pyproject RPM macros

This is a provisional implementation of pyproject RPM macros for Fedora 30+.

These macros are useful for packaging Python projects that use the PEP 517 pyproject.toml file, which specifies the package's build dependencies (including the build system, such as setuptools, flit or poetry).

Usage

If your upstream sources include pyproject.toml and you want to use these macros, BuildRequire them:

BuildRequires: pyproject-rpm-macros

This will bring in python3-devel, so you don't need to require python3-devel explicitly.

Then, build a wheel in %build:

%build
%pyproject_wheel

And install the wheel in %install:

%install
%pyproject_install

Limitations

%pyproject_install currently installs all wheels in %_builddir. We are working on a more explicit solution.

This macro changes shebang lines of every Python script in %{buildroot}%{_bindir} to #! %{__python3} %{py3_shbang_opt} (#! /usr/bin/python -s). We plan to preserve exisiting Python flags in shebangs, but the work is not yet finished.

Currently, the macros do not automatically generate BuildRequires. We are working on that as well.
