Has anyone gotten Trac working with Markdown?  What exactly does it take?

A while back I did an ugly hack that mostly worked (but I haven't used
it in a while).  I just uses a giant regular expresion to extract link
targets, run them through the wiki engine, and then process the whole
thing with markdown.py.

There must be a better way.

"""Trac plugin for Markdown Syntax (with links)

Everything markdown-ed as a link target is run through Trac's wiki
formatter to get a substitute url.

Tested with Trac 0.8.1 and python-markdown 1.4 on Debian GNU/Linux.

It doesn't seem that ugly, once I managed to parse it. :)

A question though: this being a "plugin" means that all Markdown formatting
would need to be surrounded by {{{...}}}, right?  Is there a way of avoiding
this?

Judging by http://trac.edgewall.org/ticket/615, I am guessing that there
isn't any blessed solution.  But one would think that there should be a way
to hack it to default to Markdown?

That's right, it needs the curly braces.  I'm actually not using Trac
right now, and I was never very familiar with the internals.

One thing I remember is that the Trac devs seemed scornful of people
wanting to get rid of the curly braces.

A lot of users wanted that feature, so the devs may have changed their
mind since then, but I doubt it.

Sure, it does seem that they are not interested in supporting it.  But if
trac is designed well, it shouldn't be that hard to make this chance without
their support.

However, I spent way too much time today trying to install trac on dreamhost
and am ready to give up on it.  I then tried MoinMoin and remembered why I
stopped using it earlier.  I was going to try Infogami next, but the fact
that I would need to install Mercurial on dreamhost makes me suspect that
there would be a lot more of wasted time ahead.  Unless someone can suggest
some other option that I haven't considered yet, I think I'll just go and
fix the current wiki by installing a new version.
