PyMdown Extensions

PyMdown Extensions is a collection of Markdown extensions that add some great missing features to the standard Markdown library. A compatible version is always included with the theme.

Configuration

The following list of extensions that are part of the PyMdown Extensions package are recommended to be used together with Material for MkDocs:

markdown_extensions:
  - pymdownx.arithmatex
  - pymdownx.betterem:
      smart_enable: all
  - pymdownx.caret
  - pymdownx.critic
  - pymdownx.details
  - pymdownx.emoji:
      emoji_index: !!python/name:pymdownx.emoji.twemoji
      emoji_generator: !!python/name:pymdownx.emoji.to_svg
  - pymdownx.inlinehilite
  - pymdownx.magiclink
  - pymdownx.mark
  - pymdownx.smartsymbols
  - pymdownx.superfences

      custom_checkbox: true
  - pymdownx.tabbed
  - pymdownx.tilde

Usage

Arithmatex MathJax

Arithmatex integrates Material for MkDocs with MathJax which parses block-style and inline equations written in TeX markup and outputs them in mathematical notation. See this thread for a short introduction and quick reference on how to write equations in TeX syntax.

Besides activating the extension in the mkdocs.yml, the MathJax JavaScript runtime needs to be included. This can be done with additional JavaScript:

extra_javascript:
  - https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-MML-AM_CHTML

If you want to override the default MathJax configuration, you can do this by adding another JavaScript file before the MathJax runtime which contains the MathJax configuration, e.g.:

window.MathJax = {
  tex2jax: {
    inlineMath: [ ["\\(","\\)"] ],
    displayMath: [ ["\\[","\\]"] ]
  },
  TeX: {
    TagSide: "right",
    TagIndent: ".8em",
    MultLineWidth: "85%",
    equationNumbers: {
      autoNumber: "AMS",
    },
    unicode: {
      fonts: "STIXGeneral,'Arial Unicode MS'"
    }
  },
  displayAlign: "left",
  showProcessingMessages: false,
  messageStyle: "none"
};

Then, add the following lines to mkdocs.yml:

extra_javascript:
  - javascripts/extra.js
  - https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-MML-AM_CHTML

Blocks

Blocks are enclosed in :::tex $$...$$ which are placed on separate lines.

Example:

$$
\frac{n!}{k!(n-k)!} = \binom{n}{k}
$$

Result:

\frac{n!}{k!(n-k)!} = \binom{n}{k}

Inline

Inline equations must be enclosed in :::tex $...$:

Example:

Lorem ipsum dolor sit amet: $p(x|y) = \frac{p(y|x)p(x)}{p(y)}$

Result:

Lorem ipsum dolor sit amet: p(x|y) = \frac{p(y|x)p(x)}{p(y)}

BetterEm

BetterEm improves the handling of emphasis markup (bold and italic) within Markdown by providing a more sophisticated parser for better detecting start and end tokens. Read the documentation for usage notes.

Caret

Caret makes it possible to highlight ^^inserted text^^. The portion of text that should be marked as added must be enclosed in two carets ^^...^^.

Critic

Critic implements Critic Markup, a Markdown extension that enables the tracking of changes (additions, deletions and comments) on documents. During compilation of the Markdown document, changes can be rendered (default), accepted or rejected.

Text can be {--deleted--} and replacement text {++added++}. This can also be combined into {one~>a single} operation. {==Highlighting==} is also possible {>>and comments can be added inline<<}.

{==

Formatting can also be applied to blocks, by putting the opening and closing tags on separate lines and adding new lines between the tags and the content.

==}

Details

Details adds collapsible Admonition blocks which can contain arbitrary content using the HTML5 details and summary tags. Additionally, all Admonition qualifiers can be used, e.g. note, question, warning etc.:

??? question "How many Prolog programmers does it take to change a lightbulb?"

Yes.

Emoji 🎉

Emoji adds the ability to insert, well, emojis! 😄

By default, Emoji uses JoyPixles' emoji under the former name EmojiOne. Recent versions of the extension lock support to an older version (2.2.7) due to JoyPixels' newer, less permissible licenses included in later releases. This restricts support to Unicode 9. To get the latest support for the current Unicode version, you can use Twemoji instead which has a much more permissable license. Simply override the default emoji index being used:

markdown_extensions:
  - pymdownx.emoji:
      emoji_index: !!python/name:pymdownx.emoji.twemoji
      emoji_generator: !!python/name:pymdownx.emoji.to_svg

To view all the available short names and emoji available, see Emoji's documentation on your chosen index which includes links to the files containing the short names and emoji associated with each supported index.

In addition, you can access all the Material icons and Fontawesome icons by using Material for MkDocs's custom emoji index. It extends the Twemoji index with new short names that access any of the included icons. To use the custom index, you need to use the following options when including the Emoji extension:

  - pymdownx.emoji:
      emoji_index: !!python/name:material.emoji.material
      emoji_generator: !!python/name:material.emoji.to_svg

Then we can access any of the icons:

=== "Markdown" ``` We can use Material Icons :material-airplane:.

We can also use Fontawesome Icons :fontawesome-solid-ambulance:.

That's not all, we can also use Octicons :octicons-octoface:.
```

=== "Results" We can use Material Icons :material-airplane:.

We can also use Fontawesome Icons :fontawesome-solid-ambulance:.

That's not all, we can also use Octicons :octicons-octoface:.

InlineHilite

InlineHilite adds support for inline code highlighting. It's useful for short snippets included within body copy, e.g. #!js var test = 0; and can be activated by prefixing inline code with a shebang and language identifier, e.g. #!js.

MagicLink

MagicLink detects links in Markdown and auto-generates the necessary markup, so no special syntax is required. It auto-links http[s]:// and ftp:// links, as well as references to email addresses.

Mark

Mark adds the ability to ==highlight text== like it was marked with a ==text marker==. The portion of text that should be highlighted must be enclosed in two equal signs ==...==.

SmartSymbols

SmartSymbols converts markup for special characters into their corresponding symbols, e.g. arrows (<--, -->, <-->), trademark and copyright symbols ((c), (tm), (r)) and fractions (1/2, 1/4, ...).

SuperFences

SuperFences provides the ability to nest code blocks under blockquotes, lists and other block elements, which the Fenced Code Blocks extension from the standard Markdown library doesn't parse correctly.

SuperFences does also allow grouping code blocks with tabs.

Tabbed

Tabbed adds support for creating tabbed groups of Markdown content.

Example:

=== "Fruit List"
    - :apple: Apple
    - :banana: Banana
    - :kiwi: Kiwi

=== "Fruit Table"
    Fruit           | Color
    --------------- | -----
    :apple:  Apple  | Red
    :banana: Banana | Yellow
    :kiwi:   Kiwi   | Green

Result:

=== "Fruit List" - 🍎 Apple - 🍌 Banana - :kiwi: Kiwi

=== "Fruit Table" Fruit | Color --------------- | ----- 🍎 Apple | Red 🍌 Banana | Yellow :kiwi: Kiwi | Green

Tasklist

Tasklist adds support for styled checkbox lists. This is useful for keeping track of tasks and showing what has been done and has yet to be done. Checkbox lists are like regular lists, but prefixed with [ ] for empty or [x] for filled checkboxes.

Example:

* [x] Lorem ipsum dolor sit amet, consectetur adipiscing elit
* [x] Nulla lobortis egestas semper
* [x] Curabitur elit nibh, euismod et ullamcorper at, iaculis feugiat est
* [ ] Vestibulum convallis sit amet nisi a tincidunt
    * [x] In hac habitasse platea dictumst
    * [x] In scelerisque nibh non dolor mollis congue sed et metus
    * [x] Sed egestas felis quis elit dapibus, ac aliquet turpis mattis
    * [ ] Praesent sed risus massa
* [ ] Aenean pretium efficitur erat, donec pharetra, ligula non scelerisque
* [ ] Nulla vel eros venenatis, imperdiet enim id, faucibus nisi

Result:

• Lorem ipsum dolor sit amet, consectetur adipiscing elit
• Nulla lobortis egestas semper
• Curabitur elit nibh, euismod et ullamcorper at, iaculis feugiat est
• Vestibulum convallis sit amet nisi a tincidunt
  • In hac habitasse platea dictumst
  • In scelerisque nibh non dolor mollis congue sed et metus
  • Sed egestas felis quis elit dapibus, ac aliquet turpis mattis
  • Praesent sed risus massa
• Aenean pretium efficitur erat, donec pharetra, ligula non scelerisque
• Nulla vel eros venenatis, imperdiet enim id, faucibus nisi

Tilde

Tilde provides an easy way to strike through cross out text. The portion of text that should be erased must be enclosed in two tildes ~~...~~ and the extension will take care of the rest.
