The SimpleMathJax extension enables MathJax, a JavaScript library, for typesetting TeX formula in MediaWiki inside math environments. This extension will load resources from cdn.jsdelivr.net on all wiki pages that have math or chem tags.

<math>E=mc^2</math>

Advantages

Simple
Lightweight
UTF-8 Support
Mobile View OK
Setting Font Size
chem tag support for chemistry
additional inlineMath symbols pairs support
MediaWiki Style! Look at the samples.

InstallationEdit

Download and place the file(s) in a directory called SimpleMathJax in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php :
```
wfLoadExtension( 'SimpleMathJax' );
```
If necessary configure at your convenience
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Or you can git clone.

$ git clone https://github.com/jmnote/SimpleMathJax.git

If you want to use local MathJax scripts (and not a CDN), then you can use git clone recursive. In most cases, CDN is much faster than your server. However, a CDN may not be available if you have a hardened PHP installation due to disabled_functions restrictions.

$ git clone --recursive https://github.com/jmnote/SimpleMathJax.git

SimpleMathJax is meant to be used as an alternative to the Math extension. If the Math extension is installed it may take precedence and cause SimpleMathJax to not work. The SimpleMathJax extension is the only thing you need to start rendering equations.

Configuration settingsEdit

The following variables can be defined in LocalSettings.php after calling wfLoadExtension( 'SimpleMathJax' );. Note that for a simple site adding $wgSmjScale = 1.1; might be all you need to make it Just Work™.

Version	Setting name	Default value	Description
0.7.0+	$wgSmjUseCdn	`true`	Using CDN or Local resource
0.7.0+	$wgSmjUseChem	`true`	enable `‎<chem>` tags ( defaults to use chem tags )
0.8.0+	$wgSmjEnableMenu	`true`	Make MathJax context menu available This setting is missed since 0.8.0; it would be a mistake
0.8.0+	$wgSmjExtraInlineMath	`[]`	can add some additional inlineMath symbols pairs
0.8.1+	$wgSmjScale	`1`	The default font size for SimpleMathJax
0.7.4	$wgSmjShowMathMenu	false	(removed) (replaced by $wgSmjEnableMenu)
0.6.1	$wgSmjSize	110	(removed) (replaced by $wgSmjScale)
0.6.1	$wgSmjInlineMath	[]	(removed) (replaced by $wgSmjExtraInlineMath)
0.6.1	$wgSmjDisableChem	false	(removed) (replaced by $wgSmjUseChem)
0.6.1	$wgSmjScripts	['//cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-AMS-MML_HTMLorMML', '//cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/extensions/TeX/mhchem.js']	(removed) (replaced by $wgSmjUseCDN) can use local or another remote scripts ( defaults to use cloudflare CDN )
0.6	$wgSimpleMathJaxSize	125	(removed) (replaced by $wgSmjSize)
0.6	$wgSimpleMathJaxUseCDN	true	(removed) (replaced by $wgSmjScripts)
0.6	$wgSimpleMathInlineMath	[]	(removed) (replaced by $wgSmjInlineMath)

If you want to change font size, set $wgSmjScale like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjScale = 1.5;

If you want to enable some additional inlineMath symbol pairs, set $wgSmjExtraInlineMath like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjExtraInlineMath = [ [ "$", "$" ], [ "\\(", "\\)" ] ];

If you want to use local module, set $wgSmjUseCdn like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjUseCdn = false;

SimpleMathJax and Live Preview (versions < 0.8.0)Edit

Prior to version 0.8.0, the following had to be added to MediaWiki:Common.js in order to have the Live Preview in the editor show rendered math output instead of raw LaTeX source code:

function waitForMathJax($content) {
  if (typeof MathJax === 'undefined') {
    setTimeout(function () { waitForMathJax($content); }, 1000);
  } else {
    MathJax.Hub.Queue(["Typeset", MathJax.Hub, $content[0]]).execute();
  }
}

mw.hook('wikipage.content').add(waitForMathJax);
