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.
InstallationEdit
- Download and place the file(s) in a directory called
Math
in yourextensions/
folder. - Add the following code at the bottom of your
LocalSettings.php
:require_once "$IP/extensions/Math/Math.php"; // See below for installation requirements and configuration settings:
- Run the update script which will automatically create the necessary database tables that this extension needs.
- To see math beyond a plain text output, follow instructions below for enabling various math output modes.
- Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
Vagrant installation:
- If using Vagrant , install with
vagrant roles enable math --provision
ConfigurationEdit
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 settingsEdit
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 equationsEdit
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 reportingEdit
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 readingEdit
The Math extension can do much more, beside the basics described here. Check out Extension:Math/advancedSettings for old versions and further information.

This extension is being used on one or more Wikimedia projects. This probably means that the extension is stable and works well enough to be used by such high-traffic websites. Look for this extension's name in Wikimedia's CommonSettings.php and InitialiseSettings.php configuration files to see where it's installed. A full list of the extensions installed on a particular wiki can be seen on the wiki's Special:Version page. |
