Addon for Friendika to include MathJax (LaTeX math syntax)
This addon lets your users use LaTeX to type mathematical formulas
within their posts. MathJax takes care about the best method for the
browser to display the formula and provides compatibility to 99%
of the modern browsers.
You can either use the MathJax CDN online, thus loading the required javascript
libraries from the MathJax cloud, or use a local installation of MathJax.
Please see the plugin settings in the admin panel for configuration possibles.
If you don't set up a local MathJax instance, leave the configuration untouched
it will fall back to the MathJax cloud as default value.
If you don't use the admin panel add mathjax to the list of active addons
$a->config['system']['addon'] = [..., mathjax, ...]
To select the source of the included javascript libraries add a line
$a->config['mathjax']['baseurl'] = 'the URL to your MathJax installation';
to your .htconfig.php file. If this line is not there, the addon assumes that
you want to use the MathJax cloud (CDN).
Please note that your usage of the CDN is governed by the "MathJax CDN Terms of
Service" see http://www.mathjax.org/download/mathjax-cdn-terms-of-service/

MathJax Addon
=============
* Author: Tobias Diekershoff
* License: [3-clause BSD](http://opensource.org/licenses/BSD-3-Clause) license
(see the LICENSE file in the addon directory)
About
-----
This addon for friendica includes the [MathJax][1] CDN to enable rendering of
[LaTeX][2] formulae in your friendica postings.
Configuration
-------------
All you need to do is provide friendica with the base URL of MathJax. This can
be either the URL of the CDN of MathJax or your own installation.
In case you want to use the CDN you can try the following URL as a quick start
http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML
In case you don't want or can use the admin panel of firneidca you can activate
the addon by adding _mathjax_ to the
$a->config['system']['addon']
list in your .htconfig.php file and then providing the base URL after that
$a->config['mathjax']['baseurl'] = 'the URL to your MathJax installation';
Usage
=====
Once the addon is configured you can use LaTeX syntax in your postings to share
formulae with your contacts. But remember that the formulae are rendered in the
browser of the user thus your contacts need to activate this addon as well. If
they don't they will only see the LaTeX syntax in your texts.
Just enclose your equations in $$...$$ pairs like e.g. $$f_c(x)=ax+b$$.
