$ show osfans/trime
The repository implements Trime, a fully functional Android input method (IME) based on the Rime input engine. It provides a highly customizable keyboard with YAML-based themes, color schemes, key layouts, and gesture support. The core architecture is a Kotlin/JNI bridge to the native librime library, with a service-based IME lifecycle (`TrimeInputMethodService`), a daemon for Rime session management, and a rich UI layer for candidate display, clipboard, popups, and liquid keyboards. The application also includes a settings interface for schema management, user dictionaries, sync via Storage Access Framework, and clipboard history. The codebase is modular, with clear separation between Rime interaction, theme management, UI delegates, and data persistence, using modern Android patterns (Room, Paging, WorkManager, Coroutines, Kodein DI). It is actively maintained with frequent commits and extensive test coverage for core components. The YAML theme system is particularly sophisticated, featuring typed color resolution with fallback chains and a custom parser that handles anchors and aliases.
The LLM identified 4 files worth highlighting for reuse:
A reusable gesture handling base class that supports tap, long press, swipe, slide, repeat, and double-tap gestures. It is used by KeyView and ToolButton, and can be extracted into any Android project requiring custom gesture detection without external dependencies. The implementation is clean, non-blocking, and handles edge cases like multi-touch and repeat intervals.
A typed color resolution system with fallback chains. It resolves color keys (e.g., 'text_color', 'candidate_text_color') by traversing a list of fallback tables, with cycle detection and default values. This pattern is domain-agnostic and can be reused in any application that needs hierarchical color overrides, such as theming engines or design systems. It is well-tested with unit tests.
A generic finite state machine implementation using boolean states. It provides a clean API for defining states, transitions, and actions. Used internally for QuickBarStateMachine and UnrollButtonStateMachine, but is completely isolated and can be extracted into any project needing simple state management without external dependencies. It supports side effects on state entry/exit.
A utility for traversing the Android Storage Access Framework (SAF) tree with skip and visit filters. It handles permission persistence, directory creation, and file resolution. This component is self-contained and can be reused in any Android app that needs to navigate SAF trees for backup, sync, or file management. It also includes unit tests.
