An overview of what can currently be done with this extension is found at the English Wikipedia's documentation. This article documents how to install, configure and test recent versions of this extension. For advanced usages and documentation of old versions refer to Extension:Math/advancedSettings. ## Viewing math The Math extension tries to deliver MathML output, with fallback to SVG or PNG images respectively. Depending on the capabilities of the device you are using, the sort of output is chosen. Basic math support works for all browsers. However, for optimal rendering specific tuning may be needed: ## Installation • If using Vagrant, install with vagrant enable-role math && vagrant provision Manual installation • Download and place the file(s) in a directory called Math in your extensions/ 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.

## Configuration

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 MathML as default rendering option
$wgDefaultUserOptions['math'] = 'mathml';$wgMathFullRestbaseURL= 'https://api.formulasearchengine.com/';


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

Navigate to https://en.wikipedia.org/wiki/Special:MathStatus where you should replace en.wikipedia.org with the hostname of your wiki. If that does not work create a task on https://phabricator.wikimedia.org

## List of significant configuration settings

Setting name Default value Description
$wgMathValidModes array( 'png', 'source', 'mathml' ) Defines the mode allowed on the server.$wgMathDisableTexFilter 'never' Option to disable the tex filter. If set to true any LaTeX espression 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. Use "always" to disable this feature.

## 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.
