Python in Emacs through LSP

Python is a high-level interpreted Programming Language with some good functional constructs and a whitespace-sensitive syntax dynamic types objects and classes. It's a good Tool for data processing it's a good tool for building small utilities particularly with libraries like Click

emacs-lisp:tangle ~/nix/lisp/python.el

(provide 'cce/python)

In the CCE Python programming is done using pyright in the LSP.

nix:tangle ~/nix/hm/python.nix

{ pkgs, lib, ... }:

{
  home.packages = [
    pkgs.pyright
  ];
}

And I need to pull in poetry2nix in to my system using an overlay because the nixpkgs folks don't think it should be vendored. It's pulled in as a flake input pinned by the Arroyo System Flake's flake.lock.

nix:tangle ~/nix/snippets/poetry2nix-input.nix:mkdirp yes

poetry2nix = {
  url = "github:nix-community/poetry2nix";
  inputs.nixpkgs.follows = "nixpkgs";
};

nix:tangle ~/nix/nixos/poetry2nix.nix

{ inputs, ... }:

{
  nixpkgs.overlays = [
    (import "${inputs.poetry2nix}/overlay.nix")
  ];
}
