Droidnix is a modular, declarative NixOS + Home Manager configuration system. It allows users to choose between Hyprland and Mangowc as their window manager, with shared and WM-specific configurations managed via Emacs Org and Nix Flakes. The project is designed for reproducibility, maintainability, and cross-machine compatibility.

Installed components:

Core

Hyprland

Mangowc

Goals, project Structure, import hierarchy

This project uses a modular NixOS configuration with Hyprland and MangoWC support, designed for literate programming and cross-device reusability. The Droidnix repository is organized into two main parts:

.assets/: Static, non-generated files (e.g., configs, scripts, themes).
Generated folders (common, hyprland, mangowc): NixOS and Home Manager configurations, generated from Org files.

Root Level

flake.nix is the entry point and imports:
- generated/system/
- generated/hyprland/
- generated/mangowc/
- Machine-specific configurations from assets/machines/

Generated Structure

The generated/ directory contains all generated configurations, divided into three main groups: system, hyprland, and mangowc.

System (`generated/system/`)

This directory contains system-wide configurations that are independent of the window manager.

Applications (`applications/`)

file_management/: Configurations for file managers and storage solutions.
gaming/: Settings for gaming-related software.
office_productivity/: Configurations for office software.
media_playback_editing/: Settings for media playback and editing software.
terminal_shell/: Configurations for terminal emulators and shells.

Development (`development/`)

databases/: Settings for local databases.
devops_ci_cd/: Configurations for DevOps tools.
programming_languages/: Settings for programming languages and their runtimes.
virtualization/: Configurations for virtualization and containerization tools.
web_development/: Settings for web development.

System Management (`system_management/`)

backups/: Settings for backup software.
bluetooth/: Configurations for Bluetooth devices and services.
power_management/: Settings for power management.
audio/: Configurations for audio.
hardware_sensors/: Settings for hardware monitoring.
logging_monitoring/: Configurations for system logging and monitoring.
login_manager/: Settings for the login manager.
monitor_setup/: Configurations for display settings.
networking/: Settings for networking.
printers_scanners/: Configurations for printers and scanners.
disk_management/: Settings for disk management.
security/: Security-related configurations.
system_updates/: Settings for system updates and package management.

Hyprland (`generated/hyprland/`)

This directory contains configurations specific to Hyprland.

animations_effects/: Settings for window animations and visual effects.
decorations/: Configurations for window decorations.
keyboard_binds/: Keyboard shortcuts for Hyprland.
notifications/: Settings for notifications.
statusbar_tray/: Configurations for the status bar and system tray.
task_launcher/: Settings for task launchers.
task_window_workspace_switcher/: Configurations for switching between windows and workspaces.
window_rules/: Rules for window behavior.

MangoWC (`generated/mangowc/`)

This directory contains configurations specific to MangoWC.

animations_effects/: Settings for animations and effects in MangoWC.
decorations/: Configurations for window decorations.
keyboard_binds/: Keyboard shortcuts for MangoWC.
notifications/: Settings for notifications.
statusbar_tray/: Configurations for the status bar and system tray.
task_launcher/: Settings for task launchers.
task_window_workspace_switcher/: Configurations for switching between windows and workspaces.
window_rules/: Rules for window behavior.

File Structure and Imports

Every top.nix file imports all .nix files in its directory.
Machine-specific configurations are stored in assets/machines/.
Themes and overrides are modular and reusable across setups.

Design Principles

Modularity: Each component is self-contained and reusable.
Consistency: Every directory follows the same import pattern.
Scalability: Easy to add new machines or configurations.

First Setup

Clone this repository.
Run the setup script: ./setup_droidnix.sh.
Edit .assets/common/conf/base.conf to choose your window manager (wm = "hyprland" or wm = "mangowc").
Tangle this Org file to generate Nix configurations: C-c C-v t in Emacs or use this: emacs README.org --batch -f org-babel-tangle && emacs --batch --eval "(setq org-html-htmlize-output-type nil)" README.org -f org-html-export-to-html
Build and switch: sudo nixos-rebuild switch --flake .#<hostname>.

The Assets Folder assets

The .assets/ folder contains all static files, such as configs, scripts, and themes. These files are not generated and can be edited directly.

`.assets/common/`

This folder contains files shared across both window managers, such as wallpapers, shell configs, and common scripts.

conf/base.conf: Defines the window manager choice and other global settings.
scripts/: System-wide scripts (e.g., utilities, helpers).

`.assets/hyprland/`

Hyprland-specific assets, including configs, themes, and scripts.

conf/: Hyprland configuration files (e.g., hyprland.conf).
themes/: Hyprland-specific theme scripts.
scripts/: Hyprland-specific scripts.

`.assets/mangowc/`

Mangowc-specific assets, including configs, themes, and scripts.

conf/: Mangowc configuration files.
themes/: Mangowc-specific theme scripts.
scripts/: Mangowc-specific scripts.

`.assets/machines/`

Machine-specific NixOS configurations (e.g., configuration.nix for maindroid and traveldroid).

The Actual Code code

This section contains the Org blocks for tangling Nix code into the generated folders.

`flake.nix`

The Nix flake definition for Droidnix.

{
  description = "Droidnix: A dendritic NixOS + Home Manager configuration";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    emacs-overlay = {
      url = "github:nix-community/emacs-overlay";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    catppuccin = {
      url = "github:catppuccin/nix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    zen-browser = {
      url = "github:youwen5/zen-browser-flake";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    hyprland.url = "github:hyprwm/Hyprland";
  };

  outputs =
    inputs@{
      nixpkgs,
      home-manager,
      emacs-overlay,
      catppuccin,
      zen-browser,
      hyprland,
      ...
    }:
    let
      lib = nixpkgs.lib;
      system = "x86_64-linux"; # Define the system explicitly
      user = import ./assets/flake/users/henrov.nix;
      machines = [
        "traveldroid"
        "maindroid"
      ];
    in
    {
      nixosConfigurations = lib.genAttrs machines (
        machine:
        lib.nixosSystem {
          inherit system;
          modules = [
            # Import machine-specific configurations
            ./assets/flake/machines/${machine}/top.nix

            # Home Manager and theme modules
            home-manager.nixosModules.home-manager
            {
              home-manager.useGlobalPkgs = true;
              home-manager.useUserPackages = true;
              home-manager.extraSpecialArgs = { inherit user inputs; };
            }
            inputs.catppuccin.nixosModules.catppuccin
          ];
          specialArgs = { inherit user inputs; };
        }
      );

      devShells.${system}.default = import ./assets/flake/terminal_shell/devshell.nix {
        inherit (nixpkgs) mkShell;
      };
    };
}

First the nix-files that flake really needs and that do not fit wel in the hierarchical structure

`assets/flake/users/henrov.nix`

This is the default user, just search and replace henrov another name if you want to change

{
  username = "henrov";
  hashedPassword = "$6$ISAmsPLyFi7idYXr$VmZsq.zMsyh1irSkyDNqtorNXG0oEHbbMVqTii1t8bymvrQ5ZQmbdi4OiBNeNYe/huHGrojXM.3TST2fTLz0T.";
  homeDirectory = "/home/henrov";
  stateVersion = "25.11";
  locale = "nl_NL.UTF-8";
}

`assets/flake/terminal_shell/devshell.nix`

This code defines a Nix shell environment (also called a "devShell") that you can enter using the nix develop command. When you enter this shell, Nix will provide the tools and dependencies listed in buildInputs.

{ mkShell }:
mkShell {
  buildInputs = with import <nixpkgs> {}; [
    nil
    nixfmt-rfc-style
  ];
}

`assets/flake/machines/traveldroid/top.nix`

This code defines the machine to build. Just search and replace traveldroid to provision another machine.

{ config, pkgs, lib, user, inputs, ... }:

{
  imports = [
    ./boot.nix
    ./hardware-configuration.nix
  ];

  options = {
    wm = lib.mkOption {
      type = lib.types.str;
      default = "hyprland";
      description = "Type of window manager to use";
    };
  };

  config = {
    # Minimal settings that must be defined here
    networking.hostName = "traveldroid";
    wm.type = "hyprland";

    # User configuration
    users.users.${user.username} = {
      isNormalUser = true;
      extraGroups = [ "wheel" "networkmanager" ];
      hashedPassword = user.hashedPassword;
      home = user.homeDirectory;
    };

    # Optional: Enable auto-login for testing
    services.getty.autologinUser = user.username;
  };
}

`assets/flake/machines/traveldroid/boot.nix`

This file has most of the settings the control how the computer boots up.

{ pkgs, ... } :
{
  boot = {
  initrd = {
  verbose = false;   # its a lot of logs. dont need it, unless we do.
  kernelModules = [ ]; # no kernel modules on boot
  };

  extraModulePackages = [ ];       # no extra packages on boot either
  kernelPackages = pkgs.linuxPackages_latest;  # latest greatest linux kernel
  kernelParams = [ "silent" ];       # quiet those logs

  consoleLogLevel = 0;         # quiten more logs
  plymouth.enable = true;        # graphical boot animation instead

  supportedFilesystems = [ "ntfs" ];     # should see the ntfs (windows)

  loader = {
  systemd-boot.enable = true;      # systemd-boot
  systemd-boot.configurationLimit = 10;
  efi.canTouchEfiVariables = true;     # allow editing efi to edit the boot loader
  timeout = 5;           # grub timeout to make a selection
  };
  };
}

Now we reach the top of the hierarchy which will call all other imports

`generated/top.nix`

The ./generated/top.nix file acts as an anchor or entry point for the entire chain of imports in the pyramid structure.

{ config, pkgs, lib, user, inputs, ... }:
{
  imports = [
    # First the stuff that we always want, regardless of windowmanager
    ./system/top.nix
        # Import window manager configurations based on the type defined in the machine file
    (if config.wm.type == "hyprland" then
      ./window_managers/hyprland/top.nix
    else if config.wm.type == "mangowc" then
      ./window_managers/mangowc/top.nix
    else
      assert false; "Unknown window manager type: ${config.wm.type}"
    )
  ];
}
