# ZShell

A feature-rich desktop shell for Hyprland built with Quickshell and Qt6/QML. Provides a modern, Material Design 3 inspired status bar, application launcher, notification center, wallpaper manager with dynamic color theming, and lock screen.

Features

• Status Bar - Configurable top panel with workspace indicators, audio controls, system resource monitors (CPU/RAM/GPU), system tray, clock with calendar, and notification bell
• Application Launcher - Fuzzy search with app frequency tracking, special search prefixes for filtering by category, description, keywords, etc.
• Notification Center - Full notification daemon with grouped notifications, popups, persistent storage, and Do Not Disturb mode
• Wallpaper Manager - Browse and select wallpapers with live preview carousel
• Dynamic Color Theming - Automatic Material Design 3 color palette generation from wallpapers
• Lock Screen - Secure session lock with PAM authentication
• Hyprland Integration - Deep integration with Hyprland for workspaces, window focus, keyboard state, and more

Dependencies

• Qt 6.9+
• Quickshell
• Hyprland
• Python 3 with materialyoucolor and Pillow (for dynamic color generation)
• PipeWire (for audio)

Installation

cmake -B build -G Ninja
ninja -C build
sudo ninja -C build install

This installs the QML plugin to /usr/lib/qt6/qml.

NixOS

In your flake.nix file, add the following in your inputs.

inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    z-bar-qt = {
        url = "github:Zacharias-Brohn/z-bar-qt/";
        inputs.nixpkgs.follows = "nixpkgs";
    };
};

Below a full example of what it could look like.

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    z-bar-qt = {
        url = "github:Zacharias-Brohn/z-bar-qt/";
        inputs.nixpkgs.follows = "nixpgks";
    };
  };

  outputs =
    inputs@{
      nixpkgs,
      self,
      ...
    }:
    let
      system = "x86_64-linux";
      pkgs = import nixpkgs { inherit system; };
    in
    {
      nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
        specialArgs = {
          inherit inputs;
          inherit system;
        };
        modules = [
          ./configuration.nix
        ];
      };
    };
}

Now you can add z-bar-qt as a nixpkgs in environment.systemPackages (or optionally in your homePackages).

{ pkgs, inputs, ... }:

{
    environment.systemPackages = with pkgs; [
    inputs.z-bar-qt.packages.${system}.zshell
    ];
}

You can now run zshell to run the bar.
