Hi, first, let me apologize, if this is not the correct mailinglist to ask. Is there some mailinglist for the Sphinx project? http://sphinx.pocoo.org/ I tried to go to the #python-docs channel, but it doesn't exist. Anyway, the project is great. We moved the docs in ipython to it and we are going to move sympy docs as well. We found a bug though. If python-pygments isn't installed, sphinx doesn't say anything, "make latex" hapilly generate a latex file, but this latex file fails to compile: ! Undefined control sequence. <argument> In \lb []1\rb []: from ipython1.kernel import client l.1205 ...rb[]: from ipython1.kernel import client That's because the latex file is missing some definitions, like \lb, that only get included when python-pygments is installed. Do you think the file sphinx/highlighting.py line 30 could be fixed to emit a large warning message, that the latex output will be broken (possibly with an explanation of the problem)? That way one can easily spot it and fix it. Actually it took my 45 minutes of debugging with winpdb to figure out what's wrong, because I had one computer where it worked and another where it didn't. I compared all Debian latex packages on both, but it didn't occur to me the problem could by in missing pygments. But I am glad I figured this out. :) Thanks a lot, Ondrej
