Bernardo Magri e66537523a feat(installer): UX polish — dry-run, resume, UEFI gate, pre-flight, zram
Adds command-line flags and safety rails on top of the existing install.sh.

CLI:
- `--dry-run` generates the flake into /tmp/nomarchy-dryrun.* and parse-checks
  every produced file without touching the disk. Skips LUKS / user password
  prompts and the destructive confirmation; sets safe stub values.
- `--resume` reloads non-secret answers from /tmp/nomarchy-install.state.sh
  (saved via `declare -p` after each step) and skips already-answered prompts.
  Passwords are NEVER persisted — the user re-enters them.
- `--help` documents the flags.

Safety:
- Bail early in check_environment if /sys/firmware/efi is absent. The disko
  config assumes UEFI + ESP; on a BIOS-booted host we'd partially install
  before failing.
- After nixos-install, run `nixos-rebuild dry-build --flake /etc/nixos#$HOSTNAME`
  inside `nixos-enter` to surface evaluation errors while the live ISO is
  still around to fix them.
- ENABLE_IMPERMANENCE now defaults to "" so the resume path can distinguish
  "not yet asked" from a deliberate "false" answer.

Generated config:
- system.nix gets `zramSwap.enable = true;` — near-free memory headroom on
  small machines, harmless on big ones (kernel only uses it under pressure).

👑 Nomarchy

Nomarchy is a professional-grade NixOS distribution that replicates the Omarchy Wayland workflow with a strictly declarative, flake-based architecture. It provides a highly polished, "it just works" experience for power users who want a beautiful Hyprland environment without sacrificing the reliability of NixOS.

Key Features

  • Purely Declarative: Your entire desktop—themes, fonts, wallpapers, and toolchains—is defined in code.
  • Modular Merging Architecture: Distro code and user code are strictly separated. You can update the distro core without ever touching or breaking your personal configurations.
  • Interactive "Smart" Installer: Detects hardware, sets up networking, localizes timezones/keymaps, and offers multi-select software profiles.
  • Erase Your Darlings (Optional): Optional BTRFS root-wipe on boot ensures your system stays pristine and 100% declarative.
  • Dynamic Theming Engine: 20+ built-in themes with instant UI feedback via IPC (swww, waybar, and stylix).
  • Portable State (nomarchy-sync): Easily backup and sync your declarative config and dynamic state (theme/wallpaper choices) to a private Git repo.

📂 Component-Based Architecture

Nomarchy uses a Feature-Centric Directory Structure. For a comprehensive breakdown of the system architecture, folder roles, and module logic, see the Detailed Architecture Documentation.

Configuration, modules, and utilities are strictly organized to maintain sanity as the system grows.

  • core/: Foundational OS & User defaults (Bootloader, Audio, Bluetooth, core system features).
  • features/: Isolated modules containing Nix logic and raw dotfiles.
    • features/apps/: App-specific configs (e.g., features/apps/btop/, features/apps/kitty/), each containing their own default.nix and standalone config/ directory mapped via Home Manager.
    • features/desktop/: Desktop environment components (e.g., Hyprland, Waybar).
    • features/scripts/utils/: Consolidated repository for all custom Nomarchy bash scripts, centrally packaged and injected into the user's PATH with correct dependencies.
  • themes/: The global theming engine. It holds pure color data and logic. Theme-specific app layouts (like a custom Waybar layout) are stored directly inside the app's feature folder, solving the matrix problem of theming.

📥 Installation

Verify the experience without touching your hardware:

./bin/utils/nomarchy-test-installer

This builds a full graphical VM of the installer environment. Once inside, click the Install Nomarchy icon or run nomarchy-install.

2. Build the Installer ISO

To install on physical hardware, generate your own bootable image:

nix build .#nixosConfigurations.installerIso.config.system.build.isoImage

The ISO will be located at ./result/iso/nixos-*.iso. Flash it to a USB drive and boot.

3. Run the Installer

Once booted into the Live environment, launch the installer:

nomarchy-install

The wizard will guide you through:

  • Networking: An interactive wizard to connect to Wi-Fi if needed.
  • Hardware: Optimized profiles for Dell XPS, Framework, Apple T2, and more.
  • Storage: Choice between Standard Ext4 or Encrypted BTRFS with optional Impermanence.
  • Localization: Searchable timezones and keyboard layout selection.

🛠️ Configuration & Usage

Nomarchy uses a "Downstream" model. After installation, your configuration lives in /etc/nixos/ and is split into three main parts:

1. Distro Core (Upstream)

Managed via the public Git repository. This is the engine. You should generally not modify files here.

2. Your System (system.nix)

Add system-wide packages, services, and hardware tweaks here. Example: Adding a persistent directory for Docker if using Impermanence:

environment.persistence."/persist" = {
  directories = [ "/var/lib/docker" ];
};

3. Your User Environment (home.nix)

Add user-level packages, aliases, and dotfiles here. Example: Overriding the default terminal:

nomarchy.home.terminal = "kitty";

Applying Changes

After editing your files, apply them instantly. IMPORTANT: Nomarchy requires the --impure flag for evaluation. You MUST use the following aliases rather than standard NixOS commands:

sys-update  # Rebuilds the NixOS system (Runs: sudo nixos-rebuild switch --flake .#default --impure)
env-update  # Reloads your Home Manager environment (Runs: home-manager switch --flake .#default --impure)

🚀 Commands & Keybindings

Keybinding Action
Super + Space App Launcher (Walker)
Super + Shift + Space Nomarchy Menu (Walker)
Super + Ctrl + Space Background Selector (Walker)
Super + Shift + Ctrl + Space Theme Selector (Walker)
Super + Alt + Space Toggle Top Bar (Waybar)

Utility Scripts

Nomarchy includes dozens of productivity scripts available in your PATH. Some highlights:

  • nomarchy-sync push <repo>: Backup your setup to Git.
  • nomarchy-theme-bg-next: Cycle to the next wallpaper in the current theme.
  • nomarchy-menu: The central hub for all utilities and pickers.

Built with ❤️ using NixOS, Hyprland, Stylix, and the spirit of Omarchy.
