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. See the README in the texvccheck subdirectory for more info on setting up the security checking tools for MathJax and LaTeXML. 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 $wgMathUseLaTeXML = true; It is possible to choose LaTeXML as default option (for anonymous user) by setting $wgDefaultUserOptions['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 }; } Attributes of the element: attribute "display": possible values: "inline", "block" or "inline-displaystyle" (default) "display" reproduces the old texvc behavior: The equation is rendered with large height operands (texvc used $$ $tex $$ to render) but the equation printed to the current line of the output and not centered in a new line. In Wikipedia users use :$tex to move the math element closer to the center. "inline" renders the equation in with small height operands by adding {\textstyle $tex } to the users input ($tex). The equation is displayed in the current text line. "inline-displaystyle" renders the equation in with large height operands centered in a new line by adding {\displaystyle $tex } to the user input ($tex). For testing your installation run php tests/phpunit/phpunit.php extensions/Math/tests/ from your MediWiki home path. == Logging == The math extension supports PSR-3 logging: Configuration can be dona via $wgDebugLogGroups['Math'] = array( 'level' => 'info', 'destination' => '/path/to/file.log' );
