+checklistings
+=============
+
+By [Timothy Bourke](http://www.tbrk.org)
+and [Marc Pouzet](http://www.di.ens.fr/~pouzet).
+
+User manuals and papers about programming languages usually contain many 
+code samples, often with accompanying compiler messages giving the types 
+of declarations or error messages explaining why certain declarations are 
+invalid.
+
+The `checklistings` package augments the
+[fancyvrb](http://www.ctan.org/pkg/fancyvrb) and
+[listings](http://www.ctan.org/pkg/listings) packages for including source
+code in LaTeX documents with a way to pass the source code through a
+compiler and also include the resulting messages in the document.
+
+The motivation is to check the code samples in a document for syntax and
+typing errors and to facilitate the inclusion of inferred types and compiler
+warnings or errors in a text. This package is intentionally very lightweight
+and unlike packages like [python](http://www.ctan.org/pkg/python) it is not
+intended for interacting with an interpretor or including the execution
+traces of code. While `checklistings` does not focus on a specific
+programming language, it is designed to work well with ML-like languages.
+
+Using the package involves three elements:
+
+1. The declaration `\usepackage{checklistings}`.
+2. The verbatim environment `\begin{chklisting}...\end{chklisting}`.
+3. The shell script `checklistings.sh`.
+
+In a first pass, `latex`/`pdflatex` outputs code samples into files.
+The second pass is performed by `checklistings.sh` which passes each file
+through a compiler to generate corresponding output files.
+In a third pass, `latex`/`pdflatex` reads from the generated files to
+incorporate the results into the document.
+
+A `checklistings.hva` file is provided for interoperability with
+[HeVeA](http://hevea.inria.fr).
+
+The `checklistings` package may be distributed and/or modified under the
+conditions of the
+[LaTeX Project Public License](http://www.latex-project.org/lppl.txt),
+either version 1.2 of this license or (at your option) any later version.
+
+Please send comments, suggestions, and bug reports (with version number and
+the keyword "checklistings" in the subject of the message) to
+<tim@tbrk.org>. Please keep in mind that we prefer to keep `checklistings`
+simple and lightweight rather than to incorporate many different
+configuration and customization options. The source code is hosted on 
+[GitHub](https://github.com/tbrk/checklistings).
+
+This package was developed within the
+[PARKAS](http://www.di.ens.fr/ParkasTeam.html) at
+[Inria](http://www.inria.fr) and the [ENS](http://www.di.ens.fr).

+%% HeVeA support for checklistings.
+%%
+%% Limitations / caveats
+%%
+%% * checklistings.hva requires all the intermediate generated by latex and
+%%   checklistings.sh (*.<ext>, *.tex, *.msg, *.err).
+%%
+%% * The options 'codestyle', 'msgstyle', 'errstyle', 'codelst', 'msglst',
+%%   and 'errlst' cannot be set as in LaTeX, e.g.,
+%%	\checklistings{codelst={language=caml}}
+%%   Since HeVeA eliminates the grouping braces and passes 'language' to
+%%   the handler for 'codelst' (rather than 'language=caml').
+%%
+%%   One workaround is to \usepackage{hevea} and use \ifhevea to select
+%%   the most appropriate of the two forms.
+%%
+%% * fancyvrb and the package options codestyle, msgstyle, and errstyle are
+%%   not supported.
+%%   Alternative 1: use the codelst, msglst, and errlst options.
+%%   Alternative 2: use css for formatting code, messages, and errors.
+%%
+%% * Non-empty labels in the arguments of \chklistingmsg and
+%%   \chklistingerr are not supported.

+% \section{Introduction}
+%
+% User manuals and papers about programming languages usually contain many 
+% code samples, often with accompanying compiler messages giving the types 
+% of declarations or error messages explaining why certain declarations are 
+% invalid.
+% This package extends 
+% |fancyvrb|\footnote{\url{http://www.ctan.org/pkg/fancyvrb}} and 
+% |listings|\footnote{\url{http://www.ctan.org/pkg/listings}}, which are 
+% ideal for displaying code, with a way to pass code samples through a 
+% compiler and include the resulting messages in a \LaTeX{} document.
+% The motivation is to check the code samples in a document for syntax and 
+% typing errors and to facilitate the inclusion of inferred types and 
+% compiler warnings or errors in a text.
+% This package is intentionally very lightweight and unlike packages like 
+% |python|,\footnote{\url{http://www.ctan.org/pkg/python}} it is not 
+% intended for interacting with an interpretor or including the execution 
+% traces of code.
+% While it does not focus on a specific programming language, it is designed 
+% to work well with ML-like languages.
+%
+% As an example, the text at left below is generated by the \LaTeX{} code at 
+% right:
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{LTXexample}
+Code samples are included
+verbatim and the results of
+compilation can be included
+automatically:

+let inc x = x + 1
+let y = inc 3
+\end{chklisting}
+\end{LTXexample}
+% \iffalse
+%</example>
+% \fi
+%
+% A first pass through |latex| generates both a |.chkl| file,
+% with parameters for the compiler, and an |.ml| file containing the source 
+% code (i.e., the two lines in the example above).
+% Running the |checklistings.sh| script processes these files to produce a 
+% |.tex| file with the results of compilation.
+% A second pass through |latex| updates the compiler message.
+%
+% \noindent
+% It is possible to continue examples and to label them (to be continued at 
+% some later point):
+% \iffalse
+%<*example>
+% \fi
+\begin{LTXexample}[pos=b]
+These definitions follow on from the previous ones:
+\begin{chklisting}[continue,withresult,label=early]
+let z = y + inc y
+\end{chklisting}
+\end{LTXexample}
+% \iffalse
+%</example>
+% \fi
+%
+% \bigskip\noindent
+% Examples need not necessarily succeed:
+% \iffalse
+%<*example>
+% \fi
+\begin{LTXexample}[pos=b]
+This code does not compile:
+\begin{chklisting}[continue,fail,withresult,skipone]
+let u = 3
+let w = u + "four"
+\end{chklisting}
+\end{LTXexample}
+% \iffalse
+%</example>
+% \fi
+% Note that the line number in the error message is 1 even though the 
+% |continue| option added a line to include the previous definitions and the 
+% |skipone| option hid the |let u = 3| line.
+% The |checklistings.sh| script performs this adjustment by looking for the 
+% regular expression `|line  *[0-9][0-9]*|' and decrementing the number 
+% appropriately.
+% This approach is simple and effective but obviously not foolproof.
+% Some manual tuning of the script may be required for correct results.
+%
+% \section{Use}\label{sec:use}
+%
+% Using the package involves three elements:
+% \begin{enumerate}
+%
+% \item
+% The declaration \verb|\usepackage{checklistings}|.\\
+% \refsec{rvpkg} describes the options for configuring package behaviour.
+%
+% \item
+% The environment \verb|chklisting|.\\
+% This environment is used like any other verbatim environment.
+% \refsec{rvenv} describes options that may be given to control its 
+% behaviour.
+%
+% \item
+% The script \verb|checklistings.sh|.\\
+% Running this script passes the contents of each \verb|chklisting| 
+% environment through a compiler or interpreter and copies the resulting 
+% output into a file.
+%
+% \end{enumerate}
+%
+% Additionally, the file \verb|checklistings.hva| can be used to incorporate 
+% the output of |checklistings| in HTML documents generated by 
+% HeVeA.\footnote{\url{http://hevea.inria.fr}}
+%
+% \subsection{Package options}\label{sec:rvpkg}
+%
+% \DescribeMacro{\checklistings}
+% Package options are either given as optional arguments to 
+% \verb|\usepackage| or via one or more calls to \verb|\checklistings|.
+% The advantage of the latter is that macros are not expanded (for a 
+% detailed explanation see the documentation for 
+% |kvoptions|,\footnote{\url{http://www.ctan.org/pkg/kvoptions}} Section 
+% 4.1, \emph{Package kvoptions-patch}).
+% Options are passed as a comma separated list of \meta{key}|=|\meta{value} 
+% pairs and single \meta{key}s.
+%
+% There are three classes of options: options controlling the default 
+% behaviour of \verb|chklisting|, options for configuring the 
+% \verb|checklistings.sh| script, and options controlling the display of
+% code and results.
+%
+% \subsubsection{Behavioural options}
+%
+% These options control the default behaviour of the \verb|chklisting| 
+% environment.
+%
+% \begin{longtable}{@{}>{\ttfamily}lp{75mm}>{\ttfamily}l@{}}
+% \parbox{15mm}{option} & description & \parbox{25mm}{default}\\\hline
+% withresult
+% & Automatically show compilation results.
+% & false
+% \\
+% skipone
+% & Do not display the first line of code (see the description under the 
+% |chklisting| environment).
+% &
+% false
+% \\
+% skiptwo
+% & Do not display the first two lines of code (see the description under 
+% the |chklisting| environment).
+% &
+% false
+% \\
+% hideproblems
+% & Globally disable the display of failure messages (within a red box) when 
+% compilation fails or succeeds unexpectedly.
+% &
+% false
+% \\
+% \end{longtable}
+%
+% \subsubsection{Configuring compilation}\label{sec:compileconfig}
+%
+% These options are used for naming and placing the files generated by 
+% \verb|chklisting| environments.
+% They are passed to the \verb|checklistings.sh| script and thus control
+% its behaviour.
+%
+% \makeatletter
+% \begin{longtable}{@{}>{\ttfamily}lp{75mm}>{\ttfamily}l@{}}
+% \parbox{15mm}{option} & description & \parbox{25mm}{default}\\\hline
+% prefix
+% & Prefix for naming source files.
+%   It must not contain underscores (\verb|_|).
+% & \CHKL@prefix
+% \\
+% ext
+% & Extension of source files.
+% & \CHKL@ext
+% \\
+% subdir
+% & If defined, source files are created in the given subdirectory, which 
+% must already exist.
+% A final slash (\verb|/|) should not be given.
+% The name must not contain underscores (\verb|_|).
+% & \CHKL@subdir
+% \\
+% prompt
+% & The prompt displayed by |\chklistingcmd|.
+% & \CHKL@prompt
+% \\
+% compiler
+% & Path of the compiler to execute.
+% & \CHKL@compiler
+% \\
+% compilerflags
+% & Flags passed to the compiler.
+% These are not revealed by |\chklistingcmd|.
+% & \CHKL@compilerflags
+% \\
+% lastflags
+% & Flags passed to the compiler before the main source file, that is, the 
+% last one given.
+% & \CHKL@lastflags
+% \\
+% includecmd
+% & The source language command for importing the definitions of another 
+% file.
+% & \CHKL@includecmd
+% \\
+% html
+% & The path of a program that renders source code as html.
+% This value can be useful when using HeVeA to produce web pages from 
+% \LaTeX{} documents.
+% In any case, it is optional.
+% & \CHKL@html
+% \end{longtable}
+% \makeatother
+%
+% Each \verb|chklisting| environment is assigned a number $n$, from zero, 
+% and its contents are written to the file:
+% \meta{subdir}|/|\meta{prefix}\meta{n}|.|\meta{ext},
+% where \meta{n} is zero-padded to four characters.
+% For example, by default, the fourth environment is written to the file 
+% \verb|chklisting0003.ml| in the current directory.
+%
+% Source lines are added for each dependency, and those files are compiled 
+% using the \meta{compiler}, \meta{compilerflags}, and \meta{lastflags} 
+% options.
+% For example, if the fourth environment depends on the first and the 
+% second, a line is added:
+% \begin{center}
+% \meta{includecmd} |Withopen0000| \meta{includecmd} |Withopen0001|,
+% \end{center}
+% where \verb|Withopen| is the prefix used for such augmented files, and the 
+% compiler is invoked with:\\
+% \begin{center}
+% \begin{tabular}{ll}
+% \meta{compiler}
+%   & \meta{compilerflags}\ \ |Withopen0000|\ \ |Withopen0001| \\
+%   & \meta{lastflags}\ \ |Withopen0003|
+% \end{tabular}
+% \end{center}
+%
+% \subsubsection{Controlling the display}
+%
+% This package exploits the display options given by the |fancyvrb| package.
+%
+% \begin{longtable}{@{}>{\ttfamily}lp{75mm}>{\ttfamily}l@{}}
+% \parbox{15mm}{option} & description & \parbox{25mm}{default}\\\hline
+% codestyle
+% & |fancyvrb| options for code
+% & \\
+% msgstyle
+% & |fancyvrb| options for compiler messages
+% & formatcom=\string\em
+% \\
+% errstyle
+% & |fancyvrb| options for error messages
+% & formatcom=\string\em
+% \\
+% codelst
+% & |listings| options for source code, passed with |\lstset|. When this 
+% option is not empty, |fancyvrb=true| is included automatically.
+% \\
+% msglst
+% & As for |codelst|, but applied to compiler messages.
+% \\
+% errlst
+% & As for |codelst|, but applied to error messages.
+% \\
+% \end{longtable}
+%
+% Other options are passed directly through to the |fancyvrb| package and 
+% applied to all |chklisting| code blocks (but not to messages or errors).
+% For example, \verb|frame=single|.
+% These options must typically be set using |\checklistings|, since they 
+% will usually contain commands that should not be expanded immediately 
+% (like |\em| or |\bf|).
+%
+% \subsection{The \texttt{chklisting} environment}\label{sec:rvenv}
+%
+% \DescribeEnv{chklisting}
+% As an optional argument, this environment takes a comma separated list of 
+% \meta{key}|=|\meta{value} and single \meta{key}s.
+%
+% \begin{longtable}{@{}>{\ttfamily}lp{100mm}}
+% \parbox{15mm}{option} & description \\\hline
+% fail
+% & This code is expected to fail; an error is reported if it succeeds.
+% \\
+% continue
+% & This code is continued from the previous |chklisting| environment; all 
+% of the definitions available there are imported.
+% \\
+% label
+% & Label this code for later inclusion.
+% \\
+% include
+% & All of the definitions available after the environment with the given 
+% label are imported.
+% \\
+% withresult
+% & The result of compiling the code is displayed (see also 
+% |\chklistingmsg| and |\chklistingerr|).
+% This is normally either the types of declared values or the results of 
+% evaluation.
+% For environments marked |fail|, it will be an error message.
+% \\
+% withoutresult
+% & The result of compiling code is not displayed automatically.
+%   This is the default behaviour, but it can be overridden by the package 
+%   options.
+% \\
+% hide
+% & The code is not displayed, but it is still compiled, compiler messages 
+% are still displayed (if |withresult| is active), and definitions are still 
+% available for continuation (|continue|), labelling (|label|), and later 
+% inclusion (|include|).
+% \\
+% skipone
+% & Do not display the first line of the code.
+%   This line is still sent to the compiler and may thus be used to open 
+%   other modules, or to pass execution options (via comments).
+% \\
+% skiptwo
+% & As pre the previous option, but two lines are skipped.
+% \\
+% skipnone
+% & Do not skip any lines; this option overrides any package-level skip 
+% setting.
+% \\
+% hideproblems
+% & Do not display an error message within the document when compilation 
+% fails or succeeds unexpectedly.
+% \\
+% showproblems
+% & Display an error message within the document when compilation fails or 
+% succeeds unexpectedly.
+% This is the default behaviour unless the |hideproblems| package option was 
+% set.
+% \\
+% \end{longtable}
+%
+% The results of compiling the code of a |chklisting| environment are made 
+% available in the following macros until the next |chklisting| which will 
+% redefine them.
+% \begin{description}
+%
+% \item[\texttt{\string\chklistingcmd}]
+% \DescribeMacro{\chklistingcmd}
+% contains an idealised version of the command line used to compile the code 
+% sample.
+% It includes the |prompt|, the basename of |compiler|, and |lastflags|, but 
+% not |compilerflags| or the list of included files.
+% Furthermore, the |subdir| and serial number are removed from the filename 
+% of the code sample, which becomes simply \meta{prefix}|.|\meta{ext}.
+%
+% \item[\texttt{\string\chklistingmsg\marg{label}}]
+% \DescribeMacro{\chklistingmsg}: inserts the verbatim text emitted by the 
+% compiler, provided compilation succeeded, for the |chklisting| 
+% environment labelled \meta{label}.
+% When \meta{label} is left empty, the message for the last environment is 
+% inserted.
+% It should not be used after environments marked |fail|.
+%
+% \item[\texttt{\string\chklistingerr\marg{label}}]
+% \DescribeMacro{\chklistingerr}: inserts the verbatim text emitted by the 
+% compiler, provided compilation failed, for the |chklisting| environment 
+% labelled \meta{label}.
+% When \meta{label} is left empty, the message for the last environment is 
+% inserted.
+% It should only be used after environments marked |fail|.
+% \end{description}
+%
+% \subsection{The \texttt{checklistings.sh} script}\label{sec:rvsh}
+%
+% Processing a document that uses the |checklistings| package produces a 
+% |.chkl| file containing compiler options and a list of source files 
+% together with their interdependencies.
+% The |checklistings.sh| script processes |.chkl| files by executing the 
+% specified compiler against each listed source file 
+% \meta{subdir}|/|\meta{prefix}\meta{n}|.|\meta{ext} and copying the 
+% results---the command-line used, whether it succeeded or failed, the 
+% messages on |stdout|, and the messages on |stderr|---into a corresponding 
+% file, \meta{subdir}|/|\meta{prefix}\meta{n}|.tex|, for inclusion in the 
+% original document.
+%
+% The \verb|checklistings.sh| script is written for the Bourne shell 
+% (\verb|sh|).
+% It takes a list of |.chkl| files as arguments (with or without the 
+% exentions), but if none are given it processes all such files in the 
+% current working directory.
+%
+% The compilation options specified within a \LaTeX{} source file, see
+% \refsec{compileconfig}, can be manually overridden by processing a |.chkl| 
+% file, before any others, containing a `|lock|' directive, for example:
+% |lock compiler=/usr/local/bin/ocamlc|.
+% This feature is useful when working with others to develop the compiler 
+% being documented.
+%

+%
+% \section{Remarks}
+%
+% \subsection{Known limitations}
+%
+% The package and script have some known limitations.
+% \begin{itemize}
+% 
+% \item
+% Line numbers in error messages may not correspond correctly with the line 
+% numbers of sample files, due to either the |skip*| options, or because of 
+% lines added to import code.
+%
+% \item
+% The system has been designed to work with ML-style compilers.
+% It has not been tested with other compilers and interpreters.
+% Please contact \url{tim@tbrk.org} if you would like to support other 
+% systems.
+% Patches are most welcome, but the intent is to keep this package 
+% relatively simple rather than to try to do everything.
+%
+% \item
+% Multiple languages in a single document are not supported.
+%
+% \item
+% Care must be taken when using |checklistings| with the overlays of the 
+% Beamer package.
+% In particular, |chklisting| environment commands are to be avoided within 
+% commands that completely omit material from slides, like |only|, |alt|, or 
+% |temporal|, or with `closed' overlay specifications, like |2| or |1-3|.
+% As these commands do not execute the material, the environment sequence 
+% numbers do not increase monotonically, and the compilation results may not 
+% be properly synchronized with the verbatim text.
+% Commands that only hide material, or that introduce it successively, like 
+% |uncover| or |visible|, or `open' overlay specifications, like |2-|, 
+% should function as expected.
+%
+% \end{itemize}
+%
+% \section{Implementation}
+%
+% All internal macros have names of the form |\CHKL@|\meta{name}.
+%
+% \begin{macro}{\chklisting}
+% Generate the sequence of source code identifiers used in per-environment 
+% filenames and to manage dependencies.
+% If |beamer| is being used, reset the counter on each overlay to avoid 
+% generating multiple output files for the same program.
+%    \begin{macrocode}
+\newcounter{chklisting}
+\ifdefined\resetcounteronoverlays
+\resetcounteronoverlays{chklisting}
+\fi
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ifCHKL@fileexists}
+% An internal boolean variable for remembering whether an input |.tex| file, 
+% corresponding to the compilation of source code, was found.
+%    \begin{macrocode}
+\newif\ifCHKL@fileexists
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Package Options}
+%
+% The package options are processed using the |kvoptions| package.
+%
+% \begin{macro}{\CHKL@pkg@verbopts}
+% This list accumulates package-level options for the |verbatim| 
+% environments.
+%    \begin{macrocode}
+\def\CHKL@pkg@verbopts{}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\CHKL@pkg@globalskip}
+% Defines the number of lines to be skipped when displaying a code sample as 
+% defined by the global options |skipone| and |skiptwo|.
+%    \begin{macrocode}
+\def\CHKL@pkg@globalskip{0}
+%    \end{macrocode}
+% \end{macro}
+%
+% \noindent
+% Declare the package options and their default values:

+%    \end{macrocode}
+%
+% \begin{macro}{\checklistings}
+% This macro offers another way of setting package options with the 
+% advantage that values are not expanded.
+%    \begin{macrocode}
+\def\checklistings{\kvsetkeys{CHKL}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Logging Files to be Processed}
+%
+% Several definitions and commands are used to create and write to the 
+% |.chkl| file.
+%
+% \begin{macro}{\CHKL@samplefile}
+% The file generated when a \LaTeX{} document that uses the |checklistings| 
+% package is processed.
+%    \begin{macrocode}
+\newwrite\CHKL@samplefile
+\openout\CHKL@samplefile=\jobname.chkl
+\AtEndDocument{\closeout\CHKL@samplefile}
+%    \end{macrocode}
+% \end{macro}
+%
+% Package options are logged to the file.
+%    \begin{macrocode}
+\write\CHKL@samplefile{subdir=\CHKL@subdir/}
+\write\CHKL@samplefile{prefix=\CHKL@prefix}
+\write\CHKL@samplefile{ext=\CHKL@ext}

+\write\CHKL@samplefile{compilerflags=\CHKL@compilerflags}
+\write\CHKL@samplefile{lastflags=\CHKL@lastflags}
+\write\CHKL@samplefile{includecmd=\CHKL@includecmd}
+\write\CHKL@samplefile{htmlfilter=\CHKL@html}
+%    \end{macrocode}
+%
+% \begin{macro}{\CHKL@logsample}
+% An entry is logged for each |chklisting| environment.
+% It contains the sequence number for the example, followed by a colon, an 
+% ordered list of other sample files to import, and the page and line 
+% numbers (to include in error messages).
+%    \begin{macrocode}
+\DeclareRobustCommand{\CHKL@logsample}[2]{%
+  \edef\CHKL@tolog{#1:#2 [page=\noexpand\thepage] [line=\the\inputlineno]}%
+  \expandafter\write\expandafter\CHKL@samplefile\expandafter{\CHKL@tolog}%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Insertion of Compilation Results}
+%
+% Several macros are defined for use by the |checklistings.sh| script (and
+% any similar program).
+% These macros are called from within the |.tex| file generated for each 
+% |chklisting| environment.
+%
+% \begin{macro}{\ifchklisting}
+% A successful compilation is signalled by |\chklistingtrue|, and a failed 
+% compilation by |\chklistingfalse|.
+%    \begin{macrocode}
+\newif\ifchklisting
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\setchklistingcmd}
+% The command used to compile a sample is recorded by |\setchklistingcmd| 
+% which (re)defines the internal |\CHKL@prompt| value.
+%    \begin{macrocode}
+\DeclareRobustCommand{\setchklistingcmd}[1]{%
+    \global\def\chklistingcmd{\emph{\CHKL@prompt{#1}}}}
+%    \end{macrocode}
+% \end{macro}
+
+% \begin{environment}{ChkListingMsg}
+% Normal compiler messages (written on |stdout|) should be communicated 
+% between |\begin{ChkListingMsg}| and |\end{ChkListingMsg}|.
+% This verbatim text is saved using the |SaveVerbatim| feature of 
+% |fancyvrb|.
+%    \begin{macrocode}
+\def\ChkListingMsg{\FV@Environment{}{ChkListingMsg}}
+\def\FVB@ChkListingMsg{\FVB@SaveVerbatim{ChkListingMsg}}
+\let\FVE@ChkListingMsg\FVE@SaveVerbatim
+\DefineVerbatimEnvironment{ChkListingMsg}{ChkListingMsg}{}
+%    \end{macrocode}
+% \end{environment}
+
+% \begin{environment}{ChkListingErr}
+% Compiler error messages (usually written on |stderr|) should be 
+% communicated between |\begin{ChkListingErr}| and |\end{ChkListingErr}|.
+% This verbatim text is saved using the |SaveVerbatim| feature of 
+% |fancyvrb|.
+%    \begin{macrocode}
+\def\ChkListingErr{\FV@Environment{}{ChkListingErr}}
+\def\FVB@ChkListingErr{\FVB@SaveVerbatim{ChkListingErr}}
+\let\FVE@ChkListingErr\FVE@SaveVerbatim
+\DefineVerbatimEnvironment{ChkListingErr}{ChkListingErr}{}
+%    \end{macrocode}
+% \end{environment}
+
+% \begin{macro}{\chklistingfile}
+% This is the filename used by |checklistings.sh| to refer to the file 
+% containing sample code when |\setchklistingcmd| is called.
+%    \begin{macrocode}
+\DeclareRobustCommand{\chklistingfile}{\CHKL@prefix\CHKL@ext}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Main Environment}
+%
+% Several auxiliary definitions are needed to track per-environment 
+% configuration options.
+%
+% \begin{macro}{\ifCHKL@shouldfail}
+% This boolean variable records whether sample code is expected to fail.
+%    \begin{macrocode}
+\newif\ifCHKL@shouldfail
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\ifCHKL@showcode}
+% This boolean variable records whether the compilation result should be 
+% shown.
+%    \begin{macrocode}
+\newif\ifCHKL@showcode
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\CHKL@skip}
+% Defines the number of lines to be skipped when displaying a code sample.
+% It defaults to the value of |\CHKL@pkg@globalskip|, but may be altered by 
+% the environment options |skipone| and |skiptwo|.
+% This value is only used to generate the |skip=| field in the |.chkl| file.
+% The actual skipping is done by the |firstline| option of |verbopts|.
+% \begin{macrocode}
+\def\CHKL@skip{0}
+%    \end{macrocode}
+% \end{macro}
+%
+% The |keyval| package\footnote{\url{http://www.ctan.org/pkg/keyval}} is 
+% used to parse environment options.
+% The following macros setup parameters used by the |chklisting| 
+% environment.
+%
+% \begin{macro}{\CHKL@continue}
+% \begin{macro}{\CHKL@precontinue}
+% These two macros hold lists of source code identifiers: 
+% |\CHKL@precontinue| tracks the dependencies of the previous |chklisting| 
+% environment and |\CHKL@continue| tracks those of the current one.
+% The |continue| option appends the previous dependencies onto the list of 
+% current ones.
+% The dependencies used at each labelled environment are remembered in 
+% |\RBRB@deps|\meta{label}.
+% The |include| option causes them to be added to the list of current 
+% dependencies.
+%
+%    \begin{macrocode}
+\edef\CHKL@precontinue{}
+\define@key{CHKL@envkeys}{continue}[]{\edef\CHKL@continue{\CHKL@precontinue}}
+\define@key{CHKL@envkeys}{include}{%
+  \edef\CHKL@continue{\CHKL@continue\space\@ifundefined{CHKL@deps@#1}%
+    {#1}{\csname CHKL@deps@#1\endcsname}}}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+%    \begin{macrocode}
+\define@key{CHKL@envkeys}{fail}[]{\CHKL@shouldfailtrue}
+\define@key{CHKL@envkeys}{label}{\edef\CHKL@label{#1}}
+\define@key{CHKL@envkeys}{skipnone}[]{%
+  \edef\CHKL@skip{0}\edef\CHKL@verbopts{\CHKL@verbopts,firstline=1}}
+\define@key{CHKL@envkeys}{skipone}[]{%

+\define@key{CHKL@envkeys}{showproblems}[]{\CHKL@showproblemstrue}
+\define@key{CHKL@envkeys}{hideproblems}[]{\CHKL@showproblemsfalse}
+%    \end{macrocode}
+%
+% \begin{macro}{\chklistingmsg}
+% This macro takes a single argument \meta{label}.
+% It first configures the |listings| and |fancyvrb| packages with the 
+% current display options.
+% It then checks the |fancyvrb| saved text namespace 
+% (`\texttt{FV@SV@\ldots}') for an entry named `\texttt{\ldots 
+% CHKL@MSG@\meta{label}}'.
+% If found, the associated verbatim text is inserted via the |\UseVerbatim| 
+% feature of |fancyvrb|, otherwise an error message is inserted.
+% In the latter case, we prefer not to fail outright, because the user may 
+% not yet have had the chance to run the compiler on the extracted code, in 
+% which case the log will already contain warnings from |chklisting|.

+% \item
+% It uses the listings package to write the code to a file,

+%
+% The |listings| package allows the definition of custom verbatim
