Auto Dark Mode is a Windows desktop utility that automatically switches between dark and light system themes. In production it operates as a multi-process system: a WinUI 3 settings app (AutoDarkModeApp), a background service with system tray icon (AutoDarkModeSvc running under Windows Forms Application.Run), a lightweight CLI shell for IPC commands (AutoDarkModeShell), and self-update tooling split between a legacy C# updater and two Rust components (adm-updater-rs, adm-downloader-rs). The service evaluates multiple triggers — custom time schedules, sunrise/sunset from geolocation or manual coordinates, Windows Night Light state, ambient light sensor lux readings, battery/energy saver state, GPU load, process blocklists, and system idle — then applies theme changes across Windows components: system/app theme, per-monitor wallpapers, accent color, taskbar color, cursors, touch keyboard, color filters, and user-defined scripts. UI and service communicate over named-pipe IPC with a command/response protocol; configuration persists in YAML files watched via FileSystemWatcher and WMI events. This is purely an application repository; bundled GeoJSON assets and geolocation features serve the scheduling feature, not data research. Architecturally the codebase shows genuine craftsmanship: a governors pattern (TimeSwitchGovernor, NightLightGovernor, AmbientLightGovernor) separates switch-decision logic from switch-execution, switch components (ISwitchComponent/BaseComponent) isolate individual theme pieces, a postpone manager coordinates blocking conditions (GPU, idle, processes, notifications) with expiry callbacks, and a config-update event system decouples YAML changes from feature reactions. The UI follows MVVM with CommunityToolkit, dependency injection, and 25+ localized locales. Maintenance is active with recent commits and an issue-triage workflow, but technical drift is medium: commented-out ZeroMQ code and legacy updater logic remain, updater behavior is triplicated across C# and Rust, localization coverage has drifted (many locales contain untranslated English strings), and core features depend on undocumented Windows COM interfaces (IThemeManager2) and build-version checks that may break with future Windows updates.
This repository is a CSS theme for the Obsidian note-taking application, designed to replicate the visual aesthetic of the Things 3 task manager. The codebase consists of a single `theme.css` file that overrides Obsidian's default styling using CSS custom properties, class overrides, and media queries. It provides both light and dark color schemes, custom checkbox icons via CSS mask images, progress bar coloring based on percentage, and extensive integration with community plugins like Kanban, Calendar, Todoist, and Checklist. The theme also includes a comprehensive set of user-customizable settings exposed through the Style Settings plugin. This is a pure presentation layer with no application logic, data processing, or dependencies beyond Obsidian itself.
Ultrachromic is a CSS theme for the Jellyfin media server that provides a modular system of CSS overrides to customize the appearance of the Jellyfin web interface. It consists of multiple CSS files that can be imported in a specific order to build a theme, including base styling, accent colors, rounding, progress bars, and various visual effects. The theme uses CSS variables for easy customization and includes presets that replicate the appearance of older chromic themes. It demonstrates good use of modern CSS features such as CSS variables, animations, backdrop-filter, and media queries.
