@ -29,5 +29,26 @@ Conversely, how about adding a plugin to support exporting to LaTeX?
a latex plugin. Examples [here](http://ng.l4x.org/latex/). Currently without image support for hevea. And the latex2html
output has the wrong charset and no command line switch to change that. Dreamland.

Okay, now is the time for a mid term report i think.
The LaTeX Plugin for ikiwiki is now usable, except for the security check. This means at the moment the latex code is not validated, but only added into a very basic latex template. and the image is generated via this path: latex -> dvips -> convert (.tex -> .dvi -> .ps -> .png).
The resulting .png is moved into the imagefolder. The name of this image is the md5hash of the code the user wrote into the wiki. So on a second run there is no need to recreate this image, if it exists. This will fasten up all but the first generation of the page.
The generation of the image is done in an temporary folder in /tmp created with tempdir from File::Temp. The tmp-folder name is something like: $md5sumdigest.XXXXXXXX. if there is an .tex file already in this dir it will be overwritten.
So until now i finished the basic things, now the most important task is to make an good input validation.
This is a bit eased since it is not possible to execute shell commands in perl. Furthermore adding additional packages won't work since the code comes from the user is inserted after \begin{document}. Therefore this will result in an error (and this will stop latex from working --> no image is created).
So my task for the next weeks is to write an good input validation.
I think this progress is okay, since I'll had to learn the last 5-6 weeks for my final exams in university therefore I can't do anything. From now on I have 3 months of freetime and I'll use them to work heavily on this plugin.
So I think I'm inside my own timetable. :)
ps: Since I found nothere the possibility to upload an file, here is an link to my page where you can have a look. Comments are very welcome ;-)
