Release v2.1.0

Changelog

[v2.1.0]

Added

• Ability to ignore ANN001 errors for specific argument names #68 Add --suppress-dummy-args configuration option to suppress ANN000 level errors for dummy arguments, defined as "_"

Additional Details

This release adds the opinionated --suppress-dummy-args flag, as requested by #68. If this flag is set, TYP000-level errors are suppressed for "dummy" arguments, defined as _.

For example:

def foo(a: int, _) -> None:
    """This is a test function."""
    ...

Would not yield an ANN001 error for the dummy argument:

$ flake8 test.py
test.py:1:17: ANN001 Missing type annotation for function argument '_'
$ flake8 test.py --suppress-dummy-args
<No output>

The default value of this configuration option is False, so this addition should be transparent to existing users.

Also added in this PR are the pre-commit hooks to CI, as also done with the other repos in the organization. As part of this change, the explicit Flake8 step is removed, as the pre-commit hooks already run Flake8. The pre-commit hooks are also tied to a conditional to only run it in a single build environment, Python 3.8, rather than across all of them.

Closes #68

You don't want to cache the pre-commit cache in CI?

I guess that would probably be helpful, oops 😄
