I’m currently preparing a small presentation about Python and functional programming and need to put syntax highlighted source code on my latex beamer foils. Here is a small summary how I did it:
Step1
Prepare a file code.py containing some Python code (or code from any other language):
print "Hello World!"
Step2
Install Pygments via easy_install Pygments
Step3
Create TeX code for the code file with
pygmentize -O full -f latex code.py > code.tex
This produce a complete LaTeX document code.tex with some usepackage directives and command definitions for different colours as well as a verbatim block which can be integrated in a LaTeX Beamer frame.
Step4
Put the newcommand and usepackage stuff in your beamer tex file and create a new frame to include the code snippet:
\begin{frame}[fragile]
\begin{Verbatim}[commandchars=@\[\]]
@PYay[print] @PYaB["]@PYaB[Hello World!]@PYaB["]
\end{Verbatim}
\end{frame}
Step5
You need to run pygmentize only once with the -O full parameter. For every additional code snippet this parameter can be omitted to produce the latex verbatim block only.
