Extension:Blahtex

Blahtex is a TeX-to-MathML converter intended for use with MediaWiki. It also outputs PNG graphics, much as the current TeX implementation on Wikipedia does.

It is under active development as of July 2006; the current version is 0.4.4 (released 25/Mar/2006).

The principal author of blahtex is known in Wikipedia circles as Dmharvey.

BlahtexWiki


Jitse Niesen has been working on a test wiki to demonstrate how blahtex can be integrated into MediaWiki. The aim is for MediaWiki to be able to output MathML in addition to the HTML and PNG graphical output that it can presently do (via texvc). See also /Embedding Blahtex in MediaWiki.

Features

 * Supports all symbols in TeX, LaTeX and AMS-LaTeX
 * Supports non-ASCII characters (in PNGs, "extended latin", cyrillic and japanese are all ok)
 * Detailed syntax error reporting (not just "syntax error")
 * Knows TeX's spacing rules and generates MathML spacing markup accordingly

Future plans
Blahtex is currently undergoing a port to Python. This will take some time. The parser is being redesigned to provide better TeX compatibility than version 0.4.4.

Compatibility: lists browsers which have been tested with blahtex and BlahtexWiki. Please add successful configurations and failures here. Note that this information may become out of date due to continuing work on both blahtex and BlahtexWiki.

Syntax: known differences between blahtex and texvc syntax.
