# PyMdown Extensions

## Overview

PyMdown Extensions is a collection of extensions for Python Markdown. They were originally written to make writing documentation more enjoyable. They cover a wide range of solutions, and while not every extension is needed by all people, there is usually at least one useful extension for everybody.

## Usage

All extensions are found under the module namespace of pymdownx. Assuming we wanted to specify the use of the MagicLink extension, we would include it in Python Markdown like so:

>>> import markdown


Check out documentation on each extension to learn more about how to configure and use each one.

Reminder

Please read the Usage Notes for information on extension compatibility and general notes to be aware of when using these extensions.

## Extensions

Arithmatex

Arithmatex is an extension that preserves LaTeX math equations ($$\frac{\sqrt x}{y^3}$$) during the Markdown conversion process so that they can be used with MathJax.

B64

B64 converts all local images in a document to base64 encoding and embeds them in the document.

BetterEm

BetterEm is a different approach to emphasis than Python Markdown's default. It works similar but handles certain corner cases differently.

Caret

Caret is an extension that is syntactically built around the ^ character. It adds support for inserting superscripts and adds an easy way to place text in an <ins> tag.

Critic

Critic adds handling and support of Critic Markup.

Details

Details creates collapsible elements with <details><summary> tags.

Emoji

Emoji makes adding emoji via Markdown easy .

EscapeAll

EscapeAll allows the escaping of any character, some with additional effects. Check it out to learn more.

Extra

Extra is just like Python Markdown's Extra package except it uses PyMdown Extensions to substitute similar extensions.

Highlight

Highlight allows you to configure the syntax highlighting of SuperFences and InlineHilite. Also passes standard Markdown indented code blocks through the syntax highlighter.

InlineHilite

InlineHilite highlights inline code: from module import function as func.

Keys

Keys makes inserting key inputs into documents as easy as pressing CtrlAltDel.

MagicLink linkafies URL and email links without having to wrap them in Markdown syntax. Also, shortens repository issue, pull request, and commit links automatically for popular code hosting providers. You can even use special shorthand syntax to link to issues, diffs, and even mention people

Mark

Mark allows you to mark words easily.

PathConverter

PathConverter converts paths to absolute or relative to a given base path.

ProgressBar

ProgressBar creates progress bars quick and easy.

SaneHeaders modifies hash headers to only be evaluated if the starting hash symbols are followed by at least one space. This is useful if you use other extensions that also use the hash symbol (like our own MagicLink extension).

SmartSymbols

SmartSymbols inserts commonly used Unicode characters via simple ASCII representations: =/= → ≠.

Snippets

Snippets include other Markdown or HTML snippets into the current Markdown file being parsed.

StripHTML

StripHTML can strip out HTML comments and specific tag attributes.

SuperFences

SuperFences is like Python Markdown's fences, but better. Nest fences under lists, admonitions, and other syntaxes. You can even create special custom fences for content like UML.
