Use with Sphinx

Add dargs.sphinx to the extensions of conf.py:

extensions = [
    'dargs.sphinx',
]

Then dargs directive will be enabled:

.. dargs::
   :module: dargs.sphinx
   :func: _test_argument

where _test_argument returns an Argument. A list of Argument is also accepted. The documentation will be rendered as:

test:

type: str

argument path: test

This argument is only used to test.
