An "--extend-fixable" option to extend on-save fixable rules with on-commit fixable rules

[lsorber]

Hi,

For the Poetry Cookiecutter template that we maintain, we'd like to be able to distinguish between two types of fixable rules:

1. IDE fixable rules: fixes that you don't mind running on-save.
2. Commit-time (or later) fixable rules: a superset of the IDE fixable rules.

Examples of rules that you don't want to run on-save (1), but that may want to run on-commit (2) are:

• ERA001: remove commented out code (e.g. you comment out a section to run a test, but don't want these to be removed)
• F401: remove unused imports (e.g. you start a new file, type import numpy as np, then hit save and see the import removed)
• T201: remove print statements (e.g. you added print statement to debug something)

Is it correct that --fixable overrides (and does not extend) the fixable setting in pyproject.toml? Is there a way to extend pyproject.toml's fixable setting with the CLI? Or would this be a new feature?

Thank you!

I think it would make sense to support --extend-fixable and --extend-unfixable, to mirror --select and --extend-select. You're right that the current version overrides the pyproject.toml.
