Full replacement of the previous iteration, rebuilt around three ideas:
- Pure evaluation: theme-state.json lives inside the flake and is read
via the nomarchy.stateFile option — no --impure, ever.
- All-Home-Manager theming: `nomarchy-theme-sync apply` writes the JSON
and runs `home-manager switch`; every theme change is one atomic,
rollbackable generation. Wallpaper (swww) is the sole runtime piece.
- Flat, downstream-first layout: modules/{nixos,home} with one
options.nix each, exported as nixosModules/homeModules + overlay +
flake template; system (nixos-rebuild) and desktop (home-manager
switch) rebuild paths are fully split.
Ships 21 themes imported from the previous iteration (palettes,
wallpapers, btop themes, six whole-swap Waybar identities), Stylix for
the GTK/Qt/cursor long tail, a live ISO target with offline theme
switching, and docs/TESTING.md with the QEMU verification workflow.

# Nomarchy theming engine.

# nomarchy.stateFile (theme-state.json, inside the consuming flake) is
|

# ingested at evaluation time — pure, because flake files are store
|
|
# paths — and exposed to every other module as `config.nomarchy.theme`.
|
|
#
|
|
# Theme changes are fully Home Manager managed: `nomarchy-theme-sync
|
|
# apply <theme>` writes the JSON and runs `home-manager switch`, baking
|
|
# everything (Hyprland, Waybar, Ghostty, btop, Stylix) into one
|
|
# read-only generation. No runtime patching, no partial states; theme
|
|
# history is generation history.
|
|
#
|
|
# The one runtime exception is the wallpaper (swww is imperative by
|
|
# nature): applied at session start, after every switch (hook below),
|
|
# and cycled instantly with `nomarchy-theme-sync bg next`.
