mypy type hints for 3rd party modules

This folder contains type hints for 3rd party Python modules, used by mypy for static analysis of Python code.

Generation and Maintenance

The files are initially generated with stubgen from mypy. They can be generated for a whole package:

stubgen -o mypy_stubs -p package_name

They can be generated for just one module:

stubgen -o mypy_stubs -m package_name.submodule

Some Django packages require DJANGO_SETTINGS_MODULE, or stubgen will fail:

export DJANGO_SETTINGS_MODULE=privaterelay.settings
stubgen -o mypy_stubs -p package_name

The generated stubs are placeholders, and often require significant modifications to run without errors. They are also tied to the specific version of the package. For this reason, we don't require stubs for all third-party packages.

Documentation

When generating stubs, add a docstring header to the file that specifies the pip package name and header. This gives us a chance to recognize that the stub is out-of-date when updating the package.

Add the same data here:

package name	version	module name
`django-waffle`	3.0.0	`waffle`
`python-decouple`	3.6	`decouple`
