Pygments & syntax highlighting

[Emmanuel Blot]

Hi,

I'm not sure how to add file type that Pygments supports natively, but
that Trac does not recognize.

For example, CMake files have been supported by Pygments for a long
time (since 1.2), but Trac does not manage them.

It seems the way to go (from
http://trac.edgewall.org/wiki/TracIni#mimeviewer-section) is to add
CMake type to the mime_map option.

I've added "text/x-cmake:cmake" and now the syntax highlighter works
with "#!cmake" in quoted blocks. However, Trac file browser does not
highlight CMakeLists.txt files. I've added
"text/x-cmake:CMakeLists.txt" to the mime_map option, but it does not
help.

1. Specific question: How to specify to Trac that "CMakeLists.txt"
files should be highlighted
2. Generic question: How to tell Trac to defer all highlighting
decisions to Pygments, which already knows about all supported types,
rather than letting Trac performs the mapping on its own - is it even
possible?

TIA,
Manu

I believe we only look for the suffix, not for the full name with
fnmatch. See get_mimetype() in trac/mimeview/api.py.

No. This is #5533.

So basically the only "solution" you have for now short of implementing
#5533, is to do a `svn pset svn:mime-type text/x-cmake` on your CMake
files in the repository.

Ok ;-)

Ok. I don't think it worth dealing with so many changes. I can leave without.

Thanks for your help,
