Created a nix flake of t3code

@t3dotgg

As a Nixos user, I wanted this lovely application to work nicely on my system. It was important to me to be able to make it declarative. Hence, I created a flake to make this possible. I'm still ironing things out but I was able to install the desktop version (AppImage) on my system and make it discoverable with launchers. I'm still working on the t3 (local browser) version and I want be able to provide it on arm as well for darwin-nix users.

Here is the link: https://github.com/Sawrz/t3code-nix

@t3dotgg @juliusmarminge If you want to provide the flake by yourself and maintain it, I don't mind and would transfer the repo to you guys. The only thing I care, is to use this lovely application on my system =)

Thank you for making t3code open-source and allowing other developers increasing their productivity. Today is like christmas and I'm five again!

I mashed this together and have been using it without issue for about a month. I never noticed there should be a desktop version as I only really care for web-based apps for remote hosting :)

Original snippet

clone repo and add the flake there,

    {
      packages = forAllSystems (
        system:
        let
          pkgs = import nixpkgs { inherit system; };
        in
        {
          t3code = mkT3code pkgs;
        }
      );
    };
}

I then made an alternative flake, just to experiment which I try to add options to enable more binaries like gitlab, jujutsu etc. using options:
https://github.com/jakob1379/t3code-flake

t3code.override {
    enableClaude = true;
    enableJujutsu = true;
    enableAzureDevOps = true;
  }

bump to 0.23: flake.nix

slight changes required due to updated project structure...:
