Introduction[edit | edit source]

The Math extension (or, more broadly, the rendering of the <math> tag) has a long history. It has been modified by a number of different people with different goals, different ideas, and different and programming styles, using different underlying technologies. As a result, the extension's current implementation is more a grown than a well-designed or -documented structure.

An overview of what can currently be done with this extension is found at the English Wikipedia's documentation.

The aim of this page is to co-ordinate the development activities concerning this extension.

Wanted features[edit | edit source]

  • MathML support
  • Specification of the subset of commands that are allowed "MediaWiki uses a subset of AMS-LaTeX markup, a superset of LaTeX markup which is in turn a superset of TeX markup, for mathematical formulae"
  • Automatic testing
  • Security stategie
  • Links to formula (in the current development version $parser->nextLinkID() is used to generate an anchor id, which is not human readable. The problem is that the same TeX string can occur more than once in page.) see Extension:MathSearch
  • Automatic numbering of equations (bug 5600)

Current activities[edit | edit source]

Currently the following changesets are open: https://gerrit.wikimedia.org/r/#/q/status:open+project:mediawiki/extensions/Math,n,z

Future steps[edit | edit source]

Integrate LaTeXML to enable MathML. The current status of this implementation can be followed at here.

As a first demo, rendering all Wikipedia pages that contain math can be tested at [1].

Currently there are only 8 of 284303 equation that can not be rendered. As soon as this problem is solved a testrun within the wikimedia foundation is desired.

Bugs and Roadmap and random thoughts (From the discussion page)[edit | edit source]

Feature Requests[edit | edit source]

  • 3840 Looks for high math images printing. The only thoughts I have here are to switch form dvipng to dvisvg and use svg images which would look better at all scales and hopefully would print better. Related bugzilla:15777
  • 5856, 10186 and 6722 are related to mhchem package. Users seem to be very interested in this. Perhaps this should looked into.
    • 20902 request to install chemarr
  • 12223 Desperately needed and long overdue inline math tags. Probably would only make sense if base line issue is sorted out. Should we use a slightly smaller font for inline math? Not done in latex but may look nice on the web.
  • 28258 It would be nice to have some commutative diagram packages. xy-pic may be a good option.
  • 31546 Make error messages for Math use wikitext (Nobody assigned... Maybe target release 2.1)
  • 36063 Math settings provided by MathJax should be a part of user preferences. (Nobody assigned... Maybe target release 2.2)

Visual Appearance Issues[edit | edit source]

  • 15777 I have to agree this looks fairly bad. Curious if switching to dvisvg would straighten this out.
  • 38722

For a list of all bugs see [2]

Localization[edit | edit source]

  • 2458 In TeX/LaTeX terms, this is about the babel package.
