Many thanks for this, and the other replies from Bernat Gabor <gaborjber...@gmail.com> and Tzu-ping Chung <uranu...@gmail.com>. I had already come across PEP-517 actually, but hadn't appreciated its importance. I think i've managed to get my packaging to work using PEP-517 callbacks. I was a little surprised to find out that one can't use pip to create an sdist, but i'm a bit late to this party and it looks like there's been plenty of discussion about this in the past. I've ended up with a pyproject.toml that points to a setup.py file which functions both as a PEP-517 module (providing functions build_wheel() and (unused) build_sdist()), and also as a conventional setup.py script for things like './setup.py sdist'. I've come across a problem where an old pip-18.1 fails to install from an sdist or wheel, with error: ERROR: You must give at least one requirement to install (see "pip help install") pip-20.2.1 and pip-21.0.1 work fine, including installing from an sdist on test.py.pi. Should i be worried about this? I'd like my package to install on anyone's machine, regardless of their pip version. But maybe users are expected to always run a recent pip version? After all it's easy enough to upgrade it.
