What it is

Weasel (小狼毫) is the Windows implementation of Rime, an open-source input method engine that enables Chinese character input via multiple schemes (Pinyin, Zhuyin, Cangjie, etc.). It provides a modern IME (Input Method Editor) for Windows 8.1–11 with real-time candidate selection, user dictionary management, and customizable UI themes. Multi-component C++ monorepo: RimeWithWeasel/ is the core IME service that interacts with librime; WeaselDeployer/ is the configuration UI (Qt-style dialogs); WeaselIPC/ handles inter-process communication with the input context via named pipes; each component compiles as a separate .exe with shared utilities. Build system uses xmake and NSIS for packaging.

• WeaselIPC/WeaselClientImpl.cpp — Core client-side IPC implementation that bridges TSF/input context with the Rime engine—essential for understanding…
• WeaselIPCServer/WeaselServerImpl.cpp — Server-side IPC handler that processes input and returns composition/candidate data—critical for debugging IPC communication.
• WeaselTSF/Composition.cpp — Text Services Framework integration layer for composing and editing text—necessary for understanding Windows IME integration.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/rime/weasel.git
cd weasel
git submodule update --init --recursive
# Install xmake (https://xmake.io/)
# Install MSVC 2022 or later via Visual Studio
xmake build
# Output binaries in build/windows/x64/release/

Daily commands:

Development build: xmake build --mode=debug. Release build: xmake build --mode=release. Install locally: Run the generated NSIS installer (.exe) or use xmake's install target. Run service: WeaselServ…

Key cautions & unknowns

• Single-maintainer risk — top contributor 84% of recent commits
• GPL-3.0 is copyleft — check downstream compatibility
• Windows version compatibility: IME code uses Win32 APIs that changed between Windows 8.1 and 11; test matrix must include multiple target versions. IPC protocol fragility: Pipe serialization format is tightly…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
