Hi
I thought it might be nice to be able to insert formulas in the wiki
pages, so I've hacked together something here:
http://www.lyx.org/~chr/wiki/pmwiki.php?pagename=Math.Math
which does something similar to what latex-preview, i.e. this markup
[[$ x = y + z $]]
causes a .tex-file to be created that will contain
$ x = y + z $
and latex then compiles this to produce a .dvi-file that dvipng finally
converts into a .png-file. (The formulas and images are cached for
performance reasons).
Now to my question. I'm guessing that letting arbitrary latex code be
executed using this mechanism is a *huge* security problem.
(Well, assuming that the hacker also knows his latex).
Can I filter the latex-code somehow to make it safe enough, i.e. so safe
that we feel it can be left running on wiki.lyx.org?
