RIME: Rime Input Method Engine
Rime with your keystrokes.

Features
- A modular, extensible input method engine in cross-platform C++ code, built on top of open-source technologies
- Covering features found in a large variety of Chinese input methods, either shape-based or phonetic-based
- Built with native support for Traditional Chinese, conversion to Simplified Chinese and other regional standards via OpenCC
- Rime input schema, a DSL in YAML syntax for fast trying out innovative ideas of input method design
- Spelling Algebra, a mechanism to create variant spelling, especially useful for Chinese dialects
- Support for chord-typing with a generic Qwerty keyboard
