8.22 Markdown variants

In addition to pandoc’s extended Markdown, the following Markdown variants are supported:

• markdown_phpextra (PHP Markdown Extra)
• markdown_github (deprecated GitHub-Flavored Markdown)
• markdown_mmd (MultiMarkdown)
• markdown_strict (Markdown.pl)
• commonmark (CommonMark)
• gfm (Github-Flavored Markdown)
• commonmark_x (CommonMark with many pandoc extensions)

To see which extensions are supported for a given format, and which are enabled by default, you can use the command

pandoc --list-extensions=FORMAT

where FORMAT is replaced with the name of the format.

Note that the list of extensions for commonmark, gfm, and commonmark_x are defined relative to default commonmark. So, for example, backtick_code_blocks does not appear as an extension, since it is enabled by default and cannot be disabled.
