Help packaging copilotchat-nvim

Hi All,

I’m trying to build a vim plugin that uses remote plugins that require some python packages.

Plugin: GitHub - CopilotC-Nvim/CopilotChat.nvim: Chat with GitHub Copilot in Neovim

{
  vimUtils,
  fetchFromGitHub,
  python3,
  buildEnv,
  lib,
  stdenv,
  makeWrapper,
  ...
}: let
  pname = "copilotchat-nvim";
  version = "1.3.0";
  src = fetchFromGitHub {
    owner = "CopilotC-Nvim";
    repo = "CopilotChat.nvim";
    rev = "v${version}";
    sha256 = "sha256-vbqtaRejGt+xXi1dfzclKL5/ZynEzBJfqXUHO+sC880=";
  };
  meta = {
    description = "Chat with GitHub Copilot in Neovim";
    homepage = "https://github.com/CopilotC-Nvim/CopilotChat.nvim/";
    license = lib.licenses.gpl3;
  };
  # Define the Python environment with the required packages
  pythonEnv = python3.withPackages (ps:
    with ps; [
      python-dotenv
      requests
      prompt-toolkit
      tiktoken
    ]);
  # Build the Vim plugin
  vimPlugin = vimUtils.buildVimPlugin {
    pname = "${pname}-lua";
    inherit src version meta;
    propagatedBuildInputs = [pythonEnv];
  };
in
  buildEnv {
    name = pname;
    paths = [vimPlugin pythonEnv];
    buildInputs = [pythonEnv];
  }

I found something online that I am using as a base. I can get it to run if I add the python packages to my Neovim config in home-manager. But ideally, I would like to have it neatly packaged and self-contained with this nix expression. How can I make the python packages available at run time to the package, and should I even be using buildEnv?

I am currently getting the following error, when I run :UpdateRemotePlugins

Clearly, the plugin does not see the installed python packages :thinking:.

However, if I do the following, it works with my NixVim setup this works.

{
  programs.nixvim = {
    extraPlugins = with pkgs; [

      copilotchat-nvim
    ];

    # For copilot-chat
    extraPython3Packages = p: [
      p.python-dotenv
      p.requests
      p.prompt-toolkit
      p.tiktoken
    ];
 };
}
