Recommended starting point.
nix flake init -t github:caniko/harbor-py
harbor-py
Reusable Python uv2nix and pyproject-nix infrastructure for Nix flakes.
Downstream flakes keep project policy local while sharing the boring Python/Nix plumbing.
uv environments
`mkUvVirtualEnv` and `mkUvCheckEnv` return immutable uv2nix environments. Use `${env}/bin/python`.
Dev shells
`mkUvDevShell` extraPackages are Nix tools only. Python deps stay in pyproject.toml and uv.lock.
Overrides
Setuptools, Torch runtime, and TorchCodec FFmpeg helpers live under `pythonOverrides`.
Template
`nix flake init -t github:caniko/harbor-py` scaffolds a consumer.
