduced by the same amount. When changes involving new text ",
"are made within a range of the set, or to one of the extremities of a range, ",
"different behaviours may be desirable. The rangeset_set_mode() function allows ",
"these modes to be chosen. ",
"\n\n",
"Note that the precise behaviour of these modes may change in future versions ",
"of NEdit. ",
"\n\n",
"The available modes are: ",
"\n\n",
"\01Jmaintain\01I or \01Jins_del\01I - ",
"Both these modes have the same behaviour.  New text added at the front of a ",
"range in a set is not added to the range; new text added within the range or ",
"at the end extends the range.  Replacement overlapping an extremity of the ",
"set acts as if the new text were added first, then the old text deleted. ",
"This causes curtailment at the front of the range, extension at the end. ",
"Replacement of the full text of the range removes the range from the set. ",
"The default behaviour for a newly created rangeset is \01Jmaintain\01I. ",
"\n\n",
"\01Jdel_ins\01I - ",
"New text added at the front or end of a range in a set is not added to the ",
"range; new text added within the range extends the range.  Replacement ",
"overlapping an extremity of the set acts as if the old text were deleted ",
"first, then the new text added. This causes curtailment at either end. ",
"Replacement of the full text of the range removes the range from the set. ",
"\n\n",
"\01Jinclude\01I - ",
"New text added at the front or end of a range in a set extends the range, as ",
"does new text added within the range.  Replacement overlapping an extremity ",
"of the set acts as if the new text were added first, then the old text ",
"deleted.  This causes curtailment at the front of the range, extension at ",
"the end.  Replacement of the full text of the range adds the new text to the ",
"range if the start position of the replacement is at the range's start ",
"point. ",
"\n\n",
"\01Jexclude\01I - ",
"New text added at the front or end of a range in a set does not extend the ",

"\n\n",
"The font used to display text in NEdit is set under Preferences -> Text Font ",
"(for the current window), or Preferences -> Default Settings Text Font (for ",
"future windows).  These dialogs also allow you to set fonts for syntax ",
"highlighting.  If you don't intend to use syntax highlighting, you can ignore ",
"most of the dialog, and just set the field labeled Primary Font. ",
"\n\n",
"Unless you are absolutely certain about the types of files that you will be ",
"editing with NEdit, you should choose a fixed-spacing font.  Many, if not ",
"most, plain-text files are written expecting to be viewed with fixed ",
"character spacing, and will look wrong with proportional spacing.  NEdit's ",
"filling, wrapping, and rectangular operations will also work strangely if you ",
"choose a proportional font. ",
"\n\n",
"Note that in the font browser (the dialog brought up by the Browse... ",
"button), the subset of fonts which are shown is narrowed depending on the ",
"characteristics already selected.  It is therefore important to know that you ",
"can unselect characteristics from the lists by clicking on the selected items ",
"a second time. ",
"\n\n",
"Fonts for syntax highlighting should ideally match the primary font in both ",
"height and spacing.  A mismatch in spacing will result in similar distortions ",
"as choosing a proportional font: column alignment will sometimes look wrong, ",
"and rectangular operations, wrapping, and filling will behave strangely.  A ",
"mismatch in height will cause windows to re-size themselves slightly when ",

"which match exactly in height. ",

"\01RCustomizing Menus\01I",
"\n\n",
"You can add or change items in the Shell, Macro, and window background menus ",
"under Preferences -> Default Settings -> Customize Menus.  When you choose ",
"one of these, you will see a dialog with a list of the current ",
"user-configurable items from the menu on the left.  To change an existing ",
"item, select it from the list, and its properties will appear in the ",
"remaining fields of the dialog, where you may change them.  Selecting the ",
"item \"New\" from the list allows you to enter new items in the menu. ",
"\n\n",
"Hopefully most of the characteristics are self explanatory, but here are a ",
"few things to note: ",
"\n\n",
"Accelerator keys are keyboard shortcuts which appear on the right hand side ",
"of the menus, and allow you avoid pulling down the menu and activate the ",
"command with a single keystroke.  Enter accelerators by typing the keys ",
"exactly as you would to activate the command. ",
"\n\n",
"Mnemonics are a single letter which should be part of the menu item name, ",
"which allow users to traverse and activate menu items by typing keys when the ",
"menu is pulled down. ",
"\n\n",
"In the Shell Command field of the Shell Commands dialog, the % character ",
"expands to the name (including directory path) of the file in the window.  To ",
"include a % character in the command, use %%. ",
"\n\n",
"The Menu Entry field can contain special characters for constructing ",
"hierarchical sub-menus, and for making items which appear only in certain ",
"language modes.  The right angle bracket character \">\" creates a sub-menu. ",
"The name of the item itself should be the last element of the path formed ",
"from successive sub-menu names joined with \">\".  Menu panes are called in to ",
"existence simply by naming them as part of a Menu Entry name.  To put several ",
"items in the same sub-menu, repeat the same hierarchical sequence for each. ",
"For example, in the Macro Commands dialog, two items with menu entries: a>b>c ",
"and a>b>d would create a single sub menu under the macro menu called \"a\", ",
"which would contain a single sub-menu, b, holding the actual items, c and d: ",
"\n\n",
"\01A      +---++---++---+\n",
"      |a >||b >||c  |\n",
"      +---++---+|d  |\n",
"                +---+\n",
"\01I\n",
"To qualify a menu entry with a language mode, simply add an at-sign \"@\" at ",
"the end of the menu command, followed (no space) by a language mode name.  To ",
"make a menu item which appears in several language modes, append additional ",
"@s and language mode names.  For example, an item with the menu entry: ",
"\n\n",
"\01A    Make C Prototypes@C@C++\n",
"\01I\n",
"would appear only in C and C++ language modes, and: ",
"\n\n",
"\01A    Make Class Template@C++\n",
"\01I\n",
"would appear only in C++ mode. ",
"\n\n",
"Menu items with no qualification appear in all language modes. ",
"\n\n",
"If a menu item is followed by the single language qualification \"@*\", that ",
"item will appear only if there are no applicable language-specific items of ",
"the same name in the same submenu.  For example, if you have the following ",
"three entries in the same menu: ",
"\n\n",
"\01A    Make Prototypes@C@C++\n",
"    Make Prototypes@Java\n",
"    Make Prototypes@*\n",
"\01I\n",
"The first will be available when the language mode is C or C++, the second ",
"when the language mode is Java, and for all other language modes (including ",
"the \"Plain\" non-language mode).  If the entry: ",
"\n\n",
"\01A    Make Prototypes\n",
"\01I\n",
"also exists, this will always appear, meaning that the menu will always have ",
"two \"Make Prototypes\" entries, whatever the language mode. ",
"\n\n",
"\01RThe NEdit Autoload Files\01I",
"\n\n",
"At startup time, NEdit automatically reads the preferences file ",
"`nedit.rc', the autoload macro file `autoload.nm', and the history data base ",
"`nedit.history'.  The preferences file contains saved preferences (menu ",
"settings) in the format of an X resource file.  The autoload macro file is a ",
"macro file containing macro commands and definitions that NEdit will ",
"execute at startup.  (NEdit doesn't create this file automatically.) ",
"Moreover, NEdit saves a list of the recently opened files, which appear under ",
"the Open Previous menu, in the history data base. ",
"\n\n",
"By default the location of these files is '$HOME/.nedit/'.  A different ",
"directory can be given by letting the environment variable NEDIT_HOME ",
"point to it. ",
"\n\n",
"Notice that NEdit still supports the older names for these files, which are ",
"`$HOME/.nedit', `$HOME/.neditmacro', and `$HOME/.neditdb', respectively. This ",
"old naming scheme will be used if NEdit detects that `$HOME/.nedit' is a ",
"regular file and NEDIT_HOME isn't set. ",
"\n\n",
"(For VMS, the location of these files is '$NEDIT_HOME/' if NEDIT_HOME is set, ",
"and 'SYS$LOGIN:' otherwise.) ",
"\n\n",
"The contents of the preferences file can be moved into another X resource ",
"file (see \01QX Resources\01I).  One reason for doing so would be to attach server ",
"specific preferences, such as a default font, to a particular X server. ",
"Another reason for moving preferences into an X resource file would be to ",
"keep preferences menu options and X resource settable options together in ",
"one place.  Though the files are the same format, additional resources ",
"should not be added to the preferences file, since NEdit modifies that file ",
"by overwriting it completely.  Note also that the contents of the ",
"preferences file takes precedence over the values in an X resource file. ",
"Using Save Defaults after moving the contents of your preferences file to ",
"your .Xdefaults file will re-create the preferences file, interfering with ",
"the options that you have moved. ",
"\n\n",
"\01RSharing Customizations with Other NEdit Users\01I",
"\n\n",
"If you have written macro or shell menu commands, highlight patterns, or ",
"smart-indent macros that you want to share with other NEdit users, you can ",
"make a file which they can load into their NEdit environment. ",
"\n\n",
"To load such a file, start NEdit with the command: ",
"\n\n",
"\01A     nedit -import \n",
"\01I\n",
"In the new NEdit session, verify that the imported patterns or macros do what ",
"you want, then select Preferences -> Save Defaults.  Saving incorporates the ",
"changes into the NEdit preferences file, so the next time you run NEdit, you ",
"will not have to import the distribution file. ",
"\n\n",
"Loading a customization file is automated, but creating one is not.  To ",
"produce a file to be imported by other users, you must make a copy of your own ",
"preferences file, and edit it, by hand, to remove everything but the ",
"few items of interest to the recipient.  Leave only the individual ",
"resource(s), and within those resources, only the particular macro, pattern, ",
"style, etc, that you wish to exchange. ",
"\n\n",
"For example, to share a highlighting pattern set, you would include the ",
"patterns, any new styles you added, and language mode information only if the ",
"patterns are intended to support a new language rather than updating an ",
"existing one. For example: ",
"\n\n",
"\01A     nedit.highlightPatterns:\\\n",
"          My Language:1:0{\\n\\\n",

"Resources are in the format of X resource files, but the format of text ",
"within multiple-item resources like highlight patterns, language modes, ",

"ends at the first newline character not escaped with \\, so you must be ",
"careful about how you treat ends of lines.  While you can generally just cut ",

"of a resource string is now at the end, you must remove the \\ line ",
"continuation character(s) so it will not join the next line into the ",
"resource.  Conversely, if something which was originally at the end of a ",
"resource is now in the middle, you'll have to add continuation character(s) ",
"to make sure that the resource string is properly continued from beginning to ",

"need to do so via X resources. ",
"\n\n",
"Before reading this section, you must understand how to set X resources (see ",

"\n\n",
"\01RKey Binding in General\01I",
"\n\n",
"Keyboard commands are associated with editor action routines through two ",

"called an accelerator key.  Commands which do not have an associated menu ",
"item are bound to keys via the X toolkit translation mechanism.  The methods ",
"for changing these two kinds of bindings are quite different. ",
"\n\n",
"\01RKey Binding Via Translations\01I",
"\n\n",
"The most general way to bind actions to keys in NEdit is to use the ",
"translation table associated with the text widget.  To add a binding to Alt+Y ",
"to insert the string \"Hi!\", for example, add lines similar to the following ",
"to your X resource file: ",
"\n\n",
"\01A    NEdit*text.Translations: #override \\n\\\n",
"      Alty: insert_string(\"Hi!\") \\n\n",
"\01I\n",
"The Help topic \"\01QAction Routines\01I\" lists the actions available to be bound. ",
"\n\n",
"Translation tables map key and mouse presses, window operations, and other ",
"kinds of events, to actions. The syntax for translation tables is ",
"simplified here, so you may need to refer to a book on the X window system ",
"for more detailed information. ",
"\n\n",
"Note that accelerator resources (discussed below) override translations, and ",
"that most Ctrl+letter and Alt+letter combinations are already bound to an ",
"accelerator key.  To use one of these combinations from a translation table, ",
"therefore, you must first un-bind the original menu accelerator. ",
"\n\n",
"A resource for changing a translation table consists of a keyword; #override, ",
"#augment, or #replace; followed by lines (separated by newline characters) ",
"pairing events with actions.  Events begin with modifiers, like Ctrl, Shift, ",
"or Alt, followed by the event type in <>.  BtnDown, Btn1Down, Btn2Down, ",
"Btn1Up, Key, KeyUp are valid event types.  For key presses, the event type is ",
"followed by the name of the key.  You can specify a combination of events, ",
"such as a sequence of key presses, by separating them with commas.  The other ",
"half of the event/action pair is a set of actions.  These are separated from ",
"the event specification by a colon and from each other by spaces.  Actions ",

"string shown in the menu.  The form of the accelerator resource is the same ",
"as events for translation table entries discussed above, though multiple keys ",
"and other subtleties are not allowed.  The resource name for a menu is the ",

static char * htxt_patterns [] = {
"\01RWriting Syntax Highlighting Patterns\01I",
"\n\n",
"Patterns are the mechanism by which language syntax highlighting is ",
"implemented in NEdit (see \01QSyntax Highlighting\01I under the heading of Features ",
"for Programming). To create syntax highlighting patterns for a new ",
"language, or to modify existing patterns, select \"Recognition Patterns\" from ",
"\"Syntax Highlighting\" sub-section of the \"Default Settings\" sub-menu of the ",
"\"Preferences\" menu. ",
"\n\n",
"First, a word of caution.  As with regular expression matching in general, it ",
"is quite possible to write patterns which are so inefficient that they ",
"essentially lock up the editor as they recursively re-examine the entire ",
"contents of the file thousands of times.  With the multiplicity of patterns, ",
"the possibility of a lock-up is significantly increased in syntax ",
"highlighting.  When working on highlighting patterns, be sure to save your ",
"work frequently. ",
"\n\n",
"NEdit's syntax highlighting is unusual in that it works in real-time (as you ",
"type), and yet is completely programmable using standard regular expression ",
"notation.  Other syntax highlighting editors usually fall either into the ",
"category of fully programmable but unable to keep up in real-time, or ",
"real-time but limited programmability.  The additional burden that NEdit ",
"places on pattern writers in order to achieve this speed/flexibility mix, is ",
"to force them to state self-imposed limitations on the amount of context that ",
"patterns may examine when re-parsing after a change.  While the \"Pattern ",
"Context Requirements\" heading is near the end of this section, it is not ",
"optional, and must be understood before making any serious effort at ",
"pattern writing. ",
"\n\n",
"In its simplest form, a highlight pattern consists of a regular expression to ",
"match, along with a style representing the font an color for displaying any ",
"text which matches that expression.  To bold the word, \"highlight\", wherever ",
"it appears the text, the regular expression simply would be the word ",
"\"highlight\".  The style (selected from the menu under the heading of ",
"\"Highlight Style\") determines how the text will be drawn.  To bold the text, ",
"either select an existing style, such as \"Keyword\", which bolds text, or ",
"create a new style and select it under Highlight Style. ",
"\n\n",
"The full range of regular expression capabilities can be applied in such a ",
"pattern, with the single caveat that the expression must conclusively match ",
"or not match, within the pre-defined context distance (as discussed below ",
"under Pattern Context Requirements). ",
"\n\n",
"To match longer ranges of text, particularly any constructs which exceed the ",
"requested context, you must use a pattern which highlights text between a ",
"starting and ending regular expression match.  To do so, select \"Highlight ",
"text between starting and ending REs\" under \"Matching\", and enter both a ",
"starting and ending regular expression.  For example, to highlight everything ",
"between double quotes, you would enter a double quote character in both the ",
"starting and ending regular expression fields.  Patterns with both a ",
"beginning and ending expression span all characters between the two ",
"expressions, including newlines. ",
"\n\n",
"Again, the limitation for automatic parsing to operate properly is that both ",
"expressions must match within the context distance stated for the pattern ",
"set. ",
"\n\n",
"With the ability to span large distances, comes the responsibility to recover ",
"when things go wrong.  Remember that syntax highlighting is called upon to ",
"parse incorrect or incomplete syntax as often as correct syntax.  To stop a ",
"pattern short of matching its end expression, you can specify an error ",
"expression, which stops the pattern from gobbling up more than it should. ",
"For example, if the text between double quotes shouldn't contain newlines, ",
"the error expression might be \"$\".  As with both starting and ending ",
"expressions, error expressions must also match within the requested context ",
"distance. ",
"\n\n",
"\01SColoring Sub-Expressions\01I",
"\n\n",
"It is also possible to color areas of text within a regular expression ",
"match.  A pattern of this type associates a style with sub-expressions ",
"references of the parent pattern (as used in regular expression substitution ",
"patterns, see the NEdit Help menu item on Regular Expressions). ",
"Sub-expressions of both the starting and ending patterns may be colored.  For ",
"example, if the parent pattern has a starting expression \"\\<\", and end ",
"expression \"\\>\", (for highlighting all of the text contained within angle ",
"brackets), a sub-pattern using \"&\" in both the starting and ending expression ",
"fields could color the brackets differently from the intervening text.  A ",
"quick shortcut to typing in pattern names in the Parent Pattern field is to ",
"use the middle mouse button to drag them from the Patterns list. ",
"\n\n",
"In some cases, there can be interference between coloring sub-patterns and ",
"hierarchical sub-patterns (discussed next). How this is resolved, is ",
"explained below. ",
"\n\n",
"\01SHierarchical Patterns\01I",
"\n\n",
"A hierarchical sub-pattern, is identical to a top level pattern, but is ",
"invoked only between the starting and ending expression matches of its ",
"parent pattern or, in case the parent pattern consists of a single ",
"expression, inside the text area matching that expression.  Like the ",
"sub-expression coloring patterns discussed above, it is associated with a ",
"parent pattern using the Parent Pattern field in the pattern specification. ",
"Pattern names can be dragged from the pattern list with the middle mouse ",
"button to the Parent Pattern field. ",
"\n\n",
"The matching behaviour for sub-patterns is slightly different, depending on ",
"whether the parent pattern consists of a single expression or has both a ",
"starting and an ending expression. ",
"\n\n",
"In case the parent pattern consists of a single expression, and the syntax ",
"highlighting parser finds a match for that expression, sub-patterns are ",
"matched between the start and the end of the parent match.  Sub-patterns ",
"cannot extend beyond the boundaries of the parent's match nor can they ",
"affect those boundaries (the latter can happen for starting/ending parent ",
"patterns, see below). Note that sub-patterns can \01Kpeek\01I beyond the ",
"parent's matching boundaries by means of look-ahead or look-behind ",
"expressions. ",
"\n\n",
"In case the parent pattern is a starting/ending style pattern, after the ",
"start expression of the parent pattern matches, the syntax highlighting ",
"parser searches for either the parent's end pattern or a matching ",
"sub-pattern.  When a sub-pattern matches, control is not returned to the ",
"parent pattern until the entire sub-pattern has been parsed, regardless of ",
"whether the parent's end pattern appears in the text matched by the ",
"sub-pattern.  In this way, matching of the parent's ending pattern can be ",
"postponed, in contrast to the case where the parent pattern consists of a ",
"single expression. Note that, in this case, parsing of sub-patterns starts ",
"\01Jafter\01I the match of the parent pattern's starting expression, also in ",
"contrast to the single-expression case. ",
"\n\n",
"The most common use for this capability is for coloring sub-structure of ",
"language constructs (smaller patterns embedded in larger patterns). ",
"Hierarchical patterns can also simplify parsing by having sub-patterns \"hide\" ",
"special syntax from parent patterns, such as special escape sequences or ",
"internal comments. ",
"\n\n",
"There is no depth limit in nesting hierarchical sub-patterns, but beyond the ",
"third level of nesting, automatic re-parsing will sometimes have to re-parse ",
"more than the requested context distance to guarantee a correct parse (which ",
"can slow down the maximum rate at which the user can type if large sections ",
"of text are matched only by deeply nested patterns). ",
"\n\n",
"While this is obviously not a complete hierarchical language parser it is ",
"still useful in many text coloring situations.  As a pattern writer, your ",
"goal is not to completely cover the language syntax, but to generate ",
"colorings that are useful to the programmer.  Simpler patterns are usually ",
"more efficient and also more robust when applied to incorrect code. ",
"\n\n",
"Note that in case of a single-expression parent pattern, there is a ",
"potential for conflicts between coloring-only sub-patterns and hierarchical ",
"sub-patterns (which cannot happen for starting/ending type of patterns, ",
"because sub-patterns are matched \01Jbetween\01I the starting and ending pattern ",
"(not included)).  Due to the different nature of these two kinds of ",
"sub-patterns, it is technically infeasible to follow the standard matching ",
"precedence rules, where a sub-pattern has precedence over the sub-patterns ",
"following it.  Instead, coloring-only sub-patterns are always colored last, ",
"ie., they may override the coloring for overlapping sibling sub-patterns in ",
"the overlapping parts of the matches. ",
"\n\n",
"\01SDeferred (Pass-2) Parsing\01I",
"\n\n",
"NEdit does pattern matching for syntax highlighting in two passes.  The first ",
"pass is applied to the entire file when syntax highlighting is first turned ",
"on, and to new ranges of text when they are initially read or pasted in.  The ",
"second pass is applied only as needed when text is exposed (scrolled in to ",
"view). ",
"\n\n",
"If you have a particularly complex set of patterns, and parsing is beginning ",
"to add a noticeable delay to opening files or operations which change large ",
"regions of text, you can defer some of that parsing from startup time, to ",
"when it is actually needed for viewing the text.  Deferred parsing can only ",
"be used with single expression patterns, or begin/end patterns which match ",
"entirely within the requested context distance.  To defer the parsing of a ",
"pattern to when the text is exposed, click on the Pass-2 pattern type button ",
"in the highlight patterns dialog. ",
"\n\n",
"Sometimes a pattern can't be deferred, not because of context requirements, ",
"but because it must run concurrently with pass-1 (non-deferred) patterns.  If ",
"they didn't run concurrently, a pass-1 pattern might incorrectly match some ",
"of the characters which would normally be hidden inside of a sequence matched ",
"by the deferred pattern.  For example, C has character constants enclosed in ",
"single quotes.  These typically do not cross line boundaries, meaning they ",
"can be parsed entirely within the context distance of the C pattern set and ",
"should be good candidates for deferred parsing.  However, they can't be ",
"deferred because they can contain sequences of characters which can trigger ",
"pass-one patterns. Specifically, the sequence, '\\\"', contains a double quote ",
"character, which would be matched by the string pattern and interpreted as ",
"introducing a string. ",
"\n\n",
"\01SPattern Context Requirements\01I",
"\n\n",
"The context requirements of a pattern set state how much additional text ",
"around any change must be examined to guarantee that the patterns will match ",
"what they are intended to match.  Context requirements are a promise by NEdit ",
"to the pattern writer, that the regular expressions in his/her patterns will ",
"be matched against at least  lines and  ",
"characters, around any modified text.  Combining line and character ",
"requirements guarantee that both will be met. ",
"\n\n",
"Automatic re-parsing happens on EVERY KEYSTROKE, so the amount of context ",
"which must be examined is very critical to typing efficiency.  The more ",
"complicated your patterns, the more critical the context becomes.  To cover ",
"all of the keywords in a typical language, without affecting the maximum rate ",
"at which users can enter text, you may be limited to just a few lines and/or ",
"a few hundred characters of context. ",
"\n\n",
"The default context distance is 1 line, with no minimum character ",
"requirement.  There are several benefits to sticking with this default.  One ",
"is simply that it is easy to understand and to comply with.  Regular ",
"expression notation is designed around single line matching.  To span lines ",
"in a regular expression, you must explicitly mention the newline character ",
"\"\\n\", and matches which are restricted to a single line are virtually immune ",
"to lock-ups.  Also, if you can code your patterns to work within a single ",
"line of context, without an additional character-range context requirement, ",
"the parser can take advantage the fact that patterns don't cross line ",
"boundaries, and nearly double its efficiency over a one-line and 1-character ",
"context requirement.  (In a single line context, you are allowed to match ",
"newlines, but only as the first and/or last character.) ",
NULL

static char * htxt_smart_indent [] = {
"\01ISmart indent macros can be written for any language, but are usually more ",
"difficult to write than highlighting patterns.  A good place to start, of ",
"course, is to look at the existing macros for C and C++. ",
"\n\n",
"Smart indent macros for a language mode consist of standard NEdit macro ",
"language code attached to any or all of the following three activation ",
"conditions: 1) When smart indent is first turned on for a text window ",
"containing code of the language, 2) When a newline is typed and smart indent ",

"these code \"hooks\", enter it in the appropriate section in the Preferences -> ",
"Default Settings -> Auto Indent -> Program Smart Indent dialog. ",
"\n\n",
"Typically most of the code should go in the initialization section, because ",
"that is the appropriate place for subroutine definitions, and smart indent ",
"macros are complicated enough that you are not likely to want to write them ",
"as one monolithic run of code.  You may also put code in the Common/Shared ",
"Initialization section (accessible through the button in the upper left ",
"corner of the dialog).  Unfortunately, since the C/C++ macros also reside in ",
"the common/shared section, when you add code there, you run some risk of ",
"missing out on future upgrades to these macros, because your changes will ",
"override the built-in defaults. ",
"\n\n",
"The newline macro is invoked after the user types a newline, but before the ",

"sufficient. ",
"\n\n",
"The type-in macro takes two arguments.  $1 is the insert position, and $2 is ",
"the character just inserted, and does not return a value.  You can do just ",

"software is covered by the GNU Library General Public License instead.) You ",
"can apply it to your programs, too. ",
"\n\n",
"When we speak of free software, we are referring to freedom, not price. Our ",
"General Public Licenses are designed to make sure that you have the freedom ",
"to distribute copies of free software (and charge for this service if you ",
"wish), that you receive source code or can get it if you want it, that you ",
"can change the software or use pieces of it in new free programs; and that ",
"you know you can do these things. ",
"\n\n",
"To protect your rights, we need to make restrictions that forbid anyone to ",
"deny you these rights or to ask you to surrender the rights. These ",
"restrictions translate to certain responsibilities for you if you distribute ",
"copies of the software, or if you modify it. ",
"\n\n",
"For example, if you distribute copies of such a program, whether gratis or ",
"for a fee, you must give the recipients all the rights that you have. You ",
"must make sure that they, too, receive or can get the source code. And you ",
"must show them these terms so they know their rights. ",
"\n\n",
"We protect your rights with two steps: (1) copyright the software, and (2) ",
"offer you this license which gives you legal permission to copy, distribute ",

"\n\n",
"Also, for each author's protection and ours, we want to make certain that ",
"everyone understands that there is no warranty for this free software. If the ",
"software is modified by someone else and passed on, we want its recipients to ",
"know that what they have is not the original, so that any problems introduced ",
"by others will not reflect on the original authors' reputations. ",
"\n\n",
"Finally, any free program is threatened constantly by software patents. We ",
"wish to avoid the danger that redistributors of a free program will ",
"individually obtain patent licenses, in effect making the program ",
"proprietary. To prevent this, we have made it clear that any patent must be ",
"licensed for everyone's free use or not licensed at all. ",

"0. This License applies to any program or other work which contains a notice ",

"of this General Public License. The \"Program\", below, refers to any such ",
"program or work, and a \"work based on the Program\" means either the Program ",
"or any derivative work under copyright law: that is to say, a work containing ",
"the Program or a portion of it, either verbatim or with modifications and/or ",
"translated into another language. (Hereinafter, translation is included ",
"without limitation in the term \"modification\".) Each licensee is addressed as ",
"\"you\". ",
"\n\n",
"Activities other than copying, distribution and modification are not covered ",
"by this License; they are outside its scope. The act of running the Program ",
"is not restricted, and the output from the Program is covered only if its ",
"contents constitute a work based on the Program (independent of having been ",
"made by running the Program). Whether that is true depends on what the ",
"Program does. ",
"\n\n",
"1. You may copy and distribute verbatim copies of the Program's source code ",
"as you receive it, in any medium, provided that you conspicuously and ",
"appropriately publish on each copy an appropriate copyright notice and ",
"disclaimer of warranty; keep intact all the notices that refer to this ",
"License and to the absence of any warranty; and give any other recipients of ",
"the Program a copy of this License along with the Program. ",
"\n\n",
"You may charge a fee for the physical act of transferring a copy, and you may ",
"at your option offer warranty protection in exchange for a fee. ",
"\n\n",
"2. You may modify your copy or copies of the Program or any portion of it, ",
"thus forming a work based on the Program, and copy and distribute such ",
"modifications or work under the terms of Section 1 above, provided that you ",
"also meet all of these conditions: ",
"\n\n",
"a) You must cause the modified files to carry prominent notices stating ",
"that you changed the files and the date of any change. ",
"\n\n",
"b) You must cause any work that you distribute or publish, that in whole or ",
"in part contains or is derived from the Program or any part thereof, to be ",
"licensed as a whole at no charge to all third parties under the terms of ",
"this License. ",
"\n\n",
"c) If the modified program normally reads commands interactively when run, ",
"you must cause it, when started running for such interactive use in the ",
"most ordinary way, to print or display an announcement including an ",
"appropriate copyright notice and a notice that there is no warranty (or ",
"else, saying that you provide a warranty) and that users may redistribute ",
"the program under these conditions, and telling the user how to view a copy ",
"of this License. (Exception: if the Program itself is interactive but does ",
"not normally print such an announcement, your work based on the Program is ",
"not required to print an announcement.) ",
"\n\n",
"These requirements apply to the modified work as a whole. If identifiable ",
"sections of that work are not derived from the Program, and can be reasonably ",
"considered independent and separate works in themselves, then this License, ",
"and its terms, do not apply to those sections when you distribute them as ",
"separate works. But when you distribute the same sections as part of a whole ",
"which is a work based on the Program, the distribution of the whole must be ",
"on the terms of this License, whose permissions for other licensees extend to ",
"the entire whole, and thus to each and every part regardless of who wrote it. ",
"\n\n",
"Thus, it is not the intent of this section to claim rights or contest your ",
"rights to work written entirely by you; rather, the intent is to exercise the ",
"right to control the distribution of derivative or collective works based on ",
"the Program. ",
"\n\n",
"In addition, mere aggregation of another work not based on the Program with ",
"the Program (or with a work based on the Program) on a volume of a storage or ",
"distribution medium does not bring the other work under the scope of this ",
"License. ",
"\n\n",
"3. You may copy and distribute the Program (or a work based on it, under ",
"Section 2) in object code or executable form under the terms of Sections 1 ",
"and 2 above provided that you also do one of the following: ",
"\n\n",
"a) Accompany it with the complete corresponding machine-readable source ",
"code, which must be distributed under the terms of Sections 1 and 2 above ",
"on a medium customarily used for software interchange; or, ",
"\n\n",
"b) Accompany it with a written offer, valid for at least three years, to ",
"give any third party, for a charge no more than your cost of physically ",
"performing source distribution, a complete machine-readable copy of the ",
"corresponding source code, to be distributed under the terms of Sections 1 ",
"and 2 above on a medium customarily used for software interchange; or, ",
"\n\n",
"c) Accompany it with the information you received as to the offer to ",
"distribute corresponding source code. (This alternative is allowed only for ",
"noncommercial distribution and only if you received the program in object ",
"code or executable form with such an offer, in accord with Subsection b ",
"above.) ",
"\n\n",
"The source code for a work means the preferred form of the work for making ",
"modifications to it. For an executable work, complete source code means all ",
"the source code for all modules it contains, plus any associated interface ",
"definition files, plus the scripts used to control compilation and ",
"installation of the executable. However, as a special exception, the source ",
"code distributed need not include anything that is normally distributed (in ",
"either source or binary form) with the major components (compiler, kernel, ",
"and so on) of the operating system on which the executable runs, unless that ",
"component itself accompanies the executable. ",
"\n\n",
"If distribution of executable or object code is made by offering access to ",
"copy from a designated place, then offering equivalent access to copy the ",
"source code from the same place counts as distribution of the source code, ",
"even though third parties are not compelled to copy the source along with the ",
"object code. ",
"\n\n",
"4. You may not copy, modify, sublicense, or distribute the Program except as ",
"expressly provided under this License. Any attempt otherwise to copy, modify, ",
"sublicense or distribute the Program is void, and will automatically ",
"terminate your rights under this License. However, parties who have received ",
"copies, or rights, from you under this License will not have their licenses ",
"terminated so long as such parties remain in full compliance. ",
"\n\n",
"5. You are not required to accept this License, since you have not signed it. ",
"However, nothing else grants you permission to modify or distribute the ",
"Program or its derivative works. These actions are prohibited by law if you ",
"do not accept this License. Therefore, by modifying or distributing the ",
"Program (or any work based on the Program), you indicate your acceptance of ",
"this License to do so, and all its terms and conditions for copying, ",
"distributing or modifying the Program or works based on it. ",
"\n\n",
"6. Each time you redistribute the Program (or any work based on the Program), ",
"the recipient automatically receives a license from the original licensor to ",
"copy, distribute or modify the Program subject to these terms and conditions. ",
"You may not impose any further restrictions on the recipients' exercise of ",
"the rights granted herein. You are not responsible for enforcing compliance ",
"by third parties to this License. ",
"\n\n",
"7. If, as a consequence of a court judgment or allegation of patent ",
"infringement or for any other reason (not limited to patent issues), ",
"conditions are imposed on you (whether by court order, agreement or ",
"otherwise) that contradict the conditions of this License, they do not excuse ",
"you from the conditions of this License. If you cannot distribute so as to ",
"satisfy simultaneously your obligations under this License and any other ",
"pertinent obligations, then as a consequence you may not distribute the ",
"Program at all. For example, if a patent license would not permit ",
"royalty-free redistribution of the Program by all those who receive copies ",
"directly or indirectly through you, then the only way you could satisfy both ",
"it and this License would be to refrain entirely from distribution of the ",
"Program. ",
"\n\n",
"If any portion of this section is held invalid or unenforceable under any ",
"particular circumstance, the balance of the section is intended to apply and ",
"the section as a whole is intended to apply in other circumstances. ",
"\n\n",
"It is not the purpose of this section to induce you to infringe any patents ",
"or other property right claims or to contest validity of any such claims; ",
"this section has the sole purpose of protecting the integrity of the free ",
"software distribution system, which is implemented by public license ",
"practices. Many people have made generous contributions to the wide range of ",
"software distributed through that system in reliance on consistent ",
"application of that system; it is up to the author/donor to decide if he or ",
"she is willing to distribute software through any other system and a licensee ",
"cannot impose that choice. ",
"\n\n",
"This section is intended to make thoroughly clear what is believed to be a ",
"consequence of the rest of this License. ",
"\n\n",
"8. If the distribution and/or use of the Program is restricted in certain ",
"countries either by patents or by copyrighted interfaces, the original ",
"copyright holder who places the Program under this License may add an ",
"explicit geographical distribution limitation excluding those countries, so ",
"that distribution is permitted only in or among countries not thus excluded. ",
"In such case, this License incorporates the limitation as if written in the ",
"body of this License. ",
"\n\n",
"9. The Free Software Foundation may publish revised and/or new versions of ",
"the General Public License from time to time. Such new versions will be ",
"similar in spirit to the present version, but may differ in detail to address ",
"new problems or concerns. ",
"\n\n",
"Each version is given a distinguishing version number. If the Program ",
"specifies a version number of this License which applies to it and \"any later ",

"that version or of any later version published by the Free Software ",
"Foundation. If the Program does not specify a version number of this License, ",
"you may choose any version ever published by the Free Software Foundation. ",
"\n\n",
"10. If you wish to incorporate parts of the Program into other free programs ",
"whose distribution conditions are different, write to the author to ask for ",
"permission. For software which is copyrighted by the Free Software ",
"Foundation, write to the Free Software Foundation; we sometimes make ",
"exceptions for this. Our decision will be guided by the two goals of ",

"menu of the preferences menu in NEdit.  Users with the explicit focus ",

"being set to False (generally a bad choice for explicit focus users). ",
"NCDwm users should use the focus model \"click\" instead of \"explicit\", ",
"again, unless you have set it that way to correct specific problems, this ",

"\01IThe Tabs dialog controls both the operation of the Tab key, and ",
"the interpretation of tab characters within a file. ",
"\n\n",
"The first field, Tab Spacing, controls how  NEdit responds to ",
"tab characters in a file.  On most Unix and VMS systems the ",
"conventional interpretation of a tab character is to advance the ",
"text position to the nearest multiple of eight characters (a tab ",
"spacing of 8).  However, many programmers of C and other ",
"structured languages, when given the choice, prefer a tab ",
"spacing of 3 or 4 characters.  Setting a three or four character ",
"hardware tab spacing is useful and convenient as long as your ",
"other software tools support it.  Unfortunately, on Unix and VMS ",
"systems, system utilities, such as more, and printing software ",
"can't always properly display files with other than eight ",
"character tabs. ",
"\n\n",
"Selecting \"Emulate Tabs\" will cause the Tab key to insert the ",
"correct number of spaces or tabs to reach the next tab stop, as ",
"if the tab spacing were set at the value in the \"Emulated tab ",
"spacing\" field.  Backspacing immediately after entering an ",
"emulated tab will delete it as a unit, but as soon as you move ",
"the cursor away from the spot, NEdit will forget that the ",
"collection of spaces and tabs is a tab, and will treat it as ",
"separate characters.  To enter a real tab character with ",
"\"Emulate Tabs\" turned on, use Ctrl+Tab. ",
"\n\n",
"In generating emulated tabs, and in Shift Left, Paste Column, ",
"and some rectangular selection operations, NEdit inserts blank ",
"characters (spaces or tabs) to preserve the alignment of ",
"non-blank characters. The bottom toggle button in the Tabs ",
"dialog instructs NEdit whether to insert tab characters as ",
"padding in such situations. Turning this off, will keep NEdit ",

** A subroutine to put up a calltip
** First arg is either text to be displayed or a key for tip/tag lookup.
** Optional second arg is the buffer position beneath which to display the 
**      upper-left corner of the tip.  Default (or -1) puts it under the cursor.
** Additional optional arguments:
**      "tipText": (default) Indicates first arg is text to be displayed in tip.
**      "tipKey":   Indicates first arg is key in calltips database.  If key
**                  is not found in tip database then the tags database is also 
**                  searched.
**      "tagKey":   Indicates first arg is key in tags database.  (Skips 
**                  search in calltips database.)
**      "center":   Horizontally center the calltip at the position
**      "right":    Put the right edge of the calltip at the position
**                  "center" and "right" cannot both be specified.
**      "above":    Place the calltip above the position
**      "strict":   Don't move the calltip to keep it on-screen and away
**                  from the cursor's line.
** 
** Returns the new calltip's ID on success, 0 on failure.
**
** Does this need to go on IgnoredActions?  I don't think so, since
** showing a calltip may be part of the action you want to learn.

   iso8859 appears to be necessary for newer versions of XFree86 that

   (This of course, is a stupid default because there are far more iso8859
   apps than Unicode apps.  But the X folks insist it's a client bug.  Hah.)

   RedHat 7.3 won't default to '-1' for an encoding, if left with a *,

/* OPCODE NOTES:
   ------------

   All nodes consist of an 8 bit op code followed by 2 bytes that make up a 16
   bit NEXT pointer.  Some nodes have a null terminated character string operand
   following the NEXT pointer.  Other nodes may have an 8 bit index operand.
   The TEST_COUNT node has an index operand followed by a 16 bit test value.
   The BRACE and LAZY_BRACE nodes have two 16 bit values for min and max but no
   index value.

   SIMILAR
      Operand(s): null terminated string

      Implements a case insensitive match of a string.  Mostly intended for use
      in syntax highlighting patterns for keywords of languages like FORTRAN
      and Ada that are case insensitive.  The regex text in this node is
      converted to lower case during regex compile.

   DIGIT, NOT_DIGIT, LETTER, NOT_LETTER, SPACE, NOT_SPACE, WORD_CHAR,
   NOT_WORD_CHAR
      Operand(s): None

      Implements shortcut escapes \d, \D, \l, \L, \s, \S, \w, \W.  The locale
      aware ANSI functions isdigit(), isalpha(), isalnun(), and isspace() are
      used to implement these in the hopes of increasing portability.

   NOT_BOUNDARY
      Operand(s): None

      Implements \B as a zero width assertion that the current character is
      NOT on a word boundary.  Word boundaries are defined to be the position
      between two characters where one of those characters is one of the
      dynamically defined word delimiters, and the other character is not.

   IS_DELIM
      Operand(s): None

      Implements \y as any character that is one of the dynamically
      specified word delimiters.

   NOT_DELIM
      Operand(s): None

      Implements \Y as any character that is NOT one of the dynamically
      specified word delimiters.

   STAR, PLUS, QUESTION, and complex '*', '+', and '?'
      Operand(s): None (Note: NEXT pointer is usually zero.  The code that
                        processes this node skips over it.)

      Complex (parenthesized) versions implemented as circular BRANCH
      structures using BACK.  SIMPLE versions (one character per match) are
      implemented separately for speed and to minimize recursion.

   BRACE, LAZY_BRACE
      Operand(s): minimum value (2 bytes), maximum value (2 bytes)

      Implements the {m,n} construct for atoms that are SIMPLE.

   BRANCH
      Operand(s): None

      The set of branches constituting a single choice are hooked together
      with their NEXT pointers, since precedence prevents anything being
      concatenated to any individual branch.  The NEXT pointer of the last
      BRANCH in a choice points to the thing following the whole choice.  This
      is also where the final NEXT pointer of each individual branch points;
      each branch starts with the operand node of a BRANCH node.

   BACK
      Operand(s): None

      Normal NEXT pointers all implicitly point forward.  Back implicitly
      points backward.  BACK exists to make loop structures possible.

   INIT_COUNT
      Operand(s): index (1 byte)

      Initializes the count array element referenced by the index operand.
      This node is used to build general (i.e. parenthesized) {m,n} constructs.

   INC_COUNT
      Operand(s): index (1 byte)

      Increments the count array element referenced by the index operand.
      This node is used to build general (i.e. parenthesized) {m,n} constructs.

   TEST_COUNT
      Operand(s): index (1 byte), test value (2 bytes)

      Tests the current value of the count array element specified by the
      index operand against the test value.  If the current value is less than
      the test value, control passes to the node after that TEST_COUNT node.
      Otherwise control passes to the node referenced by the NEXT pointer for
      the TEST_COUNT node.  This node is used to build general (i.e.
      parenthesized) {m,n} constructs.

   BACK_REF, BACK_REF_CI
      Operand(s): index (1 byte, value 1-9)

      Implements back references.  This node will attempt to match whatever text
      was most recently captured by the index'th set of parentheses.
      BACK_REF_CI is case insensitive version.

   X_REGEX_BR, X_REGEX_BR_CI
      (NOT IMPLEMENTED YET)

      Operand(s): index (1 byte, value 1-9)

      Implements back references into a previously matched but separate regular
      expression.  This is used by syntax highlighting patterns. This node will
      attempt to match whatever text was most captured by the index'th set of
      parentheses of the separate regex passed to ExecRE. X_REGEX_BR_CI is case
      insensitive version.

   POS_AHEAD_OPEN, NEG_AHEAD_OPEN, LOOK_AHEAD_CLOSE

      Operand(s): None

      Implements positive and negative look ahead.  Look ahead is an assertion
      that something is either there or not there.   Once this is determined the
      regex engine backtracks to where it was just before the look ahead was
      encountered, i.e. look ahead is a zero width assertion.

   POS_BEHIND_OPEN, NEG_BEHIND_OPEN, LOOK_BEHIND_CLOSE

      Operand(s): 2x2 bytes for OPEN (match boundaries), None for CLOSE

      Implements positive and negative look behind.  Look behind is an assertion
      that something is either there or not there in front of the current
      position.  Look behind is a zero width assertion, with the additional
      constraint that it must have a bounded length (for complexity and
      efficiency reasons; note that most other implementation even impose
      fixed length).

   OPEN, CLOSE

      Operand(s): None

      OPEN  + n = Start of parenthesis 'n', CLOSE + n = Close of parenthesis
      'n', and are numbered at compile time.

 * ExecRE - match a `regexp' structure against a string
 *
 * If `end' is non-NULL, matches may not BEGIN past end, but may extend past
 * it.  If reverse is true, `end' must be specified, and searching begins at
 * `end'.  "isbol" should be set to true if the beginning of the string is the
 * actual beginning of a line (since `ExecRE' can't look backwards from the
 * beginning to find whether there was a newline before).  Likewise, "isbow"
 * asks whether the string is preceded by a word delimiter.  End of string is
 * always treated as a word and line boundary (there may be cases where it
 * shouldn't be, in which case, this should be changed).  "delimit" (if
 * non-null) specifies a null-terminated string of characters to be considered
 * word delimiters matching "<" and ">".  if "delimit" is NULL, the default
 * delimiters (as set in SetREDefaultWordDelimiters) are used. 
 * Look_behind_to indicates the position till where it is safe to
 * perform look-behind matches. If set, it should be smaller than or equal
 * to the start position of the search (pointed at by string). If it is NULL, 
 * it defaults to the start position.
 * Finally, match_to indicates the logical end of the string, till where 
 * matches are allowed to extend. Note that look-ahead patterns may look
 * past that boundary. If match_to is set to NULL, the terminating \0 is
 * assumed to correspond to the logical boundary. Match_to, if set, must be 
 * larger than or equal to end, if set.

       buffer which then differ from the real (displayed) buffer are used to
       replace those parts, thus one replace operation serves as both undo
       and modify.  This double-buffering of the operation prevents excessive
       redrawing (though there is still plenty of needless redrawing due to
       re-selection and rectangular operations).
       
       The hard part is keeping track of the changes such that a single replace
       operation will do everyting.  This is done using a routine called
       trackModifyRange which tracks expanding ranges of changes in the two
       buffers in modRangeStart, tempModRangeEnd, and bufModRangeEnd. */

       be at least 30 characters, which is probably unacceptable.
       Amazingly, adding a top offset of 1 pixel to the toggle buttons of 
       the i-search bar, while keeping the the top offset of the text widget 
       to 0 seems to avoid avoid the crash. */

       closed, in the middle of keystrokes learning, by clicking on the 
       close-tab button.
       
       As evident to our accusation, the coredump may be surpressed by 
       simply commenting out the XtRemoveActionHook() call. The bug was
       consistent on both Motif and Lesstif on various platforms.

       Closing the tab through either the "Close" menu or its accel key, 
       however, was without any trouble.
       
       While its actual mechanism is not well understood, we somehow

       the tab. For now. */

* function to put up modal versions of the XmCreateDialog functions      *
* (where  is Error, Information, Prompt, Question, Message, or Warning). *

* invoked in-line without giving control back to the main loop. The message    *
* string can contain vsprintf specifications.                                  *
* DialogF displays the dialog in application-modal style, blocking the         *
* application and keeping the modal dialog as the top window until the user    *
* responds. DialogF accepts a variable number of arguments, so the calling     *
* routine needs to #include . The first button is automatically      *
* marked as the default button (activated when the user types Return,          *
* surrounded by a special outline), and any button named either Cancel, or     *
* Dismiss is marked as the cancel button (activated by the ESC key). Buttons   *
* marked Dismiss or Cancel are also triggered by close of dialog via the       *
* window close box. If there's no Cancel or Dismiss button, button 1 is        *

/*
** Manage a list widget and a set of buttons which represent a list of
** records.  The caller provides facilities for editing the records
** individually, and this code handles the organization of the overall list,
** such that the user can modify, add, and delete records, and re-order the
** list.
**
** The format for the list of records managed by this code should be an
** array of size "maxItems" of pointers to record structures.  The records
** themselves can be of any format, but the first field of the structure
** must be a pointer to a character string which will be displayed as the
** item name in the list.  The list "itemList", and the number of items
** "nItems" are automatically updated by the list management routines as the
** user makes changes.
**
** The caller must provide routines for transferring data to and from the
** dialog fields dedicated to displaying and editing records in the list.
** The callback "setDialogDataCB" must take the contents of the item pointer
** passed to it, and display the data it contains, erasing any previously
** displayed data.  The format of the setDialogData callback is:
**
**    void setDialogDataCB(void *item, void *cbArg)
**
**	 item:	a pointer to the record to be displayed
**
**  	 cbArg:	an arbitrary argument passed on to the callback routine
**
** The callback "setDialogDataCB" must allocate (with XtMalloc) and return a
** new record reflecting the current contents of the dialog fields.  It may
** do error checking on the data that the user has entered, and can abort
** whatever operation triggered the request by setting "abort" to True.
** This routine is called in a variety of contexts, such as the user
** clicking on a list item, or requesting that a copy be made of the current
** list item.  To aide in communicating errors to the user, the boolean value
** "explicitRequest" distinguishes between the case where the user has
** specifically requested that the fields be read, and the case where he
** may be surprised that errors are being reported, and require further
** explanation.  The format of the getDialogData callback is:
**
**    void *getDialogDataCB(void *oldItem, int explicitRequest, int *abort,
**  	      void *cbArg)
**
**	 oldItem: a pointer to the existing record being modified in the
**	    dialog, or NULL, if the user is modifying the "New" item.
**
**	 explicitRequest: True if the user directly asked for the records
**	    to be changed (as with an OK or Apply button).  If a less direct
**	    process resulted in the request, the user might need extra
**	    explanation and possibly a chance to proceed using the existing
**	    stored data (to use the data from oldItem, the routine should
**	    make a new copy).
**
**	 abort: Can be set to True if the dialog fields contain errors.
**	    Setting abort to True, stops whetever process made the request
**	    for updating the data in the list from the displayed data, and
**	    forces the user to remain focused on the currently displayed
**	    item until he either gives up or gets it right.
**
**	 cbArg: arbitrary data, passed on from where the callback was
**	    established in the list creation routines
**
**    The return value should be an allocated
**
** The callback "freeItemCB" should free the item passed to it:
**
**    void freeItemCB(void *item, void *cbArg)
**
**	 item:	a pointer to the record to be freed
**
** The difference between ManageListAndButtons and CreateManagedList, is that
** in this routine, the caller creates the list and button widgets and passes
** them here so that they be arranged explicitly, rather than relying on the
** default style imposed by CreateManagedList.  ManageListAndButtons simply
** attaches the appropriate callbacks to process mouse and keyboard input from
** the widgets.

** Older X applications and X servers were mostly designed to operate with

** 8-bit PseudoColor, because some of their X applications don't work
** properly with the other color models.  The problem with PseudoColor, of
** course, is that users run out of colors in the default colormap, and if
** they install additional colormaps for individual applications, colors
** flash and change weirdly when you change your focus from one application
** to another.
**
** In addition to the poor choice of default, a design flaw in Xt makes it
** impossible even for savvy users to specify the XtNvisual resource to
** switch to a deeper visual.  The problem is that the colormap resource is
** processed independently of the visual resource, and usually results in a
** colormap for the default visual rather than for the user-selected one.
**
** This routine should be called before creating a shell widget, to
** pre-process the visual, depth, and colormap resources, and return the
** proper values for these three resources to be passed to XtAppCreateShell.
** Applications which actually require a particular color model (i.e. for
** doing color table animation or dynamic color assignment) should not use
** this routine.
**
** Note that a consequence of using the "best" as opposed to the default
** visual is that some color resources are still converted with the default
** visual (particularly *background), and these must be avoided by widgets
** which are allowed to handle any visual.

 *     #define LESSTIF_VERSION  0
 *     #define LESSTIF_REVISION 93
 *     #define LesstifVersion   (LESSTIF_VERSION * 1000 + LESSTIF_REVISION)

 *
 * Also, in LessTif the XmVERSION_STRING is identical to the

** Preferences File
**
** An application maintains a preferences file so that users can
** quickly save and restore program options from within a program,
** without being forced to learn the X resource mechanism.
**
** Preference files are the same format as X resource files, and
** are read using the X resource file reader.  X-savvy users are allowed
** to move resources out of a preferences file to their X resource
** files.  They would do so if they wanted to attach server-specific
** preferences (such as fonts and colors) to different X servers, or to
** combine additional preferences served only by X resources with those
** provided by the program's menus.
*/

/*
** Preference description table
**
** A preference description table contains the information necessary
** to read preference resources and store their values in a data
** structure.  The table can, so far, describe four types
** of values (this will probably be expanded in the future to include
** more types): ints, booleans, enumerations, and strings.  Each entry 
** includes the name and class for saving and restoring the parameter
** in X database format, the data type, a default value in the form of
** a character string, and the address where the parameter value is
** be stored.  Strings and enumerations take an additional argument.
** For strings, it is the maximum length string that can safely be
** stored or NULL to indicate that new space should be allocated and a
** pointer to it stored in the value address.  For enums, it is an array
** of string pointers to the names of each of its possible values. The
** last value in a preference record is a flag for determining whether
** the value should be written to the save file by SavePreferences.

/*******************
Implementation Note:
Q: Why aren't you using the Xt type conversion services?
A: 1) To create a save file, you also need to convert values back to text form,
and there are no converters for that direction.  2) XtGetApplicationResources
can only be used on the resource database created by the X toolkit at 
initialization time, and there is no way to intervene in the creation of
that database or store new resources in it reliably after it is created.
3) The alternative, XtConvertAndStore is not adequately documented.  The
toolkit mauual does not explain why it overwrites its input value structure.
4) XtGetApplicationResources and XtConvertAndStore do not work well together
because they use different storage strategies for certain data types.

   Determine which machine we were compiled with.  This isn't as accurate
   as calling uname(), which is preferred.  However, this gets us very close
   for a majority of the machines out there, and doesn't require any games
   with make.

   A better, but trickier solution, is to run uname at compile time, capture
   the string, and place it in the executable.
      
   Please update this with the proper symbols for your compiler/CPU.  It
   may take a little sleuthing to find out what the correct symbol is.
   Better compilers/OSs document the symbols they define, but not all do.
   Usually, the correct ones are prepended with an _ or __, as this is
   namespace is reserved by ANSI C for the compiler implementation.
   
   The order is important for the x86 macros.  Some compilers will
   simultanenously define __i386 and __pentium, so we pick the highest one.

   Some of the info below derived from these excellent references:

*			       done with the string.)			       *
*	 NulStrToDesc	   - Convert C-like null-terminated string to VMS      *
*			       String Descriptor.  Returns the address of      *
*			       the malloc'd descriptor, which should be free'd *
*			       when done by calling FreeStrDesc().  	       *
*	 NulStrWrtDesc	   - Convert C-like null-terminated string to VMS      *
*			       String Descriptor for writing into.  The C      *
*			       String should already be allocated and the      *

*			       the address of the malloc'd descriptor, which   *
*			       should be free'd when done via FreeStrDesc().   *
*	 FreeNulStr	   - Frees null-terminated strings created by 	       *
*			       StrDescToNul(). 				       *
*	 FreeStrDesc 	   - Frees VMS String Descriptors created by 	       *
*			       NulStrToDesc() and NulStrWrtDesc(). 	       *
*	 ConvertVMSCommandLine	- Convert an argument vector representing a    *
*			       VMS-style command line to something Unix-like.  *
*			       Limitations: no abbreviations, some syntax      *
*			       information is lost so some errors will yield   *
*			       strange results.				       * 
*									       *
*	 rint   	   - Returns the integer (represented as a double      *
*			       precision number) nearest its double argument.  *
*									       *
*	 VMSFileScan   	   - Calls LIB$FILE_SCAN for filenames on VMS systems  *
*									       *
*	 VMSFileScanDone   - Ends LIB$FILE_SCAN context & frees memory used    *
*                                                                              *
