Packagers: Can we use poetry build for package? Drop Python 2?

[tony]

Goal

Consolidate project dev utilities, e.g. virtualenv, package versioning/pinning, and build + publishing: poetry

• https://repology.org/project/tmuxp/versions
• https://pkgs.org/download/tmuxp

Question Will removing setup.py from source break compatibility?

poetry build link creates:

1. dist/packagename-<version>.tar.gz (similar to python setup.py sdist), and
2. A wheel python3 setup.py bdist_wheel --universal

What would still be available?

• .tar.gz package and wheel on PyPI
• ability to create sdist / wheel via poetry build (would require having poetry installed with a compatible version)
• https://github.com/mgorny/pyproject2setuppy - generate setup.py without requiring poetry

• FreeBSD - Confirmed via email Aug 17
• Slackpackages
• Arch

Poetry-only (remove setup.py in src)?

• Gentoo - Confirmed via email Aug 17
• Redhat / Fedora - Confirmed via email Aug 23 2020
• Debian / Ubuntu - Possibly an issue (email Aug 22 2020)
• FreeBSD - Confirmed via email Aug 17 - ok since it generates a setup.py file
