Bernardo Magri 71f37bfc30 feat(keyboard): interactive new-keyboard layout prompt + persist
The runtime-remember complement to nomarchy.keyboard.devices. Set
nomarchy.keyboard.layouts (candidate layouts) and a nomarchy-keyboard-watch
daemon runs (exec-once): it polls hyprctl devices, and when a keyboard
connects after login that isn't declared and hasn't been chosen before, it
pops a rofi layout picker, applies the choice via hyprctl switchxkblayout (an
index into the candidate set carried by input.kb_layout), and remembers it
per-device in ~/.local/state -- re-applied silently on later reconnects. The
boot-time set (incl. the built-in keyboard) is never prompted.

Pure bash + jq/hyprctl/rofi (all in the session PATH); state lives outside
the flake (a stateful runtime piece by design). Eval + bash-syntax verified;
the hotplug behaviour needs an on-hardware test.

# Nomarchy
**The rock-solid reproducibility of NixOS 26.05. The out-of-the-box polish of
Omarchy/Omakub.** One JSON file rules the look of the entire desktop; every
theme change is a Home Manager generation — atomic, rollbackable, never
partial.
```
┌──────────────────────────────────────────────────────────────────────────┐
│ theme-state.json (single source of truth) │
│ lives INSIDE your flake checkout, git-tracked │
└───────────────────────────────────┬──────────────────────────────────────┘
nomarchy-theme-sync apply gruvbox

2. runs `home-manager switch` (no sudo, no system rebuild)

## 1. Layout
Flat on purpose. Two module trees, one options file each, no hidden layers.

**Rule of thumb:** `modules/` is the distro (reusable, no machine specifics),
`hosts/` is a machine, `themes/` is data, `pkgs/` is code, `tools/` is
maintainer-only. If a new file doesn't obviously belong to one of those, it
probably shouldn't exist.
## 2. Try it first (live ISO)
Boot the full desktop from a USB stick or VM without installing anything:
```sh
nix build .#nixosConfigurations.nomarchy-live.config.system.build.isoImage
# → result/iso/*.iso — dd to a stick, or boot it in QEMU:
tools/test-live-iso.sh
```
The live session auto-logs-in, seeds the flake at `~/.nomarchy`, and pins
the locked inputs into the ISO store — so theme switching (including the
`home-manager switch` it triggers) works **offline**, exactly like on an
installed system. Verification checklist: [docs/TESTING.md](docs/TESTING.md).
Like what you see? **`nomarchy-install`** (in a terminal) walks you through
installing to disk: pick a disk, LUKS2 full-disk encryption **by default**
(in exchange the desktop logs in passwordless — the passphrase already
gates the machine), user + hostname + timezone, hardware autodetection
(DMI → nixos-hardware profile), a hibernation-ready swapfile sized to RAM,
then disko partitions (GPT + ESP + BTRFS subvolumes incl. `@snapshots`
snapper timeline snapshots are on) and `nixos-install` runs — **without a
network** when the ISO was built from a clean tree (the target's
`flake.lock` is composed from the rev the ISO carries). The installed
machine gets the standard downstream layout: the flake at `~/.nomarchy`
(`/etc/nixos` symlinks to it), one `mkFlake` call, your
`system.nix`/`home.nix`. First boot lands in the fully themed desktop —
the installer pre-activates the Home Manager generation. UEFI only for now.
## 3. Using Nomarchy on your machine (downstream)
Nomarchy is consumed as a flake input — you never fork or edit this repo:
```sh
mkdir my-machine && cd my-machine
nix flake init -t "git+https://git.bemagri.xyz/bernardo/nomarchy.git?ref=v1"
```
You own two files day-to-day: `system.nix` and `home.nix` (plus
`theme-state.json`, written by the CLI). Your `flake.nix` is set up once —
later by the installer — and never hand-edited; it's a single call:
```nix
outputs = { nomarchy, ... }:
nomarchy.lib.mkFlake {
src = ./.;
username = "me";
hardwareProfile = "framework-13-7040-amd"; # optional, nixos-hardware name
};
```
| `mkFlake` arg | Default | Purpose |
|---|---|---|
| `src` | — (required) | Your flake directory (`./.`) |
| `username` | — (required) | Login name; flows into `system.nix` and names the HM config |
| `hardwareProfile` | `null` | One [nixos-hardware](https://github.com/NixOS/nixos-hardware) module name, or a list of them (pinned + tested by Nomarchy; unknown names fail with suggestions) |
| `system` | `"x86_64-linux"` | Platform |
(Power users can skip `mkFlake` and wire `nixosModules.nomarchy` /
`homeModules.nomarchy` / `overlays.default` by hand — the wrapper is sugar.)
Two deliberately separate rebuild paths:
```sh
sudo nixos-rebuild switch --flake .#default # system: rare
home-manager switch --flake .#me # desktop: every theme change, no sudo
```
Day-to-day you'll use the shipped shortcuts instead:
```sh
sys-update # nix flake update + system rebuild (BTRFS snapshot first when available)
home-update # home-manager switch (no flake update, no sudo)
```
**Order matters when pulling distro updates.** `home-update` does *not*
touch the lock — it rebuilds the desktop against the **current**
`flake.lock`. A new Nomarchy revision (new keybinds, theming, modules)
arrives only when the lock is updated, which `sys-update` does
(`nix flake update`). So to pull an update that affects the desktop layer:
run `sys-update` **first** (updates the lock + rebuilds the system), **then**
`home-update` (re-applies the desktop against the new lock). Doing them in
the other order rebuilds the desktop against the *old* inputs and silently
skips the new home-side changes. After a home-side keybind/config change,
also `hyprctl reload` (or relogin) so the running session re-reads it.
Override anything via the `nomarchy.*` surface or plain NixOS/HM options:
appearance (gaps/colors/fonts) changes through `nomarchy-theme-sync`,
behaviour (input/misc/monitor/chrome) is `mkDefault` so a plain `home.nix`
assignment wins, and bind/exec-once lists concatenate. Full guide with
examples: **[docs/OVERRIDES.md](docs/OVERRIDES.md)**.
| Option | Default | Purpose |
|---|---|---|
| `nomarchy.stateFile` | — (required) | Path to your theme-state.json |
| `nomarchy.terminal` | `"ghostty"` | Terminal for keybinds and `$TERMINAL` |
| `nomarchy.keyboard.layout` | `"us"` | XKB layout for the Hyprland session (installer writes the matching `services.xserver.xkb` in system.nix; the console + LUKS prompt follow via the distro default) |
| `nomarchy.keyboard.variant` | `""` | XKB variant for the session |
| `nomarchy.keyboard.devices` | `{}` | Per-device layout overrides (Hyprland `device` blocks keyed by `hyprctl devices` name) — e.g. an external keyboard with its own layout/variant |
| `nomarchy.keyboard.layouts` | `[]` | Extra candidate layouts; when set, a watcher prompts (rofi) for a layout on a newly-connected keyboard and remembers it per-device |
| `nomarchy.hyprland.enable` | `true` | Nomarchy's Hyprland config |
| `nomarchy.waybar.enable` | `true` | Nomarchy's Waybar |
| `nomarchy.rofi.enable` | `true` | Themed rofi launcher + `nomarchy-menu` dispatcher |
| `nomarchy.swaync.enable` | `true` | swaync notifications, themed |
| `nomarchy.idle.enable` | `true` | hyprlock + hypridle (idle lock 5 min, display off 10, suspend 30) |
| `nomarchy.yazi.enable` | `true` | yazi TUI file manager, themed + curated plugins |
| `nomarchy.osd.enable` | `true` | swayosd on-screen display for volume/brightness/mute |

| `nomarchy.stylix.enable` | `true` | GTK/Qt/cursor theming |
| `nomarchy.fastfetch.enable` | `true` | fastfetch fronted by the themed Nomarchy logo |
| `nomarchy.keys.enable` | `true` | gpg-agent fronting SSH + pinentry-qt |
| `nomarchy.displays.enable` | `true` | nwg-displays interactive monitor arranger (helper for `nomarchy.monitors`) |
| `nomarchy.monitors` | `[]` | Declarative per-output layout → Hyprland `monitor` rules (applied on hotplug); `,preferred,auto,1` wildcard kept as fallback |
| `nomarchy.themesDir` | Nomarchy's `themes/` | Where per-theme app overrides are probed |
| `nomarchy.system.plymouth.enable` | `true` | Branded boot splash, background from the theme JSON (recolors on system rebuilds) |
| `nomarchy.system.fileManager.enable` | `true` | Thunar GUI + gvfs/tumbler/udisks2 (the "open folder" handler) |
| `nomarchy.system.greeter.enable` | `true` | greetd/tuigreet |
| `nomarchy.system.greeter.autoLogin` | `null` | Auto-login this user into Hyprland (installer sets it on LUKS machines) |
| `nomarchy.system.audio.enable` | `true` | Pipewire stack |
| `nomarchy.system.bluetooth.enable` | `true` | Bluetooth + blueman |
| `nomarchy.system.snapper.enable` | `false` | Hourly/daily BTRFS timeline snapshots + `nixos-rebuild-snap` (installer enables it; no-op unless root is BTRFS) |
| `nomarchy.system.power.enable` | `true` | Active power management (see below) |
| `nomarchy.system.power.backend` | `"ppd"` | `"ppd"` (power-profiles-daemon + menu/Waybar switcher) or `"tlp"` (deeper battery tuning, no switcher) — mutually exclusive |
| `nomarchy.system.power.laptop` | `false` | Marks a laptop, gating battery-only features; the installer sets it when a battery is present |
| `nomarchy.system.power.thermal.enable` | `false` | thermald (Intel-only); the installer enables it on a GenuineIntel CPU |
| `nomarchy.system.power.batteryChargeLimit` | `null` | Stop charging at this % (e.g. `80`) where the hardware supports it; needs `power.laptop` |
Beyond the `nomarchy.*` surface, the system layer turns on the usual
desktop services with `lib.mkDefault` (override natively). One worth
calling out: **`services.fwupd.enable`** is on by default for firmware
updates via LVFS — it only refreshes metadata, never flashes on its own,
so run `fwupdmgr update` to apply. Disable with `services.fwupd.enable =
false;` on machines without real firmware (VMs/headless).
## 4. How theming works
### Pure JSON ingestion
The trap with "read a mutable file from Nix" is pure evaluation: flakes
cannot read arbitrary `$HOME` paths without `--impure` (the old prototype
required it — never again). Nomarchy's convention: **the state file lives
inside the consuming flake** and is wired via
`nomarchy.stateFile = ./theme-state.json;`. Reading it is pure — it's flake
source. It must be git-tracked (`nomarchy-theme-sync` runs
`git add --intent-to-add` after every write as a safety net).
### One change = one generation
`nomarchy-theme-sync apply <theme>` merges the preset into the JSON and runs
`home-manager switch` (override the command with `$NOMARCHY_REBUILD`, or pass
`--no-switch` to only write). Everything is baked: Hyprland, Waybar, Ghostty,
btop, and — via Stylix, mapped onto base16 roles — GTK, Qt, cursors and
fonts. No runtime patching means no partial states, and `home-manager
generations` is also your theme history. Waybar even restyles in place: it
re-reads `style.css` when the symlink flips.
The **wallpaper** is the one runtime piece (awww — nixpkgs' swww — is
imperative; nothing in Nix consumes the path): applied at session start and
after every switch via a tiny activation hook, cycled instantly with
`bg next`.
### Per-theme app assets (`themes/<slug>/`)
Recoloring covers 95% of theming; the rest is one optional assets directory
per theme — a single place to look, unlike the old distro's split:
| Asset | Mechanism |
|---|---|
| `backgrounds/` | wallpapers; empty `wallpaper` in the state means "first one"; `bg next` cycles |
| `btop.theme` | baked into the generation (generated from the palette when absent) |
| `waybar.css` | **whole-swap**: replaces the generated bar style entirely (probed at eval time, self-contained) |
| `waybar.jsonc` | whole-swap for the bar *layout* (must be plain JSON) |
| `rofi.rasi` | **whole-swap**: replaces the generated launcher/menu theme entirely |
Six ported themes ship a `waybar.css` identity (catppuccin, lumon, nord,
retro-82, summer-day, summer-night). Custom user themes can live in
`$NOMARCHY_PATH/themes/` (preset lookup) and `nomarchy.themesDir` (eval-time
asset probe).
## 5. Day-to-day
```sh
nomarchy-theme-sync list # 21 presets (nord, gruvbox, rose-pine, …)
nomarchy-theme-sync apply kanagawa # whole desktop, one generation (~a switch)
nomarchy-theme-sync set ui.gapsOut 16 # tweak one knob (also a switch)
nomarchy-theme-sync bg next # cycle wallpapers — instant, no rebuild
nomarchy-theme-sync bg auto # back to the theme's default wallpaper
nomarchy-theme-sync get colors.accent
sys-update # update inputs + rebuild the system (snapshots first)
home-update # rebuild just the desktop layer
```
Keybinds: `SUPER+Return` terminal · `SUPER+D` launcher · `SUPER+T` theme
picker · `SUPER+SHIFT+T` next wallpaper · `SUPER+X` power menu ·
`SUPER+E` file manager (yazi) · `SUPER+N` notifications · `SUPER+CTRL+V`
clipboard history · `SUPER+Q`
close · `SUPER+1..9` workspaces · `Print` region screenshot.
## 6. Extending
- **New theme:** drop a JSON into `themes/` (schema = any existing preset),
plus an optional `themes/<slug>/` assets directory.
- **New themed value:** add the key to `theme-state.json` and consume it in
the Nix modules. One place — there is no second renderer to keep in sync.
- **Importing more old-distro palettes:**
`tools/import-palettes.py <palettes-dir> themes/`.
