Hello folks, Tired of figuring out the right sed or patch to modify dependency constraints in your Python packages? Or having your carefully crafted regex break because upstream reformatted their metadata? %pyproject_patch_dependency is here to help.
A new macro has been merged into pyproject-rpm-macros and is available in Rawhide, F44 and F43 as a provisional feature. It provides a uniform way to override upstream dependency constraints in %prep, regardless of the build backend. It affects both BuildRequires and runtime Requires. Example usage: %prep %autosetup -p1 %pyproject_patch_dependency cython:drop_upper %pyproject_patch_dependency numpy:set_upper:3.0 %pyproject_patch_dependency legacy-dep:ignore It also handles circular/sibling dependencies in multi-wheel specs via the br_only suffix. A sibling package can be ignored in BuildRequires (since it's not yet installed during build) while keeping it as a runtime Requires: %pyproject_patch_dependency sibling-package:ignore:br_only The feature is marked provisional, meaning the API may change based on real-world usage. If you maintain Python packages and deal with dependency version overrides, I'd appreciate if you gave this a try and reported any issues.
