In the past, when we were using poetry2nix, we used additional overlays in nix to ensure that nix flake overrides, e.g.
nix build --override-input kevm/k-framework v1.0.0, do not only override the nix flake but also the python package that was locked inpoetry.lock.With the migration to
uv2nix, this overlay was removed, causing confusion and overhead when wanting to override python code using nix flake overrides. This PR re-introduces these overlays that can be used in dependent nix flakes to re-establish this behaviour. Due touv2nixusing the newer nix python packaging toolingpyproject-nix, this code adds more complexity in comparison topoetry2nix, though it nonetheless achieves the same result.There will be similar PRs in other repositories introducing and using these pyproject-nix overlays.
