Tomasz, could you please also implement a <tex>...</tex> which goes straight to TeX, so that matrices, commutative diagrams, chess diagrams, chemical structure formulas, music notes and flow charts can be typeset conveniently? Or would you prefer that I do it?

Regardless of the "should we allow full LaTeX" debate, I tend to think that some means of typesetting music could greatly benefit Wikipedia. Music theory is certainly a huge topic, and one that Wikipedia ought to be able to document and cover properly.

One part of music theory is math, and for the math we now have Tomasz's texvc module. But most of music theory requires being able to typeset notes, chords, music, etc.

Music typesetting could be provided by GNU LilyPond, http://lilypond.org/. (It's part of the GNU project, folks, so Wikipedia should support GNU LilyPond, if for no other reason than to promote wider use and adoption of Free and Open standards and software.)

LilyPond is a plaintext syntax, very TeX-like. It ought to be pretty trivial to create a texvc-like module for Wikipedia that renders LilyPond notation into PNGs. The LilyPond syntax could be put within <music> ... </music> tags, or something similar.

Anyways, it's certainly something to look into!

Peace out,

Derek
