If you want to try it out, you can run the following command:

nix run github:comavius/wayggle-bg -- default --name box

wayggle-bg is a wallpaper application for Wayland compositors that supports GLSL shaders, including ShaderToy and The Book of Shaders formats. It allows you to set animated wallpapers using custom shaders.

Demonstration video above.

wayggle-bg default --name box

In this mode, this application passes uniform variables in shader toy format, like iTime.

wayggle-bg shadertoy --fragment-shader <path-to-shadertoy-fragment.glsl>

In this mode, this application passes uniform variables in The Book of Shaders format, like u_time.

wayggle-bg book-of-shaders --fragment-shader <path-to-book-of-shaders-fragment.glsl>
# You can also specify a custom vertex shader
wayggle-bg book-of-shaders --fragment-shader <path-to-book-of-shaders-fragment.glsl> --vertex-shader <path-to-book-of-shaders-vertex.glsl>

Hyprland users can enable cursor support by passing --enable-cursor-support flag.

wayggle-bg is available through the Nix package manager and it's distributed as a Nix flake.

# flake.nix
{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    wayggle-bg = {
      url = "github:comavius/wayggle-bg";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, wayggle-bg }:
    let
      system = "x86_64-linux";
      pkgs = import nixpkgs {
        inherit system;
      };
    in
    {
      packages.default = wayggle-bg.packages.${system}.default;
    };
}

If you have nix installed but do not intend to configure flake.nix, you can simply nix run or nix build the package:

nix run github:comavius/wayggle-bg # for running once
nix build github:comavius/wayggle-bg # for building the app

If you don't have nix installed, prepare pkg-config, libglvnd, wayland and rust toolchain.
