Syntax highlighting of code blocks in beamer slides

Syntax highlighting of code blocks in beamer slides

Hello,

we want to create slides via beamer. This works fine except for source code listings (#begin_src python...#end_src) - if exported as HTML they have syntax-highlighting as expected, however, when exported as LaTeX the syntax-highlighting is lost. Is there a way to create beamer slides with source code snippets that have syntax-highlighting?

Many thanks in advance!

Warm regards, 
 Stefan

I'm following this tutorial for this:
http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-12-3

Yup, I followed the tutorial and set up minted some time ago and I have
not looked back: I just tried the following

--8<---------------cut here---------------start------------->8---
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_FRAME_LEVEL: 1
#+BEAMER_HEADER_EXTRA: \usetheme{default}\usecolortheme{default}
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_envargs(Env Args) %4BEAMER_col(Col) %8BEAMER_extra(Extra)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 :ETC


* foo

#+BEGIN_SRC python :exports code
  for x in range(100):
      print "x=%d , x^2=%d" % (x, x*x)
#+END_SRC
--8<---------------cut here---------------end--------------->8---


and I get a caleidoscope of colors.

The TeX FAQ has some details about where to get minted and its dependencies
(it requires an external Python script, called Pygments):

Dear Alan,
dear Nick,

many thanks for your help. Installing minted and pygments and then putting the emacs-lisp snippet from

http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-12-3

into my .emacs file did work. Now my code snippets are syntax-highlighted! Do you have any suggestions on which pygments color styles work well in presentations?

Many thanks in advance,
 Stefan
