T3 Code Nightly Flake

Installs the Linux x86_64 T3 Code nightly as an AppImage and updates it from upstream GitHub releases. The AppImage is stored outside /nix/store at $XDG_DATA_HOME/t3code-nightly (or ~/.local/share/t3code-nightly) because Nix store paths are immutable.

Every update is SHA-256 verified against the digest published in the GitHub release. The Home Manager module runs a user timer every three hours, matching T3 Code's nightly release cadence. Launching t3code also checks for updates. Only nightly-tagged releases with a Linux x86_64 AppImage are selected; preview releases are skipped.

Home Manager

Add this flake as an input and import its Home Manager module:

{
  inputs.t3code-nightly = {
    url = "github:OpenStaticFish/t3code-desktop-flake";
    inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = { home-manager, t3code-nightly, ... }: {
    homeConfigurations.your-user = home-manager.lib.homeManagerConfiguration {
      # ...
      modules = [
        t3code-nightly.homeManagerModules.default
        {
          programs.t3code-nightly.enable = true;
        }
      ];
    };
  };
}

To check more or less often, set a systemd duration:

programs.t3code-nightly.updateInterval = "1h";

Set programs.t3code-nightly.autoUpdate = false to keep launch-time update checks while disabling the background timer.

Direct Use

nix run github:OpenStaticFish/t3code-desktop-flake

The package supports x86_64-linux, the only Linux architecture for which T3 Code currently publishes a nightly AppImage.
