Poetry

CLI

• run poetry install with full dependencies
• https://python-poetry.org/docs/cli/

poetry install --with data

• only groups

poetry install --only data,jupyenv

• then poetry shell to enter the python virtualEnvironment

configFiles

Do not modify the top-level/pyproject.toml, which is generated by nix automaticlly. I would highly recommand the users to control the dependencies through poetry’s groups.

• add your custom poetry packages

  custom dir: ./nix/python/packages/

poetry add --group data -C ./nix/python/packages/

Notice Don’t forget run direnv reload to re-generate toplevel/pyorject.toml

• merge the pyproject.toml from other poetry’s projects

  Notice: make sure the pyproject.toml under the path vaule.

{
  poetry =
    l.recursiveUpdate (cell.lib.mergePoetryEnv [
      {
        path = ./packages;
      }
      {
        path = "${inputs.dataflow2nix}/nix/prefect/packages";
        overrides = false;
      }
      {path = "${inputs.desci}/nix/python/packages";}
    ]) {
      # add your overrides here
      #  pyproject = {
      #  tool.poetry.dependencies.polars = {
      #   version = "^0.15.1";
      #   format = "wheel";
      # };
      # };
    };
}
