KIDult2226 1c5cae105b feat(display): per-output ICC color profiles and color temperature
Rebuild of #3388 on current master: the previous branch was cut from an
older base and reverted unrelated fixes in the gamma stack and the display
settings UI.

ICC profiles:
- core/internal/icc: ICC v2/v4 parser (TRC, LUT8/16 and parametric curves,
  vcgt, description/version/color space) plus gamma ramp generation, with
  synthetic coverage and optional vendor-profile tests (ICC_TEST_DIR).
- wayland manager: load iccProfiles from the compositor's DMS config dir,
  build the ramp from the profile when one is set (falling back to the
  temperature ramp when it is missing or unparsable), and re-apply on
  output hotplug and after resume.
- ICC ramps apply while the night light schedule is disabled; outputs
  without a profile keep an identity ramp.
- desc/mluc offsets are validated before slicing, so a malformed profile
  returns an error instead of panicking the daemon.

Per-output temperature:
- outputTemps in the same config; SetOutputTemp accepts 1000-10000K and the
  Display Config slider exposes 3000-10000K, which matters for displays
  calibrated at a higher white point (e.g. a 7000K profile).

Gamma control lifecycle:
- needsControls() now keeps the controls alive for configured ICC profiles
  and per-output temperatures, so toggling the night light off no longer
  destroys the controls and drops the ramps.
- Re-apply paths clear the per-output dedup state instead of adding a
  manager-level guard, which would have suppressed contrast-only writes and
  the post-resume forced resend (#1235), and left a recreated control
  without a ramp.
- Monitor sleep/disconnect still re-establishes controls when an output
  comes back.

IPC / CLI / UI:
- wayland.icc.{getStatus,apply,remove,listOutputs,setTemp,getTemps}
- dms icc list | info <file> | apply <output> <file> | remove <output> | status
- Display Config output card gains a Color Profile row (browse/apply/remove
  with description, version, color space and active state) and a per-output
  color temperature slider, backed by Services/ICCService.qml.

Config path:
- DMSConfigDir() follows the compositor layout (niri/dms, hypr/dms,
  mango/dms) via the shared compositor detection and utils.XDGConfigHome(),
  replacing the hardcoded niri path in both the manager and `dms icc`.

Tests: TZ=UTC go test ./... (60 packages ok), including red/green coverage
for the icc parser bounds checks and needsControls().

DMS Quickshell Interface

QML-based desktop shell interface for DankMaterialShell providing panels, widgets, and overlays.

See root README for project overview and installation.

Architecture

Modular QML Structure

  • Modules/ - UI components (panels, widgets, overlays)
  • Services/ - System integration singletons (audio, network, bluetooth)
  • Widgets/ - Reusable UI controls
  • Common/ - Shared resources and themes

Technology Stack

  • Quickshell - QML-based shell framework
  • Qt/QtQuick - UI rendering and controls
  • Material Design 3 - Design system and theming

Development

Run the shell:

quickshell -p quickshell/

Code formatting:

qmlfmt -t 4 -i 4 -b 250 -w path/to/file.qml
make lint-qml  # Run from repo root; requires quickshell/.qmlls.ini (generated by `qs -p quickshell/`)
               # Uses Qt 6 qmllint. Override path with QMLLINT=/path/to/qmllint if needed.
               # Auto-detects `qmllint6`, Fedora's `qmllint-qt6`, `/usr/lib/qt6/bin/qmllint`, then `qmllint`.

Components

Panels & Bars

  • Modules/TopBar/ - Multi-monitor status bars with workspace switching
  • Modules/DankBar/ - Customizable widget bar with plugin support
  • Modules/Dock/ - Application dock with window management

System Controls

  • Modules/ControlCenter/ - WiFi, Bluetooth, audio, display settings
  • Modules/Notifications/ - Notification center with popups

Overlays

  • Modules/Spotlight/ - Application and file launcher
  • Modules/Overview/ - Workspace overview
  • Modules/Lock/ - Screen lock system

Utilities

  • Modules/ProcessList/ - System monitoring and process management
  • Modules/Calendar/ - Calendar widget with event sync
  • Modules/Weather/ - Weather display

Services

Singletons providing system integration:

Media & Audio

  • AudioService - PipeWire/PulseAudio volume and device control
  • MprisController - Media player integration

Network

  • NetworkService - NetworkManager WiFi control
  • BluetoothService - BlueZ Bluetooth management

Display

  • DisplayService - Brightness control and night mode
  • WallpaperService - Wallpaper management and effects

System

  • BatteryService - Battery status and power profiles
  • IdleService - Idle detection and inhibit locks
  • ClipboardService - Clipboard history with images
  • DgopService - System metrics (CPU, RAM, GPU)

Integration

  • NiriService - Niri workspace integration
  • HyprlandService - Hyprland workspace integration
  • PluginService - Plugin discovery and lifecycle

Widgets

Reusable Material Design 3 components in Widgets/:

  • DankIcon - Icon component with Material font
  • DankSlider - Enhanced slider with animations
  • DankToggle - Toggle switch component
  • DankTabBar - Tab bar implementation
  • DankGridView - Grid layout with adaptive columns
  • DankListView - Scrollable list view
  • DankTextField - Text input with validation
  • DankDropdown - Dropdown selection
  • DankPopout - Base for overlay components
  • StateLayer - Material interaction states

Theming

Dynamic Color Schemes

Wallpaper-based theming using matugen:

import qs.Common

Rectangle {
    color: Theme.container
    border.color: Theme.outline
}

Theme singleton provides Material Design 3 color system, spacing, fonts, and elevation.

Application Themes

Templates in scripts/templates/ generate themes for:

  • GTK 3/4
  • Qt5/Qt6
  • Alacritty, Kitty, Ghostty, Foot, Wezterm terminals
  • Neovim
  • VSCode/VSCodium
  • Firefox

Multi-Monitor Support

Per-monitor panel instances using Quickshell Variants:

Variants {
    model: Quickshell.screens
    PanelWindow {
        screen: modelData
        // Per-screen configuration
    }
}

Workspace switchers adapt to compositor (Niri/Hyprland).

Plugin System

External plugins in ~/.config/DankMaterialShell/plugins/:

Widget plugins - UI components in DankBar Daemon plugins - Background processes without UI

Plugin manifest (plugin.json):

{
    "id": "pluginId",
    "name": "Plugin Name",
    "version": "1.0.0",
    "type": "widget",
    "component": "./Widget.qml",
    "settings": "./Settings.qml",
    "permissions": ["settings_read", "settings_write"]
}

Plugins access pluginService for persistent data:

pluginService.savePluginData("pluginId", "key", value)
pluginService.loadPluginData("pluginId", "key", defaultValue)

IPC Integration

Backend IPC socket communication:

import Quickshell.Io

Process {
    command: ["dms", "ipc", "call", "spotlight", "toggle"]
    running: true
}

Common IPC commands exposed through services for reactive property bindings.

Code Conventions

Component Structure:

import QtQuick
import Quickshell
import qs.Common
import qs.Services

Item {
    id: root

    property type name: value

    signal customSignal(type param)

    Component { /* children */ }
}

Services (Singletons):

import QtQuick
import Quickshell
pragma Singleton
pragma ComponentBehavior: Bound

Singleton {
    id: root

    property bool featureAvailable: false
    property type currentValue: defaultValue

    function performAction(param) { /* implementation */ }
}

Guidelines:

  • Use Theme.propertyName for consistent styling
  • Bind directly to service properties for reactivity
  • Use DankIcon for all icons
  • Implement feature detection and graceful degradation
  • 4-space indentation, no unnecessary comments
