|''Name''|PluginMathJax|
|''Description''|Displays TeX math using MathJax|
|''Author''|[[Canada East|http://tiddlywiki.canada-east.ca/]]|
|''Version''|1.4.1|
|''Date''|2010-10-18|
|''CodeRepository''|[[PluginMathJax|http://tiddlywiki.canada-east.ca/#PluginMathJax]]|
|''CoreVersion''|[[2.6.1|http://www.tiddlywiki.com]]|

|''Feedback''|[[Contact|https://spreadsheets.google.com/viewform?formkey=dGg2RkpxZW5zWTh6QjZxOXgzZUlfakE6MQ]]|
!Description
This plugin uses [[MathJax|http://www.mathjax.org/]] to typeset ([[AMS|http://www.ams.org/publications/authors/tex/amslatex]]) [[LaTeX|http://www.latex-project.org/]] math. It can also be configured to use additional MathJax functionality.
>"MathJax is an open source JavaScript display engine for mathematics that works in all modern browsers."
!Notes
Right click any math display for a MathJax menu. The user can select the renderer and zoom settings. It performs best in [[Webkit|http://en.wikipedia.org/wiki/List_of_web_browsers#WebKit-based_browsers]] based browsers. Larger math displays such as the additional examples tiddler below can put quite a load on IE. PluginMathJax was inspired by : [[Plugin: jsMath|http://bob.mcelrath.org/tiddlyjsmath.html]]
!Installation
#''Backup'' your TiddlyWiki!
#Uninstall or remove systemConfig tag from Plugin: jsMath if it is installed.
#It is required that the MathJax directory is installed in '''js/MathJax/''' in the same location as the TiddlyWiki html file.<br>(Or edit the script source where commented in the plugin code below after installation to match the location of your MathJax install.)
#Install this plugin (and examples tiddler linked below if desired).
!Usage
|!Style|!Source|!Output|
|Inline &nbsp;&nbsp;&nbsp;|{{{The variable <math>x</math> is real.}}}|The variable <math>x</math> is real.|
|~|{{{The variable \(y\) is complex.}}}|The variable \(y\) is complex.|
|Block &nbsp;&nbsp;&nbsp;|{{{This \[\int_a^b x = \frac{1}{2}(b^2-a^2)\] is an easy integral.}}}|This \[\int_a^b x = \frac{1}{2}(b^2-a^2)\] is an easy integral.|
|~|{{{This $$\int_a^b \sin x = -(\cos b - \cos a)$$ is another easy integral.}}}|This $$\int_a^b \sin x = -(\cos b - \cos a)$$ is another easy integral.|

!Examples

!Configuration
MathJax can be manually configured if desired by editing the code below (advanced). See the [[MathJax documentation|http://www.mathjax.org/resources/docs/?configuration.html#configuration-options-by-component]] for details.
!Revision History
*v1.4.1, 2010-10-18, minor change to createTiddlyElement call and added SyntaxHighlighter tags to code section.
*v1.4, 2010-10-09, re-wrote wikifiers, archived [[previous version|PluginMathJax v1.3]] (Plugin: jsMath - compatible).
*v1.3, 2010-10-07, returned to wikifiers design avoiding autoLink WikiWords conflict, kept modified wikify and recommended way of loading MathJax dynamically, removed the tex2jax extension and corrected several browser compatibility issues (InnerHTML for Opera and IE9).
*v1.2, 2010-10-05, removed some redundant MathJax config entries, moved modified wikify and MathJax.Hub.Queue call.
*v1.1, 2010-10-03, autoLinkWikiWords disabled in absence of DisableWikiLinksPlugin, modifed wikify.
*v1.0, 2010-09-26, Initial Release
