Has somebody
written a script to convert mediawiki markup to html? I'd
need something which works with embedded latex. Looking at the
mediawiki source it doesn't seem like it should be *that* hard but I
haven't tried yet.
Yes, we've written one; it's called "MediaWiki". It's written in
PHP,
and uses a helper program 'texvc' to handle LaTeX fragments and pass
them to the renderer.
The intent was to have something which didn't depend on a database,
but could take wiki markup on say standard input...
If you can't or don't want to try to use
MediaWiki's parser, there are a
huge number of more or less somewhat-implemented clone parsers in
various languages:
