howto: syntax highlighted source code in latex beamer

[ssam]

I wanted to put some python source code in to a presentation i am doing, using Latex beamer. It took me a while to figure out, so i am posting it here.

I used http://pygments.org/, which claims to take almost any language input, and has many output formatters. it can do python code into latex.

There is a bug in the ubuntu version. Some of the colour commands it defines for latex clash with common latex packages. it is fixed in 0.10, so a grabbed the debian package from
http://packages.debian.org/sid/all/p...ments/download (double click to install).

Now from the command line run

pygmentize -f latex hello.py

(replacing hello.py with the source code you want to put in you latex document).

This outputs (something like)(the forums may mangle this)

\begin{Verbatim}[commandchars=@\[\]]
@PYaD[#!/usr/bin/env python]
@PYay[print] @PYad["]@PYad[hello]@PYad["]
\end{Verbatim}

Those 'PYaD' type things are commands for colours, but latex needs to be told what they mean. if you run

pygmentize  -O full -f latex hello.py

you get the full output for a complete document.

The use package, and newcommand lines need to be put in your latex document, between the \documentclass and \begin{document} lines. The UTF-8 bit seems not to be neccessary.

or you can create file called pygments.tex, containing

\usepackage{fancyvrb}
\usepackage{color}

and then just put

\include{pygments}

in your latex document.

And one more thing. If you are using beamer, then putting a \Verbatim section in a frame can cause trouble. so you need to make a fagile frame with:

\begin{frame}[fragile]

Thanks!

Hey, thanks a lot. This was a really nifty post about how to use pygmentize. I'm using it now rather contently. Cheers.

[jackliddlephysics]

Thanks ssam, works perfectly. You've saved me a lot of time

[carlohamalainen]

Thanks ssam, that works perfectly.

[SEBASTIANFFX]

Thanks, it take me a lot of time to get the <fragile> thing.
It works great!

[rulo4]

I use

pygmentize -f latex file.py

I get

\begin{Verbatim}[commandchars=\\\{\}]
\PY{c}{#!/usr/bin/env python}

\PY{k}{print} \PY{l+s}{"}\PY{l+s}{Hello World!}\PY{l+s}{"}
\end{Verbatim}

instead of that you say.

¿How can I fix that?
