% \section{Introduction}
%
% texments is a package that is used to connect the not-yet award winning
% source code colorizer library Pygments (\url{http://pygments.org/})
% with \LaTeX documents. That means that it is neccessary to have
% Pygments installed and that the \texttt{pygmentize} command is 
% available.
%
% \section{Usage}
%
% This package does not provide many fancy features, it is just meant
% as an easy bridge between the highlighter and LaTeX. It calls
% internally the \texttt{pygmentize} command, so you need to start it
% with \texttt{-shell-escape} activated. Note that this might change
% in the future.
%
% \DescribeMacro{\usestyle\marg{stylename}}
% This macro needs to be called at least once to set the style that
% pygments should use to highlight all code.
%
% One quite useful style is the ``bw'' style which is, as the name
% somehow implies black and white.
%
% \usestyle{default}
%
% \DescribeMacro{\pygment\marg{language}\marg{code}}
% To highlight a chunk of code, you can use the \texttt{pygment}
% macro.
%
% An example for this is the following Python code:
%
% \pygment{python}{print "Hello World"}
%
% \StopEventually{}
%
% \section{Implementation}
%
% \begin{macro}{\usestyle}
% This macro calls \texttt{pygmentize} with the appropriate style
% name and gets the color definitions that will be used in all
% following code listings.
%    \begin{macrocode}
\newcommand{\usestyle}[1]{
  \immediate\write18{pygmentize -S #1 -f latex > \jobname.pyg}
  \input{\jobname.pyg}
}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{\pygment}
% This macro takes the code in the second argument and feeds it
% to \texttt{pygmentize}, so that it outputs code highlighted
% to the rules of the first argument.
%    \begin{macrocode}

\newwrite\code
\newcommand{\pygment}[2]{
  \immediate\openout\code\jobname.pyg
  \immediate\write\code{#2}
  \immediate\closeout\code

  \immediate\write18{pygmentize -l #1 -f latex -o \jobname.out.pyg \jobname.pyg}
  \input{\jobname.out.pyg}
}
%    \end{macrocode}
% \end{macro}
%
% \Finale
