Corrections and enhancements.

[ofv@…]

Attached is an enhanced version of this interesting plugin. It contains the following stuff:

• Corrected a bug where dvipng was invoked with imgname instead of imgpath.

• Added support for configuring parameteres on trac.ini. This parameterers are supported: cache_dir, latex_cmd and dvipng_cmd. Example configuration for my windows machine with MikTex:

[tracmath]
cache_dir = c:/TEMP
latex_cmd = c:/apps/miktex/miktex/bin/latex.exe
dvipng_cmd = c:/apps/miktex/miktex/bin/dvipng.exe

• Images are centered vertically.

• Support for writing latex math in the usual way, i.e.: {{{$\pi \over 2 $}}} (Please observe the space before the closing $.) This feature is a bit controversial. It remains to be seen the implications of using the dollar sign for as a delimiter. This feature can be easily removed by deleting the IWikiSyntaxProvider methods.

TODO

• Sanity checking for trac.ini parameters.

• trac.ini entries for parameters for dvipng and latex.

• Some system for deleting old entries on the cache.

• Support for international characters withing Latex text. Right now, writing something like [[latex($á$)]] produces a traceback.
