+\begin{abstract}
+  This package provides the \LaTeX\ environment \verb|listing|, an
+  alternative to the built-in \verb|verbatim| environment.  The
+  \verb|listing| environment is specially taylored for including
+  listings of computer program source code into documents.  The main
+  advantages over the original \verb|verbatim| environment are that
+  \verb|listing| environments automatically fix leading white-space
+  so that the environment and program listing can be indented with
+  the rest of the \LaTeX\ source code and that \verb|listing|
+  environments can easily be customised and extended.
+\end{abstract}
+
+\tableofcontents
+
+\section{Basic Usage}
+
+The \verb|listing| environment allows to include source code of
+computer programs in \LaTeX\ documents by including the code between
+\verb|\begin{listing}| and \verb|\end{listing}|.
+
+\medskip
+
+\textbf{Example.}  In order to typeset the listing of a simple Python
+function (computing the cumulative sum of a list) you can use the
+following code in your \LaTeX\ document.
+\begin{xlist}
+  \begin{listing}
+    def cumsum(iterable):
+        return reduce(lambda res, x: res+[res[-1]+x], iterable, [0])[1:]
+  \end{listing}
+\end{xlist}
+\noindent
+These commands result in the following output:
+% \iffalse
+%</usage>
+%<*examples|usage>
+% \fi
+
+\begin{listing}
+  def cumsum(iterable):
+      return reduce(lambda res, x: res+[res[-1]+x], iterable, [0])[1:]
+\end{listing}
+% \iffalse
+%</examples|usage>
+%<*usage>
+% \fi
+
+\medbreak
+
+Differently from the \LaTeX\ \verb|verbatim| environment, the
+\verb|listing| environment can be indented to match the surrounding
+document source.  The following will work as expected:
+\begin{xlist}
+  \begin{figure}[h]
+    \begin{listing}
+      def cumsum(iterable):
+          return reduce(lambda res, x: res+[res[-1]+x], iterable, [0])[1:]
+    \end{listing}
+  \end{figure}
+\end{xlist}
+\noindent
+The Python code will be typeset using the same indentation as in the
+example above, despite the fact that they have different indentation
+in the \LaTeX\ source code.
+
+To make it easier to copy real program source code directly into your
+\LaTeX\ file, the code in listings can be indented by TAB characters
+instead of spaces.  The TAB spacing is assumed to be 8 character
+columns.
+
+In addition to the \LaTeX\ environment described above, there is also
+a command \verb|\filelisting| to typeset source code contained in a
+file.  The command takes one argument, the name of the file to
+include, and behaves very similar to the the \verb|verbatim|
+environment.
+
+\medskip
+
+\textbf{Example.}  In order to typeset the contents of a file
+\verb|cumsum.py|, we could use the following command.
+\begin{xlist}
+  \filelisting{cumsum.py}
+\end{xlist}
+
+\bigbreak
+
+There are various parameters to customise how listings are typeset.
+These parameters apply both to the \verb|verbatim| environment and to
+the \verb|\filelisting| command.
+\begin{itemize}
+\item The amount of space inserted before and after a listing is
+  given by \verb|\listingskipamount|.  The default value is
+  \verb|1ex|.  Commands like the following can be used to adjust the
+  amount of space.
+  \begin{xlist}
+    \setlength{\listingskipamount}{1\baselineskip}
+  \end{xlist}
+\item The indentation of the left margin of the typeset code is
+  determined by \verb|\listingindent|.  The default value is
+  \verb|2em|.  Commands like the following can be used to adjust
+  indentation.
+  \begin{xlist}
+    \setlength{\listingindent}{2cm}
+  \end{xlist}
+\item The font used in the listing is controlled by the macro
+  \verb|\listingfont|.  The default value is \verb|\normallistingfont|
+  which sets up a typewriter-like font.  Example: The following
+  command can be used to obtain more compact listings by slightly
+  reducing the fontsize and the line spacing.
+  \begin{xlist}
+    \renewcommand{\listingfont}%
+      {\normallistingfont\small\renewcommand{\baselinestretch}{0.95}}
+  \end{xlist}
+\item The penalty for page breaks inside a listing is given by
+  \verb|\listingpenalty|.  The higher this value, the less attractive
+  page breaks inside the listing are to \LaTeX's page breaking
+  algorithm.  The default value is 500.  The following command can be
+  used to completely disable page breaks inside listings.
+  \begin{xlist}
+    \listingpenalty=10000
+  \end{xlist}
+\item The penalty for page breaks just before or after a listing is
+  given by \verb|\prelistingpenalty| (default value 100) and
+  \verb|\postlistingpenalty| (default value -50), respectively.
+\end{itemize}
+
+\section{Extending the \textsf{listing} Environment}
+
+New \verb|listing|-like environments can be defined using the
+\verb|\NewListingEnvironment| macro.  This macro takes six arguments
+and uses them to define a new \LaTeX\ environment.  The arguments, in
+order, are
+\begin{enumerate}
+\item The name of the new environment.
+\item The number of extra arguments for the new environment
+  (normally~0).  These extra arguments of the environment, if any, are
+  substituted into the initialisation commands (\textit{i.e.}\ into
+  the fourth argument of \verb|\NewListingEnvironment|); see the
+  \verb|copylisting| environment, below, for an example.
+\item Commands to execute before the environment is entered
+  (\textit{e.g.}\ to add vertical whitespace).
+\item Initialisation commands, executed inside the environment
+  (\textit{e.g.}\ font/margin setup).
+\item The name of a macro (receiving one argument) which will be used
+  to typeset each line of input.
+\item Commands to execute after the environment is completed.
+\end{enumerate}
+
+\medskip
+
+\textbf{Example.}  The \verb|listing| environment provided by the
+\verb|jvlisting| package is defined using the following commands:
+%    \iffalse
+%</usage>
+%<*listingdef|usage>
+%    \fi
+
+%    \begin{macrocode}
+\let\listingfont=\normallistingfont
+\newcommand{\ListingTypesetLine}[1]{\noindent\hskip\listingindent\strut
+  #1\par\penalty\listingpenalty}
+\newcommand{\prelistingskip}{\endgraf\ifdim\lastskip<\listingskipamount
+  \removelastskip\penalty\prelistingpenalty\vskip\listingskipamount\fi}
+\newcommand{\postlistingskip}{\endgraf\penalty\postlistingpenalty
+  \vskip\listingskipamount}
+\NewListingEnvironment{listing}{0}{\prelistingskip}%
+  {\listingfont}{\ListingTypesetLine}{\postlistingskip}
+%    \end{macrocode}
+%    \iffalse
+%</listingdef|usage>
+%<*usage>
+%    \fi
+
+\medbreak
+
+\textbf{Example.}  An \verb|nlisting| environment which generates
+listings with additional line numbers can be defined as follows:
+%    \iffalse
+%</usage>
+%<*examples|usage>
+%    \fi
+
+%    \begin{macrocode}
+\newcounter{lineno}
+\newcommand{\typesetnline}[1]{\addtocounter{lineno}{1}%
+  \noindent\hskip\listingindent\llap{{\it\scriptsize\arabic{lineno}: }}%
+  \strut #1\par\penalty\listingpenalty}
+\NewListingEnvironment{nlisting}{0}{\prelistingskip}%
+  {\setcounter{lineno}{0}\listingfont}{\typesetnline}{\postlistingskip}
+%    \end{macrocode}
+%    \iffalse
+%</examples|usage>>
+%<*examples>
+\begin{nlisting}
+  for i in [1, 2, 3]:
+      for j in ['a', 'b', 'c']:
+          print str(i)+j
+\end{nlisting}
+%</examples>
+%<*usage>
+%    \fi
+
+\medbreak
+
+\textbf{Example.}  The following code defines a new
+\verb|copylisting| environment which does not only typeset the source
+code, but also saves a copy in an external file.
+%    \iffalse
+%</usage>
+%<*examples|usage>
+%    \fi
+
+%    \begin{macrocode}
+\newwrite\outfile
+\newcommand{\copytypeset}[1]{\immediate\write\outfile{#1}%

+\NewListingEnvironment{copylisting}{1}{\prelistingskip}%
+  {\immediate\openout\outfile=#1\listingfont}{\copytypeset}%
+  {\immediate\closeout\outfile\postlistingskip}
+%    \end{macrocode}
+%    \iffalse
+%</examples|usage>>
+%<*usage>
+%    \fi
+Here we used the second argument to \verb|\NewListingEnvironment| to
+indicate that the \verb|copylisting| environment should take an
+additional parameter (the output file name).  The new environment is
+used as follows:
+%    \iffalse
+%</usage>
+%<*examples|usage>
+%    \fi
+
+%    \begin{macrocode}
+\begin{copylisting}{listing1.c}
+  #include <stdio.h>
+
+  int
+  main()
+  {
+    puts("hello, world!");
+    return 0;
+  }
+\end{copylisting}
+%    \end{macrocode}
+%    \iffalse
+%</examples|usage>>
+%<*usage>
+%    \fi
+
+\section{Extending the \textsf{filelisting} Command}
+
+New \verb|filelisting|-like commands can be defined using the
+\verb|\NewFileListingCommand| macro.  This macro takes six arguments
+and uses them to define a new macro.  The arguments, in order, are
+\begin{enumerate}
+\item The name of the new command including the leading backslash.
+\item The number of arguments for the new command (normally~1).  These
+  arguments, including the first one which gives the file name, are
+  substituted into the third, fourth and sixth argument of
+  \verb|\NewFileListingCommand|); see the \verb|\prefixfilelisting|
+  command, below, for an example.
+\item Commands to execute before the listing is started
+  (\textit{e.g.}\ to add vertical whitespace).
+\item Initialisation commands, executed inside the scope of the
+  listing (\textit{e.g.}\ font/margin setup).
+\item The name of a macro (receiving one argument) which will be used
+  to typeset each line of input.
+\item Commands to execute after the listing is completed.
+\end{enumerate}
+The first argument of the newly defined macro always denotes the name
+of the file to include.
+
+\medskip
+
+\textbf{Example.}  Using the auxiliary functions for the
+\verb|listing| environment, the built-in \verb|filelisting| command
+can be defined as follows:
+%    \iffalse
+%</usage>
+%<*listingdef|usage>
+%    \fi
+
+%    \begin{macrocode}
+\NewFileListingCommand{\filelisting}{1}{\prelistingskip}%
+  {\listingfont}{\ListingTypesetLine}{\postlistingskip}
+%    \end{macrocode}
+%    \iffalse
+%</listingdef|usage>
+%<*usage>
+%    \fi
+
+\medbreak
+
+\textbf{Example.}  The following command defines a macro to read a
+file and to prefix every line of the resulting listing with a given
+string.

+% \section{Implementation}
+%
+% This section describes the internal implementation of the
+% \verb|jvlisting| package.  In order to avoid name clashes with other
+% packages, the names of all internal macros defined in this package
+% start with the prefix \verb|jvl@|.  The following is the preamble
+% for the package file.
+%    \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{jvlisting}[2011/06/27 v0.1 Formatted Program Listings]
+%    \end{macrocode}
+
+% \subsection{Processing the Lines of Input}
+%
+% We start by provinding a macro \verb|\jvl@iterlines| which can be
+% used to iterate over all lines of input until a line containing some
+% marker is found.  The marker is given as the argument \verb|#1| to
+% the \verb|\jvl@iterlines| macro.  Each line is processed by
+% appending the token \verb|\jvl@eol| (used later to recognise the end
+% of line) and by prepending \verb|\jvl@dropempty| (for the first and
+% last line) or \verb|\jvl@countspaces| (for all other lines).
+%    \begin{macrocode}
+\def\jvl@iterlines#1{\obeylines
+  \expandafter\jvl@iterla\expandafter{#1}{\jvl@dropempty}}
+{\obeylines
+\gdef\jvl@iterla#1#2#3
+  {\def\jvl@testmarker##1#1{}%
+  \expandafter\def\expandafter\w\expandafter{\jvl@testmarker#3#1}%
+  \ifx\w\empty%
+    \def\next{#2#3\jvl@eol\jvl@iterla{#1}{\jvl@countspaces}}%
+  \else%
+    \def\y##1#1##2#1{\jvl@dropempty ##1\jvl@eol\jvl@end##2}%
+    \def\next{\y#3#1}%
+  \fi\next}}
+%    \end{macrocode}
+
+% The next step in processing is to drop the first line (whatever
+% comes directly after the opening \verb|begin| statement) and the
+% last line (whatever comes directly after the closing \verb|end|
+% statement), if they consist only of white space.
+%    \begin{macrocode}
+\def\jvl@dropempty{\jvl@dropa{}}
+\def\jvl@dropa#1#2{\ifx\jvl@eol#2%
+    \let\next=\relax
+  \else
+    \if#2 \def\next{\jvl@dropa{#1#2}}\else
+      \def\next{\jvl@countspaces #1#2}\fi
+  \fi\next}
+%    \end{macrocode}
+
+% Next we determine the indentation level of the current line by
+% expanding TAB characters and then counting spaces.  The result is
+% stored in the scratch counter \verb|@tempcnta|.
+%    \begin{macrocode}
+\def\jvl@countspaces{\@tempcnta=0\jvl@counta}
+{\catcode`\^^I=12
+\gdef\jvl@counta#1{\expandafter\if\noexpand#1^^I%
+    \advance\@tempcnta by8\divide\@tempcnta by8\multiply\@tempcnta by8
+    \let\next=\jvl@counta
+  \else
+    \expandafter\if\noexpand#1 %
+      \advance\@tempcnta by1
+      \let\next=\jvl@counta
+    \else
+      \def\next{\jvl@fixspaces #1}
+    \fi
+  \fi\next}}
+%    \end{macrocode}
+
+% Using the value in \verb|@tempcnta|, we fix the indentation by first
+% subtracting the common indentation level (stored in \verb|\jvl@idt|)
+% and then inserting the required number of spaces (using
+% \verb|\space|).
+%    \begin{macrocode}
+\newcount\jvl@idt \jvl@idt=-1
+\def\jvl@fixspaces#1{\ifx\jvl@eol#1\else
+  \ifnum\jvl@idt<0
+    \jvl@idt=\@tempcnta
+  \else
+    \ifnum\@tempcnta<\jvl@idt\jvl@idt=\@tempcnta\fi
+  \fi\fi\jvl@fixa#1}
+\def\jvl@fixa{\ifnum\@tempcnta>\jvl@idt
+    \advance\@tempcnta by\m@ne
+    \def\next{\jvl@fixa\space}%
+  \else
+    \let\next\jvl@output
+  \fi\next}
+%    \end{macrocode}
+
+% Finally, by matching the \verb|jvl@eol| inserted by the
+% \verb|\jvl@iterlines| function above, we can apply the output
+% function \verb|\jvl@typeset| to the processed line.
+%    \begin{macrocode}
+\def\jvl@output#1\jvl@eol{\jvl@typeset{#1}}
+%    \end{macrocode}
+% The symbol \verb|\jvl@typeset| will be defined inside the
+% \verb|\begin{listing}| command; since neested listings are not
+% possible, using a global name for the output function is no
+% problem.
+
+% \subsection{Defining Listing Environments}
+%
+% Given the code above, we can now define the
+% \verb|\NewListingEnvironment| macro.  Some care is needed when
+% constructing the marker for use in the \verb|\jvl@iterlines| method,
+% because the text we need to match uses category code 12 (``other'')
+% for all characters.
+%    \begin{macrocode}
+\begingroup
+  \catcode`|=0 \catcode`[=1 \catcode`]=2
+  \catcode`\{=12 \catcode`\}=12 \catcode`\\=12
+  |gdef|jvl@makemarker#1[%
+    |expandafter|gdef|csname jvl@@#1marker|endcsname[\end{#1}]]
+|endgroup
+\def\jvl@setup{\begingroup
+  \parskip0pt \advance\leftskip by\@totalleftmargin
+  \let\do\@makeother\dospecials \catcode`\^^I=12}
+\def\NewListingEnvironment#1#2#3#4#5#6{\jvl@makemarker{#1}%
+  \expandafter\newcommand\csname #1\endcsname[#2]{#3\jvl@setup
+    #4\def\jvl@end{\end{#1}}\let\jvl@typeset=#5%
+    \expandafter\jvl@iterlines\csname jvl@@#1marker\endcsname}%
+  \expandafter\gdef\csname end#1\endcsname{\endgroup #6}}
+%    \end{macrocode}
+
+% \subsection{Reading Listings from File}
+%
+% When reading listings from a file, we get the lines terminated by
+% \verb|^^M| characters.  The following function is a replacement for
+% \verb|\jvl@iterlines|, used to read lines from a file and to strip
+% of the trailing \verb|^^M| characters:
+%    \begin{macrocode}
+\newread\jvl@fileinput
+\def\jvl@iterfile{\read\jvl@fileinput to\l
+  \ifeof\jvl@fileinput
+    \let\next\relax
+  \else
+    \expandafter\jvl@iterfa\l
+    \let\next\jvl@iterfile
+  \fi\next}
+{\catcode`\^^M=12
+\gdef\jvl@iterfa#1^^M{\jvl@countspaces#1\jvl@eol}}
+%    \end{macrocode}
+%
+% In analogy to \verb|\NewListingEnvironment|, the following macro is
+% used to define new functions for listing file contents.
+%    \begin{macrocode}
+\def\NewFileListingCommand#1#2#3#4#5#6{%
+  \ifnum#2<1
+    \PackageError{jvlisting}{%
+      Invalid number of arguments: `#2'
+    }{%
+      The second argument to \protect\NewFileListingCommand\space must be at
+      least 1.
+    }%
+  \fi
+  \newcommand{#1}[#2]{#3\jvl@setup\catcode`\^^M=12
+    #4\let\jvl@typeset=#5%
+    \openin\jvl@fileinput=##1\jvl@iterfile\closein\jvl@fileinput
+    \endgroup #6
+  }
+}
