I finally spent some time figuring out a minimal way of developing and packaging a Python library using a pyproject.toml file
It turns out you can do it with just a pyproject.toml file - no setup.py, no setup.cfg - and the only tools you need are pip and build, with no need to use Poetry/Hatch/Flit/etc for the simplest case
This is my first attempt at packaging without setup.py so I'm nervous I may have missed some important details or got things wrong - eager to hear feedback on this from Python packaging experts
In particular I'm not at all confident I understand how pip and build automatically discover Python modules and packages - a note on my confusion about that here: https://til.simonwillison.net/python/pyproject#user-content-it-finds-the-python-files-for-you
OK, I'm getting pretty comfortable with this pattern now - I just shipped pocket-to-sqlite 0.2.3 to PyPI, my first package to work using just a pyproject.toml file with no setup.py https://github.com/dogsheep/pocket-to-sqlite/tree/0.2.3
