# Markdown parsing library |
| 2 |
|
| 3 |
Contains two libraries: |
| 4 |
|
| 5 |
* `/extra` |
| 6 |
- Gives you `MardownExtra_Parser` and `Markdown_Parser` |
| 7 |
- Docs at http://michelf.ca/projects/php-markdown/extra/ |
| 8 |
|
| 9 |
* `/gfm` -- Github Flavored Markdown |
| 10 |
- Gives you `WPCom_GHF_Markdown_Parser` |
| 11 |
- It has the same interface as `MarkdownExtra_Parser` |
| 12 |
- Adds support for fenced code blocks: https://help.github.com/articles/creating-and-highlighting-code-blocks/#fenced-code-blocks |
| 13 |
- By default it replaces them with a code shortcode |
| 14 |
- You can change this using the `$use_code_shortcode` member variable |
| 15 |
- You can change the code shortcode wrapping with `$shortcode_start` and `$shortcode_end` member variables |
| 16 |
- The `$preserve_shortcodes` member variable will preserve all registered shortcodes untouched. Requires WordPress to be loaded for `get_shortcode_regex()` |
| 17 |
- The `$preserve_latex` member variable will preserve oldskool $latex yer-latex$ codes untouched. |
| 18 |
- The `$strip_paras` member variable will strip <p> tags because that's what WordPress likes. |
| 19 |
- See `WPCom_GHF_Markdown_Parser::__construct()` for how the above member variable defaults are set. |
