I am very excited about this change. Count with me for Python. Is there
a (draft) API to start coding against?
In Python, there's an effort to enable things like this generator, e.g.
[PEP 517].
Here, gathering BuildRequires is a two-step process:
- the "build backend" is specified in declarative metadata;
- then the build backend can query backend-specific metadata for
additional BuildRequires.
Is that possible with the current plans?
BTW: New versions of Python's usual build system (setuptools/setup.py)
will be forward compatible with PEP 517. Please do not write generators
that use setup.py directly.
We currently have no BuildRequires generators written yet, so we can
Do It Right(TM) for this. :)
That said, I'm not sure how we will be broadly compatible for divining
setup_requires if they are specified...
