setuptools 30.3.0 introduced declarative package config, allowing us to put most of the options we used to pass directly to setuptools.setup in setup.cfg files. For example, given following setup.cfg:
[metadata]
name = hello-world
description = Example of hello world
[options]
zip_safe = False
packages =
hello_world
install_requires =
examples
example1
A setup.py containing only
import setuptools
setuptools.setup()
will do all the right things.
However, I haven't been able to figure out the correct syntax for extras_require. In setup args, it is a dictionary, like
setup(extras_require={'test': ['faker', 'pytest']})
But I can't figure out the right syntax to use in setup.cfg. I tried reading the docs, but I can't find the correct syntax that setuptools expects for a dictionary there. I tried a few guesses, too
[options]
extras_require =
test=faker,pytest
it fails.

Reading the code, I'm not 100% sure this is supported, but based on PEP 508 it seems this should be a supported use case. What am I missing?
