Monk is a lightweight, markdownish markup language for generating HTML. It's implemented in Python and can be used as both a command line utility and a Python library.
On the command line:
$ monk < input.txt > output.html
As a library:
>>> import monk >>> html = monk.render(text)
Monk inherits much of its basic syntax from Markdown:
This is a paragraph containing *emphasised* and **strong** text. It also contains `code` in backticks. This is a second paragraph containing a [link](http://example.com).
Monk differs from Markdown in supporting an extensible, indentation-based syntax for generating arbitrary HTML:
:div .outer :div .inner This is a paragraph.
Monk also includes out-of-the-box support for tables, tables-of-contents, definition lists, syntax highlighting, and footnotes.
See the documentation for details.
