Hi!
If you remember, I have set up a small very local wiki using the wikipedia scripts. Thanks for the comments I received last time. They were very valuable.
I have not solved my problem with page editing; I intended to reload all the scripts. I got an account on sourceforge, but did not (yet) manage the download. I have a password pb. Is it needed to be registered in the project itself to download?
One of the reasons why I looked to wikipedia was because of maths and the use of TeX.
However, when I looked to the details, I found (to my taste) too many limitations with the followed approach. Then I wrote an extension to outputpage.php to replace the call to texvc by calls to pdflatex then imagemagick convert. This has reached the stage of minimal functionality (translation and caching). This allows me to have full maths, without having to remember what is supported or not, or modified, compared to LaTeX. In addition, we intend to use it for small music scores (using Mu sixTeX or possibly PMX), and I have in mind some other uses of LaTeX.
Please understand that I'm not trying to (re)open a debate. I've read the "math markup" page on meta.wikipedia (and music markup as well), and I'm aware of (some of) the drawbacks of the approach I followed. I mentionned what I did just in conformance with GPL: if there is any interest in this small piece of code (which I doubt, it's rather trivial!), just say it.
