Not until now, but I've now added a "source-read" event to Sphinx SVN
to be able to preprocess source text. Use it like this (e.g. in your conf.py):
r = re.compile(r'\$([^$]+)\$')
def substitute_math(app, docname, text):
text[0] = r.sub(r'::math:`\1`', text[0])
def setup(app):
app.connect('source-read', substitute_math)
Be aware, however, that this will replace really _all_ occurrences of
$abc$ anywhere in the source text.
cheers,
Georg
