Extension:SimpleMathJax

The SimpleMathJax extension enables MathJax, a JavaScript library, for typesetting TeX formula in MediaWiki inside math environments. This extension will load resources from cdnjs.cloudflare.com 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.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension() If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'SimpleMathJax' );, you need to use:

require_once "$IP/extensions/SimpleMathJax/SimpleMathJax.php";

Or you can git clone.

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

If you want to use not CDN but local mathjax scripts, you can use git clone recursive. ( In most cases, CDN is much faster than your server. )

$ 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 $wgSmjSize = 110; might be all you need to make it Just Work™.

Version	Setting name	Default value	Description
0.6.1+	$wgSmjSize	`110`	The default font size for SimpleMathJax
0.7.0+	$wgSmjUseCDN	`true`	Using CDN or Local resource
0.7.0+	$wgSmjUseChem	`true`	enable `<chem>` tags ( defaults to use chem tags )
0.6.1+	$wgSmjInlineMath	`[]`	can add some additional inlineMath symbols pairs
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 $wgSmjSize like below.

wfLoadExtension( 'SimpleMathJax' );
$wgSmjSize = 150;

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

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

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

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