The Math extension provides support for rendering mathematical formulae. An overview of what can currently be done with this extension is found at the English Wikipedia's documentation.

  • 下载文件,并将其放置在您extensions/文件夹中的Math目录内。
  • 将下列代码放置在您的"LocalSettings.php "的底部:
    require_once "$IP/extensions/Math/Math.php";
    // See below for installation requirements and configuration settings:
  • 运行更新脚本,它将自动创建此扩展必须依赖的数据库表。
  • To see math beyond a plain text output, follow instructions below for enabling various math output modes.
  • Yes 完成 – 在您的wiki上导航至Special:Version,以验证已成功安装扩展。

Vagrant installation:

  • 如果使用Vagrant ,请通过vagrant roles enable math --provision安装


Beginning from MW 1.23+ you can use a Mathoid server that uses MathJax to convert texvc input on the server side to MathML+SVG rendering. Mathoid is the rendering mode that is going to be used on future Wikipedia. For that the following settings are recommended:

// Set Mathoid as default rendering option;
$wgDefaultUserOptions['math'] = 'mathml';

Check out Mathoid to find instructions how to run your own Mathoid server.

List of all configuration settings

Setting name Default value Description
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.
$wgMathMathMLTimeout 20 The timeout for the HTTP-Request sent to the MathML to render an equation, in seconds.
$wgMathDisableTexFilter false Option to disable the tex filter. If set to true any LaTeX expression is parsed this can be a potential security risk. If set to false only a subset of the TeX commands is allowed. See the wikipedia page Help:Math for details.
$wgMathMathMLUrl http://mathoid.testme.wmflabs.org Defines the link to the mathoid server.

Purging pages that contain equations

Specifying the URL-parameter action=purge does not force the math equation to re-render the math tags. If a complete re-rendering of the math tags is desired the URL-parameter action=purge&mathpurge=true has to be passed. Be aware that this might cause side effects with other pages since the math extension uses the hash of the input TeX-input-string as the caching key. e.g. if you would force the re-rending with mathpurge option for a page containing the equation $E=mc^2$, the new rendering result would be used on all other pages containing $E=mc^2$ after the individual page caches are invalidated.

Error reporting

If something is wrong with the math extension you can report that at Phabricator. In addition you should check how your problem relates to the automated unit tests that are generated from the page CoverageTest.

Further reading

The Math extension can do much more, beside the basics described here. Check out Extension:Math/advancedSettings for old versions and further information.
