After many -% attempts to reach him had failed, Hendri Adriaens took over maintenance of -% the package in accordance with the LPPL's procedure for abandoned packages. -% He then passed the maintainership of the package to Brooks Moses, who had -% volunteered for the position while this procedure was going through. -% -% This release, version 1.3c, is not yet a long-awaited bugfix release, as I -% have neither a list of bugs that have been reported since 1.3b, nor a good -% comprehensive test suite to make sure that my fixes don't break things. -% (It does have some very minor corrections to the Erlang and Octave language -% definitions that were reported to the Debian bug system, and a minor -% internal spped improvement placed in \texttt{lstpatch.sty}, but other than that -% the only changes are the alteration of the maintanence information and the -% inclusion of this prefatory note.) I would very much appreciate it if users -% would email any outstanding bug reports to me at \lstemail, along with any -% examples of tricky uses of the package that should be included in the test -% suite. -% -% \paragraph{Reading this manual} -% If you are experienced with the \packagename{listings} package, you should -% read the next paragraph ``\emph{News and changes}''. Otherwise read section -% \lstref{uGettingStarted} step by step and go on with section -% \ref{uTheNextSteps}. -% -% \paragraph{News and changes} -% Version 1.3 is the third bugfix release. The most noteworthy news for the -% tortured\,---\,I mean experienced\,---\,user is a new |\output| routine, -% which improves the compatibility to other packages. Therefore the temporary -% key |noxoutput| has been removed. -% -% |texcs| became a family, i.e.~you can highlight your own control sequences -% diffently from the already defined ones: |texcsstyle=|[|*|]\oarg{class number}\ldots\space -% and |texcs=|\oarg{classnumber}\ldots\space -% Note the added optional star, which also highlights the backslash in front of -% the control sequence name.

You need not to be an expert. -% Here is a minimal file for \packagename{listings}. -% \begin{verbatim} -% \documentclass{article} -% \usepackage{listings} -% -% \begin{document} -% \lstset{language=Pascal} -% -% % Insert Pascal examples here. -% -% \end{document}\end{verbatim} -% Now type in this first example and run it through \LaTeX. -% \begin{advise} -% \item Must I do that really? -% \advisespace -% Yes and no. Some books about programming say this is good. -% What a mistake! Typing takes time---wasted if the code is clear to -% you. And if you need that time to understand what is going on, the -% author of the book should reconsider the concept of presenting the -% crucial things---you might want to say that about this guide even---or -% you're simply unexperienced with programming. If only the latter case -% applies, you should spend more time on reading (good) books about -% programming, (good) documentations, and (good) source code from other -% people. Of course you should also make your own experiments. -% You will learn a lot. However, running the example through \LaTeX\ -% shows whether the \packagename{listings} package is installed. -% \item The example doesn't work. -% \advisespace -% Are the two packages \packagename{listings} and \packagename{keyval} -% installed on your system? Consult the administration tool of your -% \TeX\ distribution, your system administrator, the local \TeX\ and -% \LaTeX\ guides, a \TeX\ FAQ, and section \ref{rInstallation}---in -% the given order. If you've checked \emph{all} these sources and are -% still helpless, you might want to write a post to a \TeX\ newsgroup -% like \texttt{comp.text.tex}. -% \item Should I read the software license before using the package? -% \advisespace -% Yes, but read this \emph{Getting started} section first to decide -% whether you are willing to use the package.^^A ;-) -% \end{advise} -% -% -% \subsection{Typesetting listings} -% -% Three types of source codes are supported: code snippets, code segments, and -% listings of stand alone files; snippets are placed inside paragraphs and the -% others as separate paragraphs---the difference is the same as between text -% style and display style formulas. -% \begin{advise} -% \item No matter what kind of source you have, if a listing contains national -% characters like \'e, \L, \"a, or whatever, you must tell it the -% package! Section \lstref{uSpecialCharacters} discusses this issue. -% \end{advise} -% -% \paragraph{Code snippets} -% The well-known \LaTeX\ command |\verb| typesets code snippets verbatim. -% The new command |\lstinline| pretty-prints the code, for example -%`\lstinline!var i:integer;!' is typeset by -%`{\rstyle|\lstinline|}|!var i:integer;!|'. The exclamation marks delimit -% the code and can be replaced by any character not in the code; -% |\lstinline$var i:integer;$| gives the same result. -% -% \paragraph{Displayed code} -% The \texttt{lstlisting} environment typesets the enclosed source code. Like -% most examples, the following one shows verbatim \LaTeX\ code on the right -% and the result on the left. You might take the right-hand side, put it into -% the minimal file, and run it through \LaTeX. -% \begin{lstsample}[lstlisting]{}{} -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% It can't be easier. -% \begin{advise} -% \item That's not true. The name `\texttt{listing}' is shorter. -% \advisespace -% Indeed. But other packages already define environments with that name. -% To be compatible with such packages, all commands and environments of -% the \packagename{listings} package use the prefix `\texttt{lst}'. -% \end{advise} -% The environment provides an optional argument. It tells the package to -% perform special tasks, for example, to print only the lines 2--5: -% \begin{lstsample}{\lstset{frame=trbl,framesep=0pt}\label{gFirstKey=ValueList}}{} -% \begin{lstlisting}[firstline=2, -% lastline=5] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item Hold on! Where comes the frame from and what is it good for? -% \advisespace -% You can put frames around all listings except code snippets. -% You will learn it later. The frame shows that empty lines at the end -% of listings aren't printed. This is line 5 in the example. -% \item Hey, you can't drop my empty lines! -% \advisespace -% You can tell the package not to drop them: -% The key `\ikeyname{showlines}' controls these empty lines and is -% described in section \ref{rTypesettingListings}. Warning: First -% read ahead on how to use keys in general. -% \item I get obscure error messages when using `\ikeyname{firstline}'. -% \advisespace -% That shouldn't happen. Make a bug report as described in section -% \lstref{uTroubleshooting}. -% \end{advise} -% -% \paragraph{Stand alone files} -% Finally we come to |\lstinputlisting|, the command used to pretty-print -% stand alone files. It has one optional and one file name argument. -% Note that you possibly need to specify the relative path to the file. -% Here now the result is printed below the verbatim code since both together -% don't fit the text width. -% \begin{lstsample}{\lstset{comment=[l]\%,columns=fullflexible}}{\lstset{alsoletter=\\,emph=\\lstinputlisting,emphstyle=\rstyle}\lstaspectindex{\lstinputlisting}{}} -% \lstinputlisting[lastline=4]{listings.sty} -% \end{lstsample} -% \begin{advise} -% \item The spacing is different in this example. -% \advisespace -% Yes. The two previous examples have aligned columns, i.e.~columns with -% identical numbers have the same horizontal position---this package -% makes small adjustments only. The columns in the example here are not -% aligned. This is explained in section \ref{uFixedAndFlexibleColumns} -% (keyword: full flexible column format). -% \end{advise} -% -% Now you know all pretty-printing commands and environments. It remains -% to learn the parameters which control the work of the \packagename{listings} -% package. This is, however, the main task. Here are some of them. -% -% -% \subsection{Figure out the appearance}\label{gFigureOutTheAppearance} -% -% Keywords are typeset bold, comments in italic shape, and spaces in strings -% appear as \textvisiblespace.

In general, the \emph{very last} command might read exactly one -% argument, namely some material the package typesets. There's one exception. -% The last command of \ikeyname{basicstyle} \emph{must not} read any -% tokens---or you will get deep in trouble. -% \begin{advise} -% \item `|basicstyle=\small|' looks fine, but comments look really bad with -% `|commentstyle=\tiny|' and empty basic style, say. -% \advisespace -% Don't use different font sizes in a single listing. -% \item But I really want it! -% \advisespace -% No, you don't. -%^^A The package adjusts internal data after selecting the basic style at -%^^A the beginning of each listing. This is a problem if you change the -%^^A font size for comments or strings, for example. -%^^A Section \ref{rColumnAlignment} shows how to overcome this. -%^^A But once again: Don't use different font sizes in a single listing -%^^A unless you really know what you are doing. -% \end{advise} -% -% \paragraph{Warning}\label{wStrikingStyles} -% You should be very careful with striking styles; the recent example is rather -% moderate---it can get horrible. \emph{Always use decent highlighting.} -% Unfortunately it is difficult to give more recommendations since they depend -% on the type of document you're creating. Slides or other presentations often -% require more striking styles than books, for example. -% In the end, it's \emph{you} who have to find the golden mean! -% -% -% \subsection{Seduce to use}\label{gSeduceToUse} -% -% You know all pretty-printing commands and some main parameters. Here now -% comes a small and incomplete overview of other features. The table of -% contents and the index also provide information. -% -% \paragraph{Line numbers} -% are available for all displayed listings, e.g.~tiny numbers on the left, each -% second line, with 5pt distance to the listing: -% \begin{lstxsample}[numbers,numberstyle,stepnumber,numbersep] -% \lstset{numbers=left, numberstyle=\tiny, stepnumber=2, numbersep=5pt} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item I can't get rid of line numbers in subsequent listings. -% \advisespace -% `|numbers=none|' turns them off. -% \item Can I use these keys in the optional arguments? -% \advisespace -% Of course. Note that optional arguments modify values for one -% particular listing only: you change the appearance, step or distance -% of line numbers for a single listing. The previous values are -% restored afterwards. -% \end{advise} -% The environment allows you to interrupt your listings: you can end a listing -% and continue it later with the correct line number even if there are other -% listings in between. Read section \ref{uLineNumbers} for a thorough -% discussion. -% -% \paragraph{Floating listings} -% Displayed listings may float: -% \begin{lstsample}{\lstset{frame=tb}}{} -% \begin{lstlisting}[float,caption=A floating example] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% Don't care about the parameter \ikeyname{caption} now. And if you put the -% example into the minimal file and run it through \LaTeX, please don't wonder: -% you'll miss the horizontal rules since they are described elsewhere. -% \begin{advise} -% \item \LaTeX's float mechanism allows to determine the placement of floats. -% What's about that? -% \advisespace -% You can write `|float=tp|', for example. -% \end{advise} -% -% \paragraph{Other features} -% There are still features not mentioned so far: automatic breaking of long -% lines, the possibility to use \LaTeX\ code in listings, automated indexing, -% or personal language definitions. -% One more little teaser? Here you are. But note that the result is not -% produced by the \LaTeX\ code on the right alone. The main parameter is -% hidden. -% \begin{lstsample}{\lstset{literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1}}{} -% \begin{lstlisting} -% if (i<=0) then i := 1; -% if (i>=0) then i := 0; -% if (i<>0) then i := 0; -% \end{lstlisting} -% \end{lstsample} -% -% You're not sure whether you should use \packagename{listings}? -% Read the next section! -% -% -% \subsection{Alternatives} -% -% \begin{advise} -% \item Why do you list alternatives? -% \advisespace -% Well, it's always good to know the competitors.^^A :-) -% \item I've read the descriptions below and the \packagename{listings} package -% seems to incorporate all the features. Why should I use one of the -% other programs? -% \advisespace -% Firstly, the descriptions give a taste and not a complete overview, -% secondly, \packagename{listings} lacks some properties, and, eventually, -% you should use the program matching your needs most precisely. -% \end{advise} -% This package is certainly not the final utility for typesetting source code. -% Other programs do their job very well---if you are not satisfied with -% \packagename{listings}. Some are independent of \LaTeX, other come as -% separate program plus \LaTeX\ package, and other more are packages which -% don't pretty-print the source code. The second type inlcudes converters, -% cross compilers, and preprocessors. Such programs create \LaTeX\ files -% you can use in your document or stand alone ready-to-run \LaTeX\ files. -% -% Note that I'm not dealing with any literate programming tool here, which -% could also be an alternative. However, you should have heard of the -% \texttt{WEB} system, the tool Prof.~Donald E.~Knuth developed and made use -% of to document and implement \TeX. -% -% \paragraph{\href{http://www.infres.enst.fr/~demaille/a2ps}{\packagename{a2ps}}} -% started as `ASCII to PostScript' converter, but today you can invoke the -% program with \texttt{--pretty-print=}\meta{language} option. If your -% favourite programming language is not already supported, you can write your -% own so-called style sheet. You can request line numbers, borders, headers, -% multiple pages per sheet, and many more. You can even print symbols like -% $\forall$ or $\alpha$ instead of their verbose forms. If you just want -% program listings and not a document with some listings, this is the best -% choice. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/nonfree/support/lgrind}{\packagename{LGrind}}} -% is a cross compiler and comes with many predefined programming languages. -% For example, you can put the code on the right in your document, invoke -% \packagename{LGrind} with \texttt{-e} option (and file names), and run the -% created file through \LaTeX. You should get a result similar to the -% left-hand side: -% \begin{center} -% \begin{minipage}{0.45\linewidth} -%\iflgrind -% \LGindent=0pt -% \LGinlinefalse\LGbegin\lgrinde -% \L{\LB{\K{for}_\V{i}:=\V{maxint}_\K{to}_\N{0}_\K{do}}} -% \L{\LB{\K{begin}}} -% \L{\LB{____\C{}\{_do_nothing_\}\CE{}}} -% \L{\LB{\K{end};}} -% \L{\LB{}} -% \L{\LB{\V{Write}(\S{}{'}Case_insensitive_{'}\SE{});}} -% \L{\LB{\V{WritE}(\S{}{'}Pascal_keywords.{'}\SE{});}} -% \endlgrinde\LGend -%\else -% \packagename{LGrind} not installed. -%\fi -% \end{minipage} -% \begin{minipage}{0.45\linewidth} -% \begin{verbatim} -% %[ -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% %]\end{verbatim} -% \end{minipage} -% \end{center} -% If you use |%(| and |%)| instead of |%[| and |%]|, you get a code snippet -% instead of a displayed listing. Moreover you can get line numbers to the -% left or right, use arbitrary \LaTeX\ code in the source code, print symbols -% instead of verbose names, make font setup, and more. You will (have to) -% like it (if you don't like \packagename{listings}). -% -% Note that \packagename{LGrind} contains code with a no-sell license and is -% thus nonfree software. -% -% \paragraph{\href{ftp://axp3.sv.fh-mannheim.de/cvt2latex}{\packagename{cvt2ltx}}} -% is a family of `source code to \LaTeX' converters for C, Objective C, \Cpp, -% IDL and Perl. Different styles, line numbers and other qualifiers can be -% chosen by command-line option. Unfortunately it isn't documented how other -% programming languages can be added. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/support/C++2LaTeX-1_1pl1}{\packagename{\Cpp2\LaTeX}}} -% is a C/\Cpp\ to \LaTeX\ converter. You can specify the fonts for comments, -% directives, keywords, and strings, or the size of a tabulator. But as far as -% I know you can't number lines. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/support/slatex}{\packagename{S\LaTeX}}} -% is a pretty-printing Scheme program (invokes \LaTeX\ automatically) -% especially designed for Scheme and other Lisp dialects. It supports stand -% alone files, text and display listings, and you can even nest the -% commands/environments if you use \LaTeX\ code in comments, for example. -% Keywords, constants, variables, and symbols are definable and use of -% different styles is possible. No line numbers. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/support/tiny_c2l}{\packagename{tiny\textunderscore c2ltx}}} -% is a C/\Cpp/Java to \LaTeX\ converter based on \packagename{cvt2ltx} (or the -% other way round?). It supports line numbers, block comments, \LaTeX\ code -% in/as comments, and smart line breaking. Font selection and tabulators are -% hard-coded, i.e.~you have to rebuild the program if you want to change the -% appearance. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/misc}{\packagename{listing}}} -% ---note the missing \packagename{s}---is not a pretty-printer and the -% aphorism about documentation at the end of \texttt{listing.sty} is not -% true.\space ^^A :-) -% It defines |\listoflistings| and a nonfloating environment for listings. -% All font selection and indention must be done by hand. However, it's -% useful if you have another tool doing that work, e.g.~\packagename{LGrind}. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/alg}{\packagename{alg}}} -% provides essentially the same functionality as \packagename{algorithms}. -% So read the next paragraph and note that the syntax will be different. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/algorithms}{\packagename{algorithms}}} -% goes a quite different way. You describe an algorithm and the package -% formats it, for example -% \begin{center} -% \begin{minipage}{0.45\linewidth} -%\ifalgorithmic -% \begin{algorithmic} -% \IF {$i\leq0$} -% \STATE $i\gets1$ -% \ELSE\IF {$i\geq0$} -% \STATE $i\gets0$ -% \ENDIF\ENDIF -% \end{algorithmic} -%\else -% \packagename{algorithms} not installed. -%\fi -% \end{minipage} -% \begin{minipage}{0.45\linewidth} -% \begin{verbatim} -%\begin{algorithmic} -%\IF{$i\leq0$} -%\STATE $i\gets1$ -%\ELSE\IF{$i\geq0$} -%\STATE $i\gets0$ -%\ENDIF\ENDIF -%\end{algorithmic}\end{verbatim} -% \end{minipage} -% \end{center} -% As this example shows, you get a good looking algorithm even from a bad -% looking input. The package provides a lot more constructs like |for|-loops, -% |while|-loops, or comments. You can request line numbers, `ruled', `boxed' -% and floating algorithms, a list of algorithms, and you can customize the -% terms \textbf{if}, \textbf{then}, and so on. -% -% \paragraph{\href{http://www.mimuw.edu.pl/~wolinski/pretprin.html}{\packagename{pretprin}}} -% is a package for pretty-printing texts in formal languages---as the title -% in TUGboat, Volume 19 (1998), No.~3 states. It provides environments which -% pretty-print \emph{and} format the source code. Analyzers for Pascal and -% Prolog are defined; adding other languages is easy---if you are or get a bit -% familiar with automatons and formal languages. -% -% \paragraph{\packagename{alltt}} -% defines an environment similar to \texttt{verbatim} except that |\|, |{| and -% |}| have their usual meanings. This means that you can use commands in the -% verbatims, e.g.~select different fonts or enter math mode. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/moreverb}{\packagename{moreverb}}} -% requires \packagename{verbatim} and provides verbatim output to a file, -% `boxed' verbatims and line numbers. -% -% \paragraph{\packagename{verbatim}} -% defines an improved version of the standard \texttt{verbatim} environment and -% a command to input files verbatim. -% -% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/fancyvrb}{\packagename{fancyvrb}}} -% is, roughly spoken, a super set of \packagename{alltt}, -% \packagename{moreverb}, and \packagename{verbatim}, but many more parameters -% control the output. The package provides frames, line numbers on the left or -% on the right, automatic line breaking (difficult), and more. For example, an -% interface to \packagename{listings} exists, i.e.~you can pretty-print source -% code automatically. -% The package \packagename{fvrb-ex} builds above \packagename{fancyvrb} and -% defines environments to present examples similar to the ones in this guide. -% -% -% \section{The next steps}\label{uTheNextSteps} -% -% Now, before actually using the \packagename{listings} package, you should -% \emph{really} read the software license. It does not cost much time and -% provides information you probably need to know. -% -% -% \subsection{Software license}\label{uSoftwareLicense} -% -% The files \texttt{listings.dtx} and \texttt{listings.ins} and all -% files generated from only these two files are referred to as `the -% \packagename{listings} package' or simply `the package'. -% \texttt{lstdrvrs.dtx} and the files generated from that file are -% `drivers'. -% -% \paragraph{Copyright} -% The \packagename{listings} package is copyright 1996--2004 Carsten Heinz, -% and copyright 2006 Brooks Moses. The drivers are copyright any individual -% author listed in the driver files. -% -% \paragraph{Distribution and modification} -% The \packagename{listings} package and its drivers may be distributed -% and/or modified under the conditions of the LaTeX Project Public License, -% either version 1.3 of this license or (at your option) any later version. -% The latest version of this license is in -% \href{http://www.latex-project.org/lppl.txt}{http://www.latex-project.org/lppl.txt} -% and version 1.3 or later is part of all distributions of LaTeX version -% 2003/12/01 or later. -% -% \paragraph{Contacts} -% Read section \lstref{uTroubleshooting} on how to submit a bug report. -% Send all other comments, ideas, and additional programming languages to -% \lstemail\ using \texttt{listings} as part of the subject. -% -% -% \subsection{Package loading}\label{uPackageLoading} -% -% As usual in \LaTeX, the package is loaded by -% |\usepackage[|\meta{options}|]{listings}|, -% where |[|\meta{options}|]| is optional and gives a comma separated list of -% options. Each either loads an additional \packagename{listings} aspect, or -% changes default properties. Usually you don't have to take care of such -% options. But in some cases it could be necessary: if you want to compile -% documents created with an earlier version of this package or if you use -% special features. Here's an incomplete list of possible options. -% \begin{advise} -% \item Where is a list of all options? -% \advisespace -% In the developer's guide since they were introduced to debug the -% package more easily. Read section \ref{uHowTos} on how to get that -% guide. -% \end{advise} -% \begin{description} -% \item[\normalfont\texttt{0.21}]\leavevmode -% -% compiles a document created with version 0.21. -% -% \item[\normalfont\texttt{draft}]\leavevmode -% -% The package prints no stand alone files, but shows the captions and -% defines the corresponding labels. -% Note that a global |\documentclass|-option \texttt{draft} is -% recognized, so you don't need to repeat it as a package option. -% -% \item[\normalfont\texttt{final}]\leavevmode\label{uoption:final} -% -% Overwrites a global \texttt{draft} option. -% -% \item[\normalfont\texttt{savemem}]\leavevmode -% -% tries to save some of \TeX's memory. If you switch between languages -% often, it could also reduce compile time. But all this depends on the -% particular document and its listings. -% \end{description} -% Note that various experimental features also need explicit loading via -% options. Read the respective lines in section \ref{rExperimentalFeatures}. -% -% \medbreak -% After package loading it is recommend to load all used dialects of programming -% languages with the following command. It is faster to load several languages -% with one command than loading each language on demand. -% \begin{syntax} -% \item {\rstyle\icmdname\lstloadlanguages}\marg{comma separated list of languages} -% -% Each language is of the form \oarg{dialect}\meta{language}. Without -% the optional \oarg{dialect} the package loads a default dialect. So -% write `|[Visual]C++|' if you want Visual \Cpp\ and `|[ISO]C++|' for -% ISO \Cpp. Both together can be loaded by the command -% |\lstloadlanguages{[Visual]C++,[ISO]C++}|. -% -% Table \ref{uPredefinedLanguages} on page \pageref{uPredefinedLanguages} -% shows all defined languages and their dialects. -% \end{syntax} -%^^A After or even before language loading, you might want to define default -%^^A dialects---just to be independent of configuration files. -% -% -% \subsection{The key=value interface}\label{uTheKey=ValueInterface} -% -% This package uses the \packagename{keyval} package from the -% \packagename{graphics} bundle by David Carlisle. Each parameter is -% controlled by an associated key and a user supplied value. For example, -% \ikeyname{firstline} is a key and |2| a valid value for this key. -% -% The command {\rstyle\icmdname\lstset} gets a comma separated list of -% ``key|=|value'' pairs. The first list with more than a single entry is on -% page \pageref{gFirstKey=ValueList}: |firstline=2,lastline=5|. -% \begin{advise} -% \item So I can write `|\lstset{firstline=2,lastline=5}|' once for all? -% \advisespace -% No. `\ikeyname{firstline}' and `\ikeyname{lastline}' belong to a small -% set of -% keys which are used on individual listings. However, your command is -% not illegal---it has no effect. You have to use these keys inside the -% optional argument of the environment or input command. -% \item What's about a better example of a key|=|value list? -% \advisespace -% There is one in section \ref{gFigureOutTheAppearance}. -% \item `|language=[77]Fortran|' does not work inside an optional argument. -% \advisespace -% You must put braces around the value if a value with optional argument -% is used inside an optional argument. In the case here write -% `|language={[77]Fortran}|' to select Fortran 77. -% \item If I use the `\ikeyname{language}' key inside an optional argument, the -% language isn't active when I typeset the next listing. -% \advisespace -% All parameters set via `|\lstset|' keep their values up to the end of -% the current environment or group. Afterwards the previous values are -% restored. The optional parameters of the two pretty-printing commands -% and the `\texttt{lstlisting}' environment take effect on the particular -% listing only, i.e.~values are restored immediately. For example, you -% can select a main language and change it for special listings. -% \item \icmdname\lstinline\ has an optional argument? -% \advisespace -% Yes. And from this fact comes a limitation: you can't use the left -% bracket `|[|' as delimiter except you specify at least an empty -% optional argument as in `|\lstinline[][var i:integer;[|'. -% If you forget this, you will either get a ``runaway argument'' error -% from \TeX, or an error message from the \packagename{keyval} package. -% \end{advise} -% -% -% \subsection{Programming languages}\label{uProgrammingLanguages} -% -% You already know how to activate programming languages---at least Pascal. -% An optional parameter selects particular dialects of a language. For example, -% |language=[77]Fortran| selects Fortran 77 and |language=[XSC]Pascal| does the -% same for Pascal XSC. The general form is -% {\rstyle\ikeyname{language}}|=|\oarg{dialect}\meta{language}. -% If you want to get rid of keyword, comment, and string detection, use -% |language={}| as argument to |\lstset| or as optional argument. -% -% Table \ref{uPredefinedLanguages} shows all predefined languages and dialects. -% Use the listed names as \meta{language} and \meta{dialect}, respectively. If -% no dialect or `empty' is given in the table, just don't specify a dialect. -% Each underlined dialect is default; it is selected if you leave out -% the optional argument.

So you only have to write a -% language definition for your assembler dialect, which doesn't interfere -% with the definition of C, say. Moreover you might want to use the key -% `\keyname{classoffset}' described in section \ref{rLanguagesAndStyles}. -% \item How can I define my own language? -% \advisespace -% This is discussed in section \ref{rLanguageDefinitions}. And if you -% think that other people could benefit by your definition, you might -% want to send it to the address in section \ref{uSoftwareLicense}. -% Then it will be published under the \LaTeX\ Project Public License. -% \end{advise} -% Note that the arguments \meta{language} and \meta{dialect} are case -% insensitive and that spaces have no effect. -% -% -% \subsection{Special characters}\label{uSpecialCharacters} -% -% -% \paragraph{Tabulators} -% You might get unexpected output if your sources contain tabulators. -% The package assumes tabulator stops at columns 9, 17, 25, 33, and so on. -% This is predefined via |tabsize=8|. If you change the eight to the number -% $n$, you will get tabulator stops at columns $n+1,2n+1,3n+1,$ and so on. -% \begin{lstsample}[tabsize]{}{} -% \lstset{tabsize=2} -% \begin{lstlisting} -% 123456789 -% { one tabulator } -% { two tabs } -% 123 { 123 + two tabs } -% \end{lstlisting} -% \end{lstsample} -% For better illustration, the left-hand side uses |tabsize=2| but the verbatim -% code |tabsize=4|. Note that |\lstset| modifies the values for all following -% listings in the same environment or group. This is no problem here since the -% examples are typeset inside minipages. If you want to change settings for a -% single listing, use the optional argument. -% -% -% \paragraph{Visible tabulators and spaces} -% One can make spaces and tabulators visible: -% \begin{lstsample}[showspaces,showtabs,tab]{}{} -% \lstset{showspaces=true, -% showtabs=true, -% tab=\rightarrowfill} -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% If you request \ikeyname{showspaces} but no \ikeyname{showtabs}, -% tabulators are converted to visible spaces. -% The default definition of \ikeyname{tab} produces a `wide visible space' -% \lstinline[showtabs]! !. So you might want to use |$\to$|, |$\dashv$| -% or something else instead. -% \begin{advise} -% \item Some sort of advice: (1) You should really indent lines of source code -% to make listings more readable. (2) Don't indent some lines with -% spaces and others via tabulators. Changing the tabulator size (of your -% editor or pretty-printing tool) completely disturbs the columns. -% (3) As a consequence, never share your files with differently tab sized -% people!^^A true only if you use tabulators, just :-) -% \item To make the \LaTeX\ code more readable, I indent the environments' -% program listings. How can I remove that indention in the output? -% \advisespace -% Read `How to gobble characters' in section \ref{uHowTos}. -% \end{advise} -% -% -% \paragraph{Form feeds} -% Another special character is a form feed causing an empty line by default. -% {\rstyle\ikeyname{formfeed}}|=\newpage| would result in a new page every -% form feed. Please note that such definitions (even the default) might get -% in conflict with frames. -% -% -% \paragraph{National characters} -% If you type in such characters directly as characters of codes 128--255 and -% use them also in listings, let the package know it---or you'll get really -% funny results. {\rstyle\ikeyname{extendedchars}}|=true| allows and -% |extendedchars=false| prohibits extended characters in listings. If you use -% them, you should load \packagename{fontenc}, \packagename{inputenc} and/or -% any other package which defines the characters. -% \begin{advise} -% \item I have problems using \packagename{inputenc} together with -% \packagename{listings}. -% \advisespace -% This could be a compatibility problem. Make a bug report as described -% in section \lstref{uTroubleshooting}. -% \end{advise} -% The extended characters don't cover Arabic, Chinese, Hebrew, Japanese, and so -% on. Read section \ref{uNationalCharacters} for details on work-arounds. -% -% -% \subsection{Line numbers}\label{uLineNumbers} -% -% You already know the keys \ikeyname{numbers}, \ikeyname{numberstyle}, -% \ikeyname{stepnumber}, and \ikeyname{numbersep} from section -% \ref{gSeduceToUse}. Here now we deal with continued listings. -% You have two options to get consistent line numbering across listings. -% -% \begin{lstsample}[firstnumber]{\lstset{numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} -% \begin{lstlisting}[firstnumber=100] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% \end{lstlisting} -% And we continue the listing: -% \begin{lstlisting}[firstnumber=last] -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% In the example, \ikeyname{firstnumber} is initially set to 100; some lines -% later the value is \texttt{last}, which continues the numbering of the last -% listing. Note that the empty line at the end of the first part is not printed -% here, but it counts for line numbering. You should also notice that you can -% write |\lstset{firstnumber=last}| once and get consecutively numbered code -% lines---except you specify something different for a particular listing. -% -% On the other hand you can use |firstnumber=auto| and name your listings. -% Listings with identical names (case sensitive!) share a line counter. -% \begin{lstsample}[name]{\lstset{numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} -% \begin{lstlisting}[name=Test] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% -% \end{lstlisting} -% And we continue the listing: -% \begin{lstlisting}[name=Test] -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% The next |Test| listing goes on with line number {\makeatletter\lstno@Test}, -% no matter whether there are other listings in between. -% \begin{advise} -% \item Okay. And how can I get decreasing line numbers? -% \advisespace -% Sorry, what? -% \advisespace -% Decreasing line numbers as on page \pageref{rDecreasingLabels}. -% \advisespace -% May I suggest to demonstrate your individuality by other means? -% If you differ, you should try a negative `\ikeyname{stepnumber}' -% (together with `\ikeyname{firstnumber}'). -% \end{advise} -% -% Read section \ref{uHowTos} on how to reference line numbers. -% -% -% \subsection{Layout elements} -% -% It's always a good idea to structure the layout by vertical space, -% horizontal lines, or different type sizes and typefaces. The best to stress -% whole listings are---not all at once---colours, frames, vertical space, and -% captions. The latter are also good to refer to listings, of course. -% -% \paragraph{Vertical space} -% The keys {\rstyle\ikeyname{aboveskip}} and {\rstyle\ikeyname{belowskip}} -% control the vertical space above and below displayed listings. Both keys get -% a dimension or skip as value and are initialized to |\medskipamount|. -% -% \paragraph{Frames} -% The key \ikeyname{frame} takes the verbose values \keyvalue{none}, -% \keyvalue{leftline}, \keyvalue{topline}, \keyvalue{bottomline}, -% \keyvalue{lines} (top and bottom), \keyvalue{single} for single frames, or -% \keyvalue{shadowbox}. -% \begin{lstsample}[frame]{}{} -% \begin{lstlisting}[frame=single] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item The rules aren't aligned. -% \advisespace -% This could be a bug of this package or a problem with your -% \texttt{.dvi} driver. \emph{Before} sending a bug report to the package -% author, modify the parameters described in section \ref{rFrames} -% heavily. And do this step by step! -% For example, begin with `|framerule=10mm|'. If the rules are -% misaligned by the same (small) amount as before, the problem does not -% come from the rule width. So continue with the next parameter. -% \end{advise} -% Alternatively you can control the rules at the \texttt{t}op, \texttt{r}ight, -% \texttt{b}ottom, and \texttt{l}eft directly by using the four initial letters -% for single rules and their upper case versions for double rules. -% \begin{lstsample}[frame]{}{} -% \begin{lstlisting}[frame=trBL] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% Note that a corner is drawn if and only if both adjacent rules are requested. -% You might think that the lines should be drawn up to the edge, but what's -% about round corners? The key \ikeyname{frameround} must get exactly four -% characters as value. The first character is attached to the upper right -% corner and it continues clockwise. `\texttt{t}' as character makes the -% corresponding corner round. -% \begin{lstsample}[frameround]{}{} -% \lstset{frameround=fttt} -% \begin{lstlisting}[frame=trBL] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% Note that \ikeyname{frameround} has been used together with |\lstset| and thus -% the value affects all following listings in the same group or environment. -% Since the listing is inside a \texttt{minipage} here, this is no problem. -% \begin{advise} -% \item Dont' use frames all the time, in particular not with short listings. -% This would emphasize nothing. Use frames for $10\%$ or even less of -% your listings, for your most important ones. -% \item If you use frames on floating listings, do you really want frames? -% \advisespace -% No, I want to separate floats from text. -% \advisespace -% Then it is better to redefine \LaTeX's `|\topfigrule|' and -% `|\botfigrule|'. For example, you could write -% `|\renewcommand*\topfigrule{\hrule\kern-0.4pt\relax}|' and make the -% same definition for |\botfigrule|. -% \end{advise} -% -% \paragraph{Captions} -% Now we come to \ikeyname{caption} and \ikeyname{label}. You might guess that -% they can be used in the same manner as \LaTeX's |\caption| and |\label| -% commands: -% \begin{lstsample}[caption,label]{\lstset{xleftmargin=.05\linewidth}}{} -% \begin{lstlisting}[caption={Useless code},label=useless] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% Afterwards you could refer to the listing via |\ref{useless}|. By default -% such a listing gets an entry in the list of listings, which can be printed -% with the command {\rstyle\icmdname\lstlistoflistings}. The key -% {\rstyle\ikeyname{nolol}} suppresses an entry for both the environment or -% the input command. Moreover, you can specify a short caption for the list -% of listings: -% \keyname{caption}|={|\oarg{short}\meta{long}|}|. -% Note that the whole value is enclosed in braces since an optional value is -% used in an optional argument. -% -% If you don't want the label \texttt{\lstlistingname} plus number, you should -% use \ikeyname{title}: -% \begin{lstsample}[title]{\lstset{xleftmargin=.05\linewidth}}{} -% \begin{lstlisting}[title={`Caption' without label}] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item Something goes wrong with `\keyname{title}' in my document: in front of -% the title is a delimiter. -% \advisespace -% The result depends on the document class; some are not compatible. -% Contact the package author for a work-around. -% \end{advise} -% -% \paragraph{Colours} -% One more element. You need the \packagename{color} package and can then -% request coloured background via -% \ikeyname{backgroundcolor}|=|\meta{color command}. -% \begin{advise} -% \item Great! I love colours. -% \advisespace -% Fine, yes, really. And I like to remind you of the warning about -% striking styles on page \pageref{wStrikingStyles}. -% \end{advise} -%\ifcolor -% \begin{lstxsample}[backgroundcolor] -% \lstset{backgroundcolor=\color{yellow}} -% \end{lstxsample} -%\else -% \begin{verbatim} -% color package not installed\end{verbatim} -%\fi -% \begin{lstsample}{}{} -% \begin{lstlisting}[frame=single, -% framerule=0pt] -% for i:=maxint to 0 do -% begin -% j:=square(root(i)); -% end; -% \end{lstlisting} -% \end{lstsample} -% The example also shows how to get coloured space around the whole listing: -% use a frame whose rules has no width. -% -% -% \subsection{Emphasize identifiers}\label{uEmphasizeIdentifiers} -% -% Recall the pretty-printing commands and environment. |\lstinline| prints -% code snippets, |\lstinputlisting| whole files, and \texttt{lstlisting} -% pieces of code which reside in the \LaTeX\ file. And what are these -% different `types' of source code good for? Well, it just happens that a -% sentence contains a code fragment. Whole files are typically included in or -% as an appendix. Nevertheless some books about programming also include such -% listings in normal text sections---to increase the number of pages. -% Nowadays source code should be shipped on disk or CD-ROM and only the main -% header or interface files should be typeset for reference. So, please, don't -% misuse the \packagename{listings} package. But let's get back to the topic. -% -% Obviously `\texttt{lstlisting} source code' isn't used to make an executable -% program from. Such source code has some kind of educational purpose or even -% didactic. -% \begin{advise} -% \item What's the difference between educational and didactic? -% \advisespace -% Something educational can be good or bad, true or false. -% Didactic is true by definition.^^A :-) -% \end{advise} -% Usually \emph{keywords} are highlighted when the package typesets a piece of -% source code. This isn't necessary for readers knowing the programming -% language well. The main matter is the presentation of interface, library or -% other functions or variables. If this is your concern, here come the right -% keys. Let's say, you want to emphasize the functions |square| and |root|, -% for example, by underlining them. Then you could do it like this: -% \begin{lstxsample}[emph,emphstyle] -% \lstset{emph={square,root},emphstyle=\underbar} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% j:=square(root(i)); -% end; -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item Note that the list of identifiers |{square,root}| is enclosed in -% braces. Otherwise the \packagename{keyval} package would complain -% about an undefined key \keyname{root} since the comma finishes the -% key=value pair. -% Note also that you \emph{must} put braces around the value if you -% use an optional argument of a key inside an optional argument of a -% pretty-printing command. Though it is not necessary, the following -% example uses these braces. They are typically forgotten when they -% become necessary, -% \end{advise} -% -% Both keys have an optional \meta{class number} argument for multiple -% identifier lists: -%\ifcolor -% \begin{lstxsample}[emph,emphstyle] -% \lstset{emph={square}, emphstyle=\color{red}, -% emph={[2]root,base},emphstyle={[2]\color{blue}}} -% \end{lstxsample} -%\else -% \begin{lstxsample}[emph,emphstyle] -% \lstset{emph={square}, emphstyle=\underbar, -% emph={[2]root,base},emphstyle={[2]\fbox}} -% \end{lstxsample} -%\fi -% \begin{lstsample}{}{} -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% j:=square(root(i)); -% end; -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item What is the maximal \meta{class number}? -% \advisespace -% $2^{31}-1=2\,147\,483\,647$. But \TeX's memory will exceed before you -% can define so many different classes. -% \end{advise} -% -% One final hint: Keep the lists of identifiers disjoint. Never use a keyword -% in an `emphasize' list or one name in two different lists. Even if your -% source code is highlighted as expected, there is no guarantee that it is -% still the case if you change the order of your listings or if you use the -% next release of this package. -% -% -%\iffalse -% \subsection{*Listing alignment}\label{uListingAlignment} -% -% The examples are typeset with centered \texttt{minipage}s. That's the reason -% why you can't see that line numbers are printed in the margin. Now we -% separate the minipage margin and the minipage by a vertical rule: -% \begin{lstsample}{\lstset{frame=l,framesep=0pt,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} -% Some text before -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% \end{lstsample} -% The listing is lined up with the normal text. The parameter \ikeyname{xleftmargin} -% moves the listing to the right (or left if the dimension is negative). -% \begin{lstsample}{\lstset{frame=l,framesep=0pt,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} -% Some text before -% \begin{lstlisting}[xleftmargin=15pt] -% for i:=maxint to 0 do -% begin -% { do nothing } -% end; -% \end{lstlisting} -% -% \begin{lstlisting}{ } -% Write('Insensitive'); -% WritE('keywords.'); -% \end{lstlisting} -% \end{lstsample} -% Note again that optional arguments change settings for single listings. -% -% If you use environments like \texttt{itemize} or \texttt{enumerate}, there -% is `natural' indention coming from these environments. By default the -% \packagename{listings} package respects this. But you might use -% |resetmargins=true| (or |false|) to make your own decision. You can use it -% together with |xleftmargin|, of course. -% \begin{advise} -% \item I get heavy overfull |\hbox|es from some listings. -% \advisespace -% This comes from long lines in your listings. You have some options -% to get rid of the overful |\hbox|es. Firstly I recommend to typeset -% listings in smaller fonts than the surrounding text, for example -% `|basicstyle=\small|'. Secondly you might want to use the flexible -% column format. Thirdly you can increase the line width or set it -% explicitly, refer section \ref{rMarginsAndLineShape}. -% If all this doesn't help, you might want to change -% `\ikeyname{basewidth}', but be careful! The two unknown items are -% explained in the next section. -% \end{advise} -% -% You might need to control the vertical position of listings with the -% \ikeyname{boxpos} key, for example, if you use them in \texttt{minipage} or -% \texttt{tabular} environments. Here `listings' means \texttt{lstlisting} or -% |\lstinputlisting|. As the following example shows, you can even place such -% listings inside paragraphs, but you must force the package to do this by -% enclosing the listing in |\hbox{| and |}|. -% \begin{advise} -% \item Is it good form to use the \TeX-primitive `|\hbox|' in a \LaTeX\ -% document? -% \advisespace -% No, it's not. But \LaTeX's `|\mbox|' does not work in this example: -% \end{advise} -% \begin{lstsample}{}{} -% Here are some multi-line listings inside a paragraph. -% The `boxpos' key controls their vertical alignment: -% \hbox{\begin{lstlisting}[boxpos=c] -% center -% center -% \end{lstlisting}} -% \hbox{\begin{lstlisting}[boxpos=b] -% bottom baseline -% bottom baseline -% \end{lstlisting}} -% \hbox{\begin{lstlisting}[boxpos=t] -% top baseline -% top baseline -% \end{lstlisting}} -% \end{lstsample} -%\fi -% -% -% \subsection{Indexing}\label{uIndexing} -% -% is just like emphasizing identifiers---I mean the usage: -% \begin{lstxsample}[index] -% \lstset{index={square},index={[2]root}} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% j:=square(root(i)); -% end; -% \end{lstlisting} -% \end{lstsample} -% Of course, you can't see anything here. You will have to look at the index. -% \begin{advise} -% \item Why the `\ikeyname{index}' key is able to work with multiple identifier -% lists? -% \advisespace -% This question is strongly related to the `{\rstyle\ikeyname{indexstyle}}' -% key. Someone might want to create multiple indexes or want to insert -% prefixes like `|constants|', `|functions|', `|keywords|', and so on. -% The `\ikeyname{indexstyle}' key works like the other style keys except -% that the last token \emph{must} take an argument, namely the -% (printable form of the) current identifier. -% -% You can define `|\newcommand\indexkeywords[1]{\index{keywords, #1}}|' -% and make similar definitions for constant or function names. Then -% `|indexstyle=[1]\indexkeywords|' might meet your purpose. This becomes -% easier if you want to create multiple indexes with the -% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/camel} -% {\packagename{index}} package. -% If you have defined appropriate new indexes, it is possible to write -% `|indexstyle=\index[keywords]|', for example. -% -% \item Let's say, I want to index all keywords. It would be annoying to -% type in all the keywords again, specifically if the used programming -% language changes frequently. -% \advisespace -% Just read ahead. -% \end{advise} -% The \ikeyname{index} key has in fact two optional arguments. The first is the -% well-known \meta{class number}, the second is a comma separated list of other -% keyword classes whose identifiers are indexed. The indexed identifiers then -% change automatically with the defined keywords---not automagically, it's not -% an illusion.^^A :-) -% -% Eventually you need to know the names of the keyword classes. It's usually -% the key name followed by a class number, for example, |emph2|, |emph3|, -% \ldots, |keywords2| or |index5|. But there is no number for the first order -% classes |keywords|, |emph|, |directives|, and so on. -% \begin{advise} -% \item `|index=[keywords]|' does not work. -% \advisespace -% The package can't guess which optional argument you mean. Hence you -% must specify both if you want to use the second one. You should try -% `|index=[1][keywords]|'. -% \end{advise} -% -% -% \subsection{Fixed and flexible columns}\label{uFixedAndFlexibleColumns} -% -% The first thing a reader notices---except different styles for keywords, -% etc.---is the column alignment. Arne John Glenstrup invented the flexible -% column format in 1997. Since then some efforts were made to develop this -% branch farther. Currently three column formats are provided: fixed, flexible, -% and full flexible. Take a close look at the following examples. -% \begin{center} -% \lstset{style={},language={}} -% \def\sample{\begin{lstlisting}^^J WOMEN\ \ are^^A -% ^^J \ \ \ \ \ \ \ MEN^^A -% ^^J WOMEN are^^A -% ^^J better MEN^^J \end{lstlisting}} -% \begin{tabular}{@{}c@{\qquad\quad}c@{\qquad\quad}c@{\qquad\quad}c@{}} -% {\rstyle\ikeyname{columns}}|=| & \texttt{fixed} & \texttt{flexible} & \texttt{fullflexible}\\ -% & (at {\makeatletter\lst@widthfixed}) -% & (at {\makeatletter\lst@widthflexible}) -% & (at {\makeatletter\lst@widthflexible})\\ -% \noalign{\medskip} -% \lstset{basicstyle=\ttfamily,basewidth=0.51em}\sample -% & \lstset{columns=fixed}\sample -% & \lstset{columns=flexible}\sample -% & \lstset{columns=fullflexible}\sample -% \end{tabular} -% \end{center} -% \begin{advise} -% \item Why are women better men? -% \advisespace -% Do you want to philosophize? Well, have I ever said that the -% statement ``women are better men'' is true? I can't even remember this -% about ``women are men'' \ldots ^^A ;-)) -% \end{advise} -% In the abstract one can say: The fixed column format ruins the spacing -% intended by the font designer, while the flexible formats ruin the column -% alignment (possibly) intended by the programmer. Common to all is that the -% input characters are translated into a sequence of basic output units like -% \begingroup \lstset{gobble=6,xleftmargin=\leftmargini} -% \makeatletter -%^^A Make \fbox around each output unit. -% \fboxsep=0pt -% \def\lst@alloverstyle#1{\fbox{\kern-\fboxrule\strut#1}\kern-\fboxrule} -% \begin{lstlisting}[basewidth=1em] -% if x=y then write('align') -% else print('align'); -% \end{lstlisting} -% Now, the fixed format puts $n$ characters into a box of width $n\times{} -% $`base width', where the base width is {\makeatletter\lst@widthfixed} in the -% example. The format shrinks and stretches the space between the characters -% to make them fit the box. As shown in the example, some character strings look -% \hbox to 2em{b\hss a\hss d} -% or -% \hbox to 2em{w\hss o\hss r\hss s\hss e}, -% but the output is vertically aligned. -% \endgroup -% -% If you don't need or like this, you should use a flexible format. All -% characters are typeset at their natural width. In particular, they never -% overlap. If a word requires more space than reserved, the rest of the line -% simply moves to the right. The difference between the two formats is that the -% full flexible format cares about nothing else and the normal flexible format -% tries to fix the column alignment if a character string needs less space -% than `reserved'. In the flexible example above, the two MENs are vertically -% aligned since some space has been inserted in the fourth line to fix the -% alignment. In the full flexible format, the two MENs are not aligned. -% -% Note that both flexible modes printed the two blanks in the first line as a -% single blank, but for different reasons: the normal flexible format fixes -% the column alignment and the full flexible format doesn't care about the -% second space. -% -% -% \section{Advanced techniques}\label{uAdvancedTechniques} -% -% -% \subsection{Style definitions} -% -% It is obvious that a pretty-printing tool like this requires some kind of -% language selection and definition. The first has already been described and -% the latter is convered by the next section. However, it is very convenient -% to have the same for printing styles: at a central place of your document -% they can be modified easily and the changes take effect on all listings. -% -% Similar to languages, -% {\rstyle\ikeyname{style}}|=|\meta{style name} -% activates a previously defined style. A definition is as easy: -% {\rstyle|\lstdefinestyle|}\marg{style name}\marg{key=value list}. -% Keys not used in such a definition are untouched by the corresponding style -% selection, of course. For example, you could write -% \begin{verbatim} -% \lstdefinestyle{numbers} -% {numbers=left, stepnumber=1, numberstyle=\tiny, numbersep=10pt} -% \lstdefinestyle{nonumbers} -% {numbers=none}\end{verbatim} -% and switch from listings with line numbers to listings without ones and vice -% versa simply by |style=nonumbers| and |style=numbers|, respectively. -% \begin{advise} -% \item You could even write -% `|\lstdefinestyle{C++}{language=C++,style=numbers}|'. -% Style and language names are independent of each other and so might -% coincide. Moreover it is possible to activate other styles. -% -% \item It's easy to crash the package using styles. Write -% '|\lstdefinestyle{crash}{style=crash}|' and '|\lstset{style=crash}|'. -% \TeX's capacity will exceed, sorry [parameter stack size]. Only bad -% boys use such recursive calls, but only good girls use this package. -% Thus the problem is of minor interest.^^A :-) -% \end{advise} -% -% -% \subsection{Language definitions}\label{uLanguageDefinitions} -% -% This is like style definitions except for an optional dialect name and an -% optional base language---and, of course, a different command name and -% specialized keys. In the simple case it's -% {\rstyle|\lstdefinelanguage|}\marg{language name}\marg{key=value list}. -% For many programming languages it is sufficient to specify keywords and -% standard function names, comments, and strings. Let's look at an example. -% \begin{lstxsample}[morekeywords,sensitive,morecomment,morestring] -% \lstdefinelanguage{rock} -% {morekeywords={one,two,three,four,five,six,seven,eight, -% nine,ten,eleven,twelve,o,clock,rock,around,the,tonight}, -% sensitive=false, -% morecomment=[l]{//}, -% morecomment=[s]{/*}{*/}, -% morestring=[b]", -% } -% \end{lstxsample} -% \begingroup \csname lst@EndWriteFile\endcsname -% \bigbreak -% -% \noindent -% There isn't much to say about keywords. They are defined like identifiers -% you want to emphasize. Additionally you need to specify whether they are -% case sensitive or not. And yes: you could insert |[2]| in front of the -% keyword \texttt{one} to define the keywords as `second order' and print them -% in |keywordstyle={[2]...}|. -% \begin{advise} -% \item I get a `\texttt{Missing = inserted for }|\ifnum|' error when I select -% my language. -% \advisespace -% Did you forget the comma after `|keywords={...}|'? And if you encounter -% unexpected characters after selecting a language (or style), you have -% probably forgotten a different comma or you have given to many -% arguments to a key, for example, |morecomment=[l]{--}{!}|. -% \end{advise} -% -% So let's turn to comments and strings. Each value starts with a -% \emph{mandatory} \oarg{type} argument followed by a changing number of -% opening and closing delimiters. Note that each delimiter (pair) requires a -% key=value on its own, even if types are equal. Hence, you'll need to insert -% \texttt{morestring=[b]'} if single quotes open and close string or character -% literals in the same way as double quotes do in the example. -% -% Eventually you need to know the types and their numbers of delimiters. The -% reference guide contains full lists, here we discuss only the most common. -% For strings these are {\rstyle\texttt{b}} and {\rstyle\texttt{d}} with one -% delimiter each. This delimiter opens and closes the string and inside a -% string it is either escaped by a \texttt backslash or it is \texttt doubled. -% The comment type {\rstyle\texttt{l}} requires exactly one delimiter, which -% starts a comment on any column. This comment goes up to the end of line. -% The other two most common comment types are {\rstyle\texttt{s}} and -% {\rstyle\texttt{n}} with two delimiters each. The first delimiter opens a -% comment which is terminated by the second delimiter. In contrast to the -% \texttt s-type, \texttt n-type comments can be nested. -% \begin{lstxsample}[b,d,l,s,n] -% \lstset{morecomment=[l]{//}, -% morecomment=[s]{/*}{*/}, -% morecomment=[n]{(*}{*)}, -% morestring=[b]", -% morestring=[d]'} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% "str\"ing " not a string -% 'str''ing ' not a string -% // comment line -% /* comment/**/ not a comment -% (* nested (**) still comment -% comment *) not a comment -% \end{lstlisting} -% \end{lstsample} -% \begin{advise} -% \item Is it \emph{that} easy? -% \advisespace -% Almost. There are some troubles you can run into. For example, if -% `\texttt{-*}' starts a comment line and `\texttt{-*-}' a string -% (unlikely but possible), then you must define the shorter delimiter -% first. -% Another problem: by default some characters are not allowed inside -% keywords, for example `\texttt{-}', `\texttt{:}', `\texttt{.}', and -% so on. The reference guide covers this problem by introducing some -% more keys, which let you adjust the standard character table -% appropriately. But note that white space characters are prohibited -% inside keywords. -% \end{advise} -% Finally remember that this section is only an introduction to language -% definitions. There are more keys and possibilities. -% -% -% \subsection{Delimiters}\label{uDelimiters} -% -% You already know two special delimiter classes: comments and strings. -% However, their full syntax hasn't been described so far. For example, -% \ikeyname{commentstyle} applies to all comments---except you specify -% something different. The \emph{optional} \oarg{style} argument follows the -% \emph{mandatory} \oarg{type} argument. -%\ifcolor -% \begin{lstxsample} -% \lstset{morecomment=[l][keywordstyle]{//}, -% morecomment=[s][\color{white}]{/*}{*/}} -% \end{lstxsample} -%\else -% \begin{lstxsample} -% \lstset{morecomment=[l][keywordstyle]{//}, -% morecomment=[s][\underbar]{/*}{*/}} -% \end{lstxsample} -%\fi -% \begin{lstsample}{}{} -% \begin{lstlisting} -% // bold comment line -% a single /* comment */ -% \end{lstlisting} -% \end{lstsample} -% As you can see, you have the choice between specifying the style explicitly -% by \LaTeX\ commands or implicitly by other style keys. But, you're right, -% some implicitly defined styles have no seperate keys, for example the second -% order keyword style. Here---and never with the number 1---you just append -% the order to the base key: \texttt{keywordstyle2}. -% -% You ask for an application? Here you are: one can define different printing -% styles for `subtypes' of a comment, for example -%\ifcolor -% \begin{lstxsample} -% \lstset{morecomment=[s][\color{blue}]{/*+}{*/}, -% morecomment=[s][\color{red}]{/*-}{*/}} -% \end{lstxsample} -%\else -% \begin{lstxsample} -% \lstset{morecomment=[s][\upshape]{/*+}{*/}, -% morecomment=[s][\bfseries]{/*-}{*/}} -% \end{lstxsample} -%\fi -% \begin{lstsample}{\lstset{morecomment=[s]{/*}{*/}}}{} -% \begin{lstlisting} -% /* normal comment */ -% /*+ keep cool */ -% /*- danger! */ -% \end{lstlisting} -% \end{lstsample} -% Here, the comment style is not applied to the second and third line. -% \begin{advise} -% \item Please remember that both `extra' comments must be defined \emph{after} -% the normal comment, since the delimiter `\texttt{/*}' is a substring of -% `\texttt{/*+}' and `\texttt{/*-}'. -% -% \item I have another question. Is `\texttt{language=}\meta{different -% language}' the only way to remove such additional delimiters? -% \advisespace -% Call {\rstyle\ikeyname{deletecomment}} and/or -% {\rstyle\ikeyname{deletestring}} with the same arguments to remove -% the delimiters (but you don't need to provide the optional style -% argument). -% \end{advise} -% Eventually, you might want to use the prefix \texttt{i} on any comment type. -% Then the comment is not only invisible, it is completely discarded from the -% output! -% \begin{lstxsample}[is] -% \lstset{morecomment=[is]{/*}{*/}} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% begin /* comment */ end -% begin/* comment */end -% \end{lstlisting} -% \end{lstsample} -% -% Okay, and now for the real challenges. More general delimiters can be defined -% by the key {\rstyle\ikeyname{moredelim}}. Legal types are {\rstyle\texttt{l}} -% and {\rstyle\texttt{s}}. These types can be preceded by an \texttt{i}, but -% this time \emph{only the delimiters} are discarded from the output. This way -% you can select styles by markers. -% \begin{lstxsample} -% \lstset{moredelim=[is][\ttfamily]{|}{|}} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% roman |typewriter| -% \end{lstlisting} -% \end{lstsample} -% You can even let the package detect keywords, comments, strings, and other -% delimiters inside the contents. -% \begin{lstxsample} -% \lstset{moredelim=*[s][\itshape]{/*}{*/}} -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% /* begin -% (* comment *) -% ' string ' */ -% \end{lstlisting} -% \end{lstsample} -% Moreover, you can force the styles being applied cumulative. -% \begin{lstxsample} -% \lstset{moredelim=**[is][\ttfamily]{|}{|}, % cumulative -% moredelim=*[s][\itshape]{/*}{*/}} % not so -% \end{lstxsample} -% \begin{lstsample}{}{} -% \begin{lstlisting} -% /* begin -% ' string ' -% |typewriter| */ -% -% | begin -% ' string ' -% /*typewriter*/ | -% \end{lstlisting} -% \end{lstsample} -% Look carefully at the output and note the differences. The second -% \texttt{begin} is not printed in bold typewriter type since standard -% \LaTeX\ has no such font. -% -% This suffices for an introduction. Now go and find some more applications. -% -% -% \subsection{Closing and credits}\label{uClosingAndCredits} -% -% You've seen a lot of keys but you are far away from knowing all of them. -% The next step is the real use of the \packagename{listings} package. -% Please take the following advices.

\part{Reference guide} -% -% -% \section{Main reference}\label{rMainReference} -% -% Your first training is completed. Now that you've left the User's guide, the -% friend telling you what to do has gone. Get more practice and become a -% journeyman!^^A :-) -% \begin{advise} -% \item Actually, the friend hasn't gone. There are still some advices, but -% only from time to time. -% \end{advise} -% -% -% \subsection{How to read the reference} -% -% Commands, keys and environments are presented as follows. -% \begin{syntax} -% \item[1.0,default,hints] \texttt{command}, \texttt{environment} or -% \keyname{key} with \meta{parameters} -% -% This field contains the explanation; here we describe the other fields. -% -% If present, the label in the left margin provides extra information: -% `\textit{addon}' indicates additionally introduced functionality, -% `\textit{changed}' a modified key, `\textit{data}' a command just -% containing data (which is therefore adjustable via |\renewcommand|), -% and so on. Some keys and functionality are `\emph{bug}'-marked or -% with a \dag-sign. These features might change in future or could be -% removed, so use them with care. -% -% If there is verbatim text touching the right margin, it is the -% predefined value. Note that some keys default to this value every -% listing, namely the keys which can be used on individual listings only. -% -% The label in the right margin is the current version number and marks -% newly introduced features. -% \end{syntax} -% Regarding the parameters, please keep in mind the following: -% \begin{enumerate} -% \item A list always means a comma separated list. You must put braces around -% such a list. Otherwise you'll get in trouble with the -% \packagename{keyval} package; it complains about an undefined key. -% \item You must put parameter braces around the whole value of a key if you -% use an \oarg{optional argument} of a key inside an optional -% \oarg{key=value list}: -% |\begin{lstlisting}[caption=|{\rstyle|{|}|[one]two|{\rstyle|}|}|]|. -% \item Brackets `|[ ]|' usually enclose optional arguments and must be typed -% in verbatim. Normal brackets `[ ]' always indicate an optional argument -% and must not be typed in. Thus |[*]| must be typed in exactly as is, -% but [|*|] just gets |*| if you use this argument. -% \item A vertical rule indicates an alternative, e.g.~^^A -% \meta{\alternative{true,false}} allows either \texttt{true} or -% \texttt{false} as arguments. -% \item If you want to enter one of the special characters |{}#%\|, this -% character must be escaped with a backslash. This means that you must -% write |\}| for the single character `right brace'---but of course not -% for the closing paramater character. -% \end{enumerate} -% -% -% \subsection{Typesetting listings}\label{rTypesettingListings} -% -% \begin{syntax} -% \item[0.19] \rcmdname\lstset\marg{key=value list} -% -% sets the values of the specified keys, see also section -% \ref{uTheKey=ValueInterface}. -% The parameters keep their values up to the end of the current group. -% In opposition, all optional \meta{key=value list}s below modify the -% parameters for single listings only. -% -% \item[0.18] \rcmdname\lstinline\oarg{key=value list}\meta{character}\meta{source code}\meta{same character} -% -% works like |\verb| but respects the active language and style. These -% listings use flexible columns except requested differently in the -% optional argument. You can write `|\lstinline!var i:integer;!|' and -% get `\lstinline!var i:integer;!'. -% -% Since the command first looks ahead for an optional argument, you must -% provide at least an empty one if you want to use |[| as -% \meta{character}. -% -% \dag\ An experimental implementation has been done to support the -% syntax |\lstinline|\oarg{key=value list}\marg{source code}. Try it if -% you want and report success and failure. A known limitation is that -% inside another argument the last source code token must not be an -% explicit space token---and, of course, using a listing inside another -% argument is itself experimental, see section \ref{rListingsInsideArguments}. -% -% \item[0.15] |\begin{|\texttt{\rstyle lstlisting}|}|\oarg{key=value list} -% -% \leavevmode\hspace*{-\leftmargini}|\end{|\texttt{\rstyle lstlisting}|}| -% -% typesets the code in between as a displayed listing. -% -% In contrast to the environment of the \packagename{verbatim} package, -% \LaTeX\ code on the same line and after the end of environment is -% typeset respectively executed. -% -% \item[0.1] \rcmdname\lstinputlisting\oarg{key=value list}\marg{file name} -% -% typesets the stand alone source code file as a displayed listing. -% \end{syntax} -% -% -% \subsection{Space and placement} -% -% \begin{syntax} -% \item[0.20,floatplacement] \rkeyname{float}|=|[|*|]\meta{subset of \textup{\texttt{tbph}}}\syntaxor\rkeyname{float} -% -% makes sense on individual displayed listings only and lets them float. -% The argument controls where \LaTeX\ is \emph{allowed} to put the float: -% at the top or bottom of the current/next page, on a separate page, or -% here where the listing is. -% -% The optional star can be used to get a double-column float in a -% two-column document. -% -% \item[0.21,tbp] \rkeyname{floatplacement}|=|\meta{place specifiers} -% -% is used as place specifier if \keyname{float} is used without value. -% -% \item[0.21,\medskipamount] \rkeyname{aboveskip}|=|\meta{dimension} -% \item[0.21,\medskipamount] \rkeyname{belowskip}|=|\meta{dimension} -% -% define the space above and below displayed listings. -% -% \item[0.17,0pt,\dag] \rkeyname{lineskip}|=|\meta{dimension} -% -% specifies additional space between lines in listings. -% -% \item[0.18,c,\dag] \rkeyname{boxpos}|=|\meta{\alternative{b,c,t}} -% -% Sometimes the \packagename{listings} package puts a |\hbox| around a -% listing---or it couldn't be printed or even processed correctly. -% The key determines the vertical alignment to the surrounding material: -% bottom baseline, centered or top baseline. -% \end{syntax} -% -% -% \subsection{The printed range} -% -% \begin{syntax} -% \item[0.12,true] \rkeyname{print}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{print} -% -% controls whether an individual displayed listing is typeset. Even if -% set false, the respective caption is printed and the label is defined. -% -% Note: If the package is loaded without the \texttt{draft} option, you -% can use this key together with |\lstset|. In the other case the key -% can only be used to typeset particular listings despite of the -% \texttt{draft} option. -% -% \item[0.1,1] \rkeyname{firstline}|=|\meta{number} -% \item[0.1,9999999] \rkeyname{lastline}|=|\meta{number} -% -% can be used on individual listings only.

Since \TeX\ reads the argument before -% the `\lst-macro' is executed, this package can't do anything to preserve the -% input: spaces shrink to one space, the tabulator and the end of line are -% converted to spaces, \TeX's comment character is not printable, and so on. -% Hence, \emph{you} must work a bit more. You have to put a backslash in front -% of each of the following four characters: |\{}%|. Moreover you must protect -% spaces in the same manner if: (i) there are two or more spaces following each -% other or (ii) the space is the first character in the line. -% That's not enough: Each line must be terminated with a `line feed' |^^J|. -% And you can't escape to \LaTeX\ inside such listings! -% -% The easiest examples are with |\lstinline| since we need no line feed. -% \begin{verbatim} -%\footnote{\lstinline{var i:integer;} and -% \lstinline!protected\ \ spaces! and -% \fbox{\lstinline!\\\{\}\%!}}\end{verbatim} -% yields\lstset{language=Pascal}\footnote{\lstinline{var i:integer;} and -% \lstinline!protected\ \ spaces! and -% \fbox{\lstinline!\\\{\}\%!}} -% if the current language is Pascal.

In general that's a -% dream so far. The problem is that programming languages use various syntaxes -% for function and procedure declaration or definition. A general interface is -% completely out of the scope of this package---that's the work of a compiler -% and not of a pretty-printing tool. However, it is possible for particular -% languages: in Pascal each function or procedure definition and variable -% declaration is preceded by a particular keyword. -% Note that you must request the following keys with \texttt{procnames} option: -% |\usepackage[procnames]{listings}|. -% \begin{syntax} -% \item[0.19,{{}},{\dag optional}] \rkeyname{procnamekeys}|=|\marg{keywords} -% \item[0.21,,\dag optional] \rkeyname{moreprocnamekeys}|=|\marg{keywords} -% \item[0.21,,\dag optional] \rkeyname{deleteprocnamekeys}|=|\marg{keywords} -% -% each specified keyword indicates a function or procedure definition. -% Any identifier following such a keyword appears in `procname' style. -% For Pascal you might use\vspace{-.5\baselineskip} -% \begin{verbatim} -% procnamekeys={program,procedure,function}\end{verbatim} -% -% \item[0.19,keywordstyle,\dag optional] \rkeyname{procnamestyle}|=|\meta{style} -% -% defines the style in which procedure and function names appear. -% -% \item[0.19,false,\dag optional] \rkeyname{indexprocnames}|=|\meta{\alternative{true,false}} -% -% If activated, procedure and function names are also indexed. -% \end{syntax} -% \begin{TODO} -% The \aspectname{procnames} aspect is unsatisfactory (since unchanged for more -% than four years). It marks and indexes the function definitions so far, but -% it would be possible to mark also the following function calls, for example. -% A key could control whether function names are added to a special keyword -% class, which then appears in `procname' style. But should these names be -% added globally? There are good reasons for both. Of course, we would also -% need a key to reset the name list. -% \end{TODO} -% -% -% \subsection{\dag\ Hyper references}\label{rHyperReferences} -% -% This very small aspect must be requested via \texttt{hyper} option since it -% is experimental. One perspective for the future is to combine this aspect -% with \aspectname{procnames}. Then it should be possible to click on a -% function name and jump to its definition, for example. -% \begin{syntax} -% \item[0.21,,{\dag optional}] \rkeyname{hyperref}|=|\marg{identifiers} -% \item[0.21,,{\dag optional}] \rkeyname{morehyperref}|=|\marg{identifiers} -% \item[0.21,,{\dag optional}] \rkeyname{deletehyperref}|=|\marg{identifiers} -% -% Hyper references the specified identifiers (via \packagename{hyperref} -% package).

For example, |{-}| must be used -% before |{--}| and this before |{-->}|. -% \end{syntax} -% In the example above I've used -% \begin{verbatim} -% literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1\end{verbatim} -% \begin{TODO} -% Of course, it's good to have keys for adding and removing single -% \meta{replacement item}s. Maybe the key(s) should work in the same fashion -% as the string and comment definitions, i.e.~one item per key=value. -% This way it would be easier to provide better auto-detection in case of a -% subsequence. -% \end{TODO} -% -% -% \subsection{\textsf{LGrind} definitions}\label{rLGrindDefinitions} -% -% Yes, it's a nasty idea to steal language definitions from other programs. -% Nevertheless, it's possible for the \packagename{LGrind} definition -% file---at least partially.

First of -% all, there are no general rules on how source code should be formatted. So -% `format definitions' must be flexible. This flexibility requires a complex -% interface, a powerful `format definition' parser, and lots of code lines -% behind the scenes. Currently, format definitions aren't flexible enough -% (possibly not the definitions but the results). A single `format item' has -% the form -% \begin{itemize}\item[] -% \meta{input chars}|=|\oarg{exceptional chars}\meta{pre}\oarg{\texttt{\string\string}}\meta{post} -% \end{itemize} -% Whenever \meta{input chars} aren't followed by one of the \meta{exceptional -% chars}, formatting is done according to the rest of the value. If |\string| -% isn't specified, the input characters aren't printed (except it's an -% identifier or keyword). Otherwise \meta{pre} is `executed' before printing -% the original character string and \meta{post} afterwards. These two are -% `subsets' of -% \begin{itemize} -% \item |\newline| ---ensuring a new line; -% \item |\space| ---ensuring a whitespace; -% \item |\indent| ---increasing indention; -% \item |\noindent| ---descreasing indention. -% \end{itemize} -% Now we can give an example.\lstaspectindex{\lstdefineformat}{}\lstaspectindex{format}{} -% \begin{lstxsample} -% \lstdefineformat{C}{% -% \{=\newline\string\newline\indent,% -% \}=\newline\noindent\string\newline,% -% ;=[\ ]\string\space} -% \end{lstxsample} -% \begin{lstsample}{\lstset{language={}}}{} -% \begin{lstlisting}[format=C] -% for (int i=0;i<10; i++){/* wait */}; -% \end{lstlisting} -% \end{lstsample} -% Not good. But there is a (too?) simple work-around: -% \begin{lstxsample} -% \lstdefineformat{C}{% -% \{=\newline\string\newline\indent,% -% \}=[;]\newline\noindent\string\newline,% -% \};=\newline\noindent\string\newline,% -% ;=[\ ]\string\space} -% \end{lstxsample} -% \begin{lstsample}{\lstset{language={}}}{} -% \begin{lstlisting}[format=C] -% for (int i=0;i<10; i++){/* wait */}; -% \end{lstlisting} -% \end{lstsample} -% Sometimes the problem is just to find a suitable format definition. -% Further formatting is complicated. -% Here are only three examples with increasing level of difficulty. -% \begin{enumerate} -% \item Insert horizontal space to separate function/procedure name and -% following parenthesis or to separate arguments of a function, -% e.g.~add the space after a comma (if inside function call). -% \item Smart breaking of long lines. Consider long `and/or' expressions. -% Formatting should follow the logical structure! -% \item Context sensitive formatting rules. It can be annoying if empty -% or small blocks take three or more lines in the output---think of -% scrolling down all the time. So it would be nice if the block -% formatting was context sensitive. -% \end{enumerate} -% Note that this is a very first and clumsy attempt to provide automatic -% formatting---clumsy since the problem isn't trivial. Any ideas are welcome. -% Implementations also. Eventually you should know that you must request format -% definitions at package loading, e.g.~via |\usepackage[formats]{listings}|. -% -% \subsection{Arbitrary linerange markers}\label{rArbitraryLinerangeMarkers} -% -% Instead of using \keyname{linerange} with line numbers, one can use text -% markers.

First you should -% consult the reference guide whether the problem is already known. If not, -% create a \emph{minimal} file which reproduces the problem. Follow these -% instructions: -% \begin{enumerate} -% \item Start from the minimal file in section \ref{uAMinimalFile}. -% \item Add the \LaTeX\ code which causes the problem, but keep it short. -% In particular, keep the number of additional packages small. -% \item Remove some code from the file (and the according packages) until the -% problem disappears.

Send a bug report to the address on the -% first page of this documentation and include the minimal file together -% with the created \texttt{.log}-file. If you use a very special package -% (i.e.~not on CTAN), also include the package if its software license -% allows it. -% \end{enumerate} -% -% -% \section{How tos}\label{uHowTos} -% -% -% \subsubsection*{How to reference line numbers} -% You want to put |\label{|\meta{whatever}|}| into a \LaTeX\ escape which is -% inside a comment whose delimiters aren't printed? The compiler won't see the -% \LaTeX\ code since inside a comment, and the \packagename{listings} package -% won't print anything since the delimiters are dropped and |\label| doesn't -% produce any printable output. Well, your wish is granted. -% -% In Pascal, for example, you could make the package recognize the `special' -% comment delimiters |(*@| and |@*)| as begin-escape and end-escape sequences. -% Then you can use this special comment for |\label|s and other things. -% \begin{lstsample}{\lstset{numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} -% \lstset{escapeinside={(*@}{@*)}} -% -% \begin{lstlisting} -% for i:=maxint to 0 do -% begin -% { comment }(*@\label{comment}@*) -% end; -% \end{lstlisting} -% Line \ref{comment} shows a comment. -% \end{lstsample} -% \begin{advise} -% \item Can I use `|(*@|' and `|*)|' instead? -% \advisespace -% Yes. -% \item Can I use `|(*|' and `|*)|' instead? -% \advisespace -% Sure. If you want this. -% \item Can I use `|{@|' and `|@}|' instead? -% \advisespace -% No, never! The second delimiter is not allowed. The character `|@|' is -% defined to check whether the escape is over. But reading the lonely -% `end-argument' brace, \TeX\ encounters the error `\texttt{Argument of @ -% has an extra \char125}'. Sorry. -% \item Can I use `|{|' and `|}|' instead? -% \advisespace -% No. Again the second delimiter is not allowed. Here now \TeX\ would -% give you a `\texttt{Runaway argument}' error. Since `|}|' is defined to -% check whether the escape is over, it won't work as `end-argument' brace. -% \item And how can I use a comment line? -% \advisespace -% For example, write `|escapeinside={//*}{\^^M}|'. Here |\^^M| represents -% the end of line character. -% \end{advise} -% -% -% \subsubsection*{How to gobble characters} -% To make your \LaTeX\ code more readable, you might want to indent your -% \texttt{lstlisting} listings. This indention must be removed for -% pretty-printing. If you indent each code line by three characters, you can -% remove them via |gobble=3|: -% \begin{lstsample}{}{\lstset{showspaces}} -% \begin{lstlisting}[gobble=3] -% 1 for i:=maxint to 0 do -% 2 begin -% 3 { do nothing } -% 123end; -% -% Write('Case insensitive '); -% WritE('Pascal keywords.'); -% \end{lstlisting} -% \end{lstsample} -% Note that empty lines as well as the beginning and the end of the environment -% need not to respect the indention. But never indent the end by more than -% `\ikeyname{gobble}' characters. Moreover note that tabulators expand to -% |tabsize| spaces before we gobble. -% \begin{advise} -% \item Could I use `\ikeyname{gobble}' together with `|\lstinputlisting|'? -% \advisespace -% Yes, but it has no effect. -% -% \item Note that `\ikeyname{gobble}' can also be set via `|\lstset|'. -% \end{advise} -% -% -% \subsubsection*{How to include graphics} -% \lsthelper{Herbert~Weinhandl}{1999/09/06}{listings + eps} found a very easy -% way to include graphics in listings. Thanks for contributing this idea---an -% idea I never have had. -% -% Some programming languages allow the dollar sign to be part of an identifier. -% But except for intermediate function names or library functions, this -% character is most often unused. The \packagename{listings} package defines -% the \ikeyname{mathescape} key, which lets `|$|' escape to \TeX's math mode. -% This makes the dollar character an excellent candidate for our purpose here: -% use a package which can include a graphic, set \ikeyname{mathescape} true, -% and include the graphic between two dollar signs, which are inside a comment. -% -% The following example is originally from a header file I got from Herbert. -% For the presentation here I use the \texttt{lstlisting} environment and an -% excerpt from the header file. The |\includegraphics| command is from -% David Carlisle's \packagename{graphics} bundle. -% \begin{verbatim} -% \begin{lstlisting}[mathescape=true] -% /* -% $ \includegraphics[height=1cm]{defs-p1.eps} $ -% */ -% typedef struct { -% Atom_T *V_ptr; /* pointer to Vacancy in grid */ -% Atom_T *x_ptr; /* pointer to (A|B) Atom in grid */ -% } ABV_Pair_T; -% \end{lstlisting}\end{verbatim} -% The result looks pretty good. Unfortunately you can't see it. -% -% -% \subsubsection*{How to get closed frames on each page} -% The package supports closed frames only for listings which don't cross pages. -% If a listing is split on two pages, there is neither a bottom rule at the -% bottom of a page, nor a top rule on the following page. If you insist on -% these rules, you might want to use \texttt{framed.sty} by Donald Arseneau. -% Then you could write -% \begin{verbatim} -% \begin{framed} -% \begin{lstlisting} -% or \lstinputlisting{...} -% \end{lstlisting} -% \end{framed}\end{verbatim} -% The package also provides a \texttt{shaded} environment.

Here now one answer on how to use them -% in spite of that. -% \begin{advise} -% \item Please note that I personally don't regard the following as a good -% solution. Such a bold typewriter type is too heavy. It would be better -% to use a light version of \texttt{cmtt} as basic font and \texttt{cmtt} -% or a \emph{slightly} heavier type for keywords. -% -% \item Why don't you tell us how to use the better solution? -% \advisespace -% A light version of \texttt{cmtt} doesn't exist. If it's once available, -% you can do a similar job as described below. -% \end{advise} -% First of all, you'll need Metafont source files for bold typewriter, e.g.~ -% \texttt{cmbtt8.mf}, \texttt{cmbtt9.mf} and \texttt{cmbtt10.mf} from -% \href{ftp://ftp.dante.de/tex-archive/fonts/cm/mf-extra/bold} -% {CTAN/fonts/cm/mf-extra/bold}. -% Secondly you have to create \texttt{.tfm}-files, i.e.~run the Metafont -% program on these sources. This is possibly done automatically when you use -% the fonts in a document. Finally you must tell \LaTeX\ that you've installed -% bold typewriter fonts. Just use -% \begin{verbatim} -% \DeclareFontShape{OT1}{cmtt}{bx}{n} -% {<5><6><7><8>cmbtt8% -% <9>cmbtt9% -% <10><10.95>cmbtt10% -% <12><14.4><17.28><20.74><24.88>cmbtt10% -% }{}\end{verbatim} -% in the preamble of your document. If you use these fonts often, you might -% want to make a local copy of \texttt{ot1cmtt.fd} and replace the declaration -% there.

Both could -% be implemented in terms of \lst-aspects, which are simply collections of -% public keys and commands and internal hooks and definitions. The package -% defines a couple of aspects, in particular the kernel, the main engine. -% Other aspects drive this engine, and language and style definitions tell -% the aspects how to drive. The relations between car, driver and assistant -% driver are exactly reproduced---and I'll be your driving instructor. -% -% -% \subsection{Package loading}\label{dPackageLoading} -% -% Each option in |\usepackage[|\meta{options}|]{listings}| loads an aspect or -% \emph{prevents} the package from loading it if the aspect name is -% \emph{preceded by an exclamation mark}. This mechanism was designed to clear -% up the dependencies of different package parts and to debug the package. For -% this reason there is another option: -% \begin{syntax} -% \item[0.21,,option] \texttt{noaspects}\leavevmode -% -% deletes the list of aspects to load. Note that, for example, the -% option lists |0.21,!labels,noaspects| and |noaspects| are essentially -% the same: the kernel is loaded and no other aspect. -% \end{syntax} -% This is especially useful for aspect-testing since we can load exactly the -% required parts.

So use the -% following commands, |\gdef|, and commands described in later sections. -% \begin{syntax} -% \item[0.20] |\lst@UserCommand|\meta{macro}\meta{parameter text}\marg{replacement text} -% -% The macro is (mainly) equivalent to |\gdef|.

They tell you whether \TeX\ is in (restricted) -% horizontal or (internal) vertical or in (nondisplay) mathematical mode. For -% example, true |\ifhmode| and true |\ifinner| indicate restricted horizontal -% mode, which means that you are in a |\hbox|. The typical user doesn't care -% about such modes; \TeX/\LaTeX\ manages all this. But since you're reading the -% developer's guide, we discuss the analogue for the \packagename{listings} -% package now. It uses modes to distinguish comments from strings, `comment -% lines' from `single comments', and so on. -% -% The package is in `no mode' before reading the source code. In the phase of -% initialization it goes to `processing mode'. Afterwards the mode depends on -% the actual source code. For example, consider the line -% \begin{verbatim} -% "string" // comment\end{verbatim} -% and assume \texttt{language=C++}. Reading the string delimiter, the package -% enters `string mode' and processes the string. The matching closing delimiter -% leaves the mode, i.e.\ switches back to the general `processing mode'. Coming -% to the two slashes, the package detects a comment line; it therefore enters -% `comment line mode' and outputs the slashes. Usually this mode lasts to the -% end of line. -% -% But with \texttt{textcl=true} the \aspectname{escape} aspect immediately -% leaves `comment line mode', interrupts the current mode sequence, and enters -% `\TeX\ comment line mode'. At the end of line we reenter the previous mode -% sequence `no mode' $\to$ 'processing mode'. This escape to \LaTeX\ works -% since `no mode' implies that \TeX's characters and catcodes are present, -% whereas `processing mode' means that \packagename{listings}' characters and -% catcodes are active. -% -% \begin{table}[htbp] -% \caption{Internal modes}\label{dDefinedInternalModes} -% \def\lsttabspace{\hspace*{1em}\hfill} -% \begin{tabular}{@{}lp{0.56\linewidth}@{}} -% aspect\lsttabspace\meta{mode name} & Usage/We are processing \ldots\\ -% \noalign{\smallskip} -% kernel\lsttabspace |\lst@nomode| & -% If this mode is active, \TeX's `character table' is present; the other -% implication is not true.

But you will have difficulties if you want to make heavy -% alterations to the car. So let's take a closer look and come to the most -% difficult part: the engine. We'll have a look at the big picture and fill in -% the details step by step. For our purpose it's good to override \TeX's -% character table. First we define a standard character table which contains -% \begin{itemize} -% \item letters: characters identifiers are out of, -% \item digits: characters for identifiers or numerical constants, -% \item spaces: characters treated as blank spaces, -% \item tabulators: characters treated as tabulators, -% \item form feeds: characters treated as form feed characters, and -% \item others: all other characters. -% \end{itemize} -% This character table is altered depending on the current programming language. -% We may define string and comment delimiters or other special characters. -% Table \ref{rStdCharTable} on page \pageref{rStdCharTable} shows the standard -% character table. It can be modified with the keys \keyname{alsoletter}, -% \keyname{alsodigit}, and \keyname{alsoother}. -% -% How do these `classes' work together? Let's say that the current character -% string is `|tr|'. Then letter `|y|' simply appends the letter and we get -% `|try|'. The next nonletter (and nondigit) causes the output of the -% characters. Then we collect all coming nonletters until reaching a letter -% again. This causes the output of the nonletters, and so on. Internally each -% character becomes active in the sense of \TeX\ and is defined to do the right -% thing, e.g.~we say -% \begin{verbatim} -% \def A{\lst@ProcessLetter A}\end{verbatim} -% where the first `|A|' is active and the second has letter catcode 11. -% The macro |\lst@ProcessLetter| gets one token and treats it as a letter. -% The following macros exist, where the last three get no explicit argument. -% \begin{syntax} -% \item[0.18] |\lst@ProcessLetter| \meta{spec.\ token} -% \item[0.18] |\lst@ProcessDigit| \meta{spec.\ token} -% \item[0.18] |\lst@ProcessOther| \meta{spec.\ token} -% \item[0.18] |\lst@ProcessTabulator| -% \item[0.18] |\lst@ProcessSpace| -% \item[0.20] |\lst@ProcessFormFeed| -% \end{syntax} -% \meta{spec.\ token} is supposed to do two things. Usually it expands to -% a printable version of the character. But if |\lst@UM| is equivalent to -% |\@empty|, \meta{spec.\ token} must expand to a \emph{character token}. -% For example, the sharp usually expands to |\#|, which is defined via -% |\chardef| and is not a character token. But if |\lst@UM| is equivalent to -% |\@empty|, the sharp expands to the character `|#|' (catcode 12). Note: -% \emph{Changes to} |\lst@UM| \emph{must be locally.} However, there should -% be no need to do such basic things yourself. The \packagename{listings} -% package provides advanced macros which use that feature, -% e.g.~|\lst@InstallKeywords| in section \ref{dKeywordsAndWorkingIdentifiers}. -% -% \begin{syntax} -% \item[0.18] |\lst@Def|\marg{character code}\meta{parameter text}\marg{definition} -% \item[0.18] |\lst@Let|\marg{character code}\meta{token} -% -% defines the specified character respectively assigns \meta{token}. -% The catcode table if not affected. Be careful if your definition has -% parameters: it is not safe to read more than one character ahead. -% Moreover, the argument can be \emph{arbitrary}; somtimes it's the next -% source code character, sometimes it's some code of the -% \packagename{listings} package, e.g.~|\relax|, |\@empty|, |\else|, -% |\fi|, and so on. Therefore don't use \TeX's ord-operator |`| on such -% an argument, e.g.~don't write |\ifnum`#1=65| to test against `|A|'. -% -% |\lst@Def| and |\lst@Let| are relatively slow. The real definition of -% the standard character table differs from the following example, but it -% could begin with -% \begin{verbatim} -% \lst@Def{9}{\lst@ProcessTabulator} -% \lst@Def{32}{\lst@ProcessSpace} -% \lst@Def{48}{\lst@ProcessDigit 0} -% \lst@Def{65}{\lst@ProcessLetter A}\end{verbatim} -% -%\iffalse -% \item[0.20] |\lst@activecharstrue| -% \item[0.20] |\lst@activecharsfalse| -% -% control whether selecting the character table also makes all characters -% active (standard/extended). This is usually true and therefore default. -% Only the \packagename{fancyvrb} interface sets it locally false. -%\fi -% \end{syntax} -% That's enough for the moment. Section \ref{dUsefulInternalDefinitions} -% presents advanced definitions to manipulate the character table, in -% particular how to add new comment or string types. -% -% -% \subsection{On the output} -% -% The \packagename{listings} package uses some variables to keep the output -% data. Write access is not recommended. Let's start with the easy ones. -% \begin{syntax} -% \item[0.17,,data] |\lst@lastother| -% -% equals \meta{spec.\ token} version of the last processed -% nonidentifier-character. Since programming languages redefine the -% standard character table, we use the original \meta{spec.\ token}. -% For example, if a double quote was processed last, |\lst@lastother| -% is not equivalent to the macro which enters and leaves string mode. -% It's equivalent to |\lstum@"|, where |"| belongs to the control -% sequence. Remember that \meta{spec.\ token} expands either to a -% printable or to a token character. -% -% |\lst@lastother| is equivalent to |\@empty| if such a character is not -% available, e.g.~at the beginning of a line. Sometimes an indentifier -% has already been printed after processing the last `other' character, -% i.e.~the character is far, far away. In this case |\lst@lastother| -% equals |\relax|. -% -% \item[0.17] |\lst@outputspace| -% -% Use this predefined \meta{spec.\ token} (obviously for character code -% 32) to test against |\lst@lastother|. -% -% \item[0.20] |\lstum@backslash| -% -% Use this predefined \meta{spec.\ token} (for character code 92) to test -% against |\lst@lastother|. In the replacement text for |\lst@Def| one -% could write |\ifx| |\lst@lastother| |\lstum@backslash| \ldots\ to test -% whether the last character has been a backslash. -% -% \item[0.20] |\lst@SaveOutputDef|\marg{character code}\meta{macro} -% -% Stores the \meta{spec.\ token} corresponding to \meta{character code} -% in \meta{macro}. This is the only safe way to get a correct meaning to -% test against |\lst@lastother|, for example -% |\lst@SaveOutputDef{"5C}\lstum@backslash|. -% -% You'll get a ``runaway argument'' error if \meta{character code} is not -% between 33 and 126 (inclusive). -% \end{syntax} -% Now let's turn to the macros dealing a bit more with the output data and -% state. -% \begin{syntax} -% \item[1.0] |\lst@XPrintToken| -% -% outputs the current character string and resets it. This macro keeps -% track of all variables described here. -% -% \item[0.18,,token] |\lst@token| -% -% contains the current character string. Each `character' usually -% expands to its printable version, but it must expand to a character -% token if |\lst@UM| is equivalent to |\@empty|. -% -% \item[0.12,,counter] |\lst@length| -% -% is the length of the current character string. -% -% \item[0.12,,dimension] |\lst@width| -% -% is the width of a single character box. -% -% \item[0.20,,global dimension] |\lst@currlwidth| -% -% is the width of so far printed line. -% -% \item[0.18,,global counter] |\lst@column| -% \item[0.12,,global counter] |\lst@pos| (nonpositive) -% -% |\lst@column|$-$|\lst@pos| is the length of the so far printed line. -% We use two counters since this simplifies tabulator handling: -% |\lst@pos| is a nonpositive representative of `length of so far -% printed line' modulo \keyname{tabsize}. -% It's usually not the biggest nonpositive representative. -% -% \item[0.20] |\lst@CalcColumn| -% -% |\@tempcnta| gets |\lst@column| $-$ |\lst@pos| $+$ |\lst@length|. -% This is the current column number minus one, or the current column -% number zero based. -% -% \item[0.18,,global dimension] |\lst@lostspace| -% -% equals `lost' space: desired current line width minus real line width. -% Whenever this dimension is positive the flexible column format can use -% this space to fix the column alignment. -% \end{syntax} -% -% -% \section{Package extensions}\label{dPackageExtensions} -% -% -% \subsection{Keywords and working identifiers}\label{dKeywordsAndWorkingIdentifiers} -% -% The \aspectname{keywords} aspect defines two main macros. Their respective -% syntax is shown on the left. On the right you'll find examples how the -% package actually defines some keys. -% \begin{syntax} -% \item[0.21] -% \cs{lst@InstallFamily} -% -% \marg{prefix}\syntaxfill \texttt k\\ -% \marg{name}\syntaxfill |{keywords}|\\ -% \marg{style name}\syntaxfill |{keywordstyle}|\\ -% \marg{style init}\syntaxfill |\bfseries|\\ -% \marg{default style name}\syntaxfill |{keywordstyle}|\\ -% \marg{working procedure}\syntaxfill |{}|\\ -% \meta{\alternative{l,o}}\syntaxfill |l|\\ -% \meta{\alternative{d,o}}\syntaxfill |d| -% -% installs either a keyword or `working' class of identifiers according -% to whether \meta{working procedure} is empty. -% -% The three keys \meta{name}, \keyname{more}\meta{name} and -% \keyname{delete}\meta{name}, and if not empty \meta{style name} are -% defined. The first order member of the latter one is initialized with -% \meta{style init} if not equivalent to |\relax|. If the user leaves a -% class style undefined, \meta{default style name} is used instead. -% Thus, make sure that this style is always defined. In the example, -% the first order keywordstyle is set to |\bfseries| and is the default -% for all other classes. -% -% If \meta{working procedure} is not empty, this code is executed when -% reaching such an (user defined) identifier. \meta{working procedure} -% takes exactly one argument, namely the class number to which the -% actual identifier belongs to. If the code uses variables and requires -% values from previous calls, you must define these variables -% |\global|ly. It's not sure whether working procedures are executed -% inside a (separate) group or not. -% -% \texttt l indicates a language key, i.e.~the lists are reset every -% language selection. \texttt o stands for `other' key. -% The keyword respectively working test is either installed at the -% \hookname{DetectKeyword} or \hookname{Output} hook according to -% \meta{\alternative{d,o}}. -% -% \item[0.20] -% \cs{lst@InstallKeywords} -% -% \marg{prefix}\syntaxfill \texttt{cs}\\ -% \marg{name}\syntaxfill |{texcs}|\\ -% \marg{style name}\syntaxfill |{texcsstyle}|\\ -% \marg{style init}\syntaxfill |\relax|\\ -% \marg{default style name}\syntaxfill |{keywordstyle}|\\ -% \marg{working procedure}\syntaxfill see below\\ -% \meta{\alternative{l,o}}\syntaxfill |l|\\ -% \meta{\alternative{d,o}}\syntaxfill |d| -% -% Same parameters, same functionality with one execption. The macro -% installs exactly one keyword class and not a whole family. Therefore -% the argument to \meta{working procedure} is constant (currently empty). -% -% The working procedure of the example reads as follows.\vspace*{-.5\baselineskip} -% \begin{verbatim} -% {\ifx\lst@lastother\lstum@backslash -% \let\lst@thestyle\lst@texcsstyle -% \fi}\end{verbatim} -%\vspace*{-.5\baselineskip} -% What does this procedure do? First of all it is called only if a -% keyword from the user supplied list (or language definition) is found. -% The procedure now checks for a preceding backslash and sets the output -% style accordingly. -% -%\iffalse -% \item[0.20] |\lst@InstallTest|\marg{prefix}\syntaxbreak -% |\lst@|\meta{name}|@list||\lst@|\meta{name}~|\lst@g|\meta{name}|@list||\lst@g|\meta{name}\syntaxbreak -% |\lst@g|\meta{name}|@sty|~\meta{\alternative{w,s}}\meta{\alternative{d,o}} -% -% installs a `working identifier' test or keyword style depending on -% \meta{\alternative{w,s}}. |\lst@g|\meta{name}|@sty| contains the -% working procedure or style macro. Note that the behaviour of the tests -% depends on the \texttt{savemem} option. -% The keyword respectively working test is either installed at the -% \hookname{DetectKeyword} or \hookname{Output} hook according to -% \meta{\alternative{d,o}}. -% -%^^A Either each call of this macro or each different \meta{prefix} inserts -%^^A another test (depending on the \texttt{savemem} option). -% -% |\lst@|\meta{name} contains the current identifier list and -% |\lst@|\meta{name}|@list| a `|\lst@|\meta{$n_i$}|\lst@g|\meta{$n_i$}' -% sequence of currently used classes. If no other classes are used, -% this equals |\lst@|\meta{name}|\lst@g|\meta{name}. The global versions -% |\lst@g|\ldots\ are used to keep track of the keywords. -% (This description needs improvement.) -%\fi -% \end{syntax} -% -% -% \subsection{Delimiters} -% -% We describe two stages: adding a new delimiter type to an existing class of -% delimiters and writing a new class. Each class has its name; currently exist -% \texttt{Comment}, \texttt{String}, and \texttt{Delim}. As you know, the -% latter and the first both provide the type \texttt l, but there is no string -% which starts with the given delimiter and ends at end of line. So we'll add -% it now! -% -% First of all we extend the list of string types by -% \begin{verbatim} -% \lst@AddTo\lst@stringtypes{,l}\end{verbatim} -% Then we must provide the macro which takes the user supplied delimiter and -% makes appropriate definitions. The command name consists of the prefix -% |\lst@|, the delimiter name, |DM| for using dynamic modes, and |@| followed -% by the type. -% \begin{verbatim} -% \gdef\lst@StringDM@l#1#2\@empty#3#4#5{% -% \lst@CArg #2\relax\lst@DefDelimB{}{}{}#3{#1}{#5\lst@Lmodetrue}}\end{verbatim} -% You can put these three lines into a \texttt{.sty}-file or surround them by -% |\makeatletter| and |\makeatother| in the preamble of a document. -% And that's all! -%{\makeatletter -%\lst@AddTo\lst@stringtypes{,l} -%\gdef\lst@StringDM@l#1#2\@empty#3#4#5{^^A -% \lst@CArg #2\relax\lst@DefDelimB{}{}{}#3{#1}{#5\lst@Lmodetrue}} -%} -% \begin{lstsample}{}{} -% \lstset{string=[l]//} -% \begin{lstlisting} -% // This is a string. -% This isn't a string. -% \end{lstlisting} -% \end{lstsample} -% You want more details, of course. Let's begin with the arguments. -% \begin{itemize} -% \item The first argument \emph{after} |\@empty| is used to start the -% delimiter. It's provided by the delimiter class. -% \item The second argument \emph{after} |\@empty| is used to end the -% delimiter. It's also provided by the delimiter class. We didn't -% need it in the example, see the explanation below. -% \item The third argument \emph{after} |\@empty| is -% \marg{style}\meta{start tokens}. -% This with a preceding |\def\lst@currstyle| is used as argument to -% |\lst@EnterMode|. The delimiter class also provides it. In the -% example we `extended' |#5| by |\lst@Lmodetrue| (line mode true). -% The mode automatically ends at end of line, so we didn't need the -% end-delimiter argument. -% \end{itemize} -% And now for the other arguments. In case of dynamic modes, the first argument -% is the mode number. Then follow the user supplied delimiter(s) whose number -% must match the remaining arguments up to |\@empty|. For non-dynamic modes, -% you must either allocate a static mode yourself or use a predefined mode -% number. The delimiters then start with the first argument. -% -% Eventually let's look at the replacement text of the macro. The sequence -% |\lst@CArg #2\relax| puts two required arguments after |\lst@DefDelimB|. -% The syntax of the latter macro is -% \begin{syntax} -% \item[1.0] \cs{lst@DefDelimB} -% -% |{|\meta{1st}\meta{2nd}\marg{rest}|}|\syntaxfill |{//{}}|\\ -% \meta{save 1st}\syntaxfill |\lst@c/0|\\ -% \marg{execute}\syntaxfill|{}|\\ -% \marg{delim~exe~modetrue}\syntaxfill|{}|\\ -% \marg{delim~exe~modefalse}\syntaxfill|{}|\\ -% \meta{start-delimiter macro}\syntaxfill|#3|\\ -% \meta{mode number}\syntaxfill |{#1}|\\ -% |{|\marg{style}\meta{start tokens}|}|\syntaxfill |{#5\lst@Lmodetrue}| -% -% defines \meta{1st}\meta{2nd}\meta{rest} as starting-delimiter. -% \meta{execute} is executed when the package comes to \meta{1st}. -% \meta{delim~exe~modetrue} and \meta{delim~exe~modefalse} are -% executed only if the whole delimiter \meta{1st}\meta{2nd}\meta{rest} -% is found. Exactly one of them is called depending on |\lst@ifmode|. -% -% By default the package enters the mode if the delimiter is found -% \emph{and} |\lst@ifmode| is false. Internally we make an appropriate -% definition of |\lst@bnext|, which can be gobbled by placing -% |\@gobblethree| at the very end of \meta{delim exe modefalse}. -% One can provide an own definition (and gobble the default). -% -% \meta{save 1st} must be an undefined macro and is used internally to -% store the previous meaning of \meta{1st}. The arguments \meta{2nd} -% and/or \meta{rest} are empty if the delimiter has strictly less than -% three characters. All characters of \meta{1st}\meta{2nd}\meta{rest} -% must already be active (if not empty). -% That's not a problem since the macro |\lst@CArgX| does this job. -% -% \item[1.0] \cs{lst@DefDelimE} -% -% |{|\meta{1st}\meta{2nd}\marg{rest}|}|\\ -% \meta{save 1st}\\ -% \marg{execute}\\ -% \marg{delim~exe~modetrue}\\ -% \marg{delim~exe~modefalse}\\ -% \meta{end-delimiter macro}\\ -% \meta{mode number} -% -% Ditto for ending-delimiter with slight differences: -% \meta{delim~exe~modetrue} and \meta{delim~exe~modefalse} are executed -% depending on whether |\lst@mode| equals \meta{mode}. -% -% The package ends the mode if the delimiter is found and |\lst@mode| -% equals \meta{mode}. Internally we make an appropriate definition of -% |\lst@enext| (not |\lst@bnext|), which can be gobbled by placing -% |\@gobblethree| at the very end of \meta{delim exe modetrue}. -% -% \item[1.0] \cs{lst@DefDelimBE} -% -% followed by the same eight arguments as for |\lst@DefDelimB| and \ldots\\ -% \meta{end-delimiter macro} -% -% This is a combination of |\lst@DefDelimB| and |\lst@DefDelimE| for the -% case of starting and ending delimiter being the same. -% \end{syntax} -% We finish the first stage by examining two easy examples. -% \texttt d-type strings are defined by -% \begin{verbatim} -% \gdef\lst@StringDM@d#1#2\@empty#3#4#5{% -% \lst@CArg #2\relax\lst@DefDelimBE{}{}{}#3{#1}{#5}#4}\end{verbatim} -% (and an entry in the list of string types). -% Not a big deal. Ditto \texttt d-type comments: -% \begin{verbatim} -% \gdef\lst@CommentDM@s#1#2#3\@empty#4#5#6{% -% \lst@CArg #2\relax\lst@DefDelimB{}{}{}#4{#1}{#6}% -% \lst@CArg #3\relax\lst@DefDelimE{}{}{}#5{#1}}\end{verbatim} -% Here we just need to use both |\lst@DefDelimB| and |\lst@DefDelimE|. -% \goodbreak -% -% So let's get to the second stage. For illustration, here's the definition of -% the \texttt{Delim} class. The respective first argument to the service macro -% makes it delete all delimiters of the class, add the delimiter, or delete -% the particular delimiter only. -% \begin{verbatim} -% \lst@Key{delim}\relax{\lst@DelimKey\@empty{#1}} -% \lst@Key{moredelim}\relax{\lst@DelimKey\relax{#1}} -% \lst@Key{deletedelim}\relax{\lst@DelimKey\@nil{#1}}\end{verbatim} -% The service macro itself calls another macro with appropriate arguments. -% \begin{verbatim} -% \gdef\lst@DelimKey#1#2{% -% \lst@Delim{}#2\relax{Delim}\lst@delimtypes #1% -% {\lst@BeginDelim\lst@EndDelim} -% i\@empty{\lst@BeginIDelim\lst@EndIDelim}}\end{verbatim} -% We have to look at those arguments. Above you can see the actual arguments -% for the \texttt{Delim} class, below are the \texttt{Comment} class ones. -% Note that the user supplied value covers the second and third line of -% arguments. -% \begin{syntax} -% \item[0.21,,changed] -% \cs{lst@Delim} -% -% \meta{default style macro}\syntaxfill \cs{lst@commentstyle}\\ \relax -% [\texttt*[\texttt*]]\texttt[\meta{type}\texttt][\texttt[\meta{style}\texttt][\texttt[\meta{type option}\texttt]]]\\ -% \meta{delimiter\textup(s\textup)}\cs{relax}\syntaxfill|#2|\cs{relax}\\ -% \marg{delimiter name}\syntaxfill|{Comment}|\\ -% \meta{delimiter types macro}\syntaxfill\texttt{\cs{lst@commenttypes}}\\ -% \alternative{\cs{@empty},\cs{@nil},\cs{relax}}\syntaxfill|#1|\\ -% \marg{begin- and end-delim macro}\syntaxfill|{|\cs{lst@BeginComment}\cs{lst@EndComment}|}|\\ -% \meta{extra prefix}\syntaxfill |i|\\ -% \meta{extra conversion}\syntaxfill |\@empty|\\ -% \marg{begin- and end-delim macro}\syntaxfill|{|\cs{lst@BeginIComment}\cs{lst@EndIComment}|}| -% -% Most arguments should be clear. We'll discuss the last four. Both -% \marg{begin- and end-delim macro} must contain exactly two control -% sequences, which are given to |\lst@|\meta{name}[|DM|]|@|\meta{type} -% to begin and end a delimiter. These are the arguments |#3| and |#4| in our -% first example of |\lst@StringDM@l|. Depending on whether the user chosen -% type starts with \meta{extra prefix}, the first two or the last control -% sequences are used. -% -% By default the package takes the delimiter(s), makes the characters active, -% and places them after |\lst@|\meta{name}[|DM|]|@|\meta{type}. If the user -% type starts with \meta{extra prefix}, \meta{extra conversion} might change -% the definition of |\lst@next| to choose a different conversion. The default -% is equivalent to |\lst@XConvert| with |\lst@false|. -% -% Note that \meta{type} never starts with \meta{extra prefix} since it is -% discarded.

Moreover \emph{you} must install a way to detect the end of the -% source code. If you've reached the end, you must \ldots -% \item \ldots\ call |\lst@DeInit| to shutdown the kernel safely. -% \item \meta{Do whatever you want.} -% \item Close the group from the beginning. -% \end{enumerate} -% For example, consider the |\lstinline| command in case of being not inside an -% argument. Then the steps are as follows. -% \begin{enumerate} -% \item |\leavevmode\bgroup| opens a group. -% \item |\def\lst@boxpos{b}| `baseline' aligns the listing. -% \item |\lsthk@PreSet| -% \item |\lstset{flexiblecolumns,#1}| (|#1| is the user provided -% key=value list) -% \item |\lsthk@TextStyle| deactivates all features not safe here. -% \item |\lst@Init\relax| -% \item |\lst@Def{`#1}{\lst@DeInit\egroup}| installs the `end inline' -% detection, where |#1| is the next character after |\lstinline|. -% Moreover chr(13) is redefined to end the fragment in the same way but -% also issues an error message. -% \item Now comes the source code and \ldots -% \item \ldots\ |\lst@DeInit| (from |\lst@Def| above) ends the code snippet -% correctly. -% \item Nothing. -% \item |\egroup| (also from |\lst@Def|) closes the group. -% \end{enumerate} -% The real definition is different since we allow source code inside arguments. -% Read also section \ref{iTheInputCommand} if you really want to write -% pretty-printing commands. -% -% -% \section{Useful internal definitions}\label{dUsefulInternalDefinitions} -% -% This section requires an update. -% -% -% \subsection{General purpose macros}\label{dGeneralPurposeMacros} -% -% \begin{syntax} -% \item[0.19] |\lst@AddTo|\meta{macro}\marg{\TeX~material} -% -% adds \meta{\TeX~material} globally to the contents of \meta{macro}. -% -% \item[0.20] |\lst@Extend|\meta{macro}\marg{\TeX~material} -% -% calls |\lst@AddTo| after the first token of \meta{\TeX~material} is -% |\expand|ed|after|.

Each sequence $a_i$ inside the first -% macro is (locally) replaced by $b_i$. -% The suffix |Arg| refers to the \emph{braced} second argument instead of -% a (nonbraced) macro. It's a hint that we get the `real' argument and -% not a `pointer' to the argument. -% -% \item[0.20] |\lst@IfSubstring|\marg{character sequence}\meta{macro}\marg{then}\marg{else} -% -% \meta{then} is executed if \meta{character sequence} is a substring of -% the contents of \meta{macro}.

lost contact with Carsten Heinz in late 2004, shortly after +% he released version 1.3b of the \packagename{listings} package. After many +% attempts to reach him had failed, Hendri Adriaens took over maintenance of +% the package in accordance with the LPPL's procedure for abandoned packages. +% He then passed the maintainership of the package to Brooks Moses, who had +% volunteered for the position while this procedure was going through. +% +% This release, version 1.4, is the first substantial bugfix release since +% I accepted maintainership of the package. I would like to thank the +% numerous people who reported bugs to me, and particularly those who +% suggested fixes. Thanks in addition to those who provided +% new language definitions and suggestions for improvements. +% +% \paragraph{News and changes} +% Version 1.4 is the fourth bugfix release. There are no substantial changes +% in this version, but a number of minor changes and fixes. The primary news +% is that the documentation has been substantially copyedited, and improved +% in a number of ways to document workarounds and things learned from the +% recent bug reports. +% +% A |numberbychapter| key has been added, to control whether listings are +% numbered sequentially or by chapter in document classes that provide +% chapters. +% +% The |\lstMakeShortInline| command can be used to define single-character +% inline-listing macros, much like the \packagename{shortvrb} package +% allows for verbatim inline text. +% +% A new |spaceflexible| column alignment style has been added, which is +% similar to the |flexible| style except that it only inserts extra space +% to recover the column alignment at locations where there is already +% existing space. +% +% A |s| string type has been added, akin to the |s| comment type. This is +% used in the Ruby language definition. +% +% The |\lst@for| routine has been sped up substantially, thanks to some code +% provided by Hendri Adriaens. Hopefully this will result in a significant +% speedup of the runtime of the overall package. +% +% Among the bugs fixed are the |*| option to |texcs|, which was quite badly +% broken; the interaction of background colors with inline listings and with +% frames; listing captions being broken in AMS document classes; and better +% integration of the list of listings with KOMAscript document class and other +% document clases that use the |\float@addtolists| mechanism. +% +% The following languages were added: |command.com| (DOS/Windows) batch files, +% Common Intermediate Language, Lingo, Postscript, PSTricks, and SPARQL. +% The following dialects of existing languages were added: Ada (2005), +% Assembler (Motorola68k), and Mathematica (5.2). The definitions for ABAP, +% Fortran, Octave, Python, Ruby, and TCL have been improved. Thanks go to the +% contributers. +% +% \vfill +% \paragraph{Thanks} +% There are many people I have to thank for fruitful communication, posting +% their ideas, giving error reports, adding programming languages to +% \texttt{lstdrvrs.dtx}, and so on. Their names are listed in section +% \ref{uClosingAndCredits}. +% +% \paragraph{Trademarks} +% Trademarks appear throughout this documentation without any trademark +% symbol; they are the property of their respective trademark owner. +% There is no intention of infringement; the usage is to the benefit of the +% trademark owner. +% +% +% \clearpage +% +% +% \part{User's guide} +% +% +% \section{Getting started}\label{uGettingStarted} +% +% +% \subsection{A minimal file}\label{uAMinimalFile} +% +% Before using the \packagename{listings} package, you should be familiar with +% the \LaTeX\ typesetting system. You need not to be an expert. +% Here is a minimal file for \packagename{listings}. +% \begin{verbatim} +% \documentclass{article} +% \usepackage{listings} +% +% \begin{document} +% \lstset{language=Pascal} +% +% % Insert Pascal examples here. +% +% \end{document}\end{verbatim} +% Now type in this first example and run it through \LaTeX. +% \begin{advise} +% \item Must I do that really? +% \advisespace +% Yes and no. Some books about programming say this is good. +% What a mistake! Typing takes time---which is wasted if the code is clear to +% you. And if you need that time to understand what is going on, the +% author of the book should reconsider the concept of presenting the +% crucial things---you might want to say that about this guide even---or +% you're simply inexperienced with programming. If only the latter case +% applies, you should spend more time on reading (good) books about +% programming, (good) documentations, and (good) source code from other +% people. Of course you should also make your own experiments. +% You will learn a lot. However, running the example through \LaTeX\ +% shows whether the \packagename{listings} package is installed correctly. +% \item The example doesn't work. +% \advisespace +% Are the two packages \packagename{listings} and \packagename{keyval} +% installed on your system? Consult the administration tool of your +% \TeX\ distribution, your system administrator, the local \TeX\ and +% \LaTeX\ guides, a \TeX\ FAQ, and section \ref{rInstallation}---in +% that order. If you've checked \emph{all} these sources and are +% still helpless, you might want to write a post to a \TeX\ newsgroup +% like \texttt{comp.text.tex}. +% \item Should I read the software license before using the package? +% \advisespace +% Yes, but read this \emph{Getting started} section first to decide +% whether you are willing to use the package.^^A ;-) +% \end{advise} +% +% +% \subsection{Typesetting listings} +% +% Three types of source codes are supported: code snippets, code segments, and +% listings of stand alone files. Snippets are placed inside paragraphs and the +% others as separate paragraphs---the difference is the same as between text +% style and display style formulas. +% \begin{advise} +% \item No matter what kind of source you have, if a listing contains national +% characters like \'e, \L, \"a, or whatever, you must tell the +% package about it! Section \lstref{uSpecialCharacters} discusses this issue. +% \end{advise} +% +% \paragraph{Code snippets} +% The well-known \LaTeX\ command |\verb| typesets code snippets verbatim. +% The new command |\lstinline| pretty-prints the code, for example +%`\lstinline!var i:integer;!' is typeset by +%`{\rstyle|\lstinline|}|!var i:integer;!|'. The exclamation marks delimit +% the code and can be replaced by any character not in the code; +% |\lstinline$var i:integer;$| gives the same result. +% +% \paragraph{Displayed code} +% The \texttt{lstlisting} environment typesets the enclosed source code. Like +% most examples, the following one shows verbatim \LaTeX\ code on the right +% and the result on the left. You might take the right-hand side, put it into +% the minimal file, and run it through \LaTeX. +% \begin{lstsample}[lstlisting]{}{} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% It can't be easier. +% \begin{advise} +% \item That's not true. The name `\texttt{listing}' is shorter. +% \advisespace +% Indeed. But other packages already define environments with that name. +% To be compatible with such packages, all commands and environments of +% the \packagename{listings} package use the prefix `\texttt{lst}'. +% \end{advise} +% The environment provides an optional argument. It tells the package to +% perform special tasks, for example, to print only the lines 2--5: +% \begin{lstsample}{\lstset{frame=trbl,framesep=0pt}\label{gFirstKey=ValueList}}{} +% \begin{lstlisting}[firstline=2, +% lastline=5] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item Hold on! Where comes the frame from and what is it good for? +% \advisespace +% You can put frames around all listings except code snippets. +% You will learn how later. The frame shows that empty lines at the end +% of listings aren't printed. This is line 5 in the example. +% \item Hey, you can't drop my empty lines! +% \advisespace +% You can tell the package not to drop them: +% The key `\ikeyname{showlines}' controls these empty lines and is +% described in section \ref{rTypesettingListings}. Warning: First +% read ahead on how to use keys in general. +% \item I get obscure error messages when using `\ikeyname{firstline}'. +% \advisespace +% That shouldn't happen. Make a bug report as described in section +% \lstref{uTroubleshooting}. +% \end{advise} +% +% \paragraph{Stand alone files} +% Finally we come to |\lstinputlisting|, the command used to pretty-print +% stand alone files. It has one optional and one file name argument. +% Note that you possibly need to specify the relative path to the file. +% Here now the result is printed below the verbatim code since both together +% don't fit the text width. +% \begin{lstsample}{\lstset{comment=[l]\%,columns=fullflexible}}{\lstset{alsoletter=\\,emph=\\lstinputlisting,emphstyle=\rstyle}\lstaspectindex{\lstinputlisting}{}} +% \lstinputlisting[lastline=4]{listings.sty} +% \end{lstsample} +% \begin{advise} +% \item The spacing is different in this example. +% \advisespace +% Yes. The two previous examples have aligned columns, i.e.~columns with +% identical numbers have the same horizontal position---this package +% makes small adjustments only. The columns in the example here are not +% aligned. This is explained in section \ref{uFixedAndFlexibleColumns} +% (keyword: full flexible column format). +% \end{advise} +% +% Now you know all pretty-printing commands and environments. It remains +% to learn the parameters which control the work of the \packagename{listings} +% package. This is, however, the main task. Here are some of them. +% +% +% \subsection{Figure out the appearance}\label{gFigureOutTheAppearance} +% +% Keywords are typeset bold, comments in italic shape, and spaces in strings +% appear as \textvisiblespace. You don't like these settings? Look at this: +%\ifcolor +% \begin{lstxsample}[basicstyle,keywordstyle,identifierstyle,commentstyle,stringstyle,showstringspaces] +% \lstset{% general command to set parameter(s) +% basicstyle=\small, % print whole listing small +% keywordstyle=\color{black}\bfseries\underbar, +% % underlined bold black keywords +% identifierstyle=, % nothing happens +% commentstyle=\color{white}, % white comments +% stringstyle=\ttfamily, % typewriter type for strings +% showstringspaces=false} % no special string spaces +% \end{lstxsample} +%\else +% \begin{lstxsample}[basicstyle,keywordstyle,identifierstyle,commentstyle,stringstyle,showstringspaces] +% \lstset{% general command to set parameter(s) +% basicstyle=\small, % print whole listing small +% keywordstyle=\bfseries\underbar, +% % underlined bold keywords +% identifierstyle=, % nothing happens +% commentstyle=\itshape, % default +% stringstyle=\ttfamily, % typewriter type for strings +% showstringspaces=false} % no special string spaces +% \end{lstxsample} +%\fi +% \begin{lstsample}{}{} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +%\ifcolor +% \begin{advise} +% \item You've requested white coloured comments, but I can see the comment +% on the left side. +% \advisespace +% There are a couple of possible reasons: +% (1) You've printed the documentation on nonwhite paper. +% (2) If you are viewing this documentation as a \texttt{.dvi}-file, your +% viewer seems to have problems with colour specials. Try to print +% the page on white paper. +% (3) If a printout on white paper shows the comment, the colour +% specials aren't suitable for your printer or printer driver. +% Recreate the documentation and try it again---and ensure that +% the \packagename{color} package is well-configured. +% \end{advise} +%\fi +% The styles use two different kinds of commands. |\ttfamily| and |\bfseries| +% both take no arguments but |\underbar| does; it underlines the following +% argument. In general, the \emph{very last} command may read exactly one +% argument, namely some material the package typesets. There's one exception. +% The last command of \ikeyname{basicstyle} \emph{must not} read any +% tokens---or you will get deep in trouble. +% \begin{advise} +% \item `|basicstyle=\small|' looks fine, but comments look really bad with +% `|commentstyle=\tiny|' and empty basic style, say. +% \advisespace +% Don't use different font sizes in a single listing. +% \item But I really want it! +% \advisespace +% No, you don't. +%^^A The package adjusts internal data after selecting the basic style at +%^^A the beginning of each listing. This is a problem if you change the +%^^A font size for comments or strings, for example. +%^^A Section \ref{rColumnAlignment} shows how to overcome this. +%^^A But once again: Don't use different font sizes in a single listing +%^^A unless you really know what you are doing. +% \end{advise} +% +% \paragraph{Warning}\label{wStrikingStyles} +% You should be very careful with striking styles; the recent example is rather +% moderate---it can get horrible. \emph{Always use decent highlighting.} +% Unfortunately it is difficult to give more recommendations since they depend +% on the type of document you're creating. Slides or other presentations often +% require more striking styles than books, for example. +% In the end, it's \emph{you} who have to find the golden mean! +% +% +% \subsection{Seduce to use}\label{gSeduceToUse} +% +% You know all pretty-printing commands and some main parameters. Here now +% comes a small and incomplete overview of other features. The table of +% contents and the index also provide information. +% +% \paragraph{Line numbers} +% are available for all displayed listings, e.g.~tiny numbers on the left, each +% second line, with 5pt distance to the listing: +% \begin{lstxsample}[numbers,numberstyle,stepnumber,numbersep] +% \lstset{numbers=left, numberstyle=\tiny, stepnumber=2, numbersep=5pt} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item I can't get rid of line numbers in subsequent listings. +% \advisespace +% `|numbers=none|' turns them off. +% \item Can I use these keys in the optional arguments? +% \advisespace +% Of course. Note that optional arguments modify values for one +% particular listing only: you change the appearance, step or distance +% of line numbers for a single listing. The previous values are +% restored afterwards. +% \end{advise} +% The environment allows you to interrupt your listings: you can end a listing +% and continue it later with the correct line number even if there are other +% listings in between. Read section \ref{uLineNumbers} for a thorough +% discussion. +% +% \paragraph{Floating listings} +% Displayed listings may float: +% \begin{lstsample}{\lstset{frame=tb}}{} +% \begin{lstlisting}[float,caption=A floating example] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% Don't care about the parameter \ikeyname{caption} now. And if you put the +% example into the minimal file and run it through \LaTeX, please don't wonder: +% you'll miss the horizontal rules since they are described elsewhere. +% \begin{advise} +% \item \LaTeX's float mechanism allows one to determine the placement of floats. +% How can I do that with these? +% \advisespace +% You can write `|float=tp|', for example. +% \end{advise} +% +% \paragraph{Other features} +% There are still features not mentioned so far: automatic breaking of long +% lines, the possibility to use \LaTeX\ code in listings, automated indexing, +% or personal language definitions. +% One more little teaser? Here you are. But note that the result is not +% produced by the \LaTeX\ code on the right alone. The main parameter is +% hidden. +% \begin{lstsample}{\lstset{literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1}}{} +% \begin{lstlisting} +% if (i<=0) then i := 1; +% if (i>=0) then i := 0; +% if (i<>0) then i := 0; +% \end{lstlisting} +% \end{lstsample} +% +% You're not sure whether you should use \packagename{listings}? +% Read the next section! +% +% +% \subsection{Alternatives} +% +% \begin{advise} +% \item Why do you list alternatives? +% \advisespace +% Well, it's always good to know the competitors.^^A :-) +% \item I've read the descriptions below and the \packagename{listings} package +% seems to incorporate all the features. Why should I use one of the +% other programs? +% \advisespace +% Firstly, the descriptions give a taste and not a complete overview, +% secondly, \packagename{listings} lacks some properties, and, ultimately, +% you should use the program matching your needs most precisely. +% \end{advise} +% This package is certainly not the final utility for typesetting source code. +% Other programs do their job very well, if you are not satisfied with +% \packagename{listings}. Some are independent of \LaTeX, others come as +% separate program plus \LaTeX\ package, and others are packages which +% don't pretty-print the source code. The second type includes converters, +% cross compilers, and preprocessors. Such programs create \LaTeX\ files +% you can use in your document or stand alone ready-to-run \LaTeX\ files. +% +% Note that I'm not dealing with any literate programming tools here, which +% could also be alternatives. However, you should have heard of the +% \texttt{WEB} system, the tool Prof.~Donald E.~Knuth developed and made use +% of to document and implement \TeX. +% +% \paragraph{\href{http://www.infres.enst.fr/~demaille/a2ps}{\packagename{a2ps}}} +% started as `ASCII to PostScript' converter, but today you can invoke the +% program with \texttt{--pretty-print=}\meta{language} option. If your +% favourite programming language is not already supported, you can write your +% own so-called style sheet. You can request line numbers, borders, headers, +% multiple pages per sheet, and many more. You can even print symbols like +% $\forall$ or $\alpha$ instead of their verbose forms. If you just want +% program listings and not a document with some listings, this is the best +% choice. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/nonfree/support/lgrind}{\packagename{LGrind}}} +% is a cross compiler and comes with many predefined programming languages. +% For example, you can put the code on the right in your document, invoke +% \packagename{LGrind} with \texttt{-e} option (and file names), and run the +% created file through \LaTeX. You should get a result similar to the +% left-hand side: +% \begin{center} +% \begin{minipage}{0.45\linewidth} +%\iflgrind +% \LGindent=0pt +% \LGinlinefalse\LGbegin\lgrinde +% \L{\LB{\K{for}_\V{i}:=\V{maxint}_\K{to}_\N{0}_\K{do}}} +% \L{\LB{\K{begin}}} +% \L{\LB{____\C{}\{_do_nothing_\}\CE{}}} +% \L{\LB{\K{end};}} +% \L{\LB{}} +% \L{\LB{\V{Write}(\S{}{'}Case_insensitive_{'}\SE{});}} +% \L{\LB{\V{WritE}(\S{}{'}Pascal_keywords.{'}\SE{});}} +% \endlgrinde\LGend +%\else +% \packagename{LGrind} not installed. +%\fi +% \end{minipage} +% \begin{minipage}{0.45\linewidth} +% \begin{verbatim} +% %[ +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% %]\end{verbatim} +% \end{minipage} +% \end{center} +% If you use |%(| and |%)| instead of |%[| and |%]|, you get a code snippet +% instead of a displayed listing. Moreover you can get line numbers to the +% left or right, use arbitrary \LaTeX\ code in the source code, print symbols +% instead of verbose names, make font setup, and more. You will (have to) +% like it (if you don't like \packagename{listings}). +% +% Note that \packagename{LGrind} contains code with a no-sell license and is +% thus nonfree software. +% +% \paragraph{\href{ftp://axp3.sv.fh-mannheim.de/cvt2latex}{\packagename{cvt2ltx}}} +% is a family of `source code to \LaTeX' converters for C, Objective C, \Cpp, +% IDL and Perl. Different styles, line numbers and other qualifiers can be +% chosen by command-line option. Unfortunately it isn't documented how other +% programming languages can be added. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/support/C++2LaTeX-1_1pl1}{\packagename{\Cpp2\LaTeX}}} +% is a C/\Cpp\ to \LaTeX\ converter. You can specify the fonts for comments, +% directives, keywords, and strings, or the size of a tabulator. But as far as +% I know you can't number lines. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/support/slatex}{\packagename{S\LaTeX}}} +% is a pretty-printing Scheme program (which invokes \LaTeX\ automatically) +% especially designed for Scheme and other Lisp dialects. It supports stand +% alone files, text and display listings, and you can even nest the +% commands/environments if you use \LaTeX\ code in comments, for example. +% Keywords, constants, variables, and symbols are definable and use of +% different styles is possible. No line numbers. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/support/tiny_c2l}{\packagename{tiny\textunderscore c2ltx}}} +% is a C/\Cpp/Java to \LaTeX\ converter based on \packagename{cvt2ltx} (or the +% other way round?). It supports line numbers, block comments, \LaTeX\ code +% in/as comments, and smart line breaking. Font selection and tabulators are +% hard-coded, i.e.~you have to rebuild the program if you want to change the +% appearance. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/misc}{\packagename{listing}}} +% ---note the missing \packagename{s}---is not a pretty-printer and the +% aphorism about documentation at the end of \texttt{listing.sty} is not +% true.\space ^^A :-) +% It defines |\listoflistings| and a nonfloating environment for listings. +% All font selection and indention must be done by hand. However, it's +% useful if you have another tool doing that work, e.g.~\packagename{LGrind}. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/alg}{\packagename{alg}}} +% provides essentially the same functionality as \packagename{algorithms}. +% So read the next paragraph and note that the syntax will be different. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/algorithms}{\packagename{algorithms}}} +% goes a quite different way. You describe an algorithm and the package +% formats it, for example +% \begin{center} +% \begin{minipage}{0.45\linewidth} +%\ifalgorithmicpkg +% \begin{algorithmic} +% \IF {$i\leq0$} +% \STATE $i\gets1$ +% \ELSE\IF {$i\geq0$} +% \STATE $i\gets0$ +% \ENDIF\ENDIF +% \end{algorithmic} +%\else +% \packagename{algorithms} not installed. +%\fi +% \end{minipage} +% \begin{minipage}{0.45\linewidth} +% \begin{verbatim} +%\begin{algorithmic} +%\IF{$i\leq0$} +%\STATE $i\gets1$ +%\ELSE\IF{$i\geq0$} +%\STATE $i\gets0$ +%\ENDIF\ENDIF +%\end{algorithmic}\end{verbatim} +% \end{minipage} +% \end{center} +% As this example shows, you get a good looking algorithm even from a bad +% looking input. The package provides a lot more constructs like |for|-loops, +% |while|-loops, or comments. You can request line numbers, `ruled', `boxed' +% and floating algorithms, a list of algorithms, and you can customize the +% terms \textbf{if}, \textbf{then}, and so on. +% +% \paragraph{\href{http://www.mimuw.edu.pl/~wolinski/pretprin.html}{\packagename{pretprin}}} +% is a package for pretty-printing texts in formal languages---as the title +% in TUGboat, Volume 19 (1998), No.~3 states. It provides environments which +% pretty-print \emph{and} format the source code. Analyzers for Pascal and +% Prolog are defined; adding other languages is easy---if you are or get a bit +% familiar with automatons and formal languages. +% +% \paragraph{\packagename{alltt}} +% defines an environment similar to \texttt{verbatim} except that |\|, |{| and +% |}| have their usual meanings. This means that you can use commands in the +% verbatims, e.g.~select different fonts or enter math mode. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/moreverb}{\packagename{moreverb}}} +% requires \packagename{verbatim} and provides verbatim output to a file, +% `boxed' verbatims and line numbers. +% +% \paragraph{\packagename{verbatim}} +% defines an improved version of the standard \texttt{verbatim} environment and +% a command to input files verbatim. +% +% \paragraph{\href{http://www.ctan.org/tex-archive/macros/latex/contrib/fancyvrb}{\packagename{fancyvrb}}} +% is, roughly speaking, a superset of \packagename{alltt}, +% \packagename{moreverb}, and \packagename{verbatim}, but many more parameters +% control the output. The package provides frames, line numbers on the left or +% on the right, automatic line breaking (difficult), and more. For example, an +% interface to \packagename{listings} exists, i.e.~you can pretty-print source +% code automatically. +% The package \packagename{fvrb-ex} builds on \packagename{fancyvrb} and +% defines environments to present examples similar to the ones in this guide. +% +% +% \section{The next steps}\label{uTheNextSteps} +% +% Now, before actually using the \packagename{listings} package, you should +% \emph{really} read the software license. It does not cost much time and +% provides information you probably need to know. +% +% +% \subsection{Software license}\label{uSoftwareLicense} +% +% The files \texttt{listings.dtx} and \texttt{listings.ins} and all +% files generated from only these two files are referred to as `the +% \packagename{listings} package' or simply `the package'. +% \texttt{lstdrvrs.dtx} and the files generated from that file are +% `drivers'. +% +% \paragraph{Copyright} +% The \packagename{listings} package is copyright 1996--2004 Carsten Heinz, +% and copyright 2006 Brooks Moses. The drivers are copyright any individual +% author listed in the driver files. +% +% \paragraph{Distribution and modification} +% The \packagename{listings} package and its drivers may be distributed +% and/or modified under the conditions of the LaTeX Project Public License, +% either version 1.3 of this license or (at your option) any later version. +% The latest version of this license is in +% \href{http://www.latex-project.org/lppl.txt}{http://www.latex-project.org/lppl.txt} +% and version 1.3 or later is part of all distributions of LaTeX version +% 2003/12/01 or later. +% +% \paragraph{Contacts} +% Read section \lstref{uTroubleshooting} on how to submit a bug report. +% Send all other comments, ideas, and additional programming languages to +% \lstemail\ using \texttt{listings} as part of the subject. +% +% +% \subsection{Package loading}\label{uPackageLoading} +% +% As usual in \LaTeX, the package is loaded by +% |\usepackage[|\meta{options}|]{listings}|, +% where |[|\meta{options}|]| is optional and gives a comma separated list of +% options. Each either loads an additional \packagename{listings} aspect, or +% changes default properties. Usually you don't have to take care of such +% options. But in some cases it could be necessary: if you want to compile +% documents created with an earlier version of this package or if you use +% special features. Here's an incomplete list of possible options. +% \begin{advise} +% \item Where is a list of all of the options? +% \advisespace +% In the developer's guide since they were introduced to debug the +% package more easily. Read section \ref{uHowTos} on how to get that +% guide. +% \end{advise} +% \begin{description} +% \item[\normalfont\texttt{0.21}]\leavevmode +% +% invokes a compatibility mode for compiling documents written for +% \packagename{listings} version 0.21. +% +% \item[\normalfont\texttt{draft}]\leavevmode +% +% The package prints no stand alone files, but shows the captions and +% defines the corresponding labels. +% Note that a global |\documentclass|-option \texttt{draft} is +% recognized, so you don't need to repeat it as a package option. +% +% \item[\normalfont\texttt{final}]\leavevmode\label{uoption:final} +% +% Overwrites a global \texttt{draft} option. +% +% \item[\normalfont\texttt{savemem}]\leavevmode +% +% tries to save some of \TeX's memory. If you switch between languages +% often, it could also reduce compile time. But all this depends on the +% particular document and its listings. +% \end{description} +% Note that various experimental features also need explicit loading via +% options. Read the respective lines in section \ref{rExperimentalFeatures}. +% +% \medbreak +% After package loading it is recommend to load all used dialects of programming +% languages with the following command. It is faster to load several languages +% with one command than loading each language on demand. +% \begin{syntax} +% \item {\rstyle\icmdname\lstloadlanguages}\marg{comma separated list of languages} +% +% Each language is of the form \oarg{dialect}\meta{language}. Without +% the optional \oarg{dialect} the package loads a default dialect. So +% write `|[Visual]C++|' if you want Visual \Cpp\ and `|[ISO]C++|' for +% ISO \Cpp. Both together can be loaded by the command +% |\lstloadlanguages{[Visual]C++,[ISO]C++}|. +% +% Table \ref{uPredefinedLanguages} on page \pageref{uPredefinedLanguages} +% shows all defined languages and their dialects. +% \end{syntax} +%^^A After or even before language loading, you might want to define default +%^^A dialects---just to be independent of configuration files. +% +% +% \subsection{The key=value interface}\label{uTheKey=ValueInterface} +% +% This package uses the \packagename{keyval} package from the +% \packagename{graphics} bundle by David Carlisle. Each parameter is +% controlled by an associated key and a user supplied value. For example, +% \ikeyname{firstline} is a key and |2| a valid value for this key. +% +% The command {\rstyle\icmdname\lstset} gets a comma separated list of +% ``key|=|value'' pairs. The first list with more than a single entry is on +% page \pageref{gFirstKey=ValueList}: |firstline=2,lastline=5|. +% \begin{advise} +% \item So I can write `|\lstset{firstline=2,lastline=5}|' once for all? +% \advisespace +% No. `\ikeyname{firstline}' and `\ikeyname{lastline}' belong to a small +% set of +% keys which are only used on individual listings. However, your command is +% not illegal---it has no effect. You have to use these keys inside the +% optional argument of the environment or input command. +% \item What's about a better example of a key|=|value list? +% \advisespace +% There is one in section \ref{gFigureOutTheAppearance}. +% \item `|language=[77]Fortran|' does not work inside an optional argument. +% \advisespace +% You must put braces around the value if a value with optional argument +% is used inside an optional argument. In the case here write +% `|language={[77]Fortran}|' to select Fortran 77. +% \item If I use the `\ikeyname{language}' key inside an optional argument, the +% language isn't active when I typeset the next listing. +% \advisespace +% All parameters set via `|\lstset|' keep their values up to the end of +% the current environment or group. Afterwards the previous values are +% restored. The optional parameters of the two pretty-printing commands +% and the `\texttt{lstlisting}' environment take effect on the particular +% listing only, i.e.~values are restored immediately. For example, you +% can select a main language and change it for special listings. +% \item \icmdname\lstinline\ has an optional argument? +% \advisespace +% Yes. And from this fact comes a limitation: you can't use the left +% bracket `|[|' as delimiter unless you specify at least an empty +% optional argument as in `|\lstinline[][var i:integer;[|'. +% If you forget this, you will either get a ``runaway argument'' error +% from \TeX, or an error message from the \packagename{keyval} package. +% \end{advise} +% +% +% \subsection{Programming languages}\label{uProgrammingLanguages} +% +% You already know how to activate programming languages---at least Pascal. +% An optional parameter selects particular dialects of a language. For example, +% |language=[77]Fortran| selects Fortran 77 and |language=[XSC]Pascal| does the +% same for Pascal XSC. The general form is +% {\rstyle\ikeyname{language}}|=|\oarg{dialect}\meta{language}. +% If you want to get rid of keyword, comment, and string detection, use +% |language={}| as an argument to |\lstset| or as optional argument. +% +% Table \ref{uPredefinedLanguages} shows all predefined languages and dialects. +% Use the listed names as \meta{language} and \meta{dialect}, respectively. If +% no dialect or `empty' is given in the table, just don't specify a dialect. +% Each underlined dialect is default; it is selected if you leave out +% the optional argument. The predefined defaults are the newest language +% versions or standard dialects. +%^^A +%^^A Make table of predefined languages. +%^^A +%\let\lstlanguages\empty +%\makeatletter +%\@for\lst@temp:={lstlang1.sty,lstlang2.sty,lstlang3.sty}\do +% {\IfFileExists\lst@temp{}{\let\lstlanguages\relax}} +%\makeatother +%\ifx\lstlanguages\relax +% \PackageWarningNoLine{Listings} +% {Standard drivers not available.\MessageBreak +% Please check your installation.\MessageBreak +% Compilation aborted} +% \csname @@end\expandafter\endcsname +%\fi +%\lstscanlanguages\lstlanguages{lstlang1.sty,lstlang2.sty,lstlang3.sty}{}^^A +%\def\topfigrule{\hrule\kern-0.4pt\relax}^^A +%\let\botfigrule\topfigrule +%\belowcaptionskip=\smallskipamount +% \begin{table}[tbhp] +% \small +% \caption{Predefined languages. +% Note that some definitions are preliminary, for example HTML and XML. +% Each underlined dialect is the default dialect.}^^A +% \label{uPredefinedLanguages}^^A +% \makeatletter +% \setbox\@tempboxa\hbox{^^A +% \InputIfFileExists{listings.cfg}{\lst@InputCatcodes}{}}^^A +% \lstprintlanguages\lstlanguages +% \end{table} +%^^A +%^^A end of table +%^^A +%\lstset{defaultdialect=[doc]Pascal}^^A restore +% \begin{advise} +% \item How can I define default dialects? +% \advisespace +% Check section \ref{rLanguagesAndStyles} for `\keyname{defaultdialect}'. +% \item I have C code mixed with assembler lines. Can \packagename{listings} +% pretty-print such source code, i.e.~highlight keywords and comments of +% both languages? +% \advisespace +% `\ikeyname{alsolanguage}|=|\oarg{dialect}\meta{language}' selects a +% language additionally to the active one. So you only have to write a +% language definition for your assembler dialect, which doesn't interfere +% with the definition of C, say. Moreover you might want to use the key +% `\keyname{classoffset}' described in section \ref{rLanguagesAndStyles}. +% \item How can I define my own language? +% \advisespace +% This is discussed in section \ref{rLanguageDefinitions}. And if you +% think that other people could benefit by your definition, you might +% want to send it to the address in section \ref{uSoftwareLicense}. +% Then it will be published under the \LaTeX\ Project Public License. +% \end{advise} +% Note that the arguments \meta{language} and \meta{dialect} are case +% insensitive and that spaces have no effect. +% +% +% \subsection{Special characters}\label{uSpecialCharacters} +% +% +% \paragraph{Tabulators} +% You might get unexpected output if your sources contain tabulators. +% The package assumes tabulator stops at columns 9, 17, 25, 33, and so on. +% This is predefined via |tabsize=8|. If you change the eight to the number +% $n$, you will get tabulator stops at columns $n+1,2n+1,3n+1,$ and so on. +% \begin{lstsample}[tabsize]{}{} +% \lstset{tabsize=2} +% \begin{lstlisting} +% 123456789 +% { one tabulator } +% { two tabs } +% 123 { 123 + two tabs } +% \end{lstlisting} +% \end{lstsample} +% For better illustration, the left-hand side uses |tabsize=2| but the verbatim +% code |tabsize=4|. Note that |\lstset| modifies the values for all following +% listings in the same environment or group. This is no problem here since the +% examples are typeset inside minipages. If you want to change settings for a +% single listing, use the optional argument. +% +% +% \paragraph{Visible tabulators and spaces} +% One can make spaces and tabulators visible: +% \begin{lstsample}[showspaces,showtabs,tab]{}{} +% \lstset{showspaces=true, +% showtabs=true, +% tab=\rightarrowfill} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% If you request \ikeyname{showspaces} but no \ikeyname{showtabs}, +% tabulators are converted to visible spaces. +% The default definition of \ikeyname{tab} produces a `wide visible space' +% \lstinline[showtabs]! !. So you might want to use |$\to$|, |$\dashv$| +% or something else instead. +% \begin{advise} +% \item Some sort of advice: (1) You should really indent lines of source code +% to make listings more readable. (2) Don't indent some lines with +% spaces and others via tabulators. Changing the tabulator size (of your +% editor or pretty-printing tool) completely disturbs the columns. +% (3) As a consequence, never share your files with differently tab sized +% people!^^A true only if you use tabulators, just :-) +% \item To make the \LaTeX\ code more readable, I indent the environments' +% program listings. How can I remove that indention in the output? +% \advisespace +% Read `How to gobble characters' in section \ref{uHowTos}. +% \end{advise} +% +% +% \paragraph{Form feeds} +% Another special character is a form feed causing an empty line by default. +% {\rstyle\ikeyname{formfeed}}|=\newpage| would result in a new page every +% form feed. Please note that such definitions (even the default) might get +% in conflict with frames. +% +% +% \paragraph{National characters} +% If you type in such characters directly as characters of codes 128--255 and +% use them also in listings, let the package know it---or you'll get really +% funny results. {\rstyle\ikeyname{extendedchars}}|=true| allows and +% |extendedchars=false| prohibits \packagename{listings} from handling +% extended characters in listings. If you use them, you should load +% \packagename{fontenc}, \packagename{inputenc} and/or +% any other package which defines the characters. +% \begin{advise} +% \item I have problems using \packagename{inputenc} together with +% \packagename{listings}. +% \advisespace +% This could be a compatibility problem. Make a bug report as described +% in section \lstref{uTroubleshooting}. +% \end{advise} +% The extended characters don't cover Arabic, Chinese, Hebrew, Japanese, and so +% on---specifically, any encoding which uses multiple bytes per character. +% +% Thus, if you use the a package that supports multibyte characters, such as +% the \packagename{CJK} or \packagename {ucs} packages for Chinese and +% UTF-8 characters, you must avoid letting \packagename{listings} +% process the extended characters. It is generally best to also specify +% |extendedchars=false| to avoid having \packagename{listings} get entangled +% in the other package's extended-character treatment. +% +% If you do have a listing contained within a CJK environment, and want to have +% CJK characters inside the listing, you can place them within a comment that +% escapes to \LaTeX -- see section \ref{rEscapingToLaTeX} for how to do that. +% (If the listing is not inside a CJK environment, you can simply put a small +% CJK environment within the escaped-to-\LaTeX portion of the comment.) +% +% Similarly, if you are using UTF-8 extended characters in a listing, they must +% be placed within an escape to \LaTeX. +% +% Also, section \ref{uNationalCharacters} has a few details on how to work with +% extended characters in the context of $\Lambda$. +% +% +% \subsection{Line numbers}\label{uLineNumbers} +% +% You already know the keys \ikeyname{numbers}, \ikeyname{numberstyle}, +% \ikeyname{stepnumber}, and \ikeyname{numbersep} from section +% \ref{gSeduceToUse}. Here now we deal with continued listings. +% You have two options to get consistent line numbering across listings. +% +% \begin{lstsample}[firstnumber]{\lstset{numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} +% \begin{lstlisting}[firstnumber=100] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% \end{lstlisting} +% And we continue the listing: +% \begin{lstlisting}[firstnumber=last] +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% In the example, \ikeyname{firstnumber} is initially set to 100; some lines +% later the value is \texttt{last}, which continues the numbering of the last +% listing. Note that the empty line at the end of the first part is not printed +% here, but it counts for line numbering. You should also notice that you can +% write |\lstset{firstnumber=last}| once and get consecutively numbered code +% lines---except you specify something different for a particular listing. +% +% On the other hand you can use |firstnumber=auto| and name your listings. +% Listings with identical names (case sensitive!) share a line counter. +% \begin{lstsample}[name]{\lstset{numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} +% \begin{lstlisting}[name=Test] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% +% \end{lstlisting} +% And we continue the listing: +% \begin{lstlisting}[name=Test] +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% The next |Test| listing goes on with line number {\makeatletter\lstno@Test}, +% no matter whether there are other listings in between. +% \begin{advise} +% \item Okay. And how can I get decreasing line numbers? +% \advisespace +% Sorry, what? +% \advisespace +% Decreasing line numbers as on page \pageref{rDecreasingLabels}. +% \advisespace +% May I suggest to demonstrate your individuality by other means? +% If you differ, you should try a negative `\ikeyname{stepnumber}' +% (together with `\ikeyname{firstnumber}'). +% \end{advise} +% +% Read section \ref{uHowTos} on how to reference line numbers. +% +% +% \subsection{Layout elements} +% +% It's always a good idea to structure the layout by vertical space, +% horizontal lines, or different type sizes and typefaces. The best to stress +% whole listings are---not all at once---colours, frames, vertical space, and +% captions. The latter are also good to refer to listings, of course. +% +% \paragraph{Vertical space} +% The keys {\rstyle\ikeyname{aboveskip}} and {\rstyle\ikeyname{belowskip}} +% control the vertical space above and below displayed listings. Both keys get +% a dimension or skip as value and are initialized to |\medskipamount|. +% +% \paragraph{Frames} +% The key \ikeyname{frame} takes the verbose values \keyvalue{none}, +% \keyvalue{leftline}, \keyvalue{topline}, \keyvalue{bottomline}, +% \keyvalue{lines} (top and bottom), \keyvalue{single} for single frames, or +% \keyvalue{shadowbox}. +% \begin{lstsample}[frame]{}{} +% \begin{lstlisting}[frame=single] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item The rules aren't aligned. +% \advisespace +% This could be a bug of this package or a problem with your +% \texttt{.dvi} driver. \emph{Before} sending a bug report to the package +% author, modify the parameters described in section \ref{rFrames} +% heavily. And do this step by step! +% For example, begin with `|framerule=10mm|'. If the rules are +% misaligned by the same (small) amount as before, the problem does not +% come from the rule width. So continue with the next parameter. Also, +% Adobe Acrobat sometimes has single-pixel rounding errors which can +% cause small misalignments at the corners when PDF files are displayed +% on screen; these are unfortunately normal. +% \end{advise} +% Alternatively you can control the rules at the \texttt{t}op, \texttt{r}ight, +% \texttt{b}ottom, and \texttt{l}eft directly by using the four initial letters +% for single rules and their upper case versions for double rules. +% \begin{lstsample}[frame]{}{} +% \begin{lstlisting}[frame=trBL] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% Note that a corner is drawn if and only if both adjacent rules are requested. +% You might think that the lines should be drawn up to the edge, but what's +% about round corners? The key \ikeyname{frameround} must get exactly four +% characters as value. The first character is attached to the upper right +% corner and it continues clockwise. `\texttt{t}' as character makes the +% corresponding corner round. +% \begin{lstsample}[frameround]{}{} +% \lstset{frameround=fttt} +% \begin{lstlisting}[frame=trBL] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% Note that \ikeyname{frameround} has been used together with |\lstset| and thus +% the value affects all following listings in the same group or environment. +% Since the listing is inside a \texttt{minipage} here, this is no problem. +% \begin{advise} +% \item Don't use frames all the time, and in particular not with short listings. +% This would emphasize nothing. Use frames for $10\%$ or even less of +% your listings, for your most important ones. +% \item If you use frames on floating listings, do you really want frames? +% \advisespace +% No, I want to separate floats from text. +% \advisespace +% Then it is better to redefine \LaTeX's `|\topfigrule|' and +% `|\botfigrule|'. For example, you could write +% `|\renewcommand*\topfigrule{\hrule\kern-0.4pt\relax}|' and make the +% same definition for |\botfigrule|. +% \end{advise} +% +% \paragraph{Captions} +% Now we come to \ikeyname{caption} and \ikeyname{label}. You might guess +% (correctly) that they can be used in the same manner as \LaTeX's |\caption| +% and |\label| commands, although here it is also possible to have a caption +% regardless of whether or not the listing is in a float: +% \begin{lstsample}[caption,label]{\lstset{xleftmargin=.05\linewidth}}{} +% \begin{lstlisting}[caption={Useless code},label=useless] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% Afterwards you could refer to the listing via |\ref{useless}|. By default +% such a listing gets an entry in the list of listings, which can be printed +% with the command {\rstyle\icmdname\lstlistoflistings}. The key +% {\rstyle\ikeyname{nolol}} suppresses an entry for both the environment or +% the input command. Moreover, you can specify a short caption for the list +% of listings: +% \keyname{caption}|={|\oarg{short}\meta{long}|}|. +% Note that the whole value is enclosed in braces since an optional value is +% used in an optional argument. +% +% If you don't want the label \texttt{\lstlistingname} plus number, you should +% use \ikeyname{title}: +% \begin{lstsample}[title]{\lstset{xleftmargin=.05\linewidth}}{} +% \begin{lstlisting}[title={`Caption' without label}] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item Something goes wrong with `\keyname{title}' in my document: in front of +% the title is a delimiter. +% \advisespace +% The result depends on the document class; some are not compatible. +% Contact the package author for a work-around. +% \end{advise} +% +% \paragraph{Colours} +% One more element. You need the \packagename{color} package and can then +% request coloured background via +% \ikeyname{backgroundcolor}|=|\meta{color command}. +% \begin{advise} +% \item Great! I love colours. +% \advisespace +% Fine, yes, really. And I like to remind you of the warning about +% striking styles on page \pageref{wStrikingStyles}. +% \end{advise} +%\ifcolor +% \begin{lstxsample}[backgroundcolor] +% \lstset{backgroundcolor=\color{yellow}} +% \end{lstxsample} +%\else +% \begin{verbatim} +% color package not installed\end{verbatim} +%\fi +% \begin{lstsample}{}{} +% \begin{lstlisting}[frame=single, +% framerule=0pt] +% for i:=maxint to 0 do +% begin +% j:=square(root(i)); +% end; +% \end{lstlisting} +% \end{lstsample} +% The example also shows how to get coloured space around the whole listing: +% use a frame whose rules have no width. +% +% +% \subsection{Emphasize identifiers}\label{uEmphasizeIdentifiers} +% +% Recall the pretty-printing commands and environment. |\lstinline| prints +% code snippets, |\lstinputlisting| whole files, and \texttt{lstlisting} +% pieces of code which reside in the \LaTeX\ file. And what are these +% different `types' of source code good for? Well, it just happens that a +% sentence contains a code fragment. Whole files are typically included in or +% as an appendix. Nevertheless some books about programming also include such +% listings in normal text sections---to increase the number of pages. +% Nowadays source code should be shipped on disk or CD-ROM and only the main +% header or interface files should be typeset for reference. So, please, don't +% misuse the \packagename{listings} package. But let's get back to the topic. +% +% Obviously `\texttt{lstlisting} source code' isn't used to make an executable +% program from. Such source code has some kind of educational purpose or even +% didactic. +% \begin{advise} +% \item What's the difference between educational and didactic? +% \advisespace +% Something educational can be good or bad, true or false. +% Didactic is true by definition.^^A :-) +% \end{advise} +% Usually \emph{keywords} are highlighted when the package typesets a piece of +% source code. This isn't necessary for readers who know the programming +% language well. The main matter is the presentation of interface, library or +% other functions or variables. If this is your concern, here come the right +% keys. Let's say, you want to emphasize the functions |square| and |root|, +% for example, by underlining them. Then you could do it like this: +% \begin{lstxsample}[emph,emphstyle] +% \lstset{emph={square,root},emphstyle=\underbar} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% j:=square(root(i)); +% end; +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item Note that the list of identifiers |{square,root}| is enclosed in +% braces. Otherwise the \packagename{keyval} package would complain +% about an undefined key \keyname{root} since the comma finishes the +% key=value pair. +% Note also that you \emph{must} put braces around the value if you +% use an optional argument of a key inside an optional argument of a +% pretty-printing command. Though it is not necessary, the following +% example uses these braces. They are typically forgotten when they +% become necessary, +% \end{advise} +% +% Both keys have an optional \meta{class number} argument for multiple +% identifier lists: +%\ifcolor +% \begin{lstxsample}[emph,emphstyle] +% \lstset{emph={square}, emphstyle=\color{red}, +% emph={[2]root,base},emphstyle={[2]\color{blue}}} +% \end{lstxsample} +%\else +% \begin{lstxsample}[emph,emphstyle] +% \lstset{emph={square}, emphstyle=\underbar, +% emph={[2]root,base},emphstyle={[2]\fbox}} +% \end{lstxsample} +%\fi +% \begin{lstsample}{}{} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% j:=square(root(i)); +% end; +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item What is the maximal \meta{class number}? +% \advisespace +% $2^{31}-1=2\,147\,483\,647$. But \TeX's memory will exceed before you +% can define so many different classes. +% \end{advise} +% +% One final hint: Keep the lists of identifiers disjoint. Never use a keyword +% in an `emphasize' list or one name in two different lists. Even if your +% source code is highlighted as expected, there is no guarantee that it is +% still the case if you change the order of your listings or if you use the +% next release of this package. +% +% +%\iffalse +% \subsection{*Listing alignment}\label{uListingAlignment} +% +% The examples are typeset with centered \texttt{minipage}s. That's the reason +% why you can't see that line numbers are printed in the margin. Now we +% separate the minipage margin and the minipage by a vertical rule: +% \begin{lstsample}{\lstset{frame=l,framesep=0pt,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} +% Some text before +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% \end{lstsample} +% The listing is lined up with the normal text. The parameter \ikeyname{xleftmargin} +% moves the listing to the right (or left if the dimension is negative). +% \begin{lstsample}{\lstset{frame=l,framesep=0pt,numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} +% Some text before +% \begin{lstlisting}[xleftmargin=15pt] +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% \end{lstlisting} +% +% \begin{lstlisting}{ } +% Write('Insensitive'); +% WritE('keywords.'); +% \end{lstlisting} +% \end{lstsample} +% Note again that optional arguments change settings for single listings. +% +% If you use environments like \texttt{itemize} or \texttt{enumerate}, there +% is `natural' indention coming from these environments. By default the +% \packagename{listings} package respects this. But you might use +% |resetmargins=true| (or |false|) to make your own decision. You can use it +% together with |xleftmargin|, of course. +% \begin{advise} +% \item I get heavy overfull |\hbox|es from some listings. +% \advisespace +% This comes from long lines in your listings. You have some options +% to get rid of the overful |\hbox|es. Firstly I recommend to typeset +% listings in smaller fonts than the surrounding text, for example +% `|basicstyle=\small|'. Secondly you might want to use the flexible +% column format. Thirdly you can increase the line width or set it +% explicitly, refer section \ref{rMarginsAndLineShape}. +% If all this doesn't help, you might want to change +% `\ikeyname{basewidth}', but be careful! The two unknown items are +% explained in the next section. +% \end{advise} +% +% You might need to control the vertical position of listings with the +% \ikeyname{boxpos} key, for example, if you use them in \texttt{minipage} or +% \texttt{tabular} environments. Here `listings' means \texttt{lstlisting} or +% |\lstinputlisting|. As the following example shows, you can even place such +% listings inside paragraphs, but you must force the package to do this by +% enclosing the listing in |\hbox{| and |}|. +% \begin{advise} +% \item Is it good form to use the \TeX-primitive `|\hbox|' in a \LaTeX\ +% document? +% \advisespace +% No, it's not. But \LaTeX's `|\mbox|' does not work in this example: +% \end{advise} +% \begin{lstsample}{}{} +% Here are some multi-line listings inside a paragraph. +% The `boxpos' key controls their vertical alignment: +% \hbox{\begin{lstlisting}[boxpos=c] +% center +% center +% \end{lstlisting}} +% \hbox{\begin{lstlisting}[boxpos=b] +% bottom baseline +% bottom baseline +% \end{lstlisting}} +% \hbox{\begin{lstlisting}[boxpos=t] +% top baseline +% top baseline +% \end{lstlisting}} +% \end{lstsample} +%\fi +% +% +% \subsection{Indexing}\label{uIndexing} +% +% Indexing is just like emphasizing identifiers---I mean the usage: +% \begin{lstxsample}[index] +% \lstset{index={square},index={[2]root}} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% j:=square(root(i)); +% end; +% \end{lstlisting} +% \end{lstsample} +% Of course, you can't see anything here. You will have to look at the index. +% \begin{advise} +% \item Why is the `\ikeyname{index}' key able to work with multiple identifier +% lists? +% \advisespace +% This question is strongly related to the `{\rstyle\ikeyname{indexstyle}}' +% key. Someone might want to create multiple indexes or want to insert +% prefixes like `|constants|', `|functions|', `|keywords|', and so on. +% The `\ikeyname{indexstyle}' key works like the other style keys except +% that the last token \emph{must} take an argument, namely the +% (printable form of the) current identifier. +% +% You can define `|\newcommand\indexkeywords[1]{\index{keywords, #1}}|' +% and make similar definitions for constant or function names. Then +% `|indexstyle=[1]\indexkeywords|' might meet your purpose. This becomes +% easier if you want to create multiple indexes with the +% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/camel} +% {\packagename{index}} package. +% If you have defined appropriate new indexes, it is possible to write +% `|indexstyle=\index[keywords]|', for example. +% +% \item Let's say, I want to index all keywords. It would be annoying to +% type in all the keywords again, specifically if the used programming +% language changes frequently. +% \advisespace +% Just read ahead. +% \end{advise} +% The \ikeyname{index} key has in fact two optional arguments. The first is the +% well-known \meta{class number}, the second is a comma separated list of other +% keyword classes whose identifiers are indexed. The indexed identifiers then +% change automatically with the defined keywords---not automagically, it's not +% an illusion.^^A :-) +% +% Eventually you need to know the names of the keyword classes. It's usually +% the key name followed by a class number, for example, |emph2|, |emph3|, +% \ldots, |keywords2| or |index5|. But there is no number for the first order +% classes |keywords|, |emph|, |directives|, and so on. +% \begin{advise} +% \item `|index=[keywords]|' does not work. +% \advisespace +% The package can't guess which optional argument you mean. Hence you +% must specify both if you want to use the second one. You should try +% `|index=[1][keywords]|'. +% \end{advise} +% +% +% \subsection{Fixed and flexible columns}\label{uFixedAndFlexibleColumns} +% +% The first thing a reader notices---except different styles for keywords, +% etc.---is the column alignment. Arne John Glenstrup invented the flexible +% column format in 1997. Since then some efforts were made to develop this +% branch farther. Currently four column formats are provided: fixed, flexible, +% space-flexible, and full flexible. Take a close look at the following +% examples. +% \begin{center} +% \lstset{style={},language={}} +% \def\sample{\begin{lstlisting}^^J WOMEN\ \ are^^A +% ^^J \ \ \ \ \ \ \ MEN^^A +% ^^J WOMEN are^^A +% ^^J better MEN^^J \end{lstlisting}} +% \begin{tabular}{@{}c@{\qquad\quad}c@{\qquad\quad}c@{\qquad\quad}c@{}} +% {\rstyle\ikeyname{columns}}|=| & \texttt{fixed} & \texttt{flexible} & \texttt{fullflexible}\\ +% & (at {\makeatletter\lst@widthfixed}) +% & (at {\makeatletter\lst@widthflexible}) +% & (at {\makeatletter\lst@widthflexible})\\ +% \noalign{\medskip} +% \lstset{basicstyle=\ttfamily,basewidth=0.51em}\sample +% & \lstset{columns=fixed}\sample +% & \lstset{columns=flexible}\sample +% & \lstset{columns=fullflexible}\sample +% \end{tabular} +% \end{center} +% \begin{advise} +% \item Why are women better men? +% \advisespace +% Do you want to philosophize? Well, have I ever said that the +% statement ``women are better men'' is true? I can't even remember this +% about ``women are men'' \ldots . ^^A ;-) +% \end{advise} +% In the abstract one can say: The fixed column format ruins the spacing +% intended by the font designer, while the flexible formats ruin the column +% alignment (possibly) intended by the programmer. Common to all is that the +% input characters are translated into a sequence of basic output units like +% \begingroup \lstset{gobble=6,xleftmargin=\leftmargini} +% \makeatletter +%^^A Make \fbox around each output unit. +% \fboxsep=0pt +% \def\lst@alloverstyle#1{\fbox{\kern-\fboxrule\strut#1}\kern-\fboxrule} +% \begin{lstlisting}[basewidth=1em] +% if x=y then write('align') +% else print('align'); +% \end{lstlisting} +% Now, the fixed format puts $n$ characters into a box of width $n\times{} +% $`base width', where the base width is {\makeatletter\lst@widthfixed} in the +% example. The format shrinks and stretches the space between the characters +% to make them fit the box. As shown in the example, some character strings look +% \hbox to 2em{b\hss a\hss d} +% or +% \hbox to 2em{w\hss o\hss r\hss s\hss e}, +% but the output is vertically aligned. +% \endgroup +% +% If you don't need or like this, you should use a flexible format. All +% characters are typeset at their natural width. In particular, they never +% overlap. If a word requires more space than reserved, the rest of the line +% simply moves to the right. The difference between the three formats is that +% the full flexible format cares about nothing else, while the normal flexible +% and space-flexible formats try to fix the column alignment if a character +% string needs less space than `reserved'. The normal flexible format will +% insert make-up space to fix the alignment at spaces, before and after +% identifiers, and before and after sequences of other characters; the +% space-flexible format will only insert make-up space by stretching +% existing spaces. In the flexible example above, the two MENs are vertically +% aligned since some space has been inserted in the fourth line to fix the +% alignment. In the full flexible format, the two MENs are not aligned. +% +% Note that both flexible modes printed the two blanks in the first line as a +% single blank, but for different reasons: the normal flexible format fixes +% the column alignment (as would the space-flexible format), and the full +% flexible format doesn't care about the second space. +% +% +% \section{Advanced techniques}\label{uAdvancedTechniques} +% +% +% \subsection{Style definitions} +% +% It is obvious that a pretty-printing tool like this requires some kind of +% language selection and definition. The first has already been described and +% the latter is convered by the next section. However, it is very convenient +% to have the same for printing styles: at a central place of your document +% they can be modified easily and the changes take effect on all listings. +% +% Similar to languages, +% {\rstyle\ikeyname{style}}|=|\meta{style name} +% activates a previously defined style. A definition is as easy: +% {\rstyle|\lstdefinestyle|}\marg{style name}\marg{key=value list}. +% Keys not used in such a definition are untouched by the corresponding style +% selection, of course. For example, you could write +% \begin{verbatim} +% \lstdefinestyle{numbers} +% {numbers=left, stepnumber=1, numberstyle=\tiny, numbersep=10pt} +% \lstdefinestyle{nonumbers} +% {numbers=none}\end{verbatim} +% and switch from listings with line numbers to listings without ones and vice +% versa simply by |style=nonumbers| and |style=numbers|, respectively. +% \begin{advise} +% \item You could even write +% `|\lstdefinestyle{C++}{language=C++,style=numbers}|'. +% Style and language names are independent of each other and so might +% coincide. Moreover it is possible to activate other styles. +% +% \item It's easy to crash the package using styles. Write +% '|\lstdefinestyle{crash}{style=crash}|' and '|\lstset{style=crash}|'. +% \TeX's capacity will exceed, sorry [parameter stack size]. Only bad +% boys use such recursive calls, but only good girls use this package. +% Thus the problem is of minor interest.^^A :-) +% \end{advise} +% +% +% \subsection{Language definitions}\label{uLanguageDefinitions} +% +% These are like style definitions except for an optional dialect name and an +% optional base language---and, of course, a different command name and +% specialized keys. In the simple case it's +% {\rstyle|\lstdefinelanguage|}\marg{language name}\marg{key=value list}. +% For many programming languages it is sufficient to specify keywords and +% standard function names, comments, and strings. Let's look at an example. +% \begin{lstxsample}[morekeywords,sensitive,morecomment,morestring] +% \lstdefinelanguage{rock} +% {morekeywords={one,two,three,four,five,six,seven,eight, +% nine,ten,eleven,twelve,o,clock,rock,around,the,tonight}, +% sensitive=false, +% morecomment=[l]{//}, +% morecomment=[s]{/*}{*/}, +% morestring=[b]", +% } +% \end{lstxsample} +% \begingroup \csname lst@EndWriteFile\endcsname +% \bigbreak +% +% \noindent +% There isn't much to say about keywords. They are defined like identifiers +% you want to emphasize. Additionally you need to specify whether they are +% case sensitive or not. And yes: you could insert |[2]| in front of the +% keyword \texttt{one} to define the keywords as `second order' and print them +% in |keywordstyle={[2]...}|. +% \begin{advise} +% \item I get a `\texttt{Missing = inserted for }|\ifnum|' error when I select +% my language. +% \advisespace +% Did you forget the comma after `|keywords={...}|'? And if you encounter +% unexpected characters after selecting a language (or style), you have +% probably forgotten a different comma or you have given to many +% arguments to a key, for example, |morecomment=[l]{--}{!}|. +% \end{advise} +% +% So let's turn to comments and strings. Each value starts with a +% \emph{mandatory} \oarg{type} argument followed by a changing number of +% opening and closing delimiters. Note that each delimiter (pair) requires a +% key=value on its own, even if types are equal. Hence, you'll need to insert +% \texttt{morestring=[b]'} if single quotes open and close string or character +% literals in the same way as double quotes do in the example. +% +% Eventually you need to know the types and their numbers of delimiters. The +% reference guide contains full lists, here we discuss only the most common. +% For strings these are {\rstyle\texttt{b}} and {\rstyle\texttt{d}} with one +% delimiter each. This delimiter opens and closes the string and inside a +% string it is either escaped by a \texttt backslash or it is \texttt doubled. +% The comment type {\rstyle\texttt{l}} requires exactly one delimiter, which +% starts a comment on any column. This comment goes up to the end of line. +% The other two most common comment types are {\rstyle\texttt{s}} and +% {\rstyle\texttt{n}} with two delimiters each. The first delimiter opens a +% comment which is terminated by the second delimiter. In contrast to the +% \texttt s-type, \texttt n-type comments can be nested. +% \begin{lstxsample}[b,d,l,s,n] +% \lstset{morecomment=[l]{//}, +% morecomment=[s]{/*}{*/}, +% morecomment=[n]{(*}{*)}, +% morestring=[b]", +% morestring=[d]'} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% "str\"ing " not a string +% 'str''ing ' not a string +% // comment line +% /* comment/**/ not a comment +% (* nested (**) still comment +% comment *) not a comment +% \end{lstlisting} +% \end{lstsample} +% \begin{advise} +% \item Is it \emph{that} easy? +% \advisespace +% Almost. There are some troubles you can run into. For example, if +% `\texttt{-*}' starts a comment line and `\texttt{-*-}' a string +% (unlikely but possible), then you must define the shorter delimiter +% first. +% Another problem: by default some characters are not allowed inside +% keywords, for example `\texttt{-}', `\texttt{:}', `\texttt{.}', and +% so on. The reference guide covers this problem by introducing some +% more keys, which let you adjust the standard character table +% appropriately. But note that white space characters are prohibited +% inside keywords. +% \end{advise} +% Finally remember that this section is only an introduction to language +% definitions. There are more keys and possibilities. +% +% +% \subsection{Delimiters}\label{uDelimiters} +% +% You already know two special delimiter classes: comments and strings. +% However, their full syntax hasn't been described so far. For example, +% \ikeyname{commentstyle} applies to all comments---unless you specify +% something different. The \emph{optional} \oarg{style} argument follows the +% \emph{mandatory} \oarg{type} argument. +%\ifcolor +% \begin{lstxsample} +% \lstset{morecomment=[l][keywordstyle]{//}, +% morecomment=[s][\color{white}]{/*}{*/}} +% \end{lstxsample} +%\else +% \begin{lstxsample} +% \lstset{morecomment=[l][keywordstyle]{//}, +% morecomment=[s][\underbar]{/*}{*/}} +% \end{lstxsample} +%\fi +% \begin{lstsample}{}{} +% \begin{lstlisting} +% // bold comment line +% a single /* comment */ +% \end{lstlisting} +% \end{lstsample} +% As you can see, you have the choice between specifying the style explicitly +% by \LaTeX\ commands or implicitly by other style keys. But, you're right, +% some implicitly defined styles have no seperate keys, for example the second +% order keyword style. Here---and never with the number 1---you just append +% the order to the base key: \texttt{keywordstyle2}. +% +% You ask for an application? Here you are: one can define different printing +% styles for `subtypes' of a comment, for example +%\ifcolor +% \begin{lstxsample} +% \lstset{morecomment=[s][\color{blue}]{/*+}{*/}, +% morecomment=[s][\color{red}]{/*-}{*/}} +% \end{lstxsample} +%\else +% \begin{lstxsample} +% \lstset{morecomment=[s][\upshape]{/*+}{*/}, +% morecomment=[s][\bfseries]{/*-}{*/}} +% \end{lstxsample} +%\fi +% \begin{lstsample}{\lstset{morecomment=[s]{/*}{*/}}}{} +% \begin{lstlisting} +% /* normal comment */ +% /*+ keep cool */ +% /*- danger! */ +% \end{lstlisting} +% \end{lstsample} +% Here, the comment style is not applied to the second and third line. +% \begin{advise} +% \item Please remember that both `extra' comments must be defined \emph{after} +% the normal comment, since the delimiter `\texttt{/*}' is a substring of +% `\texttt{/*+}' and `\texttt{/*-}'. +% +% \item I have another question. Is `\texttt{language=}\meta{different +% language}' the only way to remove such additional delimiters? +% \advisespace +% Call {\rstyle\ikeyname{deletecomment}} and/or +% {\rstyle\ikeyname{deletestring}} with the same arguments to remove +% the delimiters (but you don't need to provide the optional style +% argument). +% \end{advise} +% Eventually, you might want to use the prefix \texttt{i} on any comment type. +% Then the comment is not only invisible, it is completely discarded from the +% output! +% \begin{lstxsample}[is] +% \lstset{morecomment=[is]{/*}{*/}} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% begin /* comment */ end +% begin/* comment */end +% \end{lstlisting} +% \end{lstsample} +% +% Okay, and now for the real challenges. More general delimiters can be defined +% by the key {\rstyle\ikeyname{moredelim}}. Legal types are {\rstyle\texttt{l}} +% and {\rstyle\texttt{s}}. These types can be preceded by an \texttt{i}, but +% this time \emph{only the delimiters} are discarded from the output. This way +% you can select styles by markers. +% \begin{lstxsample} +% \lstset{moredelim=[is][\ttfamily]{|}{|}} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% roman |typewriter| +% \end{lstlisting} +% \end{lstsample} +% You can even let the package detect keywords, comments, strings, and other +% delimiters inside the contents. +% \begin{lstxsample} +% \lstset{moredelim=*[s][\itshape]{/*}{*/}} +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% /* begin +% (* comment *) +% ' string ' */ +% \end{lstlisting} +% \end{lstsample} +% Moreover, you can force the styles to be applied cumulatively. +% \begin{lstxsample} +% \lstset{moredelim=**[is][\ttfamily]{|}{|}, % cumulative +% moredelim=*[s][\itshape]{/*}{*/}} % not so +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting} +% /* begin +% ' string ' +% |typewriter| */ +% +% | begin +% ' string ' +% /*typewriter*/ | +% \end{lstlisting} +% \end{lstsample} +% Look carefully at the output and note the differences. The second +% \texttt{begin} is not printed in bold typewriter type since standard +% \LaTeX\ has no such font. +% +% This suffices for an introduction. Now go and find some more applications. +% +% +% \subsection{Closing and credits}\label{uClosingAndCredits} +% +% You've seen a lot of keys but you are far away from knowing all of them. +% The next step is the real use of the \packagename{listings} package. +% Please take the following advice. Firstly, look up the known commands and +% keys in the reference guide to get a notion of the notation there. Secondly, +% poke around with these keys to learn some other parameters. Then, hopefully, +% you'll be prepared if you encounter any problems or need some special things. +% +% \begin{advise} +% \item +% There is one question `you' haven't asked all the last pages: who is to +% blame.

email. +% \end{advise} +% +% +% \part{Reference guide} +% +% +% \section{Main reference}\label{rMainReference} +% +% Your first training is completed. Now that you've left the User's guide, the +% friend telling you what to do has gone. Get more practice and become a +% journeyman!^^A :-) +% \begin{advise} +% \item Actually, the friend hasn't gone. There are still some advices, but +% only from time to time. +% \end{advise} +% +% +% \subsection{How to read the reference} +% +% Commands, keys and environments are presented as follows. +% \begin{syntax} +% \item[1.0,default,hints] \texttt{command}, \texttt{environment} or +% \keyname{key} with \meta{parameters} +% +% This field contains the explanation; here we describe the other fields. +% +% If present, the label in the left margin provides extra information: +% `\textit{addon}' indicates additionally introduced functionality, +% `\textit{changed}' a modified key, `\textit{data}' a command just +% containing data (which is therefore adjustable via |\renewcommand|), +% and so on. Some keys and functionality are `\emph{bug}'-marked or +% with a \dag-sign. These features might change in future or could be +% removed, so use them with care. +% +% If there is verbatim text touching the right margin, it is the +% predefined value. Note that some keys default to this value every +% listing, namely the keys which can be used on individual listings only. +% \end{syntax} +% Regarding the parameters, please keep in mind the following: +% \begin{enumerate} +% \item A list always means a comma separated list. You must put braces around +% such a list. Otherwise you'll get in trouble with the +% \packagename{keyval} package; it complains about an undefined key. +% \item You must put parameter braces around the whole value of a key if you +% use an \oarg{optional argument} of a key inside an optional +% \oarg{key=value list}: +% |\begin{lstlisting}[caption=|{\rstyle|{|}|[one]two|{\rstyle|}|}|]|. +% \item Brackets `|[ ]|' usually enclose optional arguments and must be typed +% in verbatim. Normal brackets `[ ]' always indicate an optional argument +% and must not be typed in. Thus |[*]| must be typed in exactly as is, +% but [|*|] just gets |*| if you use this argument. +% \item A vertical rule indicates an alternative, e.g.~^^A +% \meta{\alternative{true,false}} allows either \texttt{true} or +% \texttt{false} as arguments. +% \item If you want to enter one of the special characters |{}#%\|, this +% character must be escaped with a backslash. This means that you must +% write |\}| for the single character `right brace'---but of course not +% for the closing paramater character. +% \end{enumerate} +% +% +% \subsection{Typesetting listings}\label{rTypesettingListings} +% +% \begin{syntax} +% \item[0.19] \rcmdname\lstset\marg{key=value list} +% +% sets the values of the specified keys, see also section +% \ref{uTheKey=ValueInterface}. +% The parameters keep their values up to the end of the current group. +% In contrast, all optional \meta{key=value list}s below modify the +% parameters for single listings only. +% +% \item[0.18] \rcmdname\lstinline\oarg{key=value list}\meta{character}\meta{source code}\meta{same character} +% +% works like |\verb| but respects the active language and style. These +% listings use flexible columns unless requested differently in the +% optional argument, and do not support frames or background colors. +% You can write `|\lstinline!var i:integer;!|' and get +% `\lstinline!var i:integer;!'. +% +% Since the command first looks ahead for an optional argument, you must +% provide at least an empty one if you want to use |[| as +% \meta{character}. +% +% \dag\ An experimental implementation has been done to support the +% syntax |\lstinline|\oarg{key=value list}\marg{source code}. Try it if +% you want and report success and failure. A known limitation is that +% inside another argument the last source code token must not be an +% explicit space token---and, of course, using a listing inside another +% argument is itself experimental, see section \ref{rListingsInsideArguments}. +% +% See also section \ref{rShortInline} for commands to create short analogs +% for the |\lstinline| command. +% +% \item[0.15] |\begin{|\texttt{\rstyle lstlisting}|}|\oarg{key=value list} +% +% \leavevmode\hspace*{-\leftmargini}|\end{|\texttt{\rstyle lstlisting}|}| +% +% typesets the code in between as a displayed listing. +% +% In contrast to the environment of the \packagename{verbatim} package, +% \LaTeX\ code on the same line and after the end of environment is +% typeset respectively executed. +% +% \item[0.1] \rcmdname\lstinputlisting\oarg{key=value list}\marg{file name} +% +% typesets the stand alone source code file as a displayed listing. +% \end{syntax} +% +% +% \subsection{Space and placement} +% +% \begin{syntax} +% \item[0.20,floatplacement] \rkeyname{float}|=|[|*|]\meta{subset of \textup{\texttt{tbph}}}\syntaxor\rkeyname{float} +% +% makes sense on individual displayed listings only and lets them float. +% The argument controls where \LaTeX\ is \emph{allowed} to put the float: +% at the top or bottom of the current/next page, on a separate page, or +% here where the listing is. +% +% The optional star can be used to get a double-column float in a +% two-column document. +% +% \item[0.21,tbp] \rkeyname{floatplacement}|=|\meta{place specifiers} +% +% is used as place specifier if \keyname{float} is used without value. +% +% \item[0.21,\medskipamount] \rkeyname{aboveskip}|=|\meta{dimension} +% \item[0.21,\medskipamount] \rkeyname{belowskip}|=|\meta{dimension} +% +% define the space above and below displayed listings. +% +% \item[0.17,0pt,\dag] \rkeyname{lineskip}|=|\meta{dimension} +% +% specifies additional space between lines in listings. +% +% \item[0.18,c,\dag] \rkeyname{boxpos}|=|\meta{\alternative{b,c,t}} +% +% Sometimes the \packagename{listings} package puts a |\hbox| around a +% listing---or it couldn't be printed or even processed correctly. +% The key determines the vertical alignment to the surrounding material: +% bottom baseline, centered or top baseline. +% \end{syntax} +% +% +% \subsection{The printed range} +% +% \begin{syntax} +% \item[0.12,true] \rkeyname{print}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{print} +% +% controls whether an individual displayed listing is typeset. Even if +% set false, the respective caption is printed and the label is defined. +% +% Note: If the package is loaded without the \texttt{draft} option, you +% can use this key together with |\lstset|. In the other case the key +% can be used to typeset particular listings despite using the +% \texttt{draft} option. +% +% \item[0.1,1] \rkeyname{firstline}|=|\meta{number} +% \item[0.1,9999999] \rkeyname{lastline}|=|\meta{number} +% +% can be used on individual listings only. They determine the physical +% input lines used to print displayed listings. +% +% \item[1.2] \rkeyname{linerange}|={|\meta{first1}\texttt-\meta{last1}\texttt,\meta{first2}\texttt-\meta{last2}\texttt, and so on|}|\label{uoption:linerange} +% +% can be used on individual listings only. The given line ranges +% of the listing are displayed. The intervals must be sorted and must +% not intersect. +% +% \item[0.20,false] \rkeyname{showlines}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{showlines} +% +% If true, the package prints empty lines at the end of listings. +% Otherwise these lines are dropped (but they count for line numbering). +% +% \item[1.0] \rkeyname{emptylines}|=|[|*|]\meta{number} +% +% sets the maximum of empty lines allowed. If there is a block of more +% than \meta{number} empty lines, only \meta{number} ones are printed. +% Without the optional star, line numbers can be disturbed when blank +% lines are omitted; with the star, the lines keep their original +% numbers. +% +% \item[0.19,0] \rkeyname{gobble}|=|\meta{number} +% +% gobbles \meta{number} characters at the beginning of each +% \emph{environment} code line. This key has no effect on \cs{lstinline} +% or \cs{lstinputlisting}. +% +% Tabulators expand to \ikeyname{tabsize} spaces before they are gobbled. +% Code lines with fewer than \ikeyname{gobble} characters are considered +% empty. Never indent the end of environment by more characters. +% \end{syntax} +% +% +% \subsection{Languages and styles}\label{rLanguagesAndStyles} +% +% Please note that the arguments \meta{language}, \meta{dialect}, and +% \meta{style name} are case insensitive and that spaces have no effect. +% \begin{syntax} +% \item[0.18,{{}}] \rkeyname{style}|=|\meta{style name} +% +% activates the key=value list stored with |\lstdefinestyle|. +% +% \item[0.19] \rcmdname\lstdefinestyle\marg{style name}\marg{key=value list} +% +% stores the key=value list. +% +% \item[0.17,{{}}] \rkeyname{language}|=|\oarg{dialect}\meta{language} +% +% activates a (dialect of a) programming language. The `empty' default +% language detects no keywords, no comments, no strings, and so on; it +% may be useful for typesetting plain text. +% If \meta{dialect} is not specified, the package chooses the default +% dialect, or the empty dialect if there is no default dialect. +% +% Table \ref{uPredefinedLanguages} on page \pageref{uPredefinedLanguages} +% lists all languages and dialects provided by \texttt{lstdrvrs.dtx}. +% The predefined default dialects are underlined. +% +% \item[0.21] \rkeyname{alsolanguage}|=|\oarg{dialect}\meta{language} +% +% activates a (dialect of a) programming language in addition to the +% current active one. Note that some language definitions interfere with +% each other and are plainly incompatible; for instance, if one is case +% sensitive and the other is not. +% +% Take a look at the \ikeyname{classoffset} key in section +% \ref{rFigureOutTheAppearance} if you want to highlight the keywords +% of the languages differently. +% +% \item[0.19] \rkeyname{defaultdialect}|=|\oarg{dialect}\meta{language} +% +% defines \meta{dialect} as default dialect for \meta{language}. +% If you have defined a default dialect other than empty, for example +% |defaultdialect=[iama]fool|, you can't select the empty dialect, even +% not with |language=[]fool|. +% \end{syntax} +% +% Finally, here's a small list of language-specific keys. +% \begin{syntax} +% \item[0.19,false,optional] \rkeyname{printpod}|=|\meta{\alternative{true,false}} +% +% prints or drops PODs in Perl. +% +% \item[0.20,true,{renamed,optional}] \rkeyname{usekeywordsintag}|=|\meta{\alternative{true,false}}\label{uoption:usekeywordsintag} +% +% The package either use the first order keywords in tags or prints all +% identifiers inside |<>| in keyword style. +% +% \item[1.1,{{}},optional] \rkeyname{tagstyle}|=|\meta{style}\label{uoption:tagstyle} +% +% determines the style in which tags and their content is printed. +% +% \item[1.1,false,optional] \rkeyname{markfirstintag}|=|\meta{style}\label{uoption:markfirstintag} +% +% prints the first name in tags with keyword style. +% +% \item[0.20,true,optional] \rkeyname{makemacrouse}|=|\meta{\alternative{true,false}} +% +% Make specific: Macro use of identifiers, which are defined as first +% order keywords, also prints the surrounding |$(| and |)| in keyword +% style. e.g.~you could get +% \textbf{\textdollar(}\textbf{strip} \textdollar(BIBS)\textbf{)}. +% If deactivated you get +% \textdollar(\textbf{strip} \textdollar(BIBS)). +% \end{syntax} +% +% +% \subsection{Figure out the appearance}\label{rFigureOutTheAppearance} +% +% \begin{syntax} +% \item[0.18,{{}}] \rkeyname{basicstyle}|=|\meta{basic style} +% +% is selected at the beginning of each listing. You could use +% |\footnotesize|, |\small|, |\itshape|, |\ttfamily|, or something like +% that. The last token of \meta{basic style} must not read any following +% characters. +% +% \item[0.18,{{}}] \rkeyname{identifierstyle}|=|\meta{style} +% \item[0.11,\itshape] \rkeyname{commentstyle}|=|\meta{style} +% \item[0.12,{{}}] \rkeyname{stringstyle}|=|\meta{style} +% +% determines the style for non-keywords, comments, and strings. The +% \emph{last} token can be an one-parameter command like |\textbf| or +% |\underbar|. +% +% \item[0.11,\bfseries,addon] \rkeyname{keywordstyle}|=|\oarg{number}[\textasteriskcentered]\meta{style}\label{roption:keywordstyle} +% +% is used to print keywords. The optional \meta{number} argument is the +% class number to which the style should be applied. +% +% Add-on: If you use the optional star after the (optional) class number, the +% keywords are printed uppercase\,---\,even if a language is case +% sensitive and defines lowercase keywords only. Maybe there should also be an +% option for lowercase keywords \ldots +% +% \item[0.19,keywordstyle,deprecated] \rkeyname{ndkeywordstyle}|=|\meta{style} +% +% is equivalent to |keywordstyle=2|\meta{style}. +% +% \item[1.0,0] \rkeyname{classoffset}|=|\meta{number} +% +% is added to all class numbers before the styles, keywords, identifiers, +% etc.~are assigned. The example below defines the keywords directly; +% you could do it indirectly by selecting two different languages. +% \end{syntax} +%\ifcolor +% \begin{lstxsample} +% \lstset{classoffset=0, +% morekeywords={one,three,five},keywordstyle=\color{red}, +% classoffset=1, +% morekeywords={two,four,six},keywordstyle=\color{blue}, +% classoffset=0}% restore default +% \end{lstxsample} +%\else +% \begin{lstxsample} +% \lstset{classoffset=0, +% morekeywords={one,three,five},keywordstyle=\itshape, +% classoffset=1, +% morekeywords={two,four,six},keywordstyle=\bfseries}, +% classoffset=0}% restore default +% \end{lstxsample} +%\fi +% \begin{lstsample}{}{} +% \begin{lstlisting} +% one two three +% four five six +% \end{lstlisting} +% \end{lstsample} +% +% \begin{syntax} +% \item[0.20,keywordstyle,{addon,bug,optional}] \rkeyname{texcsstyle}|=|[|*|]\oarg{class number}\meta{style}\label{roption:texcsstyle} +% \item[0.20,keywordstyle,optional] \rkeyname{directivestyle}|=|\meta{style} +% +% determine the style of \TeX\ control sequences and directives. +% Note that these keys are present only if you've chosen an appropriate +% language. +% +% The optional star of |texcsstyle| also highlights the backslash in +% front of the control sequence name. Note that this option is set for +% all |texcs| lists. +% +% Bug: \texttt{texcs\ldots} interferes with other keyword lists. If, for +% example, \texttt{emph} contains the word \texttt{foo}, then the control +% sequence |\foo| will show up in \texttt{emphstyle}. +% +% \item[0.21] \rkeyname{emph}|=|\oarg{number}\marg{identifier list} +% \item[0.21] \rkeyname{moreemph}|=|\oarg{number}\marg{identifier list} +% \item[0.21] \rkeyname{deleteemph}|=|\oarg{number}\marg{identifier list} +% \item[0.21] \rkeyname{emphstyle}|=|\oarg{number}\marg{style} +% +% respectively define, add or remove the \meta{identifier list} from +% `emphasize class \meta{number}', or define the style for that class. +% If you don't give an optional argument, the package assumes +% \meta{number}$\,=1$. +% +% These keys are described more detailed in section +% \ref{uEmphasizeIdentifiers}. +% +% \item[1.0] \rkeyname{delim}|=|[\texttt*[\texttt*]]\texttt[\meta{type}\texttt][\texttt[\meta{style}\texttt]]\meta{delimiter\textup(s\textup)} +% \item[1.0] \rkeyname{moredelim}|=|[\texttt*[\texttt*]]\texttt[\meta{type}\texttt][\texttt[\meta{style}\texttt]]\meta{delimiter\textup(s\textup)} +% \item[1.0] \rkeyname{deletedelim}|=|[\texttt*[\texttt*]]\texttt[\meta{type}\texttt]\meta{delimiter\textup(s\textup)} +% +% define, add, or remove user supplied delimiters. (Note that this does +% not affect strings or comments.) +% +% In the first two cases \meta{style} is used to print the delimited +% code (and the delimiters). Here, \meta{style} could be something like +% |\bfseries| or |\itshape|, or it could refer to other styles via +% \texttt{keywordstyle}, \texttt{keywordstyle2}, \texttt{emphstyle}, +% etc. +% +% Supported types are \texttt{l} and \texttt{s}, see the comment keys in +% section \ref{uLanguageDefinitions} for an explanation. If you use the +% prefix \texttt i, i.e.~\texttt{il} or \texttt{is}, the delimiters are +% not printed, which is some kind of invisibility. +% +% If you use one optional star, the package will detect keywords, +% comments, and strings inside the delimited code. With both optional +% stars, aditionally the style is applied cumulatively; see section +% \ref{uDelimiters}. +% \end{syntax} +% +% +% \subsection{Getting all characters right} +% +% \begin{syntax} +% \item[0.18,true] \rkeyname{extendedchars}|=|\meta{\alternative{true,false}}\syntaxor\rkeyname{extendedchars} +% +% allows or prohibits extended characters in listings, that means +% (national) characters of codes 128--255. If you use extended +% characters, you should load \packagename{fontenc} and/or +% \packagename{inputenc}, for example. +% +% \item[1.0,{{}}] \rkeyname{inputencoding}|=|\meta{encoding} +% +% determines the input encoding. The usage of this key requires the +% \packagename{inputenc} package; nothing happens if it's not loaded. +% +% \item[1.1,false] \rkeyname{upquote}|=|\meta{\alternative{true,false}}\label{uoption:upquote} +% +% determines whether the left and right quote are printed |`'| or +% \texttt{\textasciigrave\textquotesingle}. +% This key requires the \packagename{textcomp} package if true. +% +% \item[0.12,8] \rkeyname{tabsize}|=|\meta{number} +% +% sets tabulator stops at columns $\meta{number}+1$, $2\cdot\meta{number}+1$, $3\cdot\meta{number}+1$, and so on. +% Each tabulator in a listing moves the current column to the next +% tabulator stop. +% +% \item[0.20,false] \rkeyname{showtabs}|=|\meta{\alternative{true,false}} +% +% make tabulators visible or invisible. A visible tabulator looks like +% \lstinline[showtabs]! !, but that can be changed. If you choose +% invisible tabulators but visible spaces, tabulators are converted to +% an appropriate number of spaces. +% +% \item[0.20] \rkeyname{tab}|=|\meta{tokens} +% +% \meta{tokens} is used to print a visible tabulator. You might want to use |$\to$|, |$\mapsto$|, |$\dashv$| or something like that instead of the strange default definition. +% +% \item[0.20,false] \rkeyname{showspaces}|=|\meta{\alternative{true,false}} +% +% lets all blank spaces appear {\textvisiblespace} or as blank spaces. +% +% \item[0.12,true] \rkeyname{showstringspaces}|=|\meta{\alternative{true,false}} +% +% lets blank spaces in strings appear {\textvisiblespace} or as blank +% spaces. +% +% \item[0.19,\bigbreak] \rkeyname{formfeed}|=|\meta{tokens} +% +% Whenever a listing contains a form feed, \meta{tokens} is executed. +% \end{syntax} +% +% +% \subsection{Line numbers}\label{rLineNumbers} +% +% \begin{syntax} +% \item[1.0,none] \rkeyname{numbers}|=|\meta{\alternative{none,left,right}} +% +% makes the package either print no line numbers, or put them on the +% left or the right side of a listing. +% +% \item[0.16,1] \rkeyname{stepnumber}|=|\meta{number} +% +% All lines with ``line number $\equiv 0$ modulo \meta{number}'' get a +% line number. +% If you turn line numbers on and off with \keyname{numbers}, the +% parameter \keyname{stepnumber} will keep its value. Alternatively you +% can turn them off via |stepnumber=0| and on with a nonzero number, and +% keep the value of \keyname{numbers}. +% +% \item[1.1,false] \rkeyname{numberfirstline}|=|\meta{\alternative{true,false}}\label{uoption:numberfirstline} +% +% The first line of each listing gets numbered (if numbers are on at all) +% even if the line number is not divisible by \keyname{stepnumber}. +% +% \item[0.16,{{}}] \rkeyname{numberstyle}|=|\meta{style} +% +% determines the font and size of the numbers. +% +% \item[0.19,10pt] \rkeyname{numbersep}|=|\meta{dimension} +% +% is the distance between number and listing. +% +% \item[1.0,true] \rkeyname{numberblanklines}|=|\meta{\alternative{true,false}} +% +% If this is set to false, blank lines get no printed line number. +% +% \item[0.20,auto] \rkeyname{firstnumber}|=|\meta{\alternative{auto,last,\normalfont\meta{number}}} +% +% \texttt{auto} lets the package choose the first number: a new listing +% starts with number one, a named listing continues the most recent +% same-named listing (see below), and a stand alone file begins with +% the number corresponding to the first input line. +% +% \texttt{last} continues the numbering of the most recent listing and +% \meta{number} sets it to the number. +% +% \item[1.0] \rkeyname{name}|=|\meta{name} +% +% names a listing.

Starting and ending delimiters are the same, i.e.~in the +% source code the delimiters must match each other. +% +% The optional argument is the type and controls the how the delimiter +% itself is represented in a string or character literal: it is escaped by a +% |b|ackslash, |d|oubled (or both is allowed via |bd|). Alternately, the +% type can refer to an unusual form of delimiter: |s|tring delimiters (akin +% to the |s| comment type) or |m|atlab-style delimiters. The latter is a +% special type for Ada and Matlab and possibly other languages where the +% string delimiters are also used for other purposes.

The following overview uses \keyname{morecomment} as the +% example, but the examples apply to \keyname{comment} and \keyname{deletecomment} +% as well. +% +% \item[0.13] \keyname{morecomment}|=[l]|\meta{delimiter} +% +% The delimiter starts a comment line, which in general starts with the +% delimiter and ends at end of line. If the character sequence |//| +% should start a comment line (like in \Cpp, Comal 80 or Java), +% |morecomment=[l]//| is the correct declaration.

A semicolon always ends such a +% comment. Any keyword of the first argument begins a comment and any +% keyword of the second argument ends it (and a semicolon also); +% a comment starting with any keyword of the third argument is terminated +% with the next semicolon only. In the example all possible comments are +% `\textbf{end}\ldots\textbf{else}', `\textbf{end}\ldots\textbf{end}' +% (does not start a comment again) and `\textbf{comment}\ldots;' and +% `\textbf{end}\ldots;'. +% Maybe a curious definition, but Algol and Simula use such comments. +% +% Note: The keywords here need not to be a subset of the defined +% keywords.

Each new installation or new version overwrites +% it. The software license allows modification, but I can't recommend it. +% It's better to create one or more of the files +% \begin{center} +% \begin{tabular}{lcl} +% \texttt{lstmisc0.sty} & for & local add-ons +% (see the developer's guide),\\ +% \texttt{lstlang0.sty} & for & local language definitions +% (see \ref{rLanguageDefinitions}), and\\ +% \texttt{lstlocal.cfg} & as & local configuration file +% \end{tabular} +% \end{center} +% and put them in the same directory as the other \packagename{listings} files. +% These three files are not touched by a new installation unless you remove them. +% If \texttt{lstlocal.cfg} exists, it is loaded after \texttt{listings.cfg}. +% You might want to change one of the following parameters. +% \begin{syntax} +% \item[,,data] \rcmdname\lstaspectfiles\quad contains~\rlap{\texttt{\lstaspectfiles}} +% \item[,,data] \rcmdname\lstlanguagefiles\quad contains~\rlap{\texttt{\lstlanguagefiles}} +% +% The package uses the specified files to find add-ons and language +% definitions. +% \end{syntax} +% Moreover, you might want to adjust +% \icmdname\lstlistlistingname, +% \icmdname\lstlistingname, +% \ikeyname{defaultdialect}, +% \icmdname\lstalias, or +% \icmdname\lstalias +% \ as described in earlier sections. +% +% +% \section{Experimental features}\label{rExperimentalFeatures} +% +% This section describes the more or less unestablished parts of this package. +% It's unlikely that they will all be removed (unless stated explicitly), but +% they are liable to (heavy) changes and improvements. Such features have been +% \dag-marked in the last sections. So, if you find anything \dag-marked here, +% you should be very, very careful. +% +% +% \subsection{Listings inside arguments}\label{rListingsInsideArguments} +% +% There are some things to consider if you want to use |\lstinline| or the +% listing environment inside arguments. Since \TeX\ reads the argument before +% the `\lst-macro' is executed, this package can't do anything to preserve the +% input: spaces shrink to one space, the tabulator and the end of line are +% converted to spaces, \TeX's comment character is not printable, and so on. +% Hence, \emph{you} must work a bit more. You have to put a backslash in front +% of each of the following four characters: |\{}%|. Moreover you must protect +% spaces in the same manner if: (i) there are two or more spaces following each +% other or (ii) the space is the first character in the line. +% That's not enough: Each line must be terminated with a `line feed' |^^J|. +% And you can't escape to \LaTeX\ inside such listings! +% +% The easiest examples are with |\lstinline| since we need no line feed. +% \begin{verbatim} +%\footnote{\lstinline{var i:integer;} and +% \lstinline!protected\ \ spaces! and +% \fbox{\lstinline!\\\{\}\%!}}\end{verbatim} +% yields\lstset{language=Pascal}\footnote{\lstinline{var i:integer;} and +% \lstinline!protected\ \ spaces! and +% \fbox{\lstinline!\\\{\}\%!}} +% if the current language is Pascal. Note that this example shows another +% experimental feature: use of argument braces as delimiters. This is +% described in section \ref{rTypesettingListings}. +% +% And now an environment example: +% \begin{lstsample}{\lstset{language={}}}{} +% \fbox{% +% \begin{lstlisting}^^J +% \ !"#$\%&'()*+,-./^^J +% 0123456789:;<=>?^^J +% @ABCDEFGHIJKLMNO^^J +% PQRSTUVWXYZ[\\]^_^^J +% `abcdefghijklmno^^J +% pqrstuvwxyz\{|\}~^^J +% \end{lstlisting}} +% \end{lstsample} +% \begin{advise} +% \item You might wonder that this feature is still experimental. The reason: +% You shouldn't use listings inside arguments; it's not always safe. +% \end{advise} +% +% +% \subsection{\dag\ Export of identifiers}\label{rExportOfIdentifiers} +% +% It would be nice to export function or procedure names. In general that's a +% dream so far. The problem is that programming languages use various syntaxes +% for function and procedure declaration or definition. A general interface is +% completely out of the scope of this package---that's the work of a compiler +% and not of a pretty-printing tool. However, it is possible for particular +% languages: in Pascal, for instance, each function or procedure definition and +% variable declaration is preceded by a particular keyword. +% Note that you must request the following keys with the \texttt{procnames} option: +% |\usepackage[procnames]{listings}|. +% \begin{syntax} +% \item[0.19,{{}},{\dag optional}] \rkeyname{procnamekeys}|=|\marg{keywords} +% \item[0.21,,\dag optional] \rkeyname{moreprocnamekeys}|=|\marg{keywords} +% \item[0.21,,\dag optional] \rkeyname{deleteprocnamekeys}|=|\marg{keywords} +% +% each specified keyword indicates a function or procedure definition. +% Any identifier following such a keyword appears in `procname' style. +% For Pascal you might use\vspace{-.5\baselineskip} +% \begin{verbatim} +% procnamekeys={program,procedure,function}\end{verbatim} +% +% \item[0.19,keywordstyle,\dag optional] \rkeyname{procnamestyle}|=|\meta{style} +% +% defines the style in which procedure and function names appear. +% +% \item[0.19,false,\dag optional] \rkeyname{indexprocnames}|=|\meta{\alternative{true,false}} +% +% If activated, procedure and function names are also indexed. +% \end{syntax} +% \begin{TODO} +% The \aspectname{procnames} aspect is unsatisfactory (and has been unchanged +% at least since 2000). It marks and indexes the function definitions so far, but +% it would be possible to mark also the following function calls, for example. +% A key could control whether function names are added to a special keyword +% class, which then appears in `procname' style. But should these names be +% added globally? There are good reasons for both. Of course, we would also +% need a key to reset the name list. +% \end{TODO} +% +% +% \subsection{\dag\ Hyperlink references}\label{rHyperReferences} +% +% This very small aspect must be requested via the \texttt{hyper} option since it +% is experimental. One possibility for the future is to combine this aspect +% with \aspectname{procnames}. Then it should be possible to click on a +% function name and jump to its definition, for example. +% \begin{syntax} +% \item[0.21,,{\dag optional}] \rkeyname{hyperref}|=|\marg{identifiers} +% \item[0.21,,{\dag optional}] \rkeyname{morehyperref}|=|\marg{identifiers} +% \item[0.21,,{\dag optional}] \rkeyname{deletehyperref}|=|\marg{identifiers} +% +% hyperlink the specified identifiers (via \packagename{hyperref} +% package). A `click' on such an identifier jumps to the previous +% occurrence. +% +% \item[0.21,\hyper@@anchor,{\dag optional}] \rkeyname{hyperanchor}|=|\meta{two-parameter macro} +% \item[0.21,\hyperlink,{\dag optional}] \rkeyname{hyperlink}|=|\meta{two-parameter macro} +% +% set a hyperlink anchor and link, respectively. +% The defaults are suited for the \packagename{hyperref} package. +% \end{syntax} +% +% +% \subsection{Literate programming} +% +% We begin with an example and hide the crucial key=value list. +% \begin{lstsample}{\lstset{literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1}}{} +% \begin{lstlisting} +% var i:integer; +% +% if (i<=0) i := 1; +% if (i>=0) i := 0; +% if (i<>0) i := 0; +% \end{lstlisting} +% \end{lstsample} +% Funny, isn't it? We could leave |i := 0| in our listings instead of +% i| |$\gets$| |0, but that's not literate! ^^A :-) +% Now you might want to know how this has been done. Have a \emph{close} +% look at the following key. +% \begin{syntax} +% \item[0.20,,\dag] \rkeyname{literate}|=|[|*|]\meta{replacement item}\ldots\meta{replacement item} +% +% First note that there are no commas between the items. Each item +% consists of three arguments: +% \marg{replace}\marg{replacement text}\marg{length}. +% \meta{replace} is the original character sequence. +% Instead of printing these characters, we use \meta{replacement text}, +% which takes the width of \meta{length} characters in the output. +% +% Each `printing unit' in \meta{replacement text} \emph{must} be in braces +% unless it's a single character. For example, you must put braces +% around |$\leq$|. +% If you want to replace |<-1->| by |$\leftarrow1\rightarrow$|, the +% replacement item would be |{<-1->}{{$\leftarrow$}1{$\rightarrow$}}3|. +% Note the braces around the arrows. +% +% If one \meta{replace} is a subsequence of another \meta{replace}, you +% must define the shorter sequence first. For example, |{-}| must be defined +% before |{--}| and this before |{-->}|. +% +% The optional star indicates that literate replacements should not be +% made in strings, comments, and other delimited text. +% \end{syntax} +% In the example above, I've used +% \begin{verbatim} +% literate={:=}{{$\gets$}}1 {<=}{{$\leq$}}1 {>=}{{$\geq$}}1 {<>}{{$\neq$}}1\end{verbatim} +% \begin{TODO} +% Of course, it's good to have keys for adding and removing single +% \meta{replacement item}s. Maybe the key(s) should work in the same fashion +% as the string and comment definitions, i.e.~one item per key=value. +% This way it would be easier to provide better auto-detection in case of a +% subsequence. +% \end{TODO} +% +% +% \subsection{\textsf{LGrind} definitions}\label{rLGrindDefinitions} +% +% Yes, it's a nasty idea to steal language definitions from other programs. +% Nevertheless, it's possible for the \packagename{LGrind} definition +% file---at least partially. Please note that this file must be found by +% \TeX. +% \begin{syntax} +% \item[0.21,,{optional}] \rkeyname{lgrindef}|=|\meta{language} +% +% scans the \texttt{lgrindef} language definition file for +% \meta{language} and activates it if present. Note that not all +% \packagename{LGrind} capabilities have a \packagename{listings} +% analogue. +% +% Note that `Linda' language doesn't work properly since it defines +% compiler directives with preceding `|#|' as keywords. +% +% \item[0.21,lgrindef.,{data,optional}] \rcmdname\lstlgrindeffile +% +% contains the (path and) name of the definition file. +% \end{syntax} +% +% +% \subsection{\dag\ Automatic formatting} +% +% \lstloadaspects{formats}^^A +% The automatic source code formatting is far away from being good. First of +% all, there are no general rules on how source code should be formatted. So +% `format definitions' must be flexible. This flexibility requires a complex +% interface, a powerful `format definition' parser, and lots of code lines +% behind the scenes. Currently, format definitions aren't flexible enough +% (possibly not the definitions but the results). A single `format item' has +% the form +% \begin{itemize}\item[] +% \meta{input chars}|=|\oarg{exceptional chars}\meta{pre}\oarg{\texttt{\string\string}}\meta{post} +% \end{itemize} +% Whenever \meta{input chars} aren't followed by one of the \meta{exceptional +% chars}, formatting is done according to the rest of the value. If |\string| +% isn't specified, the input characters aren't printed (except it's an +% identifier or keyword). Otherwise \meta{pre} is `executed' before printing +% the original character string and \meta{post} afterwards. These two are +% `subsets' of +% \begin{itemize} +% \item |\newline| ---ensuring a new line; +% \item |\space| ---ensuring a whitespace; +% \item |\indent| ---increasing indention; +% \item |\noindent| ---descreasing indention. +% \end{itemize} +% Now we can give an example.\lstaspectindex{\lstdefineformat}{}\lstaspectindex{format}{} +% \begin{lstxsample} +% \lstdefineformat{C}{% +% \{=\newline\string\newline\indent,% +% \}=\newline\noindent\string\newline,% +% ;=[\ ]\string\space} +% \end{lstxsample} +% \begin{lstsample}{\lstset{language={}}}{} +% \begin{lstlisting}[format=C] +% for (int i=0;i<10; i++){/* wait */}; +% \end{lstlisting} +% \end{lstsample} +% Not good. But there is a (too?) simple work-around: +% \begin{lstxsample} +% \lstdefineformat{C}{% +% \{=\newline\string\newline\indent,% +% \}=[;]\newline\noindent\string\newline,% +% \};=\newline\noindent\string\newline,% +% ;=[\ ]\string\space} +% \end{lstxsample} +% \begin{lstsample}{\lstset{language={}}}{} +% \begin{lstlisting}[format=C] +% for (int i=0;i<10; i++){/* wait */}; +% \end{lstlisting} +% \end{lstsample} +% Sometimes the problem is just to find a suitable format definition. +% Further formatting is complicated. +% Here are only three examples with increasing level of difficulty. +% \begin{enumerate} +% \item Insert horizontal space to separate function/procedure name and +% following parenthesis or to separate arguments of a function, +% e.g.~add the space after a comma (if inside function call). +% \item Smart breaking of long lines. Consider long `and/or' expressions. +% Formatting should follow the logical structure! +% \item Context sensitive formatting rules. It can be annoying if empty +% or small blocks take three or more lines in the output---think of +% scrolling down all the time. So it would be nice if the block +% formatting was context sensitive. +% \end{enumerate} +% Note that this is a very first and clumsy attempt to provide automatic +% formatting---clumsy since the problem isn't trivial. Any ideas are welcome. +% Implementations also. Eventually you should know that you must request format +% definitions at package loading, e.g.~via |\usepackage[formats]{listings}|. +% +% \subsection{Arbitrary linerange markers}\label{rArbitraryLinerangeMarkers} +% +% Instead of using \keyname{linerange} with line numbers, one can use text +% markers. Each such marker consists of a \meta{prefix}, a \meta{text}, and a +% \meta{suffix}. You once (or more) define prefixes and suffixes and then use +% the marker text instead of the line numbers. +% \begin{lstxsample} +% \lstset{rangeprefix=\{\ ,% curly left brace plus space +% rangesuffix=\ \}}% space plus curly right brace +% \end{lstxsample} +% \begin{lstsample}{}{} +% \begin{lstlisting}% +% [linerange=loop\ 2-end] +% { loop 1 } +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% { end } +% { loop 2 } +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% { end } +% \end{lstlisting} +% \end{lstsample} +% Note that \TeX's special characters like the curly braces, the space, the +% percent sign, and such must be escaped with a backslash. +% \begin{syntax} +% \item[1.2] \rkeyname{rangebeginprefix}|=|\meta{prefix} +% \item[1.2] \rkeyname{rangebeginsuffix}|=|\meta{suffix} +% \item[1.2] \rkeyname{rangeendprefix}|=|\meta{prefix} +% \item[1.2] \rkeyname{rangeendsuffix}|=|\meta{suffix} +% +% define individual prefixes and suffixes for the begin- and end-marker. +% +% \item[1.2] \rkeyname{rangeprefix}|=|\meta{prefix} +% \item[1.2] \rkeyname{rangesuffix}|=|\meta{suffix} +% +% define identical prefixes and suffixes for the begin- and end-marker. +% +% \item[1.2,true] \rkeyname{includerangemarker}|=|\meta{\alternative{true,false}} +% +% shows or hides the markers in the output. +% \end{syntax} +% \begin{lstsample}{\lstset{rangeprefix=\{\ ,rangesuffix=\ \}}}{} +% \begin{lstlisting}% +% [linerange=loop\ 1-end, +% includerangemarker=false, +% frame=single] +% { loop 1 } +% for i:=maxint to 0 do +% begin +% { do nothing } +% end; +% { end } +% \end{lstlisting} +% \end{lstsample} +% +% +% \subsection{Multicolumn Listings}\label{rMulticolumnListings} +% +% When the \packagename{multicol} package is loaded, it can be used to typeset +% multi-column listings. These are specified with the |multicols| key. For +% example: +% \begin{lstsample}{}{} +% \begin{lstlisting}[multicols=2] +% if (i < 0) +% i = 0 +% j = 1 +% end if +% if (j < 0) +% j = 0 +% end if +% \end{lstlisting} +% \end{lstsample} +% +% The multicolumn option is known to fail with some keys. +% +% \begin{advise} +% \item Which keys? +% \advisespace +% Unfortunately, I don't know. Carsten left the code for this option +% in the version 1.3b patch file with only that cryptic note for +% documentation. Bug reports would be welcome, though I don't promise +% that they're fixable. ---Brooks +% \end{advise} +% +% +%\iffalse +% \section{Forthcoming ?} +% +% This section is rather rudimentary. It just lists some things I don't want +% to forget. +% +% First of all, I'd like to support even more languages, for example Maple, +% PostScript, and so on. Fortunately my lifetime is limited, so other +% people may do that work. Please (e-)mail me your language definitions. +% +% Then, there are several ideas for the future. Some have already been stated +% as `to do's; some came from other people and are stated below; some more are +% far from being implemented, +% e.g.~\keyname{linerange}|=|\oarg{inter}\marg{line range list} +% which prints all lines in the range and executes \meta{inter} when omitting +% some code lines. The main problem here are frames and background colours; +% what should happen to them? In fact, the problem is how this can be coded. +% Another idea is to change the background colour (or the basic style) for +% particular code blocks. This, too, is not easy. +% +%^^A Auto-detect whether surplus space (from spaces and tabs) isn't needed to fix +%^^A alignment of wide character combinations like |==| or |<>|. +%^^A +%^^A Make package compatible to calc package. +%^^A +%^^A Rewrite \lst@LAS, \lst@DefDriver, \lst@Require to distinguish loading +%^^A of languages (which don't need base languages at once) and aspects +%^^A (which need required aspects to be loaded). +% +% \lsthelper{Vincent~Poirriez}{1999/11/18}{code examples inside caml comments}: +% Inside caml comments, |[| and |]| should print the code in +% between in basicstyle (or another newly introduced style).

Some +% people asked for continued captions. +%\fi +% +% +% \part{Tips and tricks} +% +% Note: This part of the documentation is under construction. +% Section \ref{uHowTos} must be sorted by topic and ordered in some way. +% Moreover a new section `Examples' is planned, but not written. +% Lack of time is the main problem \ldots +% +% +% \section{Troubleshooting}\label{uTroubleshooting} +% +% If you're faced with a problem with the \packagename{listings} package, there are +% some steps you should undergo before you make a bug report. First you should +% consult the reference guide to see whether the problem is already known. If not, +% create a \emph{minimal} file which reproduces the problem. Follow these +% instructions: +% \begin{enumerate} +% \item Start from the minimal file in section \ref{uAMinimalFile}. +% \item Add the \LaTeX\ code which causes the problem, but keep it short. +% In particular, keep the number of additional packages small. +% \item Remove some code from the file (and the according packages) until the +% problem disappears. Then you've found a crucial piece. +% \item Add this piece of code again and start over with step 3 until all code +% and all packages are substantial. +% \item You now have a minimal file. Send a bug report to the address on the +% first page of this documentation and include the minimal file together +% with the created \texttt{.log}-file. If you use a very special package +% (i.e.~one not on CTAN), also include the package if its software license +% allows it. +% \end{enumerate} +% +% +% \section{How tos}\label{uHowTos} +% +% +% \subsubsection*{How to reference line numbers} +% Perhaps you want to put |\label{|\meta{whatever}|}| into a \LaTeX\ escape which is +% inside a comment whose delimiters aren't printed? If you did that, the compiler +% won't see the \LaTeX\ code since it would be inside a comment, and the +% \packagename{listings} package wouldn't print anything since the delimiters would +% be dropped and |\label| doesn't produce any printable output, but you could still +% reference the line number. Well, your wish is granted. +% +% In Pascal, for example, you could make the package recognize the `special' +% comment delimiters |(*@| and |@*)| as begin-escape and end-escape sequences. +% Then you can use this special comment for |\label|s and other things. +% \begin{lstsample}{\lstset{numberstyle=\tiny,stepnumber=2,numbersep=5pt}}{} +% \lstset{escapeinside={(*@}{@*)}} +% +% \begin{lstlisting} +% for i:=maxint to 0 do +% begin +% { comment }(*@\label{comment}@*) +% end; +% \end{lstlisting} +% Line \ref{comment} shows a comment. +% \end{lstsample} +% \begin{advise} +% \item Can I use `|(*@|' and `|*)|' instead? +% \advisespace +% Yes. +% \item Can I use `|(*|' and `|*)|' instead? +% \advisespace +% Sure. If you want this. +% \item Can I use `|{@|' and `|@}|' instead? +% \advisespace +% No, never! The second delimiter is not allowed. The character `|@|' is +% defined to check whether the escape is over. But reading the lonely +% `end-argument' brace, \TeX\ encounters the error `\texttt{Argument of @ +% has an extra \char125}'. Sorry. +% \item Can I use `|{|' and `|}|' instead? +% \advisespace +% No. Again the second delimiter is not allowed. Here now \TeX\ would +% give you a `\texttt{Runaway argument}' error. Since `|}|' is defined to +% check whether the escape is over, it won't work as `end-argument' brace. +% \item And how can I use a comment line? +% \advisespace +% For example, write `|escapeinside={//*}{\^^M}|'. Here |\^^M| represents +% the end of line character. +% \end{advise} +% +% +% \subsubsection*{How to gobble characters} +% To make your \LaTeX\ code more readable, you might want to indent your +% \texttt{lstlisting} listings. This indention should not show up in the +% pretty-printed listings, however, so it must be removed. If you indent each code +% line by three characters, you can remove them via |gobble=3|: +% \begin{lstsample}{}{\lstset{showspaces}} +% \begin{lstlisting}[gobble=3] +% 1 for i:=maxint to 0 do +% 2 begin +% 3 { do nothing } +% 123end; +% +% Write('Case insensitive '); +% WritE('Pascal keywords.'); +% \end{lstlisting} +% \end{lstsample} +% Note that empty lines and the beginning and the end of the environment +% need not respect the indention. However, never indent the end by more than +% `\ikeyname{gobble}' characters. Moreover note that tabulators expand to +% |tabsize| spaces before we gobble. +% \begin{advise} +% \item Could I use `\ikeyname{gobble}' together with `|\lstinputlisting|'? +% \advisespace +% Yes, but it has no effect. +% +% \item Note that `\ikeyname{gobble}' can also be set via `|\lstset|'. +% \end{advise} +% +% +% \subsubsection*{How to include graphics} +% \lsthelper{Herbert~Weinhandl}{1999/09/06}{listings + eps} found a very easy +% way to include graphics in listings. Thanks for contributing this idea---an +% idea I would never have had. +% +% Some programming languages allow the dollar sign to be part of an identifier. +% But except for intermediate function names or library functions, this +% character is most often unused. The \packagename{listings} package defines +% the \ikeyname{mathescape} key, which lets `|$|' escape to \TeX's math mode. +% This makes the dollar character an excellent candidate for our purpose here: +% use a package which can include a graphic, set \ikeyname{mathescape} true, +% and include the graphic between two dollar signs, which are inside a comment. +% +% The following example is originally from a header file I got from Herbert. +% For the presentation here I use the \texttt{lstlisting} environment and an +% excerpt from the header file. The |\includegraphics| command is from +% David Carlisle's \packagename{graphics} bundle. +% \begin{verbatim} +% \begin{lstlisting}[mathescape=true] +% /* +% $ \includegraphics[height=1cm]{defs-p1.eps} $ +% */ +% typedef struct { +% Atom_T *V_ptr; /* pointer to Vacancy in grid */ +% Atom_T *x_ptr; /* pointer to (A|B) Atom in grid */ +% } ABV_Pair_T; +% \end{lstlisting}\end{verbatim} +% The result looks pretty good. Unfortunately you can't see it, because the +% graphic wasn't available when the manual was typeset. +% +% +% \subsubsection*{How to get closed frames on each page} +% The package supports closed frames only for listings which don't cross pages. +% If a listing is split on two pages, there is neither a bottom rule at the +% bottom of a page, nor a top rule on the following page. If you insist on +% these rules, you might want to use \texttt{framed.sty} by Donald Arseneau. +% Then you could write +% \begin{verbatim} +% \begin{framed} +% \begin{lstlisting} +% or \lstinputlisting{...} +% \end{lstlisting} +% \end{framed}\end{verbatim} +% The package also provides a \texttt{shaded} environment. If you use it, you +% shouldn't forget to define \texttt{shadecolor} with the \packagename{color} +% package. +% +% +% \subsubsection*{How to print national characters with $\Lambda$ and \packagename{listings}}\label{uNationalCharacters} +% +% Apart from typing in national characters directly, you can use the `escape' +% feature described in section \ref{rEscapingToLaTeX}. +% The keys \ikeyname{escapechar}, \ikeyname{escapeinside}, and \ikeyname{texcl} +% allow partial usage of \LaTeX\ code. +% +% Now, if you use $\Lambda$ (Lambda, the \LaTeX\ variant for Omega) and want, +% for example, Arabic comment lines, you need not write |\begin{arab}| +% \ldots\ |\end{arab}| each escaped comment line. This can be automated: +% \begin{verbatim} +% \lstset{escapebegin=\begin{arab},escapeend=\end{arab}} +% +% \begin{lstlisting}[texcl] +% // Replace text by Arabic comment. +% for (int i=0; i<1; i++) { }; +% \end{lstlisting}\end{verbatim} +% If your programming language doesn't have comment lines, you'll have to use +% \ikeyname{escapechar} or \ikeyname{escapeinside}: +% \begin{verbatim} +% \lstset{escapebegin=\begin{greek},escapeend=\end{greek}} +% +% \begin{lstlisting}[escapeinside=`'] +% /* `Replace text by Greek comment.' */ +% for (int i=0; i<1; i++) { }; +% \end{lstlisting}\end{verbatim} +% Note that the delimiters |`| and |'| are essential here. The example doesn't +% work without them. There is a more clever way if the comment delimiters of +% the programming language are single characters, like the braces in Pascal: +% \begin{verbatim} +% \lstset{escapebegin=\textbraceleft\begin{arab}, +% escapeend=\end{arab}\textbraceright} +% +% \begin{lstlisting}[escapeinside=\{\}] +% for i:=maxint to 0 do +% begin +% { Replace text by Arabic comment. } +% end; +% \end{lstlisting}\end{verbatim} +% Please note that the `interface' to $\Lambda$ is completely untested. +% Reports are welcome! +% +% +% \subsubsection*{How to get bold typewriter type keywords} +% Use the \href{http://www.ctan.org/tex-archive/fonts/luximono}{\packagename{LuxiMono}} package. +% +% \iffalse +% Many people asked for bold typewriter fonts since they aren't included in +% the \LaTeX\ standard distribution. Here now one answer on how to use them +% in spite of that. +% \begin{advise} +% \item Please note that I personally don't regard the following as a good +% solution. Such a bold typewriter type is too heavy. It would be better +% to use a light version of \texttt{cmtt} as basic font and \texttt{cmtt} +% or a \emph{slightly} heavier type for keywords. +% +% \item Why don't you tell us how to use the better solution? +% \advisespace +% A light version of \texttt{cmtt} doesn't exist. If it's once available, +% you can do a similar job as described below. +% \end{advise} +% First of all, you'll need Metafont source files for bold typewriter, e.g.~ +% \texttt{cmbtt8.mf}, \texttt{cmbtt9.mf} and \texttt{cmbtt10.mf} from +% \href{ftp://ftp.dante.de/tex-archive/fonts/cm/mf-extra/bold} +% {CTAN/fonts/cm/mf-extra/bold}. +% Secondly you have to create \texttt{.tfm}-files, i.e.~run the Metafont +% program on these sources. This is possibly done automatically when you use +% the fonts in a document. Finally you must tell \LaTeX\ that you've installed +% bold typewriter fonts. Just use +% \begin{verbatim} +% \DeclareFontShape{OT1}{cmtt}{bx}{n} +% {<5><6><7><8>cmbtt8% +% <9>cmbtt9% +% <10><10.95>cmbtt10% +% <12><14.4><17.28><20.74><24.88>cmbtt10% +% }{}\end{verbatim} +% in the preamble of your document. If you use these fonts often, you might +% want to make a local copy of \texttt{ot1cmtt.fd} and replace the declaration +% there. But note that you're not allowed to distributed the modified file +% under its original name! +% \fi +% +% +% \subsubsection*{How to work with plain text} +% If you want to use \packagename{listings} to set plain text (perhaps with +% line numbers, or like |verbatim| but with line wrapping, or so forth, use +% the empty language: |\lstset{language=}|. +% +% +% \subsubsection*{How to get the developer's guide} +% In the \emph{source directory} of the listings package, i.e.~where +% the \texttt{.dtx} files are, create the file \texttt{ltxdoc.cfg} with the +% following contents. +% \begin{verbatim} +% \AtBeginDocument{\AlsoImplementation}\end{verbatim} +% Then run \texttt{listings.dtx} through \LaTeX\ twice, run Makeindex (with +% the |-s gind.ist| option), and then run \LaTeX\ one last time on +% \texttt{listings.dtx}.

But note that you are in a pretty good shape: +% this developer's guide exists! ^^A :-) +% You might want to peek into section \ref{dPackageExtensions} before reading +% section \ref{dBasicConcepts}. +% +% +% \section{Basic concepts}\label{dBasicConcepts} +% +% The functionality of the \packagename{listings} package appears to be +% divided into two parts: on the one hand commands which actually typeset +% listings and on the other via |\lstset| adjustable parameters. Both could +% be implemented in terms of \lst-aspects, which are simply collections of +% public keys and commands and internal hooks and definitions. The package +% defines a couple of aspects, in particular the kernel, the main engine. +% Other aspects drive this engine, and language and style definitions tell +% the aspects how to drive. The relations between car, driver and assistant +% driver are exactly reproduced---and I'll be your driving instructor. +% +% +% \subsection{Package loading}\label{dPackageLoading} +% +% Each option in |\usepackage[|\meta{options}|]{listings}| loads an aspect or +% \emph{prevents} the package from loading it if the aspect name is +% \emph{preceded by an exclamation mark}. This mechanism was designed to clear +% up the dependencies of different package parts and to debug the package. For +% this reason there is another option: +% \begin{syntax} +% \item[0.21,,option] \texttt{noaspects}\leavevmode +% +% deletes the list of aspects to load. Note that, for example, the +% option lists |0.21,!labels,noaspects| and |noaspects| are essentially +% the same: the kernel is loaded and no other aspect. +% \end{syntax} +% This is especially useful for aspect-testing since we can load exactly the +% required parts. Note, however, that an aspect is loaded later if a predefined +% programming language requests it. One can load aspects also by hand: +% \begin{syntax} +% \item[0.20] |\lstloadaspects|\marg{comma separated list of aspect names} +% +% loads the specified aspects if they are not already loaded. +% \end{syntax} +% Here now is a list of all aspects and related keys and commands---in the hope +% that this list is complete. +% \begin{description} +% \hyphenpenalty=10000\relax \rightskip=0pt plus \linewidth\relax +% \item[\aspectname{strings}]\leavevmode +% +% \lstprintaspectkeysandcmds{strings} +% +% \item[\aspectname{comments}]\leavevmode +% +% \lstprintaspectkeysandcmds{comments} +% +% \item[\aspectname{pod}]\leavevmode +% +% \lstprintaspectkeysandcmds{pod} +% +% \item[\aspectname{escape}]\leavevmode +% +% \lstprintaspectkeysandcmds{escape} +% +% \item[\aspectname{writefile}] requires 1 |\toks|, 1 |\write| +% +% |\lst@BeginWriteFile|, |\lst@BeginAlsoWriteFile|, |\lst@EndWriteFile| +% +% \item[\aspectname{style}]\leavevmode +% +% empty style, \lstprintaspectkeysandcmds{style} +% +% \item[\aspectname{language}]\leavevmode +% +% empty language, \lstprintaspectkeysandcmds{language} +% +% \item[\aspectname{keywords}]\leavevmode +% +% \lstprintaspectkeysandcmds{keywords} +% +% \item[\aspectname{emph}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{emph} +% +% \item[\aspectname{html}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{html} +% +% \item[\aspectname{tex}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{tex} +% +% \item[\aspectname{directives}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{directives} +% +% \item[\aspectname{index}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{index} +% +% \item[\aspectname{procnames}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{procnames} +% +% \item[\aspectname{keywordcomments}] +% requires \aspectname{keywords}, \aspectname{comments} +% +% \lstprintaspectkeysandcmds{keywordcomments} +% +% \item[\aspectname{labels}] requires 2 |\count| +% +% \lstprintaspectkeysandcmds{labels} +% +% \item[\aspectname{lineshape}] requires 2 |\dimen| +% +% \lstprintaspectkeysandcmds{lineshape} +% +% \item[\aspectname{frames}] requires \aspectname{lineshape} +% +% \lstprintaspectkeysandcmds{frames} +% +% \item[\aspectname{make}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{make} +% +% \item[\aspectname{doc}] requires \aspectname{writefile} and 1 |\box| +% +% \lstprintaspectkeysandcmds{doc} +% +% \item[\aspectname{0.21}] defines old keys in terms of the new ones. +% \item[\aspectname{fancyvrb}] requires 1 |\box| +% +% \lstprintaspectkeysandcmds{fancyvrb} +% +% \item[\aspectname{lgrind}]\leavevmode +% +% \lstprintaspectkeysandcmds{lgrind} +% +% \item[\aspectname{hyper}] requires \aspectname{keywords} +% +% \lstprintaspectkeysandcmds{hyper} +% \end{description} +% The kernel allocates 6 |\count|, 4 |\dimen| and 1 |\toks|. +% Moreover it defines the following keys, commands, and environments: +% \begin{itemize}\item[] +% \hyphenpenalty=10000\relax \rightskip=0pt plus \linewidth\relax +% \lstprintaspectkeysandcmds{kernel}, \keyname{fancyvrb} +% \end{itemize} +% +% +% \subsection{How to define \lst-aspects}\label{dHowToDefineLstAspects} +% +% There are at least three ways to add new functionality: (a) you write an +% aspect of general interest, send it to me, and I'll just paste it into the +% implementation; (b) you write a `local' aspect not of general interest; or +% (c) you have an idea for an aspect and make me writing it. (a) and (b) are +% good choices.^^A :-) +% +% An aspect definition starts with |\lst@BeginAspect| plus arguments and ends +% with the next |\lst@EndAspect|. In particular, aspect definitions can't be +% nested. +% \begin{syntax} +% \item[0.20] |\lst@BeginAspect|[\oarg{list of required aspects}]\marg{aspect name} +% \item[0.20] |\lst@EndAspect| +% \end{syntax} +% The optional list is a comma separated list of required aspect names. +% The complete aspect is not defined in each of the following cases: +% \begin{enumerate} +% \item \meta{aspect name} is empty. +% \item The aspect is already defined. +% \item A required aspect is neither defined nor loadable via +% |\lstloadaspects|. +% \end{enumerate} +% Consequently you can't define a part of an aspect and later on another part. +% But it is possible to define aspect $A_1$ and later aspect $A_2$ which +% requires $A_1$. +% \begin{advise} +% \item Put local add-ons into `\texttt{lstmisc0.sty}'---this file is searched +% first by default. If you want to make add-ons for one particular +% document just replace the surrounding `|\lst@BeginAspect|' and +% `|\lst@EndAspect|' by `|\makeatletter|' and `|\makeatother|' and use +% the definitions in the preamble of your document. However, you have to +% load required aspects on your own. +% \end{advise} +% You can put any \TeX\ material in between the two commands, but note that +% definitions must be |\global| if you need them later---\LaTeX's |\newcommand| +% makes local definitions and can't be preceded by |\global|. So use the +% following commands, |\gdef|, and commands described in later sections. +% \begin{syntax} +% \item[0.20] |\lst@UserCommand|\meta{macro}\meta{parameter text}\marg{replacement text} +% +% The macro is (mainly) equivalent to |\gdef|. The purpose is to +% distinguish user commands and internal global definitions. +% +% \item[0.19] |\lst@Key|\marg{key name}\marg{init value}[\oarg{default value}]\marg{definition} +% \item[0.19] |\lst@Key|\marg{key name}|\relax|[\oarg{default value}]\marg{definition} +% +% defines a key using the \packagename{keyval} package from David +% Carlisle. \meta{definition} is the replacement text of a macro with +% one parameter. The argument is either the value from `key=value' or +% \meta{default value} if no `=value' is given. The helper macros +% |\lstKV@...| below might simplify \meta{definition}. +% +% The key is not initialized if the second argument is |\relax|. +% Otherwise \meta{init value} is the initial value given to the key. +% Note that we locally switch to |\globalsdefs=1| to ensure that +% initialization is not effected by grouping. +% +% \item[0.19] |\lst@AddToHook|\marg{name of hook}\marg{\TeX\ material} +% +% adds \TeX\ material at predefined points. Section \ref{dHooks} lists +% all hooks and where they are defined respectively executed. +% |\lst@AddToHook{A}{\csa}| before |\lst@AddToHook{A}{\csb}| +% \emph{does not} guarantee that |\csa| is executed before |\csb|. +% +% \item[0.20] |\lst@AddToHookExe|\marg{name of hook}\marg{\TeX\ material} +% +% also executes \meta{\TeX\ material} for initialization. You might use +% local variables---local in the sense of \TeX\ and/or usual programming +% languages---but when the code is executed for initialization all +% assignments are global: we set |\globaldefs| locally to one. +% +% \item[0.20] |\lst@UseHook|\marg{name of hook} +% +% executes the hook. +% \end{syntax} +% \begin{advise} +% \item Let's look at two examples. The first extends the package by adding +% some hook-material. If you want status messages, you might write +% \begin{verbatim} +% \lst@AddToHook{Init}{\message{\MessageBreak Processing listing ...}} +% \lst@AddToHook{DeInit}{\message{complete.\MessageBreak}}\end{verbatim} +% The second example introduces two keys to let the user control the +% messages. The macro |\lst@AddTo| is described in section +% \ref{dGeneralPurposeMacros}. +% \begin{verbatim} +% \lst@BeginAspect{message} +% \lst@Key{message}{Annoying message.}{\gdef\lst@message{#1}} +% \lst@Key{moremessage}\relax{\lst@AddTo\lst@message{\MessageBreak#1}} +% \lst@AddToHook{Init}{\typeout{\MessageBreak\lst@message}} +% \lst@EndAspect\end{verbatim} +% However, there are certainly aspects which are more useful. +% \end{advise} +% The following macros can be used in the \meta{definition} argument of the +% |\lst@Key| command to evaluate the argument. The additional prefix |KV| +% refers to the \packagename{keyval} package. +% \begin{syntax} +% \item[0.19] |\lstKV@SetIf|\marg{value}\meta{if macro} +% +% \meta{if macro} becomes |\iftrue| if the first character of +% \meta{value} equals |t| or |T|. Otherwise it becomes |\iffalse|. +% Usually you will use |#1| as \meta{value}. +% +% \item[1.0] \cs{lstKV@SwitchCases}\marg{value}\\ +% |{|\meta{string 1}|&|\meta{execute 1}|\\|\\ +% | |\meta{string 2}|&|\meta{execute 2}|\\|\\ +% \hbox to 3em{\hfill\vdots}\\ +% | |\meta{string $n$}|&|\meta{execute $n$}|}|\marg{else} +% +% Either execute \meta{else} or the \meta{value} matching part. +% +% \item[0.20] |\lstKV@TwoArg|\marg{value}\marg{subdefinition} +% \item[0.20] |\lstKV@ThreeArg|\marg{value}\marg{subdefinition} +% \item[0.20] |\lstKV@FourArg|\marg{value}\marg{subdefinition} +% +% \meta{subdefinition} is the replacement text of a macro with two, +% three, and four parameters. We call this macro with the arguments given +% by \meta{value}. Empty arguments are added if necessary. +% +% \item[0.19] |\lstKV@OptArg|\oarg{default arg.}\marg{value}\marg{subdefinition} +% +% |[|\meta{default arg.}|]| is \emph{not} optional. \meta{subdefinition} +% is the replacement text of a macro with parameter text |[##1]##2|. +% Note that the macro parameter character |#| is doubled since used +% within another macro. \meta{subdefinition} accesses these arguments +% via |##1| and |##2|. +% +% \meta{value} is usually the argument |#1| passed by the +% \packagename{keyval} package. If \meta{value} has no optional argument, +% \meta{default arg.} is inserted to provide the arguments to +% \meta{subdefinition}. +% +% \item[0.21] |\lstKV@XOptArg|\oarg{default arg.}\marg{value}\meta{submacro} +% +% Same as |\lstKV@OptArg| but the third argument \meta{submacro} is +% already a definition and not replacement text. +% +% \item[0.20] |\lstKV@CSTwoArg|\marg{value}\marg{subdefinition} +% +% \meta{value} is a \texttt comma \texttt separated list of one or two +% arguments. These are given to the subdefinition which is the +% replacement text of a macro with two parameters. An empty second +% argument is added if necessary. +% \end{syntax} +% \begin{advise} +% \item One more example. The key `\keyname{sensitive}' belongs to the aspect +% \aspectname{keywords}. Therefore it is defined in between +% `|\lst@BeginAspect{keywords}|' and `|\lst@EndAspect|', which is not shown +% here. +% \begin{verbatim} +% \lst@Key{sensitive}\relax[t]{\lstKV@SetIf{#1}\lst@ifsensitive} +% \lst@AddToHookExe{SetLanguage}{\let\lst@ifsensitive\iftrue}\end{verbatim} +% The last line is equivalent to +% \begin{verbatim} +% \lst@AddToHook{SetLanguage}{\let\lst@ifsensitive\iftrue} +% \global\let\lst@ifsensitive\iftrue\end{verbatim} +% We initialize the variable globally since the user might request an +% aspect in a group. Afterwards the variable is used locally---there is +% no |\global| in \meta{\TeX\ material}. Note that we could define and +% init the key as follows: +% \begin{verbatim} +% \lst@Key{sensitive}t[t]{\lstKV@SetIf{#1}\lst@ifsensitive} +% \lst@AddToHook{SetLanguage}{\let\lst@ifsensitive\iftrue}\end{verbatim} +%\end{advise} +% +% +% \subsection{Internal modes}\label{dInternalModes} +% +% You probably know \TeX's conditional commands |\ifhmode|, |\ifvmode|, +% |\ifmmode|, and |\ifinner|. They tell you whether \TeX\ is in (restricted) +% horizontal or (internal) vertical or in (nondisplay) mathematical mode. For +% example, true |\ifhmode| and true |\ifinner| indicate restricted horizontal +% mode, which means that you are in a |\hbox|. The typical user doesn't care +% about such modes; \TeX/\LaTeX\ manages all this. But since you're reading the +% developer's guide, we discuss the analogue for the \packagename{listings} +% package now. It uses modes to distinguish comments from strings, `comment +% lines' from `single comments', and so on. +% +% The package is in `no mode' before reading the source code. In the phase of +% initialization it goes to `processing mode'. Afterwards the mode depends on +% the actual source code. For example, consider the line +% \begin{verbatim} +% "string" // comment\end{verbatim} +% and assume \texttt{language=C++}. Reading the string delimiter, the package +% enters `string mode' and processes the string. The matching closing delimiter +% leaves the mode, i.e.\ switches back to the general `processing mode'. Coming +% to the two slashes, the package detects a comment line; it therefore enters +% `comment line mode' and outputs the slashes. Usually this mode lasts to the +% end of line. +% +% But with \texttt{textcl=true} the \aspectname{escape} aspect immediately +% leaves `comment line mode', interrupts the current mode sequence, and enters +% `\TeX\ comment line mode'. At the end of line we reenter the previous mode +% sequence `no mode' $\to$ 'processing mode'. This escape to \LaTeX\ works +% since `no mode' implies that \TeX's characters and catcodes are present, +% whereas `processing mode' means that \packagename{listings}' characters and +% catcodes are active. +% +% \begin{table}[htbp] +% \caption{Internal modes}\label{dDefinedInternalModes} +% \def\lsttabspace{\hspace*{1em}\hfill} +% \begin{tabular}{@{}lp{0.56\linewidth}@{}} +% aspect\lsttabspace\meta{mode name} & Usage/We are processing \ldots\\ +% \noalign{\smallskip} +% kernel\lsttabspace |\lst@nomode| & +% If this mode is active, \TeX's `character table' is present; the other +% implication is not true.

Most features use dynamically created mode numbers, for +% example all strings and comments. Each aspect may define its own mode(s) +% simply by allocating it/\allowbreak them inside the aspect definition. +% \begin{syntax} +% \item[0.19] |\lst@NewMode|\meta{mode \textup(control sequence\textup)} +% +% defines a new static mode, which is a nonnegative integer assigned to +% \meta{mode}. \meta{mode} should have the prefix \texttt{lst@} and +% suffix \texttt{mode}. +% +% \item[0.21] |\lst@UseDynamicMode|\marg{token\textup(s\textup)} +% +% inserts a dynamic mode number as argument to the token(s). +% +% This macro cannot be used to get a mode number when an aspect is +% loaded or defined. It can only be used every listing in the process +% of initialization, e.g.~to define comments when the character table +% is selected. +% +% \item[0.19,,changed] |\lst@EnterMode|\meta{mode}\marg{start tokens} +% +% opens a group level, enters the mode, and executes \meta{start tokens}. +% +% Use |\lst@modetrue| in \meta{start tokens} to prohibit future mode +% changes---except leaving the mode, of course. You must test yourself +% whether you're allowed to enter, see below. +% +% \item[0.19] |\lst@LeaveMode| +% +% returns to the previous mode by closing a group level if and only if +% the current mode isn't |\lst@nomode| already. You must test yourself +% whether you're allowed to leave a mode, see below. +% +%\iffalse +% \item[0.19] |\lst@LeaveAllModes| +% +% returns to |\lst@nomode|. +% This is some kind of emergency macro, so don't use it! +%\fi +% +% \item[0.19] |\lst@InterruptModes| +% \item[0.19] |\lst@ReenterModes| +% +% The first command returns to |\lst@nomode|, but saves the current mode +% sequence on a special stack. Afterwards the second macro returns to the +% previous mode. In between these commands you may enter any mode you +% want. In particular you can interrupt modes, enter some modes, and say +% `interrupt modes' again. Then two re-enters will take you back in front +% of the first `interrupt modes'. +% +% Remember that |\lst@nomode| implies that \TeX's character table is +% active. +% \end{syntax} +% Some variables show the internal state of processing. You are allowed to read +% them, but \emph{direct write access is prohibited}. Note: |\lst@ifmode| is +% \emph{not} obsolete since there is no relation between the boolean and the +% current mode. It will happen that we enter a mode without setting +% |\lst@ifmode| true, and we'll set it true without assigning any mode! +% \begin{syntax} +% \item[0.18,,counter] |\lst@mode| +% +% keeps the current mode number. Use |\ifnum\lst@mode=|\meta{mode name} +% to test against a mode. Don't modify the counter directly! +% +% \item[0.18,,boolean] |\lst@ifmode| +% +% No mode change is allowed if this boolean is true---except leaving the +% current mode. Use |\lst@modetrue| to modify this variable, but do it +% only in \meta{start tokens}. +% +% \item[1.0,,boolean] |\lst@ifLmode| +% +% Indicates whether the current mode ends at end of line. +% \end{syntax} +% +% +% \subsection{Hooks}\label{dHooks} +% +% Several problems arise if you want to define an aspect. +% You should and/or must +% (a) find additional functionality (of general interest) and implement it, +% (b) create the user interface, and +% (c) interface with the \packagename{listings} package, i.e.~find correct +% hooks and insert appropriate \TeX\ material. +% (a) is out of the scope of this developer's guide. The commands |\lstKV@...| +% in section \ref{dHowToDefineLstAspects} might help you with (b). Here now we +% describe all hooks of the \packagename{listings} package. +% +% All hooks are executed inside an overall group. This group starts somewhere +% near the beginning and ends somewhere at the end of each listing. Don't make +% any other assumptions on grouping. So define variables globally if it's +% necessary---and be alert of side effects if you don't use your own groups. +% \begin{syntax} +% \item \hookname{AfterBeginComment} +% +% is executed after the package has entered comment mode. +% The starting delimiter is usually typeset when the hook is called. +% +% \item \hookname{BoxUnsafe} +% +% Contains all material to deactivate all commands and registers which +% are possibly unsafe inside |\hbox|. It is used whenever the package +% makes a box around a listing and for \packagename{fancyvrb} support. +% +% \item \hookname{DeInit} +% +% Called at the very end of a listing but before closing the box from +% \hookname{BoxUnsafe} or ending a float. +% +% \item \hookname{DetectKeywords} +% +% This \hookname{Output} subhook is executed if and only if mode changes +% are allowed, i.e.~if and only if the package doesn't process a comment, +% string, and so on---see section \ref{dInternalModes}. +% +% \item \hookname{DisplayStyle} +% +% deactivates/activates features for displaystyle listings. +% +% \item \hookname{EmptyStyle} +% +% Executed to select the `empty' style---except the user has redefined +% the style. +% +% \item \hookname{EndGroup} +% +% Executed whenever the package closes a group, e.g.~at end of comment or +% string. +% +% \item \hookname{EOL} +% +% Called at each end of \emph{input} line, right before +% \hookname{InitVarsEOL}. +% +% \item \hookname{EveryLine} +% +% Executed at the beginning of each \emph{output} line, i.e.~more than +% once for broken lines. This hook must not change the horizontal or +% vertical position. +% +% \item \hookname{EveryPar} +% +% Executed once for each input line when the output starts. This hook +% must not change the horizontal or vertical position. +% +%^^A \item \hookname{ExcludeDelims} +%^^A +%^^A Executed by the \keyname{excludedelims} key before the excluded +%^^A delimiters are determined. +%^^A +% \item \hookname{ExitVars} +% +% Executed right before \hookname{DeInit}. +% +% \item \hookname{FontAdjust} +% +% adjusts font specific internal values (currently |\lst@width| only). +% +% \item \hookname{Init} +% +% Executed once each listing to initialize things before the character +% table is changed. It is called after \hookname{PreInit} and before +% \hookname{InitVars}. +% +% \item \hookname{InitVars} +% +% Called to init variables each listing. +% +% \item \hookname{InitVarsBOL} +% +% initializes variables at the beginning of each input line. +% +% \item \hookname{InitVarsEOL} +% +% updates variables at the end of each input line. +% +% \item \hookname{ModeTrue} +% +% executed by the package when mode changes become illegal. +% Here keyword detection is switched off for comments and strings. +% +% \item \hookname{OnEmptyLine} +% +% executed \emph{before} the package outputs an empty line. +% +% \item \hookname{OnNewLine} +% +% executed \emph{before} the package starts one or more new lines, +% i.e.~before saying |\par\noindent\hbox{}| (roughly speaking). +% +% \item \hookname{Output} +% +% Called before an identifier is printed. +% If you want a special printing style, modify |\lst@thestyle|. +% +% \item \hookname{OutputBox} +% +% used inside each output box. Currently it is only used to make the +% package work together with Lambda---hopefully. +% +% \item \hookname{OutputOther} +% +% Called before other character strings are printed. +% If you want a special printing style, modify |\lst@thestyle|. +% +% \item \hookname{PostOutput} +% +% Called after printing an identifier or any other output unit. +% +% \item \hookname{PostTrackKeywords} +% +% is a very special \hookname{Init} subhook to insert keyword tests and +% define keywords on demand. +% This hook is called after \hookname{TrackKeywords}. +% +% \item \hookname{PreInit} +% +% Called right before \hookname{Init} hook. +% +% \item \hookname{PreSet} +% +% Each typesetting command/environment calls this hook to initialize +% internals before any user supplied key is set. +% +% \item \hookname{SelectCharTable} +% +% is executed after the package has selected the standard character +% table. Aspects adjust the character table here and define string and +% comment delimiters, and such. +% +% \item \hookname{SetFormat} +% +% Called before internal assignments for setting a format are made. +% This hook determines which parameters are reset every format selection. +% +% \item \hookname{SetStyle} +% +% Called before internal assignments for setting a style are made. +% This hook determines which parameters are reset every style selection. +% +% \item \hookname{SetLanguage} +% +% Called before internal assignments for setting a language are made. +% This hook determines which parameters are reset every language +% selection. +% +% \item \hookname{TextStyle} +% +% deactivates/activates features for textstyle listings. +% +% \item \hookname{TrackKeywords} +% +% is a very special \hookname{Init} subhook to insert keyword tests and +% define keywords on demand. +% This hook is called before \hookname{PostTrackKeywords}. +% \end{syntax} +% +% +% \subsection{Character tables}\label{dCharacterTables} +% +% Now you know how a car looks like, and you can get a driving license if you +% take some practice. But you will have difficulties if you want to make heavy +% alterations to the car. So let's take a closer look and come to the most +% difficult part: the engine. We'll have a look at the big picture and fill in +% the details step by step. For our purpose it's good to override \TeX's +% character table. First we define a standard character table which contains +% \begin{itemize} +% \item letters: characters identifiers are out of, +% \item digits: characters for identifiers or numerical constants, +% \item spaces: characters treated as blank spaces, +% \item tabulators: characters treated as tabulators, +% \item form feeds: characters treated as form feed characters, and +% \item others: all other characters. +% \end{itemize} +% This character table is altered depending on the current programming language. +% We may define string and comment delimiters or other special characters. +% Table \ref{rStdCharTable} on page \pageref{rStdCharTable} shows the standard +% character table. It can be modified with the keys \keyname{alsoletter}, +% \keyname{alsodigit}, and \keyname{alsoother}. +% +% How do these `classes' work together? Let's say that the current character +% string is `|tr|'. Then letter `|y|' simply appends the letter and we get +% `|try|'. The next nonletter (and nondigit) causes the output of the +% characters. Then we collect all coming nonletters until reaching a letter +% again. This causes the output of the nonletters, and so on. Internally each +% character becomes active in the sense of \TeX\ and is defined to do the right +% thing, e.g.~we say +% \begin{verbatim} +% \def A{\lst@ProcessLetter A}\end{verbatim} +% where the first `|A|' is active and the second has letter catcode 11. +% The macro |\lst@ProcessLetter| gets one token and treats it as a letter. +% The following macros exist, where the last three get no explicit argument. +% \begin{syntax} +% \item[0.18] |\lst@ProcessLetter| \meta{spec.\ token} +% \item[0.18] |\lst@ProcessDigit| \meta{spec.\ token} +% \item[0.18] |\lst@ProcessOther| \meta{spec.\ token} +% \item[0.18] |\lst@ProcessTabulator| +% \item[0.18] |\lst@ProcessSpace| +% \item[0.20] |\lst@ProcessFormFeed| +% \end{syntax} +% \meta{spec.\ token} is supposed to do two things. Usually it expands to +% a printable version of the character. But if |\lst@UM| is equivalent to +% |\@empty|, \meta{spec.\ token} must expand to a \emph{character token}. +% For example, the sharp usually expands to |\#|, which is defined via +% |\chardef| and is not a character token. But if |\lst@UM| is equivalent to +% |\@empty|, the sharp expands to the character `|#|' (catcode 12). Note: +% \emph{Changes to} |\lst@UM| \emph{must be locally.} However, there should +% be no need to do such basic things yourself. The \packagename{listings} +% package provides advanced macros which use that feature, +% e.g.~|\lst@InstallKeywords| in section \ref{dKeywordsAndWorkingIdentifiers}. +% +% \begin{syntax} +% \item[0.18] |\lst@Def|\marg{character code}\meta{parameter text}\marg{definition} +% \item[0.18] |\lst@Let|\marg{character code}\meta{token} +% +% defines the specified character respectively assigns \meta{token}. +% The catcode table if not affected. Be careful if your definition has +% parameters: it is not safe to read more than one character ahead. +% Moreover, the argument can be \emph{arbitrary}; somtimes it's the next +% source code character, sometimes it's some code of the +% \packagename{listings} package, e.g.~|\relax|, |\@empty|, |\else|, +% |\fi|, and so on. Therefore don't use \TeX's ord-operator |`| on such +% an argument, e.g.~don't write |\ifnum`#1=65| to test against `|A|'. +% +% |\lst@Def| and |\lst@Let| are relatively slow. The real definition of +% the standard character table differs from the following example, but it +% could begin with +% \begin{verbatim} +% \lst@Def{9}{\lst@ProcessTabulator} +% \lst@Def{32}{\lst@ProcessSpace} +% \lst@Def{48}{\lst@ProcessDigit 0} +% \lst@Def{65}{\lst@ProcessLetter A}\end{verbatim} +% +%\iffalse +% \item[0.20] |\lst@activecharstrue| +% \item[0.20] |\lst@activecharsfalse| +% +% control whether selecting the character table also makes all characters +% active (standard/extended). This is usually true and therefore default. +% Only the \packagename{fancyvrb} interface sets it locally false. +%\fi +% \end{syntax} +% That's enough for the moment. Section \ref{dUsefulInternalDefinitions} +% presents advanced definitions to manipulate the character table, in +% particular how to add new comment or string types. +% +% +% \subsection{On the output} +% +% The \packagename{listings} package uses some variables to keep the output +% data. Write access is not recommended. Let's start with the easy ones. +% \begin{syntax} +% \item[0.17,,data] |\lst@lastother| +% +% equals \meta{spec.\ token} version of the last processed +% nonidentifier-character. Since programming languages redefine the +% standard character table, we use the original \meta{spec.\ token}. +% For example, if a double quote was processed last, |\lst@lastother| +% is not equivalent to the macro which enters and leaves string mode. +% It's equivalent to |\lstum@"|, where |"| belongs to the control +% sequence. Remember that \meta{spec.\ token} expands either to a +% printable or to a token character. +% +% |\lst@lastother| is equivalent to |\@empty| if such a character is not +% available, e.g.~at the beginning of a line. Sometimes an indentifier +% has already been printed after processing the last `other' character, +% i.e.~the character is far, far away. In this case |\lst@lastother| +% equals |\relax|. +% +% \item[0.17] |\lst@outputspace| +% +% Use this predefined \meta{spec.\ token} (obviously for character code +% 32) to test against |\lst@lastother|. +% +% \item[0.20] |\lstum@backslash| +% +% Use this predefined \meta{spec.\ token} (for character code 92) to test +% against |\lst@lastother|. In the replacement text for |\lst@Def| one +% could write |\ifx| |\lst@lastother| |\lstum@backslash| \ldots\ to test +% whether the last character has been a backslash. +% +% \item[0.20] |\lst@SaveOutputDef|\marg{character code}\meta{macro} +% +% Stores the \meta{spec.\ token} corresponding to \meta{character code} +% in \meta{macro}. This is the only safe way to get a correct meaning to +% test against |\lst@lastother|, for example +% |\lst@SaveOutputDef{"5C}\lstum@backslash|. +% +% You'll get a ``runaway argument'' error if \meta{character code} is not +% between 33 and 126 (inclusive). +% \end{syntax} +% Now let's turn to the macros dealing a bit more with the output data and +% state. +% \begin{syntax} +% \item[1.0] |\lst@XPrintToken| +% +% outputs the current character string and resets it. This macro keeps +% track of all variables described here. +% +% \item[0.18,,token] |\lst@token| +% +% contains the current character string. Each `character' usually +% expands to its printable version, but it must expand to a character +% token if |\lst@UM| is equivalent to |\@empty|. +% +% \item[0.12,,counter] |\lst@length| +% +% is the length of the current character string. +% +% \item[0.12,,dimension] |\lst@width| +% +% is the width of a single character box. +% +% \item[0.20,,global dimension] |\lst@currlwidth| +% +% is the width of so far printed line. +% +% \item[0.18,,global counter] |\lst@column| +% \item[0.12,,global counter] |\lst@pos| (nonpositive) +% +% |\lst@column|$-$|\lst@pos| is the length of the so far printed line. +% We use two counters since this simplifies tabulator handling: +% |\lst@pos| is a nonpositive representative of `length of so far +% printed line' modulo \keyname{tabsize}. +% It's usually not the biggest nonpositive representative. +% +% \item[0.20] |\lst@CalcColumn| +% +% |\@tempcnta| gets |\lst@column| $-$ |\lst@pos| $+$ |\lst@length|. +% This is the current column number minus one, or the current column +% number zero based. +% +% \item[0.18,,global dimension] |\lst@lostspace| +% +% equals `lost' space: desired current line width minus real line width. +% Whenever this dimension is positive the flexible column format can use +% this space to fix the column alignment. +% \end{syntax} +% +% +% \section{Package extensions}\label{dPackageExtensions} +% +% +% \subsection{Keywords and working identifiers}\label{dKeywordsAndWorkingIdentifiers} +% +% The \aspectname{keywords} aspect defines two main macros. Their respective +% syntax is shown on the left. On the right you'll find examples how the +% package actually defines some keys. +% \begin{syntax} +% \item[0.21] +% \cs{lst@InstallFamily} +% +% \marg{prefix}\syntaxfill \texttt k\\ +% \marg{name}\syntaxfill |{keywords}|\\ +% \marg{style name}\syntaxfill |{keywordstyle}|\\ +% \marg{style init}\syntaxfill |\bfseries|\\ +% \marg{default style name}\syntaxfill |{keywordstyle}|\\ +% \marg{working procedure}\syntaxfill |{}|\\ +% \meta{\alternative{l,o}}\syntaxfill |l|\\ +% \meta{\alternative{d,o}}\syntaxfill |d| +% +% installs either a keyword or `working' class of identifiers according +% to whether \meta{working procedure} is empty. +% +% The three keys \meta{name}, \keyname{more}\meta{name} and +% \keyname{delete}\meta{name}, and if not empty \meta{style name} are +% defined. The first order member of the latter one is initialized with +% \meta{style init} if not equivalent to |\relax|. If the user leaves a +% class style undefined, \meta{default style name} is used instead. +% Thus, make sure that this style is always defined. In the example, +% the first order keywordstyle is set to |\bfseries| and is the default +% for all other classes. +% +% If \meta{working procedure} is not empty, this code is executed when +% reaching such an (user defined) identifier. \meta{working procedure} +% takes exactly one argument, namely the class number to which the +% actual identifier belongs to. If the code uses variables and requires +% values from previous calls, you must define these variables +% |\global|ly. It's not sure whether working procedures are executed +% inside a (separate) group or not. +% +% \texttt l indicates a language key, i.e.~the lists are reset every +% language selection. \texttt o stands for `other' key. +% The keyword respectively working test is either installed at the +% \hookname{DetectKeyword} or \hookname{Output} hook according to +% \meta{\alternative{d,o}}. +% +% \item[0.20] +% \cs{lst@InstallKeywords} +% +% \marg{prefix}\syntaxfill \texttt{cs}\\ +% \marg{name}\syntaxfill |{texcs}|\\ +% \marg{style name}\syntaxfill |{texcsstyle}|\\ +% \marg{style init}\syntaxfill |\relax|\\ +% \marg{default style name}\syntaxfill |{keywordstyle}|\\ +% \marg{working procedure}\syntaxfill see below\\ +% \meta{\alternative{l,o}}\syntaxfill |l|\\ +% \meta{\alternative{d,o}}\syntaxfill |d| +% +% Same parameters, same functionality with one execption. The macro +% installs exactly one keyword class and not a whole family. Therefore +% the argument to \meta{working procedure} is constant (currently empty). +% +% The working procedure of the example reads as follows.\vspace*{-.5\baselineskip} +% \begin{verbatim} +% {\ifx\lst@lastother\lstum@backslash +% \let\lst@thestyle\lst@texcsstyle +% \fi}\end{verbatim} +%\vspace*{-.5\baselineskip} +% What does this procedure do? First of all it is called only if a +% keyword from the user supplied list (or language definition) is found. +% The procedure now checks for a preceding backslash and sets the output +% style accordingly. +% +%\iffalse +% \item[0.20] |\lst@InstallTest|\marg{prefix}\syntaxbreak +% |\lst@|\meta{name}|@list||\lst@|\meta{name}~|\lst@g|\meta{name}|@list||\lst@g|\meta{name}\syntaxbreak +% |\lst@g|\meta{name}|@sty|~\meta{\alternative{w,s}}\meta{\alternative{d,o}} +% +% installs a `working identifier' test or keyword style depending on +% \meta{\alternative{w,s}}. |\lst@g|\meta{name}|@sty| contains the +% working procedure or style macro. Note that the behaviour of the tests +% depends on the \texttt{savemem} option. +% The keyword respectively working test is either installed at the +% \hookname{DetectKeyword} or \hookname{Output} hook according to +% \meta{\alternative{d,o}}. +% +%^^A Either each call of this macro or each different \meta{prefix} inserts +%^^A another test (depending on the \texttt{savemem} option). +% +% |\lst@|\meta{name} contains the current identifier list and +% |\lst@|\meta{name}|@list| a `|\lst@|\meta{$n_i$}|\lst@g|\meta{$n_i$}' +% sequence of currently used classes. If no other classes are used, +% this equals |\lst@|\meta{name}|\lst@g|\meta{name}. The global versions +% |\lst@g|\ldots\ are used to keep track of the keywords. +% (This description needs improvement.) +%\fi +% \end{syntax} +% +% +% \subsection{Delimiters} +% +% We describe two stages: adding a new delimiter type to an existing class of +% delimiters and writing a new class. Each class has its name; currently exist +% \texttt{Comment}, \texttt{String}, and \texttt{Delim}. As you know, the +% latter and the first both provide the type \texttt l, but there is no string +% which starts with the given delimiter and ends at end of line. So we'll add +% it now! +% +% First of all we extend the list of string types by +% \begin{verbatim} +% \lst@AddTo\lst@stringtypes{,l}\end{verbatim} +% Then we must provide the macro which takes the user supplied delimiter and +% makes appropriate definitions. The command name consists of the prefix +% |\lst@|, the delimiter name, |DM| for using dynamic modes, and |@| followed +% by the type. +% \begin{verbatim} +% \gdef\lst@StringDM@l#1#2\@empty#3#4#5{% +% \lst@CArg #2\relax\lst@DefDelimB{}{}{}#3{#1}{#5\lst@Lmodetrue}}\end{verbatim} +% You can put these three lines into a \texttt{.sty}-file or surround them by +% |\makeatletter| and |\makeatother| in the preamble of a document. +% And that's all! +%{\makeatletter +%\lst@AddTo\lst@stringtypes{,l} +%\gdef\lst@StringDM@l#1#2\@empty#3#4#5{^^A +% \lst@CArg #2\relax\lst@DefDelimB{}{}{}#3{#1}{#5\lst@Lmodetrue}} +%} +% \begin{lstsample}{}{} +% \lstset{string=[l]//} +% \begin{lstlisting} +% // This is a string. +% This isn't a string. +% \end{lstlisting} +% \end{lstsample} +% You want more details, of course. Let's begin with the arguments. +% \begin{itemize} +% \item The first argument \emph{after} |\@empty| is used to start the +% delimiter. It's provided by the delimiter class. +% \item The second argument \emph{after} |\@empty| is used to end the +% delimiter. It's also provided by the delimiter class. We didn't +% need it in the example, see the explanation below. +% \item The third argument \emph{after} |\@empty| is +% \marg{style}\meta{start tokens}. +% This with a preceding |\def\lst@currstyle| is used as argument to +% |\lst@EnterMode|. The delimiter class also provides it. In the +% example we `extended' |#5| by |\lst@Lmodetrue| (line mode true). +% The mode automatically ends at end of line, so we didn't need the +% end-delimiter argument. +% \end{itemize} +% And now for the other arguments. In case of dynamic modes, the first argument +% is the mode number. Then follow the user supplied delimiter(s) whose number +% must match the remaining arguments up to |\@empty|. For non-dynamic modes, +% you must either allocate a static mode yourself or use a predefined mode +% number. The delimiters then start with the first argument. +% +% Eventually let's look at the replacement text of the macro. The sequence +% |\lst@CArg #2\relax| puts two required arguments after |\lst@DefDelimB|. +% The syntax of the latter macro is +% \begin{syntax} +% \item[1.0] \cs{lst@DefDelimB} +% +% |{|\meta{1st}\meta{2nd}\marg{rest}|}|\syntaxfill |{//{}}|\\ +% \meta{save 1st}\syntaxfill |\lst@c/0|\\ +% \marg{execute}\syntaxfill|{}|\\ +% \marg{delim~exe~modetrue}\syntaxfill|{}|\\ +% \marg{delim~exe~modefalse}\syntaxfill|{}|\\ +% \meta{start-delimiter macro}\syntaxfill|#3|\\ +% \meta{mode number}\syntaxfill |{#1}|\\ +% |{|\marg{style}\meta{start tokens}|}|\syntaxfill |{#5\lst@Lmodetrue}| +% +% defines \meta{1st}\meta{2nd}\meta{rest} as starting-delimiter. +% \meta{execute} is executed when the package comes to \meta{1st}. +% \meta{delim~exe~modetrue} and \meta{delim~exe~modefalse} are +% executed only if the whole delimiter \meta{1st}\meta{2nd}\meta{rest} +% is found. Exactly one of them is called depending on |\lst@ifmode|. +% +% By default the package enters the mode if the delimiter is found +% \emph{and} |\lst@ifmode| is false. Internally we make an appropriate +% definition of |\lst@bnext|, which can be gobbled by placing +% |\@gobblethree| at the very end of \meta{delim exe modefalse}. +% One can provide an own definition (and gobble the default). +% +% \meta{save 1st} must be an undefined macro and is used internally to +% store the previous meaning of \meta{1st}. The arguments \meta{2nd} +% and/or \meta{rest} are empty if the delimiter has strictly less than +% three characters. All characters of \meta{1st}\meta{2nd}\meta{rest} +% must already be active (if not empty). +% That's not a problem since the macro |\lst@CArgX| does this job. +% +% \item[1.0] \cs{lst@DefDelimE} +% +% |{|\meta{1st}\meta{2nd}\marg{rest}|}|\\ +% \meta{save 1st}\\ +% \marg{execute}\\ +% \marg{delim~exe~modetrue}\\ +% \marg{delim~exe~modefalse}\\ +% \meta{end-delimiter macro}\\ +% \meta{mode number} +% +% Ditto for ending-delimiter with slight differences: +% \meta{delim~exe~modetrue} and \meta{delim~exe~modefalse} are executed +% depending on whether |\lst@mode| equals \meta{mode}. +% +% The package ends the mode if the delimiter is found and |\lst@mode| +% equals \meta{mode}. Internally we make an appropriate definition of +% |\lst@enext| (not |\lst@bnext|), which can be gobbled by placing +% |\@gobblethree| at the very end of \meta{delim exe modetrue}. +% +% \item[1.0] \cs{lst@DefDelimBE} +% +% followed by the same eight arguments as for |\lst@DefDelimB| and \ldots\\ +% \meta{end-delimiter macro} +% +% This is a combination of |\lst@DefDelimB| and |\lst@DefDelimE| for the +% case of starting and ending delimiter being the same. +% \end{syntax} +% We finish the first stage by examining two easy examples. +% \texttt d-type strings are defined by +% \begin{verbatim} +% \gdef\lst@StringDM@d#1#2\@empty#3#4#5{% +% \lst@CArg #2\relax\lst@DefDelimBE{}{}{}#3{#1}{#5}#4}\end{verbatim} +% (and an entry in the list of string types). +% Not a big deal. Ditto \texttt d-type comments: +% \begin{verbatim} +% \gdef\lst@CommentDM@s#1#2#3\@empty#4#5#6{% +% \lst@CArg #2\relax\lst@DefDelimB{}{}{}#4{#1}{#6}% +% \lst@CArg #3\relax\lst@DefDelimE{}{}{}#5{#1}}\end{verbatim} +% Here we just need to use both |\lst@DefDelimB| and |\lst@DefDelimE|. +% \goodbreak +% +% So let's get to the second stage. For illustration, here's the definition of +% the \texttt{Delim} class. The respective first argument to the service macro +% makes it delete all delimiters of the class, add the delimiter, or delete +% the particular delimiter only. +% \begin{verbatim} +% \lst@Key{delim}\relax{\lst@DelimKey\@empty{#1}} +% \lst@Key{moredelim}\relax{\lst@DelimKey\relax{#1}} +% \lst@Key{deletedelim}\relax{\lst@DelimKey\@nil{#1}}\end{verbatim} +% The service macro itself calls another macro with appropriate arguments. +% \begin{verbatim} +% \gdef\lst@DelimKey#1#2{% +% \lst@Delim{}#2\relax{Delim}\lst@delimtypes #1% +% {\lst@BeginDelim\lst@EndDelim} +% i\@empty{\lst@BeginIDelim\lst@EndIDelim}}\end{verbatim} +% We have to look at those arguments. Above you can see the actual arguments +% for the \texttt{Delim} class, below are the \texttt{Comment} class ones. +% Note that the user supplied value covers the second and third line of +% arguments. +% \begin{syntax} +% \item[0.21,,changed] +% \cs{lst@Delim} +% +% \meta{default style macro}\syntaxfill \cs{lst@commentstyle}\\ \relax +% [\texttt*[\texttt*]]\texttt[\meta{type}\texttt][\texttt[\meta{style}\texttt][\texttt[\meta{type option}\texttt]]]\\ +% \meta{delimiter\textup(s\textup)}\cs{relax}\syntaxfill|#2|\cs{relax}\\ +% \marg{delimiter name}\syntaxfill|{Comment}|\\ +% \meta{delimiter types macro}\syntaxfill\texttt{\cs{lst@commenttypes}}\\ +% \alternative{\cs{@empty},\cs{@nil},\cs{relax}}\syntaxfill|#1|\\ +% \marg{begin- and end-delim macro}\syntaxfill|{|\cs{lst@BeginComment}\cs{lst@EndComment}|}|\\ +% \meta{extra prefix}\syntaxfill |i|\\ +% \meta{extra conversion}\syntaxfill |\@empty|\\ +% \marg{begin- and end-delim macro}\syntaxfill|{|\cs{lst@BeginIComment}\cs{lst@EndIComment}|}| +% +% Most arguments should be clear. We'll discuss the last four. Both +% \marg{begin- and end-delim macro} must contain exactly two control +% sequences, which are given to |\lst@|\meta{name}[|DM|]|@|\meta{type} +% to begin and end a delimiter. These are the arguments |#3| and |#4| in our +% first example of |\lst@StringDM@l|. Depending on whether the user chosen +% type starts with \meta{extra prefix}, the first two or the last control +% sequences are used. +% +% By default the package takes the delimiter(s), makes the characters active, +% and places them after |\lst@|\meta{name}[|DM|]|@|\meta{type}. If the user +% type starts with \meta{extra prefix}, \meta{extra conversion} might change +% the definition of |\lst@next| to choose a different conversion. The default +% is equivalent to |\lst@XConvert| with |\lst@false|. +% +% Note that \meta{type} never starts with \meta{extra prefix} since it is +% discarded. The functionality must be fully implemented by choosing a +% different \marg{begin- and end-delim macro} pair. +% \end{syntax} +% You might need to know the syntaxes of the \meta{begin- and end-delim macro}s. +% They are called as follows. +% \begin{syntax} +% \item[0.21] |\lst@Begin|\meta{whatever} +% +% \marg{mode} +% |{|\marg{style}\meta{start tokens}|}| +% \meta{delimiter}|\@empty| +% +% \item[0.21] |\lst@End|\meta{whatever} +% +% \marg{mode} +% \meta{delimiter}|\@empty| +% \end{syntax} +% The existing macros are internally defined in terms of |\lst@DelimOpen| and +% |\lst@DelimClose|, see the implementation. +% +% +% \subsection{Getting the kernel run} +% +% If you want new pretty-printing environments, you should be happy with +% section \ref{rEnvironments}. New commands like |\lstinline| or +% |\lstinputlisting| are more difficult. Roughly speaking you must follow +% these steps. +% \begin{enumerate} +% \item Open a group to make all changes local. +% \item \meta{Do whatever you want.} +% \item Call |\lsthk@PreSet| in any case. +% \item Now you \emph{might } want to (but need not) use |\lstset| to set some +% new values. +% \item \meta{Do whatever you want.} +% \item Execute |\lst@Init\relax| to finish initialization. +% \item \meta{Do whatever you want.} +% \item Eventually comes the source code, which is processed by the kernel. +% You must ensure that the characters are either not already read or all +% active. Moreover \emph{you} must install a way to detect the end of the +% source code. If you've reached the end, you must \ldots +% \item \ldots\ call |\lst@DeInit| to shutdown the kernel safely. +% \item \meta{Do whatever you want.} +% \item Close the group from the beginning. +% \end{enumerate} +% For example, consider the |\lstinline| command in case of being not inside an +% argument. Then the steps are as follows. +% \begin{enumerate} +% \item |\leavevmode\bgroup| opens a group. +% \item |\def\lst@boxpos{b}| `baseline' aligns the listing. +% \item |\lsthk@PreSet| +% \item |\lstset{flexiblecolumns,#1}| (|#1| is the user provided +% key=value list) +% \item |\lsthk@TextStyle| deactivates all features not safe here. +% \item |\lst@Init\relax| +% \item |\lst@Def{`#1}{\lst@DeInit\egroup}| installs the `end inline' +% detection, where |#1| is the next character after |\lstinline|. +% Moreover chr(13) is redefined to end the fragment in the same way but +% also issues an error message. +% \item Now comes the source code and \ldots +% \item \ldots\ |\lst@DeInit| (from |\lst@Def| above) ends the code snippet +% correctly. +% \item Nothing. +% \item |\egroup| (also from |\lst@Def|) closes the group. +% \end{enumerate} +% The real definition is different since we allow source code inside arguments. +% Read also section \ref{iTheInputCommand} if you really want to write +% pretty-printing commands. +% +% +% \section{Useful internal definitions}\label{dUsefulInternalDefinitions} +% +% This section requires an update. +% +% +% \subsection{General purpose macros}\label{dGeneralPurposeMacros} +% +% \begin{syntax} +% \item[0.19] |\lst@AddTo|\meta{macro}\marg{\TeX~material} +% +% adds \meta{\TeX~material} globally to the contents of \meta{macro}. +% +% \item[0.20] |\lst@Extend|\meta{macro}\marg{\TeX~material} +% +% calls |\lst@AddTo| after the first token of \meta{\TeX~material} is +% |\expand|ed|after|. For example, |\lst@Extend \a \b| merges the +% contents of the two macros and stores it globally in |\a|. +% +% \item[0.19] |\lst@lAddTo|\meta{macro}\marg{\TeX~material} +% \item[0.20] |\lst@lExtend|\meta{macro}\marg{\TeX~material} +% +% are local versions of |\lst@AddTo| and |\lst@Extend|. +% +% \item[0.18] |\lst@DeleteKeysIn|\meta{macro}\meta{macro \textup(keys to remove\textup)} +% +% Both macros contain a comma separated list of keys (or keywords). All +% keys appearing in the second macro are removed (locally) from the first. +% +% \item[0.19] |\lst@ReplaceIn|\meta{macro}\meta{macro \textup(containing replacement list\textup)} +% \item[0.20] |\lst@ReplaceInArg|\meta{macro}\marg{replacement list} +% +% The replacement list has the form $a_1b_1$\ldots$a_nb_n$, where each +% $a_i$ and $b_i$ is a character sequence (enclosed in braces if +% necessary) and may contain macros, but the first token of $b_i$ must +% not be equivalent to |\@empty|. Each sequence $a_i$ inside the first +% macro is (locally) replaced by $b_i$. +% The suffix |Arg| refers to the \emph{braced} second argument instead of +% a (nonbraced) macro. It's a hint that we get the `real' argument and +% not a `pointer' to the argument. +% +% \item[0.20] |\lst@IfSubstring|\marg{character sequence}\meta{macro}\marg{then}\marg{else} +% +% \meta{then} is executed if \meta{character sequence} is a substring of +% the contents of \meta{macro}. Otherwise \meta{else} is called. +% +% \item[0.12] |\lst@IfOneOf|\meta{character sequence}|\relax|\meta{macro}\marg{then}\marg{else} +% +% |\relax| terminates the first parameter here since it is faster than +% enclosing it in braces. \meta{macro} contains a comma separated list +% of identifiers. If the character sequence is one of these indentifiers, +% \meta{then} is executed, and otherwise \meta{else}. +% +% \item[0.21] |\lst@Swap|\marg{tok1}\marg{tok2} +% +% changes places of the following two tokens or arguments \emph{without} +% inserting braces. For example, |\lst@Swap{abc}{def}| expands to +% |defabc|. +% +% \item[0.18] |\lst@IfNextChars|\meta{macro}\marg{then}\marg{else} +% \item[0.19] |\lst@IfNextCharsArg|\marg{character sequence}\marg{then}\marg{else} +% +% Both macros execute either \meta{then} or \meta{else} according to +% whether the given character sequence respectively the contents of the +% given macro is found (after the three arguments). Note an important +% difference between these macros and \LaTeX's |\@ifnextchar|: +% We remove the characters behind the arguments until it is possible to +% decide which part must be executed. However, we save these characters +% in the macro |\lst@eaten|, so they can be inserted using \meta{then} or +% \meta{else}. +% +% \item[0.19] |\lst@IfNextCharActive|\marg{then}\marg{else} +% +% executes \meta{then} if next character is active, and \meta{else} +% otherwise. +% +% \item[0.20] |\lst@DefActive|\meta{macro}\marg{character sequence} +% +% stores the character sequence in \meta{macro}, but all characters +% become active. The string \emph{must not} contain a begin group, end +% group or escape character (|{}\|); it may contain a left brace, right +% brace or backslash with other meaning (= catcode). This command +% would be quite surplus if \meta{character sequence} is not already read +% by \TeX\ since such catcodes can be changed easily. It is explicitly +% allowed that the charcaters have been read, e.g.~in +% |\def\test{\lst@DefActive\temp{ABC}}|! +% +% Note that this macro changes |\lccode|s 0--9 without restoring them. +% +% \item[0.20] |\lst@DefOther|\meta{macro}\marg{character sequence} +% +% stores \meta{character sequence} in \meta{macro}, but all characters +% have catcode 12. Moreover all spaces are removed and control sequences +% are converted to their name without preceding backslash. For example, +% |\{ Chip \}| leads to |{Chip}| where all catcodes are 12---internally +% the primitive |\meaning| is used. +% +% \iffalse +% \item[0.19] |\lst@MakeActive|\marg{character sequence} +% +% stores the character sequence in |\lst@arg| and has the same +% restrictions as |\lst@DefActive|. If fact, the latter definition uses +% this macro here. +% \fi +% \end{syntax} +% +% +% \subsection{Character tables manipulated}\label{dCharacterTablesManipulated} +% +% \begin{syntax} +% \item[0.20] |\lst@SaveDef|\marg{character code}\meta{macro} +% +% Saves the current definition of the specified character in +% \meta{macro}. You should always save a character definition before you +% redefine it! And use the saved version instead of writing directly +% |\lst@Process|\ldots---the character could already be redefined and +% thus not equivalent to its standard definition. +% +% \item[0.20] |\lst@DefSaveDef|\marg{character code}\meta{macro}\meta{parameter text}\marg{definition} +% \item[0.20] |\lst@LetSaveDef|\marg{character code}\meta{macro}\meta{token} +% +% combine |\lst@SaveDef| and |\lst@Def| respectively |\lst@Let|. +% \end{syntax} +% Of course I shouldn't forget to mention \emph{where} to alter the character +% table. Hook material at \hookname{SelectCharTable} makes permanent changes, +% i.e.~it effects all languages. The following two keys can be used in any +% language definition and effects the particular language only. +% \begin{syntax} +% \item[0.20] |SelectCharTable=|\meta{\TeX\ code} +% \item[0.20] |MoreSelectCharTable=|\meta{\TeX\ code} +% +% uses \meta{\TeX\ code} (additionally) to select the character table. +% The code is executed after the standard character table is selected, +% but possibly before other aspects make more changes. Since previous +% meanings are always saved and executed inside the new definition, this +% should be harmless. +% \end{syntax} +% Here come two rather useless examples. Each point (full stop) will cause a +% message `|.|' on the terminal and in the |.log| file if language |useless| is +% active: +% \begin{verbatim} +% \lstdefinelanguage{useless} +% {SelectCharTable=\lst@DefSaveDef{46}% save chr(46) ... +% \lsts@point % ... in \lsts@point and ... +% {\message{.}\lsts@point}% ... use new definition +% }\end{verbatim} +% If you want to count points, you could write +% \begin{verbatim} +% \newcount\lst@points % \global +% \lst@AddToHook{Init}{\global\lst@points\z@} +% \lst@AddToHook{DeInit}{\message{Number of points: \the\lst@points}} +% \lstdefinelanguage[2]{useless} +% {SelectCharTable=\lst@DefSaveDef{46}\lsts@point +% {\global\advance\lst@points\@ne \lsts@point} +% }\end{verbatim} +% |% \global| indicates that the allocated counter is used globally. We zero +% the counter at the beginning of each listing, display a message about the +% current value at the end of a listing, and each processed point advances the +% counter by one. +% +% \begin{syntax} +% \item[0.21] |\lst@CArg|\meta{active characters}|\relax|\meta{macro} +% +% The string of active characters is split into \meta{1st}, \meta{2nd}, +% and \marg{rest}. If one doesn't exist, an empty argument is used. Then +% \meta{macro} is called with |{|\meta{1st}\meta{2nd}\marg{rest}|}| plus +% a yet undefined control sequence \meta{save 1st}. This macro is +% intended to hold the current definition of \meta{1st}, so \meta{1st} +% can be redefined without loosing information. +% +% \item[0.19] |\lst@CArgX|\meta{characters}|\relax|\meta{macro} +% +% makes \meta{characters} active before calling |\lst@CArg|. +% +% \item[0.21] |\lst@CDef{|\meta{1st}\meta{2nd}\marg{rest}|}|\meta{save 1st}\marg{execute}\marg{pre}\marg{post} +% +% should be used in connection with |\lst@CArg| or |\lst@CArgX|, i.e.~as +% \meta{macro} there. \meta{1st}, \meta{2nd}, and \meta{rest} must be +% active characters and \meta{save 1st} must be an undefined control +% sequence. +% +% Whenever the package reaches the character \meta{1st} (in a listing), +% \meta{execute} is executed. If the package detects the whole string +% \meta{1st}\meta{2nd}\meta{rest}, we additionally execute \meta{pre}, +% then the string, and finally \meta{post}. +% +% \item[0.21] |\lst@CDefX|\meta{1st}\meta{2nd}\marg{rest}\meta{save 1st}\marg{execute}\marg{pre}\marg{post} +% +% Ditto except that we execute \meta{pre} and \meta{post} without the +% original string if we reach \meta{1st}\meta{2nd}\meta{rest}. +% This means that the string is replaced by \meta{pre}\meta{post} (with +% preceding \meta{execute}). +% \end{syntax} +% As the final example, here's the definition of |\lst@DefDelimB|. +% \begin{verbatim} +% \gdef\lst@DefDelimB#1#2#3#4#5#6#7#8{% +% \lst@CDef{#1}#2% +% {#3}% +% {\let\lst@bnext\lst@CArgEmpty +% \lst@ifmode #4\else +% #5% +% \def\lst@bnext{#6{#7}{#8}}% +% \fi +% \lst@bnext}% +% \@empty}\end{verbatim} +% You got it?

Both use |\lst@lostspace|. Lines +% containing only tabulators and spaces should be viewed as empty. In order to +% achieve this, tabulators and spaces at the beginning of a line don't output +% any characters but advance |\lst@lostspace|. Whenever this dimension is +% positive we insert that space before the character string is output. Thus, +% if there are only tabulators and spaces, the line is `empty' since we +% haven't done any output. +% +% We have to do more for flexible columns. Whitespaces can fix the column +% alignment: if the real line is wider than expected, a tabulator is at least +% one space wide; all remaining space fixes the alignment. If there are two or +% more space characters, at least one is printed; the others fix the column +% alignment. +% +% +% \paragraph{Tabulators} +% are processed in three stages. You have already seen the last stage +% |\lst@GotoTabStop|. The other two calculate the necessary width and take care +% of visible tabulators and spaces. +% +% \begin{lstkey}{tabsize} +% We check for a legal argument before saving it.

The point is that \TeX\ seems to use +% the \emph{currently} active catcode table when it writes non-|\immediate| +% |\write|s to file and not the catcodes involved when \emph{reading} the +% characters. +% So a section heading |\L a| was written |\La| if a listing was split on two +% pages since a non-standard catcode table was in use when writing |\La| to +% file, the previously attached catcodes do not matter.

+% \begin{macro}{\lst@MakeCaption}
+% Before defining this macro, we ensure that some other control sequences
+% exist---\lsthelper{Adam~Prugel-Bennett}{2001/02/19}{\abovecaptionskip
+% undefined in slides.cls} reported problems with the slides document class.
+% In particular we allocate above- and belowcaption skip registers and define
+% |\@makecaption|, which is an exact copy of the definition in the article
+% class. To respect the LPPL: you should have a copy of this class on your
+% \TeX\ system or you can obtain a copy from the CTAN, e.g.~from the ftp-server
+% \texttt{ftp.dante.de}.
+%
+% Axel Sommerfeldt proposed a couple of improvements regarding captions and
+% titles. The first is to separate the definitions of the skip registers and
+% |\@makecaption|.
+%    \begin{macrocode}
+\@ifundefined{abovecaptionskip}
+{\newskip\abovecaptionskip
+ \newskip\belowcaptionskip}{}
+\@ifundefined{@makecaption}

+   \else
+     \global \@minipagefalse
+     \hb@xt@\hsize{\hfil\box\@tempboxa\hfil}%
+   \fi
+   \vskip\belowcaptionskip}%
+}{}
+%    \end{macrocode}
+% The introduction of |\fnum@lstlisting| is also due to Axel. Previously the
+% replacement text was used directly in |\lst@MakeCaption|. A |\noindent| has
+% been moved elsewhere and became |\@parboxrestore| after a bug report from
+% \lsthelper{Frank~Mittelbach}{2004/02/13}{Re: Info: Inkompatibilit\"at

+% \lsthelper{Axel~Sommerfeldt}{2004/02/27}{Re: caption + listings + hyperref}
+% for analyzing the bug.
+% We |\refstepcounter| the listing counter if and only if |\lst@@caption| is

+% We make a caption if and only if the caption is not empty and the user
+% requested a caption at |#1| $\in\{\mathtt t,\mathtt b\}$. To disallow
+% pagebreaks between caption (or title) and a listing, we redefine the

+% pagebreaks in front of a `top-caption' and after a `bottom-caption'.
+% Also, the |\ignorespaces| in the |\@makecaption| call is added to match
+% what \LaTeX\ does in |\@caption|; the AMSbook class (and perhaps others)
+% assume this is present and attempt to strip it off when testing for an
+% empty caption, causing a bug noted by \lsthelper{Xiaobo~Peng}{2006/06/29}%

+% The \packagename{float} package defines a generic way for packages to add
+% things (such as chapter names) to all of the lists of floats other than the
+% standard figure and table lists.  Each package that defines a list of
+% floats adds a command to |\float@addtolists|, and then packages (such as
+% the KOMA-script document classes) which wish to add things to all lists of
+% floats can then use it, without needing to be aware of all of the possible
+% lists that could exist.  Thanks to \lsthelper{Markus~Kohm}{-}{2007/02/25}
+% for the suggestion.
+%
+% Unfortunately, \packagename{float} defines this with |\newcommand|; thus,
+% to avoid conflict, we have to redefine it after \packagename{float} is

+% This helper macro adds its argument to the

+% We must append an active backslash and the `end string' to |\lst@arg|. So all

+% an argument. But the EOL character is chr(10)=|^^J| now and not chr(13).

+% \subsubsection{Defining new environments}
+%
+% \begin{macro}{\lstnewenvironment}
+% Now comes the main command. We define undefined environments only. On the
+% parameter text |#1#2#| (in particular the last sharp) see the paragraph
+% following example 20.5 on page 204 of `The \TeX book'.
+%    \begin{macrocode}
+\lst@UserCommand\lstnewenvironment#1#2#{%
+    \@ifundefined{#1}%
+        {\let\lst@arg\@empty
+         \lst@XConvert{#1}\@nil
+         \expandafter\lstnewenvironment@\lst@arg{#1}{#2}}%
+        {\PackageError{Listings}{Environment `#1' already defined}\@eha
+         \@gobbletwo}}
+\def\@tempa#1#2#3{%
+\gdef\lstnewenvironment@##1##2##3##4##5{%
+    \begingroup
+%    \end{macrocode}
+% A lonely `end environment' produces an error.
+%    \begin{macrocode}
+    \global\@namedef{end##2}{\lstenv@Error{##2}}%
+%    \end{macrocode}
+% The `main' environment macro defines the environment name for later use and
+% calls a submacro getting all arguments. We open a group and make EOL active.
+% This ensures |\@ifnextchar[| not to read characters of the listing---it reads
+% the active EOL instead.
+%    \begin{macrocode}
+    \global\@namedef{##2}{\def\lstenv@name{##2}%
+        \begingroup \lst@setcatcodes \catcode\active=\active
+        \csname##2@\endcsname}%
+%    \end{macrocode}
+% The submacro is defined via |\new@command|. We misuse |\l@ngrel@x| to make
+% the definition |\global| and refine \LaTeX's |\@xargdef|.
+%    \begin{macrocode}
+    \let\l@ngrel@x\global
+    \let\@xargdef\lstenv@xargdef
+    \expandafter\new@command\csname##2@\endcsname##3%
+%    \end{macrocode}
+% First we execute |##4|=\meta{begin code}. Then follows the definition of
+% the terminating string (|end{lstlisting}| or |endlstlisting|, for example):
+%    \begin{macrocode}
+        {\lsthk@PreSet ##4%
+         \ifx\@currenvir\lstenv@name
+             \def\lstenv@endstring{#1#2##1#3}%
+         \else
+             \def\lstenv@endstring{#1##1}%
+         \fi
+%    \end{macrocode}
+% We redefine (locally) `end environment' since ending is legal now.
+% Note that the redefinition also works inside a \TeX\ comment line.
+%    \begin{macrocode}
+         \@namedef{end##2}{\lst@DeInit ##5\endgroup
+                          \lst@doendpe \@ignoretrue}%
+%    \end{macrocode}
+% |\lst@doendpe| again removes the indention problem.
+%
+% Finally we start the processing. The |\lst@EndProcessListing| assignment
+% has been moved in front of |\lst@Init| after a bug report by
+% \lsthelper{Andreas~Deininger}{2002/11/11}{Compiling just stops}.
+%    \begin{macrocode}

+%

+% \item[0.19]
+%   |\begin{lstsample}|\marg{point list}\marg{left}\marg{right}
+%
+%   \leavevmode\hspace*{-\leftmargini}|\end{lstsample}|
+%
+%       Roughly speaking all material in between this environment is executed
+%       `on the left side' and typeset verbatim on the right. \meta{left} is
+%       executed before the left side is typeset, and similarly \meta{right}
+%       before the right-hand side.
+%
+%       \meta{point list} is used as argument to the \keyname{point} key.
+%       This is a special key used to highlight the keys in the examples.
+%
+% \item[1.0]
+%   |\begin{lstxsample}|\marg{point list}
+%
+%   \leavevmode\hspace*{-\leftmargini}|\end{lstxsample}|
+%
+%       The material in between is (a) added to the left side of the next
+%       \texttt{lstsample} environment and (b) typeset verbatim using the
+%       whole line width.
+%
+% \item[0.21] |\newdocenvironment|\marg{name}\marg{short name}\marg{begin code}\marg{end code}
+%
+%       The \meta{name} environment can be used in the same way as `macro'.
+%       The provided(!) definitions
+%           |\Print|\meta{short name}|Name|
+%       and |\SpecialMain|\meta{short name}|Index|
+%       control printing in the margin and indexing as the defaults
+%       |\PrintMacroName| and |\SpecialMainIndex| do.
+%
+%       This command is used to define the `aspect' and `lstkey' environments.
+%
+%\item[0.21] \texttt{macroargs} environment
+%
+%       This `enumerate' environment uses as labels `|#1| =', `|#2| =',
+%       and so on.
+%
+% \item \texttt{TODO} environment
+% \item \texttt{ALTERNATIVE} environment
+% \item \texttt{REMOVED} environment
+% \item \texttt{OLDDEF} environment
+%
+%       These environments enclose comments on `to do's', alternatives and
+%       removed or old definitions.
+%
+% \item[0.21] |\lstscanlanguages|\meta{list macro}\marg{input files}\marg{don't input}
+%
+%       scans \marg{input files}$\setminus$\marg{don't input} for language
+%       definitions. The available languages are stored in \meta{list macro}
+%       using the form \meta{language}|(|\meta{dialtect}|),|.
+%
+% \item[0.21] |\lstprintlanguages|\meta{list macro}
+%
+%       prints the languages in two column format.

+% Again, the main thing is a special working procedure. First we extract the
+% contents of |\lst@token| and get a free macro name for this current character
+% string (using prefix |lstHR@| and a number as suffix). Then we make this
+% free macro equivalent to |\@empty|, so it is not used the next time.
+%    \begin{macrocode}
+\lst@InstallKeywords{h}{hyperref}{}\relax{}
+    {\begingroup

+     \global\expandafter\let\lst@freemacro\@empty
+%    \end{macrocode}
+% |\@tempcnta| is the suffix of the free macro. We use it here to refer to
+% the last occurence of the same string. To do this, we redefine the output
+% macro |\lst@alloverstyle| to set an anchor \ldots
+%    \begin{macrocode}
+     \@tempcntb\@tempcnta \advance\@tempcntb\m@ne
+     \edef\lst@alloverstyle##1{%

+%    \end{macrocode}
+% \ldots\space and a link to the last occurence (if there is any).

+% \section{History}
+% \begingroup\small
+% Only major changes are listed here. Introductory version numbers of commands
+% and keys are in the sources of the guides, which makes this history fairly
+% short.
+% \renewcommand\labelitemi{--}
+% \begin{itemize}
+% \item[0.1] from 1996/03/09
+%   \item test version to look whether package is possible or not

+%   \item load on demand: language specific macros moved to driver files
+%   \item comments are declared now and not implemented for each language again
+%         (this makes the \TeX\ sources easier to read)
+% \item[0.14] from 1997/02/18
+%   \item User's guide rewritten, Implementation guide uses macro environment
+%   \item (non) case sensitivity implemented and multiple string types,

+%\fi
+% \item[0.15] from 1997/04/18
+%\iffalse

+%\fi
+%   \item listing environment rewritten
+% \item[0.17] from 1997/09/29
+%\iffalse
+%   \item |\spreadlisting| works correct now (e.g.~page numbers don't move right)
+%\fi
+%   \item speed up things (quick `if parameter empty', all |\long| except one
+%         removed, faster \verb!\lst@GotoNextTabStop!, etc.)
+%   \item improved alignment of wide other characters (e.g.~$==$)
+%\iffalse
+%   \item many new languages: Ada, Algol, Cobol, Comal 80, Elan, Fortran 77,
+%         Lisp, Logo, Matlab, Oberon, Perl, PL/I, Simula, SQL, \TeX
+%\fi
+% \item[pre-0.18] from 1998/03/24 (unpublished)
+%\iffalse
+%   \item bug concerning |\labelstyle| (becomes \keyname{numberstyle}) removed

+%\fi
+%   \item experimental implementation of character classes
+% \item[0.19] from 1998/11/09

+% \item[0.21] 2000/08/23
+%   \item completely new User's guide
+%   \item experimental format definitions
+%   \item keyword classes replaced by families
+%   \item dynamic modes
+% \item[1.0$\beta$] 2001/09/21
+%   \item key names synchronized with \packagename{fancyvrb}
+%   \item \aspectname{frames} aspect extended

-% Remark: "isQuery" is not real OCL, but a important attribute of the

-% The dialect called \texttt{OMG} is a very spare version. If you use

-% Second order keywords are the operation which are defined for type
-% Boolean (see pages 7-34/35 of the OMG standard) and the let-operation
-% (in principle these are the infix operations):
-%    \begin{macrocode}
-    ndkeywords={or,xor,and,not,implies,if,then,else,endif},%
-%    \end{macrocode} 
-% Third order keywords are the basic data types as declared in section 7.4 of

+%
+% Comsol Multiphysics (Prior to version 3.2 known as Femlab) can be used 
+% standalone or as an extension to MatLab.  This definition is due to
+% \lstthanks{Martin~Heller}{-}{2006/05/10}.
+%
+% Unfortunately, there is a conflict in that Comsol is case-insensitive,
+% whereas Matlab is case-sensitive; \textsf{listings} does not
+% currently support different case-sensitivities in the same listing.

+%               \textbf{OMG Unified Modeling Language Specification};
+%               {\copyright} 1999 OMG;
+%               Available at \texttt{ftp://ftp.omg.org/pub/docs/ad/99-06-08.pdf}.

+% First we define are very decorative style. In the OMG standard only the
+% boolean (infix (?)) operations are highlighted, but I think all OCL-defined
+% operations should be highlighted, because they are \emph{guaranteed} to be
+% side-effect-free (in OCL only side effect free evaluations or path
+% expressions are allowed).
+%    \begin{macrocode}
+\lst@definelanguage[decorative]{OCL}[OMG]{OCL}
+  {otherkeywords={@pre},%
+   morendkeywords={name,attributes,associatoinEnds,operations,%
+      supertypes,allSupertypes,allInstances,oclIsKindOf,oclIsTypeOf,%

+      first,last,true,false,isQuery}%
+  }%
+%    \end{macrocode} 
+% Remark: "isQuery" is not real OCL, but a important attribute of the
+% underlying UML model.
+%
+% The dialect called \texttt{OMG} is a very spare version. If you use
+% this variant with bold style for first and second order keywords you
+% get the look and feel of the OMG standard. First order keywords are the
+% OCL context declarations (see section 7.3 of the OMG standard):
+%    \begin{macrocode}
+\lst@definelanguage[OMG]{OCL}%
+    {morekeywords={context,pre,inv,post},%
+%    \end{macrocode} 
+% Second order keywords are the operation which are defined for type
+% Boolean (see pages 7-34/35 of the OMG standard) and the let-operation
+% (in principle these are the infix operations):
+%    \begin{macrocode}
+    ndkeywords={or,xor,and,not,implies,if,then,else,endif},%
+%    \end{macrocode} 
+% Third order keywords are the basic data types as declared in section 7.4 of
+% the OMG standard:
+%    \begin{macrocode}
+    morekeywords=[3]{Boolean,Integer,Real,String,Set,Sequence,Bag,%
+       OclType,OclAny,OclExpression,Enumeration,Collection,},%
+    sensitive=t,%
+    morecomment=[l]--,%
+    morestring=[d]'%
+   }[keywords,comments,strings]%
+%    \end{macrocode}
+% After a bug report by \lsthelper{Martin~S\"u\ss kraut}{Edon.Myder@web.de}
+% {2003/01/30}{morerdkeywords doesn't exist any more} \texttt{morerdkeywords}
+% has been changed to the correct optional argument \texttt{[3]}.

+%
+% \lstthanks{Christian~Kaiser}{chk@combit.net}{2003/02/05} provided the initial
+% definition. \lstthanks{Xavier~Noria}{fxn@hashref.com}{2004/01/11} replaced
+% the keywords with the keywords from the at the time of writing current
+% stable Ruby version.  An erroneous string delimiter was removed following
+% a bug reported on comp.text.tex on 2006/09/01.
+%
+% Ruby supports string delimiters of the form \verb|%q!...!|, where \verb|!|
+% can be any character, or can be matched braces or parentheses or brackets.
+% The included string definitions include most of the common variants, but are
+% of course not comprehensive.

+% Tcl/Tk is a very dynamic language. A statical analysis might not be
+% adequate. Nevertheless the following definitions produce the desired
+% result for my programs with a minimum of ``misses''.
