Shell Templates

A local flake can be created like this:

nix flake init --template github:nomisreual/nomisshells#<name>

Note: <name> refers to the name of the template.

A note on Python

Overriding python packages can be achieved like this:

Instead of

python = pkgs.python311;

you can do something like:

python = pkgs.python311.override {
  packageOverrides = final: prev: {
    # Make django point to the django_5 package
    django = prev.django_5;
    # Disable tests for building django-extensions
    django-extensions = prev.django-extensions.overridePythonAttrs (old: rec {
      doCheck = false;
    });
  };
};

However, overriding packages can break other packages. Here, checks for django-extensions is disabled, as pointing django to django_5 makes them fail.

There is also a new shell with support for uv, named python_uv. It sets appropriate environmental variables to make sure uv picks up the provided python interpreter.
