darmanandClaude Opus 5 e38a8403ac feat(quickshell): add hyprchrome bar with collapsible panels 
A second shell chrome under dotfiles/quickshell/hyprchrome, built around a
BarPanel that carries TWO renderings of its data: the default children are the
expanded detail view, `summary` the terse one shown while collapsed. Both stay
bound to the same sources, so the densities cannot disagree, and the panel
cross-fades between them while its height animates.

Panels: HostPanel (hostname, user, timezone, clock), VitalsPanel (CPU load and
temperature, memory, GPU load and temperature, all metered), TrayPanel (system
tray, self-sizing). HyprChromeBar pins them to DP-2 and owns `expanded` for the
whole rail — SUPER A, via GlobalShortcut "chrome".

GPU busy comes off sysfs rather than the node_exporter scrape VitalsData
already does: the hwmon collector carries the card's temps, power and clocks
but not its utilisation.

The bar's height binds to each panel's `targetHeight` — where it will settle,
not where the animation currently is — because the exclusive zone is
window-sized by default, and binding to the animated height relayouts every
tiled window on the output twelve times per toggle. The zone follows the target
immediately so the desktop reflows once, at the start; the surface itself
shrinks only after the panels finish, or it would clip them mid-animation.

DebugWindow stages a widget in the middle of the secondary monitor
(SUPER CTRL D), masked so only the staged widget takes pointer input.

Raw Blame History

{ lib, pkgs, config, inputs, ... }:
# Hyprland config migrated from github.com/darman96/hyprland-dotfiles (the
# hyprlang `hypr/*.conf` files) into the home-manager lua-style `settings`
# (configType defaults to "lua" on stateVersion 26.05). Each top-level
# `settings` attr becomes an `hl.<name>(...)` call in ~/.config/hypr/hyprland.lua;
# `_args` lists become multi-arg calls, `_var` locals become `local x = ...`, and
# `lib.generators.mkLuaInline` values render as raw Lua expressions.
#
# Imported by home.nix. System-level Hyprland enable (session entry, portals)
# lives in ../../services/desktop/desktop-hyprland.nix; this manages the user's
# own hyprland.lua.
#
# Deliberately NOT migrated:
# - hyprbars.conf: config for the third-party `hyprbevelbars` plugin, which
# isn't packaged in nixpkgs. Load it via
# `wayland.windowManager.hyprland.plugins` and re-add its config once
# available. (hyprredsquare.conf's plugin was renamed hypr-chrome and
# rewritten since - it's wired in below via the `hypr-chrome` flake
# input instead, with its own `plugin.hyprchrome` config.)
# - hyprqt6engine.conf + `QT_QPA_PLATFORMTHEME=hyprqt6engine`: terra themes Qt
# through qtct/Dracula in home.nix, so that env var is left off to avoid a conflict.
# - hyprlock.conf: a separate program (use `programs.hyprlock` if wanted).
# - the duplicate pamixer/amixer + `.wob` volume binds: kept only the clean
# pipewire `wpctl`/`playerctl` set (no wob overlay is configured here).
# - `XDG_MENU_PREFIX=arch-` and `VCPKG_ROOT`: Arch-/user-specific.
# Many binds reference apps/scripts not packaged on terra yet (vivaldi-stable,
# dolphin, vicinae, grimblast, waypaper, discord, gitkraken, qbz,
# ~/.config/scripts/start-communications.sh); add them separately.
