Converts a Fedora RPM spec file from %py3_build etc. to %pyproject macros

pyprojectize

This helps you convert a Fedora RPM spec file from %py3_build etc. to %pyproject macros. This program only operates on the spec file itself, and hence has limited knowledge. The resulting spec file is not guaranteed to be buildable and manual verification and completion of the transition is strongly advised.

$ python pyprojectize.py --help
usage: pyprojectize [-h] [-l] [-i MODIFIER] [-x MODIFIER [MODIFIER ...] |
                    -o MODIFIER] [-s SOURCEDIR]
                    [SPECFILE]

positional arguments:
  SPECFILE              path to the spec file to convert

options:
  -h, --help            show this help message and exit
  -l, --list-modifiers  list all available modifiers and exit
  -i, --info MODIFIER   display documentation for given modifier
  -x, --exclude MODIFIER [MODIFIER ...]
                        exclude given modifier
  -o, --only MODIFIER   run only one given modifier
  -s, --sourcedir SOURCEDIR
                        path to the source directory, relevant for %include
                        etc. (default: spec's parent)

If you wish to process multiple specfiles at a time, run this tool via
parallel, etc. If you wish to inspect/commit result of each modififer
separatelly, you can loop over pyprojectize -l calling pyprojectize -o
$modifer each time.

Installation

This is a pip-installable package.

pip install pyprojectize

Or use uv, pipx etc.

Available modifiers

add_pyproject_buildrequires

If there is no %generate_buildrequires section, add it after %prep.

Insert %pyproject_buildrequires to the end of %generate_buildrequires.

remove_setuptools_br

Remove BuildRequires for setuptools, they should be generated.

py3_build_to_pyproject_wheel

In the %build section, replace %py3_build with %pyproject_wheel. Arguments (if any) are passed to -C--global-option. Environment variables (if any) are exported on the previous line.

py3_install_to_pyproject_install

In the %install section, replace %py3_install with %pyproject_install. Any arguments or environment variables are discarded. Installing a wheel does not need those.

egginfo_to_distinfo

In all the %files sections, replace .egg-info with .dist-info. The .dist-info filename is updated if possible (e.g. to use canonical name and version). Works reasonably well even with macronized filenames.

add_pyproject_files

If there is only one %files section with %{python3_sitelib} or %{python3_sitearch}, replace the manually listed files with %pyproject_save_files and -f %{pyproject_files}.

In case the %license files match patterns recognized by setuptools' defaults, uses %pyproject_save_files with -l and removes them.

add_pyproject_check_import

If %pyproject_save_files is used in %install and %pyproject_check_import is not used in %check, add %pyproject_check_import to the beginning of %check (create the section if needed).

update_extras_subpkg

Replace %python_extras_subpkg -i ... with %pyproject_extras_subpkg, preserve other arguments.

remove_python_provide

Remove %python_provide or replace it with %py_provides if the package name isn't the same.

If %py_provides is added, also remove the Provides: for the same name.

This does not detect packages without files yet. Packages without files need %py_provides even when the package name is the same.

remove_python_enable_dependency_generator

Remove %python_enable_dependency_generator, as the generator is enabled by default.

remove_pyp2rpm_comment

Remove the # Created by pyp2rpm-X.Y.Z comment. The spec file is changed enough for this to no longer matter.

remove_remove_bundled_egginfo

Remove the # Remove bundled egg-info comment and the followup rm ...egg-info. There is no such thing as "bundled egg-info".
