I am implementing requirements-in-setup.cfg for wheel because there is no place to put environment markers in setup.py
The Requires-Dist: lines in PKG-INFO use ; to separate environment markers from the dep name. Is setup.cfg supposed to use -- ? Why?
requires-dist = keyring; python_version == '2.6'
requires-dist = keyring -- python_version == '2.6'
(Sorry, meant to reply-all; hate how that's not a default on python.org mailing lists.)
Where does it say that? I see to recall it always using ; both in the PKG-INFO and in setup.cfg. I'm probably mistaken, but I'm just wondering where you got this from? And if so I wonder if it could be changed. The -- syntax is just confusing IMO.
Of course if you are always installing from wheel you would probably continue to specify anything build-related in Python, and only the install-time metadata from setup.cfg's [metadata] section would need environment markers. Wheel doesn't include setup.cfg or setup.py, just the .dist-info/METADATA generated from those files.
