Hey y'all!

I'm working on nixifying a Python application, and chose to use poetry2nix due to previous familiarity.
Originally the project used hatch (not really relevant).

However, the end-result is a docker image (no surprises there).
And the docker image previously produces has much smaller size than the one generated by Nix.
(I'm leveraging nixpkgs's dockerTools.buildImage on the mkPoetryApplication).

We're talking like 125MiB vs 527MiB.

Probably optional dependencies somewhere

I feel like I'm probably missing something obvious, but I'm curious about what the easiest way to support a dependency that is not in nixpkgs or pypi is. Should I just use the built in nixpkgs tooling to define a nix build for that package and then add an override

Hi all,

I'm trying to build scikit-learn 1.5.0, and their changelog says they've switched to meson: https://scikit-learn.org/stable/whats_new/v1.5.html#version-1-5-0. When I add meson-python to nativeBuildInputs, metadata generation fails when running this file: https://github.com/scikit-learn/scikit-learn/blob/5491dc695dbe2c9bec3452be5f3c409706ff7ee7/sklearn/_build_utils/version.py

This seems like an opportunity to learn more about poetry2nix and submit a PR. Are there any good resources people can recommend on translating a meson build to a poetry2nix override?

Thanks!

I'm trying to patch the cython version used by a package:

peewee = super.peewee.overridePythonAttrs (old: let
            old_buildInputs = old.buildInputs or [];
            old_cython_filter = input: (builtins.substring 0 7 input.name) != "cython-";
          in {
            buildInputs =
              (builtins.filter old_cython_filter old_buildInputs);
              ++ [super.cython_0];
          });

But all I get is " error: value is a list while a set was expected" ...

Can anybody spot what I'm doing wrong?
