By default markdown2.py's processing attempts to produce output exactly as defined by http://daringfireball.net/projects/markdown/syntax -- the "Markdown core." However, a few optional extras are also provided.

Implemented Extras

• CodeFriendly: Disable _ and __ for em and strong.
• Footnotes: support footnotes as in use on daringfireball.net and implemented in other Markdown processors (tho not in Markdown.pl v1.0.1).
• CodeColor: Pygments-based syntax coloring of <code> sections.
• LinkPatterns: Auto-link given regex patterns in text (e.g. bug number references, revision number references).
• CuddledLists: Allow lists to be cuddled to the preceding paragraph.
• pyshell: Treats unindented Python interactive shell sessions as <code> blocks. (TODO: wiki page for this)
• xml: Passes one-liner processing instructions and namespaced XML tags. (TODO: wiki page for this)

How to turn on extras

Extras are all off by default and turned on as follows on the command line:

python markdown2.py --extras name1,name2 ...

and via the module interface:

>>> import markdown2
>>> html = markdown2.markdown_path(path, ..., extras=["name1", "name2"])
>>> html = markdown2.markdown("some markdown", ..., extras=["name1", "name2"])

>>> markdowner = Markdown(..., extras=["name1", "name2"])
>>> markdowner.convert("*boo!*")
<em>boo!</em>

(New in v1.0.1.2) You can also now specify extras via the "markdown-extras" emacs-style local variable in the markdown text:

<!-- markdown-extras: code-friendly, footnotes -->
This markdown text will be converted with the "code-friendly" and "footnotes"
extras enabled.

or:

This markdown text will be converted with the "code-friendly" and "footnotes"
extras enabled.
