Math extension for Python-Markdown

This extension adds math formulas support to Python-Markdown.

Installation

Install from PyPI

$ pip install python-markdown-math

Install locally

Use setup.py build and setup.py install to build and install this extension, respectively.

The extension name is mdx_math, so you need to add that name to your list of Python-Markdown extensions. Check Python-Markdown documentation for details on how to load extensions.

Usage

To use this extension, you need to include MathJax library in HTML files, like:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js">
</script>

(replace 2.7.2 with the latest version if it is available).

Also, you need to specify a configuration for MathJax. Please note that most of standard configuratons include tex2jax extension, which is not needed with this code.

Example of MathJax configuration:

<script type="text/x-mathjax-config">
MathJax.Hub.Config({
  config: ["MMLorHTML.js"],
  jax: ["input/TeX", "output/HTML-CSS", "output/NativeMML"],
  extensions: ["MathMenu.js", "MathZoom.js"]
});
</script>

To pass the extension to Python-Markdown, use mdx_math as extension name. For example:

>>> md = markdown.Markdown(extensions=['mdx_math'])
>>> md.convert('$$e^x$$')
'<p>\n<script type="math/tex; mode=display">e^x</script>\n</p>'

Usage from the command line:

$ echo "\(e^x\)" | python3 -m markdown -x mdx_math
<p>
<script type="math/tex">e^x</script>
</p>

Math Delimiters

For inline math, use $...$.

For standalone math, use $$...$$, \[...\] or \begin...\end.

The single-dollar delimiter ( $...$ ) for inline math is disabled by default, but can be enabled by passing enable_dollar_delimiter=True in the extension configuration.

If you want to this extension to generate a preview node (which will be shown when MathJax has not yet processed the node, or when JavaScript is unavailable), use add_preview=True configuration option.

Notes

If you use ReText, this extension is not needed as it is included by default.
