overlays

`lib.overlays.mkOverlay`

Generate an overlay to use with pyproject.nix’s build infrastructure.

See https://pyproject-nix.github.io/pyproject.nix/lib/build.html

sourcePreference: Whether to prefer sources from either: - wheel - sdist See FAQ for more information.
environ: PEP-508 environment customisations. Example: { platform_release = “5.10.65”; }
spec: Dependency specification used for conflict resolution. By default mkPyprojectOverlay resolves the entire workspace, but that will not work for resolutions with conflicts.
localProjects: Local projects loaded from lock1.loadLocalPackages
config: Workspace config
workspaceRoot: Workspace root
lock: Lock parsed by lock1.parseLock
pythonVersion: Override the Python version used for the requires-python assertion, dependency resolution & PEP-508 marker evaluation. Useful when the interpreter’s patch version (e.g. pkgs.python3X) doesn’t match the version constraint declared in requires-python.
