How can I add a code listing to a beamer note slide?

I tried the following which doesn't work:

\note{{\tiny{This is a note
foo bar

Any suggestions?

I've never worked with beamer \note. Could you please add a minimal example for your problem which compiles? –  Matten Dec 14 '10 at 8:03

Welcome! One problem with the snippet you provide is an unmatched brace. But even so, like verbatim, lstlisting does strange things with category codes of characters which usually precludes it from being in the argument of another macro.

Inspired by this post to the beamer mailing list, I found a workaround with the \lstinputlisting command. You have to put your code snippet in a file, but using the linerange options you can excerpt multiple snippets from the same file.

\setbeameroption{show notes}

I highly recommend the "minted" package for all code listings. Note that if you use this on a beamer slide, it must be fragile:

\begin{frame}[fragile]{Python rocks}
def foo(self, bar):
   return bar

Note: The minted package needs Pygments for syntax highlighting.

Oh, that sounds interesting. I tried it OMM and I got a message that says that 'pygmentize' has to be installed. What is that and how would one install it? –  Matthew Leingang Dec 14 '10 at 19:44
@Matt: Welcome to tex.sx! A tip: If you indent lines by 4 spaces, then they're marked as a code sample. You can also highlight the code and click the 'code' button (101010). –  Hendrik Vogt Dec 15 '10 at 10:37
@Matt: Does ``minted'' solve this issue? Or is it just a general recommendation. I can't switch directly, though, I already have created a bunch of specialized listing style files. –  Normen Müller Dec 15 '10 at 14:15
@Matt pygmentize is a program for code highlighting and typesetting. Its also used by Python documentation. minted is the wrapper for LaTeX. You will also need -shell-escape on your command line. –  Matt Knepley Dec 16 '10 at 18:07
@Normen It should do what you want. Did you have problems? –  Matt Knepley Dec 16 '10 at 18:07

Using \lstinputlisting as suggested by Matthew is one possibility. However, if you (like me) prefer to not have dozens of small listing files separated from the LaTeX sources, you could also render the listing into a lrbox box and \usebox this inside the \note:


% Verbatim material in commands (\note{}) not possible --> box it
int fak( int n ) {
 for( int i = n-1; i > 1; --i )
   n *= i;
 return n;

  \note{ Iterative solution:\par\usebox{\LstA}}
