alacritty-theme.nix

This repo packages all of the themes available at alacritty/alacritty-theme as individual flake outputs for easy use in your nix-managed Alacritty config.

❗❗❗ Since this PR the themes are exported as TOML files. They can only be consumed by Alacritty >= 0.13.0 (currently avilable in nixpkgs-unstable but not in nixos-23.11). If you're using Alacritty from a stable NixOS release then pin this commit 2cd654 to consume YAML formatted themes.

Outputs

Each TOML file in the alacritty-theme/themes folder is exported as a package.

Furthermore an overlay is provided that groups all of these themes under a single attribute set: pkgs.alacritty-theme.

Apply a color scheme using home-manager

This sample config applies the overlay and configures cyber_punk_neon as the color scheme for Alacritty using home-manager.

You can read more about installing overlays with Flakes on NixOS Wiki.

# flake.nix
{
  inputs.alacritty-theme.url = "github:alexghr/alacritty-theme.nix";
  outputs = { nixpkgs, alacritty-theme, ... }: {
    nixosConfigurations.yourComputer =  nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ({ config, pkgs, ...}: {
          # install the overlay
          nixpkgs.overlays = [ alacritty-theme.overlays.default ];
        })
        ({ config, pkgs, ... }: {
          home-manager.users.you = hm: {
            programs.alacritty = {
              enable = true;
              # use a color scheme from the overlay
              settings.import = [ pkgs.alacritty-theme.cyber_punk_neon ];
            };
          };
        })
      ];
    };
  };
}

That's it 😄

Binary Cache

I maintain a personal binary cache running Attic and push outputs to it. To use the cache add it and its public key to your configuration.nix:

# configuration.nix
{
  nix.settings = {
    extra-substituters = [
      "https://attic.alexghr.me/public"
    ];
    extra-trusted-public-keys = [
      "public:5MqPjBBGMCWbo8L8voeQl7HXc5oX+MXZ6BSURfMosIo="
    ];
    # only if your user is not trusted already
    extra-trusted-users = [
      "<your username>"
    ];
  };
}

Or to your nix.conf if you're not running NixOS:

# nix.conf
extra-substituters = https://attic.alexghr.me/public
extra-trusted-public-keys = public:5MqPjBBGMCWbo8L8voeQl7HXc5oX+MXZ6BSURfMosIo=
extra-trusted-users = <your username>
