Type hints (PEP 484) support for the Sphinx autodoc extension
Project description
This extension allows you to use Python 3 annotations for documenting acceptable argument types and return value types of functions. This allows you to use type hints in a very natural fashion, allowing you to migrate from this:
def format_unit(value, unit):
"""
Formats the given value as a human readable string using the given units.
:param float|int value: a numeric value
:param str unit: the unit for the value (kg, m, etc.)
:rtype: str
"""
return '{} {}'.format(value, unit)
to this:
from typing import Union
def format_unit(value: Union[float, int], unit: str) -> str:
"""
Formats the given value as a human readable string using the given units.
:param value: a numeric value
:param unit: the unit for the value (kg, m, etc.)
"""
return '{} {}'.format(value, unit)
There is also support for google docstrings or numpy docstrings with help of the napoleon napoleon sphinx extention.
Installation and setup
First, use pip to download and install the extension:
$ pip install sphinx-autodoc-napoleon-typehints
Then, add the extension to your conf.py:
extensions = [
'sphinx.ext.autodoc',
'sphinx_autodoc_napoleon_typehints'
]
How it works
The extension listens to the autodoc-process-signature and autodoc-process-docstring Sphinx events. In the former, it strips the annotations from the function signature. In the latter, it injects the appropriate :type argname: and :rtype: directives into the docstring.
Only arguments that have an existing :param: directive in the docstring get their respective :type: directives added. The :rtype: directive is added if and only if no existing :rtype: is found.
This extension does not currently have any configuration options.
