catppuccin-alacritty-theme.nix

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

This repository and its flake are based on the great alexghr/alacritty-theme.nix.

Outputs

Each YAML file in the catppuccin/alacritty repo is exported as a package.

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

Apply a color scheme using home-manager

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

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

      modules = [

          nixpkgs.overlays = [ catppuccin-alacritty-theme.overlays.default ];

            programs.alacritty = {
              enable = true;
              # use a color scheme from the overlay
              settings.import = [ pkgs.catppuccin-alacritty-theme.catppuccin-mocha ];
            };
          };
        })
      ];
    };
  };
}

That's it 😄
