Faculty and staff advisors, being already fairly familiar with their courses and programs, often do not appreciate how inconvenient it is for students to access all the information they need to make course choices. For example, program requirements are typically specified as lists of course codes for required and optional courses; one must look elsewhere to find the titles of the courses, the relations between them, their prerequisites, and the timetabling information. As another example, a course description in a calendar typically specifies what the prerequisite courses are, but hardly ever specifies which course or courses the course is prerequisite to. This information may be very important to a student, but to discover it, he or she must search through all the subsequent course descriptions in the calendar. With a prerequisite chart, it is evident at a glance. As a third example, consider a student who wants to know whether they can defer a course till the following year without risk of timetable conflicts. With conventional sources of information, such a question can be answered only by doing an exhaustive search through both timetable and calendar for a possible conflict. A prerequisite chart incorporating timetable data provides the necessary information in a compact and usable form, and the question can be answered immediately. \subsubsection*{If prerequisite charts are so great, why doesn't every university department have them?} Few academic departments have the resources to produce prerequisite charts. If one searches on the web for "prerequisite chart" or "prerequisite diagram," virtually all of the matches are from departments that one would expect to have expertise in technical drawings. Here are some of these: \begin{itemize} \item Queen's University, Electrical and Computer Engineering\footnote{% \myurl{http://www.ece.queensu.ca/Current-Students/Undergraduate/files/Queens_ECE_prerequisite_graph_2011.pdf}} \item University of Waterloo, Computer Science\footnote{% \myurl{http://www.cs.uwaterloo.ca/current/courses/charts/majorPrereq.shtml}} \item Georgia Tech, Electrical Engineering\footnote{% \myurl{http://www.ece.gatech.edu/academics/undergrad/ee_prereq.html}} \item Georgia State University, Computer Science\footnote{% \myurl{http://www.cs.gsu.edu/sites/default/files/prereq.pdf}} \item Iowa State University, Civil, Construction, \& Environmental Engineering\footnote{% \myurl{http://www.ccee.iastate.edu/fileadmin/www.ccee.iastate.edu/academics/mechanical-prereq-0507.pdf}} \item Kansas State University, Mathematics\footnote{% \myurl{http://www.math.ksu.edu/courses/catalog/prereqcht.pdf}} \item Carleton University, Engineering Physics\footnote{% \myurl{http://www1.carleton.ca/engineering-design/ccms/wp-content/ccms-files/Engineering-Physics_Aug_19_11.pdf}} \end{itemize} \subsection{Prerex-Formatted Prerequisite Charts} \subsubsection*{Where can I see prerex-formatted charts in use?} There are several charts for both specialized and multi-disciplinary programs on-line here: \myurl{http://www.cs.queensu.ca/undergraduate/prerequisites}. \subsubsection*{What file formats are used for prerex-formatted charts?} The charts themselves are best distributed in the Portable Document Format (PDF) defined by Adobe; PDFs are readable on any platform and in most browsers using freely-available software (such as the Adobe Reader), printable on any high-resolution printer, relatively compact, and scalable to accommodate paper size, display resolution, or user preference. Charts can also be converted to Portable Network Graphics (PNG) format for in-line use on a web page. PNG format is also relatively compact and can be rendered directly by most web browsers. Prerex-formatted charts are produced by software that processes simple and convenient text-based descriptions. These descriptions can be edited in any text editor or in the \texttt{prerex} interactive editor discussed in Section~\ref{editor}. The format of chart descriptions is documented in Section~\ref{source}. \subsubsection*{What software is needed to produce prerex-formatted prerequisite charts?} To process the description of a prerex-formatted chart, the following software is essential: \begin{itemize} \item an up-to-date standard-conforming implementation of \LaTeX, a powerful document processing system based on \TeX, a professional-quality typesetting engine; see Section~\ref{installing}. \item a few additional \LaTeX\ packages, such as \texttt{pgf}, that may not be included in a minimal \LaTeX\ installation; see Section~\ref{additional}; \item a file \texttt{prerex.sty} of specialized \LaTeX\ definitions, which is included in the prerex package available at any repository of the Comprehensive TeX Archive Network (CTAN)\footnote{% \myurl{http://www.ctan.org/}}. \end{itemize} The following additional software is optional but recommended: \begin{itemize} \item a PDF viewer that \begin{itemize} \item can be configured to ``watch'' the PDF file so that it re-loads automatically when this is updated, and \item shows hyperlinks in a ``tooltip'' when the mouse hovers over it, which is a convenient way to get the coordinates of course boxes and arrows while editing the description; \end{itemize} see Section~\ref{PDF}. \item suitable fonts; see Section~\ref{fonts}. \item the \texttt{prerex} interactive editor for prerex-formatted charts; see Section~\ref{editor}. \item an integrated \LaTeX\ development environment; see Section~\ref{IDE}. \end{itemize} \subsubsection*{Why couldn't I use a program like Visio\textsuperscript{\textregistered}\ or CorelDRAW\textsuperscript{\textregistered}\ to produce a prerequisite chart?} You could, if you have such a program available, are very skilled in its use, and won't be embarrassed distributing a chart that looks amateurish. Look carefully at a prerex-formatted chart and notice the following properties: \begin{itemize} \item Each course box is sized to just enclose the text within it, with uniform standard margins. \item Each arrow between courses is oriented from box centre to box centre, rather than from/to standard "connection points" on the box edges. \item The arrows are "clipped" by the course boxes, but the arrow heads abut the target box exactly. \end{itemize} These desirable properties are not easily achieved using conventional ``do-it-yourself'' drawing software, no matter how ``user-friendly'' it purports to be. The prerex system provides complete flexibility as well as professional quality: \begin{itemize} \item Text within a course box may be partitioned into regions with varying characteristics. For example, the course code and the timetable information on the first line of course boxes are in a smaller font than the course name. The latter is centered and the former are left- and right-justified, respectively. Arbitrary \LaTeX\ formatting can be used for the text. \item Any available Type 1 (Postscript) or TrueType format fonts may be used; in the chart in Figure~\ref{chart}, the typeface used is Optima, an elegant \emph{sans serif} face designed by Hermann Zapf. The professional-quality typesetting engine takes advantage of kerns and ligatures in the fonts. \item Line thickness for boxes may be varied; in the example diagram, heavier boxes (and bold-face text) are used to indicate that a course is "required" in the program, rather than an option. \item Different styles of connectors can be used, for example to distinguish prerequisites, co-requisites, and recommended prerequisites. \item Various sizes or shapes of course boxes may be used, for example to distinguish between half and full courses. \item Graphic images such as logos can be imported. \item Colours and hyperlinks to on-line course descriptions or calendars are possible. \end{itemize} \subsubsection*{Wouldn't a commercial drafting service be able to produce a professional-looking prerequisite chart?} Possibly, but you will almost certainly have to do the global lay-out yourself. A more serious long-term problem is that it is unlikely you will be able to maintain the chart yourself using freely available software. You will be "locked-in" to use the drafting service for every future modification of the chart. If you want the quality and maintainability of a prerex-formatted chart but don't think you can produce it yourself, you can outsource the production; check out the following: \myurl{http://www.prerex.com}. \subsubsection*{How can a prerex-formatted chart be edited?} University programs and timetables change frequently: courses are added or dropped, pre- or co-requisites or timetabling of courses change, and so on. Use of a separate text-based description file and intelligent processing software make it easy to modify a prerex-formatted chart. If the text within a course box is changed, the size of the box, the length of connectors to and from that box, and the location of arrowheads into the box are all adjusted automatically by the processing software. If a course box must be moved, it is straightforward to edit the relevant instructions for arrows into or from the box because the coordinates specified for an arrow are those of the box centres, rather than those of the edges or corners of the boxes. Small changes can be made with any text editor. For creating a prerex-formatted chart or for making substantial changes to an existing chart, the \texttt{prerex} interactive chart editor and the graphical ``wrapper'' \texttt{vprerex} are available; see Section~\ref{editor}. Editing a text file in either of these ways is far easier and faster than trying to fiddle with an image using a mouse. \section{Viewing and Printing a Prerequisite Chart} \label{PDF} A prerequisite chart in Portable Document Format (PDF) can be ``opened'' for viewing or printing in any PDF viewer. The most popular of these is the Adobe Reader.\footnote{\myurl{http://www.adobe.com/prodindex/acrobat/readstep2.html}} However, the Adobe Reader is quite slow to load and somewhat inconvenient to use if one wants to re-load the document after changing it (normally one must first close the document and then re-open it). There are faster and more convenient alternatives to the Adobe Reader. One that is available for Windows, Macs, and Linux systems is a ghostscript-based viewer called GSview.\footnote{% \myurl{http://www.cs.wisc.edu/~ghost/}} For Windows or Linux: download and install the most recent version of ghostscript for your platform,\footnote{% \myurl{http://www.cs.wisc.edu/~ghost/doc/AFPL/index.htm}} and then install the most recent version of GSview for your platform.\footnote{% \myurl{http://www.cs.wisc.edu/~ghost/gsview/index.htm}} For Macs: just get MacGSView.\footnote{% \myurl{http://www.cs.wisc.edu/~ghost/macos/index.htm}} For Linux systems, other ghostscript-based viewers such as \texttt{gv}\footnote{% \myurl{http://wino.physik.uni-mainz.de/~plass/gv/}} are available. Also, \texttt{xpdf}\footnote{% \myurl{http://www.foolabs.com/xpdf/home.html}} is suitable for any X-window based systems, such as any version of Linux. If Gnome or KDE libraries are installed, variants \texttt{gpdf}, \texttt{kghostview}, \texttt{evince}, and \texttt{kpdf} (now renamed \texttt{okular}) of these programs are available. You may print a prerequisite chart from within any of these viewing applications. If you are \emph{editing} a prerequisite chart (using either a text editor on the chart description or the \texttt{prerex} editor), you will want to use a PDF viewer that not only can be configured to ``watch'' the PDF file (so that it re-loads automatically when this is updated), but also shows hyperlinks in a ``tooltip'' when the mouse hovers over it; this is a convenient way to get the coordinates of course boxes and arrows while editing the description. Recent versions of some of these viewing programs have the latter capability. The \texttt{vprerex} ``wrapper'' for the \texttt{prerex} editor includes a built-in \texttt{prerex}-enabled PDF viewer that makes it extremely easy to transfer coordinates from the chart to the editor. \section{Installing a Basic \LaTeX\ System} \label{installing} To ``process'' a chart description, you will need to install an application called \LaTeX, together with several auxiliary applications to convert the output into Postscript and then PDF. \LaTeX\ is a powerful document processor based on a professional-quality typesetting program called \TeX. The following web sites will point you to as much information as you might want on \LaTeX\ and \TeX: \begin{itemize} \item \LaTeX\ Project home page\footnote{\myurl{http://www.latex-project.org}} \item \TeX\ Users Group home page\footnote{\myurl{http://www.tug.org/}} \item \TeX\ FAQ\footnote{\myurl{http://www.tex.ac.uk/cgi-bin/texfaq2html}} \end{itemize} If you use Windows, we suggest you install the ``basic'' version of MiKTeX.\footnote{% \myurl{http://www.miktex.org/setup.html}} If you use Mac~OS~X, go to the \emph{\TeX\ on Mac OS~X} site.\footnote{% \myurl{http://www.rna.nl/tex.html}} Unix and Linux users should install \texttt{texlive}.\footnote{% \myurl{http://www.tug.org/texlive/}} The resulting installation will allow you to process simple \texttt{.tex} files. However, you won't be able to process the description of a prerex-formatted prerequisite chart until some necessary additional software is installed. \section{Additional \LaTeX\ Software} \label{additional} To process descriptions of prerex-formatted charts, some additional packages are needed. The file \texttt{prerex.sty} is essential; it should be stored in the same folder as the \texttt{.tex} file to be processed (or in the local \verb|texmf| tree) so the \LaTeX\ system can find it. Other add-ons that may be necessary are as follows: \texttt{pgf}, \texttt{tikz}, \texttt{multido}, \texttt{textcomp}, and \texttt{xcolor}. If you are using \MikTeX\ or \texttt{texlive}, these can be installed using the package manager. All of the packages are also available for download from any CTAN\footnote{% \myurl{http://www.ctan.org/}} repository. You are now ready to process the description for a chart. Get a command-line prompt, move to the folder with the chart description and issue the following instruction: \begin{verbatim} pdflatex chart \end{verbatim} This operation will overwrite any existing \verb|chart.pdf|, so you should first re-name that file if you want to preserve it. If the \texttt{pdflatex} command isn't recognized, you will have to edit the system executable-command path. On a Unix-like system, adjust the value of \texttt{PATH}; on Windows, click on \emph{Control~Panel} $\rightarrow$ \emph{System} $\rightarrow$ \emph{Advanced} $\rightarrow$ \emph{Environment~Variables}, select \emph{Path} and click on \emph{Edit}; then append the appropriate paths, separated by semi-colons. For \MikTeX, the default path for commands is \verb|C:\texmf\miktex\bin|. \section{Installing a \LaTeX\ Development Environment} \label{IDE} Most beginning users will prefer to use a graphical ``development environment'' which supports editing, processing and previewing of documents, rather than the command-line interface. There are \emph{many} such applications. For Windows, we suggest you go the Texmaker download site\footnote{% \myurl{http://www.xm1math.net/texmaker/download.html}} and click on the link for the self-installing archive \verb|texmakerwin32_install.exe|. For Mac OS~X, go to the same site, get the \texttt{texmakerbinmacosx} archive and follow the instructions. For Linux, install a \texttt{texmaker} package or get the source files at the Texmaker site. When Texmaker has been installed, start it up and then click on \emph{Options} $\rightarrow$ \emph{Configure~Texmaker} to do any necessary configuration, such as the \emph{Quick Build} operation. You should now be able to open the source file for your chart, process it, and then view the result using the items in the \emph{Tools} menu, or the \emph{Quick~Build} button. If there are any processing errors, error messages will appear in the bottom window pane. Many other LaTeX editors are available if Texmaker doesn't satisfy you. Two of the most popular of these for Windows are WinEdt\footnote{% \myurl{http://www.winedt.com/}} and TeXnicCenter;\footnote{% \myurl{http://sourceforge.net/projects/texniccenter}} the former is ``shareware'' and the latter is free. Mac users may want to check out the list of ``front-ends'' at the \emph{TeX on Mac OS~X} site.\footnote{% \myurl{http://www.rna.nl/tex.html}}. Linux users also have Kile\footnote{% \myurl{http://kile.sourceforge.net/}} and Klat.\footnote{% \myurl{http://research.edm.luc.ac.be/jori/klat/klat.html}} \section{Fonts} \label{fonts} Look carefully at the samples in Figure~\ref{samples}. \begin{figure} \centering \includegraphics*[scale=0.35]{introFonts} \caption{Typeface Samples} \label{samples} \end{figure} Times and Palatino are \emph{serifed} typefaces; the serifs are the small projections at the baselines, and sometimes at the tops, of characters. Serifs improve the readability of \emph{long} texts. The others are \emph{sans serif} typefaces; this class of typefaces is more appropriate for use in prerequisite charts where \emph{legibility} of fairly small and short textual fragments is of primary importance. Computer Modern Sans is the default \emph{sans serif} font in \LaTeX, and Helvetica and Avant~Garde should also be available in every \LaTeX\ installation. To get Helvetica (scaled down 20\%) or Avant Garde, use \begin{verbatim} \usepackage[scaled=0.8]{helvet} \end{verbatim} or \begin{verbatim} \renewcommand{\sfdefault}{pag} \end{verbatim} respectively. If none of these is used, (or the command is commented out by preceding it with a \verb|%| character), Computer Modern Sans will be used. Futura, Gill Sans, Frutiger and Optima are commercial fonts available from font vendors such as \texttt{myfonts.com}. The \LaTeX\ support files and instructions for installation into a standard \LaTeX\ implementation for many commercial fonts can be found at CTAN\footnote{% \myurl{http://www.ctan.org/tex-archive/fonts/psfonts/w-a-schmidt/}}; otherwise you will have to follow the instructions in the Font Installation Guide\footnote{% \myurl{http://www.ctan.org/tex-archive/info/Type1fonts/fontinstallationguide/}} Less expensive alternatives may be available to you. The Humanist~521 and Zapf-Humanist~601 families of fonts are Bitstream clones of Gill Sans and Optima, respectively. These fonts are available from commercial vendors but have been bundled with Corel applications such as \mbox{WordPerfect}, and so you may already have them. Windows\textsuperscript{\textregistered}\ systems come with several fonts, some of which might be suitable for use in prerequisite charts. Four URW-Classico fonts, a fairly good clone of Optima, are available in a package of 79~fonts in Type~1 format that may be legally downloaded for non-commercial use from Artifex\footnote{% \myurl{http://www.artifex.com/downloads/}}. The four Classico font files, renamed for use in \LaTeX, with the necessary support files and installation instructions are available from CTAN\footnote{% \myurl{ftp://tug.ctan.org/pub/tex-archive/nonfree/fonts/urw/classico.zip}}. Note that the font files cannot be distributed commercially without a commercial license; please read the license in the archive before re-distributing them. This restriction does not prevent you from distributing documents that \emph{use} the fonts. \section{Conversion to Portable Network Graphic (PNG) Format} Although PDF is currently the best available format for distributing and printing charts, you may want to produce a raster-image version for use on a web site. There are several conversion programs and services available to do this. For example, the \verb|convert| tool of the multi-platform \verb|ImageMagick|\footnote{% \myurl{http://www.imagemagick.org/}} package may be used as follows: \begin{verbatim} convert -density 125 -quality 100 chart.pdf chart.png \end{verbatim} The density parameter specifies the number of pixels per inch; if this is too small, the image is of poor quality, and if it is too large, the image file is too big. The quality parameter ensures maximal (loss-free) compression. From version 5.0, \verb|prerex.sty| generates an auxiliary file containing image-map data for the hyperlinked nodes in the chart; consult a reference on the HTML language for an explanation of (client-side) image maps. \section{Terminology and Coordinate System} Before we discuss the \texttt{prerex} editor and the format of ``source files'' (i.e.,~chart descriptions), we shall summarize the necessary terminology and coordinate conventions. A prerequisite chart consists of a number of \emph{course boxes}, linked by \emph{arrows}. Courses are either \emph{half} or \emph{full}, and may be \emph{required}. Each course box can contain a course \emph{code} (upper left corner), a course \emph{title} (lower half), and \emph{timetable} information (upper right corner). An arrow can be either a \emph{prerequisite} (solid), a \emph{co-requisite} (dotted), or \emph{recommended} (dashed). When a conventional arrow would be inappropriate, it is possible to use a \emph{mini} course ``box'' (consisting of just a course code) just above a target box. A line (or paragraph) of text may be placed anywhere on the chart. A conventional two-dimensional Cartesian coordinate system is used to specify the locations of diagram elements. The origin (where $x = 0$ and $y = 0$) is at the lower-left corner of the diagram. The diagram height is configurable; the width is determined by the values of the \LaTeX\ length \verb|\textwidth| and an adjustable \verb|\unit| length, which defines the absolute value of a coordinate unit. It is possible to put a coordinate grid with labelled axes in the background of a chart. The coordinates of a \emph{box,} \emph{mini, or \emph{text-line}} are those of its centre point. An \emph{arrow} is described by the coordinates of the centre points of its source and target boxes/minis/text-lines. \section{Chart Editing} \label{editor} The source code of \texttt{prerex}, an interactive (command-line) prerequisite-chart editor, is available at CTAN repositories.\footnote{\myurl{http://www.ctan.org/tex-archive/graphics/prerex/}} It should build on any \textsc{Unix}-like system with suitable tools and libraries installed; for example, it can be compiled on GNU/Linux, Solaris, the Cygwin\footnote{\myurl{http://www.cygwin.com/}} platform on Windows, and the Fink\footnote{\myurl{http://fink.sourceforge.net/}} platform on OS~X, if the GNU \texttt{readline} library is installed. The editor supports add, remove, cut-and-paste, and edit operations on course boxes, minis, text-lines, and arrows, and shifts of specified diagram elements or an entire diagram. A summary of all commands supported by \texttt{prerex} is given in Table~\ref{help} on page~\pageref{help}. Note that if a course box/mini/text-line is ``cut'' and then ``pasted'' elsewhere, the target or source coordinates of arrows into or out of the source and target are adjusted accordingly, and similarly if nodes are shifted or raised. To allow permutations of two or more chart elements, the editor maintains a ``stack'' of elements that have been cut but not yet pasted. The notation $x_0,y_0:x_1,y_1$ denotes all the nodes (course boxes, minis, texts) in the rectangle whose northwest and southeast corners are at coordinates $x_0,y_0$ and $x_1,y_1$. \begin{table} \begin{center}\small \begin{tabular}{|l|l|} \hline \multicolumn{1}{|c|}{\textbf{Command}} & \multicolumn{1}{|c|}{\textbf{Effect}} \\ \hline\hline \verb\file> box x,y \ & [create and] edit course box at $x,y$\\ \verb\file> mini x,y \ & [create and] edit mini course at $x,y$\\ \verb\file> text x,y \ & [create and] edit text centered at $x,y$\\ \verb\file> arrow x0,y0,x1,y1\ & [create and] edit arrow from $x0,y0$ to $x1,y1$\\ \verb\file> cut x,y ... \ & (temporarily) remove box, mini, or text at $x,y$\\ \verb\file> paste x,y \ & re-insert removed box, mini, or text at $x,y$\\ \verb\file> delete [x,y | x0,y0,x1,y1 | x0,y0:x1,y1] ...\ & remove specified elements/arrows\\ \verb\file> shift [-]x x0,y0[:x1,y1] ...\ & move [specified] elements $x$ units right [left]\\ \verb\file> raise [-]y x0,y0[:x1,y1] ...\ & move [specified] elements $y$ units up [down]\\ \verb\file> undo \ & undo the effect of the previous editing command\\ \verb\file> write | ! \ & save to \verb\file\ and process (with \verb\pdflatex)\\\ \verb\file> quit | exit | x | ^D\& turn off grid, save to \verb\file\, process, and exit\\ \verb\file> !cmd \ & execute shell command \verb\cmd\, then reload\\ \verb\file> Backup \ & copy \verb\file\ to \verb\.file\\\ \verb\file> Restore \ & restore from \verb\.file\\\ \verb\file> grid [y/n] \ & turn on/off coordinate grid background\\ \verb\file> help | ? \ & print this summary\\ \hline \end{tabular} \end{center} \caption{\texttt{prerex} Command Summary (version 6.3)} \label{help} \end{table} The effects of editing operations may be observed in a PDF viewer. See the manual page \texttt{prerex(1)} for more information. The \texttt{prerex} package at CTAN also has the source files for \texttt{vprerex} (visual \texttt{prerex}), a graphical ``wrapper'' for \texttt{prerex} which incorporates a prerex-enabled PDF viewer. For initial creation of a prerex-formatted chart or making substantial changes to the boxes and arrows of an existing prerex-formatted chart, it is more convenient to use one of these programs than to edit the source file directly; however, the chart editor has no access to other elements of a source file, such as preamble declarations, headings, notes, logos, and so on. A conventional text editor or \LaTeX\ development environment should be used for these. \section{Source Files} \label{source} \subsection{Overall Structure} A \texttt{.tex} file is essentially text with interspersed \LaTeX\ commands, much as a web-page description has text with Hypertext Mark-up Language (HTML) tags interspersed. Commands for \LaTeX\ can be recognized by the initial backslash character~``\verb|\|''. The first several lines make up the ``preamble'' of the source file for a chart: \begin{verbatim} \documentclass{article} \usepackage{prerex} : \end{verbatim} This describes the kind of document to be processed (\texttt{article}, as opposed to \texttt{book} or \texttt{report}) and indicates a file of definitions to be used (\texttt{prerex.sty}). The remaining lines of the preamble specify such things as the page layout and the fonts to be used. The structure \begin{verbatim} \begin{document} : \end{document} \end{verbatim} contains the content of the document. Typically, the first element of the content is a heading, contained within a formatting structure of the form \begin{verbatim} \begin{center} : \end{center} \end{verbatim} which specifies that each line of the material contained should be centered on the page. The double-backslash command \verb|\\| indicates a line break. After the heading comes the description of the chart itself: \begin{verbatim} \begin{chart} : \end{chart} \end{verbatim} Finally, there will typically be some notes to explain the abbreviations and conventions used in the chart. \subsection{Chart Instructions} Table~\ref{instructions} %on page~\pageref{instructions} summarizes the formats of the instructions defined by \texttt{prerex.sty}. \begin{table} \begin{center} \renewcommand{\arraystretch}{1.3333} \begin{tabular}{|l|} \hline \multicolumn{1}{|c|}{\textbf{Course Boxes and Text-Lines}} \\ \hline \verb|\halfcourse |$x,y$:\verb|{|\emph{course code}\verb|}{|\emph{course title}\verb|}{|\emph{timetable code}\verb|}| \\ \verb|\fullcourse |$x,y$:\verb|{|\emph{course code}\verb|}{|\emph{course title}\verb|}{|\emph{timetable code}\verb|}| \\ \verb|\reqhalfcourse |$x,y$:\verb|{|\emph{course code}\verb|}{|\emph{course title}\verb|}{|\emph{timetable code}\verb|}| \\ \verb|\opthalfcourse |$x,y$:\verb|{|\emph{course code}\verb|}{|\emph{course title}\verb|}{|\emph{timetable code}\verb|}| \\ \verb|\reqfullcourse |$x,y$:\verb|{|\emph{course code}\verb|}{|\emph{course title}\verb|}{|\emph{timetable code}\verb|}| \\ \verb|\optfullcourse |$x,y$:\verb|{|\emph{course code}\verb|}{|\emph{course title}\verb|}{|\emph{timetable code}\verb|}| \\ \verb|\halfcoursec | $x,y$ \verb|:{| \emph{course code} \verb|}{| \emph{course title} \verb|}{| \emph{timetable code} \verb|}| \verb|{| \emph{color} \verb|}| \\ \verb|\reqhalfcoursec | $x,y$ \verb|:{| \emph{course code} \verb|}{| \emph{course title} \verb|}{| \emph{timetable code} \verb|}| \verb|{| \emph{color} \verb|}| \\ \verb|\opthalfcoursec | $x,y$ \verb|:{| \emph{course code} \verb|}{| \emph{course title} \verb|}{| \emph{timetable code} \verb|}| \verb|{| \emph{color} \verb|}| \\ \verb|\fullcoursec | $x,y$ \verb|:{| \emph{course code} \verb|}{| \emph{course title} \verb|}{| \emph{timetable code} \verb|}| \verb|{| \emph{color} \verb|}| \\ \verb|\reqfullcoursec | $x,y$ \verb|:{| \emph{course code} \verb|}{| \emph{course title} \verb|}{| \emph{timetable code} \verb|}| \verb|{| \emph{color} \verb|}| \\ \verb|\optfullcoursec | $x,y$ \verb|:{| \emph{course code} \verb|}{| \emph{course title} \verb|}{| \emph{timetable code} \verb|}| \verb|{| \emph{color} \verb|}| \\ \verb|\mini |$x,y:$\verb|{|\emph{course code}\verb|}| \\ \verb|\text |$x,y:$\verb|{|\emph{line of text}\verb|}| \\ \hline \multicolumn{1}{|c|}{\textbf{Arrows}} \\ \hline \verb|\prereq |$x_0, y_0, x_1, y_1$: \hfil \verb|\prereqc |$x_0, y_0, x_1, y_1$; \emph{c}: \\ \verb|\coreq |$x_0, y_0, x_1, y_1$: \hfil \verb|\coreqc |$x_0, y_0, x_1, y_1$; \emph{c}: \\ \verb|\recomm |$x_0, y_0, x_1, y_1$: \hfil \verb|\recommc |$x_0, y_0, x_1, y_1$; \emph{c}: \\ \hline \multicolumn{1}{|c|}{\textbf{Coordinate Grid}} \\ \hline \verb|\grid| \\ \hline \multicolumn{1}{|c|}{\textbf{In-Line Instructions}} \\ \hline \verb|\solidarrow| \\ \verb|\dottedarrow| \\ \verb|\dashedarrow| \\ \verb|\lightbox| \\ \verb|\boldbox| \\ \verb|\dottedbox| \\ \hline \end{tabular} \renewcommand{\arraystretch}{1.0} \end{center} \caption{Instructions for \texttt{prerex}-Formatted Prerequisite Charts} \label{instructions} \end{table} The \verb\grid\ command creates a light gray ``coordinate grid'' in the background of the chart. Figure~\ref{grid} on page~\pageref{grid} shows the example chart of Figure~\ref{chart} with the coordinate grid enabled. \input{introchart2} Note that the ``origin'' of the coordinate system (the point with $x$-coordinate $0$ and $y$-coordinate $0$) is at the lower-left corner of the chart. The arrows produced by \verb\prereq\, \verb\coreq\, and \verb\recomm\ instructions by default are slightly curved (except very short ones). It is possible to increase or decrease the degree of curvature of a particular arrow by using instructions \verb\prereqc\, \verb\coreqc\, or \verb\recommc\; the additional argument specifies the degree of curvature: $0$ means no curvature, i.e.,~straight, and to increase the curvature, use a larger number (up to $100$). To change the default curvature for \emph{all} arrows, see Section~\ref{config} on page~\pageref{config} below. The ``in-line'' instructions create small examples of course boxes and arrows for use in explanatory notes outside of the \verb\chart\ environment: \begin{list}{}{}\item \renewcommand{\arraystretch}{1.25} \begin{tabular}{lc} \verb|\solidarrow| & \solidarrow \\ \verb|\dottedarrow| & \dottedarrow \\ \verb|\dashedarrow| & \dashedarrow \\ \verb|\lightbox| & \lightbox \\ \verb|\boldbox| & \boldbox \\ \verb|\dottedbox| & \dottedbox \end{tabular} \renewcommand{\arraystretch}{1.0} \end{list} See the manual pages \texttt{prerex(5)} and \texttt{prerex.sty(7)} and the documentation for \texttt{prerex.sty} for more information. \subsection{\LaTeX\ Input Conventions} The following are some of the input conventions for \LaTeX\ that you might want to know about while editing the source file for a prerex-formatted prerequisite chart. \begin{itemize} \item The characters \verb|# $ % & _ { } ~ ^ \ | are interpreted in special ways by \LaTeX; to produce any of the first seven of these characters, you will have to ``escape'' them with a backslash, as in, for example, \verb|\&|. The \verb|\\| combination produces a line break; to produce a backslash, use \verb|\backslash|. The remaining two special characters, \verb|~| and \verb|^|, may also be escaped with a backslash but produce accents; for example, \verb|\^{u}| produces~\^{u}. \item To produce a space where \LaTeX\ would normally not do so, use \verb|\ |. For example, \LaTeX\ normally interprets a period immediately after a word as the end of a sentence and leaves a larger-than-usual space; to prevent the larger-than-usual space after an abbreviation that finishes with a period, use \verb|\ | instead of a space, as in \verb|Diff.\ Equations|. \item An unescaped \verb\%\ character signals the beginning of a comment; any characters following the \verb\%\ to the end of that line are ignored by \LaTeX. \item To prevent a line break between two words, use a \verb\~\ instead of a space between them, as in \verb\MATH~223\. \item To leave a smaller-than-usual space between two words, use \verb|\,| instead of a space between them, as in \verb|MATH\,223|. \item To prevent hyphenation of some word, use the word as the argument to an \verb|\mbox| command, as in \verb|\mbox{Robert}|. \end{itemize} \subsection{Configuration} \label{config} The following \LaTeX\ definitions are made in \verb|prerex.sty| but may be re-defined by the user in the chart source file: \begin{list}{}{} \item \verb|\newcommand{\DefaultCurvature}{20}| \end{list} where the argument should be in the range $0$--$100$; $0$ means no curvature. \begin{list}{}{} \item \verb|\newcommand{\CourseURL}[3]{#3.html}| \end{list} where the arguments supplied at the call are the $x$ and $y$ coordinates of the box or mini, and the course code. \begin{list}{}{} \item \verb|\newcommand{\background}{yellow!15}| \end{list} which defines the default background color for course nodes. \begin{list}{}{} \item \verb|\setlength{\unit}{5.7816pt}| \end{list} which defines the absolute size of a coordinate unit; this results in exactly 10 pixels per coordinate unit if the chart is converted to an image at 125 dpi. \begin{list}{}{} \item \verb|\newcommand{\dpi}{125}| \item \verb|\newcommand{\PixelsPerUnit}{10}| \end{list} These three commands have to re-defined together if the image-map data are to be correct. \begin{list}{}{} \item \verb|\setcounter{diagheight}{75}| \end{list} which is the $y$-coordinate of the top of the diagram (reduced to $65$ in landscape mode); the nominal diagram width is \verb|\textwidth|~$\div$~\verb|\unit|~$+ 10$. The following define the thicknesses of the three kinds of arrows and the thickness of bold boxes: \begin{list}{}{} \item \verb|\newcommand{\solidwidth}{0.5pt}| \item \verb|\newcommand{\dottedwidth}{0.8pt}| \item \verb|\newcommand{\dashedwidth}{0.8pt}| \item \verb|\newcommand{\boldwidth}{1.0pt}| \end{list} The following command is used to change to a smaller size for course codes, timetable information, and mini-course codes: \begin{list}{}{} \item \verb|\newcommand{\smallersize}{\relsize{-3}}| \end{list} The following command defines the baseline adjustment for the stand-alone arrows and boxes; this parameter is font-dependent. \begin{list}{}{} \item \verb|\newcommand{\baselineAdj}{-0.5ex}| \end{list} \newpage \section*{Bibliography} \addcontentsline{toc}{section}{Bibliography} \label{bibliography} The following \nocite{Kopka,Lamport,Mittelbach} are three recommended books on \LaTeX\@.

Tennent\\\texttt{rdt@cs.queensu.ca}} \date{\today} \maketitle \thispagestyle{empty} \section{Description} \texttt{prerex.sty} defines macros that [pdf]\LaTeX\ can use to draw charts consisting of labelled course boxes linked by arrows that represent pre- and co-requisite requirements; see the example chart in Figure~\ref{chart} on page~\pageref{chart}. In addition to the usual [pdf]\LaTeX\ output, auxiliary files will be generated containing image-map data for the hyperlinked nodes in the diagram and a shell script for cropping a PNG image obtained from the [pdf]\LaTeX\ output. If the source file satisfies the constraints of the \textsf{prerex(5)} format, a chart description may be edited using the \textsf{prerex(1)} interactive editor (as well as any conventional text editor). \begin{figure} \setcounter{diagheight}{40} \begin{chart} \text 15,40:{\textsf{\textbf{\Large Computer Science}}} \reqfullcourse 50,35:{1083}{Comput.\,Sci.\\Concepts}{TTh 10:00} \reqhalfcourse 25,30:{1303}{Discrete\\Structures}{MWF 9:30} \reqhalfcourse 30,20:{2813}{Computer\\Organiz.\,I}{MWF 8:30} \prereq 50,35,30,20: \prereq 25,30,30,20: \reqhalfcourse 45,20:{2023}{Procedural\\Prog.\,Devel.}{MWF 2:30} \prereq 50,35,45,20: \reqhalfcourse 65,20:{2513}{Informat.\\Systems}{TTh 1:00} \coreq 50,35,65,20: \mini 10,16:{1083} \reqhalfcourse 10,10:{2333}{Computab.\,\&\\Formal\,Lang.}{TTh 11:30} \prereq 25,30,10,10: \prereq 10,16,10,10: \reqhalfcourse 45,10:{2013}{Software\\Engineer.\,I}{MWF 11:30} \prereq 45,20,45,10: \halfcourse 55,10:{2685}{\texttt{C++}\\Program.}{no} \prereq 45,20,55,10: \mini 21,6:{2013} \reqhalfcourse 15,0:{3323}{Data\\Structures}{MWF 10:30} \prereq 25,30,15,0: \prereq 21,6,15,0: \reqhalfcourse 25,0:{3813}{Comput.\\Organiz.\,II}{TTh 8:30} \prereq 30,20,25,0: \reqhalfcourse 35,0:{3413}{Operating\\Systems\,I}{MWF 9:30} \prereq 30,20,35,0: \recomm 45,10,35,0: \halfcourse 45,0:{3013}{Software\\Engineer.\,II}{MWF 11:30} \prereq 45,10,45,0: \halfcourse 58,0:{3513}{Database\\Mngt.\,Sys.\,I}{MWF 8:30 pm} \prereq 65,20,58,0: \prereq 45,10,58,0: \reqhalfcourse 70,0:{3503}{Sys.\,Anal.\\\&\,Design}{TTh 10:00} \prereq 65,20,70,0: \end{chart} \paragraph{Notes} \begin{itemize} \item A solid arrow \solidarrow\ indicates a required prerequisite, a dotted arrow \dottedarrow\ indicates a corequisite (to be taken before or concurrently), and a dashed arrow \dashedarrow\ indicates a recommended prerequisite. Core courses are in \boldbox\ boxes; other courses (i.e.,~options or prerequisites) are in \lightbox\ boxes. \item Timetable abbreviations: M, T, W, Th, F$=$Mon, Tue, Wed, Thur, Fri, resp.; no$=$not offered. \item \dots \end{itemize} \caption{A Prerequisite Chart} \label{chart} \end{figure} \section{Terminology} A prerequisite chart consists of a number of \emph{course boxes}, linked by \emph{arrows}. Courses are either \emph{half} or \emph{full}, and may be \emph{required} or \emph{optional} (or neither). Each course box can contain a course \emph{code} (upper left corner), a course \emph{title} (lower half), and \emph{timetable} information (upper right corner). An arrow can be either a \emph{prerequisite} (solid), a \emph{corequisite} (dotted), or \emph{recommended} (dashed). When a conventional arrow would be inappropriate, it is possible to use a \emph{mini} course ``box'' (consisting of just a course code) just above a target box. A line of text may be placed anywhere on the chart. \section{Coordinate System} A conventional two-dimensional Cartesian coordinate system is used to specify the locations of diagram elements. The origin (where $x = 0$ and $y = 0$) is at the lower-left corner of the diagram. The diagram height is configurable; the width is determined by the values of \verb|\textwidth| and an adjustable \verb|\unit| length, which defines the absolute value of a coordinate unit. It is possible to put a coordinate grid with labelled axes in the background of a chart. The coordinates of a \emph{box,} \emph{mini,} or \emph{text-line} are those of its centre point. An \emph{arrow} is described by the coordinates of the centre points of its source and target boxes/minis/text-lines. \section{Usage} The command \verb|\usepackage{prerex}| should appear in the document preamble. This will define a \LaTeX\ environment \begin{list}{}{} \item \verb|\begin{chart}|\quad$\cdots$\quad \verb|\end{chart}| \end{list} within which the commands described in the following sub-sections may be used to produce course boxes, minis, text-lines, and arrows. The order of commands is not significant except that the commands for the source and target boxes of an arrow should precede the command for the arrow, and the \verb|\grid| command, if present, should precede other chart commands. \subsection{Course Boxes} The commands producing course boxes have the following forms: \begin{list}{}{} \item \verb|\halfcourse | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \item \verb|\reqhalfcourse | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \item \verb|\opthalfcourse | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \item \verb|\fullcourse | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \item \verb|\reqfullcourse | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \item \verb|\optfullcourse | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \end{list} where $x,y$ are the coordinates of the centerpoint of the box, relative to the origin of the coordinate system at the lower-left corner of the diagram. The \emph{code}, \emph{title}, and \emph{timetable} arguments are arbitrary (well-bracketed) text, possibly with \LaTeX\ markup. The following are similar but take an additional argument to specify the (non-default) background color of the course box: \begin{list}{}{} \item \verb|\halfcoursec | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \verb|{| \emph{color} \verb|}| \item \verb|\reqhalfcoursec | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \verb|{| \emph{color} \verb|}| \item \verb|\opthalfcoursec | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \verb|{| \emph{color} \verb|}| \item \verb|\fullcoursec | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \verb|{| \emph{color} \verb|}| \item \verb|\reqfullcoursec | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \verb|{| \emph{color} \verb|}| \item \verb|\optfullcoursec | $x,y$ \verb|:{| \emph{code} \verb|}{| \emph{title} \verb|}{| \emph{timetable} \verb|}| \verb|{| \emph{color} \verb|}| \end{list} \subsection{Mini Course Boxes and Text-Lines} A mini course ``box'' is produced by a command of the form \begin{list}{}{} \item \verb|\mini| $x,y$ \verb|:{| \emph{code} \verb|}| \end{list} A text-line is produced by a command of the form \begin{list}{}{} \item \verb|\text| $x,y$ \verb|:{| \emph{line of text} \verb|}| \end{list} There are several differences between minis and text-lines. The maximum length allowed for a course-code may be less than that for a text-line. A sans-serif font and a reduced font size is used for a course-code. A course-code may be hyperlinked but a text-line is not (except when the coordinate grid is on). A \verb|\parbox| command may be used if more than one line is desired. \subsection{Arrows} Arrows between course boxes (or minis or text-lines) are produced by commands of the form \begin{list}{}{} \item \verb|\prereq| $ x_0,y_0,x_1,y_1$\verb|:| \item \verb|\coreq| $ x_0,y_0,x_1,y_1$\verb|:| \item \verb|\recomm| $ x_0,y_0,x_1,y_1$\verb|:| \end{list} These produce, respectively, solid, dotted, and dashed arrows from the course box (or mini or text-line) centered at coordinates $x_0,y_0$ to the entity centered at coordinates $x_1,y_1$. Arrows by default have a non-zero curvature (unless they are very short). It is possible to override the default curvature for a particular arrow by using the instructions \begin{list}{}{} \item \verb|\prereqc| $ x_0,y_0,x_1,y_1;c$\verb|:| \item \verb|\coreqc| $ x_0,y_0,x_1,y_1;c$\verb|:| \item \verb|\recommc| $ x_0,y_0,x_1,y_1;c$\verb|:| \end{list} where $c$ is an integer in the range $0$--$100$ specifying the desired curvature; for example, $c= 0$ will produce a straight arrow. To change the default curvature for all arrows, the user program may redefine the \verb|\DefaultCurvature| command. \subsection{Web Links} \label{WebLinks} Course boxes and minis may be hyperlinked. The default URL for course boxes is \emph{course-code}\verb|.html| where \emph{course-code} is the \emph{code} argument of the course box. The URL scheme may be changed by the user by re-defining the \verb|\CourseURL| command; see Section~\ref{Configuration}. \subsection{Coordinate Grid} The following command produces a coordinate grid with labelled axes, which is useful while editing a diagram: \begin{list}{}{} \item \verb|\grid| \end{list} This is normally placed before all the other chart commands so that grid lines are in the background, covered by course boxes, minis, text-lines, and arrows, as in Figure~\ref{grid} on page~\pageref{grid}. The \verb|\grid| command also redefines the \verb|CourseURL| command so that, in suitable PDF viewers, if the mouse cursor is placed over a box, mini, or midpoint of an arrow, the \emph{coordinates} of the box/mini/textline (or the coordinates of the source \emph{and} target of the arrow) will be displayed as follows: in the status bar in \texttt{xpdf} and \texttt{gpdf}, and in a ``tooltip'' in recent versions of \texttt{kpdf}/\texttt{okular}, \texttt{evince}, and the Acrobat Reader. This coordinate display make it easier to edit chart descriptions. When the grid is on, the mid-point of every arrow is highlighted by a ``bullet''. The \texttt{prerex} package at \url{http://www.ctan.org/tex-archive/graphics/prerex/} has a patch for \texttt{kpdf} (recently incorporated into \texttt{okular}) to allow capture coordinates of course boxes, arrows, and background points in the X selection clipboard (for pasting into a command being composed at the \texttt{prerex} prompt). There is also a GUI frontend \texttt{vprerex} to the \texttt{prerex} editor which incorporates a minimalistic prerex-enabled PDF viewer. \begin{figure} \setcounter{diagheight}{40} \begin{chart} \grid \text 15,40:{\textsf{\textbf{\Large Computer Science}}} \reqfullcourse 50,35:{1083}{Comput.\,Sci.\\Concepts}{TTh 10:00} \reqhalfcourse 25,30:{1303}{Discrete\\Structures}{MWF 9:30} \reqhalfcourse 30,20:{2813}{Computer\\Organiz.\,I}{MWF 8:30} \prereq 25,30,30,20: \prereq 50,35,30,20: \reqhalfcourse 45,20:{2023}{Procedural\\Prog.\,Devel.}{MWF 2:30} \prereq 50,35,45,20: \reqhalfcourse 65,20:{2513}{Informat.\\Systems}{TTh 1:00} \coreq 50,35,65,20: \mini 10,16:{1083} \reqhalfcourse 10,10:{2333}{Computab.\,\&\\Formal\,Lang.}{TTh 11:30} \prereq 10,16,10,10: \prereq 25,30,10,10: \reqhalfcourse 45,10:{2013}{Software\\Engineer.\,I}{MWF 11:30} \prereq 45,20,45,10: \halfcourse 55,10:{2685}{\texttt{C++}\\Program.}{no} \prereq 45,20,55,10: \mini 21,6:{2013} \reqhalfcourse 15,0:{3323}{Data\\Structures}{MWF 10:30} \prereq 21,6,15,0: \prereq 25,30,15,0: \reqhalfcourse 25,0:{3813}{Comput.\\Organiz.\,II}{TTh 8:30} \prereq 30,20,25,0: \reqhalfcourse 35,0:{3413}{Operating\\Systems\,I}{MWF 9:30} \recomm 45,10,35,0: \prereq 30,20,35,0: \halfcourse 45,0:{3013}{Software\\Engineer.\,II}{MWF 11:30} \prereq 45,10,45,0: \halfcourse 58,0:{3513}{Database\\Mngt.\,Sys.\,I}{MWF 8:30 pm} \prereq 45,10,58,0: \prereq 65,20,58,0: \reqhalfcourse 70,0:{3503}{Sys.\,Anal.\\\&\,Design}{TTh 10:00} \prereq 65,20,70,0: \end{chart} \vspace*{2ex} \caption{A Prerequisite Chart with a Coordinate Grid} \label{grid} \end{figure} \subsection{Stand-Alone Commands} The following commands may be used outside a \verb|chart| environment, such as in the explanatory notes for a chart: \begin{center} \begin{tabular}{lc} \verb|\solidarrow| & \solidarrow\\ \verb|\dottedarrow| & \dottedarrow \\ \verb|\dashedarrow| & \dashedarrow \\ \verb|\lightbox| & \lightbox \\ \verb|\boldbox| & \boldbox \\ \verb|\dottedbox| & \dottedbox \\ \end{tabular} \end{center} \section{Dependencies} This implementation of \verb|prerex.sty| uses \verb|pgf| (version~1.18 or later) with add-on package \verb|tikz|. The following additional packages are used: \verb|multido|, \verb|relsize|, \verb|calc|, \verb|ifthen|, \verb|textcomp|, \verb|zref-savepos|, and \verb|hyperref|. \emph{Either} \verb\pdflatex\ \emph{or} \verb\latex\ (followed by \verb\dvips\ and, possibly, \verb\ps2pdf\) may be used. \section{Conversion to Portable Network Graphic (PNG) Format} To convert a chart (in Postscript or PDF format) to a reasonably high-quality image, it is suggested to use the \verb|convert| tool of the \verb|ImageMagick| package as follows: \begin{verbatim} convert -density 125 chart.ps chart.png \end{verbatim} or \begin{verbatim} convert -density 125 chart.pdf chart.png \end{verbatim} The density parameter specifies the number of pixels per inch; if this is too small, the image is of poor quality, and if it is too large, the image file is too big. By default, the shell script generated by \texttt{prerex.sty} crops the image at the southeast corner. It is possible to use a PNG compression application such as \texttt{optipng} to reduce the file-size of the cropped image (without loss of quality). An auxiliary file containing image-map data for the hyperlinked nodes in the chart is also generated; consult a reference on the HTML language for an explanation of (client-side) image maps. \section{Installation} \begin{enumerate} \item install the most recent version of \verb\pgf\ from \url{http://sourceforge.net/projects/pgf/}. \item copy \verb|prerex.sty| to \emph{your-texmf-tree}\verb|/tex/latex/misc| \item copy \verb|doc/prerex.{tex,pdf}| to \emph{your-texmf-tree}\verb|/doc/latex/misc| \item if necessary, refresh the \TeX\ database (e.g., \verb|texhash|) \item copy \verb|man/prerex.sty.7| to sub-directory \verb|man7| of a \verb|man| directory on your \verb|MANPATH| \item test by doing \begin{verbatim} $ man 7 prerex.sty $ make chart.pdf \end{verbatim} \end{enumerate} \section{Configuration} \label{Configuration} The following are defined by the style file but may be re-defined by the user: \begin{list}{}{} \item \verb|\newcommand{\DefaultCurvature}{20}| \end{list} where the argument should be in the range $0$--$100$; $0$ means no curvature. \begin{list}{}{} \item \verb|\newcommand{\CourseURL}[3]{#3.html}| \end{list} where the arguments supplied at the call are the $x$ and $y$ coordinates of the box or mini and the course code. \begin{list}{}{} \item \verb|\newcommand{\background}{yellow!15}| \end{list} which specifies the default background color of course boxes. \begin{list}{}{} \item \verb|\setlength{\unit}{5.7816pt}| \end{list} which defines the absolute size of a coordinate unit; this yields 10 pixels per coordinate unit if the chart is converted to an image at 125 dpi. \begin{list}{}{} \item \verb|\newcommand{\dpi}{125}| \item \verb|\newcommand{\PixelsPerUnit}{10}| \end{list} These have to re-defined together if the image-map data are to be correct. \begin{list}{}{} \item \verb|\setcounter{diagheight}{75}| \end{list} which is the $y$-coordinate of the top of the diagram (reduced to $65$ in landscape mode); the nominal diagram width is \verb|\textwidth|~$\div$~\verb|\unit|~$+ 10$. The following define the thicknesses of the three kinds of arrows, and the thickness of bold boxes: \begin{list}{}{} \item \verb|\newcommand{\solidwidth}{0.5pt}| \item \verb|\newcommand{\dottedwidth}{0.8pt}| \item \verb|\newcommand{\dashedwidth}{0.5pt}| \item \verb|\newcommand{\boldwidth}{1.0pt}| \end{list} The following command is used to change to a smaller size for course codes, timetable information, and mini-course codes: \begin{list}{}{} \item \verb|\newcommand{\smallersize}{\relsize{-3}}| \end{list} The following command defines the baseline adjustment for the stand-alone arrows and boxes; this parameter is font-dependent. \begin{list}{}{} \item \verb|\newcommand{\baselineAdj}{-0.5ex}| \end{list} \section{Implementation Details} \subsection{Boxes} To improve the appearance, boxes are drawn with slightly rounded corners. The half-course boxes are assigned a minimum height to give a more uniform appearance to horizontal rows of such boxes. The mini and text boxes have white frames and their fill colour is white, which is assumed to be the background colour of the chart. A text box is not normally hyperlinked; however, if the coordinate grid is on, it is hyperlinked and its chart coordinates are encoded in the URI. \subsection{Arrows} Arrows with a small height and arrows whose source and target points have equal x or y coordinates are always draw straight (using a specialized and simpler macro) unless an explicit non-zero curvature argument is provided. If the coordinate grid is on, a hyperlink with the source and target coordinates is placed at the mid-point of the arrow. A wider background white edge is drawn below an arrow to improve the appearance of crossing arrows; the background also ensures visibility of the arrow when the coordinate grid is on. A thin white arrow (with a visible arrowhead) is drawn beneath the visible arrow to obtain a thin arrowhead. \subsection{Coordinate Grid and Associated Changes} When the coordinate grid is drawn, the \texttt{CourseURL} command is re-defined to pass node coordinates in URIs. Also, two ``anchor'' hyperlinks are inserted at the southwest and northeast corners of the diagram to allow prerex-enabled PDF viewers to compute chart coordinates. \subsection{Chart Images} \enlargethispage*{8ex} To support HTML versions of charts, \texttt{prerex.sty} generates a script to crop a chart image at the southeast corner, allowing descriptive notes below the chart to be treated as ordinary text. Also, it generates image-map data for use with an HTML image map.

Installation of prerex.sty: + copy prerex.sty to your-texmf-tree/tex/latex/misc + copy doc/prerex.{tex,pdf} to your-texmf-tree/doc/latex/misc + if necessary, refresh the TeX database (e.g., texhash) + copy doc/prerex.sty.7 to sub-directory man7 of a man directory on your MANPATH + test by doing man 7 prerex.sty pdflatex chart.tex See doc/prerex.pdf for detailed documentation. The prerex editor allows interactive editing of the chart environments of LaTeX source files. It supports add, remove, cut-and-paste, and edit operations on course boxes and arrows, and vertical or horizontal shifts of the whole diagram or selected sets of course boxes. When a course box is moved, the arrows into and out of it automatically follow. To install: tar zxvf prerex-6.4.0.tar.gz cd prerex-6.4.0 ./configure --help ./configure [options] make sudo make install The effects of editing operations may be observed in any PDF viewer. The vprerex (visual prerex) application included in the prerex suite is a GUI and viewer for the prerex editor. It may be used just as a minimalistic viewer of arbitrary PDF files but supports editing of charts generated using prerex.sty by allowing coordinates of course boxes, arrows, and background points to be conveyed back to the prerex editor command-line using the clipboard. See the INSTALL in the tarball for installation instructions. See the file doc/intro.pdf for an overview of the prerex system. prerex.sty, README.prerex, prerex.1, prerex.5, prerex.sty.7, prerex.tex and chart.tex may be modified and distributed according to the terms of the LaTeX Project Public License.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. prerex-6.4.0/prerex-6.4.0/Makefile.in0000644000123700002140000011302511742020767015211 0ustar rdtrdt# Makefile.in generated by automake 1.11.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, # Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : bin_PROGRAMS = prerex$(EXEEXT) subdir = .

The user does not normally have to be familiar with details of the format. The editor supports add, remove, cut-and-paste, and edit operations on diagram elements, and shifts of a list of specified elements or the entire diagram. The edited diagram may be saved, re-processed, and viewed in a PDF viewer, without exiting the editor. Alternatively, .BR vprerex (1) will embed a .BR prerex (1) window and display the corresponding PDF file alongside. .SH TERMINOLOGY A prerequisite chart consists of several .I course boxes, linked by .I arrows. Courses are either .I half or .I full, and may be .I required or .I optional (or neither). Each course box contains a course .I code (upper left corner), a course .I title (lower half), and .I timetable information (upper right corner). An arrow is either a .I prerequisite (solid), a .I corequisite (dotted), or .I recommended (dashed). When a conventional arrow would be inappropriate, a .I mini course just above a target box may be used. A line of text may have been placed anywhere in the chart. .PP In some implementations of the .BR prerex (5) format, (some) arrows may be curved and by default have non-zero curvature. The curvature of individual arrows may be edited using the .BR prerex (1) editor. To modify the default curvature (or set it to zero), see .BR prerex.sty (7). .SH COORDINATE SYSTEM A conventional two-dimensional coordinate system is used to specify the locations of diagram elements; the origin (where .I x = 0 and .IR "y = 0" ) is at the lower-left corner of the diagram. For convenience, a coordinate grid is normally displayed in the background while a diagram is being edited. .PP The coordinates of a .I box, .I mini, or .I text-line are those of its centre point. An .I arrow is described by the coordinates of the centre points of its source and target boxes/minis/text-lines. The notation .IB "x0,y0" : "x1,y1" denotes all the nodes (course boxes, minis, texts) in the rectangle whose northwest and southeast corners are at coordinates .IR "x0,y0 " and " x1,y1." .SH USAGE If .B prerex is invoked on one existing file, a back-up copy is made of it, the .I x,y coordinate grid is turned on, the file is processed by using a system call to .BR pdflatex (1), and then the user gets a command summary and an interactive prompt of the form .IP .I file.tex> .LP If no file argument is given on the command line, the user is prompted to supply a file name. In either case, if the file name provided does not have a .I .tex extension, .I .tex is appended to it. .PP If the .I file.tex file named does .I not already exist, a new "empty" chart file with that name is created, and then it is processed as above. .PP If a .I second filename is provided, the first filename is treated as the base file of a LaTeX document and the second as an included file that contains the .I chart environment to be edited. This allows more than one document to share an included chart file and allows more than one chart to be included in a single document. .PP The user may enter commands at the interactive command prompt as follows: .TP 18 .BI box " x,y" edit a course box at .I x,y, if necessary, creating a new course box there .TP .BI mini " x,y" edit a mini at .I x,y, if necessary, creating a new mini there .TP .BI text " x,y" edit a text-line at .I x,y, if necessary, creating a new text-line there .TP .BI arrow " x0,y0,x1,y1" edit an arrow from .I x0,y0 to .I x1,y1, if necessary, creating a new such arrow .TP .BI cut " xi,yi ... " (temporarily) remove the box, mini, or text at .I xi,yi (including arrows into/out of the box/mini/text) .TP .BI "paste [" x,y "]" re-insert most recently cut but not yet pasted box, mini, or text at .I x,y (including arrows into/out of the box/mini/text), or at the original coordinates if .I " x,y" omitted .TP .BI xchange " x0,y0 x1,y1" exchange the box, mini or text at .I x0,y0 with that at .I x1,y1. This is implemented as a sequence of two cuts followed by two pastes to the same points. .TP .BI "delete [ " x,y " | " x0,y0,x1,y1 " | " x0,y0 : x1,y1 " ] " ... remove the specified boxes, minis, texts, or arrows (including automatically all arrows into/out of each box/mini/text) .TP .B undo undo the most recent editing command (not already undone) .TP .BI "shift [\-]" s " [ " x,y " | " x0,y0 : x1,y1 " ] " ... move specified diagram elements .I x units right [left]; if no elements are specified, the whole diagram is shifted .TP .BI "raise [\-]" r " [ " x,y " | " x0,y0 : x1,y1 " ] " ... move specified diagram elements .I y units up [down]; if no elements are specified, the whole diagram is raised .TP .B "write, !" save to the current .I chartfile.tex and process the chart by calling .BR pdflatex (1) on the base file. .TP .B "quit, exit, x, ^D" turn off the coordinate grid, restore write-access, save to the current .I chartfile.tex, process the base file and exit. .TP .BI ! cmd restore write access to .I chartfile.tex, execute shell command .I cmd, re-load and re-process the base file (in case the command changed anything), and remove write-access. .TP .B "Backup" copy the current .I chartfile.tex to the back-up file .IR .chartfile.tex; equivalent to .BI !cp " chartfile.tex .chartfile.tex" .TP .B "Restore" delete the current .I chartfile.tex and editing buffer, and replace them using the current back-up in .I .chartfile.tex. .TP .BR grid " [y/n]" turn on/off coordinate-grid background .TP .BR "help, ?" print a command summary .LP After most editing commands, the editing buffer is automatically saved to .I chartfile.tex and the basefile is processed; the .B cut and .B paste commands are exceptions: saving and processing take place only when all outstanding cuts have been pasted. Saving and processing can be .I forced by using the .B write (or .BR ! ) command, or .I suppressed for all commands (except .BR write and .BR ! ) by appending a ";" to the command immediately prior to entering it. To exit the editor .I without saving to the current .IR chartfile.tex , use .B quit; (.i.e., .B quit followed by a semi-colon) or a similar combination. Starting in Version 3.8, .B ^C and other interrupts result in the editing buffer being saved to .I chartfile.tex before the editor is exited. .SH OPTIONS .TP 8 .BR -v output program name and version number, and quit .TP .BR -h output usage summary and quit .SH NOTES The main difference between .B mini and .B text is in the maximum lengths for the text displayed; the latter allows a full line of text, not merely a course code. Also a text-line does not have an associated URI (when the grid is off). The text "line" may actually be displayed as a paragraph by using a LaTeX \\parbox. .PP To save the current state of .I chartfile.tex, use .B Backup or a comparable shell command. A history list of interpreted commands is maintained and is accessible using the up-arrow key. .PP If processing of the chart fails, .B prerex will attempt to display the LaTeX error message from the log file. The chart file can be fixed using a conventional text editor or LaTeX-oriented editor. LaTeX processing should fail only if there is an initial problem or if ill-formed LaTeX markup has been inserted into a text field. .PP Any (non-empty) prefix of a command suffices; for example, .BR q , .BR qu , or .B qui may be used instead of .BR quit . Some of the commands will begin a dialogue with the user in order to fill in or modify properties; the prompts should be self-explanatory. .PP While the TeX chart file is being edited by .B prerex, its protection is set to read-only (except when it is being regenerated or restored, or during a shell-command execution), to try to prevent inadvertent interference from concurrent editing; this is not fail-safe. .PP Since version 5.5, .B prerex no longer automatically calls a PDF viewer (because it may be embedded in an instance of .BR vprerex (1) which already provides a PDF display). If .B prerex is being used by itself, a PDF viewer may be invoked using the .BI ! cmd shell-escape mechanism. Also, .B prerex no longer interacts with the user until a PDF file is available; this is for use with .BR vprerex (1). For example, if the .tex file is initially read-only, .B prerex aborts. .SH FILES A LaTeX style file .BR prerex.sty (7) that implements the macro calls defined by the .BR prerex (5) format must be available to .BR [pdf]latex (1) to process the chart file. Before any editing is allowed, .I chartfile.tex is copied to .I .chartfile.tex as a backup. .SH ENVIRONMENT .PP The most convenient viewing program to use with .B prerex is one like .BR gv (1), .BR gsview (1), .BR kghostview(1), .BR kpdf (1) or .BR okular (1) that may be configured to "watch" the pdf file and re-load the display automatically when the file changes. .BR evince (1) has a Reload button and .BR xpdf (1) supports re-loading using the keystroke "R", but re-loading is much less convenient with .BR acroread (1) and .BR gpdf (1), which may have to be re-started. .PP Recent versions of some PDF viewers show the URIs of hyperlinks in a tooltip or in the status bar; this mechanism is used by some implementations of .BR prerex.sty (7) to allow display of the coordinates of a box, mini, text-line, or arrow when the mouse hovers over it (while the coordinate grid is on and the relevant chart file is presumably being edited). .PP The .B prerex package at .B http://www.ctan.org/tex-archive/graphics/prerex/ has a patch for .BR kpdf (1) (now incorporated into .BR okular (1)) to make it display URIs in tooltips and also to allow the user to capture coordinates of course boxes, arrows, and background points in the X selection clipboard (for pasting into a command being composed at the .B prerex prompt). .PP At the same site, there is also source code for .BR vprerex (1), a GUI front-end for .B prerex which is similarly prerex-enabled. .SH BUGS .B prerex analyzes chart files without using TeX; thus, macro calls are .I not expanded, and anything in the chart file before or after the (first) .B "\ebegin{chart} ... \eend{chart}" environment is ignored (but preserved) by the editor. Lines that begin with "%" within the chart environment are preserved but other comments within the chart environment are .I not preserved and may interfere with command parsing. .PP From version 5.6, .B prerex no longer supports the latex -> dvips -> ps2pdf toolchain as an option. .SH AUTHOR R.

It supports add, remove, cut-and-paste, and edit operations on course boxes and arrows, and vertical or horizontal shifts of the whole diagram or selected sets of course boxes. When a course box is moved, the arrows into and out of it automatically follow. The effects of editing operations may be observed in any PDF viewer. The "vprerex" (visual prerex) application (not included here) is a GUI and viewer for the prerex editor. It may be used just as a minimalistic viewer of arbitrary PDF files but supports editing of charts generated using prerex.sty by allowing coordinates of course boxes, arrows, and background points to be conveyed back to the prerex editor command-line using the clipboard. prerex-6.4.0/prerex-6.4.0/libedit/0000755000123700002140000000000011742036351014552 5ustar rdtrdtprerex-6.4.0/prerex-6.4.0/libedit/src/0000755000123700002140000000000011742036351015341 5ustar rdtrdtprerex-6.4.0/prerex-6.4.0/libedit/src/unvis.c0000644000123700002140000003501411727141274016660 0ustar rdtrdt/* $NetBSD: unvis.c,v 1.38 2011/11/18 20:28:17 christos Exp $ */ /*- * Copyright (c) 1989, 1993 * The Regents of the University of California.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the `--target=TYPE' option to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc will cause the specified gcc to be used as the C compiler (unless it is overridden in the site shell script). `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. prerex-6.4.0/prerex-6.4.0/libedit/aclocal.m40000644000123700002140000010560011741702721016414 0ustar rdtrdt# generated automatically by aclocal 1.11.1 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, [m4_warning([this file was generated for autoconf 2.63.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Now with UTF-8 support. To enable this run 'configure --enable-widec'. For now an UTF-32 encoded wchar_t is required. This requirement is met on NetBSD, Solaris and OS X for any UTF-8 locale, and any system that define __STDC_ISO_10646__ (e.g. GNU libc on Linux). 2009-09-23 Jess Thrysoee * version-info: 0:34:0 * all: apply Apple patches from: http://opensource.apple.com/source/libedit/libedit-11/patches 2009-09-05 Jess Thrysoee * version-info: 0:33:0 * all: Use predefined macro __sun to identify Solaris * src/el.c: Ignore comment lines in .editrc 2009-07-23 Jess Thrysoee * version-info: 0:32:0 * all: sync with upstream source. 2009-06-10 Jess Thrysoee * version-info: 0:31:0 * all: sync with upstream source. 2009-05-03 Jess Thrysoee * version-info: 0:30:0 * all: sync with upstream source. 2009-04-05 Jess Thrysoee * version-info: 0:29:0 * all: sync with upstream source. 2009-01-11 Jess Thrysoee * version-info: 0:28:0 * all: sync with upstream source. MAJOR.MINOR version is now 3.0. This is due to NetBSD changing time_t and dev_t to 64 bits. It does not really effect this package. * configure.ac: Remove '--enable-debug' configure flag. The autoconf way to control flags is by specifying them when running configure, e.g. 'CFLAGS="-O0 -g" ./configure' 2008-07-12 Jess Thrysoee * version-info: 0:27:0 * configure.ac: Added '--enable-debug' configure flag, to produce debugging information. * examples/fileman.c: cast stat struct members, st_nlink and st_size, appropriately (see also 'man 2 stat'). Patch by Alex Elder. * all: sync with upstream source. MINOR version is now 11. 2007-08-31 Jess Thrysoee * version-info: 0:26:0 * libedit.pc.in,Makefile.am,configure.ac,patches/extra_dist_list.sh: Added pkg-config support for libedit.

This is just a manpage update 2005-08-28 Jess Thrysoee * version-info: 0:14:0 * src/sys.h: include config.h to avoid "redefinition of `u_int32_t'". Patch by Norihiko Murase. * src/search.c: explicitly include sys/types.h, because regex.h on FreeBSD needs it and does not include it itself. Patch by Norihiko Murase. * acinclude.m4: added EL_GETPW_R_DRAFT test and use AC_TRY_LINK instead of AC_TRY_COMPILE.

Reported by Gerrit P. Haase. * src/Makefile.am: Added libtool -no-undefined. This is needed on Cygwin to get a shared editline library. Should not affect other platforms. Suggested by Gerrit P. Haase. 2005-06-15 Jess Thrysoee * version-info: 0:8:0 * all: sync with upstream source. 2005-06-01 Jess Thrysoee * version-info: 0:7:0 * all: sync with upstream source. * src/readline.c, src/filecomplete.c: Solaris use POSIX draft versions of getpwent_r, getpwnam_r and getpwuid_r which return 'struct passwd *'. Define HAVE_GETPW_R_POSIX if these functions are (non draft) POSIX compatible.

We must quote the arguments since Win32 CreateProcess() interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a special way: - Space and tab are interpreted as delimiters. They are not treated as delimiters if they are surrounded by double quotes: "...". - Unescaped double quotes are removed from the input. Their only effect is that within double quotes, space and tab are treated like normal characters. - Backslashes not followed by double quotes are not special. - But 2*n+1 backslashes followed by a double quote become n backslashes followed by a double quote (n >= 0): \" -> " \\\" -> \" \\\\\" -> \\" */ #define SHELL_SPECIAL_CHARS "\"\\ \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" #define SHELL_SPACE_CHARS " \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" char ** prepare_spawn (char **argv) { size_t argc; char **new_argv; size_t i; /* Count number of arguments. */ for (argc = 0; argv[argc] != NULL; argc++) ; /* Allocate new argument vector. */ new_argv = XMALLOC (char *, argc + 1); /* Put quoted arguments into the new argument vector. */ for (i = 0; i < argc; i++) { const char *string = argv[i]; if (string[0] == '\0') new_argv[i] = xstrdup ("\"\""); else if (strpbrk (string, SHELL_SPECIAL_CHARS) != NULL) { int quote_around = (strpbrk (string, SHELL_SPACE_CHARS) != NULL); size_t length; unsigned int backslashes; const char *s; char *quoted_string; char *p; length = 0; backslashes = 0; if (quote_around) length++; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') length += backslashes + 1; length++; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) length += backslashes + 1; quoted_string = XMALLOC (char, length + 1); p = quoted_string; backslashes = 0; if (quote_around) *p++ = '"'; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') { unsigned int j; for (j = backslashes + 1; j > 0; j--) *p++ = '\\'; } *p++ = c; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) { unsigned int j; for (j = backslashes; j > 0; j--) *p++ = '\\'; *p++ = '"'; } *p = '\0'; new_argv[i] = quoted_string; } else new_argv[i] = (char *) string; } new_argv[argc] = NULL; return new_argv; } EOF ;; esac cat <<"EOF" void lt_dump_script (FILE* f) { EOF func_emit_wrapper yes | $SED -n -e ' s/^\(.\{79\}\)\(..*\)/\1\ \2/ h s/\([\\"]\)/\\\1/g s/$/\\n/ s/\([^\n]*\).*/ fputs ("\1", f);/p g D' cat <<"EOF" } EOF } # end: func_emit_cwrapperexe_src # func_win32_import_lib_p ARG # True if ARG is an import lib, as indicated by $file_magic_cmd func_win32_import_lib_p () { $opt_debug case `eval $file_magic_cmd \"\$1\" 2>/dev/null | $SED -e 10q` in *import*) : ;; *) false ;; esac } # func_mode_link arg... func_mode_link () { $opt_debug case $host in *-*-cygwin* | *-*-mingw* | *-*-pw32* | *-*-os2* | *-cegcc*) # It is impossible to link a dll without this setting, and # we shouldn't force the makefile maintainer to figure out # which system we are compiling for in order to pass an extra # flag for every libtool invocation. # allow_undefined=no # FIXME: Unfortunately, there are problems with the above when trying # to make a dll which has undefined symbols, in which case not # even a static library is built.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Here is a another example: /bin/bash ./configure CONFIG_SHELL=/bin/bash Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent configuration-related scripts to be executed by `/bin/bash'. `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. prerex-6.4.0/prerex-6.4.0/aclocal.m40000644000123700002140000010772011741661043015006 0ustar rdtrdt# generated automatically by aclocal 1.11.1 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, [m4_warning([this file was generated for autoconf 2.63.

Version 6.3.2, 2012-03-28 Support coordinate ranges for delete, shift, raise commands. Multiple-step commands undone atomically. Version 6.3.1, 2012-03-26 Support xchange command. Display new coordinates of shifted/raised nodes for subsequent raise/shift. Version 6.3, 2012-03-21 Support opt course boxes. Version 6.2.1, 2012-03-18 Allow multiple coordinate pairs in cut command. Version 6.2, 2011-09-08 Replace undelete command by a general multi-level undo command. Default for undoing paste command is to re-insert at the original coordinates. Version 6.1.1, 2011-08-20 Fixed missing else which resulted in re-reading ...coursec commands. Better prompt for background color of a course box. Better error message if more than one node at a point. Version 6.1.0, 2011-08-18 Deal with commands \halfcoursec etc. that allow background-color specification. Version 6.0.4, 2011-07-27 Deleted prerex_LDFLAGS from src/Makefile.am. Version 6.0.3, 2010-07-04 Use only one of ncurses/termcap. Version 6.0.2, 2010-06-29 Deleted reference to stdbool.h. Modified configuration scripts to allow for readline using ncurses/termcap. Version 6.0.1, 2010-06-28 Modified configuration scripts to allow building on OpenSUSE (and Ubuntu?) Version 6.0, 2010-06-25 Allow long options --help and --version. Using autoconf/automake. Version 5.8, 2010-04-10 Suppress ".tex" in the prompt. Version 5.7, 2010-04-05 Delete command can now delete more than one element/arrow. Turning off all pdflatex output. Version 5.6.1, 2010-03-26 Open tex_file for writing before restoring from backup. Version 5.6, 2010-03-25 Modified chmod system calls to be compatible with cygwin on Windows fat32. Closing the tex_file before processing it (needed for Windows). Simplified the log-output generation if processing fails. Always use pdflatex because of automatic rotation in ps2pdf. Version 5.5, 2010-03-16 Added sleep(1) between initial generations of the pdf file. Removed all interactions before initial generation of pdf file. Removed the option of opening another tex file. Removed the automatic start-up of PDFVIEWER. Added PRIVATE (i.e., static) specifiers where appropriate. Version 5.4, 2009-11-12 Must re-open tex_file to regenerate it (!) Version 5.3, 2009-10-30 Use ps2pdf without attempting rotation correction when using latex, but, to allow for a script that tests for "Orientation: Landscape" in the ps file, if the environment variable PS2PDF is defined, its value is used in lieu of ps2pdf. Offer to quit if the user won't provide a file name. Allow for PAGER == most. Code clean-up, especially localizing many globals. Version 5.2, 2009-10-19 Corrected coding for new file name in open_tex_file. Version 5.1, 2009-10-01 Final processing no longer automatically uses LaTeX. Version 5.0, 2009-09-15 Replaced filename by basefilename and chartfilename to allow more than one document to share an included chart file and allow more than one chart to be included in a document. The *file* command has been removed. Version 4.3, 2009-09-06 Replaced strlcpy and strlcpy by append (with offset). Introduced triv_type to avoid a "pedantic" error. Corrected an incorrect sizeof argument in open_tex_file. Call regenerate_and_process after a partial raise. Version 4.2, 2008-07-17 Use the /Orientation directive to gs (ghostscript) to ensure proper orientation when slanted fonts are used. Version 4.1, 2008-05-16 Implement shift/raise of specified diagram elements. Eliminate unnecessary dependence on libtermcap. Version 4.0.1, 2008-02-28 Corrected txt field of struct text to have size LINE_LEN+1 Version 4.0, 2008-02-13 Test for curvatures > 100. Implement \text command. Version 3.8.1, 2007-03-17 Sleep for KILL_WAIT seconds before terminating the pdf viewer. Version I.8, 2007-02-08 Semicolon appended to most user commands suppresses regeneration and reprocessing. ^C saves to file.tex. Use quit; to exit without saving. Final processing uses latex -> dvips -> ps2pdf to produce a smaller final pdf. Attempts to display the pdf during editing using value of environment variable PDFVIEWER. Version 3.7, 2006-12-27 latex->dvips->ps2pdf processing restored as an option. Warns about quitting with unpasted cuts. Version 3.6, 2006-11-29 Corrects two minor logical errors in code for arrow deletion and box editing. Generates progress messages when analyzing/saving/processing. Re-loads after every shell escape, so we can discard the Edit command. Applies shift/raise to cut and deleted nodes. Processes tex files using pdflatex instead of latex -> dvips -> ps2pdf. Version 3.5, 2006-11-20 simpler and more flexible implementation of cut/paste, delete/undelete generate undelete messages automatic re-generation and processing after editing operation Version 3.4, 2006-11-15 deal with files that are (initially) read-only deal with attempts to cut arrows Version 3.3, 2006-11-07 preserve comment lines within the chart environment correct option-handling bug introduced in 3.0 Version 3.2, 2006-11-03 Version 3.1, 2006-10-29 introduce Edit command restore write-access to TeX file during Edit or shell-command execution try to display error message in log file if LaTeX processing fails Version 3.0, 2006-10-19 replaced calls to make file.pdf by successive calls to latex, dvips, ps2pdf removed all references to pdf viewer, user must start one him/herself replaced strncpy/cat by strlcpy/cat (my implementation of the OpenBSD functions) produce warning message for truncated course code, timetable, title Version 2.4, 2006-04-12 added undelete command no warnings using -Wall -Wextra allow for cut/paste of minis that are targets of arrow test for non-existence of source/target box/mini for new arrow handle more signals than SIGINT (such as SIGSEGV) Version 2.3, 2006-03-23 remove "which" checking of pdfviewer to allow, e.g., xpdf -remote label use geometry.sty for new blank TeX file declarations of optarg, optind moved to prerex.h Version 2.2.2, 2006-03-08 Free linked structures and readline strings. Turn grid off initially before restoring a backup. Version 2.2.1, 2006-02-18 Don't try to remove/restore access to an empty filename. Version 2.2, 2006-02-15 Inputs and outputs \begin{chart} ... \end{chart} instead of \chart{ ... } Version 2.1.1, 2006-02-13 Add designation PRIVATE ( = static) to definitions of functions and variables. Version 2.1, 2006-02-09 Trap SIGINT in order to restore write-access after ^C. Add Backup command. Version 2.0.3, 2006-02-07 New arrow should have default curvature. Version 2.0.1, 2006-02-06 Free list structures before Restoring. Version 2.0, 2006-02-03 Partition into separate modules prerex.c, inout.c, edit.c Version 1.2.2, 2006-02-02 Cleanup curvature code. Use %s to output % in regenerate_tex_file. Version 1.2.1, 2006-02-02 Allow for curved recommended and co-requisite arrows. Version 1.2.0, 2006-02-01 Restore command. Version 1.1.2, 2006-01-31 Create backup of Tex file before editing. Re-open TeX file for writing before regenerating. Version 1.1.1, 2006-01-30 TeX file read-only during editing (except when re-generating it). Version 1.1.0, 2006-01-29 Corrected use of cut stacks. Eliminated cut arrow command. Introduced delete box/mini and delete arrow. Checked for duplicate boxes, minis or arrows (e.g., when pasting). Version 1.0.5, 2006-01-28 Keep stacks of cut boxes, minis, and arrows. Version 1.0.4, 2006-01-27 Add option -p. Version 1.0.3, 2006-01-26 Replace system calls to "xpdf" by calls to pdfviewer (if defined). Version 1.0.2, 2006-01-25 Replace system call to "pdflatex filename" by call to "make filename.pdf" to provide more flexibility (e.g., LaTeX vs pdfLaTeX). Version 1.0.1, 2006-01-24 Error message for pdflatex failure now refers to filename.log. Inserted checks for lp or cp increasing too far in read_textfield and read_bracketed_textfield.

Courses are either .I half or .I full, and may be .I required or .I optional (or neither). Each course box can contain a course .I code (upper left corner), a course .I title (lower half), and .I timetable information (upper right corner). An arrow can be either a .I prerequisite (solid), a .I corequisite (dotted), or .I recommended (dashed). When a conventional arrow would be inappropriate, a .I mini course just above a target box can be used. .SH STRUCTURE The file should contain exactly one instance of a LaTeX environment .P .BI \ebegin{chart} " instruction ... " \eend{chart} .P with at most one .I instruction per line. Note that a program such as .BR prerex (1) analyzes prerex-format files .I without using TeX; for example, macro definitions will be ignored and macro calls will not be expanded. .PP Instructions may be preceded by white space. Lines that start with % are treated as comments and ignored. The order of instructions is not significant except that the instruction for the source and target box o an arrow should .I precede the instruction for the arrow. The instruction formats are described in the following sections. .SH COURSE BOXES The instructions producing course boxes have the following forms: .HP .BI \ehalfcourse " x,y" :{ code }{ title }{ timetable } .HP .BI \efullcourse " x,y" :{ code }{ title }{ timetable } .HP .BI \ereqhalfcourse " x,y" :{ code }{ title }{ timetable } .HP .BI \ereqfullcourse " x,y" :{ code }{ title }{ timetable } .HP .BI \eopthalfcourse " x,y" :{ code }{ title }{ timetable } .HP .BI \eoptfullcourse " x,y" :{ code }{ title }{ timetable } .LP where .I x,y are the coordinates of the .I centerpoint of the box, relative to the origin of the coordinate system at the lower-left corner of the diagram. The .I code, .I title, and .I timetable arguments are arbitrary (well-bracketed) text, possibly with LaTeX markup. The following are similar but take an additional argument to specify the (non-default) background color of the course box: .IP .BI \ehalfcoursec " x,y" :{ code }{ title }{ timetable }{ color } .IP .BI \efullcoursec " x,y" :{ code }{ title }{ timetable }{ color } .IP .BI \ereqhalfcoursec " x,y" :{ code }{ title }{ timetable }{ color } .IP .BI \ereqfullcoursec " x,y" :{ code }{ title }{ timetable }{ color } .IP .BI \eopthalfcoursec " x,y" :{ code }{ title }{ timetable }{ color } .IP .BI \eoptfullcoursec " x,y" :{ code }{ title }{ timetable }{ color } .LP .SH MINI COURSE BOXES AND TEXT A mini course is produced by an instruction of the form .HP .BI \emini " x,y" :{ code } .HP A text line is inserted into the chart by an instruction of the form .HP .BI \etext " x,y" :{ line-of-text } .HP The maximum allowed length of a course-code may be smaller that the maximum allowed for a line of text. .SH ARROWS Arrows between course boxes (or from a mini to a course box) are produced by instructions of the form .HP .BI \eprereq " x0,y0,x1,y1" : .HP .BI \ecoreq " x0,y0,x1,y1" : .HP .BI \erecomm " x0,y0,x1,y1" : .LP These produce, respectively, solid, dotted, and dashed arrows from the course box (or mini) centered at coordinates .I x0,y0 to the course box centered at coordinates .I x1,y1. .PP In some implementations, certain arrows by default have a non-zero curvature. It is possible to override the default curvature for a particular arrow by using the instructions .HP .BI \eprereqc " x0,y0,x1,y1;c" : .HP .BI \ecoreqc " x0,y0,x1,y1;c" : .HP .BI \erecommc " x0,y0,x1,y1;c" : .LP where .I c is an integer in the range 0-100 specifying the desired curvature; for example, .IR c= 0 will produce a .I straight arrow. To change the default curvature, the user program may redefine the .B \eDefaultCurvature command. .SH COORDINATE GRID The following instruction produces a coordinate grid, which is useful for editing a diagram: .HP .B \egrid .LP This is normally placed before all the other instructions so that grid lines are in the background, covered by course boxes, minis, and arrows. .SH WEB LINKS Course boxes may be linked to web addresses. The URL for course boxes may be set by the user by redefining the .B \eCourseURL command; when called for a course box, it is supplied with three arguments, the .I x and .I y coordinates of the box, mini, or textline, and the .I code argument of the course box. For example, .HP .B \erenewcommand{\eCourseURL}[3]{http://www.cs.queensu.ca/undergraduate/courses/#3.html} .LP is appropriate for courses at the School of Computing, Queen's University. The first two arguments can be used to display the coordinates of a box, mini, or textline in some PDF viewers while the mouse hovers over it when the source file is being edited. .SH AUTHOR R. D.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.

These may be available packaged for your Linux distribution or the sources can be obtained from: http://qt.nokia.com/downloads/downloads#lgpl http://poppler.freedesktop.org/ + Edit vprerex.pro so INCLUDEPATH and LIBS point to the relevant directories. + qmake vprerex.pro (using the Qt-4 qmake) + make + install the vprerex binary in a suitable directory such as $HOME/bin or /usr/local/bin. If vprerex is applied to a LaTeX file, it calls xterm and prerex. On the Windows platform, the Qt-4 libraries are available for the Cygwin environment and the poppler libraries (including poppler-qt4) will build in this environment.

Version 6.3.2 2012-03-30 - bump up version number to match prerex.sty and prerex Version 6.3.1 2011-12-22 If a file opening dialogue is used and a tex file is opened, the Working Directory for the prerex process is set to the directory of the tex file. Version 6.3 2011-11-22 Right-clicking on a course box or arrow *appends* coordinates to the clipboard (to simplify multiple deletes/shifts). Version 6.2 2011-09-08 no longer embedding the prerex editing window because of continuing focus issues Version 6.1.1 2011-08-20 - using grabKeyboard to avoid keyboard-focus issues - bump up version number to match prerex.sty and prerex Version 6.0.1 2011-07-27 - modified FocusPolicy Version 6.0 2010-06-23 - files re-organized and distributed as a gzipped tarball Version 5.7 2010-04-06 - corrected coordinate calculations to use the image width/height rather than the widget width/height (and allow for image offsets) Version 5.6 2010-03-26 Version 5.5 2010-03-16 - re-named vprerex (visual prerex) - opens prerex source files by embedding a prerex command-line window - added Quit button to controls - removed docking features from the controls widget - removed resizing from the statusbar This is the first distributed version of vprerex; the version numbers are starting at 5.5 to be compatible with the current version of prerex. Derived from pdfviewer by - excising all UI widgets except the Page spinner and the Scale selector - adding URI tooltips and cursor-shape changes for links - assigning box, edge, and background-point coordinates to the X clipboard when the user clicks on a box, edge mid-point, or background point, resp. (for a prerex chart with the coordinate grid enabled) - adding a file watcher to re-load the PDF when the file changes - posting taskbar messages to identify the program version and the loaded file, and inform the user that the PDF has been re-loaded prerex-6.4.0/vprerex-6.4.0/vprerex.pro0000644000123700002140000000061211737043604015543 0ustar rdtrdtFORMS = window.ui HEADERS = documentwidget.h \ window.h SOURCES = documentwidget.cpp \ main.cpp \ window.cpp # Modify these to refer to the directories on your system # that contain the poppler-qt4.h header file and [lib]poppler-qt4 library.

The viewer may be used just as a minimalistic viewer of arbitrary PDF files but supports editing of charts generated using .BR prerex.sty (7) by allowing coordinates of course boxes, arrows, and background points to be conveyed back to the .BR prerex (1) command-line using the clipboard. .SH USAGE If .B vprerex is invoked on a PDF file, it simply displays that file. .PP If the (first) argument does .I not have the .pdf suffix, it is assumed to be the base file for a LaTeX document containing a prerequisite-chart description in .BR prerex (5) format, to be edited using .BR prerex (1). If a .I second argument is supplied, it is regarded as an included file containing the specific chart environment to be edited. .PP If .I no arguments are supplied, a file-opening dialog allows the user the specify the .BR prerex (1) base file to be edited (or the PDF file to be viewed); if a separate chartfile is needed, .BR vprerex (1) must be invoked wth two arguments on the command line. .PP If the mouse hovers over a hyperlink in the PDF viewing window, the cursor shape will change to a pointing finger and a tooltip will display the URI. If the PDF file displayed contains a chart generated using .BR prerex.sty (7) and the background coordinate grid has been enabled, left-clicking the mouse on a course box, arrow mid-point, or background point will load the relevant coordinates into the X clipboard; right-clicking the mouse on a course box or arrow will .I append the relevant coordinates to the clipboard. The cursor shape changes to a plus-sign to indicate successful capture of the coordinates. Middle-clicking the mouse at the .BR prerex (1) command-line will then paste those coordinates into a command being composed. If the chart file is regenerated, the updated document will be re-loaded. .SH DEPENDENCIES .B vprerex is based on the Qt-4 library. It calls .BR xterm (1) and .BR prerex (1) for the editing window and uses .BR poppler-qt4 for rendering PDF files. .SH AUTHOR R. D.
