Convert Markdown to Google Code Wiki
Markowik is able to convert most Markdown constructs to its Google Code Wiki (GCW) equivalents. Instead of listing all supported conversions here, please have a look at Markowik’s test suite show case.
Markowik requires Python 2.6 or 2.7.
pip install markowik
You can also use Markowik without installation, as described under Contributions.
From the help output:
usage: markowik [-h] [--mx [MX [MX ...]]] [--image-baseurl URL] [--html-images] [--encoding ENCODING] [--quiet] INFILE [OUTFILE] Convert Markdown to Google Code Wiki. positional arguments: INFILE markdown file OUTFILE wiki file (default: stdout) optional arguments: -h, --help show this help message and exit --mx [MX [MX ...]] markdown extensions to activate --image-baseurl URL base URL to prepend to relative image locations --html-images always use HTML for images --encoding ENCODING encoding of input and output (default: UTF8) --quiet disable info messages
Markdown extensions may be given similarly as to the Python Markdown (PyMD) command line tool, with the exception that individual extensions must be separated by a space:
$ markowik INPUT --mx tables def_list
The currently supported (i.e. tested) extensions are abbr, tables, and def_list. Other extensions generally should work too but might yield unexpected results in the converted wiki text.
Concerning the option --html-images, see the explanations below at Caveats.
Markowik is implemented in Python. The markowik module provides a function named convert. Semantically it is similar to the command line interface (keyword arguments correspond to command line options). Here’s a short usage example:
>>> import markowik >>> markowik.convert("Some *markdown* text ...", mx=['tables']) u'Some _markdown_ text ...'
>>> src = """Summary: page summary ... Labels: some, labels ... ... Here starts the *page* .. ... """ >>> print markowik.convert(src, mx=['meta']) #summary page summary #labels some, labels <BLANKLINE> Here starts the _page_ ..
Note that the meta extension has to be enabled explicitly, i.e. by default Markowik does not recognize page pragmas.
GCW cannot express all markup possible in Markdown. This means Markdown source files should be written with the following limitations in mind.
GCW does not really support multiple nested paragraphs (e.g. in lists or blockquotes). Markowik simulates multiple nested paragraphs by separating them with a <br/> (which visually mimics paragraphs but does not break the nesting environment).
Markdown allows to express alternative and title texts for images. GCW’s image syntax does not support this. The only way to preserve these texts is to use plain HTML <img> tags. The option --html-images enables this workaround.
Another issue is that GCW expects image URLs to end with an image file type extension. Markowik adds artificial image extensions if necessary, for instance http://foo.bar/image is changed to http://foo.bar/image?x=x.png.
GCW has no markup for abbreviations nor does it support the HTML tag <abbr>. Markowik converts abbreviations to <span>-elements which kind of mimics abbreviations (in a limited fashion of course).
Any plain HTML occurring in a Markdown source ends up literally in GCW (with the exception of the content of span-level tags). This means the Markdown source should only contain HTML supported by GCW. Another implication is that URLs used in plain HTML tags are not checked for GCW compatibility. In other words: when using raw HTML you are on your own!

Markowik uses Buildout to easily set up the development environment. Buildout automates the process of downloading and installing requirements to use and develop Markowik. Requirements are installed local to the project source directory, i.e. it does not clutter the system Python installation.
In a fresh source checkout, run:
$ python bootstrap.py $ bin/buildout
When done, the following scripts can be found in the bin/ directory:
- Explicitly require PyMD 2.0.3 (this is a temporary fix until markowik correctly works with PyMD 2.1). Note: If this conflicts with requirements of other Python packages, run markowik in its own buildout as described above.
- Minor documentation tweaks.
- Improved documentation.
- Minor fixes.
- Initial release.
