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).

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.
