The SimpleMathJax3 extension enables MathJax v3 for typesetting TeX formula in MediaWiki inside math environments.

Features

• Displays <math> and </math> symbols
  • Supports display="block", display="inline", and unspecified modes.

Installation

1. git clone to your extensions directory

git clone git@github.com:dli7319/SimpleMathJax3.git

2. Load the extension by editing LocalSettings.php

wfLoadExtension( 'SimpleMathJax3' );

3. (Optional) If not using the CDN

• Set $wgSmjUseCDN=false in LocalSettings.php.
• Clone the submodule with git submodule update --recursive --init.

Settings

Setting name	Default value	Description
$wgSmjScale	1.0	Use chtml font scale
$wgSmjUseCDN	true	Use CDN or local scripts
$wgSmjUseChem	true	Enable chem tag
$wgSmjInlineMath	[["\\(","\\)"]]	Inline math symbols pairs
$wgSmjDisplayMath	[["\\[","\\]"],["$$","$$"]]	Display math symbols pairs
$wgSmjShowMathMenu	true	Enable MathJax context menu

Notes

• $wgSmjConvertMath will allow you to use your existing LaTeX math without editing your mediawiki pages. However, this will prevent you from using the MathML syntax with MathJax.
• Do not use $wgSmjConvertMath with the Visual Editor if you want to keep <math> elements.

Development

• Edit src/ext.Smj3.js
• Run npm build
