What is the purpose of the empty setup.py?

[jhossbach]

As of the latest big merge, the setup.py is empty. I believe this to break some of the packaging repos, e.g. arch (https://archlinux.org/packages/community/any/python-rope/) as they try to install rope using python setup.py install --skip-build

The empty setup.py is currently needed for setuptools/pip to do an editable install. Once this is fixed in pip, then we might eventually be able to remove it and rely only on pyproject.toml but from my understanding this is still necessary.

I'm not quite sure what the problem is with arch build or why they are using --skip-build, as I don't manage the arch package.

I think @Foxboron is the Arch maintainer for the rope package in Arch, would you be able to provide some context here?

I got here after getting a ModuleNotFoundError. After digging the arch python package guidelines I found that python-pytoolconfig is not in the depends list in the PKGBUILD. Also, according to the guidelines the python setup.py install ... is used when the pyproject.toml does not exist or it fails to contain the [build-system] table, both of which are not true.
So my guess is that

• python-pytoolconfig has to be added to the depends list and
• the install method can be adapted to be PEP517 compliant

Just realized that a bug has already been reported.

I've been very lazy recently :)

[jhossbach]

Not a problem :) What about the second item though?

[Foxboron]

That's an issue for when a new rope release is made. The latest still works with setup.py.

Alright, thanks for the clearing up. 👍
