:/ I'm currently working in nix repl and could not find anything on how to enable traces there.

Are you talking about https://github.com/nim65s/matrix-webhook

I cloned it and built it just fine

my default.nix:

{ pkgs ? import <nixpkgs> {} }:
let
  poetry2nix_repo = fetchGit {
    url = "https://github.com/nix-community/poetry2nix.git";
    ref = "master";
    rev = "96e3794e5d4d48e7f85d0dfcee90256a3a65475b";
  };
  poetry2nix = import poetry2nix_repo {
    inherit pkgs;
    poetry = pkgs.poetry;
  };
  zulipEnv = poetry2nix.mkPoetryEnv {
    projectDir = ./.;
    preferWheels = true;
    python = pkgs.python310;
  };
in zulipEnv.env

Hi all! I'm working on a PR to fix this issue: https://github.com/nix-community/poetry2nix/issues/613. But I'm running into something I don't know how to solve. To address this ticket I need to adjust a SetupHook to format a TOML file. Since there don't seem to be standalone TOML formatters out there I am planning on using https://pypi.org/project/toml/ or https://github.com/sdispater/tomlkit. However, adding that library as a dependency to the SetupHook like so:

makeSetupHook
{
  name = "remove-path-dependencies.sh";
  deps = [ python.pythonForBuild.pkgs.toml ];
  substitutions = {
    inherit pythonInterpreter;
    pyprojectPatchScript = "${./pyproject-without-special-deps.py}";
    fields = [ "path" ];
    kind = "path";
  };
} ./remove-special-dependencies.sh

seems to result in nix-build getting stuck in a loop during instantiation of the derivations. I guess this has something to do with pythonForBuild and some bootstrapping stuff, but I'm unsure how to proceed. Does anyone have an idea?

Figured it out:

      dontRemoveSpecialDependencies = map (p: p.pname) (
        python.pythonForBuild.pkgs.requiredPythonModules (with python.pythonForBuild.pkgs; [
          tomlkit
          packaging
          poetry-core
        ]));
...
      nativeBuildInputs = [
        pythonPackages.poetry2nixFixupHook
      ]
      ++ lib.optional (!isSource && (getManyLinuxDeps fileInfo.name).str != null) autoPatchelfHook
      ++ lib.optionals (format == "pyproject" && ! lib.elem name dontRemoveSpecialDependencies) [
        pythonPackages.removePathDependenciesHook
        pythonPackages.removeGitDependenciesHook
      ];

  };

but this is a snippet of my pyproject.toml:

[tool.poetry.dependencies]
python = "^3.10"
mypy = "^0.940"

ok let me try without wheels
