Black: Support config in setup.cfg

[Natim]

Today, the config of black is exclusively in pyproject.toml.

However some project relies on setuptools.setup() rather than Flit.

Would it be possible to also store the config in setup.cfg?
Especially since the syntax would be the same?

[tool.black]
line-length = 99
include = \.pyi?$
exclude = \.git
          | \.hg
          | \.mypy_cache
          | \.tox
          | \.venv
          | _build
          | buck-out
          | build
          | dist

Note that other projects like zest.releaser, flake8, twine, wheel already support that.

I would be happy to contribute this, if it makes sense...

Indeed, in our project, we use the setup.cfg file to configure our package metadata, flake8 options, coverage, zest.releaser, etc. Our setup.py is 2 lines long :wink:

I read this comment which made me doubt about what you'd think about this.

note: setup.cfg can read the __version__ attribute instead of parsing source files like it's done here

Let's discuss this in #683.

Support for this has been added to https://github.com/odwyersoftware/brunette :+1:

@richardARPANET maybe we should work on flake8 and other projects to support pyproject.toml?

@JulianVolodia just because the black maintainer is stubborn? Pass

sad... but true?
