一方代码在 /W4 下已零警告。剩余警告全部来自上游副本 (googlepinyinime-rev/、vendor/opencc/ 及其捆绑的 marisa)， 按 AGENTS.md 保留上游原格式，有意不改。 - data_path.h、test_pinyin.cpp: _wgetenv 改 _wdupenv_s，返回值 用 optional 包一层，由 unique_ptr 负责 free - quanpin_dictionary.cpp: 去掉条件表达式内的赋值。外层查询原本 只用其真假，reset_cache_if_database_changed() 可能使其失效， 故保留重取 - build_sql_for_checking_word: 删掉从未使用的 jp 形参 - 未使用的 catch 形参、int/size_type 符号不匹配 - wav_writer.h: 形参 sample_rate 遮蔽同名命名空间常量，改名 requested_sample_rate；默认值改为直接引用该常量，去掉魔数 - pinyin_file_io.h: _wfopen/_wopen 改 _wfsopen/_wsopen_s 最后一项没有用微软推荐的 _wfopen_s: 它打开的文件不可共享，而这是 词库文件，Server、TSF DLL 和设置进程会并发读同一份。_SH_DENYNO 正是被弃用调用原本的共享语义，因此只消除警告，不改变行为。 _wsopen_s 的 pmode 传 0，唯一调用方 userdict.cpp 用的是 O_WRONLY， 不带 _O_CREAT。
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.
