Removed setup.py.

[KOLANICH]

It turned out that only setup.cfg is enough for modern setuptools.

[henryiii]

Yeah, but then you can't do editable installs for development 👎 , and you lose GitHub's dependency graph for Python projects, since it doesn't trigger as a Python project (as of about a year ago, maybe they've fixed that now).

[henryiii]

The first problem will be fixed in the next Pip release: pypa/pip#9547 :) So I'd be more-or-less fine with it once there's a new pip. It does mean Python 2 and 3.5 development will be harder, but a) I don't do Python 2 development, I just fix CI issues when it fails, and b) these versions of Python will be dropped in the version after the "split-up" next version.

[henryiii]

The dependency graph is broken currently anyway, so losing setup.py won't be a big deal for that.

[henryiii]

Pip 21.1 is out. Will take a little while to show up in CI, and it will never support 2.7 and 3.5, so will likely wait till the next Plumbum version is out before merging. We need the editable mode for computing coverage, IIRC.

Are you aware of Remove support for setup.cfg only projects change in pip?

[henryiii]

That's poorly named. That only removes support for projects that have a setup.cfg but not a pyproject.toml, which was accidentally added in 21.1.2. We have a pyproject.toml.

And, yes, I was the one who caught the problem in 21.1.2 and asked for that PR, if you follow through the various discussions. :)

[henryiii]

I'm going to be very tempted to move to PyPA/flit with PEP 621 configuration instead of just deleting setup.py once we drop 2.7 & 3.5 support. The only thing we'd loose is the automatic versioning, which is admittedly a bummer. Thoughts? (By the time we do it, the PR to add PEP 621 to setuptools might be ready, but flit is still 10 faster...)

[KOLANICH]

The only thing we'd loose is the automatic versioning, which is admittedly a bummer.

If I remember right, poetry_core is capable to call setuptools plugins like setuptools_scm (and setuptools and poetry_core always call them, and the plugins check pyproject.toml for their configs themselves). Though I don't approve poetry tool itself (for it being adept of a cargo cult of virtualenvs and using them), poetry_core doesn't follow this approach (venvs are not mandatory) and so works pretty fine.

Coverage remained the same at 83.599% when pulling 23e4dca on KOLANICH-libs:remove_setup.py into 96e996a on tomerfiliba:master.

[henryiii]

I think PyPA/Hatch's hatchling is the right direction for Plumbum to rid itself of setup.py, FYI.

[henryiii]

FYI, after a little bit (to make sure there aren't regressions in 1.8.0), I'll drop 3.6 then merge the hatchling PR, which will remove setup.py. :)

[KOLANICH]

OK.
