COSMIC

COSMIC is a desktop environment developed in the Rust programming language, using the iced cross platform GUI library for Rust, and Smithay as building blocks for its compositor, cosmic-comp. Cosmic-comp is comparable to smithay's own anvil compositor demonstration, just like the Wayland project uses Weston as demo compositor.

Installation

Currently packaged in nixpkgs master/unstable are below, one way to install them is to use a configuration file like this:

{ config, pkgs, ...}:

let
  unstable = import
    (builtins.fetchTarball https://github.com/nixos/nixpkgs/tarball/master)
    # reuse the current configuration
    { config = config.nixpkgs.config; };
in

{
  environment.systemPackages = with pkgs; [
    unstable.rustc
    unstable.just
    unstable.cosmic-icons
    unstable.cosmic-settings
  ];
}

You would add it to your main configuration.nix file in /etc/nixos/ like this:

   imports =
       [
           ./hardware-configuration.nix
           ./unstable.nix
       ];

then rebuild:

sudo nixos-rebuild switch
