Would this create ovrrides for all depedencies in the poetry.lock? What do you think about a way to tell poetry2nix to not create overrides for particular packages, when I know python3Packages.particular-package would work for my project, requires less build time on my end, and is well maintained. Or does that lead problems

Excerpt:

# Create a Python overlay from pdm.lock filtered by what already exists in nixpkgs.
# This means that our overlay strictly extending nixpkgs for maximal binary cache hits.
let
  inherit (lib) flip elem attrNames filterAttrs;

  project = pyproject-nix.lib.project.loadPDMPyproject {
    projectRoot = ./.;
  };

  overlay' =
    lib.composeManyExtensions [
      (pdm2nix.lib.lock.mkOverlay {
        inherit project;
        preferWheels = true;
      })
    ];

in pyfinal: pyprev: let
  attrExists = flip elem (attrNames pyprev);
  applied = overlay' pyfinal pyprev;
in
  filterAttrs (n: _: ! attrExists n) applied // {
    # Nixpkgs has an ancient & broken version
    inherit (applied) ezdxf;
  }

actually seems like it's env -> pynacl -> sphinx-hook... gotta dig more into it

In reply to @silvio:booq.org
Apparrently I'm not the first one having problems with ansible -> pynacl -> sphinx, but I have no clue how to fix it right now.

this seems to be it:

  overrides = poetry2nix.overrides.withDefaults (final: prev: let
    rm.lists = lists: old: builtins.mapAttrs (name: value: lib.subtractLists value old."${name}") lists;
    modified = pkg: fns: pkg.overridePythonAttrs (oldAttrs: lib.pipe oldAttrs (builtins.map (fn: entry: entry // (fn entry)) fns));
  in
    builtins.mapAttrs (name: modified prev."${name}") {
      pynacl = [
        (rm.lists {nativeBuildInputs = with final; [sphinxHook];})
        (rm.lists {outputs = ["doc"];})
      ];
      pyjwt = [
        (rm.lists {nativeBuildInputs = with final; [sphinxHook sphinx-rtd-theme];})
        (rm.lists {outputs = ["doc"];})
      ];
    });

        (rm.lists {outputs = ["doc"];})
      ];
    });

basically I'm dropping doc output and a single nativeBuildInputs entry from both pyjwt and pynacl packages

{pkgs}:
let
  poetry2nix = import (
    builtins.fetchTarball {
      name = "poetry2nix-2024.8.2346599";
      url = "https://github.com/nix-community/poetry2nix/archive/7619e43c2b48c29e24b88a415256f09df96ec276.tar.gz";
      sha256 = "10nf9213h7vkzrqhrgk88r5sd2rq19cvdpnn59f65ifak790sgc0";
    }
  ) {
    inherit pkgs;
  };
in
  poetry2nix.overrideScope (finalPoetry2nix: prevPoetry2nix: {
    defaultPoetryOverrides = prevPoetry2nix.defaultPoetryOverrides.extend (final: prev: {
      gdal = prev.gdal.overridePythonAttrs (oldAttrs: {
        nativeBuildInputs = (oldAttrs.nativeBuildInputs or []) ++ [final.numpy];
      });
    });
  })

results in "error: value is null while a set was expected"
