A utility for ensuring Google-style docstrings stay up to date with the source code.
Project description
A limited docstring linter which checks that function/method parameters are defined in their docstrings. Darglint expects docstrings to be formatted using the Google Python Style Guide.
Darglint is in a very early stage, and fails for a lot of things. Certain features, such as a robust command-line interface, still do not exist.
Installation
To install darglint, use pip.
pip install darglint
Or, clone the repository, cd to the directory, and
pip install .
Usage
Given a python source file, serializers.py, you would check the docstrings as follows:
darglint serializers.py
You can give an optional verbosity setting to darglint. For example,
darglint -v 3 *.py
Would give the most verbose warnings for each python module in the current directory.
Features planned and implemented
The below list is all that defines the current roadmap for darglint. It is roughly sorted in order of importance.
[x] Function definitions can be checked.
[x] Methods definitions of top-level class can be checked.
[x] Line number printout for function/method definition.
[x] Add parsing of “Returns” section, and warn if differing from function definition.
[x] Add command line interface.
[x] Add multiple options for output.
[ ] Add checks for “Raises” section, like “Args”. Any exceptions raised in the body should be documented.
[ ] Add checks for “Yields” section, like “Returns”.
[ ] Add numbers to errors, ability to silence certain errors. (Use same formatting as pycodestyle.)
[ ] Add TOML configuration file (use same interface as pydoclint, etc.)
[ ] Add type hint integration. If an argument has a type hint, then the description of the argument, if it has a type, should match that.
[ ] Add support for python versions earlier than 3.6.
[ ] Syntastic support. (Syntastic is not accepting new checkers until their next API stabilizes, so this may take some time.)
Development
Install darglint. First, clone the repository:
git clone https://github.com/terrencepreilly/darglint.git
cd into the directory, create a virtual environment (optional), then setup:
cd darglint/ virtualenv -p python3.6 .env source .env/bin/activate pip install -e .
You can run the tests using
python setup.py test
Or, install pytest manually, cd to the project’s root directory, and run
pytest
Contributions welcome.
