super_editor is a Flutter framework for building configurable rich text editors, read-only document viewers, and chat/messaging UIs. It provides a document model based on nodes and attributed spans, a single-column layout engine, platform-specific selection/caret/toolbar controls, IME integration, and serialization to/from Markdown, HTML, and Quill Delta. The repository is a monorepo containing the core super_editor package plus supporting packages: attributed_text, super_text_layout, super_keyboard, super_editor_clipboard, and super_editor_spellcheck. It is used in production by apps such as Superlist and ClickUp, and includes example clones of Google Docs, Slack, Quill, Bear, Obsidian, Medium, and iOS Messenger.
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.
librime is the core library of the Rime Input Method Engine, a modular, cross-platform C++ framework for building Chinese and East Asian input methods. It provides a flexible pipeline architecture composed of processors, segmentors, translators, and filters, all configurable via YAML schemas. The library handles dictionary compilation from text to binary trie formats (leveldb and marisa-trie), spelling algebra for variant syllable mapping, and user-specific adaptation through frequency and custom phrase databases. It exposes a stable C API for integration into frontends (e.g., IBus, Squirrel, Weasel) and supports dynamic plugin loading for extensibility. The codebase is well-structured with clear separation of concerns, a component registry pattern, and extensive unit tests. Notable technical strengths include a custom double-array trie implementation (darts-clone), a sophisticated YAML config compiler supporting inheritance and patching, and an event-driven context system for real-time composition state.
This repository provides Chinese input method addons for the Fcitx5 input method framework. It implements Pinyin (including Shuangpin, fuzzy pinyin, stroke filtering, cloud pinyin, prediction) and table-based input methods (Wubi, Cangjie, Erbi, etc.) as Fcitx5 modules. The architecture follows a plugin/addon pattern, with engines handling key events, candidate generation, and text commit. Supporting modules handle punctuation, fullwidth characters, simplified/traditional Chinese conversion (via OpenCC), cloud pinyin (with pluggable backends like Google and Baidu), and pinyin helper (stroke lookup). GUI tools for custom phrase editing and dictionary management are included. The codebase is well-structured, uses modern C++17, and integrates tightly with Fcitx5's event and configuration systems. External dependencies include libime, Qt6 (for GUI), OpenCC, curl, nlohmann_json, and optionally Lua. The project is actively maintained with a comprehensive test suite.
