# PyMdown Extensions [PyMdown Extensions][1] is a collection of Markdown extensions that add some great features to the standard Markdown library. For this reason, the **installation of this package is highly recommended** as it's well-integrated with the Material theme. [1]: http://facelessuser.github.io/pymdown-extensions/ ## Installation The PyMdown Extensions package can be installed with the following command: ``` sh pip install pymdown-extensions ``` The following list of extensions that are part of the PyMdown Extensions package are recommended to be used together with the Material theme: ``` yaml markdown_extensions: - pymdownx.arithmatex - pymdownx.betterem: smart_enable: all - pymdownx.caret - pymdownx.critic - pymdownx.details - pymdownx.emoji: emoji_generator: !!python/name:pymdownx.emoji.to_svg - pymdownx.inlinehilite - pymdownx.magiclink - pymdownx.mark - pymdownx.smartsymbols - pymdownx.superfences - pymdownx.tasklist: custom_checkbox: true - pymdownx.tilde ``` ## Usage ### Arithmatex MathJax [Arithmatex][2] integrates Material with [MathJax][3] which parses block-style and inline equations written in TeX markup and outputs them in mathematical notation. See [this thread][4] 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 must be done with [additional JavaScript][5]: ``` yaml 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 in `extra_javascript` which contains your MathJax configuration, e.g.: ``` js 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" }; ``` In your `mkdocs.yml`, include it with: ``` yaml extra_javascript: - 'javascripts/extra.js' - 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-MML-AM_CHTML' ``` [2]: https://facelessuser.github.io/pymdown-extensions/extensions/arithmatex/ [3]: https://www.mathjax.org/ [4]: http://meta.math.stackexchange.com/questions/5020/ [5]: ../customization.md#additional-javascript #### Blocks Blocks are enclosed in `:::tex $$...$$` which are placed on separate lines. Example: ``` tex $$ \frac{n!}{k!(n-k)!} = \binom{n}{k} $$ ``` Result: $$ \frac{n!}{k!(n-k)!} = \binom{n}{k} $$ #### Inline Inline equations need to be enclosed in `:::tex $...$`: Example: ``` tex 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][6] 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][7]. [6]: https://facelessuser.github.io/pymdown-extensions/extensions/betterem/ [7]: https://facelessuser.github.io/pymdown-extensions/usage_notes/ ### Caret [Caret][8] makes it possible to highlight ^^inserted text^^. The portion of text that should be marked as added must be enclosed in two carets `^^...^^`. [8]: https://facelessuser.github.io/pymdown-extensions/extensions/caret/ ### Critic [Critic][9] implements [Critic Markup][10], 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. ==} [9]: https://facelessuser.github.io/pymdown-extensions/extensions/critic/ [10]: http://criticmarkup.com/ ### Details [Details][11] adds collapsible [Admonition-style blocks][12] 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. [11]: https://facelessuser.github.io/pymdown-extensions/extensions/details/ [12]: admonition.md ### Emoji [Emoji][13] adds the ability to insert a :shit:-load of emojis that we use in our daily lives. See the [EmojiOne demo][14] for a list of all available emojis.

It's useful for short snippets included within body copy, e.g. `#!js var test = 0;` and can be achived by prefixing inline code with a shebang and language identifier, e.g. `#!js`. [18]: https://facelessuser.github.io/pymdown-extensions/extensions/inlinehilite/ ### MagicLink [MagicLink][19] 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. [19]: https://facelessuser.github.io/pymdown-extensions/extensions/magiclink/ ### Mark [Mark][20] 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 `==...==`. [20]: https://facelessuser.github.io/pymdown-extensions/extensions/mark/ ### SmartSymbols [SmartSymbols][21] 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, ...). [21]: https://facelessuser.github.io/pymdown-extensions/extensions/smartsymbols/ ### SuperFences [SuperFences][22] provides the ability to nest code blocks under blockquotes, lists and other block elements, which the [Fenced Code Blocks][23] extension from the standard Markdown library doesn't parse correctly. [22]: https://facelessuser.github.io/pymdown-extensions/extensions/superfences/ [23]: https://python-markdown.github.io/extensions/fenced_code_blocks/ ### Tasklist [Tasklist][24] 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: ``` markdown * [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: * [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 [24]: https://facelessuser.github.io/pymdown-extensions/extensions/tasklist/ ### Tilde [Tilde][25] 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.
