This version (for MediaWiki 1.19) has some changes since previous versions: * rendering options have been reduced to just 'Always PNG' and 'Leave it as TeX' ** all other rendering options will merge to PNG. * initial experimental support for integrating MathJax client-side rendering See the README in the math subdirectory for more info on setting up the low-level conversion tools. MathML support: If you prefer MathML rather than images you can use LaTeXML to convert the math tags to MathML. To use that feature you have to enable LaTeXML by setting $wgUseLaTeXML = true; It is possible to choose LaTeXML as default option (for anonymous user) by setting $wgDefaultUserOptions['math'] = MW_MATH_LATEXML; in the LocalSettings.php file. The LaTeXML option requires php5-curl to be installed. Without php5-curl no proper error handling can be guaranteed. Furthermore, a core version of wmf/1.22wmf7 or newer is recommended. Otherwise, errors in LaTeXML can lead to mal-formatted XML output and disturb the page layout. MathJax configuration: Client-side configuration of MathJax can be done by specifying a mathJax.config table, which takes a table as described in: http://docs.mathjax.org/en/v1.1-latest/options/index.html#configuration Example: if ( typeof mathJax === 'undefined' ) { mathJax = {}; mathJax.config = { showProcessingMessages: true }; } For testing your installation run php tests/phpunit/phpunit.php extensions/Math/tests/ from your MediWiki home path.
