I'd like to have Trac colorize my aspx files but I can't find a way to make it work. I can easily add a mime-type/extension mapping for most Pygments lexers, but the CSharpAspxLexer doesn't have an assigned mime type (see http://pygments.org/docs/lexers/#lexers-for-net-languages). I've tried a couple things but I don't see a way to connect the [mimeviewers] section to Pygments without a mime type. The CSharpLexer works automatically and looks great, but only for .cs files (as it should).
I'm using Mercurial as a repository so I can't set the mime type manually; that's not a good solution anyways. My Trac installation is in Windows. Any thoughts?
