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.

## Demo



https://github.com/hroncok/pyprojectize/compare/originals..specfiles



## 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".
