fanlusky 42fbb9541c feat(engine): 快捷短语混入全拼 / 双拼候选并参与调频
Shift+K 快捷短语模式保留,仍按编码前缀查询(query_quick_phrases)。另外全拼 / 双拼下
编码精确匹配(query_quick_phrases_by_code)的快捷短语作为一组插在固定位置候选之后,由
LocalModeOptions::quick_phrase_candidates 单独开关;五笔不混。

用户日志新增 quick_phrase_slots 表记录快捷短语组前的普通候选数:选中短语让组前移,
越过组选普通候选让组后移,后移上限为页长减一。quick_phrase_frequency 关掉时组固定在
首位。与普通候选同文本时保留快捷短语那份。

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.
