### Where?
- Project Page: <http://code.google.com/p/python-markdown2/>
- PyPI: <http://pypi.python.org/pypi/markdown2/>
### What's new?
%(whatsnew)s
Full changelog: <http://code.google.com/p/python-markdown2/source/browse/trunk/CHANGES.txt>
### What is 'markdown2'?
`markdown2.py` is a fast and complete Python implementation of
[Markdown](http://daringfireball.net/projects/markdown/) -- a
text-to-HTML markup syntax.
### Module usage
>>> import markdown2
>>> markdown2.markdown("*boo!*") # or use `html = markdown_path(PATH)`
u'<p><em>boo!</em></p>\n'
>>> markdowner = Markdown()
>>> markdowner.convert("*boo!*")
u'<p><em>boo!</em></p>\n'
>>> markdowner.convert("**boom!**")
u'<p><strong>boom!</strong></p>\n'
### Command line usage
$ cat hi.markdown
# Hello World!
$ markdown2 hi.markdown
<h1>Hello World!</h1>
This implementation of Markdown implements the full "core" syntax plus a
number of extras (e.g., code syntax coloring, footnotes) as described on
<http://code.google.com/p/python-markdown2/wiki/Extras>.
Cheers,
Trent

"""_paths_from_path_patterns([<path-patterns>, ...]) -> file paths
Generate a list of paths (files and/or dirs) represented by the given path
patterns.
"path_patterns" is a list of paths optionally using the '*', '?' and
'[seq]' glob patterns.
"files" is boolean (default True) indicating if file paths
should be yielded
"dirs" is string indicating under what conditions dirs are
yielded. It must be one of:
never (default) never yield dirs
always yield all dirs matching given patterns
if-not-recursive only yield dirs for invocations when
recursive=False
See use cases below for more details.
"recursive" is boolean (default True) indicating if paths should
be recursively yielded under given dirs.
"includes" is a list of file patterns to include in recursive
searches.
"excludes" is a list of file and dir patterns to exclude.
(Note: This is slightly different than GNU grep's --exclude
option which only excludes *files*. I.e. you cannot exclude
a ".svn" dir.)
"on_error" is an error callback called when a given path pattern
matches nothing:
on_error(PATH_PATTERN)
If not specified, the default is look for a "log" global and
call:
log.error("`%s': No such file or directory")
Specify None to do nothing.
Typically this is useful for a command-line tool that takes a list
of paths as arguments. (For Unix-heads: the shell on Windows does
NOT expand glob chars, that is left to the app.)
Use case #1: like `grep -r`
{files=True, dirs='never', recursive=(if '-r' in opts)}
script FILE # yield FILE, else call on_error(FILE)
script DIR # yield nothing
script PATH* # yield all files matching PATH*; if none,
# call on_error(PATH*) callback
script -r DIR # yield files (not dirs) recursively under DIR
script -r PATH* # yield files matching PATH* and files recursively
# under dirs matching PATH*; if none, call
# on_error(PATH*) callback
Use case #2: like `file -r` (if it had a recursive option)
{files=True, dirs='if-not-recursive', recursive=(if '-r' in opts)}
script FILE # yield FILE, else call on_error(FILE)
script DIR # yield DIR, else call on_error(DIR)
script PATH* # yield all files and dirs matching PATH*; if none,
# call on_error(PATH*) callback
script -r DIR # yield files (not dirs) recursively under DIR
script -r PATH* # yield files matching PATH* and files recursively
# under dirs matching PATH*; if none, call
# on_error(PATH*) callback
Use case #3: kind of like `find .`
{files=True, dirs='always', recursive=(if '-r' in opts)}
script FILE # yield FILE, else call on_error(FILE)
script DIR # yield DIR, else call on_error(DIR)
