The SimpleMathJax extension enables MathJax, a Javascript library, for typesetting TeX formula in MediaWiki inside math environments.

# Installation
|
|
* git clone in extensions directory
|
|
* Using CDN is recommended. Because it's much faster than using local resources in most cases. ("the benefits of using a CDN")
|
|
```Bash
|
|
$ git clone https://github.com/jmnote/SimpleMathJax.git
|
|
```
|
|
|
|
* (Optional) If you want to use not CDN but local mathjax scripts, you can use git clone recursive.
|
|
```Bash
|
|
$ git clone --recursive https://github.com/jmnote/SimpleMathJax.git
|
|
```
|
|
|
|
* LocalSetting.php
|
|
```PHP
|
|
wfLoadExtension( 'SimpleMathJax' );
|
|
```

# Hooks
|
|
The hook `SimpleMathJaxAttributes` is available to add attributes to the span around the math. This hook provides you with the opportunity to ensure that your own code does not interfere with MathJax's rendering of math.
|
|
|
|
For instance, if Lingo's JS functions are called before MathJax is invoked, then it is possible that Lingo will change the text so that MathJax could no longer render the math.
|
|
|
|
Lingo understands that [it should not touch anything inside an element with the class `noglossary`](https://www.mediawiki.org/wiki/Extension:Lingo#Excluding_text_from_markup) so the following code can be used to keep Lingo from ruining math:
|
|
```PHP
|
|
$wfHook['SimpleMathJaxAttributes']
|
|
= function ( array &attributes, string $tex ) {
|
|
$attributes['class'] = 'noglossary';
|
|
}
|
|
```
