Xterm is being improved even now. You need only set the standard locale environment variables such as LC_CTYPE, LC_ALL, LC_CTYPE, or LANG. Once the locale is set up you can use xterm in your favorite character encoding. This document explains how the i18n feature is realized and how to configure xterm for your character encoding. Refer to locale(7) for details of the locale mechanism. Basic i18n-related settings and resources ========================================= These settings apply to XFree86 xterm patch #181, and the program luit which is distributed with XFree86 4.4 1. Usage of "locale mode" On startup, xterm must be in "locale mode" to make it follow the current locale. You can invoke xterm in locale mode in these ways: a. Set "vt100.locale" resource "true". This resource was introduced since XFree86 4.3. The default value of the "locale" resource is "medium", which means xterm follows the locale only in Chinese, Japanese, Korean, or Thai locales. For example, XTerm*locale: true in your ~/.Xresources file. or b. Invoke xterm with the "-lc" option. 2. Converter program "luit" The "luit" must be available in the standard XFree86 binary directory. It is usually available because it is part of the XFree86 distribution. The standard binary directory may differ from system to system. /usr/X11R6/bin/luit is an example. "luit" is used to convert between Unicode and the character encoding for your locale. When built for XFree86, xterm includes logic for invoking luit. 3. Locale setting Finally, you will need to configure your locale. We expect that you have already configured your locale for other software. For example, LANG=de_DE@euro export LANG in your ~/.xsession file. There are many ways to configure locale. For example, your display manager may have a mechanism to invoke a window manager in your favorite locale, or you may have system-wide locale setting in /etc/environment. You may also have set the LC_ALL variable instead of the LANG variable. How to use xterm in different locale temporarily ================================================ You may sometimes need to invoke xterm in a different character encoding than your current locale. For example, use xterm to login remote systems in different locale. Do this by invoking xterm in the target locale. For example, $ LANG=ru_RU.KOI8-R xterm & Previously, font setting has been used in such cases. $ xterm -fn -misc-fixed-medium-r-normal--10-*-*-*-*-*-koi8-r & This does not work well in conjunction with the "locale" resource, because luit and xterm combined rely upon Unicode fonts. How to set fonts for UTF-8/locale modes ======================================= Since xterm patch #181, xterm can automatically use Unicode fonts in UTF-8 mode and locale mode. Few of you will need to modify the default setting to display your language. In particular, Unicode fonts in combination with locale mode will satisfy the needs of not only ISO-8859-1 users but also East Asian and other non-ISO-8859-1 users. If you want to set your favorite Unicode font for UTF-8 and locale modes, you should add a line such as the following in your ~/.Xresources file: XTerm*VT100.utf8Fonts.font: \ -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso10646-1 The leading "XTerm*" pattern is more specific than the system's app-defaults file, therefore it overrides the corresponding line beginning with *VT100.utf8Fonts.font: Here is an additional note. If you want to display East Asian doublewidth characters (CJK Ideogram, Hiragana, Katakana, Hangul, and so on), we recommend using -misc-fixed-medium-r-semicondensed--13-*-*-*-*-*-iso10646-1 or -misc-fixed-medium-r-normal--18-*-*-*-*-*-iso10646-1 because these two fonts have corresponding doublewidth fonts. These fonts are used as default font and default "Large" font, respectively. The internals of xterm i18n =========================== You do not need to read this section if you only want to configure your xterm. Here we describe how xterm is implemented to support i18n. The original version of xterm does not support locale or character encoding. Its I/O stream is interpreted as a mere 8-bit index for a font. Beginning with XFree86 4.0, xterm supported UTF-8. It was implemented as a separate UTF-8 mode from the conventional 8-bit mode. Character encodings had no effect on the 8-bit mode. The UTF-8 mode has been extended to support doublewidth characters (for East Asian characters) and combining characters (such as accents for Latin alphabets and Thai vowels/tone marks). Doublewidth characters are characters that occupy two continuing columns on the terminal. Xterm uses separate fonts for normal (singlewidth) characters and doublewidth characters. Though xterm has configuration items for specifying doublewidth fonts, it will automatically search for a font with exactly twice as wide and the same name as the specified normal font. The default behavior of xterm was modified to use this UTF-8 mode in UTF-8 locales. A command line option of "-u8" and a resource of "utf8" were introduced to choose UTF-8 mode. "luit" was introduced to XFree86 at version 4.2. It converts between UTF-8 and other encodings. When luit is invoked in a UTF-8 terminal, the terminal acts as if it is really running in the other encoding. Since XFree86 version 4.3, xterm provides a new mode to invoke luit automatically to support various encodings. The mode where xterm invokes luit is called "locale mode". It is the third mode following conventional 8-bit mode and UTF-8 mode. In the locale mode, xterm is aware of the current locale and character encoding. Since locale mode uses luit, it is based on the UTF-8 mode. That is, xterm works in UTF-8 mode and luit works as a converter between UTF-8 and the character encoding for your locale. This is why the locale mode always needs Unicode fonts. The default behavior of xterm is modified so that the "locale mode" will be adopted in Chinese (Big5 and GB2312), Japanese (EUC-JP), Korean (EUC-KR), and Thai (ISO-8859-11, as known as TIS-620) locales. Locale mode is chosen for these character encodings because these encodings are not supported by conventional 8-bit mode even by changing fonts (ISO-8859-11 needs combining characters and others need doublewidth characters). To control the locale mode, command line options of "-lc" and "-en" and a resource of "locale" were introduced. The command line option of "-u8" and a resource of "utf8" were made obsolete by them, though retained for compatibility. Since XFree86 version 4.4, xterm can have two sets of default fonts, one for conventional 8-bit mode and another for UTF-8 and locale modes, by introducing the "utf8Fonts" subresource. Future TODO Items ================= We anticipate that xterm's locale mode will be used increasingly in the future. Since the UTF-8 and locale modes use more resources than conventional 8-bit mode (because it needs larger fonts and another process "luit"), faster hardware may be needed to gain complete acceptance by users. However, the locale mechanism allows users to manipulate data in a standard form. Its usefulness compensates in part for reduced performance. Xterm supports antialiased fonts ("-fa" and "-fs" command line options). Currently UTF-8 nor locale modes do not work with antialiased fonts. Xterm does not support bi-directional or RTL languages such as Hebrew and Arab. A simple standard how terminal should behave for these languages is needed. Xterm does not support Unicode characters above U+10000. xterm-330/XTerm-col.ad0000644000175100001440000001330211241555255013363 0ustar tomusers! $XTermId: XTerm-col.ad,v 1.22 2009/08/15 15:56:29 tom Exp $ ! ----------------------------------------------------------------------------- ! this file is part of xterm ! !

If you want 8-bit charset selections to work as before, use "eightBitSelectTypes" XTerm resource setting.

It provides DEC VT102/VT220 and Tektronix 4014 compatible terminals for programs that can't use the window system directly. If the underlying operating system supports terminal resizing capabilities (for example, the SIGWINCH signal in systems derived from 4.3bsd), xterm will use the facilities to notify programs running in the window whenever it is resized.

It provides DEC VT102 and Tektronix 4014 compatible terminals for programs that cannot use the window system directly. This version implements ISO/ANSI colors, Unicode, and most of the control sequences used by DEC VT220 terminals. . This package contains a development version of xterm. It is configured to use "xterm-dev" and "XTermDev" for the program and its resource class, to avoid conflict with other packages. xterm-330/package/debian/xterm-dev.menu0000644000175100001440000000076213112654236016665 0ustar tomusers?package(xterm-dev):\ needs="x11"\ section="Applications/Terminal Emulators"\ longtitle="XTerm: terminal emulator for X (development)"\ title="XTermDev"\ icon="/usr/share/pixmaps/xterm-dev-color_32x32.xpm"\ command="xterm-dev" ?package(xterm-dev):\ needs="x11"\ section="Applications/Terminal Emulators"\ longtitle="XTerm: terminal emulator for X with Unicode support (development)"\ title="XTermDev (Unicode)"\ icon="/usr/share/pixmaps/xterm-dev-color_32x32.xpm"\ command="uxterm-dev" xterm-330/package/debian/watch0000644000175100001440000000014211460700355015103 0ustar tomusersversion=3 opts=passive ftp://invisible-island.net/xterm/current/xterm\.tar.gz \ debian uupdate xterm-330/package/debian/postinst0000644000175100001440000000053212424252524015664 0ustar tomusers#! /bin/sh echo "** postinst script for xterm: $*" set -e PRI=60 ALT=x-terminal-emulator PKG=xterm-dev BINDIR=/usr/bin MANDIR=/usr/share/man/man1 if [ $1 != "upgrade" ] then update-alternatives \ --install \ $BINDIR/$ALT $ALT \ $BINDIR/$PKG $PRI \ --slave $MANDIR/$ALT.1.gz $ALT.1.gz \ $MANDIR/$PKG.1.gz fi #DEBHELPER# exit 0 xterm-330/package/debian/source/0000755000175100001440000000000011410226414015347 5ustar tomusersxterm-330/package/debian/source/format0000644000175100001440000000001511410226414016556 0ustar tomusers3.0 (native) xterm-330/package/debian/prerm0000644000175100001440000000026712424250520015125 0ustar tomusers#! /bin/sh echo "** prerm script for xterm: $*" set -e if [ "x$1" != "xupgrade" ]; then update-alternatives --remove x-terminal-emulator /usr/bin/xterm-dev fi #DEBHELPER# exit 0 xterm-330/package/debian/color.sed0000644000175100001440000000045611461060326015673 0ustar tomuserss/!

It provides DEC VT102 and Tektronix 4014 compatible terminals for programs that cannot use the window system directly. This version implements ISO/ANSI colors, Unicode, and most of the control sequences used by DEC VT220 terminals. This package provides four commands: a) %{fullname}, which is the actual terminal emulator b) u%{fullname}, which is a wrapper around %{fullname} which sets %{fullname} to use UTF-8 encoding when the user's locale supports this, c) koi8r%{fullname}, a wrapper similar to u%{fullname} for locales that use the KOI8-R character set, and d) resize%{my_suffix}. A complete list of control sequences supported by the X terminal emulator is provided in /usr/share/doc/%{fullname}. The %{fullname} program uses bitmap images provided by the xbitmaps package. Those interested in using koi8r%{fullname} will likely want to install the xfonts-cyrillic package as well. This package is configured to use "%{fullname}" and "%{my_class}" for the program and its resource class, to avoid conflict with other packages. %prep %global desktop_vendor dickey %define desktop_utils %(if which desktop-file-install 2>&1 >/dev/null ; then echo 1 || echo 0 ; fi) %define icon_theme %(test -d /usr/share/icons/hicolor && echo 1 || echo 0) %define apps_x11r6 %(test -d /usr/X11R6/lib/X11/app-defaults && echo 1 || echo 0) %define apps_shared %(test -d /usr/share/X11/app-defaults && echo 1 || echo 0) %define apps_syscnf %(test -d /etc/X11/app-defaults && echo 1 || echo 0) %if %{apps_x11r6} %define _xresdir %{_prefix}/X11R6/lib/X11/app-defaults %else %if %{apps_shared} %define _xresdir %{_datadir}/X11/app-defaults %else %define _xresdir %{_sysconfdir}/X11/app-defaults %endif %endif %define _iconsdir %{_datadir}/icons %define _pixmapsdir %{_datadir}/pixmaps %define my_docdir %{_datadir}/doc/%{fullname} # no need for debugging symbols... %define debug_package %{nil} %setup -q -n xterm-%{version} %build CPPFLAGS="-DMISC_EXP -DEXP_HTTP_HEADERS" \ %configure \ --target %{_target_platform} \ --prefix=%{_prefix} \ --bindir=%{_bindir} \ --datadir=%{_datadir} \ --mandir=%{_mandir} \ %if "%{my_suffix}" != "" --program-suffix=%{my_suffix} \ --without-xterm-symlink \ %endif %if "%{icon_theme}" --with-icon-symlink \ --with-icon-theme \ --with-icondir=%{_iconsdir} \ %endif --with-app-class=%{my_class} \ --disable-imake \ --enable-256-color \ --enable-88-color \ --enable-dabbrev \ --enable-dec-locator \ --enable-exec-xterm \ --enable-hp-fkeys \ --enable-load-vt-fonts \ --enable-logfile-exec \ --enable-logging \ --enable-mini-luit \ --enable-paste64 \ --enable-regis-graphics \ --enable-sco-fkeys \ --enable-screen-dumps \ --enable-sixel-graphics \ --enable-tcap-fkeys \ --enable-tcap-query \ --enable-toolbar \ --enable-wide-chars \ --enable-xmc-glitch \ --with-app-defaults=%{_xresdir} \ --with-pixmapdir=%{_pixmapsdir} \ --with-own-terminfo=%{_datadir}/terminfo \ --with-terminal-type=xterm-new \ --with-utempter \ --with-icon-name=mini.xterm \ --with-xpm make chmod u+w XTerm.ad cat >>XTerm.ad <\*('' to hint that it is private. .RE .TP 8 .B "modifyFunctionKeys\fP (class\fB ModifyFunctionKeys\fP)" Tells how to handle the special case where Control-, Shift-, Alt- or Meta-modifiers are used to add a parameter to the escape sequence returned by a (numbered) function-key. The default is \*(``2\*(''. The resource values are similar to \fBmodifyCursorKeys\fP: .RS .TP 5 \-1 permits the user to use shift- and control-modifiers to construct function-key strings using the normal encoding scheme. .TP 5 0 uses the old/obsolete behavior, i.e., the modifier is the first parameter. .TP 5 1 prefixes modified sequences with CSI. .TP 5 2 forces the modifier to be the second parameter if it would otherwise be the first. .TP 5 3 marks the sequence with a \*(``>\*('' to hint that it is private. .RE .IP If \fBmodifyFunctionKeys\fP is zero, \fI\*n\fP uses Control- and Shift-modifiers to allow the user to construct numbered function-keys beyond the set provided by the keyboard: .RS .TP 5 Control adds the value given by the \fBctrlFKeys\fP resource. .TP 5 Shift adds twice the value given by the \fBctrlFKeys\fP resource. .TP 5 Control/Shift adds three times the value given by the \fBctrlFKeys\fP resource. .RE .IP .TP 8 .B "modifyKeyboard\fP (class\fB ModifyKeyboard\fP)" Normally \fI\*n\fP makes a special case regarding modifiers (shift, control, etc.) to handle special keyboard layouts (\fBlegacy\fP and \fBvt220\fP). This is done to provide compatible keyboards for DEC VT220 and related terminals that implement user-defined keys (UDK). .IP The bits of the resource value selectively enable modification of the given category when these keyboards are selected. The default is \*(``0\*('': .RS .TP 5 0 The legacy/vt220 keyboards interpret only the Control-modifier when constructing numbered function-keys. Other special keys are not modified. .TP 5 1 allows modification of the numeric keypad .TP 5 2 allows modification of the editing keypad .TP 5 4 allows modification of function-keys, overrides use of Shift-modifier for UDK. .TP 5 8 allows modification of other special keys .RE .TP 8 .B "modifyOtherKeys\fP (class\fB ModifyOtherKeys\fP)" Like \fBmodifyCursorKeys\fP, tells \fI\*n\fP to construct an escape sequence for other keys (such as \*(``2\*('') when modified by Control-, Alt- or Meta-modifiers. This feature does not apply to function keys and well-defined keys such as ESC or the control keys. The default is \*(``0\*('': .RS .TP 5 0 disables this feature. .TP 5 1 enables this feature for keys except for those with well-known behavior, e.g., Tab, Backarrow and some special control character cases, e.g., Control-Space to make a NUL. .TP 5 2 enables this feature for keys including the exceptions listed. .RE .TP 8 .B "multiClickTime\fP (class\fB MultiClickTime\fP)" Specifies the maximum time in milliseconds between multi-click select events. The default is \*(``250\*('' milliseconds. .TP 8 .B "multiScroll\fP (class\fB MultiScroll\fP)" Specifies whether or not scrolling should be done asynchronously. The default is \*(``false\*(''. .TP 8 .B "nMarginBell\fP (class\fB Column\fP)" Specifies the number of characters from the right margin at which the margin bell should be rung, when enabled by the \fBmarginBell\fP resource. The default is \*(``10\*(''. .TP 8 .B "numColorRegisters\fP (class\fB NumColorRegisters\fP)" If \fI\*n\fR is configured to support ReGIS or SIXEL graphics, this specifies the number of color-registers which are available. .IP If this resource is not specified, \fI\*n\fR uses a value determined by the \fBdecTerminalID\fP resource: .TS l l _ _ r r. \fBResult\fR \fBdecTerminalID\fR 4 125 4 240 4 241 4 330 16 340 2 382 1024 \fIother\fP .TE .TP 8 .B "numLock\fP (class\fB NumLock\fP)" If \*(``true\*('', \fI\*n\fR checks if NumLock is used as a modifier (see \fIxmodmap\fP(__mansuffix__)). If so, this modifier is used to simplify the logic when implementing special NumLock for the \fBsunKeyboard\fP resource. Also (when \fBsunKeyboard\fP is false), similar logic is used to find the modifier associated with the left and right Alt keys. The default is \*(``true\*(''. .TP 8 .B "oldXtermFKeys\fP (class\fB OldXtermFKeys\fP)" If \*(``true\*('', \fI\*n\fR will use old-style (X11R5) escape sequences for function keys F1 to F4, for compatibility with X Consortium \fI\*n\fR. Otherwise, it uses the VT100 codes for PF1 to PF4. The default is \*(``false\*(''. .IP Setting this resource has the same effect as setting the \fBkeyboardType\fP to \fBlegacy\fP. The \fBkeyboardType\fP resource is the preferred mechanism for selecting this mode. .IP The old-style escape sequences resemble VT220 keys, but appear to have been invented for \fI\*n\fP in X11R4. .TP 8 .B "on2Clicks\fP (class\fB On2Clicks\fP)" .TP .B "on3Clicks\fP (class\fB On3Clicks\fP)" .TP .B "on4Clicks\fP (class\fB On4Clicks\fP)" .TP .B "on5Clicks\fP (class\fB On5Clicks\fP)" Specify selection behavior in response to multiple mouse clicks. A single mouse click is always interpreted as described in the \fBSelection Functions\fP section (see \fBPOINTER USAGE\fP). Multiple mouse clicks (using the button which activates the \fBselect-start\fP action) are interpreted according to the resource values of \fBon2Clicks\fP, etc. The resource value can be one of these: .RS .TP 3 word Select a \*(``word\*('' as determined by the \fBcharClass\fP resource. See the \fBCHARACTER CLASSES\fP section. .TP line Select a line (counting wrapping). .TP group Select a group of adjacent lines (counting wrapping). The selection stops on a blank line, and does not extend outside the current page. .TP page Select all visible lines, i.e., the page. .TP all Select all lines, i.e., including the saved lines. .TP regex Select a \*(``word\*('' as determined by the regular expression which follows in the resource value. .TP none No selection action is associated with this resource. \fI\*N\fP interprets it as the end of the list. For example, you may use it to disable triple (and higher) clicking by setting \fBon3Clicks\fP to \*(``none\*(''. .RE .IP The default values for \fBon2Clicks\fP and \fBon3Clicks\fP are \*(``word\*('' and \*(``line\*('', respectively. There is no default value for \fBon4Clicks\fP or \fBon5Clicks\fP, making those inactive. On startup, \fI\*n\fP determines the maximum number of clicks by the \fBon\fP\fIX\fP\fBClicks\fP resource values which are set. .TP 8 .B "openIm\fP (class\fB OpenIm\fP)" Tells \fI\*n\fP whether to open the input method at startup. The default is \*(``true\*(''. .TP 8 .B "pointerColor\fP (class\fB PointerColor\fP)" Specifies the foreground color of the pointer. The default is \*(``XtDefaultForeground\*(''. .TP 8 .B "pointerColorBackground\fP (class\fB PointerColorBackground\fP)" Specifies the background color of the pointer. The default is \*(``XtDefaultBackground\*(''. .TP 8 .B "pointerMode\fP (class\fB PointerMode\fP)" Specifies when the pointer may be hidden as the user types. It will be redisplayed if the user moves the mouse, or clicks one of its buttons. .RS .TP 3 0 never .TP 3 1 the application running in \fI\*n\fP has not activated mouse mode. This is the default. .TP 3 2 always. .RE .TP 8 .B "pointerShape\fP (class\fB Cursor\fP)" Specifies the name of the shape of the pointer. The default is \*(``xterm\*(''. .TP 8 .B "popOnBell\fP (class\fB PopOnBell\fP)" Specifies whether the window would be raised when Control-G is received. The default is \*(``false\*(''. .IP If the window is iconified, this has no effect. However, the \fBzIconBeep\fP resource provides you with the ability to see which iconified windows have sounded a bell. .TP 8 .B "precompose\fP (class\fB Precompose\fP)" Tells \fI\*n\fP whether to precompose UTF-8 data into Normalization Form C, which combines commonly-used accents onto base characters. If it does not do this, accents are left as separatate characters. The default is \*(``true\*(''. .TP 8 .B "preeditType\fP (class\fB PreeditType\fP)" Tells \fI\*n\fP which types of preedit (preconversion) string to display. The default is \*(``OverTheSpot,Root\*(''. .TP 8 .B "printAttributes\fP (class\fB PrintAttributes\fP)" Specifies whether to print graphic attributes along with the text. A real DEC VT\fIxxx\fP terminal will print the underline, highlighting codes but your printer may not handle these. .RS .bP \*(``0\*('' disables the attributes. .bP \*(``1\*('' prints the normal set of attributes (bold, underline, inverse and blink) as VT100-style control sequences. .bP \*(``2\*('' prints ANSI color attributes as well. .RE .IP The default is \*(``1\*(''. .TP 8 .B "printFileImmediate\fP (class \fBPrintFileImmediate\fP)" When the \fBprint-immediate\fP action is invoked, \fI\*n\fP prints the screen contents directly to a file. Set this resource to the prefix of the filename (a timestamp will be appended to the actual name). .IP The default is an empty string, i.e., \*(``\*('', However, when the \fBprint-immediate\fP action is invoked, if the string is empty, then \*(``__default_class__\*('' is used. .TP 8 .B "printFileOnXError\fP (class \fBPrintFileOnXError\fP)" If \fI\*n\fP exits with an X error, e.g., your connection is broken when the server crashes, it can be told to write the contents of the screen to a file. To enable the feature, set this resource to the prefix of the filename (a timestamp will be appended to the actual name). .IP The default is an empty string, i.e., \*(``\*('', which disables this feature. However, when the \fBprint-on-error\fP action is invoked, if the string is empty, then \*(``XTermError\*('' is used. .IP These error codes are handled: ERROR_XERROR, ERROR_XIOERROR and ERROR_ICEERROR. .TP 8 .B "printModeImmediate\fP (class \fBPrintModeImmediate\fP)" When the \fBprint-immediate\fP action is invoked, \fI\*n\fP prints the screen contents directly to a file. You can use the \fBprintModeImmediate\fP resource to tell it to use escape sequences to reconstruct the video attributes and colors. This uses the same values as the \fBprintAttributes\fP resource. The default is \*(``0\*(''. .TP 8 .B "printModeOnXError\fP (class \fBPrintModeOnXError\fP)" \fI\*N\fP implements the \fBprintFileOnXError\fP feature using the printer feature, although the output is written directly to a file. You can use the \fBprintModeOnXError\fP resource to tell it to use escape sequences to reconstruct the video attributes and colors. This uses the same values as the \fBprintAttributes\fP resource. The default is \*(``0\*(''. .TP 8 .B "printOptsImmediate\fP (class \fBPrintOptsImmediate\fP)" Specify the range of text which is printed to a file when the \fBprint-immediate\fP action is invoked. .RS .bP If zero (0), then this selects the current (visible screen) plus the saved lines, except if the alternate screen is being used. In that case, only the alternate screen is selectd. .bP If nonzero, the bits of this resource value (checked in descending order) select the range: .RS .TP 3 8 selects the saved lines. .TP 3 4 selects the alternate screen. .TP 3 2 selects the normal screen. .TP 3 1 selects the current screen, which can be either the normal or alternate screen. .RE .RE .IP The default is \*(``9\*('', which selects the current visible screen plus saved lines, with no special case for the alternated screen. .TP 8 .B "printOptsOnXError\fP (class \fBPrintOptsOnXError\fP)" Specify the range of text which is printed to a file when the \fBprint-on-error\fP action is invoked. The resource value is interpreted the same as in \fBprintOptsImmediate\fP. .IP The default is \*(``9\*('', which selects the current visible screen plus saved lines, with no special case for the alternated screen. .TP 8 .B "printerAutoClose\fP (class\fB PrinterAutoClose\fP)" If \*(``true\*('', \fI\*n\fR will close the printer (a pipe) when the application switches the printer offline with a Media Copy command. The default is \*(``false\*(''. .TP 8 .B "printerCommand\fP (class\fB PrinterCommand\fP)" Specifies a shell command to which .I \*n will open a pipe when the first MC (Media Copy) command is initiated. The default is an empty string, i.e., \*(``\*(''. If the resource value is given as an empty string, the printer is disabled. .TP 8 .B "printerControlMode\fP (class\fB PrinterControlMode\fP)" Specifies the printer control mode. A \*(``1\*('' selects autoprint mode, which causes .I \*n to print a line from the screen when you move the cursor off that line with a line feed, form feed or vertical tab character, or an autowrap occurs. Autoprint mode is overridden by printer controller mode (a \*(``2\*(''), which causes all of the output to be directed to the printer. The default is \*(``0\*(''. .TP 8 .B "printerExtent\fP (class\fB PrinterExtent\fP)" Controls whether a print page function will print the entire page (true), or only the portion within the scrolling margins (false). The default is \*(``false\*(''. .TP 8 .B "printerFormFeed\fP (class\fB PrinterFormFeed\fP)" Controls whether a form feed is sent to the printer at the end of a print page function. The default is \*(``false\*(''. .TP 8 .B "printerNewLine\fP (class\fB PrinterNewLine\fP)" Controls whether a newline is sent to the printer at the end of a print page function. The default is \*(``true\*(''. .TP 8 .B "privateColorRegisters\fP (class\fB PrivateColorRegisters\fP)" If \fI\*n\fR is configured to support ReGIS or SIXEL graphics, this controls whether \fI\*n\fR allocates separate color registers for each sixel device control string, e.g., for DECGCI. If not true, color registers are allocated only once, when the terminal is reset, and color changes in any graphic affect all graphics. The default is \*(``true\*(''. .TP 8 .B "quietGrab\fP (class\fB QuietGrab\fP)" Controls whether the cursor is repainted when \fINotifyGrab\fP and \fINotifyUngrab\fP event types are received during change of focus.

That is normally \*(``mono\*(''. .RE .TP 8 .B "resizeGravity\fP (class\fB ResizeGravity\fP)" Affects the behavior when the window is resized to be taller or shorter. \fBNorthWest\fP specifies that the top line of text on the screen stay fixed. If the window is made shorter, lines are dropped from the bottom; if the window is made taller, blank lines are added at the bottom. This is compatible with the behavior in R4. \fBSouthWest\fP (the default) specifies that the bottom line of text on the screen stay fixed. If the window is made taller, additional saved lines will be scrolled down onto the screen; if the window is made shorter, lines will be scrolled off the top of the screen, and the top saved lines will be dropped. .TP 8 .B "retryInputMethod\fP (class\fB RetryInputMethod\fP)" Tells \fI\*n\fP how many times to retry, in case the input-method server is not responding. This is a different issue than unsupported preedit type, etc. You may encounter retries if your X configuration (and its libraries) are missing pieces. Setting this resource to zero ``0'' will cancel the retrying. The default is ``3''. .TP 8 .B "reverseVideo\fP (class\fB ReverseVideo\fP)" Specifies whether or not reverse video should be simulated. The default is \*(``false\*(''. .IP There are several aspects to reverse video in \fI\*n\fP: .RS .bP The command-line \fB\-rv\fP option tells the X libraries to reverse the foreground and background colors. \fI\*N\fP's command-line options set resource values. In particular, the X Toolkit sets the \fBreverseVideo\fP resource when the \fB\-rv\fP option is used. .bP If the user has also used command-line options \fB\-fg\fP or \fB\-bg\fP to set the foreground and background colors, \fI\*n\fP does not see these options directly. Instead, it examines the resource values to reconstruct the command-line options, and determine which of the colors is the user's intended foreground, etc. Their actual values are irrelevant to the reverse video function; some users prefer the X defaults (black text on a white background), others prefer white text on a black background. .bP After startup, the user can toggle the \*(``Enable Reverse Video\*('' menu entry. This exchanges the current foreground and background colors of the VT100 widget, and repaints the screen. Because of the X resource hierarchy, the \fBreverseVideo\fP resource applies to more than the VT100 widget. .RE .IP Programs running in an \fI\*n\fP can also use control sequences to enable the VT100 reverse video mode. These are independent of the \fBreverseVideo\fP resource and the menu entry. \fI\*N\fP exchanges the current foreground and background colors when drawing text affected by these control sequences. .IP Other control sequences can alter the foreground and background colors which are used: .RS .bP Programs can also use the ANSI color control sequences to set the foreground and background colors. .bP Extensions to the ANSI color controls (such as 16-, 88- or 256-colors) are treated similarly to the ANSI control. .bP Using other control sequences (the \*(``\fIdynamic colors\fR\*('' feature), a program can change the foreground and background colors. .RE .TP 8 .B "reverseWrap\fP (class\fB ReverseWrap\fP)" Specifies whether or not reverse-wraparound should be enabled. This corresponds to \fI\*n\fP's private mode 45. The default is \*(``false\*(''. .TP 8 .B "rightScrollBar\fP (class\fB RightScrollBar\fP)" Specifies whether or not the scrollbar should be displayed on the right rather than the left.

The default is \*(``false\*(''. .TP 8 .B "scrollBarBorder\fP (class\fB ScrollBarBorder\fP)" Specifies the width of the scrollbar border. Note that this is drawn to overlap the border of the \fI\*n\fP window. Modifying the scrollbar's border affects only the line between the VT100 widget and the scrollbar. The default value is 1. .TP 8 .B "scrollKey\fP (class\fB ScrollCond\fP)" Specifies whether or not pressing a key should automatically cause the scrollbar to go to the bottom of the scrolling region. This corresponds to \fI\*n\fP's private mode 1011. The default is \*(``false\*(''. .TP 8 .B "scrollLines\fP (class\fB ScrollLines\fP)" Specifies the number of lines that the \fBscroll-back\fP and \fBscroll-forw\fP actions should use as a default.

The default is \*(``true\*(''. .TP .B "selectToClipboard\fP (class\fB SelectToClipboard\fP)" Tells \fI\*n\fP whether to use the \fBPRIMARY\fP or \fBCLIPBOARD\fP for \fBSELECT\fP tokens in the selection mechanism. The \fBset-select\fP action can change this at runtime, allowing the user to work with programs that handle only one of these mechanisms. The default is \*(``false\*('', which tells it to use \fBPRIMARY\fP. .TP 8 .B "shiftFonts\fP (class\fB ShiftFonts\fP)" Specifies whether to enable the actions \fBlarger-vt-font()\fP and \fBsmaller-vt-font()\fP, which are normally bound to the shifted KP_Add and KP_Subtract. The default is \*(``true\*(''. .TP 8 .B "showBlinkAsBold\fP (class\fB ShowBlinkAsBold\fP)" Tells \fI\*n\fP whether to display text with blink-attribute the same as bold. If \fI\*n\fP has not been configured to support blinking text, the default is \*(``true\*('', which corresponds to older versions of \fI\*n\fP, otherwise the default is \*(``false\*(''. .TP 8 .B "showMissingGlyphs\fP (class\fB ShowMissingGlyphs\fP)" Tells \fI\*n\fP whether to display a box outlining places where a character has been used that the font does not represent. The default is \*(``false\*(''. .TP 8 .B "showWrapMarks\fP (class\fB ShowWrapMarks\fP)" For debugging \fI\*n\fP and applications that may manipulate the wrapped-line flag by writing text at the right margin, show a mark on the right inner-border of the window. The mark shows which lines have the flag set. .TP 8 .B "signalInhibit\fP (class\fB SignalInhibit\fP)" Specifies whether or not the entries in the \fBMain Options\fP menu for sending signals to \fI\*n\fP should be disallowed. The default is \*(``false\*(''. .TP 8 .B "sixelScrolling\fP (class\fB SixelScrolling\fP)" If \fI\*n\fR is configured to support SIXEL graphics, this resource tells it whether to scroll up one line at a time when sixels would be written past the bottom line on the window. The default is \*(``false\*(''. .TP 8 .B "sixelScrollsRight\fP (class\fB SixelScrollsRight\fP)" If \fI\*n\fR is configured to support SIXEL graphics, this resource tells it whether to scroll to the right as needed to keep the current position visible rather than truncate the plot on the on the right. The default is \*(``false\*(''. .TP 8 .B "tekGeometry\fP (class\fB Geometry\fP)" Specifies the preferred size and position of the Tektronix window. There is no default for this resource. .TP 8 .B "tekInhibit\fP (class\fB TekInhibit\fP)" Specifies whether or not the escape sequence to enter Tektronix mode should be ignored. The default is \*(``false\*(''. .TP 8 .B "tekSmall\fP (class\fB TekSmall\fP)" Specifies whether or not the Tektronix mode window should start in its smallest size if no explicit geometry is given. This is useful when running \fI\*n\fP on displays with small screens. The default is \*(``false\*(''. .TP 8 .B "tekStartup\fP (class\fB TekStartup\fP)" Specifies whether or not \fI\*n\fP should start up in Tektronix mode. The default is \*(``false\*(''. .TP 8 .B "tiXtraScroll\fP (class\fB TiXtraScroll\fP)" Specifies whether \fI\*n\fP should scroll to a new page when processing the \fIti\fP termcap entry, i.e., the private modes 47, 1047 or 1049. This is only in effect if \fBtiteInhibit\fP is \*(``true\*('', because the intent of this option is to provide a picture of the full-screen application's display on the scrollback without wiping out the text that would be shown before the application was initialized. The default for this resource is \*(``false\*(''. .TP 8 .B "titeInhibit\fP (class\fB TiteInhibit\fP)" Originally specified whether or not \fI\*n\fP should remove \fIti\fP and \fIte\fP termcap entries (used to switch between alternate screens on startup of many screen-oriented programs) from the TERMCAP string. .IP TERMCAP is used rarely now, but \fI\*n\fP supports the feature on modern systems: .RS .bP If set, \fI\*n\fP also ignores the escape sequence to switch to the alternate screen. .bP \fI\*N\fP supports terminfo in a different way, supporting composite control sequences (also known as private modes) 1047, 1048 and 1049 which have the same effect as the original 47 control sequence. .RE .IP The default for this resource is \*(``false\*(''. .TP 8 .B "titleModes\fP (class\fB TitleModes\fP)" Tells \fI\*n\fP whether to accept or return window- and icon-labels in ISO-8859-1 (the default) or UTF-8. Either can be encoded in hexadecimal. The default for this resource is \*(``0\*(''. .IP Each bit (bit \*(``0\*('' is 1, bit \*(``1\*('' is 2, etc.) corresponds to one of the parameters set by the title modes control sequence: .RS .TP 5 0 Set window/icon labels using hexadecimal .TP 5 1 Query window/icon labels using hexadecimal .TP 5 2 Set window/icon labels using UTF-8 (overrides \fButf8Title\fP resource). .TP 5 3 Query window/icon labels using UTF-8 .RE .TP 8 .B "translations\fP (class\fB Translations\fP)" Specifies the key and button bindings for menus, selections, \*(``programmed strings\*('', etc. The \fBtranslations\fP resource, which provides much of \fI\*n\fP's configurability, is a feature of the X Toolkit Intrinsics library (Xt). See the \fBActions\fP section. .TP 8 .B "trimSelection\fP (class\fB TrimSelection\fP)" If you set \fBhighlightSelection\fP, you can see the text which is selected, including any trailing spaces. Clearing the screen (or a line) resets it to a state containing no spaces. Some lines may contain trailing spaces when an application writes them to the screen. However, you may not wish to paste lines with trailing spaces. If this resource is true, \fI\*n\fP will trim trailing spaces from text which is selected. It does not affect spaces which result in a wrapped line, nor will it trim the trailing newline from your selection. The default is \*(``false\*(''. .TP 8 .B "underLine\fP (class\fB UnderLine\fP)" This specifies whether or not text with the underline attribute should be underlined. It may be desirable to disable underlining when color is being used for the underline attribute. The default is \*(``true\*(''. .TP 8 .B "useClipping\fP (class\fB UseClipping\fP)" Tell \fI\*n\fP whether to use clipping to keep from producing dots outside the text drawing area. Originally used to work around for overstriking effects, this is also needed to work with some incorrectly-sized fonts. The default is \*(``true\*(''. .TP 8 .B "utf8\fP (class\fB Utf8\fP)" This specifies whether \fI\*n\fP will run in UTF-8 mode. If you set this resource, \fI\*n\fP also sets the \fBwideChars\fP resource as a side-effect. The resource can be set via the menu entry \*(``UTF-8 Encoding\*(''. The default is \*(``default\*(''. .IP \fI\*N\fP accepts either a keyword (ignoring case) or the number shown in parentheses: .RS .TP 3 false (0) UTF-8 mode is initially off. The command-line option \fB+u8\fP sets the resource to this value. Escape sequences for turning UTF-8 mode on/off are allowed. .TP true (1) UTF-8 mode is initially on. Escape sequences for turning UTF-8 mode on/off are allowed. .TP always (2) The command-line option \fB\-u8\fP sets the resource to this value. Escape sequences for turning UTF-8 mode on/off are ignored. .TP default (3) This is the default value of the resource. It is changed during initialization depending on whether the \fBlocale\fP resource was set, to false (0) or always (2). See the \fBlocale\fR resource for additional discussion of non-UTF-8 locales. .RE .IP If you want to set the value of \fButf8\fP, it should be in this range. Other nonzero values are treated the same as \*(``1\*('', i.e., UTF-8 mode is initially on, and escape sequences for turning UTF-8 mode on/off are allowed. .TP 8 .B "utf8Fonts\fP (class\fB Utf8Fonts\fP)" See the discussion of the \fBlocale\fP resource. This specifies whether \fI\*n\fP will use UTF-8 fonts specified via resource patterns such as \*(``\fB*vt100.utf8Fonts.font\fP\*('' or normal (ISO-8859-1) fonts via patterns such as \*(``\fB*vt100.font\fP\*(''. The resource can be set via the menu entry \*(``\fBUTF-8 Fonts\fP\*(''.

The menu entry is enabled, allowing the choice of fonts to be changed at runtime. .TP true (1) Use the UTF-8 fonts. The menu entry is enabled, allowing the choice of fonts to be changed at runtime. .TP always (2) Always use the UTF-8 fonts. This also disables the menu entry. .TP default (3) At startup, the resource is set to true or false, according to the effective value of the \fButf8\fP resource. .RE .TP 8 .B "utf8Latin1\fP (class\fB Utf8Latin1\fP)" If true, allow an ISO-8859-1 \fInormal\fP font to be combined with an ISO-10646-1 font if the latter is given via the \fB\-fw\fP option or its corresponding resource value. The default is \*(``false\*(''. .TP 8 .B "utf8SelectTypes\fP (class\fB Utf8SelectTypes\fP)" Override \fI\*n\fP's default selection target list (see \fBSELECT/PASTE\fP) for selections in wide-character (UTF-8) mode. The default is an empty string, i.e., \*(``\*('', which does not override anything. .TP 8 .B "utf8Title\fP (class\fB Utf8Title\fP)" Applications can set \fI\*n\fP's title by writing a control sequence. Normally this control sequence follows the VT220 convention, which encodes the string in ISO-8859-1 and allows for an 8-bit string terminator. If \fI\*n\fP is started in a UTF-8 locale, it translates the ISO-8859-1 string to UTF-8 to work with the X libraries which assume the string is UTF-8. .IP However, some users may wish to write a title string encoded in UTF-8. The window manager is responsible for drawing window titles. Some window managers (not all) support UTF-8 encoding of window titles. Set this resource to \*(``true\*('' to allow UTF-8 encoded title strings. That cancels the translation to UTF-8, allowing UTF-8 strings to be displayed as is. .IP This feature is available as a menu entry, since it is related to the particular applications you are running within \fI\*n\fP. You can also use a control sequence (see the discussion of \*(``Title Modes\*('' in \fI\*N Control Sequences\fP), to set an equivalent flag. The \fBtitleModes\fP resource sets the same value, which overrides this resource. .IP The default is \*(``false\*(''. .TP 8 .B "veryBoldColors\fP (class\fB VeryBoldColors\fP)" Specifies whether to combine video attributes with colors specified by \fBcolorBD\fR, \fBcolorBL\fR, \fBcolorIT\fR, \fBcolorRV\fR, and \fBcolorUL\fR. The resource value is the sum of values for each attribute: .RS 10 .nf 1 for reverse, 2 for underline, 4 for bold, 8 for blink, and 512 for italic .fi .RE .IP The default is \*(``0\*(''. .TP 8 .B "visualBell\fP (class\fB VisualBell\fP)" Specifies whether or not a visible bell (i.e., flashing) should be used instead of an audible bell when Control-G is received. The default is \*(``false\*('', which tells \fI\*n\fP to use an audible bell. .TP 8 .B "visualBellDelay\fP (class\fB VisualBellDelay\fP)" Number of milliseconds to delay when displaying a visual bell. Default is 100. If set to zero, no visual bell is displayed. This is useful for very slow displays, e.g., an LCD display on a laptop. .TP 8 .B "visualBellLine\fP (class\fB VisualBellLine\fP)" Specifies whether to flash only the current line when displaying a visual bell rather than flashing the entire screen: The default is \*(``false\*('', which tells \fI\*n\fP to flash the entire screen. .TP 8 .B "vt100Graphics\fP (class\fB VT100Graphics\fP)" This specifies whether \fI\*n\fP will interpret VT100 graphic character escape sequences while in UTF-8 mode. The default is \*(``true\*('', to provide support for various legacy applications. .TP 8 .B "wideBoldFont\fP (class\fB WideBoldFont\fP)" This option specifies the font to be used for displaying bold wide text. By default, it will attempt to use a font twice as wide as the font that will be used to draw bold text. If no double-width font is found, it will improvise, by stretching the bold font. .TP 8 .B "wideChars\fP (class\fB WideChars\fP)" Specifies if \fI\*n\fP should respond to control sequences that process 16-bit characters. The default is \*(``false\*(''. .TP 8 .B "wideFont\fP (class\fB WideFont\fP)" This option specifies the font to be used for displaying wide text. By default, it will attempt to use a font twice as wide as the font that will be used to draw normal text. If no double-width font is found, it will improvise, by stretching the normal font. .TP 8 .B "ximFont\fP (class\fB XimFont\fP)" This option specifies the font to be used for displaying the preedit string in the \*(``OverTheSpot\*('' input method. .IP In \*(``OverTheSpot\*('' preedit type, the preedit (preconversion) string is displayed at the position of the cursor. It is the XIM server's responsibility to display the preedit string. The XIM client must inform the XIM server of the cursor position. For best results, the preedit string must be displayed with a proper font. Therefore, \fI\*n\fP informs the XIM server of the proper font. The font is be supplied by a "fontset", whose default value is \*(``*\*(''. This matches every font, the X library automatically chooses fonts with proper charsets. The \fBximFont\fP resource is provided to override this default font setting. .\" .SS Tek4014 Widget Resources .PP The following resources are specified as part of the \fItek4014\fP widget (class \fITek4014\fP).

X applications generally do not care, since they see only \fIbutton events\fP which have .bP position and .bP button up/down state .PP \fI\*N\fP can see these events as long as it has \fIfocus\fP. .PP The keyboard also supplies events, but it is less flexible than the pointer for selecting/copying text. .PP \fIEvents\fP are applied to \fIactions\fP using the \fBtranslations\fP resource. See \fBActions\fP for a complete list, and \fBDefault Key Bindings\fP for the built-in set of \fBtranslations\fP resources. . .SS "Selection Functions" .PP The selection functions are invoked when the pointer buttons are used with no modifiers, and when they are used with the \*(``shift\*('' key. The assignment of the functions described below to keys and buttons may be changed through the resource database; see \fBActions\fP below. . .TP 5 Pointer button one (usually left) is used to save text into the cut buffer: .NS ~Meta :\fBselect-start\fP() .NE .IP Move the cursor to beginning of the text, and then hold the button down while moving the cursor to the end of the region and releasing the button. The selected text is highlighted and is saved in the global \fIcut buffer\fP and made the selection when the button is released: .NS :\fBselect-end\fP(\fBSELECT\fP, CUT_BUFFER0) \n\ .NE .IP Normally (but see the discussion of \fBon2Clicks\fP, etc): .RS .bP Double-clicking selects by words. .bP Triple-clicking selects by lines. .bP Quadruple-clicking goes back to characters, etc. .RE .IP Multiple-click is determined by the time from button up to button down, so you can change the selection unit in the middle of a selection. Logical words and lines selected by double- or triple-clicking may wrap across more than one screen line if lines were wrapped by \fI\*n\fP itself rather than by the application running in the window. If the key/button bindings specify that an X selection is to be made, \fI\*n\fP will leave the selected text highlighted for as long as it is the selection owner. . .TP 5 Pointer button two (usually middle) \*(``types\*('' (\fIpastes\fP) the text from the given selection, if any, otherwise from the cut buffer, inserting it as keyboard input: .NS ~Ctrl ~Meta :\fB\fBinsert-selection\fP\fP(\fBSELECT\fP, CUT_BUFFER0) .NE . .TP 5 Pointer button three (usually right) \fIextends\fP the current selection. .NS ~Ctrl ~Meta :\fB\fBstart-extend\fP\fP() .NE .IP (Without loss of generality, you can swap \*(``right\*('' and \*(``left\*('' everywhere in the rest of this paragraph.) If pressed while closer to the right edge of the selection than the left, it extends/contracts the right edge of the selection. If you contract the selection past the left edge of the selection, .I \*n assumes you really meant the left edge, restores the original selection, then extends/contracts the left edge of the selection. Extension starts in the selection unit mode that the last selection or extension was performed in; you can multiple-click to cycle through them. . .PP By cutting and pasting pieces of text without trailing new lines, you can take text from several places in different windows and form a command to the shell, for example, or take output from a program and insert it into your favorite editor. Since cut buffers are globally shared among different applications, you may regard each as a \*(``file\*('' whose contents you know. The terminal emulator and other text programs should be treating it as if it were a text file, i.e., the text is delimited by new lines. . .SS "Scrolling" .PP The scroll region displays the position and amount of text currently showing in the window (highlighted) relative to the amount of text actually saved. As more text is saved (up to the maximum), the size of the highlighted area decreases. . .PP Clicking button one with the pointer in the scroll region moves the adjacent line to the top of the display window. . .PP Clicking button three moves the top line of the display window down to the pointer position. . .PP Clicking button two moves the display to a position in the saved text that corresponds to the pointer's position in the scrollbar. . .SS "Tektronix Pointer" .PP Unlike the VT\fIxxx\fP window, the Tektronix window does not allow the copying of text. It does allow Tektronix GIN mode, and in this mode the cursor will change from an arrow to a cross. Pressing any key will send that key and the current coordinate of the cross cursor. Pressing button one, two, or three will return the letters \*(``l\*('', \*(``m\*('', and \*(``r\*('', respectively. If the \*(``shift\*('' key is pressed when a pointer button is pressed, the corresponding upper case letter is sent. To distinguish a pointer button from a key, the high bit of the character is set (but this is bit is normally stripped unless the terminal mode is RAW; see .IR tty (4) for details). . . .SH SELECT/PASTE X clients provide select and paste support by responding to requests conveyed by the server. .SS PRIMARY When configured to use the primary selection, (the default) \fI\*n\fP can provide the selection data in ways which help to retain character encoding information as it is pasted. .PP A user \*(``selects\*('' text on \*n, which highlights the selected text. A subsequent \*(``paste\*('' to another client forwards a request to the client owning the selection. If \fI\*n\fP owns the primary selection, it makes the data available in the form of one or more \*(``selection targets\*(''. If it does not own the primary selection, e.g., if it has released it or another client has asserted ownership, it relies on cut-buffers to pass the data. But cut-buffers handle only ISO-8859-1 data (officially \- some clients ignore the rules). . .SS CLIPBOARD When configured to use the clipboard (using the \fBselectToClipboard\fP resource), the problem with persistence of ownership is bypassed. Otherwise, there is no difference regarding the data which can be passed via selection. .PP The \fBPRIMARY\fP token is a standard X feature, documented in the ICCCM (\fIInter-Client Communication Conventions Manual\fR), which states .RS .PP The selection named by the atom \fBPRIMARY\fP is used for all commands that take only a single argument and is the principal means of communication between clients that use the selection mechanism. .RE .SS SELECT .PP However, many applications use \fBCLIPBOARD\fP in imitation of other windowing systems. The \fBselectToClipboard\fP resource (and corresponding menu entry \fBSelect to Clipboard\fP) introduce the SELECT token (known only to \fI\*n\fP) which chooses between the \fBPRIMARY\fP and \fBCLIPBOARD\fP tokens. .PP Without using this feature, one can use workarounds such as the \fIxclip\fP program to show the contents of the X clipboard within an \fI\*n\fP window. . .SS Selection Targets The different types of data which are passed depend on what the receiving client asks for. These are termed \fIselection targets\fP. .PP When asking for the selection data, \fI\*n\fP tries the following types in this order: .RS 5 .TP 5 UTF8_STRING This is an XFree86 extension, which denotes that the data is encoded in UTF-8. When \fI\*n\fP is built with wide-character support, it both accepts and provides this type. .TP 5 TEXT the text is in the encoding which corresponds to your current locale. .TP 5 .\" see xc/doc/specs/CTEXT/ctext.tbl.ms .\" (it says the data is stored as a type of ISO 2022) COMPOUND_TEXT this is a format for multiple character set data, such as multi-lingual text. It can store UTF-8 data as a special case. .TP 5 STRING This is Latin 1 (ISO-8859-1) data. .RE .PP The middle two (TEXT and COMPOUND_TEXT) are added if \fI\*n\fP is configured with the \fBi18nSelections\fP resource set to \*(``true\*(''. .PP UTF8_STRING is preferred (therefore first in the list) since \fI\*n\fP stores text as Unicode data when running in wide-character mode, and no translation is needed. On the other hand, TEXT and COMPOUND_TEXT may require translation. If the translation is incomplete, they will insert X's \*(``defaultString\*('' whose value cannot be set, and may simply be empty. \fI\*N\fP's \fBdefaultString\fP resource specifies the string to use for incomplete translations of the UTF8_STRING. .PP You can alter the types which \fI\*n\fP tries using the \fBeightBitSelectTypes\fP or \fButf8SelectTypes\fP resources. For instance, you might have some specific locale setting which does not use UTF-8 encoding. The resource value is a comma-separated list of the selection targets, which consist of the names shown. You can use the special name I18N to denote the optional inclusion of TEXT and COMPOUND_TEXT. The names are matched ignoring case, and can be abbreviated. The default list can be expressed in several ways, e.g., .sp .RS .nf UTF8_STRING,I18N,STRING utf8,i18n,string u,i,s .fi .RE . .SS Mouse Protocol .PP Applications can send escape sequences to \fI\*n\fP to cause it to send escape sequences back to the computer when you press a pointer button, or even (depending on which escape sequence) send escape sequences back to the computer as you move the pointer. .PP These escape sequences and the responses, called the \fImouse protocol\fP, are documented in \fIXTerm Control Sequences\fP. They do not appear in the \fIactions\fP invoked by the \fBtranslations\fP resource because the resource does not change while you run \fI\*n\fP, whereas applications can change the mouse prototol (i.e., enable, disable, use different modes). .PP However, the mouse protocol is interpreted within the \fIactions\fP that are usually associated with the pointer buttons. \fI\*N\fP ignores the mouse protocol in the \fBinsert-selection\fP action if the shift-key is pressed at the same time. It also modifies a few other actions if the shift-key is pressed, e.g., suppressing the response with the pointer position, though not eliminating changes to the selected text. . .SH MENUS . .PP \fI\*N\fP has four menus, named .IR mainMenu , .IR vtMenu , .IR fontMenu , and .IR tekMenu . Each menu pops up under the correct combinations of key and button presses. Each menu is divided into sections, separated by a horizontal line. Some menu entries correspond to modes that can be altered. A check mark appears next to a mode that is currently active. Selecting one of these modes toggles its state. Other menu entries are commands; selecting one of these performs the indicated function. .PP All of the menu entries correspond to X actions.

.SH SECURITY
.
.PP
X environments differ in their security consciousness.
.bP
Most servers,
run under \fIxdm\fP,
are capable of using a \*(``magic cookie\*('' authorization
scheme that can provide a reasonable level of security for many people.
If your server is only using a host-based mechanism to control access to
the server (see \fIxhost(__mansuffix__)\fP), then if you enable access for a host and
other users are also permitted to run clients on that same host,
it is possible that someone can run an application which uses the
basic services of the X protocol to snoop on your activities,
potentially capturing a transcript of everything you type at the keyboard.
.bP
Any process which has access to your X display can manipulate it
in ways that you might not anticipate,
even redirecting your keyboard to itself
and sending events to your application's windows.
This is true even with the \*(``magic cookie\*('' authorization scheme.
While the \fBallowSendEvents\fP provides some protection against
rogue applications tampering with your programs,
guarding against a snooper is harder.
.
.bP
The X input extension for instance allows an application to bypass
all of the other (limited) authorization and security features,
including the GrabKeyboard protocol.
.
.bP
The possibility of an application spying on your keystrokes
is of particular concern when you want to type in a password
or other sensitive data.
The best solution to this problem is to use a better
authorization mechanism than is provided by X.
.PP
Subject to all of these caveats,
a simple mechanism exists for protecting keyboard input in \fI\*n\fP.
.
.PP
The \fI\*n\fP menu (see \fBMENUS\fP above) contains a \fBSecure Keyboard\fP
entry which, when enabled,
attempts to ensure that all keyboard input is directed
\fIonly\fP to \fI\*n\fP (using the GrabKeyboard protocol request).
When an application prompts you for a password
(or other sensitive data), you can enable \fBSecure Keyboard\fP using the
menu, type in the data, and then disable \fBSecure Keyboard\fP using
the menu again.
.bP
This ensures that you know which window is accepting your keystrokes.
.bP
It cannot ensure that there are no processes which have access to your
X display that might be observing the keystrokes as well.
.
.PP
Only one X client at a time can grab the keyboard,
so when you attempt to enable \fBSecure Keyboard\fP it may fail.
In this case, the bell will sound.
If the \fBSecure Keyboard\fP succeeds,
the foreground and background colors will be exchanged (as if you
selected the \fBEnable Reverse Video\fP entry in the \fBModes\fP menu);
they will be exchanged again when you exit secure mode.
If the colors
do \fInot\fP switch, then
you should be \fIvery\fP suspicious that you are being spoofed.
If the application you are running displays a prompt before asking for
the password, it is safest to enter secure mode \fIbefore\fP the
prompt gets displayed, and to make sure that the prompt gets displayed
correctly (in the new colors), to minimize the probability of
spoofing.
You can also bring up the menu again and make sure that a check
mark appears next to the entry.
.
.PP
\fBSecure Keyboard\fP mode will be disabled automatically if your \fI\*n\fP
window becomes iconified (or otherwise unmapped), or if you start up
a reparenting window manager (that places a title bar or other decoration
around the window) while in \fBSecure Keyboard\fP mode.
(This is a
feature of the X protocol not easily overcome.)  When this happens,
the foreground and background colors will be switched back and the bell
will sound in warning.
.
.
.SH "CHARACTER CLASSES"
Clicking the left pointer button twice in rapid succession
(double-clicking) causes all characters of the same class
(e.g., letters, white space, punctuation) to be selected as a \*(``word\*(''.
Since different people have different preferences for what should
be selected (for example, should filenames be selected as a whole or only
the separate subnames), the default mapping can be overridden through the use
of the \fBcharClass\fP (class \fICharClass\fP) resource.
.
.PP
This resource is a
series of comma-separated
\fIrange\fP:\fIvalue\fP pairs.
.bP
The
\fIrange\fP is either a single number or \fIlow\fP-\fIhigh\fP in the range of 0
to 65535, corresponding to the code for the character or characters to be
set.
.bP
The \fIvalue\fP is arbitrary.  For example, the default table uses the
character number of the first character occurring in the set.
When not in
UTF-8 mode, only the first 256 entries of this table will be used.
.
.PP
The default table starts as follows \-

For example, the string \*(``33:48,37:48,45\-47:48,38:48\*('' indicates that the
exclamation mark, percent sign, dash, period, slash, and ampersand characters
should be treated the same way as characters and numbers.
This is useful
for cutting and pasting electronic mailing addresses and filenames.

.SH KEY BINDINGS
.PP
It is possible to rebind keys (or sequences of keys) to arbitrary strings
for input, by changing the \fBtranslations\fP resources
for the vt100 or tek4014 widgets.
Changing the \fBtranslations\fP resource
for events other than key and button events is not expected,
and will cause unpredictable behavior.
.SS Actions
The following
actions are provided for use within the \fIvt100\fP or \fItek4014\fP
\fBtranslations\fP resources:
.TP 8
.B "allow-bold-fonts(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowBoldFonts\fP resource and is also
invoked by the \fBallow-bold-fonts\fP entry in \fIfontMenu\fP.
.TP 8
.B "allow-color-ops(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowColorOps\fP resource and is also
invoked by the \fBallow-color-ops\fP entry in \fIfontMenu\fP.
.TP 8
.B "allow-font-ops(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowFontOps\fP resource and is also
invoked by the \fBallow-font-ops\fP entry in \fIfontMenu\fP.
.TP 8
.B "allow-mouse-ops(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowMousepOps\fP resource and is also
invoked by the \fBallow-mouse-ops\fP entry in \fIfontMenu\fP.
.TP 8
.B "allow-send-events(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowSendEvents\fP resource and is also
invoked by the \fBallowsends\fP entry in \fImainMenu\fP.
.TP 8
.B "allow-tcap-ops(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowTcapOps\fP resource and is also
invoked by the \fBallow-tcap-ops\fP entry in \fIfontMenu\fP.
.TP 8
.B "allow-title-ops(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowTitleOps\fP resource and is also
invoked by the \fBallow-title-ops\fP entry in \fIfontMenu\fP.
.TP 8
.B "allow-window-ops(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBallowWindowOps\fP resource and is also
invoked by the \fBallow-window-ops\fP entry in \fIfontMenu\fP.
.TP 8
.B "alt-sends-escape()"
This action toggles the state of the \fBaltSendsEscape\fP resource.
.TP 8
.B "bell([\fIpercent\fP])"
This action rings the keyboard bell at the specified percentage
above or below the base volume.
.TP 8
.B "clear-saved-lines()"
This action does \fBhard-reset()\fP and also clears the history
of lines saved off the top of the screen.
It is also invoked from the \fBclearsavedlines\fP entry in \fIvtMenu\fP.
The effect is identical to a hardware reset (RIS) control sequence.
.TP 8
.B "copy-selection(\fIdestname\fP [, ...])"
This action puts the currently selected text into all of the selections or
cutbuffers specified by \fIdestname\fP.
Unlike \fBselect-end\fP, it does not send a mouse position or otherwise
modify the internal selection state.
.TP 8
.B "create-menu(\fIm/v/f/t\fP)"
This action creates one of the menus used by \fI\*n\fP,
if it has not been previously created.
The parameter values are the menu names:
\fImainMenu\fP, \fIvtMenu\fP, \fIfontMenu\fP, \fItekMenu\fP, respectively.
.TP 8
.B "dabbrev-expand()"
Expands the word before cursor by searching in the preceding text on the
screen and in the scrollback buffer for words starting with that
abbreviation.
Repeating \fBdabbrev-expand()\fP several times in sequence searches for an
alternative expansion by looking farther back.
Lack of more matches is signaled by a bell.
Attempts to expand an empty word
(i.e., when cursor is preceded by a space) yield successively all previous
words.
Consecutive identical expansions are ignored.
The word here is defined as a sequence of non-whitespace characters.
This feature partially emulates the behavior
of \*(``dynamic abbreviation\*('' expansion in Emacs (bound there to M\-/).
Here is a resource setting for \fI\*n\fP which will do the same thing:
.NS
*VT100*translations:    #override \\n\\\&
        Meta  /:\fBdabbrev-expand\fP()
.NE
.TP 8
.B "deiconify()"
Changes the window state back to normal, if it was iconified.
.TP 8
.B "delete-is-del()"
This action toggles the state of the \fBdeleteIsDEL\fP resource.
.TP 8
.B "dired-button()"
Handles a button event (other than press and release)
by echoing the event's position
(i.e., character line and column) in the following format:
.sp
.in +8
^X ESC G  
.in -8
.TP 8
.B "exec-formatted(\fIformat\fP, \fIsourcename\fP [, ...])"
Execute an external command,
using the current selection for part of the command's parameters.
The first parameter, \fIformat\fP gives the basic command.
Succeeding parameters specify the selection source as in \fBinsert-selection\fP.
.IP
The \fIformat\fP parameter allows these substitutions:
.RS
.TP 5
%%
inserts a "%".
.TP 5
%P
the screen-position at the beginning of the highlighted region,
as a semicolon-separated pair of integers using the
values that the CUP control sequence would use.
.TP 5
%p
the screen-position after the beginning of the highlighted region,
using the same convention as \*(``%P\*(''.
.TP 5
%S
the length of the string that \*(``%s\*('' would insert.
.TP 5
%s
the content of the selection, unmodified.
.TP 5
%T
the length of the string that \*(``%t\*('' would insert.
.TP 5
%t
the selection, trimmed of leading/trailing whitespace.
Embedded spaces (and newlines) are copied as is.
.TP 5
%R
the length of the string that \*(``%r\*('' would insert.
.TP 5
%r
the selection, trimmed of trailing whitespace.
.TP 5
%V
the video attributes at the beginning of the highlighted region,
as a semicolon-separated list of integers using the
values that the SGR control sequence would use.
.TP 5
%v
the video attributes after the end of the highlighted region,
using the same convention as \*(``%V\*(''.
.RE
.IP
After constructing the command-string,
\fI\*n\fP forks a subprocess and executes the command,
which completes independently of \fI\*n\fP.
.IP
For example, this translation would invoke a new \fI\*n\fP process
to view a file whose name is selected while holding the shift key down.
The new process is started when the mouse button is released:
.NS
*VT100*translations: #override Shift \\
    :\fBexec-formatted\fP("xterm -e view '%t'", \fBSELECT\fP)
.NE
.TP 8
.B "exec-selectable(\fIformat\fP, \fIonClicks\fP)"
Execute an external command,
using data copied from the screen for part of the command's parameters.
The first parameter, \fIformat\fP gives
the basic command as in \fBexec-formatted\fP.
The second parameter specifies the method for copying
the data as in the \fBon2Clicks\fP resource.
.TP 8
.B "fullscreen(\fIon/off/toggle\fP)"
This action sets, unsets or toggles the \fBfullscreen\fP resource.
.TP 8
.B "iconify()"
Iconifies the window.
.TP 8
.B "hard-reset()"
This action resets the scrolling region, tabs, window size, and cursor keys
and clears the screen.
It is also invoked from the \fBhardreset\fP
entry in \fIvtMenu\fP.
.TP 8
.B "ignore()"
This action ignores the event but checks for special pointer position
escape sequences.
.TP 8
.B "insert()"
This action inserts the character or string associated with
the key that was pressed.
.TP 8
.B "insert-eight-bit()"
This action inserts an eight-bit (Meta) version of the character or string
associated with the key that was pressed.
Only single-byte values are treated specially.
The exact action depends on the value of
the \fBaltSendsEscape\fP and
the \fBmetaSendsEscape\fP and
the \fBeightBitInput\fP resources.
The \fBmetaSendsEscape\fP resource is tested first.
See the \fBeightBitInput\fP resource for a full discussion.
.IP
The term \*(``eight-bit\*('' is misleading:
\fI\*n\fP checks if the key is in the range 128 to 255
(the eighth bit is set).
If the value is in that range,
depending on the resource values,
\fI\*n\fP may then do one of the following:
.RS
.bP
add 128 to the value, setting its eighth bit,
.bP
send an ESC byte before the key, or
.bP
send the key unaltered.
.RE
.TP 8
.B "insert-formatted(\fIformat\fP, \fIsourcename\fP [, ...])"
Insert the current selection or data related to it, formatted.
The first parameter, \fIformat\fP gives the template for the data
as in \fBexec-formatted\fP.
Succeeding parameters specify the selection source as in \fBinsert-selection\fP.
.TP 8
.B "insert-selectable(\fIformat\fP, \fIonClicks\fP)"
Insert data copied from the screen, formatted.
The first parameter, \fIformat\fP gives the template for the data
as in \fBexec-formatted\fP.
The second parameter specifies the method for copying
the data as in the \fBon2Clicks\fP resource.
.TP 8
.B "insert-selection(\fIsourcename\fP [, ...])"
This action inserts the string found in the selection or cutbuffer indicated
by \fIsourcename\fP.
Sources are checked in the order given (case is
significant) until one is found.
Commonly-used selections include:
\fIPRIMARY\fP, \fISECONDARY\fP, and \fICLIPBOARD\fP.
Cut buffers are
typically named \fICUT_BUFFER0\fP through \fICUT_BUFFER7\fP.
.TP 8
.B "insert-seven-bit()"
This action is a synonym for \fBinsert()\fP.
The term \*(``seven-bit\*('' is misleading:
it only implies that \fI\*n\fP does not try to add 128 to the key's value
as in \fBinsert-eight-bit()\fP.
.TP 8
.B "interpret(\fIcontrol-sequence\fP)"
Interpret the given control sequence locally, i.e., without passing it to
the host.
This works by inserting the control sequence at the front
of the input buffer.
Use \*(``\\\*('' to escape octal digits in the string.
Xt does not allow you to put a null character (i.e., \*(``\\000\*('') in the string.
.TP 8
.B "keymap(\fIname\fP)"
This action dynamically defines a new translation table whose resource
name is \fIname\fP with the suffix \*(``\fIKeymap\fP\*(''
(i.e., \fIname\fP\fBKeymap\fP, where case is significant).
The name \fINone\fP restores the original translation table.
.TP 8
.B "larger-vt-font()"
Set the font to the next larger one, based on the font dimensions.
See also \fBset-vt-font()\fP.
.TP 8
.B "load-vt-fonts(\fIname\fP[,\fIclass\fP])"
Load fontnames from the given subresource name and class.
That is, load the \*(``*VT100.\fIname\fP.font\*('',
resource as \*(``*VT100.font\*('' etc.
If no name is given, the original set of fontnames is restored.
.IP
Unlike \fBset-vt-font()\fR, this does not affect the escape- and select-fonts,
since those are not based on resource values.
It does affect the fonts loosely organized under the \*(``Default\*('' menu
entry, including \fBfont\fP, \fBboldFont\fP, \fBwideFont\fP and \fBwideBoldFont\fP.
.TP 8
.B "maximize()"
Resizes the window to fill the screen.
.TP 8
.B "meta-sends-escape()"
This action toggles the state of the \fBmetaSendsEscape\fP resource.
.TP 8
.B "popup-menu(\fImenuname\fP)"
This action displays the specified popup menu.
Valid names (case is
significant) include:  \fImainMenu\fP, \fIvtMenu\fP, \fIfontMenu\fP,
and \fItekMenu\fP.
.TP 8
.B "print(\fIprinter-flags\fP)"
This action prints the window.
It is also invoked by the \fBprint\fP entry in \fImainMenu\fP.
.IP
The action accepts optional parameters, which temporarily override
resource settings.
The parameter values are matched ignoring case:
.RS
.TP 5
noFormFeed
no form feed will be sent at the end of the last line printed
(i.e., \fBprinterFormFeed\fP is ``false'').
.TP 5
FormFeed
a form feed will be sent at the end of the last line printed
(i.e., \fBprinterFormFeed\fP is ``true'').
.TP 5
noNewLine
no newline will be sent at the end of the last line printed,
and wrapped lines will be combined into long lines
(i.e., \fBprinterNewLine\fP is ``false'').
.TP 5
NewLine
a newline will be sent at the end of the last line printed,
and each line will be limited (by adding a newline) to the screen width
(i.e., \fBprinterNewLine\fP is ``true'').
.TP 5
noAttrs
the page is printed without attributes
(i.e., \fBprintAttributes\fP is ``0'').
.TP 5
monoAttrs
the page is printed with monochrome (vt220) attributes
(i.e., \fBprintAttributes\fP is ``1'').
.TP 5
colorAttrs
the page is printed with ANSI color attributes
(i.e., \fBprintAttributes\fP is ``2'').
.RE
.TP 8
.B "print-everything(\fIprinter-flags\fP)"
This action sends the entire text history, in addition to the text
currently visible, to the program given in the \fBprinterCommand\fP resource.
It allows the same optional parameters as the \fBprint\fP action.

history in an editor.
.TP 8
.B "print-immediate()"
Sends the text of the current window directly to a file,
as specified by the
\fBprintFileImmediate\fP,
\fBprintModeImmediate\fP and
\fBprintOptsImmediate\fP
resources.

Toggles a flag telling \fI\*n\fP that if it exits with an X error,
to send the text of the current window directly to a file,
as specified by the
\fBprintFileOnXError\fP,
\fBprintModeOnXError\fP and
\fBprintOptsOnXError\fP
resources.
.TP 8
.B "print-redir()"
This action toggles the \fBprinterControlMode\fR between 0 and 2.
The corresponding popup menu entry is useful for switching the printer
off if you happen to change your mind after deciding to print random
binary files on the terminal.
.TP 8
.B "quit()"
.br
This action sends a SIGHUP to the subprogram and exits.
It is also invoked
by the \fBquit\fP entry in \fImainMenu\fP.
.TP 8
.B "readline-button()"
Supports the optional readline feature by echoing repeated cursor forward
or backward control sequences on button release event,
to request that the host application update its notion of the cursor's
position to match the button event.
.TP 8
.B "redraw()"
This action redraws the window.
It is also invoked by the \fBredraw\fP entry in \fImainMenu\fP.
.TP 8
.B "restore()"
Restores the window to the size before it was last maximized.
.TP 8
.B "scroll-back(\fIcount\fP [,\fIunits\fP [,\fImouse\fP] ])"
This action scrolls the text window backward so that text that had previously
scrolled off the top of the screen is now visible.
.IP
The \fIcount\fP argument
indicates the number of \fIunits\fP (which may be \fIpage\fP, \fIhalfpage\fP,
\fIpixel\fP, or \fIline\fP) by which to scroll.
.IP
An adjustment can be specified for these values
by appending a \*(``+\*('' or \*(``\-\*(''
sign followed by a number,
e.g., \fIpage\-2\fP to specify 2 lines less than a page.
.IP
If the third parameter \fImouse\fP is given, the action is ignored when
mouse reporting is enabled.
.TP 8
.B "scroll-forw(\fIcount\fP [,\fIunits\fP [,\fImouse\fP] ])"
This action is similar to \fBscroll-back\fP except that it scrolls
in the other direction.

You can modify the \fBtranslations\fP resource by overriding parts
of it, or merging your resources with it.
.PP
Here is an example which uses shifted select/paste to copy to the clipboard,
and unshifted select/paste for the primary selection.
In each case, a (different) cut buffer is
also a target or source of the select/paste operation.
It is important to remember however,
that cut buffers store data in ISO-8859-1 encoding,
while selections can store data in a variety of formats and encodings.
While \fI\*n\fP owns the selection, it highlights it.
When it loses the selection, it removes the corresponding highlight.
But you can still paste from the corresponding cut buffer.

    Shift      : \fBselect-end\fP(\fBCLIPBOARD\fP, CUT_BUFFER1)
.NE
.PP
In the example, the class name \fBVT100\fP is used rather than the widget name.
These are different; a class name could apply to more than one widget.
A leading \*(``*\*('' is used because the widget hierarchy above the
\fIvt100\fP widget depends on
whether the toolbar support is compiled into \fI\*n\fP.
.PP
Not everyone finds the three-button mouse bindings easy to use.
In a wheel mouse, the middle button might be the wheel.
As an alternative, you could add a binding shifted keys:
.NS
*VT100*translations:      #override \\n\\
    Shift Home:    \fBcopy-selection\fP(\fBSELECT\fP) \\n\\
    Shift Insert:  \fBcopy-selection\fP(\fBSELECT\fP) \\n\\
    Ctrl Shift C:  \fBcopy-selection\fP(\fBSELECT\fP) \\n\\
    Ctrl Shift V:  \fBinsert-selection\fP(\fBSELECT\fP)
.NE
.PP
You would still use the left- and right-mouse buttons (typically 1 and 3)
for beginning and extending selections. 
.PP
Besides mouse problems, there are also keyboards with inconvenient layouts.
Some lack a numeric keypad, making it hard to use the shifted keypad plus
and minus bindings for switching between font sizes.
You can work around that by assigning the actions to more readily accessed
keys:
.NS
*VT100*translations:      #override \\n\\
    Ctrl  +:       \fBlarger-vt-font\fP() \\n\\
    Ctrl  -:       \fBsmaller-vt-font\fP()
.NE

The keymap feature allows you to switch between sets of translations.

how the \fBkeymap()\fP action may be used to add special

.SS Default Scrollbar Bindings
.PP
Key bindings are normally associated with the \fIvt100\fP or \fItek4014\fP
widgets which act as terminal emulators.
\fI\*N\fP's scrollbar (and toolbar if it is configured) are separate widgets.
Because all of these use the X Toolkit,
they have corresponding \fBtranslations\fP resources.
Those resources are distinct,
and match different patterns, e.g., the differences in widget-name and
number of levels of widgets which they may contain.
.PP
The \fIscrollbar\fP widget is a child of the \fIvt100\fP widget.
It is positioned on top of the \fIvt100\fP widget.
Toggling the scrollbar on and off causes the \fIvt100\fP widget to resize.
.PP
The default bindings for the scrollbar widget use only mouse-button events:
.NS
   : StartScroll(Forward) \\n\\\&
   : StartScroll(Forward) \\n\\\&
   : StartScroll(Continuous) MoveThumb() NotifyThumb() \\n\\\&
   : StartScroll(Backward) \\n\\\&
   : StartScroll(Backward) \\n\\\&
   : MoveThumb() NotifyThumb() \\n\\\&
   :    NotifyScroll(Proportional) EndScroll()
.NE
.PP
Events which the \fIscrollbar\fP widget does not recognize at all are lost.
.PP
However, at startup, \fI\*n\fP augments these translations with the default
translations used for the \fIvt100\fP widget,
together with the resource \*(``actions\*('' which those translations use.
Because the \fIscrollbar\fP (or \fImenubar\fP) widgets do not recognize these
actions (but because it has a corresponding translation),
they are passed on to the \fIvt100\fP widget.
.PP
This augmenting of the scrollbar's translations has a few limitations:
.bP
\fI\*N\fP knows what the default translations are,
but there is no suitable library interface for determining what
customizations a user may have added to the \fIvt100\fP widget.
All that \fI\*n\fP can do is augment the \fIscrollbar\fP widget to
give it the same starting point for further customization by the user.
.bP
Events in the gap between the widgets may be lost.
.bP
Compose sequences begun in one widget cannot be completed in the other,
because the input methods for each widget do not share context information.
.PP
Most customizations of the scrollbar translations do not concern key bindings.
Rather, users are generally more interested in changing the bindings of the
mouse buttons.
For example, some people prefer using the left pointer button
for dragging the scrollbar thumb.
That can be set up by altering the translations resource, e.g.,
.NS
*VT100.scrollbar.translations:  #override \\n\\\&
   :     StartScroll(Forward) \\n\\\&
   :     StartScroll(Continuous) MoveThumb() NotifyThumb() \\n\\\&

   :   MoveThumb() NotifyThumb() \\n\\\&
   :        NotifyScroll(Proportional) EndScroll()

.SH "CONTROL SEQUENCES AND KEYBOARD"
Applications can send sequences of characters to the terminal to change its
behavior.
Often they are referred to as
\*(``ANSI escape sequences\*('' or just plain
\*(``escape sequences\*('' but both terms are misleading:
.bP
ANSI x3.64 (obsolete) which was replaced by ISO 6429 (ECMA-48) gave rules
for the \fIformat\fP of these sequences of characters.
.bP
While the original VT100 was claimed to be ANSI-compatible (against x3.64),
there is no freely available version of the ANSI standard to show where
the VT100 differs.
Most of the documents which mention the ANSI standard have
additions not found in the original (such as those
based on \fBansi.sys\fP).
So this discussion focuses on the ISO standards.
.bP
The standard describes only sequences sent from the host to the terminal.
There is no standard for sequences sent by special keys from the terminal
to the host.
By convention (and referring to existing terminals), the format of those
sequences usually conforms to the host-to-terminal standard.
.bP
Some of \fI\*n\fP's sequences do not fit into the standard scheme.
Technically those are \*(``unspecified\*(''.
As an example,
DEC Screen Alignment Test (DECALN) is this three-character sequence:
.NS
\fIESC\fP # 8
.NE
.PP
.bP
Some sequences fit into the standard format,
but are not listed in the standard.
These include the sequences used for setting up scrolling margins
and doing forward/reverse scrolling.
.bP
Some of the sequences (in particular, the single-character functions
such as tab and backspace)
do not include the \fIescape\fP character.
.PP
With all of that in mind, the standard refers to these sequences of
characters as \*(``control sequences\*(''.
.PP
\fI\*N Control Sequences\fP lists the control sequences which
an application can send \fI\*n\fP to make it perform various operations.
Most of these operations are standardized, from either the DEC or Tektronix
terminals, or from more widely used standards such as ISO-6429.
.PP
A few examples of usage are given in this section.
.SS Window and Icon Titles
.PP
Some scripts use \fBecho\fP with options \fB\-e\fP and \fB\-n\fP to tell
the shell to interpret the string \*(``\\e\*('' as the \fIescape\fP character and
to suppress a trailing newline on output.
Those are not portable, not recommended.
Instead, use \fBprintf\fP (POSIX).
.PP
For example, to set the \fIwindow title\fP to \*(``Hello world!\*('',
you could use one of these commands in a script:
.NS
printf '\\033]2;Hello world!\\033\\'
printf '\\033]2;Hello world!\\007'
printf '\\033]2;%s\\033\\' "Hello world!"
printf '\\033]2;%s\\007' "Hello world!"
.NE
.PP
The \fBprintf\fP command interprets the octal value \*(``\\033\*('' for
\fIescape\fP, and (since it was not given in the format) omits a trailing
newline from the output.
.PP
Some programs (such as \fBscreen\fP(1)) set both window- and icon-titles
at the same time, using a slightly different control sequence:
.NS
printf '\\033]0;Hello world!\\033\\'
printf '\\033]0;Hello world!\\007'
printf '\\033]0;%s\\033\\' "Hello world!"
printf '\\033]0;%s\\007' "Hello world!"
.NE
.PP
The difference is the \fIparameter\fP \*(``0\*('' in each command.
Most window managers will honor either window title or icon title.
Some will make a distinction and allow you to set just the icon title.
You can tell \fI\*n\fP to ask for this with a different parameter
in the control sequence:
.NS
printf '\\033]1;Hello world!\\033\\'
printf '\\033]1;Hello world!\\007'
printf '\\033]1;%s\\033\\' "Hello world!"
printf '\\033]1;%s\\007' "Hello world!"

has two modes for the \fIspecial keys\fP (cursor-keys, numeric keypad,
and certain function-keys):
.bP
\fInormal mode\fP, which makes the special keys transmit 
\*(``useful\*('' sequences such as the control sequence for cursor-up
when pressing the up-arrow, and
.bP
\fIapplication mode\fP,
which uses a different control sequence that cannot be mistaken for
the 
\*(``useful\*('' sequences.
.PP
The main difference between the two modes is that normal mode sequences
start with \fICSI\fP (\fIescape\ [\fP) and application mode sequences
start with \fISS3\fP (\fIescape\ O\fP).
.PP
The terminal is initialized into one of these two modes (usually the
normal mode), based on the terminal description (termcap or terminfo).
The terminal description also has capabilities (strings) defined for
the keypad mode used in curses applications.
.PP
There is a problem in using the terminal description for applications
that are not intended to be full-screen curses applications:
the definitions of special keys are only correct for this keypad mode.
For example, some shells
(unlike \fBksh\fP(1), which appears to be hard-coded, not even using termcap)
allow their users to customize key-bindings,
assigning shell actions to special keys.
.bP
\fBbash\fP(1) allows \fIconstant\fP strings to be assigned
to functions.
This is only successful if the terminal is initialized to application
mode by default,
because \fBbash\fP lacks flexibility in this area.
It uses a (less expressive than \fBbash\fP's)
\fBreadline\fP scripting language for setting up key bindings,
which relies upon the user to statically enumerate the possible bindings for
given values of \fB$TERM\fP.
.bP
\fBzsh\fP(1) provides an analogous feature,
but it accepts runtime expressions,
as well as providing a \fB$terminfo\fP array for scripts.
In particular, one can use the terminal database,
transforming when defining a key-binding.
By transforming the output so that \fICSI\fP and \fISS3\fP are equated,
\fBzsh\fP can use the terminal database to obtain useful definitions
for its command-line use regardless of whether the terminal uses
normal or application mode initially.
Here is an example:
.NS
[[ "$terminfo[kcuu1]" == "^[O"* ]] && \\
bindkey -M viins "${terminfo[kcuu1]/O/[}" \\
vi-up-line-or-history
.NE
.
.
.SS Changing Colors
.PP
A few shell programs provide the ability for users to add color and other
video attributes to the shell prompt strings.
Users can do this by setting \fB$PS1\fP (the primary prompt string).
Again, \fBbash\fP and \fBzsh\fP have provided features not found in \fBksh\fP.
There is a problem, however: the prompt's width on the screen will not
necessarily be the same as the number of characters.
Because there is no guidance in the POSIX standard, each shell addresses
the problem in a different way:
.bP
\fBbash\fP treats characters within 
\*(``\\[\*('' and
\*(``\\]\*(''
as nonprinting (using no width on the screen).
.bP
\fBzsh\fP treats characters within 
\*(``%{\*('' and
\*(``%}\*(''
as nonprinting.
.PP
In addition to the difference in syntax,
the shells provide different methods for obtaining useful escape sequences:
.bP
As noted in \fBSpecial Keys\fP, \fBzsh\fP initializes the $terminfo array
with the terminal capabilities.
.IP
It also provides a function \fBechoti\fP which works like \fBtput\fP(1)
to convert a terminal capability with its parameters into a string
that can be written to the terminal.
.bP
Shells lacking a comparable feature (such as \fBbash\fP) can always
use the program \fBtput\fP to do this transformation.
.PP
Hard-coded escape sequences are supported by each shell,
but are not recommended because those rely upon particular configurations
and cannot be easily moved between different user environments.
.
.
.SH ENVIRONMENT
\fI\*N\fP sets several environment variables.
.SS System Independent
.PP
Some variables are used on every system:
.TP 5
.B DISPLAY
is the display name,
pointing to the X server (see \fIDISPLAY NAMES\fP in X(__miscmansuffix__)).
.TP 5
.B TERM
.br
is set according to the terminfo (or termcap) entry which it is using as
a reference.
.IP
On some systems, you may encounter situations where the shell which you
use and \fI\*n\fP are built using libraries with different terminal databases.
In that situation, \fI\*n\fP may choose a terminal description not known
to the shell.
.TP 5
.B WINDOWID
is set to the X window id number of the \fI\*n\fP window.
.TP 5
.B XTERM_FILTER
is set if a locale-filter is used.
The value is the pathname of the filter.
.TP 5
.B XTERM_LOCALE
shows the locale which was used by \fI\*n\fP on startup.
Some shell initialization scripts may set a different locale.
.TP 5
.B XTERM_SHELL
is set to the pathname of the program which is invoked.
Usually that is a shell program, e.g., \fI/bin/sh\fP.
Since it is not necessarily a shell program however,
it is distinct from \*(``SHELL\*(''.
.TP 5
.B XTERM_VERSION
is set to the string displayed by the \fB\-version\fP option.
That is normally an identifier for the X Window libraries used to
build \fI\*n\fP, followed by
\fI\*n\fP's patch number in parenthesis.
The patch number is also part of the response to a Secondary Device Attributes
(DA) control sequence (see \fIXterm Control Sequences\fP).
.
.SS System Dependent
.
.PP
Depending on your system configuration, \fI\*n\fP may also set the
following:
.TP 5
.B COLUMNS
the width of the \fI\*n\fP in characters (cf: \*(``stty columns\*('').
.IP
When this variable is set, \fIcurses\fP applications (and most
terminal programs) will assume that the terminal has this many columns.
.IP
\fI\*N\fP would do this for systems which have no ability
to tell the size of the terminal.
Those are very rare, none newer than the mid 1990s when SVR4 became prevalent.
.TP 5
.B HOME
.br
when \fI\*n\fP is configured (at build-time) to update utmp.
.TP 5
.B LINES
the height of the \fI\*n\fP in characters (cf: \*(``stty rows\*('').
.IP
When this variable is set, \fIcurses\fP applications (and most
terminal programs) will assume that the terminal has this many lines (rows).
.IP
\fI\*N\fP would do this for systems which have no ability
to tell the size of the terminal.
Those are very rare, none newer than the mid 1990s when SVR4 became prevalent.
.TP 5
.B LOGNAME
when \fI\*n\fP is configured (at build-time) to update utmp.
.IP
Your configuration may have set \fBLOGNAME\fP; \fI\*n\fP does not modify that.
If it is unset, \fI\*n\fP will use \fBUSER\fP if it is set.
Finally, if neither is set, \fI\*n\fP will use the \fBgetlogin\fP(2) function.
.TP 5
.B SHELL
when \fI\*n\fP is configured (at build-time) to update utmp.
It is also set if you provide a valid shell name as the optional parameter.
.IP
\fI\*N\fP sets this to an absolute pathname.
If you have set the variable to a relative pathname,
\fI\*n\fP may set it to a different shell pathname.
.IP
If you have set this to an pathname which does not correspond to a valid
shell, \fI\*n\fP may unset it, to avoid confusion.
.TP 5
.B TERMCAP
the contents of the termcap entry corresponding to \fB$TERM\fP,
with lines and columns values substituted
for the actual size window you have created.
.IP
This feature is, like \fBLINES\fP and \fBCOLUMNS\fP, used rarely.
It addresses the same limitation of a few older systems
by providing a way for \fItermcap\fP-based applications to get the initial
screensize.
.TP 5
.B TERMINFO
may be defined to a nonstandard location using the configure script.
.\"
.
.
.SH FILES
The actual pathnames given may differ on your system.
.TP 5
\fI/etc/shells\fP
contains a list of valid shell programs,
used by \fI\*n\fP to decide if the \*(``SHELL\*('' environment
variable should be set for the process started by \fI\*n\fP.
.TP 5
\fI/etc/utmp\fP
the system logfile, which records user logins.
.TP 5
\fI/etc/wtmp\fP
the system logfile, which records user logins and logouts.
.TP 5
.I __apploaddir__/__default_class__
the \fI\*n\fP default application resources.
.TP 5
.I __apploaddir__/__default_class__\-color
the \fI\*n\fP color application resources.
If your display supports color, use this
.in +10
*customization: \-color
.in -10
in your .Xdefaults file to
automatically use this resource file rather than
.IR __apploaddir__/__default_class__ .
If you do not do this,
\fI\*n\fP uses its compiled-in default resource settings for colors.
.TP 5
.I __pixmapsdir__
the directory in which \fI\*n\fP's pixmap icon files are installed.
.
.
.SH ERROR MESSAGES
Most of the fatal error messages from \fI\*n\fP use the following format:
.NS
\*n: Error \fIXXX\fP, errno \fIYYY\fP: \fIZZZ\fR
.NE
.PP
The \fIXXX\fP codes (which are used by \fI\*n\fP as its exit-code)

.SH BUGS
.
.PP
Large pastes do not work on some systems.
This is not a bug in
\fI\*n\fP; it is a bug in the pseudo terminal driver of those
systems.
\fI\*N\fP feeds large pastes to the pty only as fast as the pty
will accept data, but some pty drivers do not return enough information
to know if the write has succeeded.
.
.PP
When connected to an input method, it is possible for \*n to hang
if the XIM server is suspended or killed.
.
.PP
Many of the options are not resettable after
.I \*n
starts.
.
.PP
This program still needs to be rewritten.
It should be split into very
modular sections, with the various emulators being completely separate
widgets that do not know about each other.
Ideally, you'd like to be able to
pick and choose emulator widgets and stick them into a single control widget.
.
.PP
There needs to be a dialog box to allow entry of the Tek COPY file name.

 * According to
 * http://www.unix.com/man-page/all/3x/XAllocColoA/
 *
 *     XAllocColor() acts differently on static and dynamic visuals.  On Pseu-
 *     doColor, DirectColor, and GrayScale  visuals,  XAllocColor()  fails  if
 *     there  are  no  unallocated  colorcells and no allocated read-only cell
 *     exactly matches the requested RGB values.  On  StaticColor,  TrueColor,
 *     and  StaticGray  visuals,  XAllocColor() returns the closest RGB values
 *     available in the colormap.  The colorcell_in_out structure returns  the
 *     actual RGB values allocated.
 *
 * That is, XAllocColor() should suffice unless the color map is full.  In that
 * case, allocateClosestRGB() is useful for the dynamic display classes such as
 * PseudoColor.  It is not useful for TrueColor, since XQueryColors() does not
 * return regular RGB triples (unless a different scheme was used for
 * specifying the pixel values); only the blue value is filled in.  However, it
 * is filled in with the colors that the server supports.
 *
 * Also (the reason for this function), XAllocColor() does not really work as
 * described.  For some TrueColor configurations it merely returns a close
 * approximation, but not the closest.

 * This module converts keysym values into the corresponding ISO 10646
 * (UCS, Unicode) values.
 *
 * The array keysymtab[] contains pairs of X11 keysym values for graphical
 * characters and the corresponding Unicode value. The function
 * keysym2ucs() maps a keysym onto a Unicode value using a binary search,
 * therefore keysymtab[] must remain SORTED by keysym value.
 *
 * The keysym -> UTF-8 conversion will hopefully one day be provided
 * by Xlib via XmbLookupString() and should ideally not have to be
 * done in X applications. But we are not there yet.
 *
 * We allow to represent any UCS character in the range U-00000000 to
 * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
 * This admittedly does not cover the entire 31-bit space of UCS, but
 * it does cover all of the characters up to U-10FFFF, which can be
 * represented by UTF-16, and more, and it is very unlikely that higher
 * UCS codes will ever be assigned by ISO. So to get Unicode character
 * U+ABCD you can directly use keysym 0x0100abcd.
 *
 * NOTE: The comments in the table below contain the actual character
 * encoded in UTF-8, so for viewing and editing best use an editor in
 * UTF-8 mode.
 *
 * Author: Markus G. Kuhn , University of Cambridge, April 2001
 *
 * Special thanks to Richard Verhoeven  for preparing
 * an initial draft of the mapping table.

/*
 * graphics TODO list
 *
 * ReGIS:
 * - ship a default alphabet zero font instead of scaling Xft fonts
 * - input cursors
 * - output cursors
 * - mouse/tablet/arrow-key input
 * - fix graphic pages for ReGIS -- they should also apply to text and sixel graphics
 * - fix interpolated curves to more closely match implementation (identical despite direction and starting point)
 * - non-ASCII alphabets
 * - enter/leave anywhere in a command
 * - locator key definitions (DECLKD)
 * - command display mode
 * - re-rasterization on window resize
 * - macros
 * - improved fills for narrow angles (track actual lines not just pixels)
 * - hardcopy/screen-capture support (need dialog of some sort for safety)
 * - error reporting
 *
 * sixel:
 * - fix problem where new_row < 0 during sixel parsing (see FIXME)
 * - screen-capture support (need dialog of some sort for safety)
 *
 * VT55/VT105 waveform graphics
 * - everything
 *
 * Tektronix:
 * - color (VT340 4014 emulation, 41xx, IRAF GTERM, and also MS-DOS Kermit color support)
 * - polygon fill (41xx)
 * - clear area extension
 * - area fill extension
 * - pixel operations (RU/RS/RP)
 * - research other 41xx and 42xx extensions
 *
 * common graphics features:
 * - handle light/dark screen modes (CSI?5[hl])
 * - update text fg/bg color which overlaps images
 * - handle graphic updates in scroll regions (verify effect on graphics)
 * - handle rectangular area copies (verify they work with graphics)
 * - invalidate graphics under graphic if same origin, at least as big, and bg not transparent
 * - invalidate graphic if completely scrolled past end of scrollback
 * - invalidate graphic if all pixels are transparent/erased
 * - invalidate graphic if completely scrolled out of alt buffer
 * - posturize requested colors to match hardware palettes (e.g. only four possible shades on VT240)
 * - color register report/restore
 * - ability to select/copy graphics for pasting in other programs
 * - ability to show non-scroll-mode sixel graphics in a separate window
 * - ability to show ReGIS graphics in a separate window
 * - ability to show Tektronix graphics in VT100 window
 * - truncate graphics at bottom edge of terminal?
 * - locator events (DECEFR DECSLE DECELR DECLRP)
 * - locator controller mode (CSI6i / CSI7i)
 *
 * new escape sequences:
 * - way to query text font size without "window ops" (or make "window ops" permissions more fine grained)
 * - way to query and set the number of graphics pages
 *
 * ReGIS extensions:
 * - non-integer text scaling
 * - free distortionless text rotation (vs. simulating the distortion and aligning to 45deg increments)
 * - font characteristics: bold/underline/italic
 * - remove/increase arbitrary limits (pattern size, pages, alphabets, stack size, font names, etc.)
 * - shade/fill with borders
 * - sprites (copy portion of page into/out of buffer with scaling and rotation)
 * - ellipses
 * - 2D patterns
 * - option to set actual graphic size (not just coordinate range)
 * - gradients (for lines and fills)
 * - line width (RLogin has this and it is mentioned in docs for the DEC ReGIS to Postscript converter)
 * - transparency
 * - background color as stackable write control
 * - true color (virtual color registers created upon lookup)
 * - anti-aliasing
 * - variable-width (proportional) text

The literal character \fIc\fP.
.IP \*(Cc
A single (required) character.
.IP \*(Ps
A single (usually optional) numeric parameter, composed of one of more digits.
.IP \*(Pm
A multiple numeric parameter composed of any number of single numeric
parameters, separated by \*; character(s).
Individual values for the parameters are listed with \*(Ps .
.IP \*(Pt
A text parameter composed of printable characters.

.Sh "Control Bytes, Characters, and Sequences"
.LP
ECMA-48 (aka "ISO 6429") documents C1 (8-bit) and C0 (7-bit) codes.
Those are respectively codes 128 to 159 and 0 to 31.
ECMA-48 avoids referring to these codes as characters,
because that term is associated with \fIgraphic characters\fP.
Instead, it uses \*(``bytes\*('' and \*(``codes\*('',
with occasional lapses to \*(``characters\*(''
where the meaning cannot be mistaken.
.LP
Controls (including the escape code 27) are processed once:
.bP
This means that a C1 control can be mistaken for badly-formed UTF-8
when the terminal runs
in UTF-8 mode because C1 controls are valid \fIcontinuation bytes\fP of
a UTF-8 encoded (multibyte) value.
.bP
It is not possible to use a C1 control obtained from decoding the UTF-8 text,
because that would require reprocessing the data.
Consequently there is no ambiguity in the way
this document uses the term \*(``character\*('' to refer to
bytes in a control sequence.
.LP
The order of processing is a necessary consequence of the way ECMA-48
is designed:
.bP
Each byte sent to the terminal can be unambiguously determined to
fall into one of a few categories (C0, C1 and graphic characters).
.bP
ECMA-48 is \fImodal\fP; once it starts processing a control sequence,
the terminal continues until the sequence is complete,
or some byte is found which is not allowed in the sequence.
.bP
Intermediate, parameter and final bytes may
use the same codes as graphic characters,
but they are processed as part of a control sequence and are not actually
graphic characters.
.bP
Eight-bit controls can have intermediate, etc., bytes in the range 160 to 255.
Those can be treated as their counterparts in the range 32 to 127.
.bP
Single-byte controls can be handled separately from multi-byte
control sequences because ECMA-48's rules are unambiguous.
.IP
As a special case, ECMA-48 (section 9) mentions that the control functions
shift-in and shift-out are allowed to occur within a 7-bit multibyte control
sequence because those cannot alter the meaning of the control sequence.
.bP
Some controls (such as \*(Os) introduce a string mode,
which is ended on a \*(ST (string terminator).
.IP
Again, the terminal should accept single-byte controls within the string.
However, \fIxterm\fP has a resource setting \fBbrokenLinuxOSC\fP to allow
recovery from applications which rely upon malformed palette sequences
used by the Linux console.
.
.Sh "C1 (8-Bit) Control Characters"
.LP
The \fIxterm\fP program recognizes both 8-bit and 7-bit control characters.
It generates 7-bit controls (by default) or 8-bit if S8C1T is enabled.
The following pairs of 7-bit and 8-bit control characters are equivalent:

.LP
These control characters are used in the vtXXX emulation.
.
.Sh "VT100 Mode"
.LP
Most of these control sequences are standard VT102 control sequences,
but there is support for later DEC VT terminals
(i.e., VT220, VT320, VT420, VT510),
as well as ISO 6429 and \fIaixterm\fP color controls.
The only VT102 feature not supported is auto-repeat,
since the only way X provides for this will affect all windows.
.LP
There are additional control sequences to provide
\fIxterm-\fPdependent functions, such as the scrollbar or window size.
Where the function is specified by DEC or ISO 6429, the code assigned
to it is given in parentheses.
.LP
The escape codes to designate and invoke
character sets are specified by ISO 2022 (see that document for a
discussion of character sets).
.LP
Many of the features are optional;
\fI\*(xt\fP can be configured and built without support for them.

\fBNotes\fP:
.RS
.bP
The current implementation allows reading the graphics sizes,
but disallows modifying those sizes because that is done once,
using resource-values.
.bP
Graphics geometry is not necessarily the same as "window
size" (see the dtterm window manipulation extensions). For example,
\fIxterm\fP limits the maximum graphics geometry at compile time
(1000x1000 as of version 328)
although the window size can be larger.
.bP
While resizing a window will always change the current
graphics geometry, the reverse is not true.
Setting graphics geometry does not affect the window size.

.Sh "Alt and Meta Keys"
.LP
Many keyboards have keys labeled "Alt".
Few have keys labeled "Meta".
However, \fIxterm\fP's default translations use the \fIMeta\fP modifier.
Common keyboard configurations assign the \fIMeta\fP modifier to an "Alt" key.
By using \fIxmodmap\fP one may have the modifier assigned to a different key,
and have "real" alt and meta keys.
Here is an example:
.ID
.ft CW
! put meta on mod3 to distinguish it from alt
keycode 64 = Alt_L
clear mod1
add mod1 = Alt_L
keycode 115 = Meta_L
clear mod3
add mod3 = Meta_L
.ft 1
.DE
.lP
The \fBmetaSendsEscape\fP resource
(and \fBaltSendsEscape\fP if \fBaltIsNotMeta\fP is set)
can be used to control the way the \fIMeta\fP modifier applies to ordinary
keys unless the \fBmodifyOtherKeys\fP resource is set:
.IP
-
prefix a key with the \*(Es character.
.IP
-
shift the key from codes 0-127 to 128-255 by adding 128.
.lP
The table shows the result for a given character "x" with modifiers
according to the default translations with the resources set on or off.
This assumes \fBaltIsNotMeta\fP is set:

.Sh "Sun-Style Function Keys"
.LP
The \fIxterm\fP program provides support for Sun keyboards more directly, by
a menu toggle that causes it to send Sun-style function key codes rather than VT220.
Note, however, that the \fIsun\fP and \fIVT100\fP emulations are not really
compatible.
For example, their wrap-margin behavior differs.
.lP
Only function keys are altered; keypad and cursor keys are the same.
The emulation responds identically.
See the xterm-sun terminfo entry for details.
.Sh "HP-Style Function Keys"
.LP
Similarly, \fIxterm\fP can be compiled to support HP keyboards.
See the xterm-hp terminfo entry for details.
.Sh "The Alternate Screen Buffer"
.LP
\fIXterm\fP maintains two screen buffers.
The normal screen buffer allows you to scroll back to view saved lines
of output up to the maximum set by the \fBsaveLines\fP resource.
The alternate screen buffer is exactly as large as the display,
contains no additional saved lines.
When the alternate screen buffer is active,
you cannot scroll back to view saved lines.
\fIXterm\fP provides control sequences and menu entries
for switching between the two.
.lP
Most full-screen applications use terminfo or termcap to obtain
strings used to start/stop full-screen mode,
i.e., \fIsmcup\fP and \fIrmcup\fP for terminfo,
or the corresponding \fIti\fP and \fIte\fP for termcap.
The \fBtiteInhibit\fP resource removes the \fIti\fP and \fIte\fP strings
from the TERMCAP string which is set in the environment for some platforms.
That is not done when \fIxterm\fP is built with terminfo libraries because
terminfo does not provide the whole text of the termcap data in one piece.
It would not work for terminfo anyway, since terminfo data is not passed
in environment variables;
setting an environment variable in this manner would have no effect on
the application's ability to switch between normal and alternate screen
buffers.
Instead, the newer private mode controls
(such as \*1\*0\*4\*9)
for switching between normal
and alternate screen buffers simply disable the switching.
They add other features such as clearing the display for the same reason:
to make the details of switching independent of the application that
requests the switch.
.
.Sh "Bracketed Paste Mode"
.LP
When bracketed paste mode is set,
pasted text is bracketed with control sequences
so that the program can differentiate pasted text from typed-in text.
When bracketed paste mode is set,
the program will receive:
   \*(Es\*([[\*2\*0\*0\*~,
.br
followed by the pasted text, followed by
   \*(Es\*([[\*2\*0\*1\*~.
.
.Sh "Title Modes"
.LP
The window- and icon-labels can be set or queried using control sequences.
As a VT220-emulator, \fIxterm\fP "should" limit the character encoding for
the corresponding strings to ISO-8859-1.
Indeed, it used to be the case (and was documented) that
window titles had to be ISO-8859-1.
This is no longer the case.
However, there are many applications which still assume that titles are
set using ISO-8859-1.
So that is the default behavior.
.lP
If \fIxterm\fP is running with UTF-8 encoding,
it is possible to use window- and icon-labels encoded using UTF-8.
That is because the underlying X libraries (and many, but not all)
window managers support this feature.
.lP
The \fButf8Title\fP X resource setting tells \fIxterm\fP to disable
a reconversion of the title string back to ISO-8859-1,
allowing the title strings to be interpreted as UTF-8.
The same feature can be enabled using the title mode control sequence
described in this summary.
.lP
Separate from the ability to set the titles,
\fIxterm\fP provides the ability to query the titles,
returning them either in ISO-8859-1 or UTF-8.
This choice is available only while \fIxterm\fP is using UTF-8 encoding.
.lP
Finally, the characters sent to, or returned by a title control
are less constrained than the rest of the control sequences.
To make them more manageable (and constrained), for use in shell scripts,
\fIxterm\fP has an optional feature which decodes the string from hexadecimal
(for setting titles) or for encoding the title into hexadecimal when querying
the value.
.
.Sh "Mouse Tracking"
.LP
The VT widget can be set to send the mouse position and other
information on button presses.
These modes are typically used by
editors and other full-screen applications that want to make use of
the mouse.
.lP
There are two sets of mutually exclusive modes:
.bP
mouse protocol
.bP
protocol encoding
.lP
The mouse protocols include
DEC Locator mode, enabled by the
DECELR \*(Cs\*(Ps\*s\*;\*(Ps\*s\*s\*(qu\*s\*z
control sequence, and is not described here
(control sequences are summarized above).
The remaining five modes of the mouse protocols
are each enabled (or disabled) by a different parameter in
the "DECSET \*(Cs\*?\*(Pm\*s\*h"
or
"DECRST \*(Cs\*?\*(Pm\*s\*l"
control sequence.
.lP
Manifest constants for the parameter values
are defined in \fBxcharmouse.h\fP as follows:
.

.br
The motion reporting modes are strictly \fIxterm\fP extensions, and are not
part of any standard, though they are analogous to the DEC VT200 DECELR
locator reports.
.lP
Normally,
parameters (such as pointer position and button number) for all mouse
tracking escape sequences generated by \fIxterm\fP
encode numeric parameters in a single character as
\fIvalue\fP+32.
For example, \*! specifies the value 1.
The upper left character position on the terminal is denoted as 1,1.
This scheme dates back to X10,
though the normal mouse-tracking (from X11) is more elaborate.
.Ss X10 compatbility mode
.lP
X10 compatibility mode sends an escape sequence only on button press,
encoding the location and the mouse button pressed.
It is enabled by specifying parameter 9 to DECSET.
On button press, \fIxterm\fP sends
\*(Cs\*M\*(Cb\*(Cx\*(Cy (6 characters).
.bP
\*(Cb is button\-1.
.bP
\*(Cx and \*(Cy are the x and y coordinates of the mouse when the
button was pressed.
.Ss Normal tracking mode
.lP
Normal tracking mode sends an escape sequence on both button press and
release.
Modifier key (shift, ctrl, meta) information is also sent.
It is enabled by specifying parameter 1000 to DECSET.
On button press or release, \fIxterm\fP sends
\*(Cs\*M\*(Cb\*(Cx\*(Cy.
.bP
The low two bits of \*(Cb encode button information:
0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.
.bP
The next three bits encode the modifiers which were down when the button was
pressed and are added together:  4=Shift, 8=Meta, 16=Control.
Note however that the shift and control bits are normally unavailable
because \fIxterm\fP uses the control modifier with mouse for popup menus,
and the shift modifier is used in the default translations for button events.
The \fIMeta\fP modifier recognized by \fIxterm\fP is the \fImod1\fP mask,
and is not necessarily the "Meta" key (see \fIxmodmap\fP).
.bP
\*(Cx and \*(Cy are the x and y coordinates of the mouse event, encoded as
in X10 mode.
.Ss Wheel mice
.lP
Wheel mice may return buttons 4 and 5.
Those buttons are represented by the same event codes
as buttons 1 and 2 respectively,
except that 64 is added to the event code.
Release events for the wheel buttons are not reported.
By default,
the wheel mouse events are translated to \fIscroll-back\fP
and \fIscroll-forw\fP actions.
Those actions normally scroll the whole window,
as if the scrollbar was used.
However if Alternate Scroll mode is set,
then cursor up/down controls are sent when the terminal is displaying
the alternate screen.
The initial state of Alternate Scroll mode is set
using the \fBalternateScroll\fP resource.
.Ss Highlight tracking
.lP
Mouse highlight tracking notifies a program of a button press, receives a
range of lines from the program, highlights the region covered by
the mouse within that range until button release, and then sends the
program the release coordinates.
It is enabled by specifying parameter 1001 to DECSET.
Highlighting is performed only for button 1, though other button events
can be received.
.sP
\fBWarning:\fP use of this mode requires a cooperating program or it will
hang \fIxterm.\fP
.sP
On button press, the same information as for normal tracking is
generated; \fIxterm\fP then waits for the program to send mouse
tracking information.
\fIAll X events are ignored until the proper escape sequence is
received from the pty:\fP
\*(Cs\*(Ps\*s\*;\*(Ps\*s\*;\*(Ps\*s\*;\*(Ps\*s\*;\*(Ps\*s\*T.
The parameters are \fIfunc, startx, starty, firstrow,\fP and \fIlastrow.\fP
\fIfunc\fP is non-zero to initiate highlight tracking and zero to abort.
\fIstartx\fP and \fIstarty\fP give the starting x and y location for
the highlighted region.
The ending location tracks the mouse, but
will never be above row \fIfirstrow\fP and will always be above row
\fIlastrow.\fP
(The top of the screen is row 1.)
When the button is released, \fIxterm\fP reports the ending position
one of two ways:
.bP
if the start and end coordinates are the same locations:
.br
\*(Cs\*t\*(Cx\*(Cy.
.bP
otherwise:
.br
\*(Cs\*T\*(Cx\*(Cy\*(Cx\*(Cy\*(Cx\*(Cy.
.br
The parameters are \fIstartx, starty, endx, endy, mousex,\fP and \fImousey.\fP
.RS
.IP \- 0.2i
\fIstartx, starty, endx, \fPand\fI endy\fP give the starting and
ending character positions of the region.
.IP \- 0.2i
\fImousex\fP and \fImousey\fP
give the location of the mouse at button up, which may not be over a
character.
.RE
.Ss Button-event tracking
.lP
Button-event tracking is essentially the same as normal tracking, but
\fIxterm\fP also reports button-motion events.
Motion events
are reported only if the mouse pointer has moved to a different character
cell.
It is enabled by specifying parameter 1002 to DECSET.
On button press or release, \fIxterm\fP sends the same codes used by normal
tracking mode.
.bP
On button-motion events, \fIxterm\fP adds 32 to the event code
(the third character, \*(Cb).
.bP
The other bits of the event code specify button and modifier keys as in normal mode.
For example, motion into cell x,y with button 1
down is reported as \*(Cs\*M\*@\*(Cx\*(Cy.
(\ \*@ = 32 + 0 (button 1) + 32 (motion indicator)\ ).
Similarly, motion with button 3
down is reported as \*(Cs\*M\*(cB\*(Cx\*(Cy.
(\ \*(cB = 32 + 2 (button 3) + 32 (motion indicator)\ ).
.Ss Any-event tracking
.lP
Any-event mode is the same as button-event mode, except that all motion
events are reported, even if no mouse button is down.
It is enabled by specifying 1003 to DECSET.
.Ss FocusIn/FocusOut
.lP
FocusIn/FocusOut can be combined with any of the mouse events since
it uses a different protocol.
When set, it causes \fIxterm\fP to send
\*(Cs\*I when the terminal gains focus, and
\*(Cs\*O when it loses focus.
.Ss Extended coordinates
.lP
The original X10 mouse protocol limits the \*(Cx and \*(Cy ordinates
to 223 (=255\ -\ 32).
\fIXterm\fP supports more than one scheme for extending this range,
by changing the protocol encoding:
.IP "UTF-8 (1005)"
This enables UTF-8 encoding for \*(Cx and \*(Cy under
all tracking modes, expanding the maximum encodable position from 223 to 2015.
For positions less than 95, the resulting output is identical under both modes.
Under extended mouse mode, positions greater than 95
generate "extra" bytes which will confuse applications which do not treat
their input as a UTF-8 stream.
Likewise, \*(Cb will be UTF-8 encoded,
to reduce confusion with wheel mouse events.
.IP
Under normal mouse mode, positions outside (160,94) result in
byte pairs which can be interpreted as a single UTF-8 character;
applications
which do treat their input as UTF-8 will almost certainly be confused
unless extended mouse mode is active.
.IP
This scheme has the drawback that the encoded coordinates will not
pass through \fIluit\fP unchanged, e.g., for locales using non-UTF-8 encoding.
.IP "SGR (1006)"
The normal mouse response is altered to use \*(Cs\*<
followed by semicolon-separated
encoded button value,
the \*(Cx and \*(Cy ordinates and a final character which
is \*M for button press
and \*m for button release.
.RS
.bP
The encoded button value in this case does not add 32 since
that was useful only in the X10 scheme for ensuring that the
byte containing the button value is a printable code.
.bP
The modifiers are encoded in the same way.
.bP
A different final character is used for button release
to resolve the X10 ambiguity regarding which button was released.
.RE
.IP
The highlight tracking responses are also modified to an SGR-like format,
using the same SGR-style scheme and button-encodings.
.IP "URXVT (1015)"
The normal mouse response is altered to use \*(Cs
followed by semicolon-separated
encoded button value,
the \*(Cx and \*(Cy ordinates and final character \*M.
.IP
This uses the same button encoding as X10, but printing it as
a decimal integer rather than as a single byte.
.IP
However, \*(Cs\*M can be mistaken for DL (delete lines),
while the highlight tracking \*(Cs\*T can be mistaken for SD (scroll down),
and the Window manipulation controls.
For these reasons, the 1015 control is not recommended;
it is not an improvement over 1005.

with four possible values:
  \*(Pm = 0 \(-> resume command, use fullscreen mode.
  \*(Pm = 1 \(-> start new command, use fullscreen mode.
  \*(Pm = 2 \(-> resume command, use command display mode.
  \*(Pm = 3 \(-> start new command, use command display mode.

Most of these sequences are standard Tektronix 4014 control sequences.
Graph mode supports the 12-bit addressing of the Tektronix 4014.
The major features missing are
the write-through and defocused modes.
This document does not describe the commands used in the various
Tektronix plotting modes but does describe the commands to switch modes.

.TH KOI8RXTERM 1 "__app_date__" "__app_version__" "X Window System"
.SH NAME
koi8rxterm \- X terminal emulator for KOI8-R environments
.SH SYNOPSIS
.B \*n
[
.I xterm-options
]
.SH DESCRIPTION
.B \*n
is a wrapper around the
.BR xterm(1)
program that invokes the latter program with the \*(``KOI8R__default_class__\*('' X
resource class set.
All arguments to
.B \*n
are passed to
.B xterm
without processing; the
.B \-class
and
.B \-k8
options should not be specified because they are used by the wrapper.
See the
.BR xterm
manual page for more information on
.IR xterm-options .
.PP
The environment's locale settings (see \*(``ENVIRONMENT\*('' below) are
used to discern the locale's character set.
If no current locale can be determined, the locale \*(``ru_RU.KOI8-R\*(''
(the Russian language as used in the territory of Russia, with the KOI8-R
character set) is assumed.
The
.BR locale(1)
utility is used to determine whether the system supports the selected
locale.
If it does not,
.B \*n
will exit with an error and report the output of
.BR locale .
.PP
.B Note: \*n
may produce unexpected results if the current locale is set to one in which
the KOI8-R character encoding is not supported, or if fonts using that
encoding are not available.
In the Debian system, the \*(``xfonts\-cyrillic\*('' package provides the
fonts that
.B \*n
uses by default.
To change the fonts
.B \*n
uses, edit the
.I __apploaddir__/KOI8R__default_class__
file.
.PP
A similar wrapper,
.BR uxterm(1),
is available for Unicode UTF-8 environments.
.SH ENVIRONMENT
.TP
.B LC_ALL\fR, \fBLC_CTYPE\fR, \fBLANG
The values of these variables are checked, in order, to determine the
character set used by the current locale.
.SH AUTHOR
.B \*n
was written by Branden Robinson and is very heavily based on
.BR uxterm ,
by Thomas Dickey.
The assistance of Jurij Smakov was invaluable in sanity-checking its
operation.

These scripts and datafiles are used for generating tables used in the
UTF-8 implementation in xterm.

To run the convmap.pl script, you will need a copy of UnicodeData.txt
which is currently available as

         ftp://ftp.unicode.org/Public/UNIDATA/UnicodeData.txt

It is a large file (>1Mb), so it is not included in this distribution.

convmap.pl is used to generate ../keysym2ucs.c, e.g.,

	./convmap.pl >../keysym2ucs.c

keysym.map is input data for convmap.pl

The make-precompose.sh script makes the precompose.c file, which is used to
handle canonical composition. This also needs UnicodeData.txt. It uses
precompose.c.head and precompose.c.tail as templates.

print < UTF-8 conversion will hopefully one day be provided
 * by Xlib via XmbLookupString() and should ideally not have to be
 * done in X applications. But we are not there yet.
 *
 * We allow to represent any UCS character in the range U-00000000 to
 * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
 * This admittedly does not cover the entire 31-bit space of UCS, but
 * it does cover all of the characters up to U-10FFFF, which can be
 * represented by UTF-16, and more, and it is very unlikely that higher
 * UCS codes will ever be assigned by ISO. So to get Unicode character
 * U+ABCD you can directly use keysym 0x0100abcd.
 *
 * NOTE: The comments in the table below contain the actual character
 * encoded in UTF-8, so for viewing and editing best use an editor in
 * UTF-8 mode.

 * Discussing this with Todd Larason in mid-1999, my point was that given the
 * high cost of obtaining ITU T.416 (ISO-8613-6), the standard was not going
 * to be effective (more than $100 then, more than $200 in 2012)
 *
 * We overlooked the detail about ":" as a subparameter delimiter (documented
 * in 5.4.t2 in ECMA-48).  Some discussion in KDE in mid-2006 led Lars Doelle
 * to discuss the issue with me.  Lars' initial concern dealt with the fact
 * that a sequence such as
 *	CSI 38 ; 5 ; 1 m
 * violated the principle that SGR parameters could be used in any order.
 * Further discussion (see KDE #107487) resolved that the standard expected
 * that the sequence would look like
 *	CSI 38 ; 5 : 1 m
 * which still violates that principle, since the "5:1" parameter has to
 * follow the "38" to be useful.
 *
 * This function accepts either format (per request by Paul Leonerd Evans).
 * It also accepts
 *	CSI 38 : 5 : 1 m
 * according to Lars' original assumption.
 *
 * By the way - all of the parameters are decimal integers.

Definitions

c    The literal character c.

C    A single (required) character.

Ps   A single (usually optional) numeric parameter, composed of one of
     more digits.

Pm   A multiple numeric parameter composed of any number of single
     numeric parameters, separated by ;  character(s).  Individual val-
     ues for the parameters are listed with Ps .

Pt   A text parameter composed of printable characters.

Control Bytes, Characters, and Sequences

ECMA-48 (aka "ISO 6429") documents C1 (8-bit) and C0 (7-bit) codes.
Those are respectively codes 128 to 159 and 0 to 31.  ECMA-48 avoids
referring to these codes as characters, because that term is associated
with graphic characters.  Instead, it uses "bytes" and "codes", with
occasional lapses to "characters" where the meaning cannot be mistaken.

Controls (including the escape code 27) are processed once:

o This means that a C1 control can be mistaken for badly-formed UTF-8
  when the terminal runs in UTF-8 mode because C1 controls are valid
  continuation bytes of a UTF-8 encoded (multibyte) value.

o It is not possible to use a C1 control obtained from decoding the
  UTF-8 text, because that would require reprocessing the data.  Conse-
  quently there is no ambiguity in the way this document uses the term
  "character" to refer to bytes in a control sequence.

The order of processing is a necessary consequence of the way ECMA-48 is
designed:

o Each byte sent to the terminal can be unambiguously determined to fall
  into one of a few categories (C0, C1 and graphic characters).

o ECMA-48 is modal; once it starts processing a control sequence, the
  terminal continues until the sequence is complete, or some byte is
  found which is not allowed in the sequence.

o Intermediate, parameter and final bytes may use the same codes as
  graphic characters, but they are processed as part of a control
  sequence and are not actually graphic characters.

o Eight-bit controls can have intermediate, etc., bytes in the range 160
  to 255.  Those can be treated as their counterparts in the range 32 to
  127.

o Single-byte controls can be handled separately from multi-byte control
  sequences because ECMA-48's rules are unambiguous.

  As a special case, ECMA-48 (section 9) mentions that the control func-
  tions shift-in and shift-out are allowed to occur within a 7-bit
  multibyte control sequence because those cannot alter the meaning of
  the control sequence.

o Some controls (such as OSC ) introduce a string mode, which is ended
  on a ST  (string terminator).

  Again, the terminal should accept single-byte controls within the
  string.  However, xterm has a resource setting brokenLinuxOSC to allow
  recovery from applications which rely upon malformed palette sequences
  used by the Linux console.

C1 (8-Bit) Control Characters

The xterm program recognizes both 8-bit and 7-bit control characters.
It generates 7-bit controls (by default) or 8-bit if S8C1T is enabled.
The following pairs of 7-bit and 8-bit control characters are equiva-
lent:

ESC D
     Index (IND  is 0x84).
ESC E
     Next Line (NEL  is 0x85).
ESC H
     Tab Set (HTS  is 0x88).
ESC M
     Reverse Index (RI  is 0x8d).
ESC N
     Single Shift Select of G2 Character Set (SS2  is 0x8e).  This
     affects next character only.
ESC O
     Single Shift Select of G3 Character Set (SS3  is 0x8f).  This
     affects next character only.
ESC P
     Device Control String (DCS  is 0x90).
ESC V
     Start of Guarded Area (SPA  is 0x96).
ESC W
     End of Guarded Area (EPA  is 0x97).
ESC X
     Start of String (SOS  is 0x98).
ESC Z
     Return Terminal ID (DECID is 0x9a).  Obsolete form of CSI c  (DA).
ESC [
     Control Sequence Introducer (CSI  is 0x9b).
ESC \
     String Terminator (ST  is 0x9c).
ESC ]
     Operating System Command (OSC  is 0x9d).
ESC ^
     Privacy Message (PM  is 0x9e).
ESC _
     Application Program Command (APC  is 0x9f).

These control characters are used in the vtXXX emulation.

VT100 Mode
Most of these control sequences are standard VT102 control sequences,
but there is support for later DEC VT terminals (i.e., VT220, VT320,
VT420, VT510), as well as ISO 6429 and aixterm color controls.  The only
VT102 feature not supported is auto-repeat, since the only way X pro-
vides for this will affect all windows.
There are additional control sequences to provide xterm-dependent func-
tions, such as the scrollbar or window size.  Where the function is
specified by DEC or ISO 6429, the code assigned to it is given in paren-
theses.
The escape codes to designate and invoke character sets are specified by
ISO 2022 (see that document for a discussion of character sets).
Many of the features are optional; xterm can be configured and built
without support for them.

Single-character functions
BEL       Bell (Ctrl-G).
BS        Backspace (Ctrl-H).
CR        Carriage Return (Ctrl-M).
ENQ       Return Terminal Status (Ctrl-E).  Default response is an empty
          string, but may be overridden by a resource answerbackString.
FF        Form Feed or New Page (NP).  (FF  is Ctrl-L).  FF  is treated
          the same as LF .
LF        Line Feed or New Line (NL).  (LF  is Ctrl-J).
SI        Shift In (Ctrl-O) -> Switch to Standard Character Set.  This
          invokes the G0 character set (the default).
SO        Shift Out (Ctrl-N) -> Switch to Alternate Character Set.  This
          invokes the G1 character set.
SP        Space.
TAB       Horizontal Tab (HT) (Ctrl-I).
VT        Vertical Tab (Ctrl-K).  This is treated the same as LF.

Controls beginning with ESC
This excludes controls where ESC  is part of a 7-bit equivalent to 8-bit
C1 controls, ordered by the final character(s).
ESC SP F  7-bit controls (S7C1T).
ESC SP G  8-bit controls (S8C1T).
ESC SP L  Set ANSI conformance level 1 (dpANS X3.134.1).
ESC SP M  Set ANSI conformance level 2 (dpANS X3.134.1).
ESC SP N  Set ANSI conformance level 3 (dpANS X3.134.1).
ESC # 3   DEC double-height line, top half (DECDHL).
ESC # 4   DEC double-height line, bottom half (DECDHL).
ESC # 5   DEC single-width line (DECSWL).
ESC # 6   DEC double-width line (DECDWL).
ESC # 8   DEC Screen Alignment Test (DECALN).
ESC % @   Select default character set.  That is ISO 8859-1 (ISO 2022).
ESC % G   Select UTF-8 character set (ISO 2022).
ESC ( C   Designate G0 Character Set (ISO 2022, VT100).
          Final character C for designating 94-character sets.  In this
          list, 0 , A  and B  apply to VT100 and up, the remainder to
          VT220 and up.  The VT220 character sets, together with the
          Portuguese character set are activated by the National
          Replacement Character controls.  The A  is a special case,
          since it is also activated by the VT300-control for British
          Latin-1 separately from the National Replacement Character
          controls.

Application Program-Command functions
APC Pt ST None.  xterm implements no APC  functions; Pt is ignored.  Pt
          need not be printable characters.

Device-Control functions
DCS Ps; Ps| Pt ST
          User-Defined Keys (DECUDK).  The first parameter:
            Ps = 0  -> Clear all UDK definitions before starting
          (default).
            Ps = 1  -> Erase Below (default).
          The second parameter:
            Ps = 0  <- Lock the keys (default).
            Ps = 1  <- Do not lock.
          The third parameter is a ';'-separated list of strings denot-
          ing the key-code separated by a '/' from the hex-encoded key
          value.  The key codes correspond to the DEC function-key codes
          (e.g., F6=17).
DCS $ q Pt ST
          Request Status String (DECRQSS).  The string following the "q"
          is one of the following:
            " q     -> DECSCA
            " p     -> DECSCL
            r       -> DECSTBM
            s       -> DECSLRM
            m       -> SGR
            SP q    -> DECSCUSR
          xterm responds with DCS 1 $ r Pt ST for valid requests,
          replacing the Pt with the corresponding CSI string, or DCS 0 $
          r Pt ST for invalid requests.
DCS + p Pt ST
          Set Termcap/Terminfo Data (xterm, experimental).  The string
          following the "p" is a name to use for retrieving data from
          the terminal database.  The data will be used for the "tcap"
          keyboard configuration's function- and special-keys, as well
          as by the Request Termcap/Terminfo String control.
DCS + q Pt ST
          Request Termcap/Terminfo String (xterm, experimental).  The
          string following the "q" is a list of names encoded in hexa-
          decimal (2 digits per character) separated by ; which corre-
          spond to termcap or terminfo key names.
          Two special features are also recognized, which are not key
          names: Co for termcap colors (or colors for terminfo colors),
          and TN for termcap name (or name for terminfo name).
          xterm responds with DCS 1 + r Pt ST for valid requests, adding
          to Pt an = , and the value of the corresponding string that
          xterm would send, or DCS 0 + r Pt ST for invalid requests.
          The strings are encoded in hexadecimal (2 digits per charac-
          ter).

CSI Ps P  Delete Ps Character(s) (default = 1) (DCH).
CSI Ps S  Scroll up Ps lines (default = 1) (SU).
CSI ? Pi; Pa; Pv S
          If configured to support either Sixel Graphics or ReGIS Graph-
          ics, xterm accepts a three-parameter control sequence, where
          Pi, Pa and Pv are the item, action and value:

            Pi = 1  -> item is number of color registers.
            Pi = 2  -> item is Sixel graphics geometry (in pixels).
            Pi = 3  -> item is ReGIS graphics geometry (in pixels).

            Pa = 1  -> read
            Pa = 2  -> reset to default
            Pa = 3  -> set to value in Pv
            Pa = 4  -> read the maximum allowed value

            Pv can be omitted except when setting (Pa == 3 ).
            Pv = n <- A single integer is used for color registers.
            Pv = width; height <- Two integers for graphics geometry.

          xterm replies with a control sequence of the same form:

               CSI ? Pi; Ps; Pv S

          where Ps is the status:
            Ps = 0  -> success.
            Ps = 1  -> error in Pi.
            Ps = 2  -> error in Pa.
            Ps = 3  -> failure.

          On success, Pv represents the value read or set.

          Notes:
          o The current implementation allows reading the graphics
            sizes, but disallows modifying those sizes because that is
            done once, using resource-values.
          o Graphics geometry is not necessarily the same as "window
            size" (see the dtterm window manipulation extensions). For
            example, xterm limits the maximum graphics geometry at com-
            pile time (1000x1000 as of version 328) although the window
            size can be larger.
          o While resizing a window will always change the current
            graphics geometry, the reverse is not true.  Setting graph-
            ics geometry does not affect the window size.
CSI Ps T  Scroll down Ps lines (default = 1) (SD).
CSI Ps ; Ps ; Ps ; Ps ; Ps T
          Initiate highlight mouse tracking.  Parameters are
          [func;startx;starty;firstrow;lastrow].  See the section Mouse
          Tracking.
CSI > Ps; Ps T
          Reset one or more features of the title modes to the default
          value.  Normally, "reset" disables the feature.  It is possi-
          ble to disable the ability to reset features by compiling a
          different default for the title modes into xterm.
            Ps = 0  -> Do not set window/icon labels using hexadecimal.
            Ps = 1  -> Do not query window/icon labels using hexadeci-
          mal.

            -> CSI ? 6 3 ; Psc  ("VT320")
            -> CSI ? 6 4 ; Psc  ("VT420")
          The VT100-style response parameters do not mean anything by
          themselves.  VT220 (and higher) parameters do, telling the
          host what features the terminal supports:
            Ps = 1  -> 132-columns.
            Ps = 2  -> Printer.
            Ps = 3  -> ReGIS graphics.
            Ps = 4  -> Sixel graphics.
            Ps = 6  -> Selective erase.

            Ps = 1 5  -> Technical characters.
            Ps = 1 8  -> User windows.
            Ps = 2 1  -> Horizontal scrolling.
            Ps = 2 2  -> ANSI color, e.g., VT525.
            Ps = 2 9  -> ANSI text locator (i.e., DEC Locator mode).
CSI > Ps c
          Send Device Attributes (Secondary DA).
            Ps = 0  or omitted -> request the terminal's identification
          code.  The response depends on the decTerminalID resource set-
          ting.  It should apply only to VT220 and up, but xterm extends
          this to VT100.

            Ps = 9  -> Crossed-out characters (ISO 6429).
            Ps = 2 1  -> Doubly-underlined (ISO 6429).

            Ps = 3 2  -> Set foreground color to Green.
            Ps = 3 3  -> Set foreground color to Yellow.
            Ps = 3 4  -> Set foreground color to Blue.
            Ps = 3 5  -> Set foreground color to Magenta.
            Ps = 3 6  -> Set foreground color to Cyan.
            Ps = 3 7  -> Set foreground color to White.
            Ps = 3 9  -> Set foreground color to default (original).
            Ps = 4 0  -> Set background color to Black.
            Ps = 4 1  -> Set background color to Red.
            Ps = 4 2  -> Set background color to Green.
            Ps = 4 3  -> Set background color to Yellow.
            Ps = 4 4  -> Set background color to Blue.
            Ps = 4 5  -> Set background color to Magenta.
            Ps = 4 6  -> Set background color to Cyan.
            Ps = 4 7  -> Set background color to White.
            Ps = 4 9  -> Set background color to default (original).

          If 16-color support is compiled, the following apply.  Assume
          that xterm's resources are set so that the ISO color codes are
          the first 8 of a set of 16.  Then the aixterm colors are the
          bright versions of the ISO colors:
            Ps = 9 0  -> Set foreground color to Black.
            Ps = 9 1  -> Set foreground color to Red.
            Ps = 9 2  -> Set foreground color to Green.
            Ps = 9 3  -> Set foreground color to Yellow.
            Ps = 9 4  -> Set foreground color to Blue.
            Ps = 9 5  -> Set foreground color to Magenta.
            Ps = 9 6  -> Set foreground color to Cyan.
            Ps = 9 7  -> Set foreground color to White.
            Ps = 1 0 0  -> Set background color to Black.
            Ps = 1 0 1  -> Set background color to Red.
            Ps = 1 0 2  -> Set background color to Green.
            Ps = 1 0 3  -> Set background color to Yellow.
            Ps = 1 0 4  -> Set background color to Blue.
            Ps = 1 0 5  -> Set background color to Magenta.
            Ps = 1 0 6  -> Set background color to Cyan.
            Ps = 1 0 7  -> Set background color to White.

          If xterm is compiled with the 16-color support disabled, it
          supports the following, from rxvt:
            Ps = 1 0 0  -> Set foreground and background color to
          default.

          Xterm maintains a color palette whose entries are identified
          by an index beginning with zero.  If 88- or 256-color support
          is compiled, the following apply:
          o All parameters are decimal integers.
          o RGB values range from zero (0) to 255.
          o ISO-8613-3 can be interpreted in more than one way; xterm
            allows the semicolons in this control to be replaced by
            colons (but after the first colon, colons must be used).

          These ISO-8613-3 controls are supported:
            Pm = 3 8 ; 2 ; Pr; Pg; Pb -> Set foreground color to the
          closest match in xterm's palette for the given RGB Pr/Pg/Pb.
            Pm = 3 8 ; 5 ; Ps -> Set foreground color to Ps.
            Pm = 4 8 ; 2 ; Pr; Pg; Pb -> Set background color to the
          closest match in xterm's palette for the given RGB Pr/Pg/Pb.
            Pm = 4 8 ; 5 ; Ps -> Set background color to Ps.

CSI > Ps; Ps m
          Set or reset resource-values used by xterm to decide whether
          to construct escape sequences holding information about the
          modifiers pressed with a given key.  The first parameter iden-
          tifies the resource to set/reset.  The second parameter is the
          value to assign to the resource.  If the second parameter is
          omitted, the resource is reset to its initial value.
            Ps = 0  -> modifyKeyboard.
            Ps = 1  -> modifyCursorKeys.
            Ps = 2  -> modifyFunctionKeys.
            Ps = 4  -> modifyOtherKeys.
          If no parameters are given, all resources are reset to their
          initial values.
CSI Ps n  Device Status Report (DSR).
            Ps = 5  -> Status Report.
          Result ("OK") is CSI 0 n
            Ps = 6  -> Report Cursor Position (CPR) [row;column].
          Result is CSI r ; c R

          Note: it is possible for this sequence to be sent by a func-
          tion key.  For example, with the default keyboard configura-
          tion the shifted F1 key may send (with shift-, control-, alt-
          modifiers)
            CSI 1  ; 2  R , or
            CSI 1  ; 5  R , or
            CSI 1  ; 6  R , etc.
          The second parameter encodes the modifiers; values range from
          2 to 16.  See the section PC-Style Function Keys for the
          codes.  The modifyFunctionKeys and modifyKeyboard resources
          can change the form of the string sent from the modified F1
          key.

CSI > Ps n
          Disable modifiers which may be enabled via the CSI > Ps; Ps m
          sequence.  This corresponds to a resource value of "-1", which
          cannot be set with the other sequence.  The parameter identi-
          fies the resource to be disabled:
            Ps = 0  -> modifyKeyboard.
            Ps = 1  -> modifyCursorKeys.
            Ps = 2  -> modifyFunctionKeys.
            Ps = 4  -> modifyOtherKeys.
          If the parameter is omitted, modifyFunctionKeys is disabled.
          When modifyFunctionKeys is disabled, xterm uses the modifier
          keys to make an extended sequence of functions rather than
          adding a parameter to each function key to denote the modi-
          fiers.
CSI ? Ps n
          Device Status Report (DSR, DEC-specific).
            Ps = 6  -> Report Cursor Position (DECXCPR) [row;column] as

              The x's are hexadecimal digits 0-9 and A-F.
            Ps = 7 5  -> Report data integrity as CSI ? 7 0 n  (ready,

CSI Pt ; Pl ; Pb ; Pr ' w
          Enable Filter Rectangle (DECEFR), VT420 and up.
          Parameters are [top;left;bottom;right].
          Defines the coordinates of a filter rectangle and activates
          it.  Anytime the locator is detected outside of the filter
          rectangle, an outside rectangle event is generated and the
          rectangle is disabled.  Filter rectangles are always treated
          as "one-shot" events.  Any parameters that are omitted default
          to the current locator position.  If all parameters are omit-
          ted, any locator motion will be reported.  DECELR always can-
          cels any prevous rectangle definition.
CSI Ps x  Request Terminal Parameters (DECREQTPARM).
          if Ps is a "0" (default) or "1", and xterm is emulating VT100,
          the control sequence elicits a response of the same form whose
          parameters describe the terminal:
            Ps -> the given Ps incremented by 2.
            Pn = 1  <- no parity.
            Pn = 1  <- eight bits.
            Pn = 1  <- 2  8  transmit 38.4k baud.
            Pn = 1  <- 2  8  receive 38.4k baud.

CSI Pi ; Pg ; Pt; Pl; Pb; Pr * y
          Request Checksum of Rectangular Area (DECRQCRA), VT420 and up.
          Response is
          DCS Pi ! x x x x ST
            Pi is the request id.
            Pg is the page number.
            Pt; Pl; Pb; Pr denotes the rectangle.
            The x's are hexadecimal digits 0-9 and A-F.
CSI Ps ; Pu ' z
          Enable Locator Reporting (DECELR).
          Valid values for the first parameter:
            Ps = 0  -> Locator disabled (default).
            Ps = 1  -> Locator enabled.
            Ps = 2  -> Locator enabled for one report, then disabled.
          The second parameter specifies the coordinate unit for locator
          reports.
          Valid values for the second parameter:
            Pu = 0  <- or omitted -> default to character cells.
            Pu = 1  <- device physical pixels.
            Pu = 2  <- character cells.
CSI Pt; Pl; Pb; Pr$ z
          Erase Rectangular Area (DECERA), VT400 and up.
            Pt; Pl; Pb; Pr denotes the rectangle.
CSI Pm ' {
          Select Locator Events (DECSLE).
          Valid values for the first (and any additional parameters)
          are:
            Ps = 0  -> only respond to explicit host requests (DECRQLP).
                       (This is default).  It also cancels any filter
                       rectangle.
            Ps = 1  -> report button down transitions.
            Ps = 2  -> do not report button down transitions.
            Ps = 3  -> report button up transitions.
            Ps = 4  -> do not report button up transitions.
CSI Pt; Pl; Pb; Pr $ {
          Selective Erase Rectangular Area (DECSERA), VT400 and up.
            Pt; Pl; Pb; Pr denotes the rectangle.
CSI Ps ' |
          Request Locator Position (DECRQLP).
          Valid values for the parameter are:
            Ps = 0 , 1 or omitted -> transmit a single DECLRP locator
          report.

          If Locator Reporting has been enabled by a DECELR, xterm will
          respond with a DECLRP Locator Report.  This report is also
          generated on button up and down events if they have been
          enabled with a DECSLE, or when the locator is detected outside
          of a filter rectangle, if filter rectangles have been enabled
          with a DECEFR.

            -> CSI Pe ; Pb ; Pr ; Pc ; Pp &  w

          Parameters are [event;button;row;column;page].
          Valid values for the event:
            Pe = 0  -> locator unavailable - no other parameters sent.
            Pe = 1  -> request - xterm received a DECRQLP.
            Pe = 2  -> left button down.
            Pe = 3  -> left button up.
            Pe = 4  -> middle button down.
            Pe = 5  -> middle button up.
            Pe = 6  -> right button down.
            Pe = 7  -> right button up.
            Pe = 8  -> M4 button down.
            Pe = 9  -> M4 button up.
            Pe = 1 0  -> locator outside filter rectangle.
          The "button" parameter is a bitmask indicating which buttons
          are pressed:
            Pb = 0  <- no buttons down.
            Pb & 1  <- right button down.
            Pb & 2  <- middle button down.
            Pb & 4  <- left button down.
            Pb & 8  <- M4 button down.
          The "row" and "column" parameters are the coordinates of the
          locator position in the xterm window, encoded as ASCII deci-
          mal.
          The "page" parameter is not used by xterm.
CSI Pm ' }
          Insert Ps Column(s) (default = 1) (DECIC), VT420 and up.
CSI Pm ' ~
          Delete Ps Column(s) (default = 1) (DECDC), VT420 and up.

Operating System Commands
OSC Ps ; Pt BEL
OSC Ps ; Pt ST
          Set Text Parameters.  For colors and font, if Pt is a "?", the
          control sequence elicits a response which consists of the con-
          trol sequence which would set the corresponding value.  The
          dtterm control sequences allow you to determine the icon name
          and window title.
            Ps = 0  -> Change Icon Name and Window Title to Pt.
            Ps = 1  -> Change Icon Name to Pt.
            Ps = 2  -> Change Window Title to Pt.
            Ps = 3  -> Set X property on top-level window.  Pt should be
          in the form "prop=value", or just "prop" to delete the prop-
          erty
            Ps = 4 ; c; spec -> Change Color Number c to the color spec-
          ified by spec.  This can be a name or RGB specification as per
          XParseColor.  Any number of c/spec pairs may be given.  The
          color numbers correspond to the ANSI colors 0-7, their bright
          versions 8-15, and if supported, the remainder of the 88-color
          or 256-color table.

          If a "?" is given rather than a name or RGB specification,
          xterm replies with a control sequence of the same form which
          can be used to set the corresponding color.  Because more than
          one pair of color number and specification can be given in one
          control sequence, xterm can make more than one reply.

            Ps = 5 ; c; spec -> Change Special Color Number c to the
          color specified by spec.  This can be a name or RGB specifica-
          tion as per XParseColor.  Any number of c/spec pairs may be
          given.  The special colors can also be set by adding the maxi-
          mum number of colors to these codes in an OSC 4  control:

              Pc = 0  <- resource colorBD (BOLD).
              Pc = 1  <- resource colorUL (UNDERLINE).
              Pc = 2  <- resource colorBL (BLINK).
              Pc = 3  <- resource colorRV (REVERSE).
              Pc = 4  <- resource colorIT (ITALIC).

            Ps = 6 ; c; f -> Enable/disable Special Color Number c.  OSC
          6  is the same as OSC 1 0 6 .

          The 10 colors (below) which may be set or queried using 1 0
          through 1 9  are denoted dynamic colors, since the correspond-
          ing control sequences were the first means for setting xterm's
          colors dynamically, i.e., after it was started.  They are not
          the same as the ANSI colors.  These controls may be disabled
          using the allowColorOps resource.  At least one parameter is
          expected for Pt.  Each successive parameter changes the next
          color in the list.  The value of Ps tells the starting point
          in the list.  The colors are specified by name or RGB specifi-
          cation as per XParseColor.

          If a "?" is given rather than a name or RGB specification,
          xterm replies with a control sequence of the same form which
          can be used to set the corresponding dynamic color.  Because
          more than one pair of color number and specification can be
          given in one control sequence, xterm can make more than one
          reply.

            Ps = 1 0  -> Change VT100 text foreground color to Pt.
            Ps = 1 1  -> Change VT100 text background color to Pt.
            Ps = 1 2  -> Change text cursor color to Pt.
            Ps = 1 3  -> Change mouse foreground color to Pt.
            Ps = 1 4  -> Change mouse background color to Pt.
            Ps = 1 5  -> Change Tektronix foreground color to Pt.
            Ps = 1 6  -> Change Tektronix background color to Pt.
            Ps = 1 7  -> Change highlight background color to Pt.
            Ps = 1 8  -> Change Tektronix cursor color to Pt.
            Ps = 1 9  -> Change highlight foreground color to Pt.

            Ps = 4 6  -> Change Log File to Pt.  (This is normally dis-
          abled by a compile-time option).

            Ps = 5 0  -> Set Font to Pt.  These controls may be disabled
          using the allowFontOps resource.  If Pt begins with a "#",
          index in the font menu, relative (if the next character is a
          plus or minus sign) or absolute.  A number is expected but not
          required after the sign (the default is the current entry for
          relative, zero for absolute indexing).
          The same rule (plus or minus sign, optional number) is used
          when querying the font.  The remainder of Pt is ignored.
          A font can be specified after a "#" index expression, by
          adding a space and then the font specifier.
          If the "TrueType Fonts" menu entry is set (the renderFont
          resource), then this control sets/queries the faceName
          resource.

            Ps = 5 1  -> reserved for Emacs shell.

            Ps = 5 2  -> Manipulate Selection Data.  These controls may
          be disabled using the allowWindowOps resource.  The parameter
          Pt is parsed as
               Pc; Pd
          The first, Pc, may contain zero or more characters from the
          set c  p  s  0  1  2  3  4  5  6  7 .  It is used to construct
          a list of selection parameters for clipboard, primary, select,
          or cut buffers 0 through 7 respectively, in the order given.
          If the parameter is empty, xterm uses s 0 , to specify the
          configurable primary/clipboard selection and cut buffer 0.
          The second parameter, Pd, gives the selection data.  Normally
          this is a string encoded in base64.  The data becomes the new
          selection, which is then available for pasting by other appli-
          cations.
          If the second parameter is a ? , xterm replies to the host
          with the selection data encoded using the same protocol.
          If the second parameter is neither a base64 string nor ? ,
          then the selection is cleared.

            Ps = 1 0 4 ; c -> Reset Color Number c.  It is reset to the
          color specified by the corresponding X resource.  Any number
          of c parameters may be given.  These parameters correspond to
          the ANSI colors 0-7, their bright versions 8-15, and if sup-
          ported, the remainder of the 88-color or 256-color table.  If
          no parameters are given, the entire table will be reset.

            Ps = 1 0 5 ; c -> Reset Special Color Number c.  It is reset
          to the color specified by the corresponding X resource.  Any
          number of c parameters may be given.  These parameters corre-
          spond to the special colors which can be set using an OSC 5
          control (or by adding the maximum number of colors using an
          OSC 4  control).

            Ps = 1 0 6 ; c; f -> Enable/disable Special Color Number c.
          The second parameter tells xterm to enable the corresponding
          color mode if nonzero, disable it if zero.

              Pc = 0  <- resource colorBDMode (BOLD).
              Pc = 1  <- resource colorULMode (UNDERLINE).
              Pc = 2  <- resource colorBLMode (BLINK).
              Pc = 3  <- resource colorRVMode (REVERSE).
              Pc = 4  <- resource colorITMode (ITALIC).
              Pc = 5  <- resource colorAttrMode (Override ANSI).

          The dynamic colors can also be reset to their default
          (resource) values:
            Ps = 1 1 0  -> Reset VT100 text foreground color.
            Ps = 1 1 1  -> Reset VT100 text background color.
            Ps = 1 1 2  -> Reset text cursor color.
            Ps = 1 1 3  -> Reset mouse foreground color.
            Ps = 1 1 4  -> Reset mouse background color.
            Ps = 1 1 5  -> Reset Tektronix foreground color.
            Ps = 1 1 6  -> Reset Tektronix background color.
            Ps = 1 1 7  -> Reset highlight color.
            Ps = 1 1 8  -> Reset Tektronix cursor color.
            Ps = 1 1 9  -> Reset highlight foreground color.

Alt and Meta Keys
Many keyboards have keys labeled "Alt".  Few have keys labeled "Meta".
However, xterm's default translations use the Meta modifier.  Common
keyboard configurations assign the Meta modifier to an "Alt" key.  By
using xmodmap one may have the modifier assigned to a different key, and
have "real" alt and meta keys.  Here is an example:

     ! put meta on mod3 to distinguish it from alt
     keycode 64 = Alt_L
     clear mod1
     add mod1 = Alt_L
     keycode 115 = Meta_L
     clear mod3
     add mod3 = Meta_L


The metaSendsEscape resource (and altSendsEscape if altIsNotMeta is set)
can be used to control the way the Meta modifier applies to ordinary
keys unless the modifyOtherKeys resource is set:
          - prefix a key with the ESC  character.
          - shift the key from codes 0-127 to 128-255 by adding 128.

The table shows the result for a given character "x" with modifiers
according to the default translations with the resources set on or off.
This assumes altIsNotMeta is set:

PC-Style Function Keys
If xterm does minimal translation of the function keys, it usually does
this with a PC-style keyboard, so PC-style function keys result.  Sun
keyboards are similar to PC keyboards.  Both have cursor and scrolling
operations printed on the keypad, which duplicate the smaller cursor and
scrolling keypads.

X does not predefine NumLock (used for VT220 keyboards) or Alt (used as
an extension for the Sun/PC keyboards) as modifiers.  These keys are
recognized as modifiers when enabled by the numLock resource, or by the
"DECSET 1 0 3 5 " control sequence.

The cursor keys transmit the following escape sequences depending on the
mode specified via the DECCKM escape sequence.

                  Key            Normal     Application
                  -------------+----------+-------------
                  Cursor Up    | CSI A    | SS3 A
                  Cursor Down  | CSI B    | SS3 B
                  Cursor Right | CSI C    | SS3 C
                  Cursor Left  | CSI D    | SS3 D
                  -------------+----------+-------------

The home- and end-keys (unlike PageUp and other keys also on the 6-key
editing keypad) are considered "cursor keys" by xterm.  Their mode is
also controlled by the DECCKM escape sequence:

                    Key        Normal     Application
                    ---------+----------+-------------
                    Home     | CSI H    | SS3 H
                    End      | CSI F    | SS3 F
                    ---------+----------+-------------


The application keypad transmits the following escape sequences depend-
ing on the mode specified via the DECKPNM and DECKPAM escape sequences.
Use the NumLock key to override the application mode.

Not all keys are present on the Sun/PC keypad (e.g., PF1, Tab), but are
supported by the program.

They also provide 12 function keys, as well as a few other special-pur-
pose keys:

                       ---------+-----------------


Note that F1 through F4 are prefixed with SS3 , while the other keys are
prefixed with CSI .  Older versions of xterm implement different escape
sequences for F1 through F4, with a CSI  prefix.  These can be activated
by setting the oldXtermFKeys resource.  However, since they do not cor-
respond to any hardware terminal, they have been deprecated.  (The DEC
VT220 reserves F1 through F5 for local functions such as Setup).

                       Key        Escape Sequence
                       ---------+-----------------
                       F1       | CSI 1 1 ~
                       F2       | CSI 1 2 ~

                       ---------+-----------------

In normal mode, i.e., a Sun/PC keyboard when the sunKeyboard resource is
false (and none of the other keyboard resources such as oldXtermFKeys
resource is set), xterm encodes function key modifiers as parameters
appended before the final character of the control sequence.  As a spe-
cial case, the SS3  sent before F1 through F4 is altered to CSI  when
sending a function key modifier as a parameter.

                     7     | Alt + Control
                     8     | Shift + Alt + Control
                     9     | Meta

                     15    | Meta + Ctrl + Alt
                     16    | Meta + Ctrl + Alt + Shift
                  ---------+---------------------------

For example, shift-F5 would be sent as CSI 1 5 ; 2 ~

If the alwaysUseMods resource is set, the Meta modifier also is recog-
nized, making parameters 9 through 16.

VT220-Style Function Keys
However, xterm is most useful as a DEC VT102 or VT220 emulator.  Set the
sunKeyboard resource to true to force a Sun/PC keyboard to act like a
VT220 keyboard.

The VT102/VT220 application keypad transmits unique escape sequences in
application mode, which are distinct from the cursor and scrolling key-
pad:

The VT220 provides a 6-key editing keypad, which is analogous to that on
the PC keyboard.  It is not affected by DECCKM or DECKPNM/DECKPAM:

                   ---------+----------+-------------

The VT220 provides 8 additional function keys.  With a Sun/PC keyboard,
access these keys by Control/F1 for F13, etc.

VT52-Style Function Keys
A VT52 does not have function keys, but it does have a numeric keypad
and cursor keys.  They differ from the other emulations by the prefix.
Also, the cursor keys do not change:

                   Key            Normal/Application
                   -------------+--------------------

Sun-Style Function Keys
The xterm program provides support for Sun keyboards more directly, by a
menu toggle that causes it to send Sun-style function key codes rather
than VT220.  Note, however, that the sun and VT100 emulations are not
really compatible.  For example, their wrap-margin behavior differs.

Only function keys are altered; keypad and cursor keys are the same.
The emulation responds identically.  See the xterm-sun terminfo entry
for details.

HP-Style Function Keys
Similarly, xterm can be compiled to support HP keyboards.  See the
xterm-hp terminfo entry for details.

The Alternate Screen Buffer
Xterm maintains two screen buffers.  The normal screen buffer allows you
to scroll back to view saved lines of output up to the maximum set by
the saveLines resource.  The alternate screen buffer is exactly as large
as the display, contains no additional saved lines.  When the alternate
screen buffer is active, you cannot scroll back to view saved lines.
Xterm provides control sequences and menu entries for switching between
the two.

Most full-screen applications use terminfo or termcap to obtain strings
used to start/stop full-screen mode, i.e., smcup and rmcup for terminfo,
or the corresponding ti and te for termcap.  The titeInhibit resource
removes the ti and te strings from the TERMCAP string which is set in
the environment for some platforms.  That is not done when xterm is
built with terminfo libraries because terminfo does not provide the
whole text of the termcap data in one piece.  It would not work for ter-
minfo anyway, since terminfo data is not passed in environment vari-
ables; setting an environment variable in this manner would have no
effect on the application's ability to switch between normal and alter-
nate screen buffers.  Instead, the newer private mode controls (such as
1 0 4 9 ) for switching between normal and alternate screen buffers sim-
ply disable the switching.  They add other features such as clearing the
display for the same reason: to make the details of switching indepen-
dent of the application that requests the switch.

Bracketed Paste Mode
When bracketed paste mode is set, pasted text is bracketed with control
sequences so that the program can differentiate pasted text from typed-
in text.  When bracketed paste mode is set, the program will receive:
   ESC [ 2 0 0 ~ ,
followed by the pasted text, followed by
   ESC [ 2 0 1 ~ .

Title Modes
The window- and icon-labels can be set or queried using control
sequences.  As a VT220-emulator, xterm "should" limit the character
encoding for the corresponding strings to ISO-8859-1.  Indeed, it used
to be the case (and was documented) that window titles had to be
ISO-8859-1.  This is no longer the case.  However, there are many appli-
cations which still assume that titles are set using ISO-8859-1.  So
that is the default behavior.

If xterm is running with UTF-8 encoding, it is possible to use window-
and icon-labels encoded using UTF-8.  That is because the underlying X
libraries (and many, but not all) window managers support this feature.

The utf8Title X resource setting tells xterm to disable a reconversion
of the title string back to ISO-8859-1, allowing the title strings to be
interpreted as UTF-8.  The same feature can be enabled using the title
mode control sequence described in this summary.

Separate from the ability to set the titles, xterm provides the ability
to query the titles, returning them either in ISO-8859-1 or UTF-8.  This
choice is available only while xterm is using UTF-8 encoding.

Finally, the characters sent to, or returned by a title control are less
constrained than the rest of the control sequences.  To make them more
manageable (and constrained), for use in shell scripts, xterm has an
optional feature which decodes the string from hexadecimal (for setting
titles) or for encoding the title into hexadecimal when querying the
value.

Mouse Tracking
The VT widget can be set to send the mouse position and other informa-
tion on button presses.  These modes are typically used by editors and
other full-screen applications that want to make use of the mouse.

There are two sets of mutually exclusive modes:
o mouse protocol
o protocol encoding

The mouse protocols include DEC Locator mode, enabled by the DECELR CSI
Ps ; Ps  '  z control sequence, and is not described here (control
sequences are summarized above).  The remaining five modes of the mouse
protocols are each enabled (or disabled) by a different parameter in the
"DECSET CSI ? Pm h " or "DECRST CSI ? Pm l " control sequence.

Manifest constants for the parameter values are defined in xcharmouse.h
as follows:

     #define SET_X10_MOUSE               9
     #define SET_VT200_MOUSE             1000
     #define SET_VT200_HIGHLIGHT_MOUSE   1001
     #define SET_BTN_EVENT_MOUSE         1002
     #define SET_ANY_EVENT_MOUSE         1003

     #define SET_FOCUS_EVENT_MOUSE       1004

     #define SET_EXT_MODE_MOUSE          1005
     #define SET_SGR_EXT_MODE_MOUSE      1006
     #define SET_URXVT_EXT_MODE_MOUSE    1015

     #define SET_ALTERNATE_SCROLL        1007

The motion reporting modes are strictly xterm extensions, and are not
part of any standard, though they are analogous to the DEC VT200 DECELR
locator reports.

Normally, parameters (such as pointer position and button number) for
all mouse tracking escape sequences generated by xterm encode numeric
parameters in a single character as value+32.  For example, !  specifies
the value 1.  The upper left character position on the terminal is
denoted as 1,1.  This scheme dates back to X10, though the normal mouse-
tracking (from X11) is more elaborate.
X10 compatbility mode

X10 compatibility mode sends an escape sequence only on button press,
encoding the location and the mouse button pressed.  It is enabled by
specifying parameter 9 to DECSET.  On button press, xterm sends CSI M
CbCxCy (6 characters).
o Cb is button-1.
o Cx and Cy are the x and y coordinates of the mouse when the button was
  pressed.
Normal tracking mode

Normal tracking mode sends an escape sequence on both button press and
release.  Modifier key (shift, ctrl, meta) information is also sent.  It
is enabled by specifying parameter 1000 to DECSET.  On button press or
release, xterm sends CSI M CbCxCy.
o The low two bits of Cb encode button information: 0=MB1 pressed, 1=MB2
  pressed, 2=MB3 pressed, 3=release.
o The next three bits encode the modifiers which were down when the but-
  ton was pressed and are added together:  4=Shift, 8=Meta, 16=Control.
  Note however that the shift and control bits are normally unavailable
  because xterm uses the control modifier with mouse for popup menus,
  and the shift modifier is used in the default translations for button
  events.  The Meta modifier recognized by xterm is the mod1 mask, and
  is not necessarily the "Meta" key (see xmodmap).
o Cx and Cy are the x and y coordinates of the mouse event, encoded as
  in X10 mode.
Wheel mice

Wheel mice may return buttons 4 and 5.  Those buttons are represented by
the same event codes as buttons 1 and 2 respectively, except that 64 is
added to the event code.  Release events for the wheel buttons are not
reported.  By default, the wheel mouse events are translated to scroll-
back and scroll-forw actions.  Those actions normally scroll the whole
window, as if the scrollbar was used.  However if Alternate Scroll mode
is set, then cursor up/down controls are sent when the terminal is dis-
playing the alternate screen.  The initial state of Alternate Scroll
mode is set using the alternateScroll resource.
Highlight tracking

Mouse highlight tracking notifies a program of a button press, receives
a range of lines from the program, highlights the region covered by the
mouse within that range until button release, and then sends the program
the release coordinates.  It is enabled by specifying parameter 1001 to
DECSET.  Highlighting is performed only for button 1, though other but-
ton events can be received.

Warning: use of this mode requires a cooperating program or it will hang
xterm.

On button press, the same information as for normal tracking is gener-
ated; xterm then waits for the program to send mouse tracking informa-
tion.  All X events are ignored until the proper escape sequence is
received from the pty: CSI Ps ; Ps ; Ps ; Ps ; Ps T .  The parameters
are func, startx, starty, firstrow, and lastrow.  func is non-zero to
initiate highlight tracking and zero to abort.  startx and starty give
the starting x and y location for the highlighted region.  The ending
location tracks the mouse, but will never be above row firstrow and will
always be above row lastrow.  (The top of the screen is row 1.)  When
the button is released, xterm reports the ending position one of two
ways:
o if the start and end coordinates are the same locations:
  CSI t CxCy.
o otherwise:
  CSI T CxCyCxCyCxCy.
  The parameters are startx, starty, endx, endy, mousex, and mousey.
  - startx, starty, endx, and endy give the starting and ending charac-
    ter positions of the region.
  - mousex and mousey give the location of the mouse at button up, which
    may not be over a character.
Button-event tracking

Button-event tracking is essentially the same as normal tracking, but
xterm also reports button-motion events.  Motion events are reported
only if the mouse pointer has moved to a different character cell.  It
is enabled by specifying parameter 1002 to DECSET.  On button press or
release, xterm sends the same codes used by normal tracking mode.
o On button-motion events, xterm adds 32 to the event code (the third
  character, Cb).
o The other bits of the event code specify button and modifier keys as
  in normal mode.  For example, motion into cell x,y with button 1 down
  is reported as CSI M @ CxCy.  ( @  = 32 + 0 (button 1) + 32 (motion
  indicator) ).  Similarly, motion with button 3 down is reported as CSI
  M B CxCy.  ( B  = 32 + 2 (button 3) + 32 (motion indicator) ).
Any-event tracking

Any-event mode is the same as button-event mode, except that all motion
events are reported, even if no mouse button is down.  It is enabled by
specifying 1003 to DECSET.
FocusIn/FocusOut

FocusIn/FocusOut can be combined with any of the mouse events since it
uses a different protocol.  When set, it causes xterm to send CSI I
when the terminal gains focus, and CSI O  when it loses focus.
Extended coordinates

The original X10 mouse protocol limits the Cx and Cy ordinates to 223
(=255 - 32).  Xterm supports more than one scheme for extending this
range, by changing the protocol encoding:
UTF-8 (1005)
          This enables UTF-8 encoding for Cx and Cy under all tracking
          modes, expanding the maximum encodable position from 223 to
          2015.  For positions less than 95, the resulting output is
          identical under both modes.  Under extended mouse mode, posi-
          tions greater than 95 generate "extra" bytes which will con-
          fuse applications which do not treat their input as a UTF-8
          stream.  Likewise, Cb will be UTF-8 encoded, to reduce confu-
          sion with wheel mouse events.
          Under normal mouse mode, positions outside (160,94) result in
          byte pairs which can be interpreted as a single UTF-8 charac-
          ter; applications which do treat their input as UTF-8 will
          almost certainly be confused unless extended mouse mode is
          active.
          This scheme has the drawback that the encoded coordinates will
          not pass through luit unchanged, e.g., for locales using non-
          UTF-8 encoding.
SGR (1006)
          The normal mouse response is altered to use CSI < followed by
          semicolon-separated encoded button value, the Cx and Cy ordi-
          nates and a final character which is M  for button press and m
          for button release.
          o The encoded button value in this case does not add 32 since
            that was useful only in the X10 scheme for ensuring that the
            byte containing the button value is a printable code.
          o The modifiers are encoded in the same way.
          o A different final character is used for button release to
            resolve the X10 ambiguity regarding which button was
            released.
          The highlight tracking responses are also modified to an SGR-
          like format, using the same SGR-style scheme and button-encod-
          ings.
URXVT (1015)
          The normal mouse response is altered to use CSI followed by
          semicolon-separated encoded button value, the Cx and Cy ordi-
          nates and final character M .
          This uses the same button encoding as X10, but printing it as
          a decimal integer rather than as a single byte.
          However, CSI M  can be mistaken for DL (delete lines), while
          the highlight tracking CSI T  can be mistaken for SD (scroll
          down), and the Window manipulation controls.  For these rea-
          sons, the 1015 control is not recommended; it is not an
          improvement over 1005.

Sixel Graphics
If xterm is configured as VT240, VT241, VT330, VT340 or VT382 using the
decTerminalID resource, it supports Sixel Graphics controls, a palleted
bitmap graphics system using sets of six vertical pixels as the basic
element.

CSI Ps c  xterm responds to Send Device Attributes (Primary DA) with
          these additional codes:
            Ps = 4  -> Sixel graphics.
CSI ? Pm h
          xterm has these additional private Set Mode values:
            Ps = 8 0  -> Sixel scrolling.
            Ps = 1 0 7 0  -> use private color registers for each
          graphic.
            Ps = 8 4 5 2  -> Sixel scrolling leaves cursor to right of
          graphic.
DCS Pa; Pb; Ph q  Ps..Ps ST
          See:

               http://vt100.net/docs/vt3xx-gp/chapter14.html

          The sixel data device control string has three positional
          parameters, following the q  with sixel data.
            Pa -> pixel aspect ratio
            Pb -> background color option
            Ph -> horizontal grid size (ignored).
            Ps -> sixel data

ReGIS Graphics
If xterm is configured as VT125, VT240, VT241, VT330 or VT340 using the
decTerminalID resource, it supports Remote Graphic Instruction Set, a
graphics description language.

CSI Ps c  xterm responds to Send Device Attributes (Primary DA) with
          these additional codes:
            Ps = 3  -> ReGIS graphics.
CSI ? Pm h
          xterm has these additional private Set Mode values:
            Ps = 1 0 7 0  -> use private color registers for each
          graphic.
DCS Pm p Pr..Pr ST
          See:

               http://vt100.net/docs/vt3xx-gp/chapter1.html

          The ReGIS data device control string has one positional param-
          eter with four possible values:
            Pm = 0 -> resume command, use fullscreen mode.
            Pm = 1 -> start new command, use fullscreen mode.
            Pm = 2 -> resume command, use command display mode.
            Pm = 3 -> start new command, use command display mode.

Tektronix 4014 Mode
Most of these sequences are standard Tektronix 4014 control sequences.
Graph mode supports the 12-bit addressing of the Tektronix 4014.  The
major features missing are the write-through and defocused modes.  This
document does not describe the commands used in the various Tektronix
plotting modes but does describe the commands to switch modes.

			Abandon All Hope, Ye Who Enter Here


This is undoubtedly the most ugly program in the distribution.  It was one of
the first "serious" programs ported, and still has a lot of historical baggage.
Ideally, there would be a general tty widget and then vt102 and tek4014 
subwidgets so that they could be used in other programs.  We are trying to 
clean things up as we go, but there is still a lot of work to do.

If you are porting this to a machine that has problems with overlapping
bcopy's, watch out!

There are two documents on xterm: the man page, xterm.man, which describes
how to use it, and ctlseqs.ms, which describes the control sequences it
understands.

/*
 * Unlike NRCS, which splices a few characters onto ASCII, the supplementary
 * character sets are complete, normally mapped to GR.  Most of these mappings
 * rely upon glyphs not found in ISO-8859-1.  We can display most of those
 * using Unicode, thereby supporting specialized applications that use SCS
 * with luit, subject to the limitation that select/paste will give meaningless
 * results in terms of the application which uses these mappings.
 *
 * Since the VT320, etc, use only 8-bit encodings, there is no plausible
 * argument to be made that these mappings "use" UTF-8, even though there is
 * a hidden step in the terminal emulator which relies upon UTF-8.

.SH NAME
uxterm \- X terminal emulator for Unicode (UTF-8) environments
.SH SYNOPSIS
.B \*n
[
.I xterm-options
]
.SH DESCRIPTION
.B \*n
is a wrapper around the
.BR xterm(1)
program that invokes the latter program with the \*(``U__default_class__\*('' X resource
class set.
All arguments to
.B \*n
are passed to
.B xterm
without processing; the
.B \-class
and
.B \-u8
options should not be specified because they are used by the wrapper.
See the
.B xterm
manual page for more information on
.IR xterm-options .
.PP
The environment's locale settings (see \*(``ENVIRONMENT\*('' below) are
used to discern the locale's character set.
If no current locale can be determined, the locale \*(``en_US\*('' (the
English language as used in the territory of the United States) is assumed.
The
.BR locale(1)
utility is used to determine whether the system supports the selected
locale.
If it does not,
.B \*n
will exit with an error and report the output of
.BR locale .
.PP
.B Note: \*n
may produce unexpected results if the current locale is set to one in which
the UTF-8 character encoding is not supported, or if fonts using the ISO
10646-1 character set are not available.
In the Debian system, the \*(``xfonts\-base\*('' package provides the fonts
that
.B \*n
uses by default.
To change the fonts
.B \*n
uses, edit the
.I __apploaddir__/U__default_class__
file.
.PP
A similar wrapper,
.BR koi8rxterm(1),
is available for KOI8-R environments.
.SH ENVIRONMENT
.TP
.B LC_ALL\fR, \fBLC_CTYPE\fR, \fBLANG
The values of these variables are checked, in order, to determine the
character set used by the current locale.

Here is
  the latest version of this file.


  
It began as a list of the changes that I made for xterm, using
  the notes that I added when submitting a patch. You should note
  that other changes were made as well, by other people, to fix
  bugs and correct ifdef's for portability. Until mid-2006, most of
  these were summarized in the XFree86 
  CHANGELOG).


  

  
Patch #330 -
  2017/06/20


  
    
    
  • updates for ReGIS (Ross Combs):

      
      
        
    • remove redundant text command error check which broke
        T(B) and T(E).
      • 

        
    • retain the loading alphabet number across multiple
        “L” commands.
      • 

        
    • add S(T) delay handler.
      • 

        
    • fix some color handling error messages.
      • 

        
    • add stubbed-out macrograph handling.
      • 

        
    • use fragment_remaining() and
        fragment_consumed() instead of manually
        checking position / length in various places.
      • 

        
    • rename some local variables in string / extent / option
        parsing
      • 

        
    • wrap some long lines.
      • 

        
    • move macrograph command handling out of the
        top-level.
      • 
      
    
    
    • 

    
  • add a summary of the italic fonts loaded to
    -report-fonts option.
    • 

    
  • modify the font-lookup for italics to allow for
    “-i-” if no match is found with slant
    “-o-” (prompted by patch by Ben
    Wong).
    • 

    
  • change default values for mkSamplePass and
    mkSampleSize to reflect generally-improved locale
    support in various operating systems (FreeBSD #219800).
    • 

    
  • modify wcwidth.c to return -1 for non-Unicode
    values, and adjust a couple of blocks to better match
    assumptions about ambiguous-width characters in other
    implementations. Also modify wcwidth.c to support
    configurable soft-hyphen, so there is no drawback to using this
    version rather than a system wcwidth.
    • 

    
  • amend change made in patch #328
    for cursor-visibility to handle case where an application is
    updating the reverse-video state (FreeBSD #219800).
    • 

    
  • update tables of combining and ambiguous-width characters
    in wcwidth.c based on Unicode 10.0.0.
    • 

    
  • build-fix for --enable-sixel-graphics without
    --enable-regis-graphics (reports by Sven Joachim,
    FreeBSD #219945).
    • 
  


  
Patch #329 -
  2017/06/12


  
    
    
  • add control sequences for reading the Sixel and ReGIS
    graphics sizes (suggested by Ben Wong).
    • 

    
  • add a workaround for wcwidth returning -1 for
    characters which should have been printable (FreeBSD
    #219800).
    • 

    
  • fix a bug in font initialization from patch #328 (FreeBSD #219800).
    • 

    
  • fix a special case in HideCursor which
    assigned a bold font to the slot used for normal font in
    changes for italics in patch #307
    (Debian #858304).
    • 

    
  • updates for ReGIS (Ross Combs):

      
      
        
    • Strings specified with no command are used as
        "comments". Print these in the log when tracing.
      • 

        
    • Catch attempts to use "alternate display" mode (AKA
        "blink") from the GIGI, but do not implement it.
      • 

        
    • The T(M) command should only multiply the
        height by 10, not 20.
      • 

        
    • Make the S(E) command reset more state
        than just the screen contents.
      • 

        
    • Remove two rotation variables which were only being
        printed.
      • 

        
    • Numerous minor fixes and comment updates in the
        R command.
      • 

        
    • Unknown R command option names trigger an
        empty response.
      • 

        
    • Fix the output position after printing rotated text (it
        was missing the the sign before).
      • 

        
    • Fix the position change with pixelvectors and rotated
        text (the rotation transform was not being applied).
      • 

        
    • Update the TODO list and remove a verification
        FIXME (slanted text positioning is correct as
        is).
      • 

        
    • Emulate the approximately 1.4x enlargement for text
        which isn't rotated at right angles.
      • 

        
    • Only update the color planes specified in the plane
        mask (the W command's F
        option).
      • 
      
    
    
    • 

    
  • fix a bug introduced by the changes to font information in
    patch #328. When processing the
    "checkfont" option of the locale resource, the
    program referred to the request data, to an array
    which was only allocated in the new/result widget
    (report by H Merijn Brand).
    • 

    
  • fix a missing assignment initialization to make the
    utf8 resource control whether escape sequences to
    enable/disable UTF-8 mode are allowed.
    • 
  


  
Patch #328 -
  2017/06/01


  
    
    
  • revise parser for charClass resource, making
    these improvements:

      
      
        
    • accept octal and hexadecimal values
      • 

        
    • allow embedded whitespace
      • 

        
    • allow the class after colon to be optional, e.g., to
        clear class settings for a range of characters.
      • 
      
    
    
    • 

    
  • add command-line option
    -report-charclass.
    • 

    
  • fix most lintian warnings about test-package
    • 

    
  • add eraseSavedLines resource.
    • 

    
  • document DECSED 3 in
    ctlseqs.ms (report by Ben Longmans).
    • 

    
  • improve integration between configure-events and updates
    for reported screensize, in particular when switching between
    vt100 and tek4014 modes.
    • 

    
  • modify selection-highlighting of reverse-video text to keep
    that distinct, e.g., by reversing the selection foreground and
    background colors as one would expect. This fixes a "useless"
    case in the description of
    highlightColorMode.
    • 

    
  • improve fix for Debian #759734, addressing a case where
    non-colored cursor would be invisible against reverse-video
    (see patch #311).
    • 

    
  • updates for ReGIS (Ross Combs):

      
      
        
    • the "H" option of the "T" command should multiply by
        10, not 20.
      • 

        
    • display unknown glyphs as a solid block.
      • 

        
    • given a succession of text-direction options, use the
        last.
      • 

        
    • fix the direction of ReGIS slanted text so that
        negative values produce oblique output .
      • 

        
    • fix the ReGIS text direction option to only rotate
        characters when no following size option is used.
      • 
      
    
    
    • 

    
  • update terminfo to better match corresponding entries in
    ncurses, e.g., u8 pattern to match the VT220,
    VT420, etc., primary responses, as well as adding
    smxx and rmxx.
    • 

    
  • fixes from Jörg Sommer:

      
      
        
    • corrected a trace-message regarding maximum
        graphics-size; it used the similar ReGIS maximum size which
        might not be configured.
      • 

        
    • in do_select_regex, clear selection if
        there is no match. If the regex does not match anything
        around the cursor, the selection returned must be empty,
        otherwise the whole line is treated as a match. This way
        the command defined by exec-selectable will
        not be executed if there is no match.
      • 

        
    • modify limit in do_select_regex to include
        the character at the cursor in the match, making it easier
        to type something and then hit the key to trigger
        exec-selectable.
      • 

        
    • If exec-selectable or
        insert-selection is triggered by a mouse
        button click, the position of the mouse pointer should be
        used. This makes it easier to address any position on the
        window and it makes it possible to use the mouse, e.g., for
        applications such as mutt where you cannot move the
        cursor.
      • 
      
    
    
    • 

    
  • modify DECRC to save/restore xterm's
    last-column flag used to control wrapping behavior rather than
    manipulating DECAWM (report/analysis by Mattias
    Engdegård).
    • 

    
  • add configure option --enable-terminfo-env to
    use the value set by --with-own-terminfo for the
    $TERMINFO environment variable. That variable was
    set automatically for HPUX, but would be useful in other
    systems, e.g., for Solaris (request by Jeff Wieland).
    • 

    
  • fix a race condition when setting up a signal handler to
    timeout if opening /dev/tty hangs (patch by Tobias
    Stoeckmann).
    • 

    
  • review/cleanup resources which were not in the manual page
    (report by Maxwell Anselm):

      
      
        
    • add manual page description as needed.
      • 

        
    • drop resource name for menuBar, as
        unnecessary.
      • 

        
    • modify fallback numeric value for
        regisScreenSize resource to match that for
        maxGraphicSize.
      • 
      
    
    
    • 

    
  • updated configure macros CF_ADD_CFLAGS,
    CF_CC_ENV_FLAGS, CF_GNU_SOURCE,
    CF_MATH_LIB, and CF_XOPEN_SOURCE from
    other program-changes.
    • 

    
  • update config.guess, config.sub
    • 

    
  • change “maximum screensize” assumed by
    resize to 9999x9999, to accommodate people using
    the Unreadable font.
    • 

    
  • drop Utility from default value of
    --with-desktop-category (Debian #780176).
    • 

    
  • widen the configure script pattern used for finding related
    ".desktop" files, including “Terminal”
    • 

    
  • several minor improvements to font utility functions:

      
      
        
    • provide for later modification to implement font-sets
        by parsing the font resources as comma-separated
        lists.
      • 

        
    • parse -fn and -fa similarly,
        using “x:” and “xft:” prefixes for
        font name/family strings to distinguish between XLFD and
        Xft font specifications.
      • 

        
    • use loops to iterate over font classes
      • 

        
    • use getters/setters for font data to allow for
        on-demand lookups.
      • 

        
    • make the debugging trace for missing glyph less verbose
        since that interferes with the -report-fonts
        option.
      • 

        
    • refactor xtermLoadFont to make it clearer
        how some fonts are derived from others, e.g., bold,
        wide.
      • 

        
    • make the triggering and suppressing of font-warnings
        more consistent by storing the last state in the
        widget.
      • 

        
    • reduce font-warnings by checking for repeated
        warnings.
      • 
      
    
    
    • 

    
  • add vttests/query-status.pl
    • 

    
  • add vttests/closest-rgb
    • 

    
  • add special case for displaying soft-hyphen if it happens
    to fall at the right margin, and omitting similar case such as
    the BIDI markers, where a zero-width character is neither a
    control character nor a combining character (Debian
    #844325).
    • 

    
  • modify logic for OSC 52, manipulate
    selection data, to update the selection-time to include
    the latest X events. This fixes some cases where the selection
    was invalid, e.g., after an event due to focus-follows-mouse
    (report/testcase by Stephane Chauveau).
    • 

    
  • revise macro CastMallocN as new macro
    TextAlloc to make explicit use of
    sizeof(char) (prompted by patch by Cade
    Foster).
    • 

    
  • add “Mouse Ops” menu entry and related
    resources to allow runtime disabling/enabling of the mouse
    protocol escape sequences (discussion with Bob Proulx).
    • 

    
  • improve discussion of mouse actions versus protocol in the
    manual (discussion with Bob Proulx).
    • 

    
  • improve discussion of environment variables in the manual,
    pointing out where some features (such as termcap and the
    System5 COLUMNS and LINES variables)
    are used rarely, mainly to support legacy applications.
    • 

    
  • add examples of translations resource for
    select/paste, and for font-size changes to the manual.
    • 

    
  • minor reordering of some entries in ctlseqs.ms
    for consistency (report by Arran Ubels).
    • 

    
  • add -s option to 256colors2.pl
    and 88colors2.pl, to demonstrate modifying the
    “system” colors 0–15.
    • 

    
  • omit XFT_SPACING property from call to 
      XftPatternBuild, to work around a bug in
      fontconfig for handling Google Go fonts, whose names
      sort in an order not expected by fontconfig, causing
      the request for a monospaced font to return italics,
      e.g.,

      
    
        
    $ fc-match 'Go Mono:spacing=monospace'
Go-Mono-Italic.ttf: "Go Mono" "Italic"
(report by Giacomo Boffi on Stackoverflow).


    
      
    
    
    • 

    
  • modify minstall.in to improve a workaround
    added to the manual page in patch #182
    to avoid having the C preprocessor used in the imake
    configuration strip out the comments in the character classes
    section (reports by Ted Unangst, Anthony J Bentley).
    • 
  


  
Patch #327 -
  2016/10/07


  
    
    
  • add a check in the function which handles end-of-line
    wrapping to ensure that C1 controls are allocated one column
    when allowC1Printable is set (Debian
    #738794).
    • 

    
  • use consistent error-checking after strtol
    calls, fixes a case where a query with OSC 6 did not ensure
    there was a valid color number (report by Alex Smith).
    • 

    
  • add -baudrate option, for testing
    ncurses.
    • 

    
  • always generate the CASE_xxx symbols
    in VTparse.h and Tekparse.h, as part
    of a change to improve debug-logging. This makes the build
    always depend upon awk.
    • 

    
  • modify allowC1Printable to disallow codes
    160-254 as being equivalent to codes 32-126 when parsing escape
    sequences (Debian #839220).
    • 

    
  • amend fix from patch #326 for
    TrueType fonts to exclude the hidden character used for
    double-width cells (report by Grady Martin).
    • 

    
  • fix a typo in ctlseqs.ms
    • 
  


  
Patch #326 -
  2016/09/25


  
    
    
  • updated appdata file (report by Richard Hughes).
    • 

    
  • improve discussion of the different terminal emulations
    provided by xterm in the manual page.
    • 

    
  • add examples of setting the icon title with/without the
    window title in the manual (Debian #833984).
    • 

    
  • correct a limit-check when using a numeric value for
    extended Booleans e.g., *fullscreen:3 rather than
    a name such as *fullscreen:never.
    • 

    
  • add action allow-bold-fonts
    • 

    
  • improved formatting fixes for manual page, using script to
    find mismatches in spelling of resources, actions and menu
    entries.
    • 

    
  • improve documentation of logging resources.
    • 

    
  • fix a special case of flickering cursor by adding
    GraphicsExpose to the list of event types that
    should not trigger making the mouse cursor visible (patch by
    Joe Peterson).
    • 

    
  • correct initialization of line-drawing in VT52-mode,
    overlooked in changes for patch #297
    (report/patch by Ben Wiley Sittler).
    • 

    
  • minor clarification of form-feed versus line-feed in
    ctlseqs.ms (suggested by David Kemper).
    • 

    
  • amend fix for Debian #738794 to restore a check for missing
    characters which are not combining characters. Also
    fill in a corresponding special case for TrueType fonts (Debian
    #827905).
    • 
  


  
Patch #325 -
  2016/06/05


  
    
    
  • improve manual page discussion of function keys (discussion
    with Ross Combs).
    • 

    
  • further improve fix for Debian #545220 in patch #248, to avoid conflict with combining
    characters (Debian #738794).
    • 

    
  • improve -hold option to avoid 100% CPU usage
    with NetBSD after closing the shell, which makes subsequent
    checks for X input events fail (prompted by patch by Pierre
    Pronchery).
    • 

    
  • review #ifdef statements, listed those which
    do not have a configure option in
    xtermcfg.hin.
    • 

    
  • fixed one case where the menu sensistivity for
    Print-All Immediately and Print-All on Error
    was not properly ifdef'd.
    • 

    
  • modify terminfo entries for 16-, 88- and 256-color to reset
    palette with rs1 capability.
    • 

    
  • accept legacy value of -kt as
    synonym for the oldXtermFKeys resource, and extend
    the full-reset logic to use the keyboard type set via
    -kt.
    • 

    
  • modify ioctl calls for I_PUSH to
    first check if the module has been added, using
    I_FIND. This is needed for newer Solaris libraries
    with c11 support (adapted from patch by Alan Coopersmith).
    • 

    
  • add check in getXtermCombining to ensure that
    combining characters were allocated (report by Tor
    Andersson).
    • 

    
  • add configure option --without-xinerama to
    allow suppressing the extension (Gentoo #580936).
    • 

    
  • update keysym2ucs.c based on Unicode 9.0
    • 

    
  • fixed most cppcheck --enable=all warnings,
    including for style (prompted by report by David Binderman).
    There was one bug-fix:

      
      
        
    • RGB least-squares computation in
        allocateClosestRGB used only one ordinate
      • 
      
    
    
    • 

    
  • add cppcheck to lint-like programs in
    configure script and makefile.
    • 

    
  • fix some const correctness issues and point out an array
    lifetime issue (Ross Combs).
    • 

    
  • updates for SIXEL and ReGIS (Ross Combs):

      
      
        
    • Sixel drawing should still happen after an error if
        some commands have been processed
      • 

        
    • Tiny steps toward reporting ReGIS input
      • 
      
    
    
    • 
  


  
Patch #324 -
  2016/03/10


  
    
    
  • updated configure macro CF_LD_RPATH_OPT from
    ncurses changes.
    • 

    
  • provide alternate fix for Juha Nurmela's report by turning
    on POSIX signals if _POSIX_C_SOURCE is at least
    one. This is done to improve the behavior if a direct child
    process receives a STOP signal.

    discussion with Poul-Henning Kamp).
    • 

    
  • modify check for cursor-theme from patch #301 to also check if the resource
    Xcursor.theme is set to a nonempty value before
    fallback to xterm's own dummy theme (request by Robert
    Kloefkorn).
    • 

    
  • explain in ctlseqs.ms that some keys which
    normally send SS3-prefixes are changed to CSI-prefixes if
    key-modifiers are passed as parameters (report by George
    Nachman).
    • 

    
  • correct double-free of font information when multiple

  2015/04/12


  
    
    
  • rename new(er) configure option

    • 

    
  • add a short usage section to the xterm manual, including
    notes on setting the window title (Debian #742477).
    • 

    
  • revise a change made to ICH in patch #314 to address limit-checks
    (reports/testcases by Zoltán Kéri and Joe
    Peterson, also reported by Christian Weisgerber).
    • 
  


  
Patch #316 -
  2015/03/07


  
    
    
  • revert change to make DCH honor top/bottom
    scrolling margins. For the record, both the VT420 and VT520
    reference manuals incorrectly state that "DCH has no effect
    outside the scrolling margins."
    • 

    
  • fix regression in DCH introduced in adjustment
    for limit-check in patch #315
    (report/testcase by Zoltán Kéri, also reported by
    Christian Weisgerber).
    • 

    
  • correct default value for configure option
    --enable-initial-erase; it should be "False", but
    in patch #315 it was "Maybe", which
    differed from default set in patch
    #192.
    • 
  


  
Patch #315 -
  2015/03/02

    OSC 6, avoiding conflict with one of
    Terminal.app's undocumented escape sequences (report by Egmont
    Koblinger).
    • 

    
  • fix an off-by-one in comparison when autowrap and
    left/right margins are combined (report by George
    Nachman).
    • 

    
  • modify DECBI and DECFI to work
    outside the left/right margins, since the vague VT520 reference
    manual could support that interpretation (suggested by George
    Nachman).
    • 

    
  • correct response for DECSCUSR in
    DECRQSS (report/analysis by George Nachman).
    • 

    
  • add DECSLRM to list for DECRQSS
    in ctlseqs.ms (report by George Nachman).

    margins (report by George Nachman).
    •

    honors left/right margins (report by George Nachman).
    • 

    
  • correct logic of DECSCL, which always set
    8-bit controls as a side-effect (report by George
    Nachman).
    • 

    
  • correct loop limit for DECSED 1, when
    DECSCA is enabled (report by George Nachman).
    • 

    
  • fix a entry in csi_table for “$”,
    needed for CSI [ $ z
    (report by George Nachman).
    • 

    
  • remove restriction from patch #279
    changes on DECIC and DECDC to
    left-right mode (report by George Nachman).
    • 

    
  • correct PID value returned in response to DECRQCRA
    (report/analysis by George Nachman).
    • 

    
  • fix an ifdef'ing problem, where
    --disable-dec-locator would turn off logic needed
    for DECIC and DECDC (report by George
    Nachman).
    • 

    
  • correct order of parameters in report for
    CSI 1 9 t, which gives the
    screensize in characters (report by George Nachman).
    • 

    
  • add null pointer checks for a case in DECCRA where part of
    the target rectangle lies outside the screen limits (report by
    George Nachman).
    • 

    
  • remove extra "6" for selective erase from DA1 response
    (report by George Nachman).
    • 

    
  • support Xinerama screen specification in geometry parsing
    (patch by Nicolas George).
    • 

    
  • add configure option --enable-initial-erase to
    set ptyInitialErase consistently with manpage, as
    well as adding a table in manpage to clarify the relationship
    between the resources related to the backarrow key (Debian
    #775952).
    • 

    
  • add configure --enable-builtin-xpms to
    simplify compiling-in the icons introduced in patch #284 (prompted by discussion with
    William Bulley).
    • 

    
  • fix/improve autoconf macros:

      
      
        
    • CF_WITH_APP_DEFAULTS, add paths for OSX
      • 

        
    • CF_WITH_MAN2HTML, configure option "--with-man2html"
        provides "man2html" as alternative to groff's man/html
        conversion
      • 
      
    
    
    • 

    
  • fix some minor issues in manpage (Jens Schweikhardt).
    • 
  


  
Patch #314 -
  2014/12/28


  
    
    
  • fix a minor bug in the termcap-specific version of
    resize when the lines or columns values are at the
    very end of an incomplete termcap string (prompted by coverity
    report).
    • 

    
  • improve paste64 feature (report by Olaf Rogalsky)

      
      
        
    • fix “p;” command in
        paste64.pl example.
      • 

        
    • modify _OwnSelection to allow the paste64
        control to cause primary/clipboard selections to be
        disowned and cleared.
      • 

        
    • omit an extra "=" used in padding, to make the base64
        response a multiple of four characters.
      • 

        
    • modify _ConvertSelectionHelper to not stop
        converting on embedded nulls in the primary or clipboard
        selection. That makes the behavior consistent with
        cut-buffers. Nulls are not passed on to the application
        because they are used for separators in the X library calls
        that convert XTextProperty values.
      • 
      
    
    
    • 

    
  • add configure option --with-man2html to allow
    an alternative to groff's man/html conversion.
    • 

    
  • review and modify resource-settings which can be set via
    control sequences, etc:

      
      
        
    • add OSC 6, to enable/disable colors
        set via OSC 5, without changing the color
        assignments (prompted by patch by Ingo Brückl).
      • 

        
    • add command-line option -itc for
        italics.
      • 

        
    • add colorIT and colorITMode
        for italics, like colorBD, etc.
      • 

        
    • guard allowPasteControls against
        modification by editres.
      • 
      
    
    
    • 

    
  • change passedPty from fixed-length to
    allocated to ensure that it is long enough to hold the
    -S option value (report by Ben Longbons).
    • 

    
  • improve ReGIS graphics initialization (Ross Combs):

      
      
        
    • add a new string resource to set the default ReGIS
        font.
      • 

        
    • fix a caching problem where the font name wasn't taken
        into consideration when looking up cached metrics.
      • 

        
    • enables use of fractional values in coordinates (which
        in turn allows setting the coordinates to something like
        [0,1][1,0])
      • 

        
    • doubles the minimum ReGIS graphic to 200x200
      • 

        
    • set the default ReGIS image size to "auto"
      • 

        
    • fix some swapped width/height parameters in TRACE
        messages
      • 

        
    • add support for scaling and mirrored coordinate systems
        to the screen address command
      • 

        
    • sets a minimum ReGIS graphics size of 100x100 --
        smaller address ranges will be scaled up
      • 

        
    • reset the image if either the width or height is zero
        (which should happen together or not at all, but switching
        the logic gets rid of some parentheses)
      • 

        
    • adds support for alternate screen coordinates (just
        offsets, not inverted coordinates or scaling)
      • 

        
    • keeps the graphics state across ReGIS calls unless P1
        or P3 entry codes are used
      • 

        
    • changes loops to continue after parsing whitespace to
        allow trailing whitespace
      • 

        
    • fixes some incorrect character casts
      • 
      
    
    
    • 
  


  
Patch #313 -
  2014/11/28


  
    
    
  • add regisScreenSize resource setting to allow
    custom screensizes for ReGIS graphics (prompted by discussion
    with Scott Froebe).
    • 

    
  • fix some minor issues in manpage (Jens Schweikhardt).
    • 

    
  • improve ReGIS font-handling (Ross Combs):

      
      
        
    • remove "random junk" generation for unknown
        characters
      • 

        
    • add xterm extension to load user glyphs for alphabet
        0
      • 

        
    • add xterm extension to specify loading an alphabet from
        a font by name
      • 

        
    • fix bug with use of empty alphabet slots which caused
        slot 0 to be clobbered
      • 

        
    • update/clarify ReGIS-related comments
      • 

        
    • add DECprint extension for printing/clearing the screen
        (only clearing is performed)
      • 
      
    
    
    • 

    
  • improve ReGIS colorspec conversion (Ross Combs):

      
      
        
    • avoid some floating point math for colorspace
        conversion
      • 

        
    • move two copies of colorspec parsing to a single
        function
      • 

        
    • change colorspec parsing to handle components being out
        of order or with spaces and commas between them
      • 

        
    • add support for an extension where RGB components can
        be given instead of HLS
      • 
      
    
    
    • 

    
  • improve use of const, e.g., for the LineData
    pointers (patch by Ross Combs).
    • 

    
  • clip of graphics that overlap the scrollback buffer and alt
    screen (patch by Ross Combs).
    • 

    
  • amend change to focus-change events in patch #287 to limit it to suppressing the
    reset of the urgency-hint, because some useful
    FocusOut events were lost (report by Joe
    Peterson).
    • 

    
  • modify dpkg build-script to configure xterm-dev as an
    x-terminal-emulator alternative.
    • 

    
  • extend the --with-xterm-symlink feature to
    make symbolic links for the other programs and scripts.
    • 

    
  • minor fix to vttests/resize.pl to avoid
    undefined variable when receiving broken/missing response,
    e.g., from mrxvt.
    • 

    
  • change the way that ReGIS graphics are refreshed (patch by
    Ross Combs):

      
      
        
    • it pre-composes any overlapping graphics to avoid
        unnecessary and flickering draws
      • 

        
    • it adds a three-dimensional lookup table for RGB ->
        pixel values and uses this across all graphics
      • 

        
    • it draws in line segments when there is a run of the
        same color
      • 

        
    • in cases where there are no transparent parts, it uses
        an XImage to draw
      • 

        
    • it hooks into the double-buffering support if it is
        enabled (though this doesn't seem to get rid of all
        flicker).
      • 
      
    This has the effect of reducing flicker and speeding up
      redraws.
    
    • 
  


  
Patch #312 -
  2014/09/28


  
    
    
  • undo change to do_select_regex() in patch #311 (reports by H Merijn Brand,
    Sven-Haegar Koch, Debian #762978).
    • 
  


  
Patch #311 -
  2014/09/18


  
    
    
  • mention xclip in manpage as an alternative
    workaround for copying clipboard data, noting that
    selectToClipboard (see patch
    #209) is the recommended approach (Debian #639094).
    • 

    
  • correct comparison in do_select_regex() of working position
    against starting column.
    • 

    
  • correct initialization for regular-expression feature of
    exec-selectable and insert-selectable
    actions (Debian #758633).
    • 

    
  • modify logic for exec-formatted and
    insert-formatted actions to ensure that the
    formatting occurs just after the selection is received (Debian
    #758633).
    • 

    
  • account for state of reverse-video in special case of
    cursor coloring (Debian #759734).
    • 

    
  • fix a sign-extension problem in ReGIS support, as well as
    correcting a case where ignored-characters were not really
    ignored (patch by Ross Combs).
    • 

    
  • Enable the "Escape Sequence" menu entry when an OSC 50
    is received. Also disable it if the escape sequence specifies
    no font (Debian #760208).
    • 

    
  • improve fix for the fontsel menu entry from
    patch #304: because the recovery used
    the "current font", it would fail if one first selected a valid
    font, then an invalid font (Debian #760207).
    • 

    
  • correct an off-by-one in limit-check for
    ScrnLimitChar function (report by Egmont
    Koblinger).

    • 

    
  • amend resets for keyboard-type, pointer-mode and
    title-modes from xterm #305 changes to
    account for resource settings (Debian #751351).
    • 

    
  • modify printAttributes feature to include new SGR
    codes.
    • 

    
  • modify cursor show/hide logic to work with italic
    fonts.
    • 

    
  • do clipping and filling for a case with bitmap-fonts and
    italics when the font server returns only a "close" match
    (report/testcase by Egmont Koblinger).
    • 

    
  • adjust loop comparison for underlining to display
    underlines on 5x8 font as in patch
    #304 (Debian #750733).
    • 

    
  • amend fix for Freedesktop #15979 (Debian #750733).

Patch #306 -
  2014/06/03


  
    
    
  • fixes for display-errors in new SGR codes (report by Egmont
    Koblinger).
    • 
  


  
Patch #305 -
  2014/06/02


  
    
    
  • add xterm.appdata.xml (request by Richard
    Hughes). By the way, none of the released validators
    yet handle <licence> tags (or
    <metadata_license>, etc).
    • 

    
  • fix memory leaks in bitmap font-name caching.
    • 

    
  • other changes to hard-reset behavior:

      
      
        
    • reset keyboard-type on hard-reset.
      • 

        
    • reset pointer-mode (pointerMode) on
        hard-reset
      • 

        
    • reset title-modes (titleModes) on
        hard-reset
      • 

        
    • reset cursor-shape on hard or soft-reset
      • 

        
    • reset LEDs on hard-reset.
      • 

        
    • reset DECSACE on hard-reset.
      • 
      
    
    
    • 

    
  • reset bracketed-paste mode on hard-reset (suggested by
    Egmont Koblinger).
    • 

    
  • modify UTF-8 decoder to account for
    allowC1Printable resource.
    • 

    
  • revise getXftColor to ensure that its sequence
    number will not overflow in long-running sessions.
    • 

    
  • minor fix to selection to prevent hidden character from
    being returned in selection data (report by Egmont
    Koblinger).
    • 

    
  • add -sh to help-message.
    • 

    
  • amend check for incomplete fonts to always decide that a
    character is missing if the font lacks per-character metrics
    (prompted by Freedesktop #15979).
    • 

    
  • minor reorganization to implement “filler” SGR
    features. There are no established applications which rely upon
    these; some people find them amusing.

      
      
        
    • separate bits used to manage drawing state from
        attribute-bits.
      • 

        
    • implement SGR codes 2, 3, 9, 21 and their corresponding
        resets.
      • 

        
    • add configure option --disable-wide-attrs
        to disable the feature.
      • 
      
    
    
    • 

    
  • additional changes for ReGIS support (Ross Combs):

      
      
        
    • fix some arc drawing bugs and add support for pattern
        shading.
      •

Patch #304 -
  2014/05/03


  
    
    
  • add debugging check for parsing table entries, fixed a few
    inconsistencies.
    • 

    
  • handle utmp/utmpx strings consistently with new function
    that null-pads unused locations.
    • 

    
  • build-fix for imake configuration with FreeBSD 9 and later,
    to account for replacing utmp with
    utmpx.
    • 

    
  • improve handling of the fontsel
    (font-selection) menu item:

      
      
        
    • initialize the menu entry differently if the toolbar
        configuration is used, i.e., enabling it without attempting
        to use the current selection as a font name. Because of the
        way in which the toolbar is setup, this attempt usually
        failed, and would result in a warning.
      • 

        
    • if the menu action fails, e.g., no font can be loaded
        for the given selected name, then recover by resuming with
        the current font. Before, the recovery went to the default
        font. That was done to work around missing bitmap font in
        patch #276.
      • 
      
    
    
    • 

    
  • document OSC 119 in the control sequences listing
    (report by Egmont Koblinger).
    • 

    
  • modify special handling of XF86Paste or
    SunPaste keysyms (see patch
    #227) to use the standard shift/lock modifiers in case
    those are, for example, used in level 3 in an XKB file (patch
    by Matthieu Herrb).
    • 

    
  • configure macro updates:

      
      
        
    • drop the -no-gcc option from
        CF_INTEL_COMPILER
      • 

        
    • modify CF_XOPEN_SOURCE to suppress the check for
        defining _XOPEN_SOURCE on Solaris
      • 
      
    
    
    • 

    
  • reduce bss storage used for ReGIS/Sixel modules, as well as
    cleanup storage usage in other modules.
    • 

    
  • initial changes for ReGIS support (Ross Combs):

      
      
        
    • document control-sequences
      • 

        
    • separate ifdef's for sixel and color-register

  2014/03/06


  
    
    
  • improve check for /etc/shells to allow its
    entries to be symbolic links.
    • 

    
  • fix a regression in patch #302
    fixes relating to interaction of SHELL and
    XTERM_SHELL variables (Debian #740919).
    • 

    
  • improve manpage discussion of use of
    /etc/shells for validating the SHELL
    environment variable.
    • 

    
  • further improve the approximation for color map by ignoring
    bits which would not be applied by the rgb masks for the
    current visual (report by Joe Peterson).
    • 

    
  • add -report-colors to usage-message (report by
    Joe Peterson).
    • 
  


  
Patch #302 -
  2014/03/02


  
    
    
  • amend approximation for color map introduced in patch #277 to make that apply only to
    TrueColor (adapted from patch by Joe
    Peterson).
    • 

    
  • add -report-colors option, to show colors as
    they are allocated.
    • 

    
  • fix some gcc -Wcast-qual warnings.
    • 

    
  • correct app-defaults location for CentOS-4 in
    xterm.spec
    • 

    
  • improve check in minstall.sh for X manpage's
    section number; add sample dependencies for the relevant
    documentation package to packaging test-scripts (prompted by
    Novell #779474).
    • 

    
  • modify sample build-scripts for dpkg and rpm to ensure that
    vttests scripts are uncompressed and
    executable.
    • 

    
  • modify Perl scripts in vttests to use
    env to find Perl rather than relying on
    /usr/bin/perl This makes the sample scripts usable
    with NetBSD and other systems using pkgsrc.
    • 

    
  • amend check from patch #301 for
    valid shell to permit existing SHELL value to
    specify the shell; clarify the behavior in the manpage (report
    by Emmanuel Thomé).
    • 

    
  • amend change to wide-character processing from patch #257 to allow switching to/from UTF-8
    encoding if the utf8 resource was not set to
    “always” (report by Honza Maly).
    • 

    
  • fix incorrect free from patch #301
    changes, if explicit program without -e option is
    a valid shell (patch by Romain Francoise).
    • 
  


  
Patch #301 -
  2014/01/19


  
    
    
  • OSC 104 and 105 did not accept parameter to reset a
    specific color (patch by Egmont Koblinger).
    • 

    
  • add configure check for initgroups, and use
    that function to complement its use of setgid
    (prompted by patch by Miroslav Lichvar).
    • 

    
  • improve manpage description of scrollbar translations
    versus the vt100 translations (Debian #723573).
    • 

    
  • add a few paragraphs to manpage explaining the implications
    of xterm's reliance on X Toolkit for command-line parsing.
    • 

    
  • modify cursor-theme logic to check if the environment
    variable XCURSOR_THEME is set to a nonempty value
    before constructing a dummy them (prompted by similar check
    added in OpenBSD CVS).
    • 

    
  • add check for a case where TrueType bold font is missing a
    glyph where the non-bold font has it. Temporarily switch to the
    non-bold font to draw the glyph (report by David
    Demelier).
    • 

    
  • minor documentation fixes for ctlseqs.ms
    • 

    
  • only set SHELL environment variable to
    programs found in /etc/shells (prompted by
    patch/report by Al Poole).
    • 

    
  • build-fix, when --disable-wide-chars
    --disable-boxchar is used (prompted by patch by
    Andrey Panov).
    • 
  


  
Patch #300 -
  2013/12/03


  
    
    
  • amend workaround for Xcursor library from
    patch #298; the suggested solution for
    Debian #466704 fell afoul of a bug in Xcursor
    which treated an empty value for Inherits= as a
    valid theme—and resulted in a stack overflow due to
    unbounded recursion. Certain environments such as XFCE4 exposed
    the bug. A related report in Debian #531679 was closed without
    following the recommendation to limit stack recursion in this
    library (reported by Sergey V Dyatko, Debian #731269).
    • 
  


  
Patch #299 -
  2013/12/01


  
    
    
  • fix regression in line-drawing from patch #297 changes for NRCS exposed by change
    to assumeAllChars resource in patch #298 (report by Markus Waldeck).
    • 
  


  
Patch #298 -
  2013/11/27


  
    
    
  • quiet a warning about ambiguity when -h
    command-line option is parsed, since -help is used
    rather than the options mentioned in the message. This warning
    was caused by fixes in patch
    #272.
    • 

    
  • remove an extra check for keypad-mode which interfered with
    the patch #280
    modifyKeyboard feature for the numeric keypad
    (report by David Conners).
    • 

    
  • change default for assumeAllChars resource
    (Debian #725682). There are unresolved issues with Terminus
    fonts, e.g., Debian #722017.
    • 

    
  • add -report-fonts command-line option and
    reportFonts resource to optionally report the
    fonts which are loaded, and their metrics such as the number of
    missing glyphs.
    • 

    
  • work around Xcursor library to make
    pointerColor resource work as documented (Debian
    #466704, analysis by Vincent Lefèvre).
    • 

    
  • amend change from patch #297 for
    ASCII-equivalents to ensure that missing characters which
    happen to be double-width are padded to the expected number of
    columns. Also, correct the choice between normal/wide Xft fonts
    used when checking for missing characters (reported by WU Yue,
    Debian #728949, Gentoo #491334).
    • 

    
  • modify sixel-graphics drawing to account for scrollbar
    width (report by Mario Edelmann).
    • 

    
  • fix remaining issue with DECNRCM; the British
    character set was confused with ISO Latin-1 (report by Hayaki
    Saito).
    • 

    
  • build-fix for --disable-boxchars configure
    option.
    • 

    
  • updated configure macros, from ongoing work on lynx and
    ncurses.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #297 -
  2013/09/10


  
    
    
  • modify check for missing cells in bitmap font to work
    around terminus 10646 encoding, which is mostly missing, add
    assumeAllChars resource to provide the older
    behavior.
    • 

    
  • modify macros used to check for missing cells in bitmap
    fonts to pick up a long-overlooked improvement made to xfd in
    XFree86.
    • 

    
  • improve workaround for groff versus ASCII-equivalents;
    patch #185 had overlooked Xft
    configuration (reported by anonymous user on Arch Linux
    forum).
    • 

    
  • review/extend DECNRCM support (prompted by
    report by Hayaki Saito asking about the two "A" codes).

      
      
        
    • make pasting of DECNRCM data work by translating the
        pasted data into the selected encoding.
      • 

        
    • limit mode changes to VT220 and up.
      • 

        
    • ignore SCS for National Replacement Characters if
        DECNRCM is not set.
      • 

        
    • add tables and logic to decode SCS controls ending with
        "%" and one additional character. This expects the parsing
        of SCS to VT320.
      • 

        
    • also added parsing for SCS of DEC Supplemental and DEC
        Technical, which are for VT2xx and VT3xx respectively.
      • 

        
    • implement VT220 Multinational character set "GR" aka
        "DEC Supplemental Graphic".
      • 

        
    • DEC Technical character set based on vt100.net
        description.
      • 

        
    • implement Portuguese NRC.
      • 

        
    • provide for temporarily switching to/from NRC mode from
        UTF-8 mode when DECNRCM is set or reset.
      • 
      
    
    
    • 

    
  • minor fix to assert's found while testing examples from
    ttdoda's
    slrm-test1.txt.
    • 

    
  • modify DECLRMM to not update the cursor
    position (report by Iwamoto Kouichi forwarded by Hayaki
    Saito).
    • 

    
  • modify cursor-position report to take origin-mode into
    account (report by Hayaki Saito, see also iTerm2 pull
    request 129).
    • 

    
  • correct off-by-one comparison in when handling
    carriage-return at left margin (patch by Iwamoto Kouichi,
    forwarded by Hayaki Saito).
    • 

    
  • improve handling of faceName resource when a
    "size=" property is embedded in it, by using that size to
    replace the default faceSize resource. This lets
    xterm honor the other faceSize resources (report by Jens
    Schweikhardt).
    • 

    
  • improve OSC 52 selection-data by setting its timestamp
    to correspond to the most-recent event received by xterm, to
    ensure that calls to XtOwnSelect succeed even if
    the selection is manipulated solely through the keyboard
    (prompted by patch by Richard Tollerton).
    • 

    
  • change configure-script defaults for "luit" and
    "wide-chars" options to match the values used in the imake
    configuration, to lessen user surprise if they are accustomed
    to building xterm using imake(report by Andries E
    Brouwer).
    • 

    
  • improve the imake-related configuration's check if xterm is
    started in a locale that uses UTF-8 encoding. Before, this
    checked the locale settings only for "UTF-8", now it checks
    ignoring case for "UTF-8" and "UTF-8" (report by Andries E
    Brouwer).
    • 
  


  
Patch #296 -
  2013/07/10


  
    
    
  • improve experimental sixel feature (Ross Combs).
    • 

    
  • modify delimiter in configure macro used to add a library
    after a given library to avoid confusion with -Wl
    pass-through options to linker (NetBSD #48031).
    • 

    
  • fix quoting in expression used to trim extra libraries from
    patch #295 changes (report by Thomas
    Klausner).
    • 
  


  
Patch #295 -
  2013/07/06


  
    
    
  • adjust order of libraries to work around incomplete symbol
    resolution when using --as-needed option
    (ArchLinux #36047).
    • 

    
  • minor fix for plink.sh, for IRIX64.
    • 
  


  
Patch #294 -
  2013/07/05


  
    
    
  • add note in ctlseqs.ms for CPR response pointing out a
    potential point of confusion with the string sent by a modified
    F1 key (suggested by Bram Moolenaar).
    • 

    
  • improve plink.sh by checking if the linker
    supports the --as-needed option (suggested by
    David Philippi).
    • 

    
  • improve clearing for private mode 1049 when switching to
    the alternate screen (Debian #711758).
    • 

    
  • amend fix from patch #292 by
    removing now-unneeded chunk which introduced problem in
    selection (Debian #714527).
    • 

    
  • add definition to optionally override compiled-in class for
    xterm from makefile, needed for test-packages.
    • 

    
  • add configure option
    --enable-sixel-graphics
    • 

    
  • add experimental support for sixel graphics (Ross
    Combs).
    • 
  


  
Patch #293 -
  2013/05/27


  
    
    
  • modify sample xterm.spec to use newer icon
    • 

    
  • add configure option --with-icon-symlink to
    work around systems which map icon requests for to a single
    "xterm" icon, but neglect to install the icon needed for window
    decorations (report by H Merijn Brand).
    • 

    
  • improve parameterizing of sample xterm.spec
    • 

    
  • amend fix for printer from patch
    #280, removing a reset of the signal handler for
    SIGCHLD (report by Joe Julian).
    • 

    
  • set environment variable XTERM_FILTER if a
    locale-filter is used.
    • 

    
  • enable DEBUG logic when
    --enable-trace configure option is given.
    • 

    
  • improve description of initialFont,
    set-vt-font and set-tex-text in
    manpage (Debian #707899).
    • 

    
  • fix regression from patch #292;
    selecting a word that ended at the right margin without
    wrapping would not select the last cell (report by Christian
    Weisgerber).
    • 
  


  
Patch #292 -
  2013/04/25


  
    
    
  • add limit-check when double-click selects a word; if the
    saved-lines were scrolled back and the word selected wrapped at
    the screen's lower right corner, an assertion was triggered
    (patch by Taketo Kabe).
    • 

    
  • correct limit-check in unsaveEditBufLines,
    fixing a case where enlarging the terminal size could show a
    blank line where there actually is available text (patch by
    Bertram Felgenhauer).
    • 

    
  • add PasteControls feature to
    allowWindowOps which by default disallows pasting
    control characters other than formatting such as carriage
    return (discussion with Hayaki Saito).
    • 

    
  • fix typo in ctlseqs.ms for DECRQM response (patch by
    Emanuele Giaquinta).
    • 

    
  • update default shown in configure --help
    message for --with-terminal-id option (patch by
    Andres Perera).
    • 

    
  • rename script/preprocessor variables used for substituting
    the backarrowKey default value for consistency
    (patch by Andres Perera).
    • 

    
  • set umask to 077 before creating debugging-trace
    files.
    • 

    
  • add configure option --disable-openpty to
    control whether openpty() may be used in preference to
    posix_openpt().
    • 

    
  • improve workaround from patch #279
    for BSD systems which do not complete initialization until both
    sides of the pseudoterminal are opened, by preferring openpty()
    function over posix_openpt() when available (report by
    Christian Weisgerber).
    • 
  


  
Patch #291 -
  2013/02/26


  
    
    
  • add validity check for xterm widget parameter to
    AlternateScroll function, needed to handle wheel
    mouse events in the scrollbar area since patch #282 changes which introduced
    alternateScroll feature (Redhat #874327).
    • 
  


  
Patch #290 -
  2013/02/12


  
    
    
  • revert of patch #282 change was
    incomplete (report by Jim Reisert).
    • 

    
  • fix typo in manpage (report by Vincent Lefevre).
    • 
  


  
Patch #289 -
  2013/02/08


  
    
    
  • revert the patch #282 change which
    restored "lost" text after shrinking/growing the screen size.
    If the screen was updated between the two resizing operations,
    unexpected text might be shown at the end (report/testcase by
    Joe Peterson).
    • 

    
  • reverse the arrow-keys sent for
    alternateScroll to match the usage in browsers
    (suggested by Dieter Roelants).
    • 

    
  • modify mouse reports to consistently indicate motion events
    whether or not a button is pressed. Old behavior (since
    patch #127 modified encoding for wheel
    mouse) showed only that the button was released if no button
    had been pressed (report by Andy Koppe).
    • 

    
  • correct and improve behavior for SGR 1006 mouse protocol on
    button release in any-event mode. Initial implementation in
    patch #277 left internal state showing
    the last button pressed when reporting motion events. It now
    keeps track of all buttons which have been pressed and
    released, showing the lowest remaining button by number in the
    response (reports by Hayaki Saito, Andy Koppe).
    • 

    
  • fix inconsistency between TermColors and
    OscTextColors enums which interchanged values for
    tektronix cursor color and highlight foreground in control
    sequences in patch #225 (report/patch
    by Peder Stray).
    • 

    
  • fix inconsistent use of noreturn-attribute in
    Exit function which interfered with clang
    --analyze.
    • 

    
  • remove incorrect free used in computation of
    XTERM_SHELL variable, from Coverity fixes in
    patch #288 (FreeBSD #175782).
    • 

    
  • add --with-valgrind option to configure script
    for consistency with my other programs.
    • 

    
  • update table of ambiguous width characters in wcwidth.c
    based on Unicode 6.2.0
    • 

    
  • update table of combining characters in wcwidth.c based on
    Unicode 6.2.0
    • 

    
  • update precompose.c based on Unicode 6.2.0
    • 
  


  
Patch #288 -
  2013/01/09


  
    
    
  • fix a special case in ShowCursor where the
    foreground and background colors of the current position are
    the same. In that case, choose the further of the window's
    foreground and background colors for the cursor color.
    • 

    
  • modify alternateScroll feature added in
    patch #282 to use either
    CSI or SS3 according to the cursor
    keys application mode setting, to simplify using it in vi, etc.
    (suggested by Dietar Roelants).
    • 

    
  • revise manpage for resize to clarify the
    changes which resize may make to the terminal
    settings as well as to the terminal itself.
    • 

    
  • remove code such as struct ttysize, used for
    SunOS 3 and 4.
    • 

    
  • modify configure script and makefile to check for
    groff and suppress groff-specific rules if groff
    is not found.
    • 

    
  • modify ctlseqs.ms and makefile to work around bugs in
    grohtml which cause ".png" files to be truncated
    when producing html documentation.
    • 

    
  • modify suffix rules for "make docs" to make the names of
    the generated ".png" files predictable, helping to work around
    longstanding problems with this feature of groff—none of
    its releases work for all of xterm's tables..
    • 

    
  • correct typo in ctlseqs.ms for DECIC and DECDC; the
    character preceding the final "~" is an ASCII
    single-quote "'" rather than a space (report by
    Paul LeoNerd Evans).
    • 

    
  • update CF_GCC_VERSION macro, handling both Debian and
    Darwin.
    • 

    
  • improve configure script checks for the
    --with-desktop-category option. After patch #280 changes, if no value was given for
    this option, and no existing desktop files found for
    comparison, the incorrect "auto" value was passed into the
    generated desktop file (report by Julien Cristau).
    • 

    
  • modify sample build-scripts to disable check for
    imake due to code-rot in Xorg.
    • 

    
  • add -v command-line option to
    resize, reporting the same version string as
    xterm and the two shell-wrappers.
    • 

    
  • make name-transformation apply to other occurrences of
    resize, other manpages.
    • 

    
  • special-case the name-transformation in xterm's manpage in
    the NAME section so that the result works with
    makewhatis (report by Julien Cristau).
    • 

    
  • modify install-rules for manpages to put each program's
    respective transformed name into the header rather than
    xterm's.
    • 

    
  • remove deprecated files: proto.h, os2main.c
    • 

    
  • minor fixes based on Coverity scan, including:

      
      
        
    • correct caching of Atom value for the font menu's
        "Selection" entry.
      • 

        
    • ensure that utmp/utmpx calls do not depend upon
        trailing nulls in the ut_id and
        ut_line values.
      •

Patch #287 -
  2012/11/25


  
    
    
  • fix a case where in_put() loop could continue when it has
    found an X event rather than the pty, causing the pty-read to
    be delayed (patch by Balazs Kezes).
    • 

    
  • add option to pointerMode resource and
    corresponding control sequences to allow text-cursor to remain
    hidden if the pointer leaves/enters the window via accelerator
    keys. Ordinary motion within the window restores the pointer
    (prompted by patch by Balazs Kezes).
    • 

    
  • remove special case of modifiers for the
    Mode_switch and XK_ISO_Level3_Shift
    from patch #223. Verified that the
    conflict which this was intended to resolve does not happen for
    normal compose- or modeswitch-handling (prompted by patch by
    Balazs Kezes, Debian #638694).
    • 

    
  • modify the handling of focus-change events to ignore those
    whose detail is NotifyPointer, since those are
    sent in addition to focus-change events directed to the old/new
    windows having focus. In particular, this prevents the
    urgency-hint from being reset inadvertantly (prompted by patch
    by Balazs Kezes).
    • 

    
  • modify description of iconName in manpage to
    make it clearer that this resource does not specify the
    filename of an icon (discussion with Ian Collier).
    • 

    
  • modify iconHint resource to allow suppressing
    the built-in icon by setting this to "none" (discussion with
    Ian Collier).
    • 

    
  • make -iconic option work with the toolbar
    configuration.
    • 

    
  • correct initialization of window manager hints used to set
    the icon-pixmap. That detail from patch
    #282 overwrote state used to control the
    -iconic command-line option (report by Ian
    Collier).
    • 

    
  • fix paste64 feature for the case where the selection comes
    from the current terminal. The selection callback can happen
    after the reply is partly built, making it necessary to flush
    the reply-buffer to keep things in the proper order (report by
    Ailin Nemui).
    • 

    
  • reject command-line options which are longer than the
    options in xterm's table, to avoid mismatches (Redhat
    #875305).
    • 

    
  • correct attribution for patch #282
    changes.
    • 
  


  
Patch #286 -
  2012/10/29


  
    
    
  • fix minstall.in to work with "make docs" rule,
    so that patch number appears in the corresponding generated
    documentation.
    • 

    
  • modify minstall.in to keep the name shown in
    the heading consistent with any renaming, e.g., for
    test-builds.
    • 

    
  • check for misconfigured printerCommand
    resource on the first use, warn and disable it if it does not
    specify an executable command (Debian #691642).
    • 

    
  • improve check for window-manager name needed to establish
    usable default for activeIcon resource. This works around a
    scenario where gdm does incomplete cleanup,
    leaving window properties that refer to windows which no longer
    exist (Redhat #869959).
    • 
  


  
Patch #285 -
  2012/10/23


  
    
    
  • add/adapt FreeBSD ports files for test-building.
    • 

    
  • modify minstall.sh to use the patch-number and
    date in the manpage footer.
    • 

    
  • add check for failure to allocate the fg/bg colors at
    startup, e.g., misconfiguration. Work around by setting both to
    the default colors (suggested by Scott Bertilson).
    • 

    
  • amend change for patch #280 which
    added modifyKeyboard, to make
    modifyOtherKeys work (report by Ailin Nemui).
    • 

    
  • add query-colors.pl example for
    OSC 4.
    • 

    
  • correct mis-applied fix for minstall.sh (report by Miroslav
    Lichvar).
    • 
  


  
Patch #284 -
  2012/10/14


  
    
    
  • amend configurability changes for icons from patch #283, moving the new functionality to
    the iconHint resource to avoid conflict with
    existing uses of the iconName resource in the
    Shell widget (report by Emanuel Haupt).
    • 

    
  • fix documentation errata reported by Miroslav Lichvar:

      
      
        
    • correct manpage default for allowTcapOps
        (see patch #243
      • 

        
    • modify documentation for configure
        --enable-backarrow-key to match the script
        (see patch #280).
      • 

        
    • fix typo in minstall.sh in patch #283, which made the leading-cap
        "Xterm" become "xterm" (patch by Miroslav).
      • 
      
    
    
    • 

    
  • fix two typos in configure.in from patch #283 changes; one broke the
    --regex configure option (report by H Merijn
    Brand).
    • 
  


  
Patch #283 -
  2012/10/09


  
    
    
  • modify makefile and script to generate appropriate renaming
    s/xterm/xterm-dev/ for test-package's manpage.
    • 

    
  • improve makefile rules for installing/uninstalling pixmap
    files, to include the newer mini- and filled- variants.
    • 

    
  • clarify change in manpage regarding patch #282 change to always set a
    window-decoration icon, even if iconName is not
    set.
    • 

    
  • add a fourth flavor of window-decoration icons,
    "filled-xterm" for a monochrome xterm with filled
    interior.
    • 

    
  • use shape-mask to improve contrast of the window-decoration
    icons.
    • 

    
  • minor changes to icon colors to improve contrast on
    bright-mud backgrounds.
    • 

    
  • drop configure checks for memmove versus bcopy, and
    strerror function; all currently tested platforms support
    these.
    • 

    
  • cleanup configure macros, as done in byacc 20121003.
    • 

    
  • improve configurability of the built-in icon selectable via
    the iconName resource.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #282 -
  2012/09/28


  
    
    
  • improve configure check for
    XkbKeycodeToKeysym, fixing a regression on some
    older systems in the patch #280
    changes.
    • 

    
  • add clarification in manpage for
    alwaysBoldMode and veryBoldColors
    resources (prompted by Derek Martin question about using the
    former with TrueType fonts).
    • 

    
  • add alternateScroll resource and corresponding
    control sequences which modify the scroll-forw and
    scroll-back actions: when the alternate screen is
    displayed, wheel mouse up/down will send cursor keys (Debian
    #683942).
    • 

    
  • improve rendering for the case when a Unicode character is
    absent in the bold font but present in the normal font by
    temporarily falling back to the normal font (Debian #359006,
    Debian #408666).
    • 

    
  • provide configure option
    --enable-double-buffer and ifdef's to allow
    comparisons with/without double-buffering. The default uses
    normal buffering.
    • 

    
  • add feature to optionally scroll current page before
    clearing, controlled by resource setting
    cdXtraScroll (prompted by patch by Balazs
    Kezes):
    • 

    
  • integrated patches from Arch Linux forum posting (patches
    by Balazs Kezes):

      
      
        
    • modify reallocation limit of line-data when resizing
        screen so that "lost" text will be restored if the screen
        is first shrunk and then grown.
      • 

        
    • modify output to use double-buffering to reduce
        flicker.
      • 
      
    
    
    • 

    
  • modify scroll-lock action to handle
    on/off/toggle keywords like other actions. Previously the
    optional parameter was interpreted as an integer.
    • 

    
  • extend DECSCUSR to provide a way to set the
    cursor to a vertical bar (patch by Paul Bolle).
    • 

    
  • add -8, -c, -d and
    -u options to 88colors2.pl and
    256colors2.pl scripts. No current terminal
    emulator recognizes C1 controls while handling UTF-8
    encoding—see notes in patch #119
    and patch #109 regarding
    utf8controls—but the -u and
    -8 options are useful for demonstrating this
    point.
    • 

    
  • improve speed when changing color palettes using OSC
    controls by deferring repaint while followup controls might be
    additional color palette changes.
    • 

    
  • modify SGR 38 and
    SGR 48 to accept RGB index, matching the
    closest entry in xterm's palette.
    • 

    
  • extend SGR 38 and
    SGR 48 to accept colon as parameter separator
    (request by Paul LeoNerd Evans).
    • 

    
  • modify fullscreen action to allow it to toggle
    the full-screen mode rather than only set or unset it (prompted
    by Eeri Kask's suggestion to support
    _NET_WM_TOGGLE). This implementation does not yet
    use _NET_WM_TOGGLE.
    • 

    
  • add support for _NET_WM_STATE_MAXIMIZED_VERT
    and _NET_WM_STATE_MAXIMIZED_HORZ EWMH properties
    (suggested by Eeri Kask).
    • 

    
  • make fullscreen mode work with the tek4014 window. This
    change makes only the currently active window to be changed to
    fullscreen rather than changing both windows.
    • 

    
  • modify TekClear function to discard pending
    output before clearing the tek4014 display (patch by Kevin
    Ryde).
    • 

    
  • fix deleteIsDEL feature, broken in patch #280 changes (report by Mike Thornburg,
    forwarded by Jeremy Huddleston).
    • 

    
  • fix a special case of wrapping double-width characters
    (report/test-case by Ken Winstein).
    • 

    
  • add E3 extended capability to
    xterm-basic to match ncurses 20120728
    patch.
    • 

    
  • fix incorrect transformation of row-parameter for
    ClearCurBackground in patch
    #279 which caused incorrect painting in some scrolling
    scenarios (report by Chuck Silvers).
    • 

    
  • fix typo in manpage description of +maximized
    option (Paul Maier).
    • 

    
  • change default for configure option
    --with-xpm, turning it on unless requested
    otherwise.
    • 

    
  • add configure option --with-icon-name which
    can be used to override the default icon used in
    icon-themes.
    • 

    
  • extend activeIcon resource to provide
    default value which tells xterm to determine the
    window manager's name and automatically enable the feature for
    fvwm and window maker. The explicit true/false values can be
    used to override this behavior.
    • 

    
  • add "mini" xterm icon, which scales better than the
    standard xterm icon, e.g., for the gnome/kde "panel"
    feature.
    • 

    
  • extend iconName resource to search for icon
    named according to resource value and use that if found. If not
    found, use compiled-in pixmap. Both set the WM_ICON_NAME
    property which is used by various window managers, usually for
    window decoration.
    • 

    
  • updated autoconf patch, adding support for --datarootdir,
    which changes the default location of manpages.
    • 

    
  • further improved autoconf macros for configuring icons,
    from vile 9.8h
    • 
  


  
Patch #281 -
  2012/06/26


  
    
    
  • remove "$(srcdir)/" from install-icon rule to fix builds
    when --srcdir configuration option is used.
    • 

    
  • fix for configure script's search for icon file when it is
    not found in the current directory, e.g., when building out of
    tree (patch by Thierry Reding).
    • 

    
  • undo the XK_Home / XK_End change from patch #280 which broke the non-VT220 keyboard
    for those keys (report by H Merijn Brand).
    • 
  


  
Patch #280 -
  2012/06/24


  
    
    
  • add configure check to work around warning from
    desktop-file-install for "Encoding", noting that it emits
    deprecation warnings without providing its version
    information.
    • 

    
  • add configure option --with-icon-theme to tell
    xterm whether to install into an icon theme, defaulting to
    "hicolor" (Redhat #755206, Redhat #799614 and Redhat
    #804279).
    • 

    
  • change --with-icondir to look for "icons"
    directory rather than "pixmaps" by default. Add new option
    --with-pixmapdir to allow these two uses to be
    installed concurrently.
    • 

    
  • modify configure options --with-app-defaults
    and --with-icondir to accept "auto" as value to
    look for existing directory from well-known locations.
    • 

    
  • add missing codes for secondary DA response which tell the
    type of terminal as in the primary DA response.
    • 

    
  • update primary DA response for VT420 to include user
    windows and horizontal scrolling.
    • 

    
  • add modifyKeyboard resource to support
    keypad-modifier changes per request by Thomas Wolff.
    • 

    
  • add XK_Home / XK_End to editing-keypad checks
    • 

    
  • add back-tab key kB to termcap entries to
    match the terminfo.
    • 

    
  • update terminfo to match corresponding entries in ncurses,
    e.g., add XT and adjust sgr string
    for xterm-bold entry.
    • 

    
  • add configure options to predefine the most commonly
    customized resources for terminal-settings, use those to
    substitute into the manpage the corresponding compiled-in
    values: altSendsEscape, backarrowKey,
    backarrowKeyIsErase, deleteIsDEL,
    metaSendsEscape (Redhat #819588).
    • 

    
  • change default emulation level to VT420 (discussion with
    Ailin Nemui).
    • 

    
  • improve logic for DECSCL; patch
    279 partly enforced limitation of this to higher-level
    emulations. This patch finishes that change.
    • 

    
  • improve check for base of combining characters, preventing
    combination when cursor movement has intervened. Mosh's webpage
    gives two different examples of this, with other causes
    ascribed to the behavior.
    • 

    
  • modify IL/DL to set cursor to first column on row for
    better VT102/VT220 compatibility (prompted by code review of
    mosh).
    • 

    
  • separate state-table entries for DECSC/DECRC from the
    ANSI.SYS save/restore cursor, since the latter conflicts with
    DECSLRM when DECLRMM is enabled since patch #279 (report/analysis by Ailin
    Nemui).
    • 

    
  • fixes to avoid using SIGCHLD handler of main
    program in printer's subprocess (report by Joe Julian).
    • 

    
  • correct restore-parameter for mouse-modes from patch #279 changes.
    • 

    
  • add null-pointer checks to input-method caching added in
    patch #277 to fix a problem in the
    exposure code, when deselecting a window (report by Kriston
    Rehberg).
    • 

    
  • unset DESKTOP_STARTUP_ID environment variable
    to lessen confusion on the part of GTK applications which use
    the variable without checking it (report by John Little).
    • 
  


  
Patch #279 -
  2012/05/10


  
    
    
  • fill in missing cases in the save/restore modes feature
    (report by Thomas Wolff).
    • 

    
  • add check to ensure that combining characters are
    precomposed in the order given (report/analysis by Andries E
    Brouwer).
    • 

    
  • improve workability check for posix_openpt(), to take into
    account BSD systems which do not complete initialization until
    both sides of the pseudoterminal are opened (report by
    Christian Weisgerber).
    • 

    
  • amend fix for Debian #650291 in patch
    #277 changes to account for different data returned by
    vnc4server (Debian #670638).
    • 

    
  • add check in DECCRA operation to make copies of blinking
    text also blink by updating a line-level flag.
    • 

    
  • modify rectangle operations to work with DECOM.
    • 

    
  • modify DECSERA to use the current protected state rather
    than preserving it.
    • 

    
  • add precompose resource to allow storing
    character data in Normalized Form D as described in http://unicode.org/reports/tr15/
    (report/discussion with Andries E Brouwer).
    • 

    
  • modify CBT, other ISO-6429 controls which are used by VT520
    to work with DECOM.
    • 

    
  • add HPR and VPR controls, ISO 6429 cursor movement used in
    VT520.
    • 

    
  • remove "linux" restriction for IUTF8 ifdef in main.c
    (prompted by Matthew Dempsky posting on
    mailing.openbsd.tech).
    • 

    
  • implement the remaining VT420-level device status
    reports.
    • 

    
  • change DECXCPR to return page 1, rather than 0.
    • 

    
  • improve VT-level checks on reporting functions, such as
    DECXCPR.
    • 

    
  • change limit on decTerminalID to 525.
    • 

    
  • fixes to improve vttest vt52 screen when running as a
    VT420:

      
      
        
    • add checks for some VT2xx and up controls for
        consistency: DECSCL, S1C8T, S1C7T.
      • 

        
    • modify DECRQSS return for DECSCL to only return that
        when running as VT2xx and up.
      • 

        
    • when exiting from VT52-mode, resume in VT100 level
        rather than the level before starting VT52-mode.
      • 
      
    
    
    • 

    
  • implement DECLRMM, DECSLRMM and DECNCSM (prompted by
    discussions with Ailin Nemui and Paul LeoNerd Evans). This
    modifies several controls to obey top/bottom and left/right
    margins.
    • 

    
  • correct macro definition used for testing modes used in
    ANSI/DEC request-mode controls introduced in patch #262.
    • 

    
  • modify x_getlogin to check $LOGNAME and $USER
    before fallback to getlogin, so that user's choice
    for these variables can be carried forward to the xterm process
    (Debian #611487).
    • 

    
  • document DECSCUSR response for DECRQSS in ctlseqs.ms
    • 

    
  • add zIconTitleFormat resource to allow
    customizing the "*** " prefixed to the icon title when the
    zIconBeep feature is activated (request by Thomas
    Adam).
    • 

    
  • modify DECSCUSR to update the same internal variable as
    RM/SM 12, and document in manpage the two variables used for
    controlling blinking cursor (report by Paul LeoNerd
    Evans).
    • 

    
  • correct response data for DECSCUSR in reply for DECRQSS
    response, which had inverted the blink-value (reports by Ailin
    Nemui, Paul LeoNerd Evans).
    • 

    
  • add a null-pointer check in OkPasswd macro to
    fix a problem in resize with Fedora 17 and a
    serial console (report/patch by Daniel Drake).
    • 

    
  • add workaround for Mac OS X, which loses the window size of
    a pseudo-terminal when the tty device is opened
    (report/analysis by Egmont Koblinger).
    • 

    
  • updated configure check for workable
    posix_openpt versus grantpt, from
    luit fixes.
    • 

    
  • modify DECIC/DECDC/DECBI/DECFI implemented in patch #277 to enable them only in VT4xx mode
    and up (report by Ailin Nemui).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #278 -
  2012/01/18


  
    
    
  • correct initialization for eightBitMeta
    resource (FreeBSD #164101).
    • 

    
  • make special check for Darwin 9 (and lower) to not
    use posix_openpt (report by Christian Ebert).
    • 

    
  • minor fixes (adding ".ne" directives) to reduce the cases
    where groff's utility for generating images for tables dumps
    core. Most versions of groff (I've found 1.19.2 to be the most
    stable) dump core when attempting to report that there are too
    few lines on a page for a table to be shown.
    • 
  


  
Patch #277 -
  2012/01/07


  
    
    
  • remove special case for ISC pseudo-terminals which attempts
    to open the pty in two different ways.
    • 

    
  • move call to grantpt before asking utempter to
    add a record, to work with kFreeBSD which does not update the
    terminal's ownership until this point (Debian #652907).
    • 

    
  • document limitation of XIM interface in manpage (Debian
    #230787).
    • 

    
  • cleanup error reporting with new xtermWarning
    function.
    • 

    
  • add configure option --disable-selection-ops
    to make the new actions optional.
    • 

    
  • add four new actions for making the selection or data
    directly copied from the screen (prompted by discussion in
    Debian #637001, as well as report by Arjen van Tol):

      
      
        
    • exec-formatted
      • 

        
    • exec-selectable
      • 

        
    • insert-formatted
      • 

        
    • insert-selectable
      • 
      
    
    
    • 

    
  • add visualBellLine resource to allow
    visualBell to flash only the current line
    (prompted by patch by Gertjan Halkes).
    • 

    
  • add eightBitMeta resource to control the
    features which modify or interpret the eighth bit of a key when
    the meta modifier key is pressed (prompted by Debian
    #326200).
    • 

    
  • improve discussion of eightBitInput in the
    manpage (prompted by Debian #326200).
    • 

    
  • correct logic for alt-sends-escape action,
    overlooked when implementing altSendsEscape
    resource, which still used eightBitInput resource
    value.
    • 

    
  • add a workaround for XAllocColor(), which does
    not actually allocate "a read-only colormap entry corresponding
    to the closest RGB value supported by the hardware", but rather
    a rough approximation (Debian #650291).
    • 

    
  • undo parameter checks for RequestResize()
    added in patch #251 and amended in
    patch #270, because zeros also are
    special cases (report by John S Urban).
    • 

    
  • modify some test-scripts to use /bin/echo
    rather than the shell's possibly-builtin echo, to
    work around broken configuration on Mac OS X, i.e., neither
    honoring the option nor flagging an error.
    • 

    
  • add SGR 1006, as a better technical solution than SGR 1015:

      
      
        
    • the responses will not be confused with line-deletion
        and scrolling controls.
      • 

        
    • the button encoding is a little simpler, since it does
        not add an unnecessary 32 because the integer parameter
        does not have to be represented as a printable
        character.
      • 

        
    • the control responses for pressing and releasing a
        mouse button differ, allowing an application to tell which
        button was released.
      • 
      
    

      
    Besides these improvements, in discussion, it was noted
      that urxvt's implementation of 1005 is incorrect, relying
      upon a locale that provides UTF-8 encoding. In contrast,
      vttest demonstrates a correct decoding, independent of
      locale.
    
    
    • 

    
  • add support for urxvt SGR 1015 to address shortcoming of
    SGR 1005 with luit (patch by Egmont Koblinger).
    • 

    
  • add ISO and DEC controls useful for left/right
    scrolling.
    • 

    
  • add some changes for OpenBSD and MirBSD (adapted from patch
    by Thorsten Glaser):

      
      
        
    • disable search for non-Unix96 ptys.
      • 

        
    • fix a gcc warning in
        timestamp_filename
      • 

        
    • modify Imakefile to install xterm setgid
        to utmp.
      • 
      
    
    
    • 

    
  • add/use/prefer posix_openpt() for opening
    pseudo-terminal.
    • 

    
  • modify special errno handling case in ptydata.c from
    patch #158 to allow for the
    possibility that any platform may have special cases where
    "/dev/tty" is absent. For example, this can happen in a FreeBSD
    jail (patch by David Wolfskill).
    • 

    
  • add keyboard logic to map shift-tab into XK_ISO_Left_Tab,
    which is usually, not always, done by the X keyboard
    configuration.
    • 

    
  • portability fixes for some configure macros:
    CF_XOPEN_SOURCE
    • 
  


  
Patch #276 -
  2011/10/10


  
    
    
  • modify clipping limits for TrueType fonts to account for
    the scaleHeight resource setting, to work around
    another problem due to recent FreeType changes. In this case,
    the DejaVu Sans Mono set to pixelsize=13.5 is
    truncated because the font descent is reduced by FreeType to
    match an incorrect height metric (report by Adam Lee).
    • 

    
  • improve recovery when bitmap fonts are not installed, e.g.,
    so that switching font-sizes works for TrueType fonts.
    • 

    
  • modify lookup for XTERM_SHELL feature to allow
    relative pathnames.
    • 

    
  • modify abbreviation disambiguation check for command-line
    parameters to account for -geometry, whose
    parameter may begin with "+" or "-" (report by Scott
    Bertilson).
    • 
  


  
Patch #275 -
  2011/09/11


  
    
    
  • add ash, zsh to known shells for
    resize.
    • 

    
  • modify resize to reuse the logic from
    xterm which determines the actual logon-user's
    shell if $SHELL is not set.
    • 

    
  • revert the unsetenv("SHELL") added in patch #272.
    • 

    
  • an unsetenv("SHELL") added in patch #272 to help ensure that
    luit would get the user's shell consistently did
    not work as expected for cases where multiple names are in the
    password-file for a given uid. That was because changes in
    patch #157 to handle this situation
    did not take into account that repeated calls to
    getpwnam and getpwuid return a
    pointer to the same static buffer. Fixed the older logic to
    work as intended, by ensuring that the passwd-data from each
    call is stored separately (report by Paul Keusemann).
    • 

    
  • adjust ifdef's for putenv and
    unsetenv in case only one of those is provided on
    a given platform.
    • 

    
  • correct comparison used in ExposeContains
    macro from patch #274 changes, to
    handle window-dragging (patch by Todd Eigenschink).
    • 
  


  
Patch #274 -
  2011/09/05


  
    
    
  • portability fixes for cygwin: do not define
    SVR4, and work around nonstandard header
    location.
    • 

    
  • ifdef'd use of unsetenv from patch #273 changes to work with Solaris 9
    (report by Waldemar Rachwal).
    • 

    
  • modify logic for XtAppPending to merge
    adjacent Expose and ConfigureNotify
    events which are redundant (report by Edward McGuire).
    • 

    
  • fix an unneeded warning message when -r option
    is given.
    • 

    
  • remove a few redundant entries from table used for helping
    abbreviation-checking of command-line options, makes
    -geom work again after patch
    #272 changes as an abbreviation of
    -geometry.
    • 

    
  • add scaleHeight resource and command-line
    option -sh as workaround for some
    font-configurations broken by changes in FreeType 2.4.6 (report
    by Miroslav Hodak).
    • 

    
  • portability fixes for some configure macros:
    CF_FUNC_TGETENT, CF_XOPEN_SOURCE,
    CF_X_ATHENA_LIBS.
    • 

    
  • add configure option --with-freetype-config to
    improve selection over the plethora of configuration options
    which freetype has so far provided.
    • 

    
  • build-fix for configure --enable-load-vt-fonts
    when --enable-widec is not specified.
    • 

    
  • build-fixes for suppressing various features, needed after
    changes in patches 270, 271 and 272 (report by Brian
    Lindholm)
    • 
  


  
Patch #273 -
  2011/08/25


  
    
    
  • build-fix for out-of-tree "make docs" rule.
    • 

    
  • correct a typo in x_strdup, from patch #198 changes.
    • 

    
  • correct initialization for -e option, broken
    in patch #272 changes (report by
    Gabriele Balducci).
    • 

    
  • build-fix for out-of-tree builds to address
    minstall script changes in patch #272 (patch by Thierry Reding).
    • 
  


  
Patch #272 -
  2011/08/24


  
    
    
  • document limitation of Gtk in connection with
    xterm's -into option, in the manpage (Ubuntu
    #806969).
    • 

    
  • improve -into by checking for and using the
    size of the window within which xterm is embedded, overriding
    other clues.
    • 

    
  • modify logic for localeFilter resource to
    allow that to include command-line options of luit.
    • 

    
  • improve -into by checking for invalid
    window-id, and allowing hexadecimal/decimal/octal values.
    • 

    
  • improve keepSelection, adding the case where
    the highlighting is cleared, overlooked in patch #230 (patch by Marco Peereboom).
    • 

    
  • improve command-line parsing to make abbreviate options
    work consistently across xterm-specific versus standard X
    toolkit options, and report cases where an abbreviated option
    happens to be ambiguous. In particular, -d now
    works as an abbreviation for -display.
    • 

    
  • fix regression in command-line parsing introduced in
    patch #271 changes for Debian #629358,
    (Debian #637910).
    • 

    
  • split-out new termcap/terminfo building block
    xterm+kbs for configurability.
    • 

    
  • modify terminfo file to reflect changes in
    ncurses for xterm-16color and
    xterm-256color.
    • 

    
  • modify minstall.sh, etc., to reflect the
    default default class, $TERM and
    decTerminalID values.
    • 

    
  • reword resize manpage to reflect the fact that
    $TERMCAP is not set on all systems (patch by Alan
    Coopersmith).
    • 

    
  • work around combined Xaw6/Xaw7 package in DragonFlyBSD
    which omits the usual symbolic link to the preferred library
    name.
    • 

    
  • further improve build-fix for termcap systems by checking
    for some which are only partial implementations, e.g., termcap
    2.08 in CentOS 5.2
    • 
  


  
Patch #271 -
  2011/07/14


  
    
    
  • omit permissions adjustments to pty on exit except for
    pre-Unix98 ptys, since modern implementations handle this
    (report by Sean C Farley).
    • 

    
  • modify logic for switching fonts between UTF-8 and
    non-UTF-8 encoding to not merge the derivable bold-, wide- and
    widebold values from the VT100 fonts. Also suppress warning
    when not using UTF-8 fonts if wide- and widebold-fonts cannot
    be derived or otherwise loaded (report by Werner
    Scheinast).
    • 

    
  • modify menu-creation to suppress entries which will never
    be used in the current configuration, rather than simply
    disabling them.
    • 

    
  • add resource printModeImmediate and menu item
    to allow print of screen plus saved lines to a file.
    • 

    
  • add menu item to allow runtime enable/disable of the
    printFileOnXError feature.
    • 

    
  • append a timestamp to filename used in
    printFileOnXError feature, and restrict its
    permissions (request by Vincent Lefevre).
    • 

    
  • add a check when cancelling cursor-blinking, in case the
    cursor is blinked off. Fix so that the cursor is repainted
    without waiting for other events, e.g., keypress (report by
    Ailin Nemui).
    • 

    
  • add configure --with-app-class option, to
    simplify building "xterm-dev" packages with filenames that do
    not conflict with conventional "xterm" packages.
    • 

    
  • corrected logic flow for DECSCL, which prevented the
    updated operating level from being reported via DECRQSS (report
    by Ailin Nemui).
    • 

    
  • corrected default for brokenStringTerm
    resource to match manpage.
    • 

    
  • add vttests/dynamic.pl
    • 

    
  • add runtime check for locale not supported by X libraries,
    and fallback to XA_STRING in this case (request by Bryan
    Henderson).
    • 

    
  • fix a special case in configure script after no FreeType
    libraries are found. The script was proceeding to check for a
    usable configuration.
    • 

    
  • add xterm+tmux building block to terminfo
    (adapted from changes proposed by Ailin Nemui and Nicholas
    Marriott).
    • 

    
  • improve discussion of faceName resource in
    manpage (adapted from suggestions by Jens Schweikhardt).
    • 

    
  • correct mapping of shifted up/down cursor-keys in termcap
    function-keys mode, i.e., resource
    tcapFunctionKeys (patch by Gertjan Halkes).
    • 

    
  • update AIX case in CF_XOPEN_SOURCE configure
    macro to add release 7.x.
    • 

    
  • modify ifdef's in xterm_io.h for
    __hpux to force that to use the hacked SYSV
    support in that file. This fixes a problem with a non-blocking
    socket call (patch by Paul Lampert).
    • 

    
  • improve filtering of desktop category scanning, to exclude
    XFCE.
    • 

    
  • modify configure script to work with systems that have both
    ncurses (or other terminfo) as well as a real termcap library,
    e.g., Slackware (report by Andrew Watts).
    • 

    
  • modify configure script to work around special case where
    user's environment adds compiler flags to the CC
    variable (prompted by report by Paul Lampert).
    • 

    
  • amend change for Debian #110226 so that "-h" or "-v"
    options cause an exit, rather than simply printing to stdout
    while the window is displayed (Debian #629358).
    • 

    
  • add response for DECRQSS which gives the
    setting for DECSCUSR.
    • 

    
  • modify AllocateTermColor() to handle
    XtDefaultForeground and
    XtDefaultBackground, which are not recognized by
    XParseColor. For example, this fixes the use of
    OSC 112 when no explicit cursor color was set (report by
    Ailin Nemui).
    • 

    
  • handle special-case of KeyPress translated to
    popup-menu action (Ubuntu #756273).
    • 
  


  
Patch #270 -
  2011/04/26


  
    
    
  • build-fix, e.g., for using imake on platforms
    which use the termcap library.
    • 

    
  • modify utf8 resource to accept a name.
    • 

    
  • mention default for fontWarnings in manpage
    (report by Werner Scheinast).
    • 

    
  • split "UTF-8" menu entry into "UTF-8 Encoding" and "UTF-8
    Fonts" (prompted by discussion with Werner Scheinast).
    • 

    
  • gray-out font-menu entries when a font fails to load, e.g.,
    a bitmap font is not installed.
    • 

    
  • improve behavior when there is no app-defaults file:

      
      
        
    • set the toolBar resource to false
      • 

        
    • gray-out the font menu entries where no resource is
        found.
      • 
      
    
    
    • 

    
  • add configure option --with-desktop-category
    to allow customization of the ".desktop" files.
    • 

    
  • build-fix for the install-desktop
    makefile-rule, when the source/build directories differ (patch
    by Loïc Minier).
    • 

    
  • add menu entry and corresponding resource which can be used
    to suppress all bold-fonts (discussion with Jan
    Engelhardt).
    • 

    
  • make internal line-size value consistent with allocated
    sizes of character and related arrays to ensure that bulk
    copying of line data, e.g., in scrolling, accounts for the
    padding used for pointer alignment (adapted from patch by
    Rajesh Mandalemula, also reported by Ali Bahar).
    • 

    
  • widen ifdef for screen-resizing logic from patch #176 changes to send
    SIGWINCH to process group to include any system
    supporting ioctl(*,TIOCGPGRP,*) (prompted by
    linux-specific patch in OpenSUSE rpm package).
    • 

    
  • add printModeOnXError and
    printFileOnXError resources, which allow the user
    to specify that xterm will write the contents of its screen to
    a file if it is exiting due to an X error (Debian
    #280457).
    • 

    
  • restore logic that made reverse-video apply to the
    scrollbar's foreground/background, broken in patch #158 (report by Bryan Ischo).
    • 

    
  • amend some of the window operations parameter-checks added
    in patch #251 for the push/pop title
    feature, to allow the parameters used for window resizing to be
    -1's, which makes the corresponding values ignored rather than
    using the window's maximum width/height (report by Noah
    Friedman).
    • 

    
  • correct order of initialization for
    translations vs fullscreen resources
    to enable a special case which omits the Alt-Enter translation
    when fullscreen is disabled (Debian #612978).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #269 -
  2011/02/19


  
    
    
  • build-fixes for imake (report by Heiko
    Berges).
    • 

    
  • modify autoconf macro CF_PKG_CONFIG to work with
    cross-compile environments (patch by Thierry Reding).
    • 

    
  • modify MapToColorMode() to favor bold over
    underline, matching the precedence used before patch #252 (report/analysis by Nicolas
    George).
    • 

    
  • add omitTranslation resource, which can be
    used to suppress the default translations for these features:

      
      
        
    • fullscreen
      • 

        
    • scroll-lock
      • 

        
    • shift-fonts
      • 

        
    • wheel-mouse
      • 
      
    
    
    • 

    
  • make the fullscreen feature configurable (Debian #612978)

      
      
        
    • add it to the configurable list
        disallowedWindowOps.
      • 

        
    • add command-line option -fullscreen to
        allow the feature to be enabled at startup.
      • 

        
    • add resource fullscreen to control whether
        the feature is active or may be enabled.
      • 
      
    
    
    • 

    
  • modify probe_netwm_fullscreen_capability for
    64-bit machines. Contrary to XGetWindowProperty
    manpage, that function returns 32-bit data packed as
    long's.
    • 

    
  • eliminate copy of name resource, which was
    otherwise used only to give the terminal-description name for
    the tcap-query feature. Use the actual $TERM value
    instead, as derived from termName resource,
    etc.
    • 

    
  • eliminate an old inconsistency with error messages, some
    used the -name option, while others used
    argv[0]. The latter is now used consistently.
    • 

    
  • improve configure check for rpath-hack, to improve builds
    on systems where gcc will not search /usr/local/lib, etc.
    • 

    
  • build-fix for Xaw3d configuration (report by H Merijn
    Brand).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #268 -
  2011/02/10


  
    
    
  • fix an inconsistency of the "Enable Reverse Video" checkbox
    in the VT Options menu. This also removes a special case added
    in patch #217 which limited the effect
    of the reverseVideo resource (Debian
    #603808).
    • 

    
  • amend decoding of misformed UTF-8 sequences to avoid
    absorbing valid characters as documented in Unicode 6.0 section
    3.9 (report by Keith Winstein).
    • 

    
  • do not set urgency hint when window already has focus
    (patch by Dimitrios Christidis).
    • 

    
  • amend extended mouse-coordinate mode from patch #262 changes to include the Cb
    button-code, which also may be greater than 127 (report by
    Ailin Nemui).
    • 

    
  • ensure that underline-cursor is visible when an application
    happens to set the background color (report by Christian
    Weisgerber).
    • 

    
  • add feature for 
    full-screen toggling using either Alt-Enter or a menu
    selection (integrated patch by Dave Simmons).
    • 

    
  • add missing logic to handle reallocation of FIFO index for
    the "UTF-8" menu entry (report by David Holland, NetBSD
    #44344).
    • 

    
  • add makefile rules docs-ctlseqs,
    docs-xterm, etc.
    • 

    
  • correct typo in description of DECRPM in control sequences

    • 
  


  
Patch #267 -
  2010/11/20


  
    
    
  • minor formatting changes to ctlseqs.ms to simplify a script
    which extracts the feature information. See the results in
    
    Comparing versions, by counting controls in the xterm
    FAQ.
    • 

    
  • add docs-clean makefile rule.
    • 

    
  • add copy-selection action (request by Timo
    Juhani Lindfors, Debian #588785).
    • 

    
  • trim leading/trailing blanks from string used for
    "Selection" font-menu data.
    • 

    
  • trim leading/trailing blanks from color resource
    values.
    • 

    
  • configure script improvements:

      
      
        
    • add workaround for removal of X11 dependency from Xt's
        package file (report by Robert Hooker).
      • 

        
    • add workaround for removal of fontconfig dependency
        from Xft's package file (report by Jeremy Huddleston).
      • 

        
    • add workaround for removal of Xmu dependency from Xaw's
        package file (report by Jeremy Huddleston).
      • 

        
    • improve workaround in CF_X_TOOLKIT macro,
        checking for other possible packages where Xt's
        dependencies may be given.
      • 

        
    • prefer ${name:=value} to
        ${name-value}, since recent bash changes break
        legacy support for that feature.
      • 
      
    
    
    • 
  


  
Patch #266 -
  2010/10/24


  
    
    
  • add rpm and dpkg scripts, for testing.
    • 

    
  • more fixes for Debian #600707 (report by Cyril
    Brulebois).
    • 
  


  
Patch #265 -
  2010/10/22


  
    
    
  • fix a regression in fontname logic from patch #263 changes (Debian #600707, reported
    by Vincent Lefevre).
    • 

    
  • revert modification of any-event/any-button protocol from
    patch #263 changes. It interferes with
    selection using a shifted mouse button (reports by Neil Bird,
    Bram Moolenaar).
    • 
  


  
Patch #264 -
  2010/10/14


  
    
    
  • replace a null-pointer check with check for empty string in
    xtermOpenFont, to eliminate a warning message from
    patch #263 changes.
    • 

    
  • build-fix for patch #263 when
    toolbar is not configured (patch by Chris Clayton) (reports by
    Robby Workman, David Wood).
    • 
  


  
Patch #263 -
  2010/10/13


  
    
    
  • corrected initialization of "misc" resource values, to
    ensure that xterm has allocated a copy of strings which may not
    have been malloc'd by the X library (Debian #600129).
    • 

    
  • modify handling of any-event/any-button mouse protocol; it
    now is active with any combination of key-modifiers.
    • 

    
  • add debugging feature showWrapMarks, which
    marks lines which xterm knows are wrapped, showing where a
    double-click will select past the end of a line.
    • 

    
  • build-fix to address change in include-guards for
    Xlib.h in ongoing Xorg edits (patch by Jeremy
    Huddleston).
    • 

    
  • improve pointerMode by continuing to watch for
    motion events after mouse tracking is disabled if the pointer
    is hidden (Debian #594856).
    • 

    
  • further extend initialization for active-icon font to check
    if the font was not loaded succesfully, to retry with
    font1, or as even (if TrueType fonts are used) to
    use a TrueType font. The retries are to help with cases as in
    patch #241 where the bitmap fonts are
    not available.
    • 

    
  • fix special case of active-icon used when TrueType font is
    specified for the xterm window, from patch
    #261 change. In that case, the default font's size was used
    for layout of the active icon's window (Debian #591265).
    • 
  


  
Patch #262 -
  2010/8/30


  
    
    
  • fix a case where changing the cursor color via escape
    sequences did not immediately update the screen (report by
    Andreas Wagner).
    • 

    
  • implement ANSI and DEC request-mode control sequences. The
    latter includes the xterm-specific private modes such as the
    mouse mode. The feature is ifdef'd with the rectangle
    operations since its decoding overlaps that feature.
    • 

    
  • correct typo in ctlseqs.ms for response of OSC 21 (patch by
    Kevin Schoedel).
    • 

    
  • improve discussion of mouse tracking in ctlseqs.ms
    • 

    
  • increase an array limit used in reporting mouse events
    (report by Ryan Johnson).
    • 

    
  • add extended mouse-coordinates mode, allowing up to
    2015x2015 windows, using UTF-8 encoding (patch by Ryan
    Johnson).
    • 

    
  • modify manpage hyphens to conform with 
    Debian.
    • 
  


  
Patch #261 -
  2010/6/28


  
    
    
  • fix regression in renderFont logic, from
    patch #260 changes (report by Joseph
    Quinsey).
    • 
  


  
Patch #260 -
  2010/6/20


  
    
    
  • modify plink.sh to work around problem linking
    to recent PCRE libraries.
    • 

    
  • extend renderFont resource to allow deferred
    switch to TrueType fonts without affecting existing resource
    settings (Debian #585620).
    • 

    
  • modify configure macro CF_X_TOOLKIT to work around omission
    of ICE library from ".pc" file (report by Miroslav
    Lichvar).
    • 

    
  • change configure script default for
    --enable-broken-st i.e., the
    brokenStringTerm feature) to normally enable it.
    If the corresponding resource is enabled, this feature
    eliminates an apparent freeze of xterm when sending mis-encoded
    data to the screen (Debian #584801).
    • 

    
  • document in manpage some actions which were overlooked:

      
      
        
    • readline-button
      • 

        
    • scroll-lock
      • 

        
    • set-8-bit-control
      • 
      
    
    
    • 

    
  • undo a change to limit-check in ScrnRefresh in
    patch #257, which broke
    fastScroll feature (Debian #584841).
    • 

    
  • modify handling of brokenLinuxOSC and
    brokenStringTerm to also sound the bell.
    • 

    
  • add control/D and control/Q to controls which will cause
    early exit from control string per
    brokenStringTerm resource.
    • 

    
  • improve documentation of brokenStringTerm
    resource in manpage.
    • 
  


  
Patch #259 -
  2010/6/5


  
    
    
  • modify configure check for luit to include new
    aliases for the program (xterm-filter and
    bluit).
    • 

    
  • add workaround in xtermClearLEDs() to account
    for Xkb's override, making vttest's LED demo reset the scroll
    lock.
    • 

    
  • filter out client-message events when deciding whether to
    hide cursor, e.g., when using SCIM (patch/report by anonymous
    user).
    • 

    
  • improve description of -bd option in manpage
    (report by Guy Daniel Clotilde).
    • 

    
  • modify configure checks for PCRE and other libraries to use
    pkg-config, if available.
    • 

    
  • amend change from patch #252, to
    take veryColorColors resource into account when
    checking colorBDMode resource for TrueType fonts
    (report by anonymous user).
    • 

    
  • add vttests/query-fonts.pl script for
    demonstrating the OSC 50 font query.
    • 

    
  • improve manpage discussion of Scroll Lock feature.
    • 

    
  • improve configure macros CF_GCC_VERSION and
    CF_GCC_WARNINGS.
    • 

    
  • fix warnings for "clang --analyze".
    • 

    
  • change default for allowScrollLock resource to
    false, noting that the supposedly unused key has
    been useful for various rebindings (Debian #580946).
    • 
  


  
Patch #258 -
  2010/5/1


  
    
    
  • add pointer-checks in ScrnRefresh to fix a
    case in rapid scrolling where an empty record is fetched from
    the scrollback FIFO.
    • 
  


  
Patch #257 -
  2010/4/22


  
    
    
  • correct ctlseqs.ms description of OSC 17 and OSC 19 (patch
    by Emanuele Giaquinta).
    • 

    
  • corrected logic for menuLocale resource; the
    setlocale function returns the original locale
    only when querying.
    • 

    
  • improve filtering of translations resource, narrowing the
    scope of the alwaysUseMods to address only the
    translations that would cause a key to be sent to the host
    (report by Andrew Gaylard).
    • 

    
  • change default value of menuLocale resource to
    "C", to work around longstanding Xorg
    bug.
    • 

    
  • modify handling of scrollKey feature to ignore
    XON/XOFF keys.
    • 

    
  • implement scroll-lock feature.
    • 

    
  • revise memory allocation in UTF8toLatin1() to fix an
    out-of-bounds index (Mandriva #54531).
    • 

    
  • compute value for first wide-character rather than assuming
    it is 256, fixes problem with -cjk_width
    introduced in patches 242 and 249 (report by Thomas Wolff).
    • 

    
  • improve configure script:

      
      
        
    • corrected check for _XOPEN_SOURCE for
        OpenSolaris.
      • 

        
    • when possible, add rpath option for libraries in
        unusual places
      • 

        
    • add configure option --disable-rpath-hack
        to control whether the rpath option can be added.
      • 
      
    
    
    • 

    
  • modify AllocateTermColor() to separate
    initialization from control sequences, fixing problem from
    patch #254 changes where enabling
    allowSendEvents resource prevents setting cursor
    color on command-line (Debian #572928).
    • 

    
  • amend logic from patch #185 to not
    reallocate cell-array if processing
    ESC % G to switch from UTF-8 if already
    in ISO-8859-1 character set (report by Michael Koehne).
    • 

    
  • fix to avoid calling XmuInternStrings() with
    zero count (report by Johan Bockgård).
    • 

    
  • fix build when --disable-ansi-color configure option is
    used.
    • 

    
  • fix build when neither OPT_TCAP_QUERY or OPT_TCAP_FKEYS is
    defined (patch by Matthieu Herrb)
    • 
  


  
Patch #256 -
  2010/3/6


  
    
    
  • add TerminalEmulator to desktop category files.
    • 

    
  • modify sinstall.sh to ignore the "." appended
    to permissions by selinux.
    • 

    
  • change app-defaults organization, installing UXTerm-color
    and KOI8XTerm-color for consistent behavior regarding
    customization: color (prompted by discussion
    in Ubuntu #421261).
    • 

    
  • fix typo in minstall.sh from patch #255 changes, and add case for
    /var/run needed for full path of utmp (report by
    Julien Cristau).
    • 

    
  • minor fix to xterm manpage, remove a comment stating that
    margin bell can be changed via the VT Options menu. That was
    replaced in patch #225
    • 

    
  • add a "docs" rule to makefile.
    • 

    
  • fix initialization of Atom used for XkbBell
    feature from patch 243 changes. Unlike
    the other calls to XInternAtom(), in this case the
    flag telling X to create the Atom was unset (patch by Chris
    Adams).
    • 
  


  
Patch #255 -
  2010/1/21


  
    
    
  • rename install.sh to install-sh
    in case suffix-rules might interfere.
    • 

    
  • extend range for convertToUTF8 function to
    full 31-bits, to use with printing, etc.
    • 

    
  • improve manpage by checking for actual locations of
    utmp/wtmp files (Debian #562640).
    • 

    
  • modify configure macro CF_XOPEN_SOURCE to remove -D's
    before adding the same name rather than relying on -U's, to
    reduce redefinition warnings for some platforms that have
    conflicting definitions in headers.
    • 

    
  • correct logic used to switch to alternate screen using
    FIFO-lines configuration (Debian #565772).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #254 -
  2010/1/6


  
    
    
  • add a configure-check to eliminate install-ti
    rule from Makefile when the system has no tic (terminfo
    compiler) program. This lets one use the
    install-full rule more consistently.
    • 

    
  • amend change to WriteText() function in patch #252 to take into account the
    colorAttrMode resource (report by Krzysztof
    Kotlenga).
    • 

    
  • document titleModes resource in manpage, added
    in patch #252.
    • 

    
  • modify tcap-query table entries for shifted up/down cursor
    keys to match ncurses convention.
    • 

    
  • improve lookup of termcap-query data, allowing for
    duplicate keycodes versus missing entries.
    • 

    
  • add control sequence which can be used to modify the
    terminal data used for the termcap-keyboard.
    • 

    
  • improve portability of tcap-query feature, using terminfo
    functions in preference to termcap on systems having
    terminfo.
    • 

    
  • improve font-setting/querying control
    (OSC 50):

      
      
        
    • when TrueType font is selected, the TrueType
        faceName will be set, rather than the bitmap
        font.
      • 

        
    • when TrueType font is selected, querying returns the
        name of the TrueType font.
      • 

        
    • querying a font recognizes the relative-font convention
        that setting a font could use.
      • 
      
    
    
    • 

    
  • add menu-entry for allowColorOps.
    • 

    
  • add new resources for fine-tuning menu entries:
    allowColorOps, disallowedColorOps,
    disallowedFontOps and
    disallowedTcapOps.
    • 

    
  • correct logic for disabling the "TrueType Fonts" menu item;
    it was not ensuring that the faceName resource
    value was non-empty.
    • 

    
  • implement VT520-style controls DECSMBV and
    DECSWBV for setting the margin- and warning-bell
    volume.
    • 

    
  • fix a minor error from patch #243
    which made the zIconBeep feature use a minor-error tone rather
    than an informational tone.
    • 

    
  • add a null-pointer check for the case where
    renderFont resource is true, but
    faceName resource is unset, used in logic to strip
    "xft:" prefix from patch #251 changes
    (patch by Michael Riepe).
    • 

    
  • add special case to configure CF_XOPEN_SOURCE macro to use
    extensions on Darwin (patch by Dennis Preiser).
    • 

    
  • improve configure checks for regular expressions header and
    library
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #253 -
  2009/12/10


  
    
    
  • add a null-pointer check in getPrinterFlags()
    per changes in patch #252.
    • 

    
  • add a null-pointer check, needed in UTF-8 mode for Xft
    fonts after changes in patch #252
    (patch by Alan Coopersmith).
    • 

    
  • correct size when clearing struct for tek4014 (patch by
    Jochen Voss).
    • 

    
  • parenthesize expression in MoreRows macro,
    fixing a limit check added in patch
    #251 (Debian #560039).
    • 
  


  
Patch #252 -
  2009/12/7


  
    
    
  • modify title-querying logic to support retrieval of titles
    encoded using UTF-8.
    • 

    
  • add new "title-modes" control sequence for controlling
    whether window/icon titles can be set or queried using UTF-8,
    optionally encoded in a hexadecimal string.
    • 

    
  • use mkdir -p rather than
    mkdirs.sh (prompted by discussion of mawk by
    Aleksey Cheusov).
    • 

    
  • add appropriate copyright/license notices to the bulk of
    files lacking same, and modify to use identical terms in others
    which used different wording. The main exceptions are the files
    contributed by Markus Kuhn, who appears to prefer public domain
    distribution, noting that I have modified/improved several of
    these without changing the terms of distribution (request by
    Jari Aalto).
    • 

    
  • add control sequences for resetting the "dynamic" colors to
    their default values.
    • 

    
  • add control sequences for resetting the "special" colors to
    their default values.
    • 

    
  • add control sequences for setting the "special" colors such
    as colorBD (bold).
    • 

    
  • add overlooked case for setting highlight foreground color
    with the dynamic-colors control.
    • 

    
  • add OSC 104, for resetting ANSI/16/88/256
    colors to default.
    • 

    
  • reset ANSI/16/88/256 colors to default in soft/hard reset
    functions.
    • 

    
  • strip "xft:" prefix from faceName and
    faceNameDoublesize resource values,
    • 

    
  • add DECSCUSR (discussion with Andy
    Koppe).
    • 

    
  • add check/warning on failure to load font, to see if the
    name looks like an Xft pattern rather than XLFD. This can
    happen if someone happens to modify their X resource settings
    for programs that read data from xterm's namespace.
    • 

    
  • modify handling of print and
    print-everything actions to allow the various
    printer flags to be overridden by supplying parameters.
    • 

    
  • add resource printerNewLine (request by Ovidiu
    Gheorghioiu).
    • 

    
  • minor cleanup, finish using TScreenOf() and
    TekScreenOf() macros introduced in patch #224.
    • 

    
  • improve checks in ShowCursor/HideCursor to get the
    background color, particularly when
    highlightReverse resource is used (reports by Jan
    Engelhardt, Christian Weisgerber).
    • 

    
  • correct checkVeryBoldAttr to omit comparison
    of foreground color to special color values used for
    color<XX> resources (report by Jan
    Engelhardt).
    • 

    
  • make colorBDMode and colorULMode
    resources work with TrueType configuration (report by Jan
    Engelhardt).
    • 
  


  
Patch #251 -
  2009/11/11


  
    
    
  • add window-ops controls to push/pop icon and/or window
    labels on a stack.
    • 

    
  • minor fixes to align termcap file with terminfo.
    • 

    
  • add resource disallowedWindowOps, to allow
    fine-tuning of features to suppress with the
    allowWindowOps resource (prompted by discussion
    with Bram Moolenaar).
    • 

    
  • add makefile rules for resize-manpage to pdf, etc.
    • 

    
  • further improve limit-checks in select/paste (Mandriva
    #54531).
    • 
  


  
Patch #250 -
  2009/10/13


  
    
    
  • add check and error-message for fonts that have no
    printable values in the ISO-8859-1 range (Debian #542434).
    • 

    
  • some compiler-warning cleanup, in particular workaround for
    defective implementation of gcc's attribute warn_unused_result
    (report by Bram Moolenaar).
    • 

    
  • improve estimate of single-column width for packed TrueType
    fonts by ignoring extents for codes 127 and 159.
    • 

    
  • improve line-drawing for TrueType fonts which happen to
    have defined glyphs which are not line-drawing in
    0..31 by assuming they're not, and just checking the existence
    of the Unicode codepoints. This makes it more likely that the
    user can override a misconfigured font using the "Line-Drawing
    Characters" menu entry.
    • 

    
  • limit minimum cell-width for packed font to maximum-advance
    reported by Xft. Some fonts are wider than that, even in the
    Latin-1 range (Debian #550497).
    • 

    
  • add list of direct-contributors in "THANKS" file.
    • 

    
  • stylistic changes to this file to help scripted extraction
    of list of contributors.
    • 

    
  • correct off-by-one in okPosition fix from
    patch #249 limit-checks which
    prevented double-click selection on the bottom line of the
    screen (reports by Rajeev V. Pillai, Debian #550368).
    • 

    
  • add -q option to
    vttest/256colors2.pl and
    vttest/88colors2.pl to demonstrate bulk
    initialization of color palette.
    • 

    
  • improve the workaround from patch #188 by enabling
    resources for the 88-color model.
    • 

    
  • document in xterm manpage the limited availability of
    resources color16 to color255 as
    noted in patch #188 (Ubuntu
    #438850).
    • 
  


  
Patch #249 -
  2009/10/1


  
    
    
  • change default for allowWindowOps resource to
    false. 
    
    • 

    
  • add limit-checks for result of visual_width() function,
    needed from patch #242 and exposed by
    #244 changes (Debian #548321).
    • 

    
  • improve limit-checks in select/paste.
    • 

    
  • fix a remaining bug from patch
    #230 changes for displaying multi-column characters in a
    proportional font (report by Chris Jones).
    • 

    
  • add new resource forcePackedFont and menu entry "Packed
    Font" to control whether to use the font's minimum (default) or
    maximum width when those differ. The workaround which xterm
    uses to accommodate proportional fonts is not necessary with
    certain fonts such as unifont which happen to store a mixture
    of multicolumn glyphs (report by Chris Jones).
    • 

    
  • fix an (old) bug which did not restart the timer for
    blinking text if the only blinking text was temporarily
    scrolled out of view, e.g., using the scrollbar.
    • 

    
  • fix an (old) flaw in the delete-line operation where the
    text which is scrolled into view while the display is scrolled
    up was not repainted.
    • 

    
  • improve delete-line and insert-line operations, retaining
    selection when the selection does not intersect the
    deleted/inserted lines.
    • 

    
  • fix an (old) off-by-one error when an application cleared
    above the cursor position while the display was scrolled up,
    that would leave an extra line of text uncleared.
    • 

    
  • fix a similar problem where the double-size attribute would
    not be reset when clearing the screen while the display was
    scrolled up.
    • 

    
  • fix an indexing error which would occur if an application
    cleared a line while the display was scrolled up and was also
    in UTF-8 mode (Redhat #524503). The error was from patch #228 but more visible after changes from
    patch #244.
    • 
  


  
Patch #248 -
  2009/9/11


  
    
    
  • fix an overlooked adjustment for selecting double-width
    characters in the narrow-character configuration.
    • 

    
  • eliminate uses of XTERM_CELL and
    XTERM_CELLC where an appropriate
    LineData pointer is available.
    • 

    
  • correct expression in okScrnRow macro, making
    selections give the length of lines below the visible screen
    (report by Stuart Henderson).
    • 

    
  • correct logic used to improve performance of missing-glyph
    check, which did not handle line-drawing characters (Debian
    #545220).
    • 
  


  
Patch #247 -
  2009/8/30


  
    
    
  • add ifdef's and check for openpty() on DragonFly (patch by
    Alex Hornung).
    • 

    
  • correct calculation for size of line's data block, which
    was sometimes off-by-one when configured using
    --enable-16bit-chars (report by H Merijn
    Brand).
    • 

    
  • fix indexing error in print-everything feature from
    patch #246 (patch by Ovidiu
    Gheorghioiu).
    • 
  


  
Patch #246 -
  2009/8/16


  
    
    
  • remove obsolete logic for saving/restoring wrapping flags,
    which did not work on 64-bit platform. Wrapping flags (stored
    in the line-index) are now copied with line-data (Debian
    #541160).
    • 

    
  • modify comments in app-defaults files to avoid problem with
    C preprocessor used by xrdb (Debian #541603).
    • 

    
  • restore special case in makeColorPair, needed
    for colorBDMode resource (Debian #541089).
    • 

    
  • correct SetLineFlags() macro, broken in
    patch #244 when recoding to avoid
    gcc-specific bitfields (Debian #541236).
    • 

    
  • modify initialization of screen buffers to ensure that
    pointers align to int-boundaries. This fixes a problem
    introduced in patch #244 where the
    color- and character-arrays (stored after the video-attributes
    in each row) might be misaligned (report by Rajeev V
    Pillai).
    • 

    
  • add limit-check in ScrnRefresh for handling
    saved-lines from the circular buffer which are repainted on a
    screen whose width has increased. To improve performance,
    circular buffer entries are not resized (report by Rajeev V
    Pillai).
    • 

    
  • correct type for CellColor (a late change in
    patch #244 to avoid gcc-specifc enums
    made that unsigned rather than unsigned short, for the
    256-color option).
    • 

    
  • fix typo in configure option --enable-16bit-chars (report
    by Rajeev V. Pillai).
    • 
  


  
Patch #245 -
  2009/8/12


  
    
    
  • correct a special case in saving FIFO-lines from patch #244. If the screen was shrunk, xterm
    used the wrong amount for copying to FIFO-lines, and then used
    this amount to adjust the current row on the screen. That was
    both a visible defect (Debian #541109) as well as a potential
    addressing error (Debian #541132, Debian #541160, and Debian
    #541236).
    • 

    
  • add clarification in xterm manual about the various
    allowXXXOps resources, which are disabled
    when the allowSendEvents resource is active (patch
    by Julien Cristau, Debian #531597).
    • 
  


  
Patch #244 -
  2009/8/9


  
    
    
  • refactored storage of saved-lines, providing a configure
    option to manage them as a FIFO (actually a circular buffer),
    improving performance. Added configure option
    --enable-fifo-lines to enable/disable the new
    feature (it is enabled by default).
    • 

    
  • added fastScroll resource, to amuse people who
    measure terminal emulator performance by cat'ing
    large files to the screen.
    • 

    
  • modify check in readPtyData from return values
    to provide exit on zero-bytes read from pty for FreeBSD, or
    eliminate high-CPU in "xterm-hold" processing (discussion with
    Ulrich Spoerlein, FreeBSD ports/136686). The check was
    originally modified to combine negative/zero values in
    XFree86-3.1.2E, 1996/05/06.
    • 

    
  • add configure option --enable-16bit-chars to
    provide wide-characters with 16-bits (rather than the default
    32-bits).
    • 

    
  • add retryInputMethod resource to allow
    configuring out the retries xterm uses to connect to
    non-responsive XIM server, to work around defective X
    configurations as noted in 
    NetBSD mailing list.
    • 

    
  • make regular-expression selection work for VT100
    double-sized characters.
    • 

    
  • improve layout when drawing missing characters in a
    proportional font, e.g., as boxes, to take into account whether
    they are double-width (report by Guilbert Stabilo on
    comp.unix.shell).
    • 

    
  • add capability for keypad-center (kb2/KA2) to termcap entry
    for xterm-new, as well as xterm-8bit, xterm-sun and xterm-vt220
    (FreeBSD conf/136336).
    • 

    
  • change default for keepSelection resource to
    true (prompted by discussion with David Muir Sharnoff).
    • 

    
  • remove a limit-check in ptydata.c, allowing Unicode values
    past 64k to be displayed using TrueType fonts (Debian
    #458432).
    • 

    
  • remove a vt52-specific ifdef to allow mapping F1-F4 to
    PF1-PF4 when vt52 support is not compiled (report by Olaf
    'Rhialto' Seibert).
    • 

    
  • save/restore line-wrapping flags when converting from
    ISO-8859-1 encoding to UTF-8 encoding, as well as when resizing
    screen.
    • 

    
  • remove extra adjustment of position in fix for Debian
    #418324.
    • 

    
  • modify default check for mkWidth resource to
    check for line-drawing characters, which are categorized as
    double-width in Solaris 10 (report by Sebastian Kayser).
    • 

    
  • add "print-everything" action (patch by Ovidiu
    Gheorghioiu).
    • 

    
  • start refactoring scrollback data using new getLineData()
    function.
    • 

    
  • demote recent change to Debian #252873 fix to experimental,
    ifdef'd out as EXP_BOGUS_FG (Debian #522141).
    • 

    
  • work around groff mapping of ASCII quotes using macros
    (requested by Reuben Thomas based on Colin Watson advice, fixes
    Debian #378700).
    • 

    
  • correct symbol used for default of
    allowWindowOps which was
    DEF_ALLOW_FONT rather than
    DEF_ALLOW_WINDOW (report by Matthieu Herrb).
    • 

    
  • amend fix for tek4014 from patch
    #243 to make it only apply to the Tek Options menu.
    • 
  


  
Patch #243 -
  2009/3/28


  
    
    
  • revert change to default for allowTcapOps
    (request by Bram Moolenaar).
    • 

    
  • reallocate result returned by xtermEnvLocale()
    to avoid reference to freed memory after handling
    menuLocale resource.
    • 

    
  • fix an old (X11R5) bug in tek4014 for switching
    fontsizes.
    • 

    
  • add resource defaultString to make
    configurable the use of "#" when pastes of UTF-8 text fail due
    to limitations in the current locale settings.
    • 

    
  • make the set of selection target Atom's configurable by two
    new resources eightBitSelectTypes and
    utf8SelectTypes, e.g., to use the
    TEXT Atom in preference to
    UTF8_STRING (discussion with Stanislav Sedov
    regarding koi8rxterm and the FreeBSD port).
    • 

    
  • modify handling of TARGETS Atom by making it
    return exactly the set of targets as those which xterm is
    currently providing.
    • 

    
  • set MANPAGER and PAGER explicitly
    to /bin/cat in minstall.sh to work around
    /etc/man.conf's with those variables already set (report by
    Марьясин
    Семён).
    • 

    
  • improve error-checking of tcap-query parser.
    • 

    
  • add check for keyboard tcap), which ensures
    that terminal descriptions containing the same string for
    shifted/unshifted keys will be seen by tcap-query as only the
    unshifted key. (This would only happen with an incorrect
    terminal description).
    • 

    
  • fix conversion for input event-state to modifier-parameter
    which made tcap-query feature not work with
    tcapFunctionKeys (keyboard type
    tcap).
    • 

    
  • add "DEF_ALLOW_XXX" definitions to main.h to allow
    overriding the default compiled-in values for
    "allowxxx" resources.
    • 

    
  • remove check on bell-percentage added in patch #242, which disallowed zero/negative
    values (Redhat Bugzilla #487829).
    • 
  


  
Patch #242 -
  2009/2/15


  
    
    
  • fix configure check for XkbBell and provide
    appropriate parameter for it.
    • 

    
  • fix a caching problem with double-size fonts versus reverse
    video that could cause core dump.
    • 

    
  • repair double-size fonts from workaround used in patch #240.
    • 

    
  • add new section to the VT Fonts menu which allows enabling
    or disabling the font, termcap (tcap-query), title and window
    operations.
    • 

    
  • add fontWarnings resource, to control whether
    to show warnings on failure to load a font.
    • 

    
  • improve warnings for unloadable fonts introduced in
    patch #240 by limiting those to the
    cases where a font would be specified directly by a resource
    setting rather than a derived fontname.
    • 

    
  • further amend fix for Debian #252873 from patch #197 to treat a blank cell which does
    not have both foreground and background colored as a
    non-colored cell. This improves a special case where the cursor
    is on a blank cell which had foreground color scrolled in
    (report by Miroslav Lichvar).

      
    Also add the same logic when hiding cursor, so the outline
      matches the in-focus cursor.
    
    
    • 

    
  • modify internals to reduce places PAIRED_CHARS() is used,
    making WriteText() and ScrnWriteText() accept IChar array, as
    well as providing a wrapper for drawXtermText().
    • 

    
  • change default XIM font from "*" to "fixed" to improve
    startup time in zh_CN.UTF-8 locale (Mike Fabian, SuSE Bugzilla
    #464930).
    • 

    
  • typo in #240 log (Slava Semushin)
    • 
  


  
Patch #241 -
  2009/1/26


  
    
    
  • improve checks for missing bitmap fonts, fallback to
    "fixed" as needed to work around broken font-packages (report
    by Jacek Luczak).
    • 

    
  • fix breakage from patch #240
    changes for xtermAddInput() (patches by Jeff Chua,
    Julien Cristau).
    • 
  


  
Patch #240 -
  2009/1/25


  
    
    
  • use plink.sh for linking xterm (suggested by
    Larry Doolittle).
    • 

    
  • add resource descriptions for input method to xterm
    manpage.
    • 

    
  • update configure script; consistently append to $CFLAGS
    rather than prepend.
    • 

    
  • add install-scripts rule to makefile, to allow
    koi8rxterm and uxterm scripts to be altered independently of
    install-bin
    • 

    
  • add -maximized command-line option and
    corresponding resource (prompted by alt.os.linux newsgroup
    comment).
    • 

    
  • modify translations of scrollbar widget using
    xtermAddInput() (see patch
    #181) to accept the actions that the vt100 widget accepts,
    such as shift-insert to perform a paste operation (request by
    Martin Zwickel).
    • 

    
  • change default for allowTcapsOps resource to
    false, since it causes unexpected behavior for vim users with
    AltGr.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #239 -
  2009/1/8


  
    
    
  • correct a cast in input.c, which broke translation of
    numeric keypad codes to pageup, pagedown, etc., on 64-bit
    platform (Debian #511138, report by Larry Doolittle).
    • 
  


  
Patch #238 -
  2008/12/30


  
    
    
  • update configure macro CF_XOPEN_SOURCE for AIX 6.x and Mint
    platforms.
    • 

    
  • reset the screen wrapping-flag at the end of
    ClearRight to fix an occasional case where the
    last character of a scrolled and wrapped line would be cleared
    (patch by Joe Peterson).
    • 

    
  • modify to use POSIX coding for comparing resource settings
    such as locale, to work with locales such as
    Turkish (report by M Vefa Bicakci).
    • 

    
  • turn on configure paste64 feature by default
    (request by Jean-Philippe Bernardy). It is runtime
    enabled/disabled with allowWindowOps.
    • 

    
  • turn on configure tcap-query feature by
    default, add resource allowTcapOps to make this
    runtime enabled/disabled.
    • 

    
  • make OSC 3 (change X property, from patch #110) subject to
    allowWindowOps resource.
    • 

    
  • make VT220 DSR responses inactive in
    VT100-mode.
    • 

    
  • make DECUDK feature inactive in
    VT100-mode.
    • 

    
  • respond to incorrectly formatted DECRQSS with
    a cancel.
    • 

    
  • add allowFontOps resource to allow the
    fontsize-switching and font query/set control sequences to be
    enabled/disabled (prompted by Debian #510030).
    • 

    
  • some code cleanup based on gcc 4.x
    -Wconversion warnings in button.c and
    charproc.c
    • 

    
  • modify tcap-query feature to not return data
    for shifted cursor-keys when the keyboard type is set to vt220,
    since returning the same string for shifted/unshifted keys may
    confuse some applications (Gentoo #212546).
    • 
  


  
Patch #237 -
  2008/09/14


  
    
    
  • improve usability of TrueType fonts by making the font-size
    switching for shifted keypad plus/minus use the
    faceSize resources to determine the order of fonts
    (when TrueType fonts are used) rather than the bitmap fonts,
    since their sizes may not be in the same order (report by H
    Merijn Brand)
    • 

    
  • remove an optimization of ConfigureNotify
    events from patch #236 which seems to
    interfere with passing SIGWINCH to applications
    (Gentoo #233836).
    • 

    
  • modify handling of altSendsEscape to reset the
    eightBitInput mode, like
    metaSendsEscape (patch by Ted Phelps).
    • 

    
  • add feature to show the text-cursor as an underline rather
    than a box, plus command-line options -uc and
    +uc and resource cursorUnderLine to
    control the feature (patch by Paul Lampert).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #236 -
  2008/07/27


  
    
    
  • correct memory reallocation when handling a paste of UTF-8
    text from patch #225 changes
    (report/patch by Max Mikhanosha).
    • 

    
  • correct allocation of temporary buffer in
    xtermFindShell in case the user's
    $PATH contains no ":" (report/analysis by Victor
    Stinner, Freedesktop.Org Bugzilla #16790).
    • 

    
  • modify CF_XOPEN_SOURCE to add case for DragonFly BSD, to
    fix new compile problem exposed by fix for fd_mask (patch by
    Hasso Tepper).
    • 

    
  • add configure-check for ncurses
    use_extended_names, (report by Martin
    Mokrejs).
    • 

    
  • correct computation for toolbar height; layout manager
    already takes into account borderWidth
    resource.
    • 

    
  • implement VT320-style SCS (select character set) for ISO
    Latin-1 supplemental.
    • 

    
  • fixes for vt100-style character sets in UTF-8 mode (Ubuntu
    #230919).
    • 

    
  • fix to make luit work with xterm's
    -ls option (report/patch by Marius Tolzmann).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #235 -
  2008/04/20


  
    
    
  • add control sequences for some of the recent resource/menu
    settings:

      
      
        
    • altSendsEscape (private mode 1039)
      • 

        
    • keepSelection (private mode 1040)
      • 

        
    • selectToClipboard (private mode 1041)
      • 

        
    • bellIsUrgent (private mode 1042)
      • 

        
    • popOnBell (private mode 1043)
      • 
      
    
    
    • 

    
  • add resource formatOtherKeys to provide an
    alternate escape sequence format for the
    modifyOtherKeys resource (request by Paul LeoNerd
    Evans).
    • 

    
  • adjust saved-cursor position if the window is resized while
    displaying the alternate screen (Novell #196880, Debian
    #383384).
    • 

    
  • improve pointer-checks to fix a bug exposed by resizing
    during initialization under StumpWM window manager (Fedora
    Bugzilla #437928).
    • 

    
  • modify unselectwindow() to ensure that the
    mouse pointer is not hidden after xterm loses focus (report by
    Jeremy Huddleston).
    • 

    
  • add special check for fd_mask on Mac OS X (report by Jeremy
    Huddleston).
    • 

    
  • add dylib to autoconf's suffix list used for
    checking the result from xmkmf, to work with Mac
    OS X (report by Jeremy Huddleston).
    • 

    
  • correct initialization of bold- and wide-, wide-bold fonts
    which may be set via the utf8Fonts subresource
    (Debian #347790).

  • modify sinstall.sh to use POSIX locale to
    bypass GNU ls changes to date-format.
    • 

    
  • improved/refined changes for closing bitmap font (patch by
    Andrea Odetti).
    • 

    
  • improve resize computation for situations where the
    negotiation fails, by invoking the xterm widget's core-class
    resize method (Debian #365602, patch by Jim Paris).

  2008/02/24


  
    
    
  • add configure check for ttydefaults.h, include
    if needed, e.g., for systems where defining
    _POSIX_C_SOURCE, etc., prevents it from being
    included via termios.h (prompted by comments by
    Robert Delius Royar and Jeremy Huddleston).

  • correct macro name used for default CKILL
    definition to work with Mac OS X (report by Jeremy
    Huddleston).
    • 
  


  
Patch #232 -
  2008/01/30


  
    
    
  • corrected logic in a font-cache used for reverse-video
    (Debian #404079).
    • 

    
  • add control sequence to alter pointerMode at
    runtime.
    • 

    
  • add limit-checks for rectangle operation parameters (report
    by Martin Pirker).
    • 

    
  • modify minstall.sh to suppress
    $MANPAGER and $PAGER environment
    variables, which may interfere with redirecting output of
    man to a shell variable (report/patch by Zdenek
    Sekera).
    • 

    
  • do not try to hide mouse pointer in the tek4014 window,
    fixes broken "-t" option at startup from patch #230 changes (report by Robert K.
    Nelson).
    • 

    
  • correct datatype used when drawing tek4014 data using xterm
    compiled for wide-characters, on big-endian machines (reports
    by Jeremy Huddleston, Harald Hanche-Olsen, Martin Costabel,
    Merle Reinhart).
    • 

    
  • modify to cache the font-names along with the bitmap font
    data, to improve comparison of fonts.
    • 

    
  • modify to allow building with configure options
    --disable-ansi-color and
    --disable-leaks (Debian #459817, report/patch by
    Németh Márton).
    • 

    
  • modify to allow building with configure options
    --enable-wide-chars and
    --disable-c1-print (Debian #459816, report/patch
    by Németh Márton).
    • 

    
  • add pointerMode resource to control whether
    and when the pointer cursor is hidden as the user types.
    • 

    
  • simplify initialization of ttyMode- and related characters
    using a table.
    • 

    
  • modify initialization-logic for stty values that correspond
    to ltchars structure and the BSD TIOCSLTC ioctl (susp, dsusp,
    rprnt flush, werase, lnext). These were reset to constants for
    both termios and legacy interfaces immediately after asking the
    system for the existing values since X11R6.1, rather than using
    them to provide inherited values. While the legacy interface
    has some constraints, e.g., on HPUX, the POSIX or termios
    interface should not. Your shell may reset these anyway
    (prompted by patch by Ed Schouten).
    • 

    
  • improve logic for hiding/displaying pointer-cursor (report
    by Mark Brukhartz).
    • 

    
  • add limit-checks to tabs.c, increase maximum column for
    setting tab-stops from 320 to 1024 (report by Németh
    Márton).
    • 

    
  • correct length, i.e., number of types of selection targets,
    computed by ConvertSelection() when not handling
    wide characters for the XA_TARGETS() case. This
    leaves an extra Atom on the end of the list which is not
    handled by Java
    applications. The problem was introduced in patch #151 (report by David Wood).

Patch #231 -
  2008/01/05


  
    
    
  • undo change to getXtermCell() from patch #230
    using PACK_PAIR macro (Debian #459014, analysis by
    Caetano Jimenez Carezzato).
    • 

    
  • minor documentation fixes (patch by Slava Semushin)
    • 

    
  • add makefile actions to install KOI8RXTerm app-defaults
    file (patch by Julien Cristau).
    • 
  


  
Patch #230 -
  2007/12/31

    suppresses cursor repainting when NotifyGrab and
    NotifyUngrab event types are received during
    change of focus (request by Nicolas George).
    • 

    
  • do not treat Unicode BIDI control characters as combining
    characters (Debian #457634).

    since it confuses some lookups following the 
    Icon Theme Specification (report by Slava Semushin)
    • 

    
  • correct width-calculation used for adjusting proportional
    fonts, to work with wide-characters (Debian #441354).
    • 

    
  • fixes/improvements for double-size characters:

      
      
        
    • correct old clipping calculation which used total
        height of glyphs where ascent was needed.
      • 

        
    • if bold font is unavailable, fall back to normal
        font
      • 

        
    • adjust to "work" with Xft (which does not support
        double-width single-height characters).
      • 

        
    • restore reset of doublesize for a line when it is
        cleared, broken in patch
        #228.
      • 
      
    
    
    • 

    
  • modify logic for forceBoxChars resource when
    using TrueType fonts to be consistent with bitmap fonts
    •

    characters which are available in the font.
    • 

    
  • modify rectangle-support functions to preserve colors when
    filling/erasing to match WRQ Reflection behavior (request by
    Enzo Toscano).
    • 

    
  • add getopt-parsing to tcapquery.pl, including feature to
    test the extended cursor/editing keys.
    • 

    
  • make missing double-width glyphs display as double-width
    (Debian #456236).
    • 

    
  • change tcap-fkeys and rectangles
    configure options to enable them by default.
    • 

    
  • hide the mouse pointer while user is typing (request by
    Rodolfo Borges).
    • 

    
  • extend configure options --enable-tcap-query
    and --enable-tcap-fkeys to send cursor- and
    editing-keypad keys modified according to the keyboard (or
    termcap) selection for shift, alt, control, meta.
    • 

    
  • modify kdch1 in termcap, e.g.,
    xterm-r6 to match the terminfo file.
    • 

    
  • add -hm option to turn
    highlightColorMode on or off.
    • 

    
  • add highlightColorMode resource to separate
    the new (since patch #225)

    report/example by Thomas Wolff).
    • 

    
  • add Keep Selection menu entry to turn the
    keepSelection resource on/off at runtime.
    • 

    
  • add keepSelection resource, which when
    enabled, tells xterm to retain the X selection even after it
    stops highlighting it (patch by Sergey Vlasov).

  • extend the CSI > n sequence to
    allow disabling all types of modified-keys that the
    CSI > m sequence affects.
    •

  • extend terminfo building blocks for modified editing keys
    to include all six keys.
    • 

    
  • synchronize terminfo with ncurses (report by Stephane
    Chazelas)

      
      
        
    • equate xterm-xfree86 and
        xterm-xf86-v44.
      • 

        
    • add ncurses extensions OTbs, AX, for termcap
        conversions.
      • 

        
    • make old/legacy entries such as xterm-24,
        xterm-65 and aliases xterms,
        vs100 inherit from
        xterm-old.
      • 

        
    • make xterm-r5 and xterm-r6

    • 

    
  • modify "Quit" menu entry to override the -hold
    command-line option.
    • 

    
  • add a check in the startup error-reporting to avoid writing
    to pipe when it has not been opened. In that case, report
    errors directly to the standard error.
    • 

    
  • add OPT_READLINE definition to xtermcfg.hin, overlooked in
    patch #205 (report by Kalle Olavi
    Niemitalo).

  • modify 88colors2.pl and
    256colors2.pl, adding -r option to
    reverse the palettes for the extended colors.
    •

    initialization (Debian #403360).
    • 

    
  • correct index expression used to set line-wrapping flag,
    making selection from scrollback work consistently (Debian
    #430121, report by Vincent Lefevre).
    • 

    
  • amend changes to handshake in patch
    #226 to accommodate Solaris, which relies on the extra
    setting of the terminal size after I/O initialization. Do this
    by adding new resource ptySttySize, which is false
    for Linux and MacOS X, i.e., true for for Solaris and other
    SVR4 platforms, as well as FreeBSD (reports by David Wood,
    Renato Botelho).
    • 

    
  • check for X events after cursor-left, and carriage return,
    consistent with indexing operations (comments by Vegard Nossum
    and Ingo Molnar on a mailing-list).
    • 

    
  • initialize the .keyboard structure, needed for
    some platforms (such as Solaris) after patch #227 fixes for keysyms (patch by David

    options added in patch #226.
    • 

    
  • modify change for Debian #422521 from patch #226 to work with configurations where
    the X server does not recognize the XF86Paste or
    SunPaste keysyms (report by Paolo Pumilia).
    • 

    
  • fix incorrect free in fix for "Selection" menu entry in
    patch #226.
    • 
  


  
Patch #226 -
  2007/6/17


  
    
    
  • add configure check to use
    -Wno-unknown-pragmas for Solaris, and a few other
    new gcc warning options to address regressions in its warning
    options.
    • 

    
  • add sample desktop and icon files, along with configure
    options for manipulating them.
    • 

    
  • fix an infinite loop when showing a 2-column character in a
    1-column screen (Debian #426863).
    • 

    
  • add XF86Paste and SunPaste to the
    default translations (Debian #422521, patch by Bernhard R
    Link).
    • 

    
  • update wcwidth.c (partly based on/prompted by mailing list
    comment).
    • 

    
  • update/improve keysym2ucs.c based on Unicode 5.0.1d3 and
    Xorg 7.1 keysymdef.h file.
    • 

    
  • improve gen-pc-fkeys.pl, making it show all of
    the building-block terminfo entries used by xterm.
    • 

    
  • correct strings used for modifiers applied to F1-F4 in
    xterm+pcf1 terminfo entry.
    • 

    
  • improve session management by adding the ICE connection
    number to the select call rather than waking up
    once per second (patch by Miroslav Lichvar).
    • 

    
  • add environment variable $XTERM_LOCALE to help
    with shell initialization, e.g., to set a specific locale for
    xterm on systems where a global locale is set in the shell
    startup scripts.
    • 

    
  • add resource settings mkSampleSize and
    mkSamplePass to modify the mkWidth
    added in patch #201. In patch #202, xterm would also check if the
    system's wcwidth matched its built-in tables "well
    enough" to be used when mkWidth was false, and if
    not would use the built-in tables anyway. These resources allow
    the user to customize the decision (prompted by comments by
    Emanuele Giaquinta)
    • 

    
  • modify logic which resets/updates the screensize on the
    child process side of the pseudo-terminal to do this only if a
    successful handshake was received, e.g., as determined by the
    waitForMap resource (prompted by reports by
    Emanuele Giaquinta and Bernhard R Link, but see also patch #177 and patch
    #159.
    • 

    
  • improve permissions logic when closing pseudo-terminal
    (Debian #12261, patch by Nathanael Nerode, analysis by Richard
    Braakman).
    • 

    
  • add resource highlightReverse which controls
    whether xterm will allow selection highlighting to hide
    reverse-video or use the older behavior which inverts the
    foreground and background colors when selected text with
    reverse-video attribute (report by Adam M Costello, comments by
    Victor Vaile).
    • 

    
  • restore a special case for cursor-color in
    ReverseVideo() lost in rewrite for patch #224 (report by Adam Sulmicki).
    • 

    
  • correct initialization for menu entry for
    bellIsUrgent (patch by Emanuele Giaquinta).
    • 

    
  • correct length of underlining for double-width Xft fonts
    (report by Shidai Liu "Leo").
    • 

    
  • correct clipping for double-width Xft fonts (report by
    Shidai Liu "Leo").
    • 

    
  • modify initialization for italicULMode to
    avoid XftPatternBuild reusing bold attributes
    (report by Shidai Liu "Leo").
    • 

    
  • add a check in case someone tries to call the
    popup-menu() action on a menu which is not
    initialized (Debian #426364).
    • 

    
  • improve CF_IMAKE_CFLAGS to work with Solaris sed (report by
    Peter Bray).
    • 

    
  • improve guess for X's manpage section in
    minstall.sh, (prompted by comment by Miroslav
    Lichvar).
    • 

    
  • modify minstall.sh to handle manpage patch
    with more than one dot (patch by Miroslav Lichvar).
    • 

    
  • fix configure message for --disable-setgid option (patch by
    Miroslav Lichvar).
    • 

    
  • add allowTitleOps resource to allow users to
    prevent the title- and icon-names from changing (request by
    John Bashinski).
    • 

    
  • fix "spawn-new-terminal" action, for the case where no
    parameter is passed to the action (patch by Daniel
    Colascione).
    • 

    
  • fix error-checking on internal font switching for
    "Selection" menu entry (Debian #421523).
    • 

    
  • amend select/paste change from patch
    #225 by limiting it to non-UTF-8/non-KOI8-R encoding
    (Debian #420974).
    • 

    
  • add workaround for groff ".URL" codes which are not present
    in some commonly-used bitmap fonts (Debian #418324).
    • 
  


  
Patch #225 -
  2007/3/24


  
    
    
  • add useClipping resource to allow clipping to
    be disabled.
    • 

    
  • use XftDrawSetClipRectangles to work around
    Xft pixel-trash (report by Reuben Thomas).
    • 

    
  • add configure option --enable-tcap-fkeys, and
    resource tcapFunctionKeys, which can be used to
    tell xterm to use function-key definitions from the termcap (or
    terminfo) which it uses to set $TERM on startup.
    • 

    
  • add resources altIsNotMeta and
    altSendsEscape to allow one to use Alt-keys like
    the meta-key even if they are bound to different keycodes
    (prompted by discussion with Daniel Jacobowitz).
    • 

    
  • revert a change from patch #216
    that unnecessarily made the meta modifier override the
    eightBitInput resource if the alt- and
    meta-modifiers happened to overlap (report/patch by Daniel
    Jacobowitz).
    • 

    
  • correct associated font for active icon for colored text
    (broken in patch #224).
    • 

    
  • correct ifdef's for Darwin (patch by Emanuele
    Giaquinta).
    • 

    
  • add highlightTextColor resource, and options
    -selfg, -selbg like xwsh
    (adapted from patch by Victor Vaile).
    • 

    
  • revise find_closest_color() function to
    address concern about borrowing from Tcl/Tk
    (request by Dan McNichol).
    • 

    
  • add "spawn-new-terminal" action, which can be assigned to
    key translation, allowing one to spawn a new copy of xterm
    using the current process' working directory (adapted from
    patch by Daniel Colascione).
    • 

    
  • improve select/paste between UTF-8 and Latin1 xterms by
    adapting the translations from patch
    #185. Extend that to include Unicode fullwidth forms
    FF00-FF5E. Also modify select/paste of DEC line-drawing
    characters in Latin1 mode to use ASCII characters.
    •

    • 

    
  • add --disable-setgid configure option (request
    by Miroslav Lichvar).
    • 

    
  • fix a possible infinite loop in last change to
    dabbrev-expand() (patch by Emanuele
    Giaquinta).
    • 

    
  • modify initialization to set the pty erase value if the
    erase is set in the ttyModes
    resource. This overrides the ptyInitialErase
    setting (request by Lluís Batlle i Rossell).
    • 

    
  • add initialFont resource to xterm widget, like
    tek-widget (Debian #299669).
    • 

    
  • amend change to boldMode from patch #223 for Debian #347790. As noted in
    Debian #412599, that made xterm no longer match the documented
    behavior. Add new resource alwaysBoldMode to allow
    overriding the comparison between normal/bold fonts when
    deciding whether to use overstriking to simulate bold
    fonts.
    • 

    
  • restore background color in ClearCurBackground(), omitted
    in changes for patch #223 (report by
    Miroslav Lichvar).

    characters (prompted by test-case for Novell #246573).
    • 

    
  • add a check to avoid trying to repeat a multibyte character
    (report by Sami Farin).
    • 

    
  • modify parameter to XftNameParse() to select
    wide face-name as needed, to make -fd option work
    (patch by Mike Fabian, Novell #246573).
    • 

    
  • correct logic for mouse highlight tracking's abort
    sequence, broken in a restructuring modification from patch #224 (report by Thomas Wolff).
    • 

    
  • revert the simplification of blinking cursor, since that
    broke the xor'ing introduced in patch
    #193 (report by Thomas Wolff).
    • 
  


  
Patch #224 -
  2007/2/11


  
    
    
  • simplify code for set/reset mode for blinking cursor (patch
    by Emanuele Giaquinta).
    • 

    
  • modify dabbrev-expand() to restart after the
    last match (patch by Emanuele Giaquinta).
    • 

    
  • add control sequences for enabling/disabling focus in/out
    event reporting (request by Bram Moolenaar).
    • 

    
  • improve startup performance of menus by adding resource
    setting menuLocale which can be set to override
    X's lengthy initialization of fontsets - which are seldom used
    for the Xaw popup menus (adapted from patch by
    Dave Coffin).
    • 

    
  • modify do_precomposition() function and make-compose.sh to
    handle 21-bit codes vs the 16-bit codes those were written for,
    and fix a few mis-sorted codes (patch by Thomas Wolff).
    • 

    
  • handle special case in -cjk_width which
    unexpectedly caused a character's width to change when a
    combining character (patch by Thomas Wolff)
    • 

    
  • fix build for GNU/KFreeBSD (Debian #40111).
    • 

    
  • consolidate GC creation/updating into a single module to
    reduce GC manipulation (prompted by Debian #389476, though a
    complete fix would involve optimizing the scrolling
    behavior).
    • 

    
  • fix ifdef of xtermCellWidth(), which broke for a case
    without TrueType and without wide-character support (report by
    Martin Pirker).
    • 

    
  • undo a comparison in
    handle_translated_exposure which did not work due
    to X server optimization. That caused the inner border to be
    repainted with unexpected colors when handling a repaint, e.g.,
    after switching to/from another workspace (Debian #401726,
    Redhat Bugzilla #223027).
    • 

    
  • allow -cr option to override cursor color when
    -ah option is used (Debian #406502).
    • 

    
  • add a note in xterm's manpage explaining that the
    -bw (or -w) option is only used by
    the window manager, if at all (Debian #405043).
    • 

    
  • make Selection of VT Fonts
    work with selectToClipboard resource.
    • 

    
  • correct length calculation for Selection entry
    of VT Fonts menu, broken since it ignored the
    actual selection length since X11R4.
    • 

    
  • fixes for fontsize changes with -fa option
    (Redhat Bugzilla #222340).
    • 
  


  
Patch #223 -

  • add --enable-rectangles configure option
    (request by Martin Pirker).
    • 

    
  • correct default value for --with-symlink
    configure option.
    • 

    
  • fixes configure script macros that use
    $X_EXTRA_LIBS.
    • 

    
  • modify configure script to provide support for pre-package
    config versions of Xft aka "FreeType".
    • 

    
  • add the Xaw scrollbar translations resource to the xterm
    manpage, add an example showing how to change the mouse button
    assignments (Debian #382225).
    • 

    
  • amend a change from patch #216,
    which omitted modifiers for control, meta, etc., if they were
    mixed with any other modifiers. The intent of the change was to
    avoid confusion with XK_Mode_switch and
    XK_ISO_Level3_Shift; the check is now done
    explicitly (report by Daniel Jacobowitz).
    • 

    
  • interpret a negative value for
    modifyCursorKeys or
    modifyFunctionKeys resources to disable the
    respective features (prompted by Novell #220728).
    • 

    
  • amend cell-width computation for FreeType from patch #217, which did not work for VT100
    line-drawing characters (Debian #399638, Gentoo #147111).
    • 

    
  • amend a change from patch #216,
    which made alt-modifier on a cursor-key send a modifier
    parameter (Novell #220728).
    • 

    
  • correct an off-by-one that made DECCRA not work
    (report/patch by Martin Pirker).
    • 

    
  • revert an optimization in SGR_Foreground() and
    SGR_Background from patch #209 (Debian
    #347722, analysis by Pierre Lombard).
    • 

    
  • fix for boldMode (Debian #347790, patch by Tim
    Pope).
    • 

    
  • amend fix for -iconic in patch #208, which broke the positioning part
    of -geom with toolbar configuration.
    • 

    
  • fix to prevent indexing error in regular expressions (patch
    by Dennis Schneider).
    • 

    
  • fixes to make the internalBorder area not change color due
    to reverseVideo and/or related exposure events. The latter was
    a very old bug exposed in patch #196
    (report by Neil Hoggarth, also Debian #397624).
    • 
  


  
Patch #222 -
  2006/10/17


  
    
    
  • minor optimization for recoloring cursor via dynamic
    colors.
    • 

    
  • fix a bug caused by restructuring of tek4014 widget (report
    by Paul Schenkeveld)
    • 
  


  
Patch #221 -
  2006/10/1


  
    
    
  • fix for regular expressions: the code which converted the
    column offset within a line did not check properly for the end
    of a line, and if allowed to match the whole line, would select
    the beginning of the following line. If the following line were
    empty, in turn it would select from the next, etc. (report by
    Sean Reifschneider).
    • 

    
  • minor optimization of color allocation to avoid repainting
    the screen if the corresponding color had not been
    allocated.
    • 

    
  • fixes for vttests/256colors.pl (report by Egmont
    Koblinger).
    • 

    
  • add terminfo building block entries for modifiers of the
    6-key editing keypad.
    • 

    
  • fix for initialization of tek4014 which broke on QNX
    6.1
    • 
  


  
Patch #220 -
  2006/9/10


  
    
    
  • make "xterm -t -iconic" work as expected, i.e., start in
    tek4014 mode, but iconified.
    • 
  


  
Patch #219 -
  2006/9/4


  
    
    
  • some internal restructuring to separate data for vt100 and
    tek4014 widgets.
    • 

    
  • fix a few cases where form-events would be seen by the
    vt100 widget when built with the toolbar configuration.
    • 
  


  
Patch #218 -
  2006/8/27


  
    
    
  • change behavior when encountering an illegal character in a
    title string. Rather than reject the string, translate illegal
    characters into "?" and use the string (requested by Thomas
    Wolff).
    • 

    
  • improve checks for nonprinting characters in title strings
    (report by Samuel Thibault).
    • 

    
  • correct typo in menu labels, changing
    print-redirect to print-redir, making
    it follow the manpage and match the usage for the actions table
    (report by Samuel Thibault).
    • 

    
  • correct a typo that prevents building with some older
    systems such as Solaris 2.6 (report by Julian Bridle).
    • 
  


  
Patch #217 -
  2006/8/20


  
    
    
  • minor improvements to FreeType font layout and
    drawing.
    • 

    
  • add a check in the ptyInitialErase logic to ensure that the
    termcap was read (Redhat Bugzilla #201246).
    • 

    
  • limit changes for reverse-video from patch #216 to cases where the reverse-video
    command-line option is used (report by Zdenek Sekera).
    • 

    
  • correct bitmap-derived pointsizes for TrueType fonts; they
    should be proportional to the square root of the area of the
    bitmap fonts.
    • 

    
  • add resources to specify pointsize of TrueType fonts
    (request by Reuben Thomas).
    • 

    
  • improve install of terminfo by filtering out harmless
    messages related to extended capabilities. At the same time,
    use ncurses tic to compile the extended capabilities if
    possible (report by Zdenek Sekera).
    • 

    
  • update "xterm+pcfkeys" terminfo entry to correspond to
    patch #216.
    • 
  


  
Patch #216 -
  2006/8/3


  
    
    
  • improve handling of ConfigureNotify events by
    checking if there are further events in the queue which
    obsolete the current one (adapted from rxvt 2.7.5). Only the
    normal normal (non-toolbar) configuration is addressed in this
    patch.
    • 

    
  • several changes to terminfo:

      
      
        
    • incorporate some minor changes from ncurses to help
        keep these synchronized:

          
      
            
      2005-02-26
      

            
      modify sgr/sgr0 in xterm-new to improve tgetent's
            derived "me".
      

            
      2006-02-18
      

            
      remove ncv flag from xterm-16color
      

            
      2006-06-24
      

            
      improve xterm-256color by combining the 16-color
            setaf/setab strings with SGR 48, and cancelling the
            setf/setb strings.
      
          
      
        
      • 

        
    • use extended function-key definitions for xterm-sun,
        xterm-sco entries.
      • 

        
    • add terminfo building-blocks corresponding to the
        modifyFunctionKeys and
        modifyCursorKeys resources.
      • 
      
    
    
    • 

    
  • ifdef'd Sun function-key feature to make it optional, like
    HP and SCO.
    • 

    
  • extend table for termcap-query feature through F63, and
    updated tcapquery.pl to match.
    • 

    
  • modify logic for function-key input processing to allow
    function key numbers which are constructed by control- and
    shift-modifiers to extend beyond X's hardcoded limit of
    35.
    • 

    
  • add control sequence to set or reset the
    eightBitInput resource.
    • 

    
  • change default resource modifyFunctionKeys to
    2 to avoid sending SS3 with parameters (report by Kalle Olavi
    Niemitalo).
    • 

    
  • add control sequences for setting and resetting the values
    of the modifyCursorKeys,
    modifyFunctionKeys and
    modifyOtherKeys resources.
    • 

    
  • add modifyFunctionKeys resource like
    modifyCursorKeys. Setting this to zero allows one
    to use the control- and shift-modifiers to construct function
    key strings, for terminals using many function keys, e.g., for
    xterm-sun or xterm-sco.
    • 

    
  • modify screen responses and function-key logic to reduce
    the number of writes made, to make it less likely that an
    application would read only part of a function-key in a read
    operation (suggested by John E Urbanczyk).
    • 

    
  • add combiningChars resource, which allows the
    user to specify the maximum number of combining characters that
    xterm will store for each cell in wide-character mode (prompted
    by request by Markus Kuhn to increase the limit from 2).
    • 

    
  • improve logic in metaSendsEscape in case the
    Alt- and Meta-keys are mapped to different modifiers. That
    allows one to use the Alt-key for shifting in the
    eightBitInput and use a Meta-key modifier to
    prefix the result with an <ESC>.
    • 

    
  • improve modifyCursorKeys logic to prevent it
    from modifying codes where eightBitInput or
    metaSendsEscape are set (request by Dan
    Nicolaescu).
    • 

    
  • improve modifyCursorKeys logic to prevent it
    from changing the user input when other modifiers such as AltGr
    are used (report by Thomas Wolff).
    • 

    
  • extend modifyCursorKeys to include the numeric
    keypad when in application mode.
    • 

    
  • improve -reverse (-rv) option
    (patch by Jason Vas Dias, Redhat #189161).
    • 

    
  • workaround for color resources on Fedora-5 which made the
    toolbar colors inconsistent.
    • 

    
  • corrected calls used for --disable-setuid
    option, add debugging traces to help diagnose this area.
    • 

    
  • modify configure script to ensure that
    USE_UTMP_SETGID is defined only if the check for
    POSIX saved-ids succeeds, or corresponds to one of the BSD
    systems known to have a workable setegid
    function.
    • 

    
  • extend configure check for POSIX saved-ids to include BSD
    systems
    • 

    
  • modify CF_SYSV configure macro to work with gcc on HPUX
    10.20, whose broken <term.h> relies on
    including <termios.h>.
    • 

    
  • change order of setuid/setgid ifdef checks in Imakefile to
    make it simpler to produce a setgid install, allowing the
    latter to override the former (prompted by an XFree86
    commit).
    • 

    
  • adapt a fix for setgid support from subsequent XFree86
    changes (patch by Emanuele Giaquinta).
    • 

    
  • further improve setgid support (patches by Emanuele
    Giaquinta).
    • 
  


  
Patch #215 - 2006/6/19 -
  XFree86 4.6.99.2


  
    
    
  • improve setgid support by exploiting the saved-ids feature
    on which it relies (patch by Emanuele Giaquinta).
    • 

    
  • make the modifyOtherKeys resource disabled by
    default since the intermediate setting altered some common
    bindings (report by Emanuele Giaquinta).
    • 
  


  
Patch #214 - 2006/6/18 -
  XFree86 4.6.99.2


  
    
    
  • modify makefile rule for ctlseqs.txt to strip
    backspace/overstrikes, and add a copy of ctlseqs.txt to the
    source tarballs (requests by Bram Moolenaar, Emanuele
    Giaquinta).
    • 

    
  • add modifyOtherKeys resource, analogous to the
    modifyCursorKeys resource. This applies to keys
    that normally would transmit nothing when a given modifier is
    applied (request by Dan Nicolaescu).
    • 

    
  • add default to the acceptable values for the
    keyboardType resource, allowing the
    -kt command-line option to override app-defaults
    resource settings of sunKeyboard, etc.
    • 

    
  • correct ifdef's for XkbBell() which used the
    header file but not the corresponding function in patch #175 (report by Zach Beane).
    • 

    
  • add xterm manpage to the --with-symlink
    logic.
    • 

    
  • regenerated configure script to omit some debugging
    artifacts of the SIGWINCH test.
    • 

    
  • fix install-man rule in
    Makefile.in to avoid including the
    $(DESTDIR) value in substitutions made on the
    manpages (patch by Emanuele Giaquinta).
    • 

    
  • improved fix for cursor deallocation (Redhat #186935, patch
    by Jason Vas Dias).
    • 

    
  • improve checks for setuid/setgid operation to accommodate
    limited resource management in some kernels (Gentoo
    #193238).
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #213 - 2006/4/30 -
  XFree86 4.5.99.905


  
    
    
  • minor optimization to cell layout; will use that to
    simplify some logic and allow for more than two combining
    characters in another patch.
    • 

    
  • add utf8Latin1 resource to make optional the
    feature from patch #209 which allowed
    ISO-8859-1 fonts to be used in cases where a wide font was
    given. This would only work for the special case where the user
    normally used Latin-1 and wanted some wide characters (report
    by Rostislav Krasny).
    • 

    
  • add utf8Title resource to manpage (Novell
    #52655).
    • 

    
  • fix typo in table entry for utf8Title resource
    which made it treated as an integer rather than boolean (patch
    by Mike Fabian, Novell #52655).
    • 
  


  
Patch #212 - 2006/4/9 -
  XFree86 4.5.99.904


  
    
    
  • improve description of forceBoxChars in
    manpage (discussion with Joe Wells).
    • 

    
  • set checkmark for "Select To Clipboard" menu entry on
    startup, from resource setting.
    • 

    
  • update manpage to note that
    *customization:color is not needed, though it is
    useful (Redhat #188034).
    • 

    
  • add underscore to sample pattern for URL in
    XTerm.ad (Redhat #188037).
    • 

    
  • modify install rule for manpage to use the configured
    app-defaults directory (Redhat #188031).
    • 

    
  • add checks in releaseCursorGCs() to ensure
    GC's are distinct, needed since memory leak changes for
    patch #208 (Redhat #186935, patch by
    Jason Vas Dias).
    • 

    
  • modify Imakefile definitions to allow
    imake to set InstallXtermSetGID. Add
    symbol InstGidFlags.
    • 

    
  • add configure script check to ensure that SIGWINCH if
    defined even when headers undefine this as a side-effect of
    _POSIX_C_SOURCE, etc.
    • 

    
  • resync with XFree86 CVS

      
      
        
    • ifdef-out chmod of terminal device for OS/2 (XFree86
        #1663, Frank Giessler).
      • 

        
    • move new Imakefile chunk which defines
        $(CSGIDFLAGS) before DEFINES, e.g., for IRIX64
        (Marc La France).
      • 
      
    
    
    • 
  


  
Patch #211 - 2006/3/19 -
  XFree86 4.5.99.902


  
    
    
  • modify prefix/suffix transformation in makefile to make
    uxterm install properly on Cygwin.
    • 

    
  • restore the sizeof-comparison for struct
    lastlog added in patch #208,
    rendered (mostly) obsolete in patch
    #210, since an imake configuration can still turn that code
    on (prompted by comment by David Dawes).
    • 

    
  • remove feature for FreeBSDArchitecture from
    Imakefile which would install xterm using the
    utmp group since a standard FreeBSD system has no
    such group, though it would support this configuration. FreeBSD
    packager uses the configure script, which can make
    the appropriate check (prompted by comment by David
    Dawes).
    • 

    
  • fixes for gcc redefinition warnings when built using imake
    (reports by David Dawes, Marc La France).
    • 
  


  
Patch #210 - 2006/3/12 -
  XFree86 4.5.99.902


  
    
    
  • add configure check for workaround in patch #208 for Solaris' inconsistent support
    for struct lastlog to quiet compiler warnings (prompted by
    David Dawes commit message for XFree86).
    • 

    
  • fixes for BASE64 selection manipulation, e.g., ensure that
    the string terminator is written after cut-buffer data (report
    by Joe Allen).
    • 

    
  • add vttests/paste64.pl script to test experimental option
    for setting/getting selection data.
    • 

    
  • add some error-checking in fontutils.c (prompted by David
    Dawes commit message for XFree86).
    • 

    
  • change xterm manpage to show the actual color resource
    names XtDefaultForeground and
    XtDefaultBackground rather than black and white
    (prompted by discussion with Emanuele Giaquinta).
    • 

    
  • add utf8Title resource and menu entry,
    allowing the user to control whether title strings are
    interpreted as ISO-8859-1 or UTF-8 encoding (Novell #52655,
    Novell #113206).
    • 

    
  • change order of ifdef's for utempter versus platforms in
    Imakefile to ensure a proper value for
    InstallXtermSetGID (prompted by Marc La France
    commit message for XFree86).
    • 

    
  • update the cursor GCs when menu entry for reverse video is
    toggled. (Redhat #183993).
    • 

    
  • a memory-leak fix for set_cursor_gcs() in
    patch #208 broke the -cm
    option (Redhat #182382).
    • 
  


  
Patch #209 - 2006/2/12 -
  XFree86 4.5.99.22


  
    
    
  • remove setf and setb from
    xterm-256color terminfo entry to avoid issues with
    applications that ignore the ANSI strings (report by Emanuele
    Giaquinta).
    • 

    
  • remove obsolete references to "Xorg" to avoid confusion
    with "X.org" (prompted by David Dawes commit message for
    XFree86).
    • 

    
  • improve initial layout performance for the toolbar
    configuration by precalculating the height of the toolbar.
    • 

    
  • remove menu entry for "Enable Curses Emulation" (to make
    room for "Select To Clipboard").
    • 

    
  • add resource selectToClipboard, action
    set-select and a menu entry to allow users to
    switch between PRIMARY and CLIPBOARD for select/paste.
    • 

    
  • allow cursor to have the same color as foreground (text),
    since it is rendered as reverse (Debian #350664).
    • 

    
  • amend change for loading utf8Fonts resource
    from patch #204 to allow an ISO-8859-1
    "normal" font to be combined with an ISO-10646 font if the
    latter is given via the -fw option or its
    corresponding resource value (prompted by comment in Novell
    #49305).
    • 

    
  • add TIOCSCTTY ioctl() ifdef'd for
    __GNU__ to set the controlling terminal (Debian
    #348457).
    • 

    
  • add configure option --disable-leaks.
    • 

    
  • add a check in Bell to ensure that the VT100
    widget is realized, since it may be called by
    xtermLoadFont given an incorrect font resource
    (Redhat #180450).
    • 

    
  • improve initialization of wide-bold font by not using the
    derived value when it happens to have few glyphs (report by
    Mboso Sampson).
    • 

    
  • improve dynamic colors by not repainting the screen if only
    the cursor color changes (request by Bram Moolenaar).
    • 

    
  • fix menu initialization for tek4014 window broken in
    patch #206.
    • 

    
  • typo in manpage (Debian #351425).
    • 

    
  • correct loop logic in dotext to prevent an
    infinite loop if a wide character was just at the right margin
    when wrapping was disabled (report by Serge van den Boom).
    • 

    
  • initialize the saved-cursor data so a restore-cursor
    operation without a preceding save-cursor operation will not
    modify the foreground color.
    • 

    
  • add a new selection feature: regular expressions, and new
    resources which specify what happens on multiple mouse clicks:
    on2Clicks, on3Clicks,
    on4Clicks and on5Clicks.
    • 

    
  • revert the XTerm.ad change from patch #208 (Debian #348384).
    • 

    
  • fixes for the print-window to make it handle combining
    characters in UTF-8 mode.
    • 

    
  • add check to ensure that double-clicking to extend
    selection will not extend it into the scrollback area. This
    still allows users to scroll back and select text (Debian
    #347415).
    • 

    
  • add configure option --with-tty-group to help
    work around deficiencies in packager's build environment
    (Debian #349142).
    • 

    
  • fix typo in configure script option
    --disable-narrowproto (report by David
    Martínez Moreno).
    • 

    
  • amend CF_X_FREETYPE changes for pkg-config
    check to ensure that Xft is known to that tool
    (report and patch by Emanuele Giaquinta).
    • 

    
  • add an ifdef to allow ./configure
    --disable-active-icon to work, broken by new code for
    testing memory leaks in patch #208
    (report by Brian Lindholm).
    • 
  


  
Patch #208 - 2006/1/3 -
  XFree86 4.5.99.19


  
    
    
  • add charClass resource to
    XTerm.ad and UXTerm.ad which
    simplifies selecting URLs (prompted by Kirill Ponomarew).
    • 

    
  • modify install rule for uxterm to account for
    the --program-prefix, etc., options by invoking
    the transformed name of xterm rather than simply "xterm".
    • 

    
  • modify configure --with-app-defaults option to
    allow --without-app-defaults.
    • 

    
  • add configure --with-symlink option to make it
    simpler to install successive versions of xterm
    renamed using the --program-prefix, etc., options
    with a symbolic link pointing to the most recent.
    • 

    
  • make -iconic option work with toolbar
    configuration (Gentoo #113604).
    • 

    
  • suppress lastlog feature for 64-bit Solaris
    configuration since that platform provides only a 32-bit
    interface (report by Peter Bray).
    • 

    
  • fix memory reallocation for the "UTF-8" menu entry when
    xterm is started using the +u8 option (reported by
    Jan Willem Stumpel).
    • 

    
  • add a configure check for the actual path of
    luit, to work around broken imake
    configurations.
    • 

    
  • add a configure check for pkg-config (Redhat
    Bugzilla #173541).
    • 

    
  • modify install-rule for uxterm to omit
    executable suffix, e.g., for Cygwin.
    • 

    
  • modify sinstall.sh to work around quirks in
    Cygwin configuration.
    • 
  


  
Patch #207 - 2005/11/13 -
  XFree86 4.5.99.16


  
    
    
  • enable lastlogx support for NetBSD (was added,
    but not enabled in patch #186).
    • 

    
  • work around broken lastlog.h in glibc 2.3.5,
    which includes utmp.h.
    • 

    
  • revert part of recent XFree86 Imakefile change, restoring
    the -I. needed for xmkmf builds of
    xterm (XFree86 Bugzilla #1633, reports by Alexander Pohoyda,
    Matthieu Herrb).
    • 

    
  • change compiled-in default for printerCommand
    resource to an empty string. People who want to use the printer
    should be able to read the manual (Debian #311490).
    • 

    
  • modify Imakefile to work around old problems
    in imake configuration to allow test-builds using
    xmkmf on Linux. (This was not noticed since
    several releases had broken definitions relating to Xft which
    were harder to work around).
    • 

    
  • link resize for SCO platforms (Kean
    Johnston).
    • 
  


  
Patch #206 - 2005/11/3 -
  XFree86 4.5.99.15


  
    
    
  • add configure --with-app-defaults option to
    allow app-defaults directory for install-rules to be
    customized.
    • 

    
  • remove default translations for
    dabbrev-expand() due to conflicts with existing
    keyboard arrangements.
    • 

    
  • remove redundant check for _NET_WM_PID (report
    by Emanuele Giaquinta).
    • 

    
  • set icon border width explicitly to work around fvwm
    problem with active icon resizing (report by Steve Morris,
    analysis by Dominik Vogt).
    • 

    
  • modify resource files to make the font-resources a little
    more specific, e.g., changing "*VT100*" to "*VT100.", to make
    the distinction between VT100.font and VT100.utf8Fonts.font
    sharper, in case a packager modifies one of those.
    • 

    
  • expanded comments in UXTerm.ad regarding the
    font resources (Debian #319179).
    • 

    
  • add --enable-narrowproto configure option to
    accommodate X.org "modular" build (report by Stephan Hermann,
    Gentoo #17220).
    • 

    
  • fix typo in xterm.man description of +wf
    (patch by Tobias Stoeckmann).
    • 

    
  • add scrollBarBorder resource (request by Floyd
    L Davidson).
    • 

    
  • modify xterm-new terminfo entry to use
    capabilities for shifted scroll forward/reverse as shifted
    cursor up/down.
    • 

    
  • correct updating of checkmark for toolbar entry in popup
    menu (report by Emanuele Giaquinta).
    • 

    
  • fix ifdef's to allow compiling with toolbar and without
    tek4014 (patch by Emanuele Giaquinta).
    • 

    
  • use openpty() for Darwin port (patch by
    Emanuele Giaquinta).
    • 

    
  • fix Gentoo #90697 a different way, postponing the logic in
    SetupToolbar until the toolbar is actually needed,
    i.e., the +tb option is handled as expected.
    • 

    
  • revert fix made in patch #203 for
    Gentoo #90697. That introduced a problem with the control mouse
    click-popups, while most of the performance problems can be
    resolved by restricting the menu fonts (report by Emanuele
    Giaquinta).
    • 

    
  • fix a file-descriptor leak when calling
    openpty() (OpenBSD system/4561).
    • 

    
  • make a special case of resizing work like vt100: a hard
    reset also resets the 132/80 mode. The code to support this was
    present since X11R5, but not used because the corresponding
    initial state of the -132 option was not
    saved.
    • 

    
  • restore window manager hints after
    XtMakeResizeRequest() calls. One instance from
    patch #205 resulted in the window
    manager displaying pixels rather than than characters after
    selecting a different font size (FreeBSD ports/87424).
    • 

    
  • remove special case for Darwin in CF_XOPEN_SOURCE (Emanuele
    Giaquinta).
    • 

    
  • modify parsing of control sequence CSI T
    to allow scroll-down to be sent while mouse tracking is enabled
    (request by D Hugh Redelmeier).
    • 

    
  • correct termcap "me" (mode-end) string so it does not
    modify the alternate character set (report by Andrey
    Chernov).
    • 

    
  • correct size-comparison in HandleInterpret() broken in
    changes from patch #201 to allocate
    input buffer (Debian #334317).
    • 

    
  • amend adjustments for scrollbar layout from patch #204 to make this apply only to the
    toolbar configuration. In the non-toolbar configuration, the
    resulting scrollbar was shifted by its borderwidth (report by
    Matthieu Herrb).
    • 

    
  • add select-cursor-extend() action.
    • 

    
  • fix some broken href's in xterm.log.html, and typo in the
    INSTALL file (report/patch by David Martínez
    Moreno).
    • 

    
  • modify Imakefile to use setgid mode for
    installing with Linux, OpenBSD and FreeBSD.
    • 

    
  • add configure --with-setuid and --with-reference options to
    allow packagers more flexibility in customizing install
    permissions.
    • 

    
  • generalize and make optional (configure --with-utmp-setgid)
    the change made for XFree86 Bugzilla #878 in patch #205 (FreeBSD bug report
    #ports/86663).
    • 
  


  
Patch #205 - 2005/9/18 -
  XFree86 4.5.99.12


  
    
    
  • correct a typo in CF_FUNC_TGETENT introduced in patch #198 fix for Gentoo #69926.
    • 

    
  • implement logic in termcap query to process multiple
    parameters as documented in ctlseqs.ms
    • 

    
  • fix buffer size used for termcap query, which was not long
    enough for the terminfo "colors" name (patch by Bradd W.
    Szonye).
    • 

    
  • add configure option --enable-readline-mouse, which turns
    on the experimental OPT_READLINE code (patch by Ilya
    Zakharevich).
    • 

    
  • for FreeBSD, drop setuid privileges after startup (XFree86
    Bugzilla #878, report/patch by Alexander Pohoyda)
    • 

    
  • add menu entry (alt-esc) and corresponding action
    (alt-sends-esc) to toggle the eightBitInput
    resource setting.
    • 

    
  • generate configure script with autoconf 2.52 (patched) to
    use the feature therein which forces the script's locale to
    POSIX (Gentoo Bugzilla #105369).
    • 

    
  • modify computation of rows/columns on resize to avoid
    extending beyond the given limits, e.g., if resizing in
    response to a "maximize" in Gnome or KDE which do not use the
    window manager hints for this case (Debian #289123, Novell
    #61153).
    • 

    
  • modifications to work with z/OS 1.4 (Paul Giordano).
    • 

    
  • improve error-reporting when chown/chmod of the
    pseudo-terminal fails, e.g., if a copy of xterm which was
    designed to work with old-style pseudo-terminals is not
    installed setuid or setgid (report by Jeremy C. Reed).
    • 

    
  • patches from Emanuele Giaquinta:

      
      
        
    • ctlseqs.ms says that primary and secondary DA accept a
        nonzero parameter, which is incorrect. Also modify code to
        agree with this.
      • 

        
    • correct a comment in 88colres.pl
      • 

        
    • ctlseqs.ms says that the DEC Set/Reset control
        sequences for the backarrow key make it send DEL/BS,
        respectively, while it's the opposite.
      • 

        
    • update the menu entries for the metaSendsEscape,
        deleteIsDEL and numLock resources when changing them with
        the corresponding DEC Set/Reset control sequences.
      • 
      
    
    
    • 

    
  • fixes for configure script:

      
      
        
    • add special case for QNX, defining _QNX_SOURCE.
      • 

        
    • check for preprocessors which do not perform -U and -D
        options in the given order.
      • 

        
    • improve macro to determine gcc version
      • 

        
    • improve check for Intel compiler and related warning
        options
      • 
      
    
    
    • 

    
  • update config.guess, config.sub
    • 

    
  • improve fix from patch #198 for
    Cleanup() by ensuring it is not called from the
    SIGCHLD handler (patch by Todd Miller (OpenBSD CVS)).
    • 

    
  • eliminate a retry for a better-matching bold font, to work
    around recent font server changes.
    • 

    
  • fixes for Novell #113277:

      
      
        
    • specify weight for wide font which may be derived from
        normal fontname.
      • 

        
    • cache the derived wide- and widebolt-fontnames.
      • 
      
    
    
    • 

    
  • workaround for Gentoo Bugzilla #100728.
    • 

    
  • add menubar's border width to layout computation. Normally
    this is zero, but patterns such as
    XTerm*borderWidth:1 would give poor layout for the
    toolbar configuration.
    • 
  


  
Patch #204 - 2005/8/4 -
  XFree86 4.5.99.9


  
    
    
  • work around quirk in shell which allowed user to "run"
    uxterm script when there was no UTF-8 locale installed by
    entering "sh -x uxterm". Also popup an xmessage to show the
    problem for users who run this via a GUI (Debian #318513).
    • 

    
  • disallow changes to fonts, toolbar and scrollbar when the
    vt100 window is iconified, to simplify management of the active
    icon.
    • 

    
  • fixes to make -geom option work properly with
    the toolbar configuration (Gentoo #90717, Gentoo #91967).
    • 

    
  • minor improvements to scrollbar layout: ensure that the
    scrollbar border is zero if the vt100 border is zero.
    • 

    
  • improve initialization due to utf8 resource by
    loading the utf8Fonts resource in the case where
    locale resource is false. Also in this case, do
    not disable switching UTF-8 mode on/off.
    • 

    
  • minor optimization of TrueType font-loading, loads italic
    font only when needed.
    • 

    
  • correct variable used to store temporary result from lookup
    of bold font, when initializing the wide-bold-font data and no
    immediate match is found by asking for a bold variant of the
    wide-font. The result was to use overstriking rather than the
    actual bold font (Debian #318162, patch by Eugene Konev).
    • 

    
  • add checks to ensure vt100 widget is realized when it might
    be updated via actions handled from a tek4014-only
    configuration.
    • 
  


  
Patch #203 - 2005/7/6 -
  XFree86 4.5.99.7


  
    
    
  • modify initialization of allowSendEvents and
    allowWindowOps to prevent modification with the
    editres protocol.
    • 

    
  • fix compiler warning for NetBSD by including util.h in
    main.c (XFree86 Bugzilla #1596).
    • 

    
  • fix to build on Darwin 8.x, which no longer provides
    setpgrp() (patch by Min Sik Kim).
    • 

    
  • adapted fixes for Legend (SCO) from diffs attached to
    Freedesktop.Org Bugzilla #3180.
    • 

    
  • fix typo in xterm manpage description of -ls
    option (Freedesktop.Org Bugzilla #3543).
    • 

    
  • add support for interpreting the underline attribute as an
    italic font in Xft mode (patch by Chuck Blake).
    • 

    
  • improve initialization of toolbar so that individual
    pulldown menus are initialized on demand, as they are in the
    scenario where they are invoked as popup menus (Gentoo Bugzilla
    #90697).
    • 

    
  • fix logic in find_utmp, which did not reset
    result in getutid(), causing an infinite loop in
    some conditions (report by Emil Mikulic).
    • 

    
  • set the _NET_WM_PID property (Gentoo Bugzilla
    #91008).
    • 

    
  • modify ifdef's in ptyx.h and xterm_io.h to build with
    DragonFly (patch by Jeroen Ruigrok).
    • 

    
  • change default values for minBufSize and
    maxBufSize to 4096 and 32768 respectively so that
    the initial read request will match the value from before
    changes to use sched_yield().
    • 

    
  • make paste of UTF-8 faster for Western character sets by
    checking range of incoming data (patch by Joe Allen).
    • 

    
  • add experimental option to allow applications to get or set
    the selection data as a BASE64 string (adapted from patch by
    Joe Allen).
    • 

    
  • fix an off-by-one error parsing -S/nn option
    (Debian #311438, report/fix by Peter Chubb).
    • 

    
  • fix an initialization bug from patch
    #201 that broke logging (report by Rodney Thayer).
    • 

    
  • amend change to command-line processing in patch #201 to avoid conflict with
    -e option (report by Servatius Brandt).
    • 

    
  • suppress configure check for _XOPEN_SOURCE on
    darwin.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #202 - 2005/5/2 -
  XFree86 4.5.99.3


  
    
    
  • add extended shift- and control-modifier cursor keys to
    "xterm+pcfkeys" terminfo entry to correspond to ncurses
    20050430 patch.
    • 

    
  • fix a rare case where text would be written with the wrong
    colors because output of scrolled text would reset the colors
    and the new text would be written with the same colors
    (report/testcase by Thomas Glanzmann).
    • 

    
  • rename $CMD variable in plink.sh
    because it is a reserved symbol in bash 3.00.16 (report by Ted
    Taylor).
    • 

    
  • add environment variables $XTERM_SHELL and
    $XTERM_VERSION (request by Zdenek Sekera).
    • 

    
  • corrected workaround for background color of menubar, which
    gave a too-broad expression, coloring the background of the
    VT100 widget unless overridden by another resource
    setting.
    • 

    
  • correct an error in the logic which decides when
    sched_yield() is run; it would occasionally hang
    when contending with other pseudo-terminal applications such as
    screen (report by Kirill Ponomarew).
    • 

    
  • modify initialization to decide whether to default to
    built-in wcwidth() versus system's version based
    on the starting locale and whether the system's version is poor
    quality (suggested by Bram Moolenaar).
    • 

    
  • update table for mk_width() from UnicodeData
    4.1.0 using Markus Kuhn's uniset script.
    • 
  


  
Patch #201 - 2005/4/21 -
  XFree86 4.5.99.2


  
    
    
  • improve resource files to show how the menubar and popup
    menus can be colored (prompted by report by Joe Wells).
    • 

    
  • modify parsing of OSC (and SOS, etc), strings so their
    contents are not interpreted as UTF-8. This allows non-ASCII
    title strings to be set, provided that the window manager
    complies (report by Thomas Wolff).
    • 

    
  • improved some of the built-in line-drawing glyphs.
    • 

    
  • correct color of "box" character drawn for line-drawing
    glyph 1 (report by Nicolas George).
    • 

    
  • improve behavior when switching to UTF-8 mode after startup
    so xterm will check if the current fonts are already wide
    (ISO10646-1). If they are not, xterm will use the
    utf8Fonts subresource to load appropriate fonts
    (request by Bram Moolenaar).
    • 

    
  • modify logic for setting title-string so it applies to the
    current widget rather than the vt100 widget.
    • 

    
  • modify initialization for wide-bold fontname, to search for
    one if none is given (report by Michael Schroeder).
    • 

    
  • add resource mkWidth and command-line option
    -mk_width to control whether xterm uses the
    built-in version of wcwidth().
    • 

    
  • add resource settings for minimum/maximum input buffer
    size, and call to sched_yield to improve
    performance with newer Linux kernels (adapted from patch by
    Nicolas George).
    • 

    
  • correct computation of width for wide characters with the
    invisible attribute (report by Thomas Wolff).
    • 

    
  • modify interaction between +u8 and
    locale resource to allow the command-line option
    to override the resource (requested by Thomas Wolff).
    • 

    
  • add a limit check for scrolling margins in a one-line
    screen, overlooked in fixes for patch
    #198 (Debian #297430).
    • 

    
  • correct treatment of iconBorderWidth for
    resizing an active-icon, and its description in manpage (Debian
    #296592).
    • 

    
  • modify configure script --disable-imake to use
    the script's definitions anyway if it cannot detect imake
    (prompted by FreeBSD bug 77408).
    • 

    
  • ignore error in the I/O initialization that tries to set
    the tty to 7-bit input for the case where
    eightBitInput resource is false (Debian
    #298551).
    • 

    
  • modify command-processing to accept an optional parameter
    that tells xterm which shell program to use (request by Zdenek
    Sekera).
    • 

    
  • add simpler resource keyboardType which, when
    set, overrides the individual keyboard-type resources and
    eliminates the possibility of conflict between them.
    • 

    
  • add initialization for scoFunctionKeys
    resource (report by Rick K).
    • 

    
  • correct logic of ReallocateBufOffsets() which
    did not copy the content of the old screen buffer to the proper
    location, making a repaint clear after switching to
    wide-character mode (report by Bram Moolenaar):
    • 

    
  • implement the remaining pieces to make xterm allocate cells
    for wide-characters when the "UTF-8" menu entry is selected.
    Also, load the UTF-8 font when that menu entry is selected, or
    the escape sequence for UTF-8 mode is received (report by Bram
    Moolenaar):
    • 

    
  • add command-line options (-tb,
    +tb) and resource toolBar to allow
    menu/toolbar to disabled or enabled at startup (prompted by
    reports by Joe Wells).
    • 

    
  • correct typo in configure script's --enable-dec-locator
    option (report by Bram Moolenaar).
    • 
  


  
Patch #200 - 2005/2/6 -
  XFree86 4.4.99.23


  
    
    
  • increase color pairs value for xterm-256color and
    xterm-88color to match ncurses, which has an experimental
    option to support this.
    • 

    
  • modify ifdef's to make AIX use termios rather than termio;
    the struct sizes for the two were not the same.
    • 

    
  • improve CF_WITH_IMAKE_CFLAGS configure macro script for
    OSMAJORVERSION and OSMINORVERSION values, e.g., for Tru64 and
    AIX.
    • 

    
  • modify ifdef to define USE_POSIX_TERMIOS for Darwin (patch
    by Min Sik Kim).
    • 

    
  • modify find_utmp() to initialize the whole utmpx struct
    (except ut_id), since that is needed for OSF1 4.0D to prevent
    an infinite loop on exit.
    • 

    
  • add configure check before adding -D_POSIX_SOURCE since
    some platforms predefine it, e.g., cygwin.
    • 

    
  • add simplified sed expressions in CF_IMAKE_CFLAGS configure
    script macro to ensure value for PROJECTROOT is quoted on
    Solaris, i.e., when nested \( and \)
    are not interpreted correctly.
    • 

    
  • correct DEC rectangle operations to reset state after
    completing the operations.
    • 

    
  • modify CASE_ST handling in charproc.c to ensure that the
    parse state is reset even if xterm is not currently processing
    an OSC or other string (patch by Johnny Billquist forwarded by
    Matthias Scheler, NetBSD xsrc/29003).
    • 

    
  • fix OS/2 build for innotek_libc (patch by David Yeo).
    • 

    
  • fix a regression from patch #197
    fix for Debian #277832 which disowned the selection if it was
    scrolled, e.g., by the user pressing return at the bottom of
    the screen (Debian #291787).
    • 

    
  • move the warning/exit for missing $DISPLAY into the error
    handler in case -display is given, and the connect
    fails for some other reason.
    • 
  


  
Patch #199 - 2005/1/17 -
  XFree86 4.4.99.22


  
    
    
  • instead of setting $DISPLAY, check for the
    unset variable and warn/exit on this condition (comments by H
    Merijn Brand and Bernhard R Link).
    • 

    
  • fix a typo in Imakefile from patch
    #198 (reports/patches by Stefan Dirsch, Mike Castle).
    • 
  


  
Patch #198 - 2005/1/13 -
  XFree86 4.4.99.21


  
    
    
  • set $DISPLAY to ":0" if it is not set.
    • 

    
  • add utmpDisplayId resource to allow users to
    control whether the display identifier (display number and
    screen number) are retained in the connection information
    recorded in utmp (discussion with Edoardo Tirtarahardja).
    • 

    
  • add bellOnReset resource to allow users to
    disable bell which sounds on hard reset since patch #183 changes to DECSCL (discussion with
    Danek Duvall).
    • 

    
  • improve $WINDOWID for configuration with
    toolbar by making it refer to the top-level shell rather than
    the parent of the current window. For that case, the parent is
    a form widget, which does not have a name, which made the
    $WINDOWID not very useful as a parameter for
    xwininfo (suggested by Dave Bodenstab).
    • 

    
  • fix a typo in WhichVFont() macro from patch #197 changes which broke the
    --disable-active-icon configuration (report by Ralf S.
    Engelschall).
    • 

    
  • improve some limit checks (Gentoo Bugzilla #75604).
    • 

    
  • add --disable-setuid option to configure script (Gentoo
    Bugzilla #76543).
    • 

    
  • add --disable-full-tgetent option to configure script,
    allowing one to ignore a termcap library in favor of
    ncurses/curses (Gentoo Bugzilla #69926).
    • 

    
  • modify configure script to choose useful warning options
    for Intel version 8.0 compiler.
    • 

    
  • update config.guess, config.sub
    • 

    
  • make active-icon work properly when TrueType fonts are used
    (Debian #286068).
    • 

    
  • correct change from patch #157
    which uses getlogin() to check for an alias; the storage used
    for the related getpwuid() call was overwritten by the data
    used for comparison (patch by Per Hedeland).
    • 

    
  • correct case of SCS for character set 0 (line-drawing) to
    allow it to be selected into GR.
    • 

    
  • fix a file-descriptor leak (Redhat Bugzilla #139597).
    • 

    
  • modify creat_as() to only fork if xterm is
    actually running as setuid and/or setgid. This works around a
    Cygwin bug which hangs when logging is enabled and makes xterm
    a little faster for systems using interfaces such as utempter
    (report by Al Goodman).
    • 

    
  • modify Cleanup() to avoid operations such as X
    calls that might use unsafe functions when it is called by a
    signal handler (report by Michiel Boland).
    • 

    
  • fix bugs in patch #191 and in SRM
    changes from patch #197 that broke
    DECSET 38: switch to Tek4014 emulation (report by Dave
    Bodenstab).
    • 

    
  • fix for manpage escapes (Marc La France).
    • 

    
  • improve on IRIX-specific change for Imakefile in XFree86
    CVS versus resize linking against termcap library to reflect
    definitions for USE_TERMCAP in resize.c
    • 
  


  
Patch #197 - 2004/11/30 -
  XFree86 4.4.99.19


  
    
    
  • modify configure script to remove empty "-DPROJECTROOT="
    definition which resulted unusable values for luit's default
    path.
    • 

    
  • update precompose.c based on Unicode 4.0.1
    • 

    
  • several minor fixes based on Intel compiler warnings.
    • 

    
  • change default translations so a BtnDown which
    is not recognized is simply ignored rather than emitting a
    bell. That makes it less obtrusive when the user tries to use a
    mouse which provides more capabilities than the X mouse driver
    supports, e.g., one with a horizontal scroll wheel (Debian
    #265133).
    • 

    
  • note in xterm's manpage that translations is
    not specific to xterm (Debian #278897).
    • 

    
  • modify uxterm script to use locale program to verify if the
    derived locale is installed (Debian #246398).
    • 

    
  • correct font handling for active icon when in UTF-8 mode
    (report by Paolo Liberatore).
    • 

    
  • make active-icon and toolbar configurations work
    together.
    • 

    
  • modify the criteria for disowning primary selection.
    Previously, this happened anytime the cursor was moved before
    the end of the selection. That would ensure that any
    insert/delete of char or line, as well as scrolling, would
    disown the selection. The new criteria change this to checking
    if the operations would modify the data which is highlighted
    (Debian #277832).
    • 

    
  • reimplement DECALN with functions for vt420
    rectangles, fixes selection for this case.
    • 

    
  • implement vt420 rectangle operations.
    • 

    
  • add parsing, for debug/test of vt220 soft-fonts.
    • 

    
  • add menu entry, actions and escape sequence to allow
    enabling/disabling toolbars at runtime.
    • 

    
  • improve rendering for Xft, allow it to draw non-linedrawing
    characters such as "pi", which were drawn from internal tables
    with patch #180 (Freedesktop.org
    Bugzilla #1260).
    • 

    
  • add configure option --enable-mini-luit,
    ifdef'd the mini-luit feature with
    OPT_MINI_LUIT.
    • 

    
  • add mini-luit feature, which supports Latin9 directly
    rather than via luit, provided that Unicode fonts are used
    (Freedesktop.org Bugzilla #1571, request by Stefan Dirsch,
    patch by Michael Schroeder).
    • 

    
  • for Linux, if IUTF8 is defined, e.g., on recent 2.6.x
    kernels, set the corresponding flag for the slave pty, to
    enable UTF-8 interpretation of backspace in cooked mode
    (Freedesktop.org Bugzilla #1578, request by Stefan
    Dirsch).
    • 

    
  • modify faceSize resource to use a
    floating-point internal value (adapted from patch by Sam
    Stephenson).
    • 

    
  • correct handling selection of tabs over cleared space in
    UTF-8 mode. In this special case, xterm represents the
    whitespace with a null rather than a space character (Debian
    #276447).
    • 

    
  • amend fix for infinite loop from patch
    #192 to check if there is wrapped text to output in a
    following iteration (Debian #273202).
    • 

    
  • fixes ifdef'd with __INTERIX to allow building
    with Interix (Windows Services for UNIX) 3.5 using the xlibs
    libraries from freedesktop.org (patch by Min Sik Kim).
    • 

    
  • amend solution for Debian #252873, Debian #260471 from
    patch #194 by making the cursor not
    explicitly colored if only the foreground color is set, and the
    cursor is on a blank space (Debian #275473).
    • 

    
  • correct logic for send/receive mode (SRM) with regard to
    control characters.
    • 

    
  • fix masking of invisible text in wide-character mode, which
    did not work for line-drawing characters.
    • 

    
  • incorporate CF_XOPEN_SOURCE into configure script,
    replacing CF_GNU_SOURCE.
    • 
  


  
Patch #196 - 2004/8/15 -
  XFree86 4.4.99.12


  
    
    
  • add a special case to configure script to ignore NetBSD's
    grantpt() which was recently added (but not part
    of a release), until someone is able to ensure that xterm can
    use it (report by Min Sik Kim).
    • 

    
  • clear the buffer returned by getutid(). This fixes an
    infinite loop on some platforms introduced in patch #193 by Debian #256468 fix (report by
    David Ellement).
    • 
  


  
Patch #195 - 2004/8/8 -
  XFree86 4.4.99.11


  
    
    
  • correct length used for blinking text, make the last column
    blink (patch by Alexander V Lukyanov).
    • 

    
  • start changes to make doublesize characters work with
    TrueType fonts (see patch #44).
    • 

    
  • trim leading/trailing blanks from color resources as done
    for other strings in patch #167.
    • 

    
  • fixes for showBlinkAsBold resource (report by
    Christoph Berg).
    • 
  


  
Patch #194 - 2004/7/27 -
  XFree86 4.4.99.11


  
    
    
  • change clearing operations so foreground color attribute is
    not set. Usually this is benign, but in some cases when the
    cursor color is not set explicitly, the cursor would show this
    color (Debian #252873, Debian #260471).
    • 

    
  • add extra state (cursor-moved) to guard against deciding
    that the cursor did not require repainting after an indexing
    operation that leaves the cursor in the same location on the
    screen.
    • 

    
  • fix a case where a full-screen indexing operation would not
    restore the cursor-busy state.
    • 

    
  • fix a repainting bug introduced in patch #180: when using a font lacking
    line-drawing characters, a repaint of the screen could skip
    horizontally an extra amount after filling in the missing
    character (reports by Nicolas George, Hans de Goede, Redhat
    Bugzilla #128341).
    • 

    
  • rename terminfo fragment "xterm-pc-fkeys" to
    "xterm+pcfkeys" for consistency with ncurses.
    • 
  


  
Patch #193 - 2004/7/19 -
  XFree86 4.4.99.10


  
    
    
  • fix for wide-character selection from OpenBSD CVS
    (report/patch by Matthieu Herrb).
    • 

    
  • modify initialization and cleanup of utmp data to also
    compare the ut_line member (Debian #256468).
    • 

    
  • modify check on focus-change to ignore
    FocusOut events generated by
    XGrabKeyboard. This fixes a case where the text
    cursor would act as if focus were lost when selecting the
    "Secure Keyboard" menu option.
    • 

    
  • add gen-pc-fkeys.pl script, use that to
    generate terminfo fragment corresponding to the pc-style
    function keys.
    • 

    
  • fix a case where the checkmark by the "VT220 Keyboard" menu
    entry was not set on startup.
    • 

    
  • separated two methods for making the cursor blink (menu and
    escape sequence) by using the menu as the primary method and
    XOR'ing the state of the escape sequence against that.
    • 

    
  • modify logic for enabling blinking cursor via escape
    sequence as well as the related save/restore operations so this
    is only available if the cursorBlink resource was
    set on startup.
    • 
  


  
Patch #192 - 2004/7/12 -
  XFree86 4.4.99.9


  
    
    
  • change resource settings for color4 and color12, add some
    discussion in XTerm-col.ad (Debian #241717).
    • 

    
  • add a note in xterm manpage discussing the difference
    between alt- and meta-keys, and the way the latter is used in
    the eightBitInput resource.
    • 

    
  • add a note in xterm manpage regarding possible conflict
    between resource settings for xterm.vt100.font and
    xterm.vt100.utf8Fonts.font (Debian #254650).
    • 

    
  • add compile-time customization of
    backarrowKeyIsErase and
    ptyInitialErase default resource values (adapted
    from OpenBSD CVS).
    • 

    
  • change parameter of FIONREAD
    ioctl() call from long to int (discussion on
    tech-x11@netbsd.org regarding LP64 by John Heasley and Matthias
    Scheler).
    • 

    
  • modify configure script options for Athena widgets to work
    as expected for "--without-Xaw3d", etc., (Gentoo Bugzilla
    #53455).
    • 

    
  • add case to uxterm to accommodate locales ending with
    "@euro", e.g., fr_FR.UTF-8@euro (Debian #255197,
    report/analysis by Matthieu Lagouge).
    • 

    
  • add special case for VT100 graphic's "box" character
    (discussion with Ben Armstrong).
    • 

    
  • add missing initialization for bitmap-font sizes needed to
    make fonts menu work with TrueType fonts (report by Ben
    Armstrong).
    • 

    
  • save the fontnames for bold fonts that are derived from
    normal fonts, or from the boldFont resource, so
    the same value is restored when switching with the VT Fonts
    menu (Debian #256086).
    • 

    
  • fix manpage preprocessing (Marc La France).
    • 

    
  • fix typo in manpage's description of character classes
    (Debian #257073).
    • 

    
  • modify terminfo to accommodate luit, which relies on G1
    being used via an ISO-2022 escape sequence (Debian #254316,
    analysis by Juliusz Chroboczek).
    • 

    
  • modify Makefile.in rule for ctlseqs.txt to work around
    groff SGR misfeature.
    • 

    
  • modify XTerm.ad to set saveLines
    default to 1024 (Redhat Bugzilla #127132).
    • 

    
  • add a limit-check in dotext() to prevent
    infinite loop in a corner case of UTF-8 configuration.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #191 - 2004/6/6 -
  XFree86 4.4.99.7


  
    
    
  • correct options parsing for -into option so it
    can be combined with -e (Redhat Bugzilla #124518,
    report/patch by James Armstrong).
    • 

    
  • fix ifdef's for OPT_COLOR_RES2 so that the
    fake resource table introduced in patch
    #188 is not compiled if it is empty. This happened to work
    with gcc (report by Joel Konkle-Parker).
    • 

    
  • reorganize ptydata.c to use one input buffer shared between
    the VTxxx and tek4014 emulators. In the new scheme, UTF-8
    decoding is performed on characters as they are needed by the
    state machine rather than on buffers as they are read.
    • 

    
  • work around change in quoting of PROJECTROOT symbol when
    using configure script, from changes made in patch #187 for CF_IMAKE_CFLAGS (Gentoo
    Bugzilla #50982).
    • 
  


  
Patch #190 - 2004/5/25 -
  XFree86 4.4.99.6


  
    
    
  • correct state for values in the range 128-159 after
    translating from UTF-8: this should be ignored unless the user
    overrides it with the allowC1Printable resource
    (reported by Simon Strandgaard).
    • 

    
  • add configure-script check for nl_langinfo(CODESET), use
    this to replace check of environment variables for UTF-8.
    • 

    
  • change Makefile.in rules for 256colres.h and 88colres.h so
    they are only made if they do not exist. The maintainer-clean
    rule will remove these files; they require perl to be
    made.
    • 

    
  • remove check in configure script --enable-toolbar that
    suppressed this option when building with Xaw7.
    • 

    
  • apply fixes to Tektronix widget used for VT100 widget to
    make toolbar work with Xaw7 (XFree86 4.x).
    • 
  


  
Patch #189 - 2004/5/16 -
  XFree86 4.4.99.6


  
    
    
  • do not call xim_real_init() if openIm resource
    is false (Debian #249025).
    • 

    
  • minor improvements to built-in line-drawing.
    • 

    
  • fix a few portability issues with dynamic abbreviation
    support, i.e., did not compile on Tru64.
    • 

    
  • modify constraints in form used to layout toolbar, to work
    with newer Xaw in XFree86 4.x.
    • 
  


  
Patch #188 - 2004/5/12 -
  XFree86 4.4.99.6


  
    
    
  • correct table entry for DEL in the ground state, which
    marked it as a printable character from patch #171 (report by D Hugh Redelmeier).
    • 

    
  • improve fix in patch #186 for
    failure in xim_real_init() by adding a sleep.
    • 

    
  • fix a typo in os2main.c (XFree86 Bugzilla #1358,
    report/patch by Frank Giessler).
    • 

    
  • make escape sequence reporting dynamic colors consistent
    with the logic that sets it; choosing the opposite color when
    reverse video is set (XFree86 Bugzilla #1361, reported by Bradd
    W Szonye).
    • 

    
  • modify initialization of 256- and 88-colors so that colors
    beyond 16 are normally not X resources. This works around a
    hard-coded limit in Xt which breaks xterm when 256-colors and
    luit are both configured (report by Noah Friedman).
    • 

    
  • remove ncv from xterm-256color
    terminfo entry since it is no longer needed (report by Eli
    Zaretskii).
    • 

    
  • add "erase2" and "eol2" keywords to ttyModes
    resource, for recent/current FreeBSD.
    • 

    
  • improve ifdef's for utempter library to omit direct calls
    to setutent() or getutent() (adapted
    from patch by Christian Biere).
    • 

    
  • add dynamic abbreviation support like Emacs (patch by
    Tomasz Cholewo). This is ifdef'd with OPT_DABBREV,
    and enabled via the configure script
    --enable-dabbrev option.
    • 

    
  • fix problem responding to session management events, e.g.,
    which would make logging out very slow (patch by Eddy De Greef,
    Debian #233883).
    • 

    
  • work around a newer bug in toolbar with XFree86 by forcing
    menus to be fully initialized at startup. In older versions of
    XFree86 and X11R6, it was possible to delay initialization of
    the menu contents until it was popped up. (The longstanding bug
    with XFree86 4.x layout for toolbar still exists, though).
    • 

    
  • modify xtermAddInput to work around core dump
    on IRIX64 when initializing scrollbar translations if toolbar
    is compiled-in.
    • 

    
  • fix some minor conflicts in the 2-character entry names in
    the termcap file.
    • 
  


  
Patch #187 - 2004/4/27 -
  XFree86 4.4.99.4


  
    
    
  • change xterm version string to use
    __vendorversion__ where that is available, and
    "XTerm" otherwise.
    • 

    
  • improve description of utf8 resource in
    manpage (Debian #179407).
    • 

    
  • modify configure macros CF_IMAKE_CFLAGS and CF_ADD_CFLAGS
    to handle -D options that define string values,
    e.g., for XVENDORNAME.
    • 

    
  • modify configure macro CF_IMAKE_CFLAGS to allow (if
    $PATH is set accordingly) to use the
    xmkmf script within an X build tree.
    • 

    
  • add missing #undef OPT_SESSION_MGT to
    xtermcfg.hin to make the configure script's
    --disable-session-mgt option work.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #186 - 2004/4/18 -
  XFree86 4.4.99.4


  
    
    
  • change reset on DECSCL to a soft-reset
    (appears some DEC manuals have errors).
    • 

    
  • add a section to ctlseqs.ms elaborating on normal/alternate
    screens.
    • 

    
  • modify initialization of Acolors[] so that any
    XtDefaultForeground or XtDefaultBackground values are
    translated as in the Tcolors[], to use the window's
    foreground/background colors. This affects the
    colorBD and similar resources which normally have
    no explicit color assigned.
    • 

    
  • modify initialization of Tektronix window so that control
    sequences setting its color before the window is popped up will
    apply to its initial colors.
    • 

    
  • add control sequence to set Tektronix window's
    text-cursor.
    • 

    
  • modify initialization of terminal colors, e.g., mouse
    pointer and text cursor, to treat
    XtDefaultForeground and
    XtDefaultBackground values as the actual
    foreground and background colors of the terminal rather than
    white and black (Debian #241717).
    • 

    
  • remove an incorrect comparison against
    PTYCHARLEN in parsing the -S option
    (report by Michael B Taylor).
    • 

    
  • minor restructuring of terminfo/termcap files, having noted
    some packager's customizations which caused the structure to be
    confused.
    • 

    
  • eliminate an isolated use of MIN/MAX in charproc.c
    • 

    
  • replace XtExtdefaultfont and
    XtExtdefaultbackground by their more familiar
    equivalents XtDefaultFont and
    XtDefaultBackground.
    • 

    
  • replace ifdef's using SCO, sco
    and SCO325 with __SCO__ (XFree86
    Bugzilla #1301, Kean Johnston). But ensure that it still builds
    on platforms where this symbol is not defined.
    • 

    
  • add scoFunctionKeys resource, to match
    manpage.
    • 

    
  • update manpage discussion of menus and related
    resources.
    • 

    
  • enable utmpx support for NetBSD 1.6C and newer (patch by
    Matthias Scheler).
    • 

    
  • add a note in the manpage discussing xterm's treatment of
    open file-descriptors (request by Dan Shearer).
    • 

    
  • modify Help() to make "xterm -h" write to
    standard output rather than standard error (patch by Bram
    Moolenaar).
    • 

    
  • check for type of failure in xim_real_init() to avoid
    looping when the problem is an unsupported input method rather
    than a failure to connect to the XIM server. Problem was
    introduced in patch #175 (XFree86
    Bugzilla #1306).
    • 

    
  • modify Imakefile to remove dependency of
    "install" target on the xterm executable to make
    installs from tree without attempting to rebuild anything
    (commit by David Dawes, report/patch from Lee Olsen).
    • 

    
  • remove call to ShowCursor from
    SetCursorBlink() since that is redundant, and can
    cause display glitches if the cursor is already blinking
    (XFree86 Bugzilla #1158, patch/report by Andreas Schwab).
    • 
  


  
Patch #185 - 2004/3/3 -
  XFree86 4.4


  
    
    
  • fix tcap-query logic for the backspace key (XFree86
    Bugzilla #1233, report/patch by Anton Kovalenko).
    • 

    
  • add test-scripts resize.pl and tcapquery.pl
    • 

    
  • add translation to ASCII of commonly-used characters that
    groff translates to Unicode, when the font in use does not
    provide the corresponding glyphs (Debian #219551).
    • 

    
  • modify RequestMaximize(), which performs maximize/restore
    via control sequences, to account for window-frame (patch by
    Jess Thrysoee).
    • 

    
  • improve pattern used in uxterm to check for
    UTF-8 locale, e.g., for HPUX (patch by H Merijn Brand).
    • 

    
  • add -fd option and resource
    faceNameDoublesize to specify double-wide fonts
    with Xft (adapted from patch by Zarick Lau).
    • 

    
  • change a couple of resource classes from "Boolean" to
    specific values: freeBoldBox,
    forceBoxChars.
    • 

    
  • add resource showMissingGlyphs to outline
    places on the screen where a font lacks the corresponding
    glyph.
    • 

    
  • add resource showBlinkAsBold to control
    whether blinking text should be shown as bold or actual
    blinking text.
    • 

    
  • improve logic in ShowCursor() to avoid repainting the
    cursor when it is already visible, e.g., in response to the
    DECTCEM escape sequence. This also addresses XFree86 Bugzilla
    #1158.
    • 

    
  • implement blinking text, using the timer for blinking
    cursor.
    • 

    
  • modify FreeType support to allow resizing the font, in the
    same ways the window can be resized if fixed fonts are used.
    The relative font sizes are derived from the fixed font
    sizes.
    • 

    
  • add menu items and corresponding actions for switching
    on/off the UTF-8 mode and Xft (TrueType) support.
    • 

    
  • add logic to handle switching UTF-8 mode on/off. It worked
    if the escape sequences were flushed, but if data was mixed in
    with the same write, some were not handled properly (report by
    Nicolas George).
    • 

    
  • modify to allow turning UTF-8 mode on/off via escape
    sequence even if -wc option was not given at
    startup (patch by Peter Berg Larsen).
    • 

    
  • amend fix for XFree86 Bugzilla #981, adjusting for
    savedlines value (report by Tim Adye).
    • 

    
  • fix a typo in computing relative font size (Jess
    Thrysoee).
    • 
  


  
Patch #184 - 2003/12/31 -
  XFree86 4.3.99.903


  
    
    
  • improve configure-script checks for FreeType and related
    libraries, using xft-config or
    freetype-config scripts when available.
    • 

    
  • fix configure-script check for SYSV definition
    by ensuring whether sys_errlist[] is declared, and
    by modifying the test program to include
    X11/Intrinsic.h to check that wchar_t
    is declared consistently (report by H Merijn Brand).
    • 
  


  
Patch #183 - 2003/12/26 -
  XFree86 4.3.99.903


  
    
    
  • correct logic for configurations that may attempt to open
    both old/new-style pseudoterminals. In this case, the old-style
    are preferred. Logic was broken in patch
    #145 (XFree86 Bugzilla #997, report/patch by Kean
    Johnston).
    • 

    
  • modify handling of eightBitInput resource in
    UTF-8 mode to translate the value into UTF-8. Otherwise an
    illegal UTF-8 code is sent to the application (report by Bram
    Moolenaar).
    • 

    
  • modify uxterm script to interpret help and
    version options so xterm does not always create a window when
    the user requests this information (Debian #223926).
    • 

    
  • add a limit check to ScrnTstWrapped() (XFree86 Bugzilla
    #981).
    • 

    
  • modify DECSCL to perform a hard reset (RIS) as per DEC
    manuals. Extended DECSCL to accept parameters for vt4XX and
    vt5xx terminals.
    • 

    
  • correct logic for ANSI conformance level escape sequences,
    which were confused with DEC conformance level escape
    sequences.
    • 

    
  • correct state for vt52 shift-in/shift-out, which was not
    reset properly after patch #171.
    • 

    
  • correct handling of graphics characters for vt52 mode,
    which did not display line-drawing characters after G1 fix from
    patch #182.
    • 

    
  • fixes for configure script to work with current Cygwin
    headers and libraries.
    • 

    
  • modify Imakefile to put the current directory
    at the beginning of the include searchpath (patch by David
    Dawes).
    • 
  


  
Patch #182 - 2003/12/2 -
  XFree86 4.3.99.901


  
    
    
  • correct logic for metaSendsEscape resource to
    allow for the meta-right key to be tested. Improve check for
    meta/alt modifiers by dropping the assumption that a keysym is
    associated with only one modifier, and by ignoring NoSymbol
    entries in the xmodmap data (XFree86 Bugzilla #924, patch by
    David Dawes).
    • 

    
  • correct wrapping logic for line-drawing characters written
    in non-UTF-8 mode of xterm build for wide-characters (XFree86
    Bugzilla #918, report/patch by Jürgen Keil).
    • 

    
  • improve manpage description of resources, in particular the
    utf8Fonts class (XFree86 Bugzilla #905).
    • 

    
  • add definitions to compile with glibc-based GNU/Hurd,
    GNU/KFreeBSD and GNU/KNetBSD (XFree86 Bugzilla #893).
    • 

    
  • compiler-warning fixes (patch by Christian Biere).
    • 

    
  • add README.i18n (Tomohiro Kubota).
    • 

    
  • correct initialization of G1 character set mapping, which
    used line-drawing set as a result of confusion between "DEC
    Supplemental Graphic" and "DEC Special Graphic" character sets
    (see patch #34 regarding DECSTR).
    • 

    
  • correct ifdef in main.c for variable utret (patch by
    Bernhard Rosenkraenzer).
    • 

    
  • document in xterm's manpage how to use XFree86 ":unscaled"
    keyword to suppress scaling of bold fonts.
    • 

    
  • when deriving bold fontname from normal fontname, use the
    normal font's average width to avoid for example selecting
    7x13bold from an 8x13 normal font (Debian #107769).
    • 
  


  
Patch #181 - 2003/10/26 -
  XFree86 4.3.99.15


  
    
    
  • implement boldMode for wide-character logic in
    drawXtermText() (report by Michael
    Schroeder).
    • 

    
  • modify UXTerm.ad resource file to include
    "XTerm-color" rather than "XTerm", in case the latter file
    contains no color resource definitions, e.g., after patch #180.
    • 

    
  • add action load-vt-fonts() and configure
    option --enable-load-vt-fonts which allows users
    to define additional sets of VT-fonts which can be loaded at
    runtime.
    • 

    
  • add logic to wide-character support which attempts to load
    fonts specified by utf8Fonts subresources at
    startup. The subresources have the same names as the fonts
    which they replace, e.g., font,
    font1, etc., so that the ISO-10646-1 fonts can be
    specified in the XTerm app-defaults file (adapted
    from patch by Tomohiro Kubota).
    • 

    
  • improve Set Font escape string handling by making the
    relative settings apply to the size of the font, as in shift
    keypad plus/minus rather than the menu index.
    • 

    
  • simplify parameter passing for the set-vt-font
    action and related code.
    • 

    
  • cleanup some include-ordering, moving some recently-added
    hardcoded stuff into xterm.h where it will not interfere with
    the configure script.
    • 

    
  • modify xtermAddInput() (see note on
    augmentation in patch #158) to use the
    complete set of default keyboard translations so that one can
    use shifted pageup, wheel mouse, etc., while the mouse pointer
    is over the scrollbar. (Debian #178812).
    • 

    
  • make save/restore mode controls apply to show/blink cursor
    states.
    • 

    
  • add escape sequence to start/stop blinking cursor, which
    allows implementing cvvis terminfo capability
    (request by Nate Bargmann).
    • 

    
  • add indp and rin to terminfo
    entry.
    • 

    
  • fix an out-of-bounds array reference in ScrnRefresh() for
    wide characters (report by Dan Harnett, patch by Todd Miller).
    This bug dates from patch #141.
    • 
  


  
Patch #180 - 2003/10/12 -
  XFree86 4.3.99.15


  
    
    
  • several fixes for rendering using Xft via option
    -fa:

      
      
        
    • translate Unicode values, i.e,. from UTF-8 output to
        xterm, for line-drawing to xterm's internal code, etc.,
        since TrueType fonts generally do not have either set of
        line-drawing glyphs. xterm can draw these directly (report
        by Abigail Brady).
      • 

        
    • pass 16-bit values rather than 8-bit values to
        xtermXftDrawString() to allow for wide-characters.
      • 

        
    • remove spurious check for colorBDMode
        resource in logic that does bold fonts.
      • 

        
    • implement underlining.
      • 
      
    
    
    • 

    
  • patches by Ilya Zakharevich:

      
      
        
    • improve drawXtermText() by making the recursive calls
        communicate through arguments, and not through
        saving/restoring global variables.
      • 

        
    • make double-width characters work with -u8
        option.
      • 

        
    • modify lookup of double-sized fonts by checking for a
        match ignoring x/y resolution if the first check
        fails.
      • 
      
    
    
    • 

    
  • make height of TrueType fonts match ascent+descent (patch
    by Keith Packard).
    • 

    
  • correct configure-script check for imake $CFLAGS, which did
    not check properly if imake was not available.
    • 

    
  • correct install rule in Makefile.in for
    uxterm, which was attempting to strip the script
    (newsgroup posting by Fernan Aguero).
    • 

    
  • correct AF/AB strings in termcap for xterm-256color and
    xterm-88color entries (report by Josh Howard).
    • 

    
  • update wcwidth.c to incorporate changes from Markus Kuhn's
    2003-05-20 (Unicode 4.0) version of that file.
    • 

    
  • modify scroll-back and
    scroll-forw actions to accept an adjustment value,
    e.g.,
      
                  scroll-back(1, page-2)

    to scroll back by 2 lines less than a page (patch by Greg
Klanderman).
    
    • 

    
  • use color resource setting from Debian package for xterm
    VT100 widget, since the choice of blues provides better
    contrast.
    • 

    
  • remove color resources from XTerm.ad, leaving
    them only in XTerm-col.ad (prompted by Debian
    package for xterm).
    • 

    
  • correct configure script option --enable-pty-handshake
    (report by Paul Gilmartin).
    • 

    
  • add visualBellDelay resource to modify the
    length of time used for visual bell, for very slow displays or
    very fast computers (reports by Ingo van Lil and Doug
    Toppin).
    • 

    
  • correct logic for initializing dynamic highlight color
    (patch by Jess Thrysoee).
    • 

    
  • add a check for non-zero size in call to
    XCopyArea() to accommodate a Solaris bug.
    • 

    
  • correct typo in example for character classes in xterm
    manpage (Debian #198910).
    • 

    
  • link xterm with bind_on_load option on Darwin to work
    around a deadlock in the dynamic loader when a signal is
    received while the dynamic loader is looking up symbols
    (patches by Rob Braun, Torrey Lyons).
    • 

    
  • modify configure script to avoid using "head -1".
    • 

    
  • update config.guess, config.sub
    • 

    
  • modify ifdef's to work around inclusion of types FcChar32
    and XftCharSpec with FreeType 2.0 (see patch #175).
    • 

    
  • modify the predictable version of the generated logfile
    name (see patch #171) to append the
    process-id rather than a random value.
    • 

    
  • resync with XFree86 CVS

      
      
        
    • Enable SCO function keys in xterm
      • 

        
    • Make Delete key send DEL by default on SCO in
        xterm
      • 
      
    
    
    • 
  


  
Patch #179 - 2003/5/21 -
  XFree86 4.3.99.5


  
    
    
  • modify ifdef's for WTMPX_FILE to allow building on cygwin
    again.
    • 

    
  • change the default of pty-handshaking configure option (and
    related default for imake) to assume this feature is
    needed.
    • 

    
  • add ifdef's so configure option for XawPlus library works
    (patch by Pavel Roskin).
    • 

    
  • add $(MAIN_DEFINES) to the variables checked
    by the configure script that may contain information set by
    imake. This allows xterm to build/run properly using the
    configure script on IRIX64.
    • 

    
  • add configure check for ".exe" suffix on cygwin.
    • 
  


  
Patch #178 - 2003/5/18 -
  XFree86 4.3.99.5


  
    
    
  • modify default for configure
    --enable-pty-handshake option to enable it for
    Solaris (report by Nelson Beebe).
    • 

    
  • modify in_put() function to call
    PreeditPosition() only when the cursor's position
    has changed. This addresses report by Stefan Baums of high CPU
    usage while xterm with chinput are running in the background
    (patch by Yong Li).
    • 

    
  • improved explanation of -ls conflict with
    -e option in xterm manpage (adapted from comments
    by Henning Makholm).
    • 

    
  • correct comment in terminfo file regarding modifier used
    for kDC (Debian #189764, report by Henning
    Makholm).
    • 

    
  • correct/extend some of the keypad description in ctlseqs.ms
    (report by Henning Makholm).
    • 

    
  • correct keypad-mapping table in input.c so
    XK_KP_Equal works (report by Henning
    Makholm).
    • 

    
  • modified to work with CJK double-width (bi-width/monospace)
    fonts. They're similar to Roman Czbora and David Starner's
    gnuunifonts in that Latin letters and numbers have all the same
    width which is exactly the half of the width of East Asian
    characters. (patch by Jungshik Shin
    <jshin@mailaps.org>).
    • 

    
  • add configure option --enable-broken-osc and
    resource brokenLinuxOSC to accommodate scripts
    which do not distinguish between running in the Linux console
    and running in X. Linux console recognizes malformed control
    strings which start with an OSC, but are
    fixed-length, with no terminator.
    • 

    
  • add configure option --enable-broken-st and
    resource brokenStringTerm to allow user to revert
    one part of the parsing table corrections from patch #171. (reports by Matthias Scheler and
    Kirill Ponomarew indicate that someone's network firmware sends
    an <escape>X).
    • 

    
  • modify configure --disable-imake to provide
    values for OSMAJORVERSION,
    OSMINORVERSION, FUNCPROTO and
    NARROWPROTO (report by Heiko Schlichting).
    • 

    
  • correct vttests/16colors.sh, which omitted the
    $SUF variable in output strings (patch by Paul
    Gilmartin).
    • 

    
  • modify shell scripts in vttests directory to
    attempt to use named signals in the trap
    statement, making this portable to OS/390 (report by Paul
    Gilmartin). Tested on SunOS 4.1.4, which implements only
    numbers.
    • 
  


  
Patch #177 - 2003/3/23 -
  XFree86 4.3.0


  
    
    
  • fix definition of USE_HANDSHAKE, must be
    numeric (reported by Jens Schleusener).
    • 
  


  
Patch #176 - 2003/3/22 -
  XFree86 4.3.0


  
    
    
  • add configure option --enable-pty-handshake to
    allow one to compile-in support for the pty handshaking logic,
    and resource ptyHandshake to enable or disable it
    (suggested by Ian Collier).
    • 

    
  • restore USE_HANDSHAKE ifdef removed in
    patch #159 to address Debian
    #39964.
    • 

    
  • move ifdef's for ttysize/winsize into xterm_io.h
    • 

    
  • simplify loop on tgetent, check if the
    successive entries in the lookup table are the same. That makes
    xterm do one less lookup if there is no "xterm" entry in the
    termcap file (report by Derek Martin).
    • 

    
  • correct manpage discussion of $TERM and
    $TERMCAP variables, which omitted the Tektronix
    emulation and a note of the final "dumb" fallback.
    • 

    
  • broaden ifdef for
    XRegisterIMInstantiateCallback() from patch #175 (XIM fix) to exclude non-XFree86
    (report by Nelson Beebe indicates this breaks for Solaris, IRIX
    and OSF/1).
    • 

    
  • correct resource-size for iconFont (this was
    added by X11R6.3).
    • 

    
  • improve configure check for XKB bell extension, to work
    around inconsistent implementation of this feature (reports by
    Nelson Beebe, Kriston Rehberg and David Ellement).
    • 

    
  • modify configure-check for tty group to be
    less strict in batch mode (report by Nelson Beebe).
    • 

    
  • modify to allow building with g++, to use its compiler
    warnings (suggested by Nelson Beebe).
    • 

    
  • modify dec2ucs[] table to reflect newer codes
    available for scanlines 1, 3, 7, 9 (report by Michael
    Schroeder).
    • 

    
  • add configure option for XawPlus library.
    • 
  


  
Patch #175 - 2003/3/9 -
  XFree86 4.3.0


  
    
    
  • fix a SIGSEGV which could occur if xterm is connecting to
    XIM server, and the XIM server is destroyed (patch by Nam
    SungHyun).
    • 

    
  • modify to use built-in line-drawing characters for Xft
    fonts (patch by Andrew Tipton).
    • 

    
  • make menu reflect the state of the tekInhibit
    resource.
    • 

    
  • make signalInhibit resource work, i.e.,
    disable the menu entries that would send signals to, or exit
    xterm. This was probably broken in X11R5 when logging was
    disabled (report by Sven Mascheck).
    • 

    
  • changed classes of colorBDMode and similar
    resources that override colors when a video attribute is set to
    ColorAttrMode, to make them distinct from
    ColorMode. This avoids an unexpected rendering of
    reverse video, for example (report by Paul Fox).
    • 

    
  • changed class of veryBoldColors to
    VeryBoldColors, since ColorMode is
    associated with boolean resources.
    • 

    
  • add option -k8 and resource
    allowC1Printable to allow users of non-VTxxx
    character sets such as KOI-8 to treat the C1 control area
    (character codes 128-159) as printable rather than control
    characters.
    • 

    
  • add a null-pointer check for return-value of
    ptsname() in HPUX-specific code (report by David
    Ellement).
    • 

    
  • revise the ifdef's used for XKB bell support.
    The code was using a nonstandard call
    XkbStdBell(). Changed to use
    XkbBell() (based on patch by
    <derek@signalmarketing.com>).
    • 

    
  • add a null-pointer check in xtermLoadFont() in
    case there is no wide-bold font (Nam SungHyun).
    • 

    
  • change Makefile.in to use autoconf's
    bindir, libdir and
    mandir variables (report by Nam SungHyun).
    • 

    
  • add le to termcap xterm-basic
    entry. Though missing from older termcaps for xterm, some
    applications check for it (report by Matthias Buelow).
    • 

    
  • modify uxterm script to strip modifiers such
    as "@euro" from the locale setting before adding ".UTF-8"
    (Debian #179929).
    • 

    
  • modify the remaining places where tek4014 emulation uses
    XDefineCursor(), to make it work as originally
    implemented, e.g., when switching back to alpha mode. Added
    test-screen in vttest to test this feature properly.
    • 
  


  
Patch #174 - 2003/2/25 -
  XFree86 4.2.99.903


  
    
    
  • work-around for XFree86 bug which made
    XDefineCursor() on a shell-window no longer work.
    The tek4014 emulation used this. Use the next lower window
    (report by Karl Rudolf Bauchspiess).
    • 

    
  • add a resource setting allowWindowOps to
    control whether the extended window operations should be
    allowed, e.g., resize, iconify, report window attributes. This
    is to accommodate people who are not capable of using a pager
    to view log-files.
    • 
  


  
Patch #173 - 2003/2/6 -
  XFree86 4.2.99.902


  
    
    
  • reset mouse mode to normal on a full reset. This does not
    apply to mouse hilite tracking mode, of course (see
    ctlseqs.ms).
    • 

    
  • add a time-delay at the point where mouse hilite tracking
    mode choses to not handle X events, to avoid runaway CPU usage
    (report by D Hugh Redelmeier).
    • 

    
  • check for illegal character in DECUDK string, quit if
    detected.
    • 
  


  
Patch #172 - 2002/12/27 -
  XFree86 4.2.99.3


  
    
    
  • fixes to make repainting of 256-color example work properly
    (reports by Abigail Brady and Scott A Crosby).

      
      
        
    • set flag in AllocateAnsiColor() to ensure
        the color is allocated once only.
      • 

        
    • fix check in ScrnRefresh, which was
        comparing background colors only if the ANSI foreground
        colors also were set.
      • 
      
    
    
    • 

    
  • merge Error() calls and some
    exit() calls into SysError(), and
    change that to add the brief explanation for each error code
    which is provided in the manpage. Change a few
    SysError(), calls to avoid using code 1, to avoid
    confusion with exit status from places that do not use
    SysError().
    • 

    
  • simplify logic used to open a debug logfile as the standard
    error.
    • 

    
  • modify the -e option so that if it fails,
    xterm will check if only one argument follows, e.g., it was
    quoted, and then retry using sh -c.
    • 

    
  • modify parsing of DECUDK string parameter to allow a comma
    between pairs of hexadecimal digits (Ray Neuman
    <raymond@one.com.au> reports that "real" terminals accept
    this; perhaps they simply ignore unexpected characters).
    • 

    
  • fix a few problems with the $TERMCAP string
    generated by resize:

      
      
        
    • for Bourne shell, add an export command.
        This was missing as far back as X11R5.
      • 

        
    • escape exclamation marks, used in xterm's reset
        string.
      • 

        
    • translate literal \177\ to "^?".
      • 
      
    
    
    • 

    
  • improve configure check for tgetent() to work
    when $TERMCAP has been set to a specific
    entry.
    • 

    
  • modify minstall.sh to use "%" rather than "@",
    to avoid problems with AFS (report by Zdenek Sekera).
    • 

    
  • list fatal error codes from error.h in the
    manpage, remove unused codes in error.h.
    • 

    
  • use more explicit wording for manpage list of color
    resources, since at least one user confused the generic names
    such as "black" with the names in rgb.txt (the latter are now
    used).
    • 

    
  • minor fix to description of 1003 mouse mode in ctlseqs.ms
    (Larry Riedel).
    • 
  


  
Patch #171 - 2002/12/12 -
  XFree86 4.2.99.3


  
    
    
  • modify parser tables to improve detection of malformed
    control sequences, making xterm behave more like a real DEC
    terminal (patch by Paul Williams).
    • 

    
  • update comment in input.c to document
    Meta as a modifier for escape sequences (patch by
    D Roland Walker).
    • 

    
  • add ifdef'd code for logging option which adds the hostname
    and a timestamp to the generated logfile name. The ifdef's are
    setup with the configure script (patch by Nelson Beebe).
    • 

    
  • remove xevents() call from the end of
    BlinkCursor(), to fix an occasional problem which
    caused xterm to pause until a key was pressed. The reason for
    this was that there was no check to ensure that there really
    were events for xevents() to process. (patch by
    Semen A Ustimenko <semenu@FreeBSD.org>).
    • 

    
  • remove unused mode-params from open() calls
    that do not create a file.
    • 

    
  • modify configure script to put new items first on
    $CPPFLAGS and $CFLAGS to avoid
    conflict with environment's -I and -D
    options.
    • 

    
  • update config.guess, config.sub
    • 

    
  • resync with XFree86 CVS

      
      
        
    • fix va_args glitches for xterm/libfontconfig: 0 ==
        (void*)0 isn't true for all platforms (Egbert Eich).
      • 

        
    • initialise ProgramName in xterm's main before
        referencing it (XFree86 #5473, Peter Valchev).
      • 

        
    • some cleanup of Imakefile ifdef's (Marc La
        France).
      • 
      
    
    
    • 
  


  
Patch #170 - 2002/10/13 -
  XFree86 4.2.1


  
    
    
  • correct an off-by-one allocating data for sorted help
    message.
    • 

    
  • modify configure script to check for Xpm library, on which
    XFree86 Xaw library depends.
    • 

    
  • update config.guess, config.sub
    • 
  


  
Patch #169 - 2002/10/5 -
  XFree86 4.2.1


  
    
    
  • modify wording of some options in help message to make them
    use -/+ consistently with respect to "on/off" or
    "off/on".
    • 

    
  • sort options list which is displayed in help- and
    syntax-messages at runtime to simplify maintenance.
    • 

    
  • remove support for Amoeba and Minix (Juliusz Chroboczek
    noted it was removed from XFree86 server; there have been no
    users since 1996).
    • 

    
  • add configure script option
    --disable-session-mgt to control whether the
    session management code should be compiled-in (request by H
    Merijn Brand).
    • 

    
  • ifdef'd the session-management changes with
    OPT_SESSION_MGT, to accommodate X11R5 which
    predates the related definitions.
    • 

    
  • fix decode_keyvalue(), which did not properly
    parse multiple settings as needed for the ttyModes
    resource, since it did not skip over the parsed data.
    • 

    
  • fix an option-parsing conflict between -class
    and -cjk_width (Nam SungHyun)
    • 

    
  • add a missing null in XtVaSetValues() call
    used in Cleanup() (Nam SungHyun)
    • 
  


  
Patch #168 - 2002/9/29 -
  XFree86 4.2.1


  
    
    
  • improve data reported for control sequence that requests
    window position by taking into account the window decorations,
    e.g., border and title (patch by Jess Thrysoee
    <jess@thrysoee.dk>).
    • 

    
  • add -cjk_width and corresponding resource
    cjkWidth (patch by Jungshik Shin
    <jshin@mailaps.org>).
    • 

    
  • add -into option, for embedding xterm in a
    Tcl/Tk application (patch by George Peter Staplin
    <georgeps@xmission.com>).
    • 

    
  • add simple session management (XSM) client capabilities to
    xterm. So a session manager such as, e.g., xsm, should be able
    to respawn or kill xterms without the help of an SM proxy (like
    smproxy), which is a hack and almost always buggy (patch by
    David Madore).
    • 

    
  • fix conflict between ifdef's for
    OPT_DEC_LOCATOR and OPT_READLINE in
    button.c (reported by Ilya Zakharevich).
    • 

    
  • fix for inconsistent use of struct utmp versus
    struct utmpx introduced in patch #167 (patches by Paul Gilmartin, Marc La
    France).
    • 

    
  • modify logic for metaSendsEscape to allow it
    to work in a setup where the Meta-key is not recognized as a
    modifier by the key-translations logic (discussion of
    eightBitInput with H.J.Lu). Note however that Vincent Lefevre
    reported this in January).
    • 

    
  • use null pointer values consistently, rather than literal
    "0", for ending variable-length argument lists, e.g., for
    execlp() (based on patch by Matthieu Herrb).
    • 

    
  • correct logic of ChangeAnsiColorRequest(),
    which would do a screen repaint after replying to a request for
    information.
    • 

    
  • improve scripts in vttests to work with systems whose
    shells support echo -n and have, as does Debian,
    an unrelated print utility.
    • 

    
  • add vttests/acolors.sh to demonstrate OSC 4, which queries
    or sets ANSI colors.
    • 

    
  • fixes for ctlseqs.ms (Pavel Roskin, Ilya Zakharevich).
    • 

    
  • typos in xterm manpage (Jens Schweikhardt)
    • 

    
  • remove a redundant GCC_UNUSED from InitPopup() (Nam
    SungHyun)
    • 
  


  
Patch #167 - 2002/8/24 -
  XFree86 4.2.0


  
    
    
  • correct ifdef's for USE_TERMCAP to match
    cygwin configuration.
    • 

    
  • fix several places in ctlseqs.ms which had no boxes around
    the literal text (report by Ilya Zakharevich).
    • 

    
  • extend mouse support for readline, ifdef'd with
    OPT_READLINE (integrated patch from Ilya Zakharevich).
    • 

    
  • modify terminfo description to match default for
    modifyCursorKeys resource.
    • 

    
  • add modifyCursorKeys resource to control how
    the shift- and similar modifiers are used to make a cursor
    escape sequence. The default makes a modified escape sequence
    always start with CSI and puts the modifier as the second
    parameter, to avoid confusing applications that would interpret
    the first parameter as a repeat count. The original behavior
    can be obtained by setting the resource to 0 (newsgroup
    discussion with Stephen J Turnbull, Jeffrey Altman).
    • 

    
  • correct missing initializations for
    appdefaultCursor and appdefaultKeypad
    resources.
    • 

    
  • add configure option --enable-luit and ifdef'd
    the luit-related code with OPT_LUIT_PROG.
    • 

    
  • modify xterm to invoke luit (integrated patch by Tomohiro
    Kubota)
    • 

    
  • update wcwidth.c to match Markus Kuhn's 2002-05-18
    version.
    • 

    
  • correct limit-checking in ComputeSelect() to
    handle selections that extend off the visible area; rather than
    modify the parameters to TrackText(), use
    ScrollSelection() to update the highlighting
    limits. (reported by Yegappan Lakshmanan and Nelson Beebe,
    patch by Alexander V Lukyanov).
    • 

    
  • correct manpage description of tiXtraScroll
    resource (reported by Tony Finch).
    • 

    
  • changes from OpenBSD:

      
      
        
    • Make xterm setgid utmp to be able to update utmp even
        with root privileges revoked.
      • 

        
    • If not updating utmp, revoke group privileges totally
        too.
      • 
      
    
    
    • 

    
  • changes from NetBSD:

      
      
        
    • Check that the return value from ttyslot() is greater
        than 0 before writing the utmp file. Fixes w's "w: Stale
        utmp entry: <user> <tty> <pty>"
        errors.
      • 

        
    • Use openpty() to deal with new pty naming scheme.
      • 
      
    
    
    • 

    
  • add print-redir action and menu entry to allow
    user to switch terminal in/out of printer controller mode. It
    appears from the manual that a real vt220 would not switch back
    to normal mode, so another mechanism is used (addresses Debian
    #37517).
    • 

    
  • check if printerCommand resource string is
    empty, use this to allow user to disable printer function.
    • 

    
  • trim trailing blanks from resource strings.
    • 

    
  • check return value from ptsname(), which may
    return null for example if someone has changed the permissions
    of /dev/pts to zero (Debian #121899).
    • 

    
  • modify OS/2 version to use __UNIXOS2__
    definition rather than __EMX__, related cleanup
    (patch by Holger Veit).
    • 

    
  • used modified indent 2.0 (patch 20020428) to
    reformat most of the C source files, to simplify
    maintenance.
    • 

    
  • fix a couple of places where there were leading tabs on
    symbol-definition lines in Imakefile (Marc La France from
    report by Tony Finch)
    • 

    
  • add imake variable (TraceXTerm) to allow building debug
    version (Egbert Eich).
    • 
  


  
Patch #166 - 2002/3/25 -
  XFree86 4.2.0


  
    
    
  • correct a bug in selection: double clicking on a word which
    was partly scrolled off the screen may select that text (report
    by Vincent Lefevre <vincent@vinc17.org>).
    • 

    
  • implement veryBoldColors resource to control
    whether the corresponding video attribute such as
    bold is displayed when using
    colorBDMode, etc. (request by Josh Howard
    <jrh@vicor-nb.com>).
    • 

    
  • define escape sequences for function keys F21-F35 (patch by
    Stephen P Wall).
    • 

    
  • change the colors for the 256-color model, making them less
    skewed toward black (patch by Stephen P Wall).
    • 

    
  • add vt100Graphics resource (see patch #115, based on discussion with Glenn
    Maynard).
    • 

    
  • ifdef'd Xaw/Xaw3d/neXtaw includes separately to avoid
    potential incompatibilities between these flavors of Athena
    widgets.
    • 

    
  • add configure check for XFree86 4.x Xaw library, whose
    geometry management is broken, to avoid trying to use it for
    toolbar configuration.
    • 

    
  • updates to configure script from vile and lynx to allow
    configure.in to be compiled with autoconf 2.5x
    • 

    
  • add a check for null pointer return by
    ptsname() (newsgroup posting from Mike Silva
    <mikesilva@lucent.com>).
    • 

    
  • fill in a few details needed to allow UTF-8 mode to switch
    on/off after startup. This requires that wideChars
    resource be set. (based on comments in 4 Aug 2001 by Alexey
    Marinichev <lyosha@lyosha.2y.net>).
    • 

    
  • remove duplicate install rules that make directories, e.g.,
    so installing manpage will not create app-defaults
    directory.
    • 

    
  • add comment in in do_osc(), reserving cases 30
    and 31 for for Konsole (request by Stephan Binner
    <Stephan.Binner@gmx.de>).
    • 

    
  • fixes for ctlseqs.ms and xterm.man (patch by Werner Lemberg
    <wl@gnu.org>).
    • 

    
  • add check for monochrome display, disabling colorMode in
    that case (fixes Debian #134130).
    • 

    
  • resync with XFree86 CVS

      
      
        
    • Fix some xterm build warnings on *BSD (patch by David
        Dawes).
      • 

        
    • Only use SA_RESTART in xterm when it's available (patch
        by Frank Liu).
      • 

        
    • Fix incorrect code in signal handlers in most of the
        clients, xterm and xdm not done yet (patch by Matthieu
        Herrb).
      • 
      
    
    
    • 
  


  
Patch #165 - 2002/1/5 -
  XFree86 4.1.0


  
    
    
  • modify uxterm script to strip encoding part
    from environment variable before adding ".UTF-8" (based on
    Debian #125947, but using a more portable solution).
    • 

    
  • add an assignment statement in VTInitialize() to make
    awaitInput resource work.
    • 

    
  • use new macros init_Bres(), etc., in VTInitialize() to add
    trace of the initialization of resources.
    • 

    
  • modify checks for $LC_ALL, related environment variables to
    ensure the resulting strings are nonempty (report by Markus
    Kuhn).
    • 

    
  • add an ifdef in charproc.c for num_ptrs variable in case
    all configure options are disabled.
    • 

    
  • modify definition of getXtermBackground() to avoid negative
    array index warning on Tru64 (report by Jeremie Petit).
    • 

    
  • improve fix from patch #165 (still Debian #117184, report
    by Matt Zimmerman <mdz@debian.org>)
    • 

    
  • correct install rule for uxterm in Makefile.in, to handle
    the case where building in a different directory than xterm's
    source (patch by Paul Gilmartin).
    • 

    
  • documented ANSI.SYS-style cursor save/restore escape
    sequences in ctlseqs.ms, which are in xterm since X11R5.
    • 

    
  • correct two entries in the default charClass table, which
    did not follow the manpage comment about the character number
    corresponding to the class (patch by Marc Bevand
    <bevand_m@epita.fr>).
    • 

    
  • fix a couple of typos in comments in the app-defaults files
    (David Krause <xfree86@davidkrause.com>).
    • 

    
  • resync with XFree86 CVS

      
      
        
    • update language of copyrights in some files to reflect
        the fact that they were reassigned from X Consortium to The
        Open Group in 1998. Note that this xterm source is derived
        from the 1996 version from X Consortium, does not
        incorporate changes made by X Consortium or The Open Group
        after that date, hence we do not add The Open Group's 1998
        copyright date to related files.
      • 

        
    • save/restore errno in signal catcher
        (patch by Matthieu Herrb).
      • 

        
    • modify UXTerm.ad's font5 resource so that xterm can
        display double width characters using a font distributed
        with XFree86 (Tomohiro Kubota).
      • 
      
    
    
    • 
  


  
Patch #164 - 2001/11/13 -
  XFree86 4.1.0


  
    
    
  • correct a case where ptyInitialErase and
    backarrowKeyIsErase resources combine to set
    DECBKM mode, but a reset command
    would not reset xterm to that state, making the erase character
    revert to ^H (Debian #117184)
    • 
  


  
Patch #163 - 2001/11/04 -
  XFree86 4.1.0


  
    
    
  • correct ifdef's for __QNX__ and
    USE_SYSV_PGRP in main.c call to
    tcsetpgrp, which broke bash behavior around
    patch #140 (report/patch by Frank Liu
    <fliu@mail.vipstage.com>).
    • 

    
  • modify trace.c to fix missing definition of GCC_UNUSED for
    compilers other than gcc when configured for trace code
    (report/patch by Paul Gilmartin).
    • 

    
  • change format in TraceOptions() to use long rather than
    int, since the latter could lose precision on 64-bit machines
    (report/patch by Nelson Beebe).
    • 

    
  • modify xterm manual page and minstall.sh to allow imake
    rules to define location of app-defaults directory (Debian
    #87611).
    • 

    
  • review/update list of conflicting preprocesor symbols to
    remove from $CPPFLAGS at the end of the configure script. In
    particular, this allows one to configure xterm without the
    utempter library on Redhat 7.1 (report/patch by Adam
    Sulmicki).
    • 
  


  
Patch #162 - 2001/10/23 -
  XFree86 4.1.0


  
    
    
  • correct logic that processes -class option, so
    that a following -e option is handled (Debian
    #116297).
    • 

    
  • improve options-decoding to allow -version and
    -help options to be combined (Debian
    #110226).
    • 

    
  • add a 10 millisecond delay in event loop when processing
    -hold option, to avoid using too much CPU time
    (Debian #116213).
    • 

    
  • prefix final program execution in uxterm with
    "exec" to avoid a useless shell hanging around (Christian
    Weisgerber).
    • 
  


  
Patch #161 - 2001/10/10 -
  XFree86 4.1.0


  
    
    
  • modify logic that resets keypad application mode to avoid
    doing this if there is no modifier associated with the Num_Lock
    keysym (report by John E Davis <davis@space.mit.edu> and
    Alan W Irwin <irwin@beluga.phys.uvic.ca>).
    • 

    
  • add built-in translation for Control/KP_Separator to
    KP_Subtract, to accommodate users who wish to use xmodmap to
    reassign the top row of the numeric keypad.
    • 

    
  • correct Imakefile install-rule for uxname
    script (reported by Nam SungHyun <namsh@lge.com>).
    • 

    
  • resync with XFree86 CVS – correct typo in
    <ncurses/term.h> ifdef.
    • 
  


  
Patch #160 - 2001/10/7 -
  XFree86 4.1.0


  
    
    
  • modify logic in main.c (see patch
    #145) to avoid generating the same identifier, for example,
    for /dev/tty1 and /dev/pts/1, which is used to denote an entry
    in the utmp file (Debian bug report #84676), A similar fix was
    also sent by Jerome Borsboom <borsboom@westbrabant.net>
    in May, but I overlooked it when reviewing bug reports.
    • 

    
  • add configure check for <ncurses/term.h>
    to get rid of hardcoded __CYGWIN__ ifdef in
    resize.c

      
    NOTE: The CYGWIN port should not be linking
      resize with ncurses. It appears that the only
      reason it is, is because both the ncurses and termcap ports
      on that platform are badly misconfigured (essential pieces
      have been removed, etc). Checking for
      <ncurses/term.h> does not hurt anything,
      since there are some correct installations that are set up
      that way.
    
    
    • 

    
  • add a sample uxterm script, which uses the
    UXTerm application defaults for UTF-8
    environments.
    • 

    
  • undo change to xterm application defaults, since this
    introduced an unnecessary incompatibility. The intended
    functionality was already addressed by the UXTerm app-defaults file.
    • 

    
  • resync with XFree86 CVS

      
      
        
    • Modified xterm app default to use LFD fontnames instead
        of old type (Michael Schroeder).
      • 

        
    • Fix xterm when XIM is disabled - caused a segfault
        (Tomohiro Kubota).
      • 
      
    
    
    • 
  


  
Patch #159 - 2001/9/19 -
  XFree86 4.1.0


  
    
    
  • remove an ifdef for USE_HANDSHAKE added in
    patch #158 from the second TIOCSSIZE ioctl call in
    the initialization code. Paul Gilmartin reports that for
    Solaris 2.6 (sparc), stty does not show that xterm sets rows
    and columns unless the second ioctl is executed.
    • 

    
  • correct treatment of empty parameter list for some OSC
    strings (report by Sami Farin <sfarin@ratol.fi>).
    • 
  


  
Patch #158 - 2001/9/8 -
  XFree86 4.1.0


  
    
    
  • augment key translations for scrollbar widget to ensure
    that keystrokes intended for the text area are not lost if the
    mouse pointer happens to fall on the scrollbar. This can
    happen, for instance, if the user's app-defaults
    or .Xdefaults file contains a translations
    resource, though it may also happen through unrelated resource
    settings: probably a bug in libXt (reported by Paul Fox
    <pgf@foxharp.boston.ma.us> and Dmitry Yu. Bolkhovityanov
    <D.Yu.Bolkhovityanov@inp.nsk.su>).
    • 

    
  • widen ifdef's in xterm.h to define
    __EXTENSIONS__ on Solaris, for compilers other
    than gcc. This was added along _POSIX_C_SOURCE
    with in patch #151, but is not
    sufficient since Sun's compiler does not define
    __STDC__ by default (report by Matthias Scheler
    <tron@zhadum.de>).
    • 

    
  • modify xterm to obtain the closest matching color if an
    exact color is not available, e.g., on 8-bit displays (patch by
    Stephen P Wall)
    • 

    
  • implement "OverTheSpot" preedit type of XIM input (patch by
    Tomohiro Kubota):

      
      
        
    • This preedit type is a reasonable compromise between
        simpleness of implementation and usefulness. "Root" preedit
        type is easy to implement but not useful; "OnTheSpot"
        preedit type is the best in the point of view of user
        interface but very complex. And more, "OverTheSpot" is the
        preedit type which the most XIM servers support. Thus, to
        achieve reasonable usability, support of "OverTheSpot"
        preedit type is needed.
      • 

        
    • In "OverTheSpot" preedit type, the preedit
        (preconversion) string is displayed at the position of the
        cursor. On the other hand, it is XIM server's
        responsibility to display the preedit string. Thus, it is
        needed for XIM client (here XTerm) to inform the XIM server
        of the cursor position. And more, to achieve good visual
        proportion, preedit string must be written using proper
        font. Thus, it is XIM client's responsibility to inform the
        XIM server of the proper font. The font must be supplied by
        "fontset". Fontset is a set of fonts with charsets which
        are specified by the current locale. Since XTerm uses
        ISO10646 fonts regardless of the current locale, the fonts
        for XIM must be prepared separately. It is difficult to
        prepare fonts which are similar to XTerm font. Thus, my
        patch uses a simple way - the default font is "*" which
        matches every fonts and X library will automatically choose
        fonts with proper charsets. I added "-fx" command option
        and "ximFont" resource to override this default font
        setting.
      • 

        
    • changed the definition of "OverTheSpot" preedit type
        from XIMPreeditPosition|XIMStatusArea to
        XIMPreeditPosition|XIMStatusNothing. This matches the
        behavior of other programs such as Rxvt, Kterm, Gedit.
      • 

        
    • A tiny XIM bugfix is also included. By calling
        XSetLocaleModifiers() with parameter of "", it can consier
        XMODIFIERS environmental variable which is a standard way
        for users to specify XIM server to be used.
      • 
      
    
    
    • 

    
  • adjust configure script to accommodate repackaging of
    keysym2ucs.c as include-file for xutf8.c (patch by Tomohiro
    Kubota).
    • 

    
  • add the UXTerm app-defaults file to makefile
    install rules (request by Juliusz Chroboczek).
    • 

    
  • correct logic in get_termcap(), which returned
    false if the tgetent() call indicated that xterm
    was linked with terminfo. Although the $TERMCAP
    variable cannot be adjusted in this case, xterm still needs
    information from this call to extract data to initialize the
    erase-mode when the ptyInitialErase resource is
    false.
    • 

    
  • modify ScrollbarReverseVideo() function to
    cache the original border color, so it can restore that when an
    application flashes the screen (Bugzilla #38872).
    • 

    
  • resync with XFree86 CVS

      
      
        
    • remove ifdef's for X_NOT_STDC_ENV (patch by David
        Dawes).
      • 

        
    • add Cygwin to special errno handling case in ptydata.c
        (Alan Hourihane)
      • 

        
    • set screen size earlier in initialization, to address a
        race with window manager resizing its clients (Keith
        Packard).
      •

Patch #157 - 2001/6/18 -
  XFree86 4.1.0


  
    
    
  • clean up button.c and input.c (patch by Juliusz
    Chroboczek). The basic idea is to use a single set of APIs in
    the XTerm core, and put a set of workarounds in a separate
    file. As you will notice, this drastically simplifies parts of
    the code; in particular, the only remaining ifdefs related to
    the differences between Xutf8 and legacy systems are related to
    the selection provider logic. This defines two new files,
    xutf8.h and xutf8.c, provide some half-hearted but fully
    portable emulation for the three Xutf8* functions that XTerm
    uses. Putting these in a separate file will allow people to
    experiment with more complex versions without making the core
    of XTerm more difficult to maintain. The functionality of the
    emulation is as follows.

      
      
        
    • Xutf8TextListToTextProperty fully handles XStringstyle
        and XUTF8StringStyle. It will only generate STRING for
        XStdICCTextStyle, and wil only generate Latin-1 in
        XCompoundTextStyle (but label it as COMPOUND_TEXT, as the
        spec requires). (I have hesitated to make this function
        fail for XStdICCTextStyle and XCompoundTextStyle; this
        might be a smart thing to do, in the hope that the
        selection requestor will try UTF8_STRING afterwards;
        opinions?)
      • 

        
    • Xutf8TextPropertyToTextList fully handles STRING and
        UTF8_STRING. It systematically fails for
        COMPOUND_TEXT.
      • 

        
    • Xutf8LookupString will properly handle single-keystroke
        input for the keysyms covered by Markus' keysym2ucs
        function. It will not handle either compose key input or
        external input methods.
      • 
      
    
    
    • 

    
  • add an ifdef for SunXK_F36, used in
    xtermcapKeycode() (patch by Mark Waggoner
    <waggoner@ichips.intel.com>).
    • 

    
  • modify check for login name to try getlogin()
    and $LOGNAME, $USER environment variables to detect if the user
    has logged in under an alias, i.e., an account with the same
    user id but a different name (Debian bug report #70084).
    • 

    
  • add resource tiXtraScroll, which can be used
    to preserve the screen contents in the scrollback rather than
    erasing it when starting a fullscreen application such as
    vi (patch by Ken Martin
    <fletcher@catsreach.org>).
    • 

    
  • two patches by Denis Zaitsev <zzz@cd-club.ru>:

      
      
        
    • added forceBoxChars resource to control
        the "line-drawing characters" option.
      • 

        
    • added freeBoldBox resource, which, when
        set true, suppresses check in
        same_font_size(), so xterm does not attempt to
        ensure that the bold font is the same size as the normal
        font.
      • 
      
    
    
    • 

    
  • change the color class for ANSI colors and similar ones
    such as bold-color, etc., to follow the convention that the
    classname is the instance name with a leading capital (e.g.,
    color0 and Color0 rather than
    color0 and Foreground). There was
    little use for Foreground as a class other than to create
    occasional confusion and bug reports, most recently by Nelson
    Beebe who reports that it disables colors in xterm but not on
    Linux, which is probably due to a difference in resource
    evaluation order. A configure script option
    (--disable-color-class) is provided for anyone who did use the
    older behavior.
    • 

    
  • fix a signal-handling bug. When running xterm with
    ksh or similar shell such as bash 2.05, xterm will
    hang and not respond to keystrokes after the user types
    suspend. Additionally the popup menus do not
    respond, so it is not possible to send SIGCONT to the shell.
    What is happening is that the shell is sending itself SIGSTOP,
    and it is being stopped. Per specification it also means that
    the operating system is sending SIGCHLD to parent to the bash
    (XTERM). Now the issue is that xterm assumes it cannot happen
    and it expects to receive SIGCHLD only upon
    termination of its children. This causes a deadlock
    with xterm waiting for the child to die, and the child waiting
    for SIGCONT. (report/patch by Adam Sulmicki), analysis/testing
    by Sven Mascheck
    <sven.mascheck@student.uni-ulm.de>).
    • 

    
  • correct some inconsistent checks for
    XtReleaseGC() calls in
    xtermLoadFont() (patch by Nam SungHyun
    <namsh@lge.com>).
    • 

    
  • updated wcwidth.c and keysym2ucs.c to versions dated
    2001/1/12 and 2001/4/18, respectively from
    http://www.cl.cam.ac.uk/~mgk25/ucs/
    • 

    
  • correction to change from patch
    #90, which was intended to reset the saved cursor position
    for normal/alternate screens on a soft reset, but actually
    wiped out all of the saved cursor information. Just reset the
    saved position for the current screen (report by Michael
    Schroeder).
    • 

    
  • modify ShowCursor() and HideCursor() so that if the cursor
    points to the second part of a wide character, make the
    show/hide operate on the first position of the wide character
    (patch by Sven Verdoolaege).
    • 

    
  • scrolling in the alternate screen just before switching
    back to the main screen can cause extra blank lines to be
    inserted into the scrollback buffer (patch by Paul Vojta
    <vojta@math.berkeley.edu>).
    • 

    
  • resync with XFree86 4.1.0:

      
      
        
    • Use TermcapLibrary as -lncurses instead of -ltermcap,
        fixes problem building xterm/resize on Cygwin/XFree86
        (Harold Hunt).
      • 

        
    • Install xterm.termcap and xterm.terminfo when
        installing xterm (Torrey T. Lyons).
      • 

        
    • Fix some build issues on Cygwin/XFree86 (Suhaib
        Siddiqi).
      • 

        
    • Define CBAUD, when it's missing in xterm, on LynxOS
        (Stuart Lissaman).
      • 
      
    
    
    • 
  


  
Patch #156 - 2001/4/28 -
  XFree86 4.0.3


  
    
    
  • change order of selection-target types to make 8-bit xterm
    prefer UTF8_STRING to COMPOUND_TEXT (patch by Juliusz
    Chroboczek).
    • 

    
  • document -fa, -fs command-line
    options and faceName, faceSize
    resources which are used by the freetype library support.
    • 

    
  • if configure script finds freetype libraries, but imake
    definitions do not have the XRENDERFONT definition, define it
    anyway.
    • 

    
  • modify configure script check for freetype libraries to
    include <Xlib.h>, since an older version of
    the related headers relies on this (patch by Adam
    Sulmicki).
    • 
  


  
Patch #155 - 2001/4/20 -
  XFree86 4.0.3


  
    
    
  • correct return type of in_put() from patch #153 changes, which left it not wide
    enough for UTF-8 (patch by Bruno Haible).
    • 
  


  
Patch #154 - 2001/4/11 -
  XFree86 4.0.3


  
    
    
  • undo check for return value from pututline
    (used for debugging) since that function does not return a
    value on Slackware 3.6.
    • 

    
  • correct length in ScreenWrite, when rendering invisible
    text (patch by Sven Verdoolaege <skimo@kotnet.org>).
    • 

    
  • fixes/improvements for the i18nSelection
    resource from patch #153, by Bruno Haible:

      
      
        
    • add missing initialization for
        i18nSelection resource.
      • 

        
    • split-out the non-ICCM aspect of the
        i18nSelection resource as a new resource,
        brokenSelections.
      • 
      
    
    
    • 

    
  • add configure check for <time.h> and
    <sys/time.h>, to allow for Unixware 7,
    which requires both. If the configure script is not used, only
    <time.h> will be included as before (report
    by Thanh Ma).
    • 

    
  • fix redefinition of dup2,
    getutent, getutid,
    getutline and sleep functions on
    Unixware 7 (report by Thanh Ma
    <Thanh.Ma@casi-rusco.com>)
    • 

    
  • add a fall-back definition for __hpux, which
    is apparently not defined in some compilers on HPUX 11.0
    (reported by Clint Olsen).
    • 

    
  • change VAL_INITIAL_ERASE, which is used as a fallback for
    the "kb" termcap string to 8, since that matches
    the xterm terminal description (request by Alexander V
    Lukyanov).
    • 

    
  • correct an off-by-one in ClearInLine, which
    caused the erase-characters (ECH) control to display
    incorrectly (patch by Alexander V Lukyanov).
    • 

    
  • correct escape sequences shown in terminfo for shifted
    editing keys. The modifier code was for the control key rather
    than the shift key.
    • 
  


  
Patch #153 - 2001/3/29 -
  XFree86 4.0.3


  
    
    
  • increase PTYCHARLEN to 8 for os390, add some debugging
    traces for UTMP functions (patch by Paul Gilmartin).
    • 

    
  • correct an misplaced brace in
    SelectionReceived() (patch by Bruno Haible).
    • 

    
  • correct an assignment dropped in
    SelectionReceived() which made it not compile for
    wide-characters combined with debug traces.
    • 

    
  • correct typo, clarify description of 88- and 256-color
    controls (report by Bram Moolenaar).
    • 

    
  • correct a typo in ctlseqs.ms which caused DEC Locator
    control sequences using single quote "'" display grave "`"
    instead (reported by Paul Williams, apparently in patch
    #114).
    • 
  


  
Patch #152 - 2001/3/13 -
  XFree86 4.0.2


  
    
    
  • correct index in inner loop in VTInitI18N()
    from patch #151 changes, which resulted in infinite loop under
    some conditions (report/analysis by Paul Gilmartin).
    • 

    
  • remove spurious "%|" from terminfo sgr capabilities
    (report/analysis by Adam M Costello, Debian #89222).
    • 

    
  • add shell script to adjust list of dynamic libraries linked
    by resize when building with the standalone
    configure script. Otherwise it uses the same list as for xterm,
    which is excessive.
    • 

    
  • fix a few compiler warnings reported by the 20010305 gcc
    snapshot.
    • 
  


  
Patch #151 - 2001/3/10 -
  XFree86 4.0.2


  
    
    
  • alter the behaviour of selections in XTerm (patch by
    Juliusz Chroboczek). It is believed to follow the ICCCM +
    UTF8_STRING to the letter, both in UTF-8 and in eight-bit mode.
    From his description:

      
      
        
    • When compiled against XFree86 4.0.2, the patched XTerm
        will make the selection available as COMPOUND_TEXT, STRING
        or UTF8_STRING in both modes. It will request selections in
        the following order:

          
      UTF-8 mode: UTF8_STRING, TEXT, COMPOUND_TEXT,
          STRING.
      
          eight-bit mode: TEXT, COMPOUND_TEXT, UTF8_STRING,
          STRING.
      
        
      • 

        
    • When compiled against an earlier version of XFree86 (or
        compiled with OPT_UTF8_API=0), it will still obey the
        ICCCM, but will neither request nor provide UTF8_STRING in
        eight-bit mode, and neither TEXT nor COMPOUND_TEXT in UTF-8
        mode.
      • 

        
    • For compatibility with previous versions of XTerm, a
        resource i18nSelections is provided, please
        see the manpage for details. However, due to an unexpected
        combination of ICCCM extensions by various bits and pieces
        of the libraries, interacting with previous versions of
        XTerm will work in many locales even without this flag.
        (Please do not set this resource to true by default, as
        this would violate the ICCCM.)
      • 
      
    
    
    • 

    
  • improved error checking/reporting in VTInitI18N(), ensuring
    that lack of input method styles is treated distinctly from a
    mismatch.
    • 

    
  • remove an incorrect ifdef from patch #141 which suppressed
    overstriking to simulate bold font when xterm was compiled to
    support wide characters (report/analysis by Adam M Costello
    <amc@cs.berkeley.edu>, Debian #76404, Debian
    #77575).
    • 

    
  • modify RequestResize() function to
    save/restore window manager hints. Its call to
    XtMakeResizeRequest() had the undesirable
    side-effect of clearing window manager hints, e.g., when
    switching to 132-columns via DECCOLM escape sequence. Window
    manager hints make it simple to resize xterm in terms of
    character cells rather than pixels (reports by Christian
    Weisgerber, Debian #79939).

      
    This applies to the normal configuration. When built with
      toolbar support, the hints are applied to a different widget
      level (more work will be needed to make hints work with the
      toolbar).
    
    
    • 

    
  • fix a redefinition warning for resize.c on OpenBSD (patch
    by Christian Weisgerber).
    • 

    
  • change resource corresponding to -T option to
    match Xt library's -title, i.e.,
    .title rather than *title so the
    command-line options are interchangeable as documented (Debian
    bug report #68843).
    • 

    
  • add script used from autoconf'd makefile for installing
    manpages, since recent XFree86 changing the way section numbers
    are represented makes the install dependent on extra
    scripts.
    • 

    
  • add configure check for freetype libraries and configure
    option --disable-freetype to override this feature.
    • 

    
  • modify some configure script macros to avoid using
    changequote(), which has been rendered useless in the latest
    autoconf alpha 2.49c
    • 

    
  • update config.guess, config.sub to 2001-2-13
    • 

    
  • remove redundant/contradictory __CYGWIN__ definitions from
    resize.c
    • 

    
  • correct manpage typo introduced by X11R6.5 resync.
    • 
  


  
Changes from XFree86 4.0.2:


  
    
    
  • add definition of _POSIX_C_SOURCE for Solaris
    to make this compile with gcc -ansi -pedantic
    (report by <mark@zang.com>.
    • 
  


  
Patch #150 - 2000/12/29 -
  XFree86 4.0.2


  
    
    
  • move the binding for shifted keypad plus/minus, which
    invokes the larger-vt-font() and
    smaller-vt-font() actions, respectively, into the
    translations resource (suggested by Marius Gedminas
    <mgedmin@puni.osf.lt>).
    • 

    
  • modify configure script to support the
    --program-prefix, --program-suffix
    and --program-transform-name options (request by
    Alison Winters <alison@mirrabooka.com>).
    • 

    
  • fixes for wide/combining characters (Robert Brady):

      
      
        
    • fix a scrolling / combining characters display
        anomaly
      • 

        
    • fix a problem with double-width characters where if the
        primary font had no box-drawing characters, the right hand
        half of double-width characters was erased (reported by Yao
        Zhang <yzhang@sharemedia.com>).
      • 

        
    • fix special case of null byte for key handling in UTF-8
        locales.
      • 
      
    
    
    • 

    
  • modify logic that compares sizes of normal and bold fonts
    to be more forgiving of the font server's choice of bold font
    which must match the normal font's size. Now
    same_font_size() compares the height of the fonts
    rather than individually ascent and descent, and allows the
    bold font to be one pixel smaller than the normal font
    (addresses a report by Alan Citterman <alan@mticket.com>,
    who says that something in patches #146 to #148 made xterm more
    likely to overstrike bold fonts, and indirectly Debian bug
    report #76404, which reports the opposite).
    • 

    
  • make configure script use $CFLAGS and $CPPFLAGS
    consistently, including removing a chunk from configure.in
    which attempted to save/restore $CPPFLAGS while processing
    value set by the --x-includes option, but lost values set in an
    intervening AC_CHECK_HEADERS. This change modifies macros
    CF_ADD_CFLAGS, CF_ANSI_CC_CHECK and CF_X_TOOLKIT, as well as
    removing variables IMAKE_CFLAGS and X_CFLAGS from the generated
    makefile (the AC_CHECK_HEADERS problem was reported by Albert
    Chin-A-Young <china@thewrittenword.com<).
    • 

    
  • correct a comparison in SELECTWORD case of ComputeSelect(),
    which resulted in a word-selection wrapping past the first
    column without checking the first column's character class
    (reported by Christian Lacunza
    <celacunza@netscape.net>
    • 

    
  • correct a logic in UTF-8 mode for selecting double-width
    characters; a combining character was omitted (patch by Markus
    Kuhn).
    • 

    
  • add feature to pop (raise) window when a bell is received
    (patch by Gael Roualland
    <gael.roualland@dial.oleane.com>).
    • 

    
  • add __NetBSD__ and __OpenBSD__ to special-case in
    xterm_io.h for USE_POSIX_TERMIOS definition (patch by Christian
    Weisgerber).
    • 

    
  • move special-case HPUX include for <sys/bsdtty.h> to
    xterm_io.h to define TIOCSLTC, making HAS_LTCHARS defined for
    HPUX 10.20 (report by Bruno Betro).
    • 
  


  
Patch #149 - 2000/12/6 -
  XFree86 4.0.1h


  
    
    
  • restructured includes for termios.h,
    termio.h and related definitions for main.c,
    os2main.c, screen.c and resize.c so they will share equivalent
    definitions in a new header xterm_io.h. This is
    intended to solve some problems mainly for HPUX which appear to
    arise from inconsistent definitions for SIGWINCH- and
    HAS_LTCHARS-related symbols (reports by Bruno Betro, Jeremie
    Petit and Clint Olsen).
    • 

    
  • improve usability of double-width fonts by allowing normal
    fonts to be given as double-width (from a patch by Fabrice
    Bellard <bellard@email.enst.fr>).
    • 

    
  • correct a few compiler warnings in TRACE() macros for
    signed/unsigned variable differences (reported by Clint
    Olsen).
    • 

    
  • make configure script use $CFLAGS and $CPPFLAGS more
    consistently, i.e., by using CF_ADD_CFLAGS in CF_ANSI_CC
    macro.
    • 

    
  • expanded description of environment variables in
    manual-page.
    • 

    
  • modify OPT_TCAP_QUERY feature to always return the termcap
    or terminfo capability string in the response, and to
    read/write the names in hexadecimal form to allow for the
    special case of termcap's k; name (patch by Bram
    Moolenaar).
    • 

    
  • add OPT_SAME_NAME and OPT_TCAP_QUERY to xtermcfg.hin, so
    the corresponding configure options work (patch by Bram
    Moolenaar).
    • 

    
  • resync with XFree86 4.0.1g:

      
      
        
    • Rewrite Xft library for Render extension/core text and
        font management Change xterm to use new interface (Keith
        Packard).

Patch #148 - 2000/10/31 -
  XFree86 4.0.1d


  
    
    
  • document logfile options in man-page.
    • 

    
  • correct spelling of -samename option in help
    message.
    • 

    
  • add configure script option
    --enable-tcap-query (request by Bram
    Moolenaar).
    • 

    
  • add a "Co" or "colors" entry to the OPT_TCAP_QUERY feature
    (patch by Bram Moolenaar).
    • 

    
  • patch by Kiyokazu Suto <suto@ks-and-ks.ne.jp>:

      
      
        
    • add support for bold font for double width characters.
        The font name may be specified with the command line option
        -fwb or with resource
        wideBoldFont (class
        WideBoldFont).
      • 

        
    • correct underlining of double width character string,
        which was drawn only half width.
      • 

        
    • correct binary search of precomposed character table,
        which may return wrong result when int is just
        32 bits.
      • 
      
    
    
    • 

    
  • some changes to align terminfo with ncurses 5.2:

      
      
        
    • remove xtermm description, retaining xterm-mono since
        the former conflicts with ncurses.
      • 

        
    • modify initialization and reset strings to avoid
        putting the save/restore cursor operations bracketing
        changes to video attributes, since the changes could be
        lost when the cursor is restored. This affects xterm-r6 and
        xterm-8bit (the xterm-xfree86 entry uses the soft-reset
        feature which resets scrolling margins and origin mode
        without requiring us to save/restore the cursor
        position).
      • 

        
    • make a few entries explicitly inherit from
        xterm-xfree86 rather than xterm: xterm-rep, xterm-xmc,
        xterm-nrc
      • 
      
    
    
    • 

    
  • ensure that sign-extension does not affect
    ctype macros by using CharOf() macro
    to coerce the parameter to an unsigned char.
    • 

    
  • resync with XFree86 4.0.1d:

      
      
        
    • Add primitive support in xterm for Xft based fonts
        (Keith Packard). The changes are ifdef'd with
        -DXRENDERFONT.

Patch #147 - 2000/10/26 -
  XFree86 4.0.1c


  
    
    
  • correct implementation of ptyInitialErase: the
    value assigned to initial_erase was for the
    control terminal, which is correct as far as it goes. But there
    was no following test for the pseudo-terminal's erase value,
    which would overwrite the default obtained from the control
    terminal (reported by Christian Weisgerber
    <naddy@mips.inka.de>).
    • 

    
  • modify check for printable-characters in OSC string to use
    xterm's ansi_table rather than isprint() macro, to isolate this
    check from locale settings. This fixes a problem using 8-bit
    characters to set the title (reported by Ricardas Cepas
    <rch@richard.eu.org>).
    • 

    
  • modify sample scripts to check for printf before print,
    since the latter is not as well standardized (e.g., on
    Linux).
    • 

    
  • updated config.sub, config.guess to reflect changes on
    subversions.gnu.org
    • 
  


  
Patch #146 - 2000/9/12 -
  XFree86 4.0.1c


  
    
    
  • correct two instances overlooked from patch #141 which
    assumed UTF-8 mode without checking, causing a core dump in
    non-UTF-8 mode (one instance was reported by Tommi Virtanen
    <tv@debian.org>).
    • 

    
  • correct a problem selecting from the scrollback buffer in
    UTF-8 mode by changing remaining getXtermCell() calls to
    XTERM_CELL() as in the non-UTF-8 cases (report by Markus Kuhn,
    patch by Robert Brady).
    • 
  


  
Patch #145 - 2000/9/11 -
  XFree86 4.0.1c


  
    
    
  • changes for UTF-8 configuration (Robert Brady):

      
      
        
    • doublewide characters don't lose their accents when the
        cursor moves onto or from them (a visual bug)
      • 

        
    • fix logic in addXtermCombining, which mean that if the
        low byte of a cell's first combining char was 0, a
        following combining char would go into combining slot 1,
        not 2.
      • 

        
    • modify logic for cut-buffers so UTF-8 data is first
        converted to Latin1.
      • 

        
    • collapse surrogates, 0xfffe, 0xffff to UCS_REPL.
      • 

        
    • modify to allow xterm to to show combining characters
        attached to doublewidth characters.
      • 

        
    • correct bug in linewrap with -u8 option (reported by
        Andreas Koenig <andreas.koenig@anima.de>).
      • 
      
    
    
    • 

    
  • several changes to PTY logic (based on request by Tim Ryan
    <timryan@nortelnetworks.com>).

      
      
        
    • modify treatment of -S option to to make
        it work with Unix98 PTY's.
      • 

        
    • restore sense of IsPts flag in get_pty(),
        which was lost in Unix98 changes.
      • 

        
    • use new functions my_pty_id() and
        my_pty_name() to simplify/fix strings used for
        utmp, wtmp identifiers.
      • 

        
    • simplify get_pty() function, making it
        have a single return point so its inputs/outputs can be
        identified.
      • 
      
    
    
    • 

    
  • update config.guess and config.sub and scripts to my
    20000819 patch, adding cases for OS/2 EMX.
    • 

    
  • add special case for os390 compiler options to configure
    script (patch by Paul Gilmartin)
    • 

    
  • fix some unused-variable compiler warnings (reported by
    Zdenek Sekera).
    • 

    
  • split-out some string functions into xstrings.c, to use
    them more consistently among main.c, os2main.c and
    resize.c
    • 

    
  • align termcap/terminfo files, adding entries to make them
    match. The termcap entries are necessarily less complete than
    the terminfo, to fit within 1023 character per entry.
    • 

    
  • add terminfo entry for xterm-sco (SCO function keys).
    • 

    
  • modify same_font_name() to properly handle
    wildcard introduced in bold_font_name(), making
    comparison for different fonts succeed when only the normal
    font is specified. This is needed to decide if 1-pixel offset
    should be used. (reported in a newsgroup by Bart Oldeman
    <enbeo@enbeo.resnet.bris.ac.uk>)
    • 

    
  • correct preprocessor line for OPT_WIDE_CHARS in
    drawXtermText() from patch #141 which resulted in overstriking
    for bold fonts not working.
    • 

    
  • correct Imakefile from 4.0.1c resync so UTF-8 modules are
    in UTF8SRC, UTF8OBJ lists, allowing build without UTF-8
    support.
    • 
  


  
Patch #144 - 2000/8/23 -
  XFree86 4.0.1b


  
    
    
  • remove a spurious assignment in ScreenWrite() from Robert
    Brady's patch which set a null at the "end" of the buffer to be
    written. That made the autowrap feature write a blank in the
    first column for the non-UTF-8 configuration, rather than the
    actual character (reported by Alan Citterman
    <alan@mticket.com>).
    • 
  


  
Patch #143 - 2000/8/19 -
  XFree86 4.0.1b


  
    
    
  • add a check to ensure that -class command-line
    option is not confused with -c (reported by Paul
    Townsend <aab@aab.cc.purdue.edu>).
    • 
  


  
Patch #142 - 2000/8/18 -
  XFree86 4.0.1b


  
    
    
  • correction to precompose scripts, so 0061 + 0300 will now
    be really be displayed as 00C0 (patch by Robert Brady
    <robert@susu.org.uk>).
    • 

    
  • correct macro ClassSelects() in button.c, used to hide
    ifdef's for OPT_WIDE_CHARS in patch #141 (reported by Andreas
    Paul <paula@informatik.tu-muenchen.de>).
    • 

    
  • change wcwidth.h to include stddef.h rather than wchar.h,
    which is not present on OpenBSD and FreeBSD (reported by
    Christian Weisgerber and Bram Moolenaar).
    • 

    
  • newer config.sub and config.guess, from lynx
    2.8.4dev.7
    • 
  


  
Patch #141 - 2000/8/14 -
  XFree86 4.0.1b


  
    
    
  • changes for doublewidth and combining characters, from
    http://www.ecs.soton.ac.uk/~rwb197/xterm/ (integrated patch by
    Robert Brady). In this context, doublewidth refers to 16-bit
    character sets which may have glyphs occupying two cells.
    • 

    
  • add command-line option -class, which allows
    one to override xterm's resource class. Also add resource file
    UXTerm.ad, which simplifies using xterm for both
    8-bit character sets and UTF-8.
    • 

    
  • fixes/improvements to OPT_TCAP_QUERY logic (patches by Bram
    Moolenaar, Stephen P Wall).
    • 
  


  
Patch #140 - 2000/7/23 -
  XFree86 4.0.1


  
    
    
  • modify Makefile.in to circumvent GNU make's built-in suffix
    rule for ".sh" which confuses install.sh with the "make
    install" target (report/patch by Paul Gilmartin).
    • 

    
  • implement an experimental control sequence which an
    application may use to query the terminal to determine what
    sequence of characters it would send for a given function key.
    This is ifdef'd with OPT_TCAP_QUERY (request by Bram
    Moolenaar).
    • 

    
  • add /usr/local to search path in CF_X_ATHENA configure
    macro to build with Xaw3d on OpenBSD (patch by Christian
    Weisgerber).
    • 

    
  • add missing #undef HAVE_TERMIO_C_ISPEED to
    xtermcfg.hin, omitted in patch #133 fix for IRIX 6.5 baudrate
    (report by Alain Filbois <Alain.Filbois@loria.fr>).
    • 

    
  • correct a few errors in xterm.man: font in filename example
    for Tektronix emulation, and description of -nul/+nul
    command-line options (report by Eric Fischer
    <enf@pobox.com>).
    • 

    
  • update config.guess and config.sub, from tin and lynx.
    • 
  


  
Patch #139 - 2000/6/17 -
  XFree86 4.0d


  
    
    
  • back out change to -name command-line option,
    restoring its original behavior (as noted by David Madore, the
    correct interpretation of this option is the application
    instance rather than the application class).
    • 
  


  
Patch #138 - 2000/6/15 -
  XFree86 4.0c


  
    
    
  • workaround for fixed fonts which are generated from Unicode
    fonts: they omit glyphs for some xterm's less-used line-drawing
    characters, which caused xterm to set a flag telling it to use
    only its internal line-drawing characters. Do not set the flag
    (it can be set from the popup menu), and xterm will generate
    only the line-drawing glyphs which actually are missing.
    
    Otherwise, when used for large fonts, xterm may generate a
    2-pixel wide line, which can leave dots on the screen.
    • 

    
  • restore first line of 256colres.pl, omitted in 4.0c
    diffs.
    • 
  


  
Patch #137 - 2000/6/10 -
  XFree86 4.0b


  
    
    
  • make command-line -name option work as
    documented. Apparently this was lost in X11R5 when coding to
    use XtAppInitialize.
    • 

    
  • limit numeric parameters of control sequences to 65535 to
    simplify checks for numeric overflow.
    • 

    
  • change index into UDK list to unsigned to guard against
    numeric overflow making the index negative (Taneli Huuskonen
    <huuskone@cc.helsinki.fi>).
    • 

    
  • change sun function-keys resource name to
    sunFunctionKeys to work around redefinition of the
    token sun by xrdb on Solaris. Similarly, renamed
    resource sun keyboard to
    sunKeyboard (Stephen P Wall).
    • 

    
  • change similar resource names for HP and SCO to avoid
    potential conflict with xrdb symbols on other systems, as well
    as for consistency.
    • 

    
  • reorganized the install targets in the autoconf'd Makefile,
    adding install-app, install-bin, install-dirs and install-man.
    The app-defaults class can be overridden by setting the make
    variable 'CLASS', simplifying customization of xterm as a
    Unicode terminal, e.g., CLASS=UXTerm.
    • 

    
  • add limit checks to ClearInLine(),
    ScrnInsertChar(), ScrnDeleteChar() to
    correct potential out-of-bounds indexing (prompted by Debian
    bug report #64713, which reported a problem with ICH escape
    sequences).
    • 

    
  • updates to config.sub and config.guess Kevin Buettner
    <kev@primenet.com> for elf64_ia64 Bernd Kuemmerlen
    <bkuemmer@mevis.de> and MacOS X.
    • 

    
  • for os390, add check for errno set to ENODEV on failure to
    open /dev/tty when there is no controlling terminal (patch by
    Paul Gilmartin).
    • 

    
  • fixes for building on Digital Unix 4.0 and AIX 4.2 (patch
    from H Merijn Brand <h.m.brand@hccnet.nl>).
    • 

    
  • modify DECRQSS reply for DECSCL to additionally report if
    the terminal is set for 8-bit controls.
    • 
  


  
Patch #136 - 2000/6/3 -
  XFree86 4.0b


  
    
    
  • add a resource (limitResize) limiting resizing
    via the CSI 4 t and CSI 8 t sequences.
    • 

    
  • ignore out-of-bounds resize requests, i.e., where
    sign-extension or truncation of the parameters would
    occur.
    • 
  


  
Patch #135 - 2000/5/29 -
  XFree86 4.0b


  
    
    
  • remove code introduced in #134 which made some backgrounds
    bold.
    • 

    
  • minor correction to format of updated $TERMCAP when adding
    kb capability for ptyInitialErase
    logic.
    • 

    
  • improved test for SVR4 definition.
    • 
  


  
Patch #134 - 2000/5/28 -
  XFree86 4.0b


  
    
    
  • update URL's and mailing addresses, moved to
    http://dickey.his.com and dickey@herndon4.his.com
    • 

    
  • correct missing quotes in CF_TTY_GROUP configure script
    macro in case the script is run in batch mode.
    • 

    
  • modify ownership-check of log file to ignore the group
    ownership. Otherwise xterm cannot create logfiles in
    directories with set-gid permissions.
    • 

    
  • simplify the logic that reads termcap data.
    • 

    
  • add fallback definition for B9600 in case line speed
    definition for 38400 is missing (report by Jack J Woehr
    <jwoehr@ibm.net>, for OpenBSD 2.6).
    • 

    
  • fix: Set highlightColor, and select a region containing the
    text cursor. If the window loses focus, the cursor becomes
    hollow, with the region inside the cursor being
    background/foreground, unlike the rest of the selection, which
    is foreground/highlight (patch by Ross Paterson
    <ross@soi.city.ac.uk>).
    • 

    
  • add configure script tests to define SVR4, SYSV and
    USE_POSIX_WAIT, which enables xterm to compile on Solaris 7 and
    SCO Openserver without imake, though there are still a few
    features for the latter which require sco to be
    predefined.
    • 

    
  • patches from Stephen P Wall:

      
      
        
    • add support for two Sun-specific function keys. These
        keys are labeled F11 and F12 on Sun Type 5 keyboards, but
        return SunXK_F36 and SunXK_F37. Support will only be
        compiled in if the header file <X11/Sunkeysym.h>
        exists and contains the appropriate symbol definitions. The
        keycodes for the DEC keycodes were arbitrary unused codes,
        but the ones for the Sun keycodes are what cmdtool and
        shelltool actually send.
      • 

        
    • add colorRV and colorRVMode
        resources to allow specifying a color to use for reverse
        video, similar to the existing UL, BD, and BL modes.
      • 

        
    • add alwaysUseMods resource, to override
        check if alt or meta modifiers
        are used in translations resource. Revamped
        the code to calculate the modifier value, and included Meta
        if alwaysUseMods is TRUE, using values 9-16.
      • 
      
    
    
    • 

    
  • fixes for os390 (Paul Gilmartin):

      
      
        
    • regularize the definition of CONTROL() and remove an
        acknowledged "trial and error" table.
      • 

        
    • translate "^?" into A2E(0177) which is the EBCDIC "DEL"
        rather than plain 0177 which is the EBCDIC quotation
        mark.
      • 

        
    • modify xtermMissingChar() so that EBCDIC
        codes 128-159 are not rendered as blanks by X server
        running on Solaris, which sees those as control
        characters.
      • 

        
    • make debugging traces (configure --enable-trace) work
        properly with EBCDIC.
      • 
      
    
    
    • 
  


  
Patch #133 - 2000/5/2 -
  XFree86 4.0a


  
    
    
  • add substitutions in autoconf'd Makefile for CPPFLAGS,
    LDFLAGS and AWK (reported by Neil Bird).
    • 

    
  • correct uninitialized childstat variable from
    patch #131 in creat_as() function, which caused
    logging to not work on Solaris, whose waitpid()
    function does not initialize its parameter. Add check for EINTR
    on return from waitpid() as well (reported by Neil
    Bird <neil.bird@rdel.co.uk>).
    • 

    
  • remove a redundant check for working setuid()
    function introduced in patch #132. Greg Smith reports that this
    does not work as intended on os390.
    • 

    
  • change line speed from 9600bd to 38400bd, to accommodate
    people who mistakenly use $TERM set to vt100, to
    reduce the effect of padding associated with this terminal
    type.
    • 

    
  • add configure script check for IRIX 6.5's redefinition of
    baud rates associated with struct termio, to
    correct a situation where the baud rate was initialized to zero
    (reported by Andrew Isaacson <adi@lcse.umn.edu>).
    • 

    
  • remove unused configure script check for VDISABLE.

Patch #132 - 2000/4/11 -
  XFree86 4.0a


  
    
    
  • undo an incorrect change from patch #113 caused the right
    scrollbar to be positioned incorrectly when re-enabling it
    (analysis by D Roland Walker).
    • 

    
  • add ctrlFKeys resource, replacing constant for adjusting
    control-F1 to control-F12 to VT220-style F10-F20. The resource
    changes the constant 12 to a default value of 10 (request by
    Jim Knoble <jmknoble@pobox.com>).
    • 

    
  • correct ifdef'ing for conflict between definitions in AIX's
    <sys/select.h> and <X11/Xpoll.h> (reported by Clint
    Olsen).
    • 

    
  • add checks for return-values of getutid(), initgroups() and
    setuid() in main.c, as well as modifying ifdef's for __osf__ to
    include tty-group and WTMP logic (adapted from patch by Paul
    Szabo <psz@maths.usyd.edu.au>)
    • 

    
  • modify resize.c to build and work on os390 (uses EBCDIC)
    (adapted from patch by Phil Sidler
    <Phil.Sidler@airborne.com>)
    • 

    
  • use Ires(), Bres() and Sres() macros to simplify resource
    list in charproc.c
    • 

    
  • resync with XFree86 4.0a:

      
      
        
    • correct a typo in os2main.c (Holger Veit, from
        4.0a).
      • 
      
    
    
    • 
  


  
Patch #131 - 2000/3/3 -
  XFree86 3.9.18b


  
    
    
  • improve logfile security (integrated patch by Branden
    Robinson)

      
      
        
    • make the creat_as() function more strict
        by using O_EXCL rather than O_APPEND.
      • 

        
    • fixes to make DEBUG ifdef's compile/run, including
        making the debug logfile more unique by appending a
        timestamp to its name.
      • 

        
    • include <term.h> in resize.c, to fix a
        missing-prototype warning.
      • 
      
    
    
    • 

    
  • modified creat_as() a little more, retaining
    the ability to append to a logfile If the user specifies the
    name. Also, check if the opened file (which patch #130 ensures
    is owned by the effective user) is not writable by other
    users.
    • 

    
  • use creat_as() logic to make tek4014
    screen-copy more secure (noted by Branden Robinson).
    • 

    
  • ifdef'd some of Branden's changes to build/work on older
    machines.
    • 

    
  • correct missing initialization of the .mode
    flag in ColorRes struct, from patch #129. This
    worked on Linux because malloc() zeroes memory on
    that platform (reported by Christian Weisgerber).
    • 

    
  • modify logic for deleteIsDEL resource so it
    has internally 3 states: unspecified, true and false. If
    unspecified, the keyboard type determines whether the Delete
    key transmits <ESC>[3~ or \177,
    and the popup menu entry reflects the internal state.
    Otherwise, the popup menu entry overrides the keyboard type
    (suggested by Dr Werner Fink, to make it simpler to set
    resources that imitate the legacy X11R6 xterm).
    • 
  


  
Patch #130 - 2000/3/1 -
  XFree86 3.9.18a


  
    
    
  • modify scroll-forw() and
    scroll-back() actions, adding a third parameter
    which will direct xterm to ignore the action when mouse
    reporting is enabled. This is needed for the wheel mouse to be
    used to report to the application rather than scroll the
    window.
    • 

    
  • add menu entry and action to allow disabling xterm's
    assumption that the current font contains line-drawing
    characters if the font cells 1-31 are nonempty. Some fonts may
    have other characters (reported by Bruno Betro
    <bruno@iami.mi.cnr.it>).
    • 

    
  • add a check in creat_as() to ensure that the
    user really owns the logfile that has been opened.
    • 

    
  • add logic to implement SCO function-keys. (This is really
    incomplete, since I intend to revisit this and make xterm able
    to emulate scoansi better than just the function-keys).
    • 

    
  • add configure script option --enable-sco-fkeys, minor
    related fixes (patch by Dr Werner Fink).
    • 

    
  • fix typos in ctlseqs.ms (reported by Bram Moolenaar)
    • 

    
  • fix typo in sinstall.sh default for $TST_PROG (reported by
    Paul Gilmartin <pg@sweng.stortek.com>)
    • 
  


  
Patch #129 - 2000/2/26 -
  XFree86 3.9.18a


  
    
    
  • improve initialization of ANSI colors by delaying
    allocation until each color is first used.
    • 

    
  • remove ifdef that prevented colorBD/colorUL/colorBL
    resources from working when 256-color configuration was built
    (reported by Todd Larason).
    • 

    
  • fix some minor inconsistencies in terminfo (Debian
    #58530).
    • 
  


  
Patch #128 - 2000/2/17 -
  XFree86 3.9.18


  
    
    
  • correct logic for oldXtermFKeys resource,
    fixes a core dump when attempting to set it from the
    command-line (reported by Dr Werner Fink).
    • 

    
  • correct ifdef for meta-sends-escap so configure
    --disable-num-lock builds.
    • 
  


  
Patch #127 - 2000/2/12 -
  XFree86 3.9.17e


  
    
    
  • add resource, popup menu entry and control sequence to
    allow changing the Delete key to send either DEL or the
    VT220-style Remove escape sequence.
    • 

    
  • remove logic for metaSendsEscape that would allow xterm to
    send <ESC>[3~ before a function key that
    would begin with <ESC>[3~ (request by
    Christian Weisgerber).
    • 

    
  • add missing action and documentation for
    meta-sends-escape.
    • 

    
  • correct a few typos in ctlseqs.ms (incorrect code for Cyan
    color)
    • 
  


  
Patch #126 - 2000/2/8 -
  XFree86 3.9.17c


  
    
    
  • ensure that xterm will automatically activate the UTF-8
    mode whenever the name of the locale environment variable
    suggests that a UTF-8 locale is in use (patch by Markus Kuhn).
    This will help that by simply setting LC_CTYPE an entire system
    can be switched over to UTF-8, without users having to remember
    the UTF-8 command line options ("-u8", etc.) of the various
    applications. Command line options and X resource entries can
    still be used to override this default choice.
    • 

    
  • add old function-keys control sequences and popup menu
    entry, for compatibility with legacy X11R6 xterm.
    • 

    
  • revert translation of editing keypad "Delete" key to legacy
    \177.
    • 

    
  • simplify the color-resource data expressions with macro
    COLOR_RES, for later use in restructuring color
    initialization.
    • 

    
  • change encoding of wheel mouse (buttons 4 and 5) to avoid
    conflict with legacy mouse modifiers (suggested by Bram
    Moolenaar).
    • 
  


  
Patch #125 - 2000/1/31 -
  XFree86 3.9.17c


  
    
    
  • make this work on OpenVMS (integrated patch by David
    Mathog).
    • 

    
  • rename some functions, e.g., Index to
    xtermIndex so that ports such as VMS which link
    externals ignoring case will not have library conflicts
    (reported by David Mathog).
    • 

    
  • correct logic of do_reversevideo(), which did
    not update the corresponding popup menu check mark (reported by
    David Mathog, this was a detail overlooked in patch #94).
    • 

    
  • change TRACE macro so semicolon is not within definition,
    making indent and similar programs work better.
    • 

    
  • add depend rule to Makefile.in
    • 

    
  • modify logic of boldColors resource to suppress it if an
    extended color control has been used, e.g., for 88-color or
    256-color mode (patch by Todd Larason).
    • 

    
  • revise logic that handles menus and input translation for
    keyboard type so only one can be selected at a time.
    • 

    
  • restore kdch1=\177 for the Sun function-key type, and make
    the the Delete key send DEL (\177) if the oldXtermFKeys
    resource is set.
    • 

    
  • rephrase logic and ifdef's for POSIX VDISABLE to avoid
    preprocessor expression that will not compile on NetBSD/x86
    1.4.1 (reported by Takaaki Nomura
    <amadeus@yk.rim.or.jp>).
    • 
  


  
Patch #124 - 2000/1/27 -
  XFree86 3.9.17b


  
    
    
  • change coding of editing keypad's "Delete" key to
    <escape>[3~, in the default (Sun/PC) keyboard mode. This
    makes the terminfo kdch1 capability independent of the coding
    of the backarrow key, which sends either backspace (8) or DEL
    (127). The reason for doing this (compatibility with the
    screen program) outweighs the choice of DEL (127)
    which was used in X11R5/X11R6 xterms. The screen
    program translates whatever matches kdch1 into
    <escape>[3~, even if it happens to be the stty erase
    character.
    • 

    
  • add encoding for control/?, to work around xmodmap or key
    translations which may confuse backspace and delete. A
    control/? will send DEL (127), and a control/H will of course
    send backspace (8).
    • 

    
  • add encoding for kcbt to <escape>[Z (fixes Debian
    #54840).
    • 

    
  • minor correction to logic that encodes Sun and DEC function
    keys to avoid sending an escape sequence if the key symbol is
    not found in xterm's lookup table.
    • 

    
  • simplify ifdef's in main.c for POSIX VDISABLE so the "^-"
    pattern is more likely to be implemented when imake
    configures xterm (fixes Debian #55105).
    • 

    
  • change manpage to make it clearer what codes are sent by
    the backarrow key.
    • 
  


  
Patch #123 - 2000/1/22 -
  XFree86 3.9.17a


  
    
    
  • add a note reserving OSC 51 for use in Emacs shell (request
    by Rob Mayoff <mayoff@dqd.com>).
    • 

    
  • correct a missing backslash in xterm-vt220 termcap.
    • 

    
  • cleanup remaining quoted includes, preferring bracketed
    form.
    • 

    
  • minor configure-script macro updates from tin and
    vile.
    • 

    
  • add configure-script option for using utempter library,
    adapted from Redhat 6.1 patch for XFree86 3.3.5
    • 

    
  • resync with XFree86 3.9.17a:

      
      
        
    • correction to QNX support (Frank Guangxin Liu)
      • 

        
    • some cosmetic changes that did not correct any reported
        problems.
      • 
      
    
    
    • 
  


  
Patch #122 - 1999/12/28 -
  XFree86 3.9.16f


  
    
    
  • move the suggested wheel-mouse button translations into
    charproc.c to simplify customization. Correct some minor logic
    errors in the support for buttons 4 and 5, used for wheel mice
    (reported by Bram Moolenaar).
    • 

    
  • implement metaSendsEscape resource, with
    corresponding control sequence and menu entry. Like
    eightBitInput, this causes xterm to send ESC prefixing
    the given key, but applies to all keys and is independent of
    the 8-bit/7-bit terminal setting. (requests by Alexander V
    Lukyanov and Marc Feeley).
    • 

    
  • correct potential indexing with negative subscript in
    udk_lookup(), (reported by Ian Collier
    <Ian.Collier@comlab.ox.ac.uk>).
    • 

    
  • modify configure script that sets TERMINFO_DIR to use
    ${prefix} rather than /usr if the --prefix option was specified
    (request by Zdenek Sekera <zs@sgi.com>).
    • 

    
  • modify checks for repeat-character control sequence to test
    the character class against xterm's state table, rather than
    the isprint() macro (patch by Alexander V Lukyanov).
    • 

    
  • change several functions to macros to improve speed
    • 

    
  • two corrections to simulation of bold font via
    overstriking:

      
      
        
    • use clipping to avoid leaving trash at end of the text,
        and
      • 

        
    • add brackets so wide-character logic does not
        fall-through into the overstriking logic (reported by Marc
        Feeley <feeley@IRO.UMontreal.CA>)
      • 
      
    
    
    • 

    
  • add several entries to termcap file to make it have the
    same set of aliases as the terminfo file.
    • 

    
  • scale the color values used for xterm-256color terminfo
    entry to 0..1000, as expected by ncurses.
    • 

    
  • change xterm-r6 terminfo definitions for F1-F4 to match
    program.
    • 

    
  • Add QNX/Neutrino support (Frank Guangxin Liu
    <frank@ctcqnx4.ctc.cummins.com>)
    • 
  


  
Patch #121 - 1999/11/14 -
  XFree86 3.9.16c


  
    
    
  • change label on "Sun/PC Keyboard" popup menu entry to
    "VT220 Keyboard", since the checked state corresponds to VT220
    rather than Sun/PC.
    • 

    
  • add configure test CF_UTMP_UT_XSTATUS to handle the
    variants of utmp exit status (reports by Dave Ellement, Jeremie
    Petit, Tomas Vanhala).
    • 

    
  • amend treatment of ALT key (see patch
    #94) so that if ALT is used as a modifier in key
    translations, then no parameter will be sent in escape
    sequences for Sun/PC function keys (request by Dr Werner
    Fink).
    • 

    
  • modify default for OPT_I18N_SUPPORT to assume that
    XtSetLanguageProc() is available in X11R5.

      
    Caveat: XtSetLanguageProc() was added fairly
      late in the X11R5 patches, and some vendors shipped buggy
      versions of this function (request by Tomas Vanhala).
    
    
    • 

    
  • correct configure macro CF_SYSV_UTMP to test-link with
    functions consistent with the header, e.g., getutent() for
    utmp.h and getutxent() for utmpx.h (reported by Greg
    Smith).
    • 

    
  • modify terminfo entry for xterm-xfree86 to
    reflect modifiers for shift and control (from a patch by
    Alexander V Lukyanov).
    • 

    
  • modify terminfo entry for xterm-sun to match
    the function-key definitions in ncurses. The pageup/pagedown
    and related function keys correspond to the Sun keyboard, which
    does not necessarily correspond with X's notion of those
    keys.
    • 

    
  • modify treatment of XK_Delete keysym so it transmits
    parameterized VT220-style <ESC>[3~ if
    modifiers (shift, control alt) are given (request by Alexander
    V Lukyanov).
    • 

    
  • corrected misspelled resource name in command-line option
    for HP function keys.
    • 
  


  
Patch #120 - 1999/10/28 -
  XFree86 3.9.16c


  
    
    
  • refine the change to SGR_Background() in patch
    #119, by not flushing the pending scrolling operation if the
    background color is not actually changing. This combination
    occurs when using color-ls to display a long listing, since
    each line ends with an SGR0 which affects only the foreground
    color. The unnecessary flushing made it noticeably slower
    (reported by D Roland Walker <walker@pobox.com>).
    • 

    
  • remove obsolete documentation about modifiers which can be
    returned in mouse tracking mode, and modify logic to ignore
    modifiers other than the existing ones, e.g., NumLock (prompted
    by discussions with Christian Weisgerber and Brad Pepers
    <brad@linuxcanada.com>).
    • 

    
  • use free bit from obsolete shift-modifier coding of mouse
    tracking button events to encode buttons 4 and 5, e.g., for a
    wheel mouse (requests by Brad Pepers and Bram Moolenaar).
    • 

    
  • correct a place where the ptyInitialErase logic did not set
    the backarrowKey state, and modify it further to use tgetstr()
    rather than parse the termcap data returned from tgetent() so
    the ptyInitialErase logic will work when xterm is linked with a
    terminfo library (based on a patch by Dr Werner Fink
    <werner@suse.de>).
    • 

    
  • fix definition of HAVE_UTMP_UT_HOST for ISC configuration
    (patch by Michael Rohleder).
    • 

    
  • improve configure script's utmp tests (based on reports by
    Greg Smith for os390, and David Ellement for HPUX).
    • 

    
  • modify sinstall.sh to use uid=0 rather than 'root' to
    determine if the installer is privileged. This is needed on
    some systems since more than one account may be privileged
    (report by Greg Smith).
    • 

    
  • add an application resource, messages (and a
    corresponding -/+mesg option) which controls the initial
    permission on the terminal: if messages is set to true (the
    default), behavior is as without the patch; if it is set to
    false (as per -mesg), the terminal is opened in mode 0600, thus
    producing the effect of the mesg n command. This
    is useful for users who want to redirect all their messages to
    one particular xterm: it is more pleasant to do this with xterm
    resources than with explicit calls to the mesg
    program (patch, description by David Madore
    <david.madore@ens.fr>).
    • 
  


  
Patch #119 - 1999/10/16 -
  XFree86 3.9.16c


  
    
    
  • add responses (DA and DSR) for DEC locator mode
    • 

    
  • add coding for ANSI color to DA response
    • 

    
  • implement UTF-8 translation for Media Copy (print)
    operations.
    • 

    
  • implement vt320 control sequences for Print Composed Main
    Display and for Print All Pages. The latter directs xterm to
    print the current screen as well as the scrollback buffer.
    • 

    
  • correct error in _GNU_SOURCE configure test, which left it
    always defined.
    • 

    
  • add more information, i.e., with strerror for some system
    calls in the main program which may fail due to insufficient
    permissions (prompted by a problem report for -C
    by Jeremie Petit <Jeremie.Petit@digital.com>).
    • 

    
  • add workaround for conflict between <X11/Xpoll.h> and
    <sys/select.h> on AIX 4.3 (Richard Griswold
    <griswold@acm.org>).
    • 

    
  • add configure script test to resolve conflict between
    between <X11/Xpoll.h> and <sys/select.h>
    • 

    
  • modify translation of UTF-8 sequences to reject "overly
    long" variations (patch by Markus Kuhn).
    • 

    
  • remove utf8controls resource, since Markus'
    change removes the corresponding logic.
    • 

    
  • correct a case where colors were not rendered properly.
    This happened when an application inserted several lines, then
    changed colors. If this was done all in one write, then there
    would be no intervening refresh, and the new color was applied
    to the pending scrolling operation which was awaiting the next
    refresh (reported by Stephane Chazelas
    <Stephane_Chazelas@Raytheon.com>).
    • 
  


  
Patch #118 - 1999/10/5 -
  XFree86 3.9.16b


  
    
    
  • refine configure test for utmp versus utmpx, to build on
    HP-UX 10.x (reported by David Ellement).
    • 

    
  • move the configure check for const after the
    check for ANSI C compiler options, since those may be required
    to make it work properly on HP-UX.
    • 

    
  • add configure test for defining
    _GNU_SOURCE
    • 

    
  • correction to -hold option, ensure that if data is
    already in the output buffer that it will be displayed before
    closing the PTY.
    • 

    
  • move the configure checks for setuid install of xterm into
    a script to avoid installing it setuid'd to a non-root user
    (reported by Adam Sulmicki <adam@cfar.umd.edu>).
    • 

    
  • correct configure script's check for termcap.h to avoid
    using ncurses' version of it on systems that have a working
    tgetent() function. This is needed to make
    resize work properly.
    • 

    
  • fix some typography in ctlseqs.ms description of DEC
    locator events (reported by Stephen P Wall).
    • 
  


  
Patch #117 - 1999/9/29 -
  XFree86 3.9.16b


  
    
    
  • change order of tests in configure script for utmp and
    utmpx to test utmpx first, to compile on Solaris (reported by
    Leena Heino <liinu@uta.fi> and Patrik Hagglund
    <patha@ida.liu.se>).
    • 

    
  • add a configure test for utmp.ut_xtime, needed for SCO
    Openserver, and for lastlog, needed for Redhat 6.0, to refine
    the utmp/utmpx auto-configure.
    • 

    
  • remove a spurious comma in an #undef (reported by David
    Green <greendjf@cvhp152.marconicomms.com> and David
    Ellement <ellement@sdd.hp.com> both on HP-UX, whose
    compiler does care about syntax).
    • 

    
  • change ifdef's using __CYGWIN32__ to __CYGWIN__ (reported
    by Suhaib M. Siddiqi <Ssiddiqi@InspirePharm.Com>, who is
    told that the next Cygnus release will drop that symbol in
    their next release).
    • 

    
  • minor cleanup of ifdef's for makeColorPair (patch by
    Stephen P Wall).
    • 

    
  • work around problem observed in XFree86 3.3.5 (patch by
    Alexander V Lukyanov, Redhat #5419). From the problem report:

      
    
        
    xterm consumes cpu when selecting text with mouse
        (holding down left mouse button) and when a program working
        under the xterm outputs something to stdout.
    

        
    Easy way to reproduce:
    
        while :; do echo aaa; sleep 1; done
    
        (while this runs, select text and hold down left mouse
        button) watch cpu load.
    
        release left mouse button - spinning stops.

Patch #116 - 1999/9/25 -
  XFree86 3.9.16a


  
    
    
  • modify warning if change-ownership of PTY fails; some
    configurations may not happen to have old-style pty's (reported
    by Bob Maynard).
    • 

    
  • improve check in configure script for group ownership of
    installed xterm; some platforms use the -g option of ls to
    toggle group off rather than on (reported by Greg Smith).
    • 

    
  • minor improvement to toolbar geometry, to make it not
    resizable. This still is not satisfactory (but is usable) since
    the toolbar overlaps the xterm widget if the window is resized
    to make it smaller. It appears that some work is needed for the
    xterm widget's geometry management to make it function
    properly.
    • 

    
  • implement configure script tests for utmp, tty group.
    • 

    
  • implement -hold option, allowing users to retain
    the window after a shell has exited (this is recently an FAQ,
    but prompted by a comment by Joachim Plaettner-Hochwarth
    <plaettner@aem.umn.edu> in comp.unix.programmer, that the
    IRIX winterm provides this option).
    • 

    
  • add support for DEC Locator control sequences for xterm
    (integrated patch by Stephen P Wall):
      
                    DECEFR, "Enable Filter Rectangle"
                DECELR, "Enable Locator Reports"
                DECSLE, "Select Locator Events"
                DECRQLP, "Request Locator Position"

    

      
    This allows the xterm mouse to be used with applications
      that use the DEC Locator sequences, such as VAX Tpu, or SMG$
      based applications.
    
    
    • 

    
  • improve print action (patch by Matthias Baake). From his
    notes,

      
      
        
    • Bug 1
      
        Underlined text is preceded by ESC [0;2m . This should
        be ESC [0;4m , ESC [2m doesn't seem to have
        any effect. (print.c/send_SGR)
      • 

        
    • Bug 2
      
        The check for the last non-empty column (while (last >
        0) ... in print.c/printLine) omits the rightmost column of
        the screen, the loop must start with last =
        screen->max_col+1 instead of last =
        screen->max_col.
      • 

        
    • Bug 3
      
        Any attributes of the first character (and of all
        immediately following characters with the same attributes)
        are ignored. The variable attr (print.c/printLine) should
        be initialized with 0, not with *a & SGR_MASK.

Patch #115 - 1999/9/18 -
  XFree86 3.9.16a


  
    
    
  • integrated changes by Stephen P Wall to implement an
    88-color model for systems where 256-colors cannot be
    allocated.
    • 

    
  • when 256-color configuration is compiled, colored bold and
    underlining is not available; ifdef'd to avoid possible odd
    effects in this case (reported by Stephen P Wall).
    • 

    
  • add resource cacheDoublesize, to limit the caching
    of font information for double-sized characters. This addresses
    a problem reported by Aryeh Koenigsberg for X terminals with
    limited font memory.
    • 

    
  • modify treatment of line-drawing characters in UTF-8 mode
    so that the Unicode values are used rather than the C0 codes
    for storing the translated characters (request by Markus
    Kuhn).
    • 
  


  
Patch #114 - 1999/9/15 -
  XFree86 3.9.16


  
    
    
  • add configure script checks for Athena headers and
    libraries under /usr/contrib to work on HPUX (reported by
    several people: David Nixon <djn@csc.liv.ac.uk> Aryeh
    Koenigsberg <aryeh.koenigsberg@telrad.co.il> Johannes
    Mähner <johanm@camline.com> Andrew Gaylard
    <andrew.gaylard@bsw.co.za>).
    • 

    
  • add check to configure script if xterm is installed setgid
    rather than setuid, since wtmp and utmp may be installed with
    group-writable permissions other than root (based on Debian bug
    report #7112 by Bo Branten <bosse@ing.umu.se>).
    • 

    
  • rewrote logic that removes data from termcap entry, e.g.,
    for titeInhibit, to make it less likely to remove the wrong
    data.
    • 

    
  • correct logic which checks for missing characters used for
    line drawing. The 0 character was tested unnecessarily, leading
    to some inefficiency when rendering.
    • 

    
  • change termcap capability which is used as input or output
    of ptyInitialErase logic from kD to kb.
    Christian Weisgerber <naddy@mips.rhein-neckar.de> pointed
    out in effect that kD (in terminfo kdch1)
    should correspond to the control sequence for dch1,
    which deletes from the current position toward the right.
    • 

    
  • check for failure to change ownership of the PTY device and
    warn when xterm is running setuid'd to root. This was reported
    to happen on the FreeBSD/NetBSD/OpenBSD systems as a result of
    the chflags() call.
    • 

    
  • add xterm-noapp terminfo entry to illustate a nominally
    bash-compatible terminal description.
    • 
  


  
Patch #113 - 1999/8/15 -
  XFree86 3.9.15b


  
Several fixes. The main one is a first draft of pulldown
  menus. It's not complete (I have some minor/annoying geometry
  problems to correct), but is usable. Once it's complete I plan to
  add a menu to support additional selections that won't fit on the
  current popup menus. Also, this fits into my longterm plan to
  allow configuring with Motif libraries.


  
    
    
  • correct error in input conversion for NRC mode (reported by
    Stefan Traby <stefan@sime.com>).
    • 

    
  • fix initialization of num_lock data in Misc struct (since
    those fields of the reference widget aren't initialized), and
    add logic to deal with XVision whose NumLock key does not
    transmit but does alter keypad state.
    • 

    
  • correct a missing return-value in get_pty(), for SCO
    • 

    
  • add E2A fix for backspace (patch by Greg Smith), i.e.,
    
    #define VAL_INITIAL_ERASE A2E(127)
    • 

    
  • correct foreground color within cursor outline when the
    window is unfocused (reported by Stephane Chazelas).
    • 

    
  • corrected position of scrollbar set in ResizeScrollBar(),
    which left it positioned incorrectly if the right scrollbar
    were enabled from the popup menu but was not initially enabled.

      
    I have noticed some additional problems with
      right-scrollbar on X11R5 which I will correct later.
    
    
    • 

    
  • integrate changes by Jean-Claude Michot for QNX from
    XFree86 3.3.4c
    • 

    
  • add resources menuBar/MenuBar, menuHeight/MenuHeight for
    later use in toolbar geometry.
    • 

    
  • add configure option --enable-toolbar
    • 

    
  • add missing definition to make ziconbeep logic not
    compile-in when configure script disables it.
    • 

    
  • add configure-check for input-method support in X
    libraries
    • 
  


  
Patch #112 - 1999/7/17 -
  XFree86 3.9Pw


  
    
    
  • add null-pointer check to FlushLog(), fixes a core dump
    when both -l and -lf options are used when xterm is configured
    with wide-character support.
    • 

    
  • remove "ISO" case for SD, which was due to a typographical
    error in ECMA-48 (reported by Paul Williams
    <paul@celigne.co.uk> for vttest).
    • 

    
  • add "FILES" section to manpage.
    • 

    
  • generate header file to initialize default resources for
    colors 16-255.
    • 

    
  • fixes for os390 (Greg Smith):

      
      
        
    • add README.os390
      • 

        
    • use the pty_search() function to find an available
        pty/tty pair.
      • 

        
    • move E2A() call out of getXtermCell() to SaveText()
        function so it will be available in all
        configurations.
      • 
      
    
    
    • 

    
  • patches by Todd Larason:

      
      
        
    • enable SGR 48 5 in ISO color mode, not just 256 color
        mode
      • 

        
    • change configure's --disable-256-color option to
        --enable-256-color, to match its effect
      • 

        
    • fix OSC 4 xx ? (report ansi color) to report a string
        which can actually be used to set the color back
      • 

        
    • fix OSC 4 xx yy (change ansi color) to not allow
        setting colors > 15 in 16 color mode
      • 

        
    • simplify the COLOR_ settings a bit in ptyx.h, along
        with setting NUM_ANSI_COLORS needed for #1 and #4
        above
      • 

        
    • correct string-terminator code passed for reference to
        OSC responses; when in 7-bit mode, only the final byte of
        ST was seen.
      • 

        
    • Allow multiple color #;name pairs in OSC 4, and
        document changes to match.
      • 
      
    
    
    • 
  


  
Patch #111 - 1999/7/10 -
  XFree86 3.9Pw


  
    
    
  • add control sequences for specifying the RGB value of the
    ANSI colors, and for configuring with 256 colors (patch by Todd
    Larason <jtl@molehill.org>). I made the default
    configuration to 16-colors, because xterm uses the default
    color map (which has only 256 colors).
    • 

    
  • correct an error in DCS $ q m reporting for colors 8-15
    (Todd Larason).
    • 

    
  • add test/demo script for double size characters. Used this
    to test/correct display of double size characters that should
    wrap, underlined double size characters.
    • 

    
  • increased cache size for double size fonts to 8, to allow
    for both normal and bold fonts (discussion with Aryeh
    Koenigsberg <aryeh.koenigsberg@telrad.co.il>).
    • 

    
  • add fixes for port to OS390 aka MVS (integrated patch from
    Greg Smith <rys@epaibm.rtpnc.epa.gov>). OS390 uses EBCDIC
    rather than ASCII.
    • 

    
  • correct an off-by-one in binary search limits in
    keysym2ucs.c (Markus Kuhn).
    • 

    
  • implement logging for UTF-8 mode. The output is written in
    UTF-8 form.
    • 
  


  
Patch #110 - 1999/6/29 -
  XFree86 3.9Pu


  
    
    
  • If colorMode is enabled by default, compile-in default
    resources to match the colors listed in XTerm-col.ad (this
    should fix a longstanding FAQ).
    • 

    
  • added new OSC 3 ; PROPNAME=VALUE ST
    escape sequence to set an arbitrary X property on the top level
    xterm X11 window. Omit "=VALUE" to delete the X property (patch
    by Greg Badros <gjb@cs.washington.edu>).
    • 

    
  • change internal flag used for utf8controls
    resource so we allow 31-bit range of characters (suggested by
    Thomas Wolff).
    • 

    
  • add check for 16-bit characters in OSC strings, change them
    to '?' (reported by Thomas Wolff).
    • 

    
  • modify logic of same_font_name() to avoid trying to
    interpret both parameters as wildcard patterns. That does not
    (cannot) work, and in some instances the font server will
    return unresolved wildcards for the normal or bold fontnames,
    making them match inadvertently, triggering the fallback
    overstrike logic (reported by Tim Adye).
    • 
  


  
Patch #109 - 1999/6/23 -
  XFree86 3.9Pt


  
    
    
  • correct range-check from patch #108, which resulted in not
    being able to select from the scrollback buffer (reported by
    Tim Adye <T.J.Adye@rl.ac.uk>)
    • 

    
  • correct "no available ptys" problem with Cygwin B20.1
    (patch by Tim Adye).
    • 

    
  • modified install-ti rule in Makefile.in to allow override
    of the terminfo directory when doing a "make install", i.e., by
    assigning to TERMINFO_DIR (request by Zdenek Sekera
    <zs@sgi.com>).
    • 

    
  • added install-full rule to Makefile.in
    • 

    
  • resync mkdirs.sh and install.sh scripts against current
    autoconf
    • 

    
  • implement $(DESTDIR) in Makefile.in, making it simple to
    install xterm and associated files into a directory just for
    packaging a binary release (suggested by CaT
    <cat@zip.com.au>).
    • 

    
  • change IChar type to unsigned, rather than unsigned short,
    making room for a flag to keep with 16-bit characters to
    prevent them from being interpreted as C0 or C1 controls
    (reported by Thomas Wolff).
    • 

    
  • correct a typo from patch #107, incorrect array name, in
    the filterUTF8 function (patch by Bruno Haible
    <haible@ilog.fr>)
    • 

    
  • add utf8controls resource to specify whether xterm
    should interpret 16-bit characters unpacked from UTF-8 form as
    control characters if they happen to fall into that range. This
    behavior is left unspecified by the Unicode standard (request
    by Thomas Wolff).
    • 

    
  • modify handling of OSC to recover if application sends
    16-bit characters with codes above 255. We cannot display them
    as is, but translate out-of-range characters to a '?' (reported
    by Thomas Wolff).
    • 
  


  
Patch #108 - 1999/6/19 -
  XFree86 3.9Ps


  
    
    
  • add a range-check to LastTextCol(), to guard against
    indexing before the beginning of the scrollback buffer. This
    appears to happen with certain fonts under X11R5 (reported by
    Stephane Chazelas <Stephane_Chazelas@Raytheon.com>).
    • 

    
  • implement resource boldMode, to allow disabling
    the simulation of bold fonts when the bold and normal fonts are
    not different (requested by Will Day
    <willday@rom.oit.gatech.edu>).
    • 

    
  • change the atom "UTF-8" to "UTF8_STRING", and fixes a few
    bugs in the UTF-8 selection (patch by Juliusz Chroboczek).
    • 

    
  • correct logic of binary-search in keysym2ucs.c (patch by
    Markus Kuhn).
    • 

    
  • add special interpretation of keysym codes above 0x1000000
    as the corresponding UCS value plus 0x1000000 (patch by Markus
    Kuhn).
    • 
  


  
Patch #107 - 1999/6/12 -
  XFree86 3.9Pq


  
    
    
  • Two changes from Stephen P Wall. From his description:

      
    
        
    The first change is simple - I added ESC[3J to erase the
        stored lines above the screen. That's what the changes to
        util.c and ctlseqs.ms are.
    

        
    The second change is to get the blinking cursor working.
        I took out the cursorBlinkTime resource, and put in
        cursorBlink (Boolean), cursorOnTime (time cursor is on in
        msecs) and cursorOffTime, and added a cursorblink item to
        the vtMenu to enable/disable it.
    
      
    
    
    • 

    
  • improve selection (integrated patch by Juliusz Chroboczek).
    From his description:

      
    
        
    With this patch, selection conversion works
        properly:
    
        
            ISO 8859-1 xterm -> ISO 8859-1 xterm (transferred as STRING);
        ISO 8859-1 xterm -> UTF-8 xterm (transferred as STRING);
        UTF-8 xterm -> ISO 8859-1 xterm (transferred as STRING);
        UTF-8 xterm -> UTF-8 xterm (transferred as UTF-8).

    

        
    It will not work properly if one xterm is in, say, ISO
        8859-2. Actually, for this case xterm breaks the ICCCM
        routinely (sending ISO 8859-2 data as STRING), so I
        wouldn't worry too much about it. I have not changed the
        behaviour in eight-bit mode in any way.
    
      
    
    
    • 
  


  
Patch #106 - 1999/6/9 -
  XFree86 3.9Pq


  
    
    
  • remove duplicate fix for OpenBSD in resize.c
    • 

    
  • correct logic in ScreenWrite, which did not reset the high
    bytes of 16-bit characters when overwriting them with a 8-bit
    character string (reported by Thomas Wolff).
    • 

    
  • provide limited support for input of UTF-8 16-bit data by a
    lookup table (integrated patch by Markus Kuhn).
    • 

    
  • correct check in non_blank_line to ensure we're in
    wide-character mode before looking at the high bytes, for
    InsertChar.
    • 
  


  
Patch #105 - 1999/6/5 -
  XFree86 3.9Pp


  
    
    
  • implement new resource trimSelection, which allows
    xterm to trim trailing blanks from selected lines. This does
    not affect the highlighting. (reported by several people using
    mutt, including Hans Morten Kind <edphk@uib.no>,
    Jeremy <jeremy@exit109.com> and (Michael Fuller
    <msf@mds.rmit.edu.au>).
    • 

    
  • include term.h in resize for OpenBSD (patch by Matthieu
    Herrb).
    • 

    
  • correct logic for UTF-8 in functions that hide and show the
    cursor; it was displaying a space whenever the low byte of the
    character at the cursor position was zero (reported by Thomas
    Wolff <Thomas.Wolff@icn.siemens.de>).
    • 
  


  
Patch #104 - 1999/5/30 -
  XFree86 3.9Pn


  
This is a resync patch against XFree86 3.9Pn, reflecting
  changes which were submitted by Branden Robinson, who worked with
  Wichert Akkerman <wichert@cs.leidenuniv.nl> to set up
  ifdef's to handle GNU libc 2.1, and use getpt() which lets xterm
  avoid having to know the actual PTY name.


  
I have also added a few fixes for signed/unsigned mismatches,
  and corrected a problem in the configure script (the UTF-8 code
  was always configured since the Imakefile defines this).


  
Patch #103 - 1999/5/14 -
  XFree86 3.9Pm


  
    
    
  • correct selection logic: I omitted an offset that accounts
    for the distance into the scrollback buffer when rewriting this
    for patch #101. Also fixed a similar problem for selecting
    double size characters from the scrollback buffer (first was
    reported by D Roland Walker <walker@pobox.com>).
    • 

    
  • improved support for Unix98 PTY's, using patch in Debian
    bug report #35650, by J.H.M. Dassen
    <jdassen@wi.leidenuniv.nl>. From the patch description:

      
    
        
      
          
    • No longer links xterm against libutil on a glibc2.1
          system. libutil is a compatibility library and should
          only be used when necessary. Rather than having get_pty()
          use openpty() from this compatibility library, use the
          real UNIX98 pty support in get_pty() (open()ing the
          master pty, through getpt() if available (glibc
          extension)). Use openpty() only under glibc2.0.
      • 

          
    • GNU libc2 is not Linux-specific; already it runs on
          the Hurd. It provides the UNIX98 pty functions (plus the
          getpt() extension), regardless of the underlying OS.
          Changed two constructs to look for GNU libc2 only, not
          GNU libc2 on Linux.
      • 
        
    
      
    
    
    • 

    
  • improve font configuration, by checking if the user's
    resource settings for normal and bold fonts give the same font
    sizes (fixes problem reported by Peter Waltenberg
    <peterw@dascom.com>).
    • 
  


  
Patch #102 - 1999/5/12 -
  XFree86 3.9Pm


  
    
    
  • revert change to openpty call in patch #101; this causes
    xterm to fail on DEC-Alpha OSF/1 4.0B (reported by H Merijn
    Brand).
    • 

    
  • modify print.c to move include of stdio.h after the
    autoconf'd xtermcfg.h since HP's ANSI C compiler otherwise sees
    inconsistent prototype for getopt, probably due to problem with
    const (reported by H Merijn Brand).
    • 
  


  
Patch #101 - 1999/5/10 -
  XFree86 3.9Pm


  
    
    
  • moved includes and definitions for 'select' from data.h to
    xterm.h to fix problem introduced by prototype for getPtyData,
    part of UTF-8 changes (reported by Jens Schleusener
    <Jens.Schleusener@dlr.de>)
    • 

    
  • added "Meta <Btn2Down>:clear-saved-lines()" default
    translation (patch by H Merijn Brand)
    • 

    
  • fixes to configure script and ifdef's in main.c to build on
    a HP9000/D390 (hppa-2.0w) running HP-UX 11.00 (64 bit) with
    egcs 1.1.2 and HP's ANSI C compiler (patch by H Merijn Brand

  • add more parentheses in ifdef's (patch by Bob
    Maynard).
    • 

    
  • eliminate conflicting definitions for USE_TERMINFO in
    resize.c (reported by Jeremy Buhler).
    • 

    
  • change openpty call to pass NULL rather than ttydev
    parameter, since that was used only to estimate the length of
    the corresponding data, and may not really be long enough
    (reported by Andreas Jaeger)
    • 

    
  • update description in xterm manpage for character class
    table, which said it handles only 7-bit codes.
    • 

    
  • correct a typo in ScrnDeleteChar() which made it not clear
    the high byte of wide-character data.
    • 

    
  • add logic to convert selection to UTF-8 form when
    appropriate. This makes select/paste "work", but further work
    is needed to make UTF-8 recognized as a locale in Xlib.
    • 

    
  • correct right-limit check when selecting double-width
    characters.
    • 

    
  • change default answerback response to an empty string.

Patch #100 - 1999/5/3 -
  XFree86 3.9Pl


  
    
    
  • Correct a typo in the default resource value for
    backarrowKeyIsErase: it was always true (reported by Bram
    Moolenaar).
    • 

    
  • improve configure script's test if the installed xterm is
    setuid, in case that is a symbolic link.
    • 

    
  • correct "install-ti" rule in Makefile.in, by not setting a
    blank $TERMINFO value. That is interpreted as "." by ncurses'
    tic.
    • 
  


  
Patch #99 - 1999/5/2 -
  XFree86 3.9Pk


  
    
    
  • correct logic that computes num_ptrs count of the number of
    indices into the screen buffer. This is the maximum of the
    colors and character-set indices; was incorrect in patch
    #97.
    • 

    
  • correct argument type for sigsetjmp, incidental change in
    patch #96's Unix88 PTY patch (reported by Bram Moolenaar).
    • 

    
  • correct description of secondary DA in ctlseqs.ms (reported
    by Bram Moolenaar).
    • 

    
  • decouple the backarrowKey and ptyInitialErase resources by
    adding a new resource backarrowKeyIsErase, to accommodate
    people using applications which have hardcoded tests for
    characters 8 and 127 rather than relying on the stty
    settings.
    • 

    
  • modify the UTF-8 decoder so that all possible illegal UTF-8
    sequences are properly represented by U+FFFD. This should be
    very helpful for developers of code that output UTF-8 strings
    for debugging. See the file utf-8-test.txt in
    http://www.cl.cam.ac.uk/~mgk25/download/ucs-fonts.tar.gz for a
    demonstration text that contains numerous illegal UTF-8 values.
    (patch by Markus Kuhn).
    • 

    
  • correct a place in ScrnRefresh where I was filling the high
    byte of a wide character with a space rather than a null
    (reported by Markus Kuhn).
    • 
  


  
Patch #98 - 1999/4/26 -
  XFree86 3.9Pk


  
    
    
  • correct data manipulation in unparseputc(), broken for
    little-endian machines by patch #97's UTF-8 changes. This meant
    that keyboard input on SunOS did not work, though Linux i386
    was fine.
    • 

    
  • modify initialization for backarrowKey and logic for
    initial-erase to prevent the initial-erase from overriding an
    explicitly set backarrowKey resource (reported by Vikas
    Agnihotri).
    • 

    
  • add a missing null-pointer check in ScrnRefresh, for the
    wide-characters configuration.
    • 
  


  
Patch #97 - 1999/4/25 -
  XFree86 3.9Pk


  
    
    
  • add configure script test for -lutil, needed for openpty
    call when configuring xterm for Glibc-2.1 and Unix98 PTY's
    (first reported by Martin Lorentz"
    <m.lorentz@w12.link-goe.de>).
    • 

    
  • completely parenthesize ifdef expressions for Glibc
    (suggested by Bob Maynard).
    • 

    
  • add initial-erase options (-ie, +ie) to help message
    (reported by Vikas Agnihotri).
    • 

    
  • remove duplicate definition of USE_USG_PTYS (reported by
    Jeremy Buhler).
    • 

    
  • change termcap kD and terminfo kdch1 to a
    DEL (\177). I overlooked this when separating the styles of
    keyboard with the sunKeyboard resources in patch #94,
    so that it normally matches the value of the stty erase
    character:

      
      
        
    • Reported by Jae Gangemi
        <jgangemi@ccf.rutgers.edu>, this caused emacs to not
        process the DEL properly, combining it with succeeding
        characters.
      • 

        
    • This does not appear to be related to a problem which I
        have found with screen, which translates the stty
        erase into the termcap kD or terminfo
        kdch1 value (depending on how it is linked) if the
        $TERMCAP variable is set when screen is
        invoked.
      • 
      
    
    
    • 

    
  • add command-line options for enabling UTF-8 mode: -u8 and
    +u8. The more obvious -utf8 and +utf8 would conflict with
    xterm's -ut and +ut (utmp) options. The UTF-8 changes were
    requested by Markus Kuhn <Markus.Kuhn@cl.cam.ac.uk>. This
    patch does not complete UTF-8 implementation, but makes it
    usable, i.e., display and refresh work, and I am able to
    display the test cases which Markus provides. More work is
    needed to complete this feature:

      
      
        
    • the control sequences for switching in/out of UTF-8
        mode are partly implemented (don't use them). Similarly,
        the switching between vt100 and tek4014 emulations when
        UTF-8 mode is enabled will not work properly.

          
      You must use the -u8 command line option to use this
          feature, as well as compile with the OPT_WIDE_CHARS
          definition.
      
        
      • 

        
    • cut/paste only copies 8-bit characters.
      • 

        
    • logging is disabled in the wide-character
        configuration
      • 

        
    • printing only writes 8-bit characters.
      • 

        
    • input only does 8-bit characters. This is the area that
        I know least about.

Patch #96 - 1999/4/19 -
  XFree86 3.9Pj


  
    
    
  • modify Makefile.in to work with configure script's --srcdir
    option. (patch by Jeremy Buhler
    <jbuhler@cs.washington.edu>)
    • 

    
  • add checks for 'echo -n' equivalent for 8colors.sh and
    16colors.sh scripts (reported by Vikas Agnihotri).
    • 

    
  • improve logic that looks for bold fonts to allow for
    wildcards in the specification for normal fonts, and to ensure
    that if a bold font is specified as normal, that xterm will
    simulate a bold version of that using a one-pixel offset
    overstrike (reported by Henrik Harmsen
    <harmsen@erv.ericsson.se>).
    • 

    
  • correct horizontal spacing of double width line-drawing
    characters that xterm simulates.
    • 

    
  • improve support for Unix98 PTY's, using patch in Debian bug
    report #35650, by Topi Miettinen
    <Topi.Miettinen@medialab.sonera.fi>. Andreas Jaeger says
    this also corrects a permissions problem reported by
    cat@zip.net.au
    • 

    
  • modify initial-erase logic to ensure that
    ttyModes resource overrides it.
    • 
  


  
Patch #95 - 1999/4/5 -
  XFree86 3.9Ph


  
    
    
  • modify primary DA response to allow a '1' parameter.
    • 

    
  • add printer and national replacement character sets to
    VT220 primary DA response.
    • 

    
  • document primary and secondary DA responses in
    ctlseqs.ms
    • 

    
  • use the patch number (e.g., 95) in the secondary DA
    response, providing user applications a means of determining
    the version of xterm for feature comparison (request by Bram
    Moolenaar).
    • 

    
  • make xterm respond to secondary DA when the decTerminalID
    is set for VT100.
    • 

    
  • limit user-defined keys (DECUDK) to VT220-style keyboard
    when sunKeyBoard resource is true.
    • 

    
  • modify ifdef's for Linux-2.2.x with Glibc-2.1 to work with
    Glibc-2.1 and no Unix98 PTY support (patch from Andreas Jaeger
    <aj@arthur.rhein-neckar.de>)
    • 

    
  • add optional feature (resource and command-line options) to
    make xterm use the PTY's sense of erase character on startup,
    rather than requiring it to be \177, or set the PTY's erase
    character to match xterm's configuration. Note that while
    $TERMCAP is modified to reflect the actual configuration, the
    terminfo kdch1 string is not (request by Dirk H Hohndel
    <hohndel@suse.de>)
    • 

    
  • improve scripts in vttests to work with newer shells that
    do not use 'echo -n'.
    • 

    
  • add fonts.sh example script
    • 

    
  • correct inequality in handling of "#1" font
    specification.
    • 

    
  • correct call to XGetWMNormalHints() used for computing
    maximum screen size; the size hints may not have been set.
    • 

    
  • begin implementation of support for wide-characters
    (configure option --enable-wide-chars defines OPT_WIDE_CHARS,
    invoke xterm with -wc option to activate this feature). This
    patch optionally widens internal data structures, invokes the
    16-bit text output rather than the 8-bit version and adds some
    tables.
    • 
  


  
Patch #94 - 1999/3/27 -
  XFree86 3.9Pf


  
    
    
  • further fixes for terminfo: ka1, ka3, etc., differ between
    the default xterm-xfree86 and xterm-vt220 entries.
    • 

    
  • change default (with sunKeyboard resource false) behavior
    of the editing keypad "Delete" to send a 127, like xterm-r6.
    The VT220-style <ESC>[3~ is sent when
    sunKeyboard is true (reported by Tomas Vanhala).
    • 

    
  • add parameters to function keys to indicate if shift,
    control or alt are set. The codes are based on a description of
    a DEC VT510 with a PC keyboard, from Jeffrey Altman
    <jaltman@watsun.cc.columbia.edu>.
    • 

    
  • add control sequence 1035, set-num-lock action and num-lock
    menu entry to control the use of the NumLock and Alt keys for
    the Sun/PC and VT220 keyboard extensions.
    • 

    
  • implement DECSET/DECRST numeric keypad (DECNKM) mode.
    • 

    
  • modify terminfo and termcap to use recommended "X Window"
    or "X11" names rather than "X Windows" (reported by Tomas
    Vanhala).
    • 

    
  • suppress translation of shifted keypad "+" when sunKeyboard
    is true.
    • 

    
  • workaround unexpected behavior (perhaps bug) in
    XmbLookupString, which returns trash in the string buffer for
    numlock and control-key combined with keypad-keys.
    • 

    
  • modify ScrollBarReverseVideo() to keep scrollbar border
    visible when reverse video is toggled.
    • 

    
  • correct missing case for parameter 17 (set highlight color)
    in dynamic colors control sequences.
    • 

    
  • extend dynamic colors control sequences to allow users to
    determine the colors and font which are currently active.
    • 

    
  • minor tweak to OSC responses, to use BEL if the application
    used that to end the request, rather than ST. This works better
    with shell scripts, which may not handle an
    <ESC>backslash very well.
    • 

    
  • separate menu settings for reverse video from that done
    under program control.
    • 

    
  • corrected ifdef's for menus, which did not allow tek4014 to
    be suppressed properly (reported by Clint Olsen).
    • 

    
  • changes for Linux-2.2.x with GLibc-2.1 and /dev/ptmx
    support (integrated patch from Pavel Roskin):

      
      
        
    • main.c and resize.c were using different rules to
        determine whether ATT should be defined (actually
        USE_USG_PTYS is more apt).
      • 

        
    • copy definitions from main.c to resize.c to prevent
        sys/stream.h and sys/ptem.h from inclusion when SYSV is not
        defined
      • 

        
    • define CNUL if not already defined like other
        variables.
      • 

        
    • /dev/tty does exist in Linux, but it doesn't mean, it
        should be used. Therefore EACCES is now an acceptable
        result.
      • 

        
    • ifdef'd several calls such as ioctl (ptyfd,
        I_PUSH, "ptem") to build on Linux (I_PUSH is not
        defined when sys/stropts.h is not included).
      • 
      
    
    
    • 

    
  • initialize second "ltc" variable in main.c (reported by
    David Dawes).
    • 

    
  • provide definition for USE_USG_PTYS in screen.c
    • 

    
  • add resource-files to install rule in standalone
    Makefile.in
    • 

    
  • add sample scripts to illustrate titlebar controls,
    resizing and colors.
    • 
  


  
Patch #93 - 1999/3/14 -
  XFree86 3.9Pd


  
Here are several fixes and minor enhancements. The chief ones
  are the fixes for NumLock mode and reverse video, since we had
  become used to working around the problems.


  
    
    
  • remove kfnd/kll/kslt strings from terminfo, because curses
    applications do not necessarily return khome/kend pairs
    (reported by Vikas Agnihotri).
    • 

    
  • implement NumLock resource which overrides the keyboard
    tables for the special case of keypad keys. This is a problem
    introduced in xterm by X11R6 changes, i.e., an ambiguity which
    in effect discarded vt100 keypad support.
    • 

    
  • modify Sun/PC keyboard mode to extend this (emulation of
    DEC vt100 keypad) to the remainder of the numeric keypad. Now,
    the default operating mode of xterm uses the keyboard tables
    as-is (except if the NumLock mode overrides), but provides good
    vt100 keypad compatibility if the Sun/PC keyboard menu item is
    checked.
    • 

    
  • separate command-line settings for reverse video from that
    done under program control. This is a problem which was
    introduced by X11R6. Though correct, most users are
    confused by allowing the reset command to undo the effect of
    the command-line -rv option.
    • 

    
  • add description of function keys, keypad and cursor keys to
    ctlseqs.ms
    • 

    
  • add terminfo entries for xterm-vt52, xterm-sun and
    xterm-hp
    • 

    
  • correct typo (missing case value) for DECSET 35,
    enable/disable shifted keypad action and a few compiler
    warnings (reported by Zdenek Sekera <zs@sgi.com>).
    • 

    
  • correct reporting of color values 8-15 in DECRQSS (reported
    by Vikas Agnihotri).
    • 

    
  • modify parsing of ttyModes resource to recognize "^-" as
    "undef" (requested by Tomas Vanhala).
    • 

    
  • integrate/extend changes to add iconify/maximize actions
    (from Edward S. Arthur <eda@ultranet.com>).
    • 

    
  • add control sequences for maximizing/restoring window, and
    for reporting maximum screen size.
    • 

    
  • add 'interpret' action, to support local function-key
    interpretation. Used properly, this makes most of the
    specialized actions of xterm redundant.
    • 

    
  • add control sequence private modes 1051, 1052 and 1052, for
    setting the Sun and HP function key modes, and for setting the
    Sun/PC keyboard mode.
    • 

    
  • add configure option --disable-maximize
    • 

    
  • add configure option --disable-num-lcok
    • 

    
  • extend descriptions of configure script options in
    INSTALL.
    • 
  


  
Patch #92 - 1999/2/5 -
  XFree86 3.9Nz


  
    
    
  • increase buffer size for tgetent (i.e., termcap) to 1500.
    This fixes a problem where screen is built using
    ncurses or GNU termcap and xterm is built using the
    standard termcap interface. The former does not limit the
    termcap size, while the latter is assumed to be no longer than
    1023 characters. The screen program's termcap entry is
    about 1200 characters long.
    • 

    
  • change update_menu_item() to a function, to simplify
    debugging. This also reduces the executable by 4Kb.
    • 

    
  • add control sequences for DECSET 30, 1010, 1011 like rxvt
    (enable or disable some features that were only settable via
    resources or command line arguments).
    • 

    
  • add control sequence for DECSET 35, which enables/disables
    the shifted keypad functions.
    • 

    
  • add support for switching font sizes, by stepping through
    the font menu using shifted keypad plus and minus.
    • 

    
  • correct missing initialization of tekInhibit and tekSmall
    resources.
    • 

    
  • correct ifdef's in charproc.c for XtNgeometry and
    XtCGeometry (reported by Bram Moolenaar).
    • 
  


  
Patch #91 - 1999/1/21 -
  XFree86 3.9Nw


  
    
    
  • Implement logic to translate input characters which are
    mapped when in vt220 National Replacement Character mode
    (requested by Tomas Vanhala).
    • 

    
  • Resync configure scripts with my patches to autoconf
    2.13
    • 

    
  • Change order of -lXmu and -lXext to accommodate cygwin32
    (reported by Vikas Agnihotri).
    • 

    
  • Add "-ti" option to set terminal emulation level from
    command line rather than via resource.
    • 

    
  • Simplify some of the preprocessor logic using #elif.
    • 
  


  
Patch #90 - 1998/12/13 -
  XFree86 3.9Nq


  
This implements several small fixes and enhancements. The
  chief one implements fallback support for line drawing characters
  with fonts that do not include those characters. But I
  implemented that last.


  
    
    
  • If any of the glyphs in positions 0-31 (used by xterm to
    implement the VT100 alternate character set) are zero-sized
    (i.e., missing), xterm will reserve a normal space for the
    glyph when drawing. I implemented a simple stroke-drawing
    function to draw the line-drawing characters and a couple of
    the other (simpler) characters such as diamond. (This was
    suggested by Vikas Agnihotri).
    • 

    
  • Modify the computation of doublesize characters to work
    around font servers which shift the scaled characters up/down
    or do not give the correct width.
    • 

    
  • Add popup menu item and corresponding resource settings to
    disable the font-scaling logic for doublesize characters to
    work around (older) font servers which simply do not draw the
    fonts scaled to the size that they said they would. I see this
    problem on a SunOS system running X11R5; the X11R6 servers seem
    well behaved.
    • 

    
  • Implement new escape sequence, private mode 1049, which
    combines the switch to/from alternate screen mode with screen
    clearing and cursor save/restore. Unlike the existing escape
    sequence, this clears the alternate screen when switching to it
    rather than when switching to the normal screen, thus retaining
    the alternate screen contents for select/paste operations.

      
    When I implemented the popup menu entry to toggle between
      the normal and alternate screens, I considered only pasting
      from the normal screen to the alternate; this improvement
      allows either direction.
    
    
    • 

    
  • Changed the termcap and terminfo for xterm-xfree86 and
    xterm-8bit to use the new 1049 private mode.
    • 

    
  • Modify the logic which switches between normal and
    alternate screens so that the save/restore cursor operations
    apply only to the current screen. That means that applications
    which use the terminfo smcur/rmcur or termcap ti/te
    capabilities will restore the cursor to the original position
    on the normal screen rather than to the most recent place where
    a save-cursor operation was performed.

      
    I note that a real VT100 terminal would not behave in this
      way, but it is a moot point since the VT100 does not
      implement alternate screen, and therefore the save/restore
      cursor sequence would not be used in this context. I reviewed
      the logic which switches between normal and alternate screens
      based on some recent newsgroup postings as well as a proposed
      patch in the Debian group which attempts to do this (the
      patch has a bug, however, so I did not use it).
    
    
    • 

    
  • Add popup menu entry for toggling the titeInhibit
    resource.
    • 

    
  • Add new resource answerbackString, which overrides the
    default "xterm" returned by xterm when responding to an ENQ
    (control/E) character (request by Rajesh Vaidheeswarran
    <rv@fore.com>).
    • 

    
  • Add new resource keyboardDialect for setting the NRC
    display character set (request by Tomas Vanhala, who notes that
    I should add logic to translate the keyboard as well).
    • 

    
  • Add new command-line option and corresponding resources for
    making xterm generate escape sequences compatible with HP
    terminals. Like the existing Sun escape sequences, this is
    available as a popup menu item. It is enabled by the configure
    script with the option --enable-hp-fkeys (requested by Toni
    Mueller <sales@oeko.net>).
    • 

    
  • Add configure script option --disable-boxchars to disable
    the fallback support for line drawing characters.
    • 

    
  • Fix ifdef's for configure script --disable-ansi-color, and
    reviewed all configure options to ensure that all can be
    enabled/disabled appropriately.
    • 

    
  • Update config.guess and config.sub, from Lynx.
    • 
  


  
Patch #89 - 1998/11/20 -
  XFree86 3.9Nm


  
This patch completes the implementation of double-sized
  character support for the VT100 emulation, and fixes a few minor
  bugs:


  
    
    
  • corrected the cursor position in HideCursor, which did not
    multiply the column by two when in doublesize mode. This bug,
    which did not appear in normal use, dates back to my original
    changes to partly implement
    double-sized characters. I noticed it when cat'ing a typescript
    from vttest's double-sized character test.
    • 

    
  • ensure that the current line is repainted when switching
    between single and double width characters.
    • 

    
  • reduce the number of bits used for double-sized character
    coding from 3 to 2, to make more room for soft-font codes.
    • 

    
  • copy newer ifdef's from the XFree86 3.3.3 release's main.c,
    which address details of glibc and powerpc.
    • 

    
  • moved definition of DECL_ERRNO in xterm.h to match XFree86
    3.3.3
    • 

    
  • modify resize to remove the ifdef on SVr4 that
    suppressed printing the script for $LINES and $COLUMNS.
    Solaris' resize utility does this; suppressing the behavior is
    unnecessary.
    • 
  


  
I tested the double-sized characters using vttest and the
  xfsft patch. These fonts worked reasonably well:

  
        -bitstream-courier-medium-r-normal--0-0-0-0-m-0-iso8859-1
        9x15



  
The iso8859 font does not include box characters, of course,
  but looks good.


  
Patch #88 - 1998/10/31 -
  XFree86 3.9Nk and 3.3.2h


  
This refines my #85 patch by checking for a case where the
  font server returns a bold font that does not quite correspond to
  the normal font. When I asked for a bold version of the 6x12
  font, the font server returned a near equivalent where the ascent
  and descent values did not match, causing xterm to leave lines
  across the display. This patch makes xterm reject that type of
  mismatch, falling back to the old font behavior.


  
Patch #87 - 1998/10/21 -
  XFree86 3.9Nj and 3.3.2f


  
This corrects a problem reported by Stefan Dalibor. My table
  entries for the printerExtent and
  printerFormFeed resources used the wrong types for
  sizeof, causing the printer to not work properly on some
  platforms because the printAttributes resource was
  overwritten (e.g., Digital Unix with DEC Alpha).


  
I reviewed all of the resource table entries and fixed a
  potential problem with resizeGravity, which was typed as
  int rather than XtGravity.


  
Patch #86 - 1998/10/14 -
  XFree86 3.9Nj and 3.3.2e


  
A small fix: when switching to/from the continuous mouse
  reporting mode, the event mask was incorrect if xterm was built
  under X11R5 because the original data was saved under an ifdef
  for active-icon.


  
Patch #85 - 1998/10/12 -
  XFree86 3.9Nj and 3.3.2e


  
Some cleanup (I noticed the pixel droppings a few months ago
  after getting a new 17" monitor):


  
    
    
  • split-out the functions that load/reload fonts for xterm as
    new file fontutils.c to extend them to support automatic
    loading of bold font corresponding to the normal font. Adapted
    logic from EMU 1.3 for this purpose. This fixes most
    occurrences of pixel droppings from bold characters.
    • 

    
  • modified by renaming variables and adding casts to permit
    compile with g++.
    • 

    
  • modify headers so they can all be compiled without order
    dependencies, and use bracketed rather than quoting includes to
    allow compile from separate directory.
    • 

    
  • renamed xtermm terminfo entry to xterm-mono, to avoid
    conflict with Solaris entry now in ncurses.
    • 
  


  
Patch #84 - 1998/10/9 -
  XFree86 3.9Ni and 3.3.2e


  
Several small fixes and enhancements, including a patch from
  Bjorn Helgaas:


  
    
    
  • correct initialization of TERMCAP environment variable,
    which was frequently set to garbage on non-Linux systems
    because "termcap" and "newtc" contained random data from the
    stack.
    • 

    
  • remove the LINEWRAPPED attribute from lines as they are
    cleared. Previously, the attribute was set but never
    cleared.
    • 

    
  • make word and line selections work even when lines are
    wrapped by xterm. Previously, selections were limited to one
    screen line.
    • 
  


  
as well as


  
    
    
  • modify logic for line-wrapping to reset the associated flag
    if the application deletes a character. This fixes a problem
    reported by Bjorn Helgaas where word/line selection would still
    wrap even after deleting characters from the first line.
    • 

    
  • add kll/kH capabilities to xterm-xfree86 entries in termcap
    and terminfo (request by Michael Schroeder).
    • 

    
  • shorten descriptions in termcap to make resolved entries
    all shorter than 1023 character limit.
    • 

    
  • use DECSTR control sequence to shorten initialization and
    reset strings in xterm-xfree86 termcap and terminfo.
    • 

    
  • use rmul/smul and rmir/smir in xterm-r5 terminfo to match
    termcap.
    • 

    
  • correct typos in initialization and reset strings in
    xterm-r5 termcap and terminfo.
    • 

    
  • disable special translations of key symbols (the backarrow
    key, the editing keypad and the keypad "+") when a modifier
    other than shift, control or numlock is used. This makes xterm
    handle the meta key as expected by people using emacs (reported
    by Pete Harlan <harlan@pointofchoice.com> in
    linux.debian.user newsgroup).
    • 
  


  
Resync #83 - 1998/10/7 -
  XFree86 3.3.2e


  
Merge changes through patch #83 with the 3.3.2e version.


  
This follows a change from XFree86 CVS which adds checks for
  non-null return from malloc (patch by Matthieu Herrb).


  
Patch #83 - 1998/8/25 -
  XFree86 3.9Nb


  
Several small fixes and enhancements:


  
    
    
  • add configure test to infer if xterm should be installed
    setuid based on previously installed xterm (reported by Stephen
    Marley and Stefan Dalibor).
    • 

    
  • implement quasi-continuous mouse reporting (integrated
    patch by Jason Bacon).
    • 

    
  • correct control sequences transmitted by function keys F1
    to F4 when sunFunctionKeys resource is true (it was still using
    the VT100 control sequences).
    • 

    
  • modify handling of backarrow key so that the control
    modifier toggles the backspace/delete interpretation set by the
    backarrowKey resource.
    • 

    
  • limit the row and column values used to report mouse
    position.
    • 
  


  
From resync with XFree86 3.9Nb:


  
    
    
  • add support for the VSTATUS control character (patch by
    Robert Earl <rearl@teleport.com>).
    • 
  


  
Patch #82 - 1998/7/15 -
  XFree86 3.9Aj


  
Bug fix for patch #81:


  
    
    
  • remove an #undef for NBBY, which caused compile problem on
    FreeBSD (reported by David Dawes).
    • 
  


  
Patch #81 - 1998/7/14 -
  XFree86 3.9Aj


  
More bug fixes:


  
    
    
  • fix conflicting ifdef's for TIOCSLTC when building with
    Linux on AXP aka DEC Alpha (reported by Robin Cutshaw).
    • 

    
  • correction to patch #79, move assignment for
    *utptr->ut_user = 0; back into non-SVR4 ifdef in main.c,
    since this clobbers username on Solaris 2.5.1 (analysis by Will
    Day <willday@rom.oit.gatech.edu>).
    • 

    
  • corrected khome/kend in xterm-8bit terminfo
    description.
    • 

    
  • improve cursor color by making it always the reverse of
    fg/bg unless the cursorColor resource is set, i.e., to
    something other than the default foreground (reported by Vikas
    Agnihotri and Bram Moolenaar).
    • 

    
  • minor fixes for compiler warnings, including a syntax error
    in the AMOEBA ifdef's.
    • 
  


  
From resync with XFree86 3.9Aj:


  
    
    
  • correction to patch #73, supply missing #else for fallback
    definitions of size_t, time_t (Robin Cutshaw
    <robin@intercore.com>).
    • 
  


  
Patch #80 - 1998/6/29 -
  XFree86 3.9Ai


  
This fixes a couple of items leftover or introduced by patch
  79:


  
    
    
  • take out the logic that suppresses editing-keypad in vt100
    mode (those keys are too valuable to give up for a fine point
    of emulation).
    • 

    
  • corrected a couple of places in terminfo where I missed
    using the vt220-style editing-keypad codes for Find/Select
    (mapped to Home/End).
    • 

    
  • checked termcap file against terminfo, fix several places
    where it was inconsistent.
    • 
  


  
Patch #79 - 1998/6/28 -
  XFree86 3.9Ai


  
This patch fixes several small bugs:


  
    
    
  • use X_EXTRA_LIBS in standalone Makefile.in (patch by Tomas
    Vanhala).
    • 

    
  • add new resource 'oldXtermFKeys' which provides backward
    compatibility for F1-F4 control sequences with TOG's
    xterm.
    • 

    
  • determine the server's default foreground/background Pixel
    values, needed if the -flipPixels X server option is used
    (reported by David Dawes).
    • 

    
  • correct logic for F1-F4 function keys so that they generate
    VT100 compatible escape sequences in VT220 mode, since that is
    what the numeric keypad is supposed to do (reported by Ron
    Johnson, Jr. <ronjohn@communique.net>).
    • 

    
  • modify logic for editing keypad to work more like VT220:
    don't pass those codes in VT100-mode unless oldXtermFKeys mode
    is set.
    • 

    
  • correct an interaction with the editing-keypad logic that
    prevented backarrow key from sending a 127 for the delete key
    (the 'remove' escape sequence was being sent instead).
    • 

    
  • use return-value from getuid() rather than the parameter,
    to work on systems which do not update the latter (patch by
    Kevin Buhr <buhr@mozart.stat.wisc.edu>)
    • 

    
  • correct scrollbar border color when toggling to/from secure
    keyboard mode (patch by Jeff Uphoff
    <juphoff@tarsier.cv.nrao.edu>)
    • 

    
  • modifications to terminfo file:

      
      
        
    • rename description to xterm-xfree86, adding an entry
        'xterm' which is derived from xterm-xfree86 to simplify
        customization.
      • 

        
    • change string for kdch1 from \177 to \E[3~, to address
        complaints from Debian developers. (This applies to the key
        labeled "Delete", and does not affect the backarrow
        key).
      • 

        
    • add user-strings u6, u7, u8, u9 to entries to make them
        work with Daniel Weaver's "tack" program.
      • 

        
    • modify xterm-24, xterm-bold, xterm-boldso entries to
        disentangle them from explicit dependency upon
        xterm-xfree86.
      • 

        
    • add generic 'xterm-color' entry.
      • 

        
    • minor corrections to xterm-xfree86, xterm-8bit,
        xterm-r5 and xterm-r6 entries.
      • 
      
    
    
    • 
  


  
Patch #78 - 1998/6/3 -
  XFree86 3.9Ah and 3.3.2


  
Again, most of the bulk of this patch is for ANSI conversion.
  I used the IRIX compiler's -wlint option to find the remaining
  functions that use K&R syntax (since gcc does not do this
  properly). Also, I changed the logic in the print code slightly
  to close unwanted files before opening a pipe to the printer.
  This may help in some configurations where the line printer hangs
  until xterm closes the pipe.


  
Patch #77 - 1998/5/26 -
  XFree86 3.9Ah and 3.3.2


  
Most of the bulk of this patch is to convert the extended C
  (K&R functions with prototypes) to ANSI. I verified that on
  Linux by comparing object files, to ensure that I did not, for
  example, interchange parameters in the function declarations.


  
The rest of the patch fixes several minor bugs, and adds a few
  features:


  
    
    
  • back-out my use of ncurses "captoinfo -f" option
    (if/then/else/endif) formatting, since ncurses did not
    correctly filter embedded newlines in terminfo capability
    strings until _after_ ncurses 4.1, thus corrupting
    setf/setb/sgr strings (reported by Darren Hiebert and
    others).
    • 

    
  • document SGR 8, 28 (invisible/visible), add corresponding
    capabilities to terminfo description.

      
    I would also add the 'prot protected capability, but the
      control sequences for that would not be recognized or
      properly ignored by the older xterm programs.
    
    
    • 

    
  • modify ChangeGroup to not suppress a null-resource, but
    treat it as an empty string (recommended by Stefan
    Dalibor).
    • 

    
  • add printerAutoClose resource to control whether printer is
    closed when going offline. More than one person reports
    problems (on Solaris 2.6 and Digital Unix 4.0) getting the
    printer to proceed unless xterm exits; I think that it is a
    problem flushing the pipe. Closing it ought to flush it.
    • 

    
  • adapt TOG fix-3 to in HandleKeymapChange and VTInitI18N
    (but adapt XtStackAlloc/XtStackFree for clarity, as well as
    fixing memory leak).
    • 

    
  • change calls on FillCurBackground to ClearCurBackground, in
    effect using XClearArea rather than XFillRectangle when
    clearing as a side-effect of scrolling and insertion (patch by
    Alexander V Lukyanov)
    • 

    
  • correct some places where insert/delete did not _move_ the
    color attributes, using memmove (patch by Alexander V Lukyanov
    <lav@long.yar.ru>)
    • 

    
  • add ifdef's for __CYGWIN32__, for port to cygnus version
    B19.1 (patch by Andrew Sumner
    <andrew_sumner@hotmail.com>).
    • 

    
  • remove #define for hpux that turned on USE_SYSV_ENVVARS,
    since this causes some applications (such as 'less') to get
    incorrect $LINES and $COLUMNS values (reported by Clint
    Olsen).
    • 

    
  • modify behavior for HP-UX, to set the "reserved" process
    group controls to _POSIX_VDISABLE so the TIOCSLTC ioctl does
    not produce an error (patch by Ben Yoshino
    <ben@wiliki.eng.hawaii.edu>).
    • 

    
  • correct length of underlining, reducing it by one pixel to
    avoid leaving a dot when the application does not clear the
    whole screen I noticed this only recently myself (and other
    people as well); it depends on the font chosen. A 6x10 font
    shows it, but the other fonts from XTerm.ad do not. I also see
    a similar problem with the emulation of bold fonts. (patch by
    Sergei Laskavy <Laskavy@cs.msu.su>).
    • 

    
  • add include for Xos.h to xterm.h, to ensure proper
    definitions (reported by Holger Veit).
    • 

    
  • update config.guess to recognize Unixware 2.1 and 7 (patch
    by Mike Hopkirk <hops@sco.com>).
    • 
  


  
Patch #76 - 1998/5/8 -
  XFree86 3.9Ah and 3.3.2


  
A fix for the print-window function, and some minor
  cleanup:


  
    
    
  • modify logic that closes pipe in the print-window function
    to not use pclose, which does not work on all systems, since I
    did not open the pipe with popen (reported by Stefan
    Dalibor).
    • 

    
  • correct name of $(EXTRA_LOAD_FLAGS) imake variable
    (reported by Stefan Dalibor).
    • 

    
  • guard logic in ChangeGroup() function against null pointer
    (reported by Stefan Dalibor).
    • 

    
  • ensure that menu entry for toggling sunKeyboard resource is
    initialized (reported by Branden Robinson
    <branden@purdue.edu>).
    • 

    
  • gcc unused-variable warnings (reported by Bernd Ernesti
    <bernd@arresum.inka.de>)
    • 

    
  • rename global variable 'buffer' to 'VTbuffer'
    • 
  


  
Patch #75 - 1998/5/7 -
  XFree86 3.9Ah and 3.3.2


  
This incorporates fixes from several people, as well as some
  improvements that I made based on feedback from users:


  
    
    
  • add option to standalone configure script,
    "--with-own-terminfo-dir", which causes xterm to pass a
    predefined value of $TERMINFO to the application. Also use this
    value in install rule "make install-ti", for the standalone
    configure script. (patch & feedback from Tor Lillqvist
    <tml@hemuli.tte.vtt.fi>)
    • 

    
  • change ifdef's for "hpux" to "__hpux" (patch by Tor
    Lillqvist). The imake configuration uses the former, but the
    latter is predefined by HP's compilers.
    • 

    
  • define USE_SYSV_ENVVARS for HP-UX, curses does not use
    $TERMCAP (patch by Tor Lillqvist).
    • 

    
  • on HP-UX, use the /dev/ptym/clone device to allocate PTY's.
    Works both on HP-UX 9 and 10. (patch by Tor Lillqvist).
    • 

    
  • modify configure script to obtain the $(EXTRA_LOADFLAGS)
    value from imake, needed for compiling under DEC OSF/1
    (reported by Stefan Dalibor)
    • 

    
  • modify print-window action so that the printer is closed
    after printing a window, unless the printer was already opened
    (i.e., by an application running in the window). This makes the
    printing complete without having to exit xterm, since not all
    systems treat fflush through a pipe very well (reported by
    Stefan Dalibor)
    • 

    
  • modify printing code so that the ^M's are not printed if
    the printAttribute resource is set to zero (request by Stefan
    Dalibor).
    • 

    
  • correct typo in xterm.man, for the default value of
    printAttribute (reported by Stefan Dalibor).
    • 

    
  • correct printing code so that the alternate character set
    is printed, like other attributes, with escape sequences.
    • 

    
  • correct termcap description, removing spurious 'm'
    character from the 'op' capability (reported by Greg Woods
    <woods@weird.com>).
    • 

    
  • correct trace code so that the initial timestamp is
    set.
    • 

    
  • correct/modify utmp data for the Linux glibc 2
    configuration, so that the ut_line member is set before using
    it to update wtmp (patch by Bill Nottingham
    <wen1@cec.wustl.edu>).
    • 
  


  
Patch #74 - 1998/4/27 -
  XFree86 3.9Ag and 3.3.2


  
This corrects a couple of recent bugs and adds a new
  resource:


  
    
    
  • modify definition of TRACE_CHILD so that it does not
    conflict with ifdef's for USE_USG_PTYS in main.c (reported by
    Vikas Agnihotri <VikasA@att.com> and Stefan
    Dalibor).
    • 

    
  • correct ownership of file (actually pipe) written by the
    print controls. When undoing the setuid changes in patch #69, I
    overlooked this. Now xterm forks a process which resets setuid
    and routes the printer data as the real user.
    • 

    
  • add a new resource, "printAttributes", which controls
    whether color attributes (or any attributes) are sent to the
    printer.
    • 
  


  
Patch #73 - 1998/4/25 -
  XFree86 3.9Ag and 3.3.2


  
This patch does the following:


  
    
    
  • implements a print-window facility for xterm. Though useful
    in itself, I added it as part of some debugging which I am
    doing. (Occasionally during an exposure event xterm fails to
    restore the proper colors for highlighted text, and printing
    the screen will show the internal states nicely).

      
    The print facility now also displays the color
      information. (I will probably make this a resource).
    
    
    • 

    
  • modified the xterm-16color terminfo description to use the
    setaf and setab strings, which is a little more efficient
    (requested by Stephen Marley).
    • 

    
  • reduced some clutter of the ifdef/includes (e.g., stdlib.h,
    unistd.h, errno) making the configure script test for these.

      
    I removed the symbols Size_t and Time_t, since they no
      longer serve a useful purpose.
    
    
    • 

    
  • added some debugging traces to show the initial screen
    size, and the success/failure of the ioctl calls pass handle
    window resizing events to the application (for Clint Olsen).

      
    I also modified the trace code to produce two files since
      some of the information is produced by the child process. So
      now they are Trace-parent.out and Trace-child.out
    
    
    • 

    
  • updated configure test for ANSI compiler options to handle
    a special case for HP-UX 10.x (reported by Clint Olsen).
    • 
  


  
Patch #72 - 1998/4/17 -
  XFree86 3.9Ag and 3.3.2


  
This is a patch from Chris Siebenmann
  <cks@hawkwind.utcs.toronto.edu>, which I have cleaned up a
  little, and integrated into the configure script.


  
From his description:


  

    
This set of patches is the latest incarnation of patches
    originally written by Ian! D Allen, then of the University of
    Waterloo and now of who knows where; I have been carrying them
    forward from xterm to xterm ever since about X11R4. What they
    do is add an option so that when an iconified xterm receives
    output it prepends '*** ' to its icon title and (optionally)
    beeps the bell; deiconifying the xterm removes the '*** '. Over
    the years I've found this to be incredibly convenient for
    monitoring all sorts of low-activity things.

  


  
Patch #71 - 1998/4/12 -
  XFree86 3.9Ag and 3.3.2


  
This patch is a slightly modified version of one by Richard
  Braakman, which prevents buffer overflow in the input-method and
  preedit-type parsing in xterm. I changed a couple of details to
  make the code more maintainable, and looked for similar things -
  copying into a fixed-size buffer (found none, though I did spot
  an unused variable).


  
Patch #70 - 1998/3/29 -
  XFree86 3.9Af and 3.3.2


  
This patch corrects some minor bugs in xterm, and fills in
  some more details in the VT220 emulation:


  
    
    
  • modify Imakefile to use SpecialCObjectRule for menu and
    data modules, making xterm build properly if logging is enabled
    (patch by Scott Sewall <scott@iprg.nokia.com>).
    • 

    
  • restore "ich" capability to terminfo entries, since Michael
    Schroeder points out that "ich1" is the one which is the
    problem in Solaris vi.
    • 

    
  • correct color of cursor, which would disappear on
    inverse-video since the initialization did not compare the
    cursor color against both foreground and background (reported
    by Olivier Calle).
    • 

    
  • correct abbreviation-test for -version and -help options,
    making command-line option -vb work (reported by Stefan
    Dalibor).
    • 

    
  • correct a dependency between ifdef's for OPT_I18N_SUPPORT
    and OPT_INPUT_METHOD (reported by Stefan Dalibor).
    • 

    
  • split-out character-set translations as new module
    charsets.c, to implement VT220 national replacement character
    sets (a mode where some of the characters are displayed as
    specific European glyphs). This relies on xterm using an ISO
    8859-1 font (approach suggested by Kenneth R. Robinette
    <zkrr01@mailbox.neosoft.com>).
    • 

    
  • correct a missing increment, which made SS2 and SS3
    controls repeat the shifted character.
    • 

    
  • add xterm-nrc to terminfo to illustrate the VT220 national
    replacement character sets.
    • 

    
  • reformat terminfo using new ncurses tic option "-f", which
    makes if/then/else/endif expressions easier to read.

Patch #69 - 1998/3/16 -
  XFree86 3.9Ad and 3.3.2


  
This corrects the problem in xterm with utmp, reported by
  Olivier Calle <olivier@tc.fluke.com> as well as some other
  people after the XFree86 3.3.2 release.


  
The error was introduced by my patch #53 in XFree86 3.9r
  (October 1997).


  
The correction removes the reset of setuid/setgid before the
  main event loop, and solves the problem which I had worked around
  in a different manner: for some reason, the particular waitpid()
  call in creat_as() hangs, does not return when the child process
  exits. I changed the ifdef's to force the Linux configuration to
  use wait() instead. This call appears to work properly on other
  platforms such as SunOS and Solaris.


  
I also added tests in the standalone configure script to check
  for the existence of waitpid().


  
Patch #68 - 1998/3/4 -
  XFree86 3.9Ad and 3.3.1z


  
This corrects another problem with the logic for
  highlightColor resource. As reported by David Dawes:


  

    
I've just noticed a problem with with the "inverse" control
    sequence (ESC[7m) with the 3.3.2 xterm. What it does is sets
    the background black, and the text the usual foreground colour
    rather than simply swapping the foreground/background.

  


  
This appears to be because when I added logic to check that
  the highlightColor was distinct from foreground and background
  colors, I did not add a further check to see that it was not
  black (I would make an explicit check for the resource not being
  set, but see nothing definite in the headers that would let me
  reference an explicitly-undefined Pixel value, though there are
  some implications in xpm.h). But this should work.


  
Patch #67 - 1998/2/23 -
  XFree86 3.9Ad and 3.3.1e


  
This patch does the following:


  
    
    
  • improve test for highlightColor so that xterm does not
    attempt to use that unless it is different from the foreground
    and background colors (reported by Stefan Dalibor
    <Stefan.Dalibor@informatik.uni-erlangen.de>.

      
    I could not reproduce this until I noticed that the -rev
      option exposed it nicely.
    
    
    • 

    
  • remove ich and ich1 from xterm and xterm-8bit terminfo
    descriptions. SVr4 terminfo documents that you must not combine
    these with smir/rmir, but ncurses allows it, opening a hole.
    Solaris 2.6 vi does not work properly if it is using a terminfo
    description when these are combined, since it was written to
    accommodate old terminals that required it (reported by Stephen
    Marley).
    • 

    
  • restore 1-pixel overlap of scrollbar border with left edge
    of window (reported by Jim Burmeister
    <jimb@metrolink.com>).
    • 

    
  • add a configure option, --enable-logfile-exec, which allows
    the user to specify a pipe for logfile. This defines
    ALLOWLOGFILEEXEC.
    • 

    
  • makes the ALLOWLOGFILEEXEC code compile & run, if
    configured.
    • 

    
  • minor documentation nits.
    • 
  


  
Patch #66 - 1998/2/16 -
  XFree86 3.9Ad and 3.3.1d


  
This fixes the problem reported with failure to build the
  resize program (BSDI, OSF/1) due to not having
  <termcap.h>, by changing the ifdef to one that would be set
  only if the file exists (not currently specified, except by the
  standalone configure script). We do not really need to include
  <termcap.h> to build, but only for a clean compile, since
  it may declare the tgetent() prototype. I also updated the
  man-page for resize, since I had recently noticed that
  it can be used to resize xterm using the "Sun" control
  sequences option.


  
Patch #65 - 1998/2/14 -
  XFree86 3.9Ad and 3.3.1c


  
This is a small patch to xterm's 8-bit terminal description. I
  noticed while testing ncurses that I had specified the wrong
  (VT100-style) codes for the F1-F4. Xterm only uses VT220-style
  function keys in 8-bit mode.


  
Patch #64 - 1998/2/8 -
  XFree86 3.9Ad


  
This fixes the following problems with xterm:


  
    
    
  • save/restore the ANSI foreground and background colors with
    the other visible attributes in the save-cursor and
    restore-cursor operations. This works around a problem with
    vim, which apparently assumed that switching between the normal
    and alternate screens resets the colors (reported by Jim Battle
    <jb@chromatic.com>).

      
    It would be nice to implement save/restore cursor as a
      stack (and solve this type of problem completely), but that
      would lead to incompatibility with applications which assume
      they are running with a VT100 or VT220.
    
    
    • 

    
  • corrects behavior of a restore-cursor operation which does
    not follow a save-cursor (it is supposed to set the character
    sets to a known initial state).
    • 

    
  • extends the sunKeyboard resource (and menu toggle) to
    modify the home, end and delete keys on a Sun or PC editing
    keypad, making them generate codes compatible with DEC VT220's
    Find, Select and Remove keys.
    • 

    
  • corrects a length in checking command-line options, which
    caused the "-help" message to not work when X was not
    running.
    • 

    
  • add some detail to the man-page (requested by Jason Bacon
    <acadix@execpc.com>)
    • 

    
  • modify the standalone configure script to ignore the broken
    nsl and socket libraries on IRIX 6.2 (the ones on 5.2 also are
    broken, so this change just widens the check for the system
    version number).
    • 
  


  
Patch #63 - 1998/2/5 -
  XFree86 3.9Ad


  
This is another patch from Bjorn Helgaas
  <helgaas@rsn.hp.com>, which I've reviewed (and learned
  some). Following are his notes:


  
I poked around some more and finally got xterm-62 to build and
  run cleanly on HP-UX 10.20. Here are the patches. They look sort
  of ugly, so here's a little explanation:


  
    
    
  • aclocal.m4: Removed side effects from the AC_CACHE_VAL
    commands in CF_FUNC_TGETENT. Previously, LIBS was set inside
    AC_CACHE_VAL, which worked fine the first time configure was
    run, but failed if there were cached values.
    • 

    
  • aclocal.m4: Added temporary setting of LIBS before
    AC_TRY_LINK in CF_FUNC_TGETENT. Previously, the last value set
    by the AC_TRY_RUN loop was used, so only -lcurses was
    checked.
    • 

    
  • configure.in: Added temporary setting of CPPFLAGS before
    AC_CHECK_HEADERS for X11 files. Previously
    <X11/DECkeysym.h> and <X11/Xpoll.h> were found only
    if they were in the compiler's default include directories,
    even if `--x-includes=DIR' had been used or AC_PATH_XTRA had
    found them elsewhere.
    • 
  


  
The problem on HP-UX was that we were linking with -lcurses
  rather than -ltermcap due to the second bullet above, and
  apparently something in HP-UX curses is broken. This seems very
  strange, because the only thing used is tgetent, which should
  affect any tty/pty configuration, but I lost interest in tracking
  down the exact problem.


  
Patch #62 - 1998/1/23 -
  XFree86 3.9Ac


  
This is a patch mostly by Bjorn Helgaas
  <helgaas@dhc.net> (I added the os2main.c change, and a
  little of the documentation). From Bjorn's description:


  
    
    
  • If you use the "-hc <color>" option or set the
    "highlightColor" resource, text is highlighted by changing only
    the background color, rather than using reverse video. I find
    this easier to read, especially when selecting multi-colored
    text, and it is similar to the way Netscape shows
    selections.
    • 

    
  • Most of the code changes are under "#if
    OPT_HIGHLIGHT_COLOR". The principal exception is in screen.c,
    where I added a couple calls to resetXtermGC(). This seems like
    it could be a bug even without the color highlighting changes
    (though I don't pretend to understand all the logic).
    • 
  


  
Patch #61 - 1998/1/17 -
  XFree86 3.9Ac


  
This patch modifies the reset behavior of xterm slightly:


  
    
    
  • change the terminfo entry so that rs1 (one of the strings
    used by the 'reset' program) does a hard reset rather than
    switching character sets. This is more in accord with other
    terminal descriptions.
    • 

    
  • modifies the treatment of hard reset by the xterm program
    to reset the saved lines.
    • 

    
  • corrects hard reset by also resetting user-defined keys,
    i.e., DECUDK.
    • 
  


  
Patch #60 - 1998/1/10 -
  XFree86 3.9Ab


  
This fixes some minor bugs and adds new functionality:


  
    
    
  • add support for blinking text.

      
      
        
    • This does not actually cause the text to flash, but
        text with the blink attribute can be displayed in color,
        using new resources colorBL and colorBLMode.
      • 

        
    • If colors are not used, the blinking text will be
        displayed as before (just like bold). The main purpose of
        this is to make applications work properly when they assume
        the emulator supports blinking text.
      • 

        
    • I did this by moving the per-cell LINEWRAPPED flag to a
        per-line flag, to make room for the new BLINK flag. There
        were no per-line flags, so this changes a lot of
        logic.
      • 
      
    
    
    • 

    
  • corrected missing save-cursor logic in the handling of SGR
    1048 (the new control sequence I added in patch #54,
    1997/10/17). Reported by Darren Hiebert.
    • 

    
  • flush the output of the transparent printing after each
    line Reported by Tomas Vanhala
    <vanhala@ling.helsinki.fi>.
    • 

    
  • correct the modes that are affected by save/restore cursor
    by adding WRAPAROUND and PROTECTED.
    • 

    
  • corrected placement of one of the XSync calls that I added
    in patch #51, 1997/9/15, which had the side-effect of writing
    on the window border when the xterm was resizing from 132 to 80
    columns.
    • 

    
  • work around an incompatibility of the XKB definition used
    in xterm versus that symbol from IRIX 6.2's imake definitions
    (by adjusting the standalone configure script).
    • 
  


  
Patch #59 - 1998/1/5 -
  XFree86 3.9Ab


  
My last patch has an off-by-one error in the comparison for
  argc. Douglas Kosovic <douglask@dstc.edu.au> showed me
  where (he got a core dump). Also, I think this explains Clint
  Olsen's problem, but the symptoms were more subtle (EINVAL for a
  system call if the -display option is omitted).


  
Patch #58 - 1998/1/3 -
  XFree86 3.9Ab


  
This patch does the following:


  
    
    
  • implement logic to permit xterm to work with proportional
    fonts.

      
      
        
    • Thomas Wolff <Thomas.Wolff@sietec.de> requested
        this (but it isn't exactly what he's asking for - that's a
        more involved task).
      • 

        
    • I chose to do this by rendering the characters on a
        fixed pitch, because it would not be useful for existing
        applications to display varying numbers of characters on
        each line.
      • 

        
    • Except that this forces the display to be wider, it
        works reasonably well. A couple of special cases (reverse +
        colorBD, for example) do not display with proper colors,
        since the inter-character gaps are painted with the
        background.
      • 
      
    
    
    • 

    
  • added a version number to the program (several people have
    requested this).
    • 

    
  • make the -version and -help options interpreted before the
    program attempts to open the display.
    • 

    
  • minor reorganization of the man-page (ordered the options,
    resources and translations alphabetically - and eliminated some
    duplication).
    • 

    
  • corrected a misspelled filename in Makefile.in, and added a
    lint rule.
    • 

    
  • updated the configure script to correct behavior when it
    cannot find imake, as well as to fix the IRIX+gcc build
    (conflict with /usr/include).
    • 

    
  • regenerated the configure script with a newer patch to
    autoconf that fixes a problem with environment space vs the
    configure --help message.
    • 
  


  
Patch #57 - 1997/12/26 -
  XFree86 3.9Aa


  
This patch is mostly concerned with the standalone configure
  script; a few minor corrections are added:


  
    
    
  • add configure option --disable-tek4014, to allow xterm to
    be built without the tek4014 emulation.
    • 

    
  • add configure option --with-terminal-type, to allow xterm
    to be compiled with default $TERM value other than "xterm"
    (e.g., "xterm-16color") -- requested by Stephen Marley
    <stephen@memex.com>.
    • 

    
  • fix a typo in the configure --help message -- reported by
    Darren Hiebert <darren@hmi.com>.
    • 

    
  • review diffs between main.c and os2main.c, to make them
    more alike. (applies some minor bug-fixes to OS/2's
    version).
    • 

    
  • add missing quotes in memmove/bcopy configure test
    • 
  


  
Patch #56 - 1997/11/28 -
  XFree86 3.9x


  
This patch is based on analysis by Arfst Ludwig
  <arfst@luxor.IN-Berlin.DE>, who reported:


  

    
Setting the following resources xterm (all current versions)
    receives a segmentation fault on <Btn2Up> after
    scrolling:

    
          *XTerm*VT100*translations:    #override \
              ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0)\n\
              Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1)\n\
              ~Shift<BtnUp>:       select-end(PRIMARY, CUT_BUFFER0)\n\
              Shift<BtnUp>:        select-end(CLIPBOARD, CUT_BUFFER1)



    
(The above resources intention is to be able to paste the
    latest selection even if the xterm was cleared.)


    
And here is how it works (and a fix!): The widget given to
    the action handler as first argument is not guaranteed to be a
    XtermWidget (it can be the ScrollbarWidget). Instead of
    accessing the widget's member directly XtDisplay gives the
    required pointer in a safe way.

  


  
I noticed that this was not the only instance (by reading the
  code, and testing with his example), and extended the solution to
  check the widget-class to ensure that it is indeed xterm's widget
  class before attempting to use it in the context of
  translations.


  
Patch #55 - 1997/11/25 -
  XFree86 3.9x


  
This fixes the segmentation violation noted by Rogier Wolff
  about a month ago. He'd set xterm to 400 (rows) by 150 columns,
  which broke because there were limited buffers (200 rows) used
  for juggling data when adding or deleting lines and for switching
  between alternate and normal screens. I replaced this by an
  allocated buffer.


  
The bug is simple to test if you set titeInhibit false.


  
Patch #54 - 1997/10/17 -
  XFree86 3.9s


  
This patch does the following:


  
    
    
  • correct a minor placement problem with the right
    scrollbar.
    • 

    
  • implement a new set of control sequences for switching
    between the normal and alternate VT100 screens. These work
    around the older sequences limitation that required
    modification of the runtime $TERMCAP to cooperate with the
    titeInhibit resource (that can't work with terminfo). I do this
    by moving all of the functionality of the rmcur terminfo
    capability into the control sequences.
    • 

    
  • implement the alternate-screen menu entry
    • 
  


  
Patch #53 - 1997/10/12 -
  XFree86 3.9r


  
This patch adds a fix and implements a new feature (as well as
  some minor typos):


  
    
    
  • JCHANDRA@Inf.COM (JCHANDRA) noted that there was still a
    problem with the wait call with the logging option. It hung
    when the logfile was opened as a command-line option. I fixed
    this by moving the StartLogging() call down past the place
    where I'd reset the setuid mode. So the logfile is opened as
    the real user, without having to fork.
    • 

    
  • improve Rohleder's changes by renaming the command-line
    options and reducing the number of ifdef's.
    • 

    
  • implement right-scrollbars for xterm (patch by Michael
    Rohleder <michael.rohleder@stadt-frankfurt.de>).
    • 
  


  
Patch #52 - 1997/9/29 -
  XFree86 3.9q


  
This patch addresses bugs and requests reported by


  
    
    
  • Bob Maynard <rmaynard@montana.com>,
    • 

    
  • Clint Olsen <olsenc@ichips.intel.com>,
    • 

    
  • JCHANDRA@Inf.COM (JCHANDRA),
    • 

    
  • Michael Schroeder
    <Michael.Schroeder@informatik.uni-erlangen.de>,
    • 

    
  • Pablo Ariel Kohan <pablo@memco.co.il>
    • 
  


  
Some of the changes are interrelated (it was an unusually busy
  week).


  
    
    
  • change the default resource value for colorMode to true,
    matching the Xterm.ad file.
    • 

    
  • correct behavior of 'ech' control, making the default and 0
    parameters erase one character rather than to the end of line
    (reported by Michael Schroeder).
    • 

    
  • add resource boldColors, command-line options +pc and -pc
    and configure-script option to specify behavior of xterm's
    mapping bold colors 0 through 7 to colors 8 through 15.
    (request by Pablo Ariel Kohan).
    • 

    
  • add resource colorAttrMode to specify whether colorULMode
    and colorBDMode can override the ANSI colors (report by Clint
    Olsen).
    • 

    
  • correct a conflict between colorULMode/colorBDMode versus
    ANSI colors, where exposure events would occasionally pick up
    the former (e.g., colorBD) rather than ANSI colors. Testing the
    colorAttrMode made this apparent, though it has been in the
    code since 3.2A (patch #35 in Jan 1997).
    • 

    
  • correct two problems with the optional logging support. On
    Linux at least, the waitpid call in creat_as hangs when the
    logging is toggled from the popup menu. Also, the mktemp
    template has the wrong number of X's (since X11R5!). Fixed the
    waitpid problem by exploiting the fact that the setuid behavior
    is reset before the popup menus are available. (reported by
    Jayachandran C.).
    • 

    
  • add configure script options for building with the Xaw3d
    and neXtaw libraries.
    • 

    
  • correct CF_IMAKE_CFLAGS standalone configure script macro,
    so that it will pick up $(ALLDEFINES) rather than
    $(STD_DEFINES). This is needed to make scrollbars work on
    Linux, since that uses narrow prototypes. (reported by Bob
    Maynard).
    • 

    
  • various minor updates to configure-script macros.
    • 
  


  
Patch #51 - 1997/9/15 -
  XFree86 3.9p


  
Most of this patch is related to the standalone configure
  script, though there are fixes/enhancements as well:


  
    
    
  • add a new resource sunKeyboard, with associated
    command-line option and menu-toggle that allows using a normal
    Sun or PC keyboard to generated the complete DEC-style function
    keys and keypad.
    • 

    
  • correct a reversed foreground/background test in the
    control sequence that replies with the current SGR
    settings.
    • 

    
  • correct, by invoking XSync, a display problem that caused
    the program to not properly update newly exposed areas when a
    font change or 80/132 resize request was not completely
    accepted.
    • 

    
  • restructured autoconf macros (I made a library of all of
    the macros across the complicated configure scripts I'm working
    on).
    • 

    
  • use the autoconf config.guess and config.sub scripts to
    better identify the host-os.
    • 

    
  • improve the configure script that uses 'imake' as a
    fallback for definitions.
    • 

    
  • correct several instances of unsigned/signed mixed
    expressions.
    • 
  


  
I've tested the configure script on Linux, SunOS 4.1.3,
  Solaris 2.5.1, IRIX 5.2 and 6.2, AIX 3.2.5 and CLIX 3.1 (all but
  the last run properly as well).


  
Patch #50 - 1997/8/22 -
  XFree86 3.9m


  
This is a collection of small fixes, and a couple of minor
  enhancements:


  
    
    
  • plug a security hole in the implementation of Media Copy
    (print) by invoking setuid just before the main loop.
    • 

    
  • add an ifdef'd include for <sys/termio.h> for HP-UX,
    which allows the program to process SIGWINCH events (this is a
    bug in X11R6.3)
    • 

    
  • add state-table entries for VT52 emulation to enter/exit
    keypad application mode.
    • 

    
  • disable the popup-menu entry for 8-bit controls when the
    terminal-id is less than 200 (e.g., VT52 or VT100).
    • 

    
  • ensure that the popup-menu entry for 8-bit controls is
    updated when the application enables/disables this mode,
    including the response to a full-reset.
    • 

    
  • implement VT300 DECBKM feature: set interpretation of the
    backarrow key to either backspace or delete. The initial
    setting is via resource; it can also be modified in the main
    popup menu.
    • 

    
  • implement VTxxx KAM (ISO AM), which allows a keyboard to be
    locked (i.e., the terminal discards input).
    • 

    
  • implement VTxxx SRM, which is used to control local echoing
    of input on the terminal.
    • 

    
  • add terminfo and termcap entries for xterm-8bit, a
    variation of the xterm description that uses 8-bit control
    characters.
    • 

    
  • add fallback definitions for Imakefile to allow it to work
    on some X11R5 systems that have no SpecialCObjectRule or
    ProgramTargetName macros.
    • 

    
  • add .c.o and .c.i rules to standalone Makefile.in
    • 

    
  • correct order of -lXmu and -lXext in standalone configure
    script.
    • 

    
  • add configure script options to allow selective disabling
    of active-icon, input-method and i18n code (mainly for users
    with X11R5 or an incomplete X11R6 configuration).
    • 

    
  • change menu-indices from #define's to enum values, thereby
    making it work better with the ifdef's for logging and
    active-icon (the X11R6.3 active-icon code is incorrectly
    ifdef'd; this corrects an error introduced by incorporating
    that code).
    • 

    
  • correct minor compile errors in the configuration where
    active-icon is not used.
    • 

    
  • add configure option to suppress echoing of long compiler
    commands
    • 

    
  • correct spelling of decTerminalID in configure script help
    message
    • 

    
  • use gcc __attribute__((unused)) to quiet warnings about
    unused parameters when compiling with -W (to make it simpler to
    find the real problems).
    • 
  


  
Patch #49 - 1997/8/10 -
  XFree86 3.9k


  
This patch implements the VT100/VT220 Media Copy (i.e.,
  print-screen) control sequences.


  
Patch #48 - 1997/7/26 -
  XFree86 3.9j


  
This patch does the following (all but the first affect only
  the standalone configure script):


  
    
    
  • minor correction to positioning of underlines for small
    (e.g., 5x8) font size.

      
    The existing behavior allowed underlines to be drawn
      outside the character-cell, so they weren't cleared properly
      under some circumstances.
    
    
    • 

    
  • adds more special-case tokens to the standalone configure
    script's imake-option filter (e.g., "&&", since a "make
    -n main.o" on my IRIX system uses that shell construct).
    • 

    
  • adds a '--enable-logging' option for the standalone
    configure script.
    • 

    
  • adds check and ifdef's for the standalone configure script
    to allow for building on platforms with X11R6, which lacks
    Xpoll.h (introduced in X11R6.1).
    • 
  


  
Patch #47 - 1997/7/13 -
  XFree86 3.9i


  
This patch does the following


  
    
    
  • corrects an indexing error in the doublesize character
    logic (button.c) that caused core dump (this was reported by J.
    Wunsch).
    • 

    
  • corrects the logic of ShowCursor when it is painting in a
    doublesize cell (charproc.c).
    • 

    
  • corrects, according to vttest, the behavior when switching
    to doublesize characters and back again (doublechr.c).
    • 

    
  • adds cbt (back_tab) to the terminfo description (this was
    something that I'd overlooked as applicable to curses
    optimization last summer).
    • 

    
  • corrects, for the standalone xmc test, the logic for
    disabling xmc.
    • 
  


  
Patch #46 - 1997/7/4 -
  XFree86 3.9h


  
This is a patch to provide test-support for some work I'm
  doing on ncurses. It does not modify the normal configuration of
  xterm; the code is compiled if the standalone configure option
  "--enable-xmc-glitch" is specified.


  
Patch #45 - 1997/7/2 -
  XFree86 3.9h


  
This fixes the problem reported with xterm's cursor color
  versus the background (the second chunk in this patch) and also
  removes some duplicate initialization of the cursor GC's. If the
  cursor color at startup is the same as the background, then xterm
  will use the reverse GC, ignoring the setting of the colorMode
  resource.


  
Patch #44 - 1997/6/22 -
  XFree86 3.9g


  
This implements the first part of the VT100 doublesize
  characters for xterm, as well as fixing a handful of bugs:


  
    
    
  • the doublesize character support uses the normal font
    (using scaled fonts will be another patch) with blanks to
    simulate doublesize characters. This patch does most of the
    global changes that'll be required. I've hidden most of the
    details in macros and ifdef's so it's easy to configure out
    (part of the patch is a configure option for that
    purpose).
    • 

    
  • corrected limits in DeleteChar() function -- it's always
    ignored the size of the left border and scrollbar. I noticed
    this when working on the doublesize characters since the glitch
    was doubled in size (i.e., it wrapped some garbage around the
    right margin).
    • 

    
  • corrected 'memmove()' logic, for standalone builds (it
    referenced a malloc wrapper from my development library).
    • 

    
  • add a check for HideCursor() to prevent repeated screen
    updates (which can cause a spurious cursor glitch to appear,
    e.g., during scrolling). I noticed this with the 3.2A version
    (but only a few weeks ago, when I started working on this
    patch).
    • 
  


  
Patch #43 - 1997/6/10 -
  XFree86 3.9d


  
Here's a fix for two problems:


  
    
    
  • modify handling of tgetent results in xterm and resize
    programs to make them tolerant of missing termcap file, or
    unknown terminal name. In this scheme, an explicit "-tn" option
    will succeed, overriding the fallback list.
    • 

    
  • a nit in the configure script (log extra information to
    help diagnose which case of the test-compile of tgetent was
    used).
    • 
  


  
Patch #42 - 1997/6/8 -
  XFree86 3.2Xl


  
Bram Moolenaar reported that the cursor color changed
  unexpectedly while scrolling. The cause was that it used the same
  GC's as the logic that draws the ANSI colors. The bug only
  appears if the cursorColor resource isn't set, and has been
  present since the initial implementation early last year. (The
  same bug also appears in rxvt ;-). Here's a fix.


  
Patch #41 - 1997/5/28 -
  XFree86 3.2Xl


  
Some nits found by Darren Hiebert (missing part of
  install-rule, incorrect assignment for --enable-color-mode
  option).


  
Patch #40 - 1997/5/26 -
  XFree86 3.2Xl


  
Patch for the configure script's logic for obtaining imake
  predefined symbols.


  
Patch #39 - 1997/5/24 -
  XFree86 3.2Xl


  
This patch does the following:


  
    
    
  • integrate the 16-color change for 'xterm'
    • 

    
  • minor fixes/clarification of tgetent in terminfo vs termcap
    to 'resize'
    • 
  


  
(both changes also modify the configure script)


  
Patch #38 - 1997/5/22 -
  XFree86 3.2Xh


  
This implements a simple configuration script with autoconf
  (to which I'll add more options later). It does the
  following:


  
    
    
  • configures xterm to build with X11R5 (at least on SunOS
    4.1, Solaris 2.4, possibly IRIX - sorry network was down today,
    but I did test an earlier version yesterday).
    • 

    
  • enables/disables the configuration ifdef's for ANSI color
    and VT52 emulation.
    • 
  


  
It does not make tests for the things that imake does (that's
  another project), instead it uses a hybrid of the autoconf tests
  for libraries and adds imake's compiler options (which are
  necessary in some cases to get main.c to compile).


  
Patch #37 - 1997/5/7 -
  XFree86 3.9a


  
This corrects a minor, but annoying error in the vt220
  emulation: the DECUDK is only supposed to be interpreted for
  _shifted_ function keys.


  
Patch #36 - 1997/1/16 -
  XFree86 3.2r


  
This corrects something that I overlooked in patch #27
  (21-aug-1996), which is that when trimming the region to be
  repainted for the highlightSelection resource of xterm, I still
  have to paint the background past the highlighted region. This
  only happens when I first do a selection in a window that's
  partly off-screen, then move the window on-screen.


  
Patch #35 - 1997/1/7 -
  XFree86 3.2o


  
This patch does the following:


  
    
    
  • combines the coding for foreground and background colors
    into a single byte, reducing the memory required to store
    saved-lines in color. (I'll take back that byte in a following
    patch to use to ensure the character-set, so there's no
    long-term decrease in memory use).
    • 

    
  • modifies the PF1-PF4 coding in termcap/terminfo. Because
    xterm is still by default emulating vt100, the function key
    codes are vt100-compatible (I overlooked this in patch #31). I
    also reformatted the whole terminfo file into a single-column,
    for consistency.
    • 

    
  • adds an interim xterm-vt220 description to accommodate the
    old and new styles of function-keys (though probably it'd be
    better to drop the old-style altogether).
    • 
  


  
Patch #34 - 1997/1/5 -
  XFree86 3.2o


  
This patch does the following:


  
    
    
  • implement DECSTR (soft terminal reset). The biggest diff is
    due to adding another state table (note that there's only one
    useful state here, but it's only 256 bytes rather than 1k as it
    would have been before I reduced the size of state
    entries).
    • 

    
  • some minor tidying up (e.g., signed/unsigned use bitcpy,
    MODE_DECCKM, resetColor, resetCharsets). More is done in patch
    #35.
    • 
  


  
I got the description of DECSTR from a vt420 user's manual.
  I'll do some testing with vttest to ensure that there's nothing
  else to do than what was documented.


  
Patch #33 - 1996/11/24 -
  XFree86 3.2


  
This adds to the reset-fix by Matthieu Herrb
  <Mathieu.Herrb@mipnet.fr> a small change to make xterm able
  to output 8-bit characters in VT100 mode. Applications that run
  on real VT100's don't do that anyway, and this feature should be
  removed sometime after finishing off the VT220 emulation (VT220's
  can do 8-bit characters). That would be a good time to change the
  default terminal-id to 220.


  
Patch #32 - 1996/11/21 -
  XFree86 3.2


  
This implements the REP (repeat) control for xterm. That isn't
  part of the DEC VTxxx series, but is defined in ISO 6429. (Note
  that the base xterm terminal description is not changed
  -- I added a variant, "xterm-rep").


  
Patch #31 - 1996/11/16 -
  XFree86 3.2


  
This implements vt52 emulation in xterm (ifdef'd so it can be
  removed). I've been using it for testing for the past month or
  so.


  
Patch #30 - 1996/11/16 -
  XFree86 3.2


  
From bug-report by <auroux@clipper.ens.fr> (Denis
  Auroux), missing reset to ground state. I checked through the
  rest of that table and found another, in the
  unimplemented MC (screen print).


  
Patch #29 - 1996/9/15 -
  XFree86 3.1.2Gb


  
This patch does the following:


  
    
    
  • corrects the restoration of color for bold/underline color
    mode
    • 

    
  • adds a resource 'decTerminalID' to control the reporting
    level of xterm (e.g., VT100, VT220).
    • 

    
  • uses the new resource to implement/correct the DA1, DA2 and
    DECRPTUI reports.
    • 

    
  • change valid-response code in DECRQSS from 0 to 1 (the
    manual says 0, but the VT420 terminal I've been testing on says
    1).
    • 
  


  
All of these changes are based on vttest 2.6


  
(Most of the volume in the patch is to add 2 more state tables
  for parsing the 2nd/3rd device-attribute controls).


  
Patch #28 - 1996/8/31 -
  XFree86 3.1.2F


  
This patch corrects the following reported by Roland Rosenfeld
  <roland@spinnaker.rhein.de>:


  
    
    
  • handle SGR 22, 24 and 25 in combination with colorUL and
    colorBD resources. Also noted & fixed reset of colored
    underline/bold with SGR 0.
    • 

    
  • a typo in the termcap (missing '['), from 3.1.2Dj (my
    error)
    • 
  


  
Roland also complained that he couldn't use box characters
  with

  
        -adobe-courier-bold-r-normal--12-120-75-75-m-70-iso8859-1



  
but that's a known xterm limitation (the box characters must
  be part of the font, in the first 32 locations).


  
Patch #27 - 1996/8/21 -
  XFree86 3.1.2Ek


  
This patch fixes one of my long-term gripes: xterm's selection
  doesn't clearly show what's being selected (as per David's
  request, it's controlled by a resource, which defaults to the
  older behavior).


  
Patch #26 - 1996/8/20 -
  XFree86 3.1.2Ei


  
Here's a patch to fix a problem with xterm's cut/paste and
  another to modify the appearance of the highlighting while
  selecting. (The changes are independent, so you can see if the
  change to screen.c is desirable).


  
Patch #25 - 1996/8/18 -
  XFree86 3.1.2Ei


  
Here's a correction for two minor bugs that I picked up in
  testing, plus some lint (from Solaris 2.5) where NULL was used
  incorrectly:


  
    
    
  • make the second alternate font the same as the first
    (that's what vt420 and dtterm do)
    • 

    
  • corrected DECSCL report when DECSCL hasn't been set (i.e.,
    don't return a '60').
    • 
  


  
Patch #24 - 1996/8/11 -
  XFree86 3.1.2Ee


  
This patch does several things. In effect, xterm can (I think)
  do a reasonably good job of emulating vt220 and vt320 terminals
  (as well as it was doing vt100, at any rate ;-).


  
It does NOT do:


  
    
    
  • soft fonts
    • 

    
  • rigel or sixel graphics
    • 
  


  
Anyway, I:


  
    
    
  • added ECH, CPL, CNL, SU, SD, CBT, CHT controls
    • 

    
  • added popup-menu for switching between DEC and Sun function
    keys. (corrected alignment err wrt logging entry at that
    point).
    • 

    
  • make xterm recognize both 8-bit and 7-bit controls
    (including popup menu for switching modes).
    • 

    
  • add user-definable function keys (aka DECUDK)
    • 

    
  • support concealed text
    • 

    
  • support protected text (both ISO compatible and DEC
    compatible - that's not the same thing, btw), with SPA, EPA,
    DECSCA, DECSED, DECSEL controls.
    • 

    
  • implement DECSCL.
    • 
  


  
I'll be continuing to test this patch for a while, but don't
  expect to add any new functionality (it passes all of the current
  tests I've built in vttest, but I need to make more tests)..


  
Patch #23 - 1996/7/31 -
  XFree86 3.1.2Ec


  
This removes the blinking cursor I added last week (for
  performance reasons). Time-permitting, I'll revisit this after
  3.2 is released (there will be more work after XFree86
  3.2, I assume).


  
Patch #22 - 1996/7/26 -
  XFree86 3.1.2Ec


  
I looked more closely at my "double-negative" and realized
  that I had been confused by the default color scheme (black on
  white) in combination with reverse video. However, I did see that
  the original_fg and original_bg data weren't really used - so I
  removed that logic.


  
Also:


  
    
    
  • during initialization, check if ANSI colors are set with
    non fg/bg values, disable color mode if not. This makes xterm
    tolerant of applications that allocate the whole color
    map.
    • 

    
  • implemented blinking cursor (default is off)
    • 
  


  
Patch #21 - 1996/7/24 -
  XFree86 3.1.2Ec


  
This patch does the following:


  
    
    
  • fixes some minor typography in the control-sequences
    documentation (it didn't occur to me til I'd sent the last
    patch that I could use ghostview for previewing the troff
    output ;-)
    • 

    
  • adjusts the shell's background color in ReverseVideo so
    that flicker in resizing is reduced
    • 

    
  • adds an ifdef OPT_ISO_COLORS to allow configuring xterm
    without the ISO color support (saves a lot of memory)
    • 

    
  • used that ifdef to isolate/modify logic so that if the user
    doesn't have the colorMode enabled, then ISO color support is
    disabled (saving memory).

      
    (If anyone needs numbers, I had savedLines set to 2000,
      and found a reduction from ~700k to ~400k of allocated
      memory, according to Purify).
    
    
    • 
  


  
Patch #20 - 1996/7/24 -
  XFree86 3.1.2Ec


  
This documents the changes in control sequences for window
  operations that I added in my previous patch. I'm testing another
  patch that allows the user to use less memory if colors aren't
  needed.


  
Patch #19 - 1996/7/21 -
  XFree86 3.1.2Ec


  
This patch does the following:


  
    
    
  • fixes the core dump that I reported on IRIX 5.2 (in main.c)

      
    (it's worth noting that this bug exists in X11R6.1, so I'd
      like to assume that someone's already submitted a fix to X
      Consortium...)
    
    
    • 

    
  • change the interpretation of zero rows or columns in a
    resize-window request to use the root window's size (looking
    more carefully at dtterm, that seems to be what it does).
    • 

    
  • change some memmove calls to memcpy for slightly better
    performance. also, a couple of memset calls to bzero, since
    Quantify says bzero runs 20% faster, I assume because there's
    one less argument.
    • 

    
  • interpret character sets 1 and 2 (so that vttest gives a
    reasonable result) Both rxvt and dtterm do something
    equivalent.
    • 

    
  • fix a minor memory leak in the logic that retrieves the
    window or icon names (Purify found this for me while I ran
    vttest).
    • 
  


  
Patch #18 - 1996/7/18 -
  XFree86 3.1.2Ec


  
This implements the following:


  
    
    
  • escape sequences that act like the CDE dtterm's window
    operations (though I have implemented the default width and
    height -- I've seen a rather buggy dtterm running that seems to
    treat width=0 or height=0 literally -- maybe that's a feature,
    not a bug?)
    • 

    
  • minor tweak to the screen-repainting when resizing (I still
    cannot entirely get rid of flicker).
    • 

    
  • still more fixes to terminfo & termcap (I corrected my
    error for the hpa code and added some other stuff by comparing
    to ncurses' description and rxvt's).
    • 

    
  • a tweak to the changes by Michael Rohleder for the color
    translation
    • 

    
  • re-order attribute codes to allow later implementation of
    protected fields (dtterm supposedly does this; it's probably
    more useful than blinking or invisible text -- that uses up all
    of the available bits without changing the attribute scheme
    radically).
    • 
  


  
Patch #17 - 1996/7/2 -
  XFree86 3.1.2Eb


  
This patch implements for xterm several minor features from
  ISO 6429 which are useful for terminfo applications. The HPA and
  VPA control sequences allow cursor movement along a row or
  column, cutting down a little on the characters transmitted. The
  other codes allow resetting specific graphic rendition attributes
  without modifying the other attributes. (now if someone just had
  time to implement blinking cursors...)


  
Patch #16 - 1996/6/25 -
  XFree86 3.1.2Ea


  
Adam Tla/lka <atlka@pg.gda.pl> told me a couple of weeks
  ago that I'd missed some of the background coloring in xterm. I
  investigated, and found that while I'd picked up on the
  clear-to-bottom and clear-to-end-of-line operations, I'd
  overlooked the insert/delete lines. Just so I wouldn't overlook
  any more of these, I updated a copy of vttest to test ISO colors
  and bce (background color erase). This patch introduces a new
  function, ClearCurBackground, whose calls replace the direct
  XClearArea calls that I'd overlooked. (There's also a few
  compiler warnings fixed, etc ;-)


  
Patch #15 - 1996/5/29 -
  XFree86 3.1.2E


  
This fixes the problem reported by David Dawes, by making the
  50msec select timeout for the Xaw3d arrow scrollbar a resource.
  (I made it a boolean for a variety of reasons -- to make it a
  number, you'd need an additional resource, to avoid breaking the
  logic).


  
Patch #14 - 1996/5/12 -
  XFree86 3.1.2Dj


  
This patch brings the termcap and terminfo descriptions for
  xterm up to date. I made the following changes:


  
    
    
  • reformatted the terminfo description in a single-column
    (this is ok for terminfo, and will simplify future patches --
    can't do that for termcap, since it would impact buffer
    requirements on some systems).
    • 

    
  • omitted obsolete features in termcap to save a little space
    (bs, pt)
    • 

    
  • added color capabilities to termcap (ut, Co, NC, op, AB,
    AF)
    • 

    
  • corrected some capabilities (vi, ve)
    • 

    
  • added 'st' (set tab)
    • 

    
  • reduced function keys in termcap for 'xterm' to 12 because
    color capabilities makes that description larger than 1023
    characters.
    • 

    
  • created new termcap name 'xtermm' (monochrome) to match the
    terminfo list, and make that description have 20 function
    keys.
    • 

    
  • added corresponding color capabilities to terminfo (bce,
    colors, pairs, op, ncv, setab, setaf)
    • 

    
  • corrected corresponding capabilities in terminfo (civis,
    cnorm, rmcup, smcup)
    • 

    
  • added capabilities (el1, hts)
    • 

    
  • in both, corrected home/end keys to match the code
    correction made by Thomas Mueller in 3.1.2Bk

      
    => (I'm still considering modifying the code &
      description to match the rxvt program).
    
    
    • 
  


  
Patch #13 - 1996/4/23 -
  XFree86 3.1.2Df


  
This corrects my earlier changes for colors - the inner border
  of the xterm was getting painted with the wrong color, since I'd
  moved the call to set the background into the logic that tracks
  SGR information.


  
Patch #12 - 1996/3/16 -
  XFree86 3.1.2Dc


  
This corrects a memory leak in xterm that happens whenever one
  switches fonts.


  
Patch #11 - 1996/3/5 -
  XFree86 3.1.2Db


  
This patch corrects the behavior of the ANSI colors in xterm
  when reverse video is used, as well as some other lesser
  sins:


  
    
    
  • button.c

      
      
        
    • (compiler warnings: shadowing of 'time', redundant
        cast)
      • 
      
    
    
    • 

    
  • charproc.c

      
      
        
    • renamed screen.colors[] array to screen.Acolors[] to
        more easily distinguish the non-ANSI colors from the ANSI
        colors.
      • 

        
    • moved logic of SGR_Save() into VTInitialize, getting
        rid of local private variables original_fg and
        original_bg.
      • 

        
    • moved some logic into getXtermForeground and
        getXtermBackground from SGR_Foreground, SGR_Background,
        etc.
      • 

        
    • corrected misleading 'row' to 'col' in case for CUF,
        CUB sequences.
      • 
      
    
    
    • 

    
  • ctlseqs.ms
    • 

    
  • xterm.man

      
      
        
    • (correct a misconception which I'd added that the
        color0 through color6 resource values apply to non-ANSI
        colors)
      • 
      
    
    
    • 

    
  • ptyx.h

      
      
        
    • added original_fg, original_bg to TScreen
        structure.
      • 
      
    
    
    • 

    
  • scrollbar.c

      
      
        
    • (compiler warnings: redundant cast)
      • 
      
    
    
    • 

    
  • util.c

      
      
        
    • new functions getXtermForeground and getXtermBackground
        replace the macros GET_FG and GET_BG, with the added
        functionality of checking for the reverse-video status of
        xterm.
      • 

        
    • in ReverseVideo, swap the SGR foreground and background
        colors also.

Patch #10 - 1996/2/14 -
  XFree86 3.1.2Cd


  
I observed an occasional glitch in the xterm's color behavior;
  a clear to end of line would get a color that had been used in a
  program that supposedly reset colors. I traced this down to the
  way xterm was modifying colors of GC's on the fly; it didn't
  restore the original color of the GC, even though it would later
  be used in functions (such as ClearRight) that assumed (my error)
  that the GC would have the current foreground or background
  color.


  
I fixed this by resetting the GC's colors with a new function
  'resetXtermGC()', and direct calls on
  SGR_Foreground/SGR_Background, as appropriate and using a new
  function 'updatedXtermGC()' to encapsulate the logic that
  modifies the GC's color. (I also removed some commented-out code
  that was trying to do this -- the problem was a little more
  obscure).


  
Patch #9 - 1996/2/10 -
  XFree86 3.1.2Cb


  
This patch fixes the remaining problems that I had making
  xterm run with x11r5, as well as a couple of other bugs. It
  follows my patch from yesterday, that added ifdef's for some of
  the input-method resources.


  
    
    
  • corrected ifdef's that suppress the input-method code
    (doesn't exist in my x11r5, and xterm works adequately without
    it).
    • 

    
  • corrected fallback definition for 'Select()' macro (oops:
    I'd copied the wrong text...)
    • 

    
  • moved the declarations for the fd_set variables to
    data.[ch]
    • 

    
  • corrected an ifdef in resize.c (sunos 4.x doesn't have
    termcap.h)
    • 

    
  • corrected (in main.c) some unused/orphaned variables.
    • 
  


  
Patch #8 - 1996/2/9 -
  XFree86 3.1.2Cb


  
This is mostly a documentation patch for xterm. It describes
  the color control sequences in more detail, and documents some
  other features of xterm that aren't described elsewhere.


  
I've also added a couple of ifdef's to fix (part of) the
  problem that I'm working on (making the program work properly on
  x11r5, where I'm doing memory testing -- I have a "good" version
  from mid-January, but my resync version doesn't work properly on
  x11r5). I'm not done with that yet.


  
Patch #7 - 1996/1/28 -
  XFree86 3.1.2n


  
I did a (clean) build of 3.1.2n on Linux 1.2.13 (ELF). I've
  got an S3 card.


  
This fixes the following in the 3.1.2n xterm:


  
    
    
  • initialize cur_foreground, cur_background in charproc.c
    (Purify told me they weren't initialized).
    • 

    
  • add interpretation of codes 39, 49, to reset background and
    foreground to default value (I'm told that ISO 6429 does this;
    but I don't have a written reference -- yet -- can anyone help
    here?). Anyway, rxvt does it, and it'll solve my remaining
    color management problems.
    • 

    
  • shadowing of 'time' in menu.c
    • 

    
  • 'Cardinal' vs 'int' in scrollbar.c
    • 

    
  • several changes to permit compile with X11R5 (the system
    that I've got Purify on won't be upgraded to X11R6 for a long
    time).
    • 
  


  
I built this version (with a minor nit that I'll patch soon)
  on SunOS 4.1.3 so that I can test it some more with Purify.


  
btw: the changes made in Xpoll.h won't work on some
  older systems, because fd_set isn't a defined type (I've got one
  machine at least that this applies to).


  
Patch #6 - 1996/1/8


  
This patch does all of the SGR foreground/background fixes
  (i.e., clearing the screen after an SGR color is set causes that
  color to be used in the foreground and/or background). If the
  FG_COLOR and/or BG_COLOR flags aren't set, then the xterm
  foreground and background default to the window's values. This
  usage is consistent with various types of hardware (especially
  the IBM PC), and is also used in rxvt.


  
    
    
  • charproc.c:

      
      
        
    • add/use new macros GET_FG, GET_BG - n/c.
      • 

        
    • add/use new functions SGR_Foreground() and
        SGR_Background() to set corresponding colors in GC's, and
        to retain sense of "original" colors.

          
      => This makes redundant some of the corresponding
          logic in HideCursor to set the foreground and background,
          but I left it in since it may be fixing an
          unrelated requirement.
      
        
      • 

        
    • set GC's in LoadNewFont() according to whether the SGR
        fg/bg colors are active.

          
      => This fixes some glitches in the accompanying
          resize, that leaves parts of the window in the original
          background color.
      
        
      • 
      
    
    
    • 

    
  • screen.c:

      
      
        
    • modified ClearBufRows() to use the SGR fg/bg colors if
        they're set.
      • 

        
    • added function ScrnClearLines(), used this to replace
        portions of ScrnInsertLine() and ScrnDeleteLine(). The new
        function uses the SGR fg/bg colors if they're set.

          
      => Otherwise, selection after an index or reverse
          index will paint the wrong colors.
      
        
      • 

        
    • modified ScrnDeleteChar() and ScrnInsertChar() to use
        SGR fg/bg colors.
      • 
      
    
    
    • 

    
  • util.c:

      
      
        
    • modified ClearRight() so that if either of the SGR
        fg/bg colors is set, we don't bzero the attributes and
        color arrays, but instead fill them with the appropriate
        codes.
      • 

        
    • modified ClearLeft to use SGR fg/bg colors.
      • 
      
    
    
    • 
  


  
Patch #5 - 1996/1/7


  
This patch modifies the object code, by replacing indexing
  expressions with temporary variables with the full indexing
  expression. At first glance, this seems inefficient (it did to me
  ;-), until remembering comments made in the compilers newsgroups
  that trying to "help" the compiler doesn't really work that well.
  A good optimizing compiler can do a better job than the
  programmer can. (There's a moral in the use of 'register'
  variables also, but I won't fix those...).


  
Anyway, the revised code generates a smaller object...


  
    
    
  • charproc.c:

      
      
        
    • recode index expressions in ShowCursor() and
        HideCursor() using SCRN_BUF_xxxxS macros - changes
        object.
      • 

        
    • replace constant '4' by MAX_PTRS - n/c.
      • 
      
    
    
    • 

    
  • ptyx.h:

      
      
        
    • defined the SCRN_BUF_xxxxS macros in terms of BUF_xxxxS
        macros, to pick up references to ScrnBuf data directly, and
        added MAX_PTRS symbol to pick up those '4' constants strewn
        about the code - n/c.
      • 
      
    
    
    • 

    
  • screen.c:

      
      
        
    • recode index expressions in ScreenWrite() using
        SCRN_BUF_xxxxS macros - changes object.
      • 

        
    • replace constant '4' by MAX_PTRS - n/c.
      • 

        
    • use macros BUF_CHARS, BUF_ATTRS - n/c.
      • 

        
    • cast calloc to 'Char *' to fix compiler warning on IRIX
        - n/c
      • 
      
    
    
    • 

    
  • scrollbar.c:

      
      
        
    • replace constant '4' by MAX_PTRS - n/c.
      • 

        
    • cast calloc to 'Char *' to fix compiler warning on IRIX

Patch #4 - 1996/1/7


  
When setting up for this phase, I saw that you'd corrected the
  bug that I found in ClearLeft. I decided to make this series of
  patches anyway, since readability never hurt (and there's the
  potential for finding another bug while reviewing this set).


  
    
    
  • button.c:

      
      
        
    • use SCRN_BUF_xxxxS macros - n/c
      • 
      
    
    
    • 

    
  • charproc.c:

      
      
        
    • use SCRN_BUF_xxxxS macros - n/c
      • 
      
    
    
    • 

    
  • ptyx.h:

      
      
        
    • added four macros: SCRN_BUF_CHARS, SCRN_BUF_ATTRS,
        SCRN_BUF_FORES, SCRN_BUF_BACKS to represent the four arrays
        that are derived from screen->buf.

    •

    • 
  


  
Patch #3 - 1996/1/7


  
This is my third (and final cleanup) patch for xterm. It gets
  rid of the unused stuff, and converts several functions to static
  (thereby reducing their scope).


  
At this point, the only compile warnings I've got (on Linux)
  are those about the select arguments (int vs fd_set type), and a
  missing declaration for waitpid. Those both are hard to get right
  without autoconfigure.


  
The next patches will address the functional changes...


  
    
    
  • Tekproc.c:

      
      
        
    • changed several functions to 'static' that aren't used
        outside this module -- changes object

    • 

    
  • main.c:

      
      
        
    • changed several functions to 'static' that aren't used
        outside this module -- changes object
      • 

        
    • ifdef'd out unused function 'consolepr()' -- changes
        object
      • 

        
    • removed unused variable 'dummy_tio' -- changes
        object
      • 

        
    • moved variable 'discipline' to quiet unused-warning --
        changes object
      • 
      
    
    
    • 

    
  • main.h:

      
      
        
    • deleted unused definition of DEFBORDERWIDTH - n/c
      • 
      
    
    
    • 

    
  • misc.c:

    • 
  


  
Patch #2 - 1996/1/7


  
This is my second patch to xterm. It corrects most of the gcc
  warnings (except for some that are due to X header files ;-). I
  compared objects to keep track of the changes that don't affect
  the object code (n/c) versus those that do.


  
At this point, I'm compiling (fairly) clean with gcc
  options

  
        -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wnested-externs



  
(I also compiled with -Wshadow, but while that found some
  things that I wanted to find, there's far too many warnings from
  the X headers to be usable in this context).


  
The changes:


  
    
    
  • Tekproc.c:

      
      
        
    • parenthesized expression to avoid gcc warning --
        n/c.
      • 

        
    • corrected nested-extern declaration for Bool
        waiting_for_initial_map; ourTopLevelShellArgs, and
        number_ourTopLevelShellArgs - n/c
      • 
      
    
    
    • 

    
  • charproc.c:

      
      
        
    • corrected potentially-unintialized variables 'scstype',
        'xim', and 'input_style' -- changes object.
      • 

        
    • adjusted logic of VTparse so that gcc won't warn about
        setjmp clobbering parsestate -- changes object.
      • 

        
    • corrected initialization of 'scstype', which could have
        been clobbered by setjmp/longjmp - changes object.
      • 

        
    • corrected nested-extern declaration of 'term',
        'ProgramName' - n/c
      • 
      
    
    
    • 

    
  • cursor.c:

      
      
        
    • corrected nested-extern declaration of 'term' --
        n/c
      • 

        
    • renamed 'term' parameters to avoid gcc -Wshadow warning
        - n/c
      • 
      
    
    
    • 

    
  • input.c:

      
      
        
    • change interface of StringInput to assume size_t (i.e.,
        unsigned) nbytes -- changes object.
      • 

        
    • change interface of funcvalue, and sunfuncvalue to use
        'KeySym' type instead of 'int' - changes object.
      • 
      
    
    
    • 

    
  • main.c:

      
      
        
    • moved definitions of SIGNAL_T, SIGNAL_RETURN to proto.h
        - n/c
      • 

        
    • corrected missing params of 'do_hangup()' -- changes
        object (note: the missing params were not used).
      • 

        
    • corrected missing param of 'Error()' -- changes
        object
      • 

        
    • corrected nested-extern 'environ' - n/c
      • 

        
    • adjusted assignments to 'tty_got_hung' and 'no_dev_tty'
        so that gcc can see they won't be clobbered by the longjmp
        - changes object.
      • 

        
    • use Size_t type - n/c.
      • 
      
    
    
    • 

    
  • menu.c:

      
      
        
    • removed redundant prototype for 'do_hangup()' --
        n/c.
      • 

        
    • renamed 'time' parameters to avoid gcc -Wshadow warning
        - n/c
      • 
      
    
    
    • 

    
  • menu.h:

      
      
        
    • renamed 'time' parameters to avoid gcc -Wshadow warning
        - n/c
      • 
      
    
    
    • 

    
  • misc.c:

      
      
        
    • corrected definition of 'HandleFocusChange()' --
        changes object
      • 

        
    • cast parameters in call to 'TekExpose()' -- n/c
      • 

        
    • corrected nested-extern declarations of 'term',
        'toplevel', ProgramName, and 'environ' -- n/c.
      • 

        
    • use Size_t type - n/c.
      • 
      
    
    
    • 

    
  • proto.h:

      
      
        
    • moved definition of SIGNAL_T (and SIGNAL_RETURN) here
        from main.c, resize.c to allow use of this symbol in
        prototypes (mostly in xterm.h).
      • 

        
    • added definition 'Size_t' to use as corrected type for
        strncpy, malloc sizes - n/c.
      • 
      
    
    
    • 

    
  • resize.c:

      
      
        
    • moved SIGNAL_T definition to proto.h -- n/c.
      • 

        
    • use Size_t type - n/c.
      • 
      
    
    
    • 

    
  • screen.c:

      
      
        
    • use Size_t type - n/c.
      •

        ANSI spec here). I used gcc -Wconversion to find these, but
        there's a lot of unrelated warnings that are due to setting
        NARROWPROTO in the config - n/c.

Patch #1 - 1996/1/6


  
This is my first cleanup patch for xterm. It addresses all of
  the gcc warnings for -Wall, -Wmissing-prototypes and
  -Wstrict-prototypes that I can change without modifying the
  object code. (I'm compiling this with gcc 2.7.0 for an aout
  target, which makes it simple to compare objects. When I do
  ELF-only, I've got a tool that compares that sort of thing as
  well).


  
Briefly, this patch adds (and uses) two header files in the
  xterm directory:

  
        proto.h
        xterm.h



  
I expect this to be the biggest patch by far. However (barring
  a misplaced prototype), it shouldn't break anything, since the
  intent of the patch is to provide missing declarations.

--------------------------------------------------------------------------------
                            Patch #330 - 2017/06/20

     * updates for ReGIS (Ross Combs):
          + remove redundant text command error check which broke T(B) and
            T(E).
          + retain  the  loading  alphabet  number across multiple “Lâ€
            commands.
          + add S(T) delay handler.
          + fix some color handling error messages.
          + add stubbed-out macrograph handling.
          + use  fragment_remaining()  and  fragment_consumed() instead of
            manually checking position / length in various places.
          + rename  some  local  variables  in  string  /  extent / option
            parsing
          + wrap some long lines.
          + move macrograph command handling out of the top-level.
     * add a summary of the italic fonts loaded to -report-fonts option.
     * modify the font-lookup for italics to allow for “-i-†if no match
       is found with slant “-o-†(prompted by patch by Ben Wong).
     * change  default values for mkSamplePass and mkSampleSize to reflect
       generally-improved  locale  support  in  various  operating systems
       (FreeBSD #219800).
     * modify  wcwidth.c to return -1 for non-Unicode values, and adjust a
       couple  of blocks to better match assumptions about ambiguous-width
       characters  in  other  implementations.  Also  modify  wcwidth.c to
       support  configurable soft-hyphen, so there is no drawback to using
       this version rather than a system wcwidth.
     * amend  change  made  in  patch #328 for cursor-visibility to handle
       case  where  an  application  is  updating  the reverse-video state
       (FreeBSD #219800).
     * update  tables  of  combining  and  ambiguous-width  characters  in
       wcwidth.c based on Unicode 10.0.0.
     * build-fix         for        --enable-sixel-graphics        without
       --enable-regis-graphics (reports by Sven Joachim, FreeBSD #219945).

#
# Special Capabilities:
# --------------------
# ich has a corresponding capability that inserts a single blank.  We could
#	have used ich1=\E[@, which works with ncurses, but that is not standard
#	behavior.  If it is set, then SVr4 vi (e.g., Solaris 2.6) emits both
#	smir/rmir and ich1.
# meml locks memory above the cursor; memu unlocks (ala HP terminals).  This
#	is not recognized by some older (e.g., SVr3) tic programs, but none
#	do more than warn about it.  Ignore the warning.
# smcup clears memory before switching to the alternate screen.  The older
#	(deprecated) \E[?47h did not do this, requiring applications to
#	embed a \E[2J in the rmcup string.  However, that behavior cannot
#	be disabled via titeInhibit, making that resource not function as
#	intended on systems with terminfo.
# rs2/is2 are shorter with XFree86 xterm because it supports DECSTR.  We
#	use the shorter sequence for compatibility with the termcap, which
#	is trimmed to keep it shorter than 1023 characters.  It (escape \E[!p)
#	replaces these in the conventional vt100 reset-string:
#		\E7	- save cursor (fixes origin-mode side-effect)
#		\E[r	- reset scrolling margins
#		\E[m	- reset SGR (including color)
#		\E[?7h	- reset wraparound mode (DECAWM)
#		\E[?1l	- reset application cursor keys (DECCKM)
#		\E[?6l	- reset origin mode (DECOM)
#		\E8	- restore cursor
#	DECSTR is recognized by XFree86 xterm even in vt52 mode.
#
# Editing Keypad:
# --------------
# XFree86 xterm emulates vt220 if the decTerminalID resource is set to 200 or
# higher.  Otherwise it emulates a vt100 or vt52 depending on the value of the
# resource.  When emulating a vt220, we support the editing keypad.  Sun and PC
# keyboards have an editing keypad which is similar to the vt220:
#
#	VT220 editing keypad
#	----------------------------
#	Find      Insert      Remove
#	Select    Prev        Next
#	----------------------------
#
#	Sun/PC editing keypad
#	----------------------------
#	Insert    Home        PageUp
#	Delete    End         PageDn
#	----------------------------
#
# If the sunKeyboard resource is true, we map it this way (adjusting the values
# of Home, End and Delete):
#	VT220		      Sun/PC
#	----------------------------
#	Find		      Home
#	Select		      End
#	Insert		      Insert
#	Remove		      Delete
#	Prev		      PageUp
#	Next		      PageDn
#	----------------------------
#
# Note that all of the keys on the editing keypad transmit escape sequences.  A
# vt220 does this only when in vt220 mode; when emulating a vt100 the editing
# keypad is inactive.
#
# Alternative keycodes:
# --------------------
# Several of the function keys have alternative names, depending on the type of
# host which your xterm is connected to.  DEC (i.e., the VMS system) uses F15
# as the HELP key, F16 as the DO key.  Unix applications generally do not do
# this.  Curses applications in particular, assign a unique keycode to each
# capability string.  These terminal descriptions do not have conflicting
# definitions, to ensure that Unix curses applications use a consistent set of
# keycodes.  To get a VMS-bias, make these substitutions:
#	1. change khome to kfnd
#	2. change kend to kslt
# The original xterm-r6 entry does in fact have a VMS bias.
#
# Some legacy applications using the termcap emulation may expect kll where
# we have specified kend.
#
# Function keys with modifiers (Sun/PC):
# -------------------------------------
#	Shift-Fx          - kf{12+x}
#	Control-Fx        - kf{24+x}
#	Shift-Control-Fx  - kf{36+x}
#
# The terminfo defines some special keys which are documented as "shifted",
# e.g., kDC is shifted-delete-character.
#
# Note however, that even though the terminfo says a key might be sent, there
# may be conflicts which prevent this.  For example, it is common to use
# shifted pageup and pagedown for window manager functions.  The default
# translation for xterm since X11R4 has overridden shifted Insert, Select,
# PageUp and PageDown, which correspond to terminfo kIC, kEND, kPRV and kNXT
# respectively.

#
# Some names are extensions allowed by ncurses, e.g.,
#	kDN, kDN5, kDN6, kLFT5, kLFT6, kRIT5, kRIT6, kUP, kUP5, kUP6
#
# The uppercase names are made up, since there are no standards that apply.
# If they were limited to two characters, they could in principle be translated
# to termcap.  However, termcap sizes are limited to 1023 bytes, so there is
# little point in ensuring that extended key names can be translated to
# termcap.  A terminfo file can be up to 4096 bytes; using all extended keys
# that xterm can generate would in fact exceed that limit.
#
# The numbers correspond to the modifier parameters documented in Xterm
# Control Sequences:
#
#	2	Shift
#	3	Alt
#	4	Shift + Alt
#	5	Control
#	6	Shift + Control
#	7	Alt + Control
#	8	Shift + Alt + Control
#
# X/Open Curses defines some shift combinations, which are also used here
# where applicable.  Since it does define some shift combinations, no number
# (2) is used for suffixing the made-up names.  Some combinations are not
# useful, e.g., they may reboot your computer, or they may require too many
# fingers.  I stopped at modifier 7, just to keep things simple -TD
#
# XTerm resources:
# ---------------
# The xterm+pcfn, xterm+pcf0, xterm+pcf1, xterm+pcf2 and xterm+pcf3 fragments
# correspond to default resource settings for xterm on a 104-key PC keyboard
# with 12 function-keys:
#
#	*sunKeyboard:false
#	*oldXtermFKeys:false
#	*modifyCursorKeys:2
#	*modifyFunctionKeys:2
#	*ctrlFKeys:10
#
# The key numbers are computed based on the modifiers:
#
#	kf1-kf12 are F1-F12
#	kf13-kf24 are shift F1-F12
#	kf25-kf36 are control F1-F12
#	kf37-kf48 are control+shift F1-F12
#	kf49-kf60 are alt F1-F12
#	kf61-kf63 are shift-alt F1-F3
#
# Note that ncurses would allow definition of kf64 and beyond, if there were
# an application that required it.

# This chunk is based on suggestions by Ailin Nemui and Nicholas Marriott, who
# asked for some of xterm's advanced features to be added to its terminfo
# entry.  It defines extended capabilities not found in standard terminfo or
# termcap.  These are useful in tmux, for instance, hence the name.
#
# One caveat in adding extended capabilities in ncurses is that if the names
# are longer than two characters, then they will not be visible through the
# termcap interface.
#
# Ms modifies the selection/clipboard.  Its parameters are
#	p1 = the storage unit (clipboard, selection or cut buffer)
#	p2 = the base64-encoded clipboard content.
# 
# Ss is used to set the cursor style as described by the DECSCUSR
#	function to a block or underline.
# Se resets the cursor style to the terminal power-on default.
#  
# Cs and Ce set and reset the cursor colour.

#
# The "PC-style" modifier scheme was introduced in xterm patch #94 (1999/3/27)
# and revised in patch #167 (2002/8/24).
#
# The original assignments from patch #94 for cursor-keys had some technical
# issues:
#
#	A parameter for a function-key to represent a modifier is just more
#	bits.  But for a cursor-key it may change the behavior of the
#	application.  For instance, emacs decodes the first parameter of a
#	cursor-key as a repeat count.
#
#	A parameterized string should (really) not begin with SS3 (\EO).
#	Rather, CSI (\E[) should be used.
#
# For these reasons, the original assignments were deprecated.  For
# compatibility reasons, they are still available as a setting of xterm's
# modifyCursorKeys resource.  These fragments list the modified cursor-keys
# that might apply to xterm+pcfkeys with different values of that resource.

# Sun does not number the function keys this way in their sparse termcap; their
# terminal descriptions ignore the keypads.  kb(7M) states that there are codes
# reserved for 64 function keys, 16 each in left, right, top and bottom.  Each
# keyboard type has a different number of function keys in different
# arrangements.  Using xkeycaps for reference:
#
# Type 3:  left 10, top 9, right 15
# ------
# kf1-kf9 are XK_F1-XK_F9
# There is no kf10 on this keyboard type.
# kf11-kf20 are keysyms XK_L1 through XK_L10.
# kf31-kf45 are keysyms XK_R1 through XK_R15.
#
# However, X's keysymdef.h is hard-coded to make
#	XK_L1==XK_F11 and
#	XK_R1==XK_F21,
# by someone who was unfamiliar with terminal types other than Sun's.  So
# xterm uses the internal X keysymbols, but the terminfo entry uses the Sun
# numbering scheme.
#
# Type 4:  left 11, top 12, right 15
# ------
# The left-keypad contains an unnumbered Help-key.
# The right-keypad also contains NumLock, Ins, Del, Enter, + and - keys which
# do not appear to be part of the R-sequence.
#
# Type 5:  left 9, top 12, right (more than one keypad)
# ------
# These keyboards do not use the same naming convention, look like a hybrid of
# the type 4 and IBM keyboards.
#
# XTerm resources:
# ---------------
# Set the modifyFunctionKeys resource to negative (-1) to make it simple to
# enter the higher function-key values using shift- and control-modifiers.

# VTxxx terminals are usually set up so that full-screen applications will use
# the cursor application mode strings.  This is good for full-screen
# applications, including legacy applications which may have hard-coded
# behavior, but bad for interactive shells (e.g., tcsh, bash) which use arrow
# keys to scroll through a history of command strings.
#
# To see the difference between normal/application modes, consider this example:
#	+ In normal (non-application) mode, the terminal transmits a down-arrow
#	  as \E[C, which happens to echo as a down-arrow.
#	+ In application mode the terminal transmits \EOC, which echoes as C.
#	  That is because the \EO is the SS3 control, which says to use the
#	  character from the G3 character set for the next cell.
#
# One example of hard-coded behavior would be for applications written to work
# with VT52 and VT100 terminals.  If the application's parser ignores 'O' and
# '?' characters after the escape, then the cursor and keypad strings for the
# two terminals are the same.  (Indeed, one of the first curses applications
# which I used did something like this to cover "ANSI" terminals -TD).
#
# To make this work (leaving the cursor keys in normal mode), we have to adjust
# the terminal initialization sequences:
#
#	smkx/rmkx set/reset the cursor and keypad application modes.  We retain
#		the latter (otherwise many applications fail).
#
#	smcup/rmcup set/restore cursor-addressing mode for full-screen
#		applications.  For xterm, this normally means the alternate
#		screen, which is not compatible with interactive shells.  Some
#		programs are "smart" and disable these.

# Compatible with the R5 xterm, with the following changes:

#	+ changed kf1 through kf4 to correspond with actual usage.  Though X
#	  supports keypad symbols for PF1 to PF4, and xterm interprets these
#	  correctly, the F1 to F4 codes are commonly (but incorrectly) used.
#	+ moved reset string from rs1 to rs2, to correlate better with termcap.
#	+ make khome consistent with other entries.
#	+ use rmul/smul, rmir/smir from termcap, but not rmcup/smcup because
#	  not everyone wants the alternate screen.
#	+ added u6, u7, u8, u9 strings for Daniel Weaver's tack program.

 * This module contains the VMS version of the routine SPAWN (from the module

 *
 * Modification History:
 * Stephan Jansen 1-Mar-1990  Original version
 * Hal R. Brand   5-Sep-1990  Added code to propagate DECW$DISPLAY
 * Aaron Leonard 11-Sep-1990  Fix string descriptor lengths
 * Stephan Jansen 2-Dec-1991  Modify to use new Pseudo terminal drivers
 *                            (patterned after photo.c by Forrest A. Kenney)
 * Patrick Mahan  7-Jan-1991  Removed reference to  from VMS.C
 *			      Forced device type to be VT102 since that is
 *			      what we are emulating.

  XTerm
  Terminal emulator for the X Window System
  
    

   XTerm is the standard terminal emulator for the X Window System.
   It provides DEC VT102/VT220 and selected features from higher-level
   terminals such as VT320/VT420/VT520 (VTxxx).  It also provides Tektronix
   4014 emulation for programs that cannot use the window system directly.
  

    

   You would use xterm to get a shell prompt, to run command-line programs.

# These are termcap entries that correspond to xterm's terminfo file.
# The file is formatted using ncurses' "tic -CNx", but is not mechanically

#
# Note:
#	termcap format is limited to 1023 characters.  This set of descriptions
#	is a subset of the terminfo, since not all features can be fit into
#	that limit.  The 'xterm' description supports color.  The monochrome
#	'xterm-mono' drops color in favor of additional function keys.  If you
#	need both, use terminfo.
#
#	The 1023-character limit applies to each entry after resolving the
#	"tc=" strings.  Some implementations may discount all or part of the
#	formatting characters in the entry (i.e., the backslash newline tab
#	colon).  GNU termcap does not have this limit.
#
#	I checked the limits using ncurses "captoinfo -CrTUvx", which prints
#	the resolved length of each entry in a comment at the end - T.Dickey

     * I'm going to try to explain, as I understand it, why we
     * have to do XGetWMNormalHints and XSetWMNormalHints here,
     * although I can't guarantee that I've got it right.
     *
     * In a correctly written toolkit program, the Shell widget
     * parses the user supplied geometry argument.  However,
     * because of the way xterm does things, the VT100 widget does
     * the parsing of the geometry option, not the Shell widget.
     * The result of this is that the Shell widget doesn't set the
     * correct window manager hints, and doesn't know that the
     * user has specified a geometry.
     *
     * The XtVaSetValues call below tells the Shell widget to
     * change its hints.  However, since it's confused about the
     * hints to begin with, it doesn't get them all right when it
     * does the SetValues -- it undoes some of what the VT100
     * widget did when it originally set the hints.
     *
     * To fix this, we do the following:
     *
     * 1. Get the sizehints directly from the window, going around
     *    the (confused) shell widget.
     * 2. Call XtVaSetValues to let the shell widget know which
     *    hints have changed.  Note that this may not even be
     *    necessary, since we're going to right ahead after that
     *    and set the hints ourselves, but it's good to put it
     *    here anyway, so that when we finally do fix the code so
     *    that the Shell does the right thing with hints, we
     *    already have the XtVaSetValues in place.
     * 3. We set the sizehints directly, this fixing up whatever
     *    damage was done by the Shell widget during the
     *    XtVaSetValues.
     *
     * Gross, huh?
     *
     * The correct fix is to redo VTRealize, VTInitialize and
     * VTSetValues so that font processing happens early enough to
     * give back responsibility for the size hints to the Shell.
     *
     * Someday, we hope to have time to do this.  Someday, we hope
     * to have time to completely rewrite xterm.

27-JAN-2000.  Discovered a bug when doing an X11 paste into an EDT session,
had to add a tt_start_read() in button.c after the paste to reenable the
read AST.  Rearranged code in VMS.C to make the compiler happy and 
eliminate warnings.
