Add Nix flake

[emanueljg]

This PR adds support for the Nix build system.

There is already a NixOS package for discordo: https://search.nixos.org/packages?query=discordo

[Arian-D]

Hey, are there any updates on this?

I was the one who originally packaged discordo for nixpkgs earlier this year, and while I think it makes it more accessible for most people, I think a flake would provide additional benefits.

My biggest gripe at the moment is that I'm either using a version from last month, or if I want to get the most recent changes I'd have to pull and go build . manually. With nix flakes this would be a simple

nix run github:ayn2op/discordo/main

Nix would then run discordo, and if the most recent version is not there, it would pull and rebuild it before running.

[linuxmobile]

Hi, Does anyone know why the flake was removed?

[epetousis]

@ayn2op not required obviously but it would be pretty sweet if this could be merged (pending the changes to actually make it work). I understand if you're not interested in extra maintenance burden, however.

You can obviously just do doCheck = false temporarily but I would rather that the check goes through.

Fixed in the latest commit.

[ghost]

oh right, the new changes. [::i]text[::I] is better because [::-] resets all the attributes instead of resetting only the italic attributes.
[::b]BOLD[::i]italic[::-]not BOLD or italic[::-]
[::b]BOLD[::i]italic[::I]BOLD and not italic[::B]

I am using my own flake:
https://github.com/linuxmobile/kaku/blob/main/pkgs/discordo/default.nix

[emanueljg]

I've improved the flake further and now finally consider it ready for review.

• Taking inspiration from @linuxmobile's flake, a meta attribute has been added and the derivation should now support clipboard actions. I've taken the liberty of adding customizable drv flags for this, should you want a smaller tty-only closure.
• home-manager support has been added through a homeManagerModule. Here's how I use it in my own flake:

{ config, lib, discordo, ... }: {

  imports = [ discordo.homeManagerModules.default ];

  programs.discordo = {
    enable = true;
    settings = {
      timestamps = true;
      theme.messages_text.author_color = "red";
    };
    tokenCommand =
      let
        passBin = lib.getExe config.programs.password-store.package;
        token = "discord-token";
      in
      "${passBin} ${token}";
  };
}  

Note that installation is still possible without home-manager. Just as before, it's as simple as

{ discordo, pkgs, ... }: {

  environment.systemPackages = [
    discordo.packages.${pkgs.system}.default
  ];
}

though of course you'll lose out on the dotfile management that home-manager is used for.

Please check ./nix/hm-module.nix for implementation details and option reference.
When this PR is merged, we can create a follow-up PR that documents the Nix-related stuff.
