Options & Overrides	5

You can override the package through the .override or .overrideAttrs mechanisms.
This is easily achievable on NixOS or Home Manager.

Package options

These are the default options that the Hyprland package is built with.
These can be changed by setting the appropriate option to true or false.

Package

(pkgs.hyprland.override { # or inputs.hyprland.packages.${pkgs.stdenv.hostPlatform.system}.hyprland
  enableXWayland = true;  # whether to enable XWayland
  withSystemd = true;     # whether to build with systemd support
})

NixOS & HM modules

{
  programs.hyprland = { # or wayland.windowManager.hyprland
    enable = true;
    xwayland.enable = true;
  };
}

Options descriptions

XWayland

XWayland is enabled by default in the Nix package.
You can disable it either in the package itself, or through the module options.

Using Nix repl

If you're using Nix (and not NixOS or Home Manager) and you want to override, you can do it like this:

$ nix repl
nix-repl> :lf github:hyprwm/Hyprland
nix-repl> :bl outputs.packages.x86_64-linux.hyprland.override { /* flag here */ }

Then you can run Hyprland from the built path.
You can also use overrideAttrs to override mkDerivation's arguments, such as cmakeBuildType:

$ nix repl
nix-repl> :lf github:hyprwm/Hyprland
nix-repl> :bl outputs.packages.x86_64-linux.hyprland.overrideAttrs (self: super: { cmakeBuildType = "Debug" })
