Pyright git hook fails to use languages.python.uv virtual environment

[Ten0]

With the following configuration

  languages.python = {
    enable = true;
    directory = "./mypythonproject";
    version = "3.11.10";
    uv = {
      enable = true;
      sync.enable = true;
    };
  };

  packages = with pkgs; [
    pyright
  ];

  git-hooks.hooks.pyright = {
    enable = true;
    package = pkgs.pyright; # For consistency with packages above
    args = [ "--warnings" ]; # Make it fail if warnings are present
  };

pyright will not run in the virtual environment that uv created, leading to it not detecting packages that would otherwise be available, so it can't properly typecheck.

e.g.
with pyproject.toml

[project]
	dependencies = [
		"requests>=2.28.2",
	]
	description = "Add your description here"
	name = "myproject"
	readme = "README.md"
	requires-python = "==3.11.10"
	version = "0.0.0"

python code:

import requests

we get:

warning: Import "requests" could not be resolved from source (reportMissingModuleSource)
0 errors, 1 warning, 0 informations

Whoops, wrong place, this should probably have been opened at devenv.

Anyway, found a workaround:

let
  pyright_in_venv = (
    (pkgs.writeShellApplication {
      name = "pyright";
      runtimeInputs = [ pkgs.pyright ];
      text = ''
        cd ${
          lib.escapeShellArg (
            lib.strings.normalizePath (config.devenv.root + "/" + config.languages.python.directory)
          )
        }
        uv run pyright "$@"
      '';
    }).overrideAttrs
      (oldAttrs: {
        name = "pyright-in-venv";
      })
  );
in
{
  languages.python = {
    enable = true;
    directory = "./mypythonproject";
    version = "3.11.10"; # Same as in the appdaemon docker image and pyproject.toml
    uv = {
      enable = true;
      sync.enable = true;
    };
  };

  packages = [
    pyright_in_venv
  ];
