Why not pull in the dependency generator I

Mageia is using an earlier variant of it now. It establishes common
names for Python packages that provide egg-info or dist-info data
(egg/wheel metadata installed on the system) that can be used for
standardizing how Python dependencies are referenced.
this is certainly very useful and we're looking into it, but it doesn't
seem to solve my question?
to restate, I need to configure BuildRequires (not install-time
requirements) and pull in, as automagically as possible, all rpm
packages of "python module foo" for all supported pythons (that is
python2 and python3 at the moment, pypy3 in the near future (hopefully))
Having the standardized names means you can just read requirements.txt
or whatever and generate the list and expect it to work. It's a step
that'd be required for that. OBS would likely need to grow the ability
to run something like pyp2rpm spec generator before starting the
build, which means being able to read requirements.txt or setup.py for
the deps and resolving them properly.
also, BuildRequires are evaluated by OBS before
rpmbuild starts, so I
can't rely on the usual ways of injecting macros into the build environment.
(i'd also be interested in what Fedora has to say about the single-spec
thing, . ISTM you don't do anything similar at the moment?
but i suppose that's for a different thread altogether)
As far as I know, openSUSE was the *only* distribution *not* doing
single spec Python 2/3 packaging. Fedora and Mageia both do.
Also, Fedora and Mageia (and other related distributions) have a
shared set of macros for Python packaging. Unfortunately, openSUSE
does not use these, so Python module packaging differs quite a bit
between openSUSE and the other RPM based distributions I work on.
