readthedocs seems to lack support for modern builds

[RonnyPfannschmidt]

fixed the issues, will need to add some docs later today

[RonnyPfannschmidt]

@pytest-dev/core this also serves as first example for going away from setuptools, please have a look

[RonnyPfannschmidt]

will squash locally after approval

[RonnyPfannschmidt]

Will reorder the commit content today to split the meaning

[RonnyPfannschmidt]

@nicoddemus i'd appreciat another look over before merging the split commits

[nicoddemus]

Great job!

I tried it now, the tool seems to work as expected.

I think we should also update the deploy workflow to use hatch, after all its main purpose is to do the build (and maybe publish) no?

[bluetech]

I think can use ' here to avoid the escaping

Suggested change

	"importlib-metadata>=0.12;python_version<\"3.8\"",
	'importlib-metadata>=0.12;python_version<"3.8"',

[nicoddemus]

@bluetech good catch, I think you mean these places?

pluggy/.github/workflows/main.yml

Line 145 in 70fde45

pip install --upgrade wheel setuptools setuptools_scm

pluggy/.github/workflows/main.yml

Line 112 in 70fde45

python -m pip install --upgrade pip setuptools

pluggy/.github/workflows/main.yml

Line 148 in 70fde45

run: python setup.py sdist bdist_wheel

[bluetech]

Yes exactly. I'm not sure if we want to keep using the pypa/gh-action-pypi-publish action or switch to using hatch publish, I'll leave it to @RonnyPfannschmidt to decide.

[KOLANICH]

There is an issue: hatchling itself depends on pluggy.

[ssbarnea]

I am against this as I prefer setuptools-scm, but I will not block the change.

[RonnyPfannschmidt]

Hatch VCS uses Setuptools-scm

[RonnyPfannschmidt]

This is currently indefinitely blocked as the dependency loop with hatchling needs a resolution

[KOLANICH]

Do I understand right that only migration to hatchling is blocked, but the rest of changes ("move importlib hacks to own module for typing") are not blocked.
