fanlusky 837af70b7e fix(engine): 全拼云查询带上手动分词而非去边界的裸串
手动把 qi'e'huan 分成三段,云端却返回二段的「切换」。因为全拼云查询的 query_text
取自 normalized_input(已去掉撇号的裸串),云端拿不到音节边界只能自行贪心断句。改用
保留手动撇号的 normalized_segmentation 构造 query_text,与双拼分支一致;也让
to_google_spelling 能逐音节把 nve/lve 换成云端认的 nue/lue 写法。

Input engine (engine/)

中文 README · Website

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/, ngram/kenlm/, 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, ngram/kenlm (LGPL-2.1-or-later), utfcpp and voice/third_party/miniaudio keep their upstream licences.
