Vicinae is a cross-platform desktop launcher and productivity tool written in modern C++20/23 with Qt6 and QML, inspired by Raycast. It provides a single keyboard-driven interface for launching applications, searching files, managing clipboard history, switching windows and workspaces, controlling media, running script commands, browsing fonts, picking emoji, and more. The system runs as a background server process with a CLI client, a file indexing subprocess, and a browser extension for tab management. It features a first-class extension system using TypeScript and Node.js, a custom fuzzy search library, an XDG desktop entry parser, encrypted clipboard storage, and deep platform integration for Linux (Wayland/X11, GNOME, KDE, Hyprland), macOS, and Windows. The architecture is modular with abstract service backends and a service registry for dependency injection.
wl-clipboard-rs is a Rust library providing safe access to the Wayland clipboard through the ext-data-control and wlr-data-control protocols. It consists of a library crate (wl-clipboard-rs) that handles clipboard operations and a tools crate (wl-clipboard-rs-tools) providing terminal utilities: wl-copy (copy to clipboard), wl-paste (paste from clipboard), and wl-clip (xclip-like utility). The library abstracts over different Wayland clipboard protocol versions, manages connections to the compositor, handles MIME type negotiation, and serves clipboard requests. The architecture separates concerns into copy, paste, utils, common connection logic, data control abstraction, and seat data management modules.
Clipy is a macOS clipboard extension app that lives in the menu bar. It provides clipboard history management, text snippet storage and quick paste, OCR for image-based clipboard content, and customizable global hotkeys to trigger history menu, snippet editor, or paste actions. The app monitors NSPasteboard using a timer, deduplicates entries, and stores them in a local SQLite database (via GRDB wrapper SQLiteData), with a legacy Realm database still present for migration. UI is built with a mix of SwiftUI (settings panes) and AppKit (snippet editor, menu). Dependency injection via swift-dependencies and reactive storage via swift-sharing are used throughout. The architecture is well-modularized with repository and service layers, extensive unit tests, and a migration system for both database schema and user defaults. However, the project shows signs of drift: legacy Realm code and XIB files persist, localization strings may be out of sync, and the last commit date is anomalous (future date) suggesting the project may be unmaintained despite a large user base.
