import CommonMark

CommonMark.commonmark('*hello!*')

# Or, without the syntactic sugar:
parser = CommonMark.Parser()
renderer = CommonMark.HtmlRenderer()
ast = parser.parse("Hello *World*")
html = renderer.render(ast)
json = CommonMark.ASTtoJSON(ast)
CommonMark.dumpAST(ast) # pretty print generated AST structure
print(html) # <p>Hello <em>World</em><p/>

----- or -----

rolands@kamaji:~$ cmark.py README.md -o README.html
rolands@kamaji:~$ cmark.py README.md -o README.json -aj # output AST as JSON
rolands@kamaji:~$ cmark.py README.md -a # pretty print generated AST structure
rolands@kamaji:~$ cmark.py -h

Contributing

If you would like to offer suggestions/optimizations/bugfixes through pull requests please do! Also if you find an error in the parser/renderer that isn’t caught by the current test suite please open a new issue and I would also suggest you send the commonmark.js project a pull request adding your test to the existing test suite.

Tests

To work on CommonMark-py, you will need to be able to run the test suite to make sure your changes don’t break anything. To run the tests, you can do something like this:

$ pyvenv venv
$ ./venv/bin/python setup.py develop test

The tests script, run_spec_tests.py, is pretty much a devtool. As well as running all the tests embedded in spec.txt it also allows you to run specific tests using the -t argument, provide information about passed tests with -p, percentage passed by category of test with -s, and enter markdown interactively with -i (In interactive mode end a block by inputting a line with just end, to quit do the same but with quit). -d can be used to print call tracing.

rolands@kamaji:~/utils/CommonMark-py$ python run_spec_tests.py -h
usage: run_spec_tests.py [-h] [-t T] [-p] [-f] [-i] [-d] [-np] [-s]

script to run the CommonMark specification tests against the CommonMark.py
parser

optional arguments:
  -h, --help  show this help message and exit
  -t T        Single test to run or comma separated list of tests (-t 10 or -t 10,11,12,13)
  -p          Print passed test information
  -f          Print failed tests (during -np...)
  -i          Interactive Markdown input mode
  -d          Debug, trace calls
  -np         Only print section header, tick, or cross
  -s          Print percent of tests passed by category
