日语模式下把 - 让给长音符（ー）输入，同时禁掉 -/= 的候选翻页： - 罗马字方案接受 VK_OEM_MINUS，set_raw_input 不再把 - 过滤掉； 罗马字表里本来就有 - 到 ー 的条目，只缺按键准入。 - n 后面接 - 时按辅音处理，让前面的 n 收成 ん，避免 n- 卡在 pending。 - 空编码时单独按 - 也起头组合，候选框第一项是 ー、第二项是普通 -。 - 组词流程同样适用：判据只看日语模式加组合状态，不再走翻页和词转字。 - -/= 在日语模式下不翻页，_ = + 这些没有假名写法的字符退回标点上屏， 并把 = _ 补进服务端的标点集合，和 TSF 侧保持一致，否则会等不到回包。 TSF 侧的影子分类、IsVirtualKeyNeed(ForFreshComposition) 和服务端按键策略 三处同时改，统一以配置项 input_mode == japanese 为判据（R 模式不在范围内， TSF 侧看不到临时会话，用会话类型判断会让两侧分类打架）。
Input engine (engine/)
The C++ conversion engine behind Metasequoia IME for Windows: input sessions, candidate lookup, helpcodes, the shared contracts and the voice module.
This directory used to be a submodule of metasequoiaime/MSIME-Engine. It is now a component of this repository, a sibling of server/, ui/, windows/ and installer/. Its upstream commit, and exactly what the Windows specialization removed, are recorded in UPSTREAM.md. Treat it as first-party code: reviewed, formatted and tested like anything else here, no longer merged from upstream.
| Directory | Purpose |
|---|---|
core/, quanpin/, shuangpin/, english/, japanese/ |
Input sessions and candidate lookup |
contracts/ |
The authoritative IPC wire format, dictionary format, punctuation policy and WebView message schema |
helpcode/ |
Helpcode (形码) tables and generators |
local_modes/, providers/, user_dictionary/ |
Local modes, online candidate sources, the user dictionary |
voice/ |
Recording, WAV encoding, recognition and text cleanup; builds independently |
googlepinyinime-rev/, utfcpp/, voice/third_party/ |
Vendored third-party code, kept in its upstream formatting and licence |
Integration is through <metasequoia/session.h>. See runtime architecture.
Build
The product build does not build this directory on its own: server/CMakeLists.txt pulls it in with add_subdirectory, so CI compiles and exercises the engine through the server and the TSF frontend. After changing something here, run the server's build and tests.
Building it standalone still works and is much faster while working on the engine. Dependencies are CMake 3.25+, a C++17 compiler, Boost, fmt, spdlog and SQLite3.
vcpkg install --triplet x64-windows-static
cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE="$env:VCPKG_INSTALLATION_ROOT/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static
cmake --build build --config Release --parallel
ctest --test-dir build -C Release --output-on-failure --timeout 20
ctest runs every engine target registered in the root CMakeLists.txt: the segmentation, IPC and punctuation contracts, the platform API, data paths, runtime isolation, dictionary state and the per-mode session tests. tests/ additionally holds a separate Windows-only project that is not part of that build — add new tests to the registered targets so they actually run.
Formatting is driven from the repository root by scripts/format.sh, using the .clang-format in this directory (voice/ has its own with a wider column limit). The vendored third-party trees and the generated headers are excluded.
Contract rules
The IPC wire format, opcodes, voice framing and WebView message definitions live in contracts/ and are the single source of truth. Consumers include the same headers; do not restate them on either side. Dictionary naming is defined by contracts/dictionary/format.json, shared with the repository root's scripts/dictionary_product.py.
Data and licensing
The dictionaries are neither stored nor built here. They arrive as a release pinned by tag and digest in product-lock.json and are downloaded at build time; the pipeline that produced them left with the specialization. Per-source licensing is tracked in NOTICE.md — read it before redistributing the built databases.
Recognition goes through a cloud provider; local Whisper inference was removed. The only committed model is voice/assets/models/silero_vad.onnx, loaded solely by the standalone Windows host that is off by default.
Licence
GPL-3.0. Vendored googlepinyinime-rev, utfcpp and voice/third_party/miniaudio keep their upstream licences.
