* feat(engine,server,windows,ui-html,installer): U 模式重构为部件拆字反查 (#971) 把 U 模式从 Unicode 十六进制码位输入改成部件拆字反查：Shift+U 后输入各 组成部分的拼音连写（晶 = ririri）即可出字，候选上反显注音。 - 引擎：新增 local_modes/radical_query（前缀匹配、字频降序），数据表 engine/radical/decomposition.txt 与生成脚本；LocalInputMode::Unicode 改为 Radical；删除 unicode_query。 - Server：g_radical_mode_triggered + IsRadicalCompositionActive + 候选分发， 用 cpp-pinyin 反显注音；删除 Unicode 码位路径。 - 前端 TSF：删除 U 模式的十六进制/数字特例与影子预判，按普通组合处理。 - 配置：utility.unicode_mode 改为 utility.radical_mode。 - 部署：assets 登记 radical_decomposition，安装器与 CI 拷表。 数据来源 mirtlecn/rime-radical-pinyin (GPL-3.0)，授权见 engine/radical/NOTICE.md。 * feat(server): U 模式反显拼音改为带调风格（jīng） * fix(server,installer): 修复 U 模式 CI（拆字表打包夹具与 clang-format） * fix(engine,server): 修正 U 模式按键错位、重复候选与配置迁移 - Server 在 U 模式不再吞掉撇号、分号、斜杠、大写字母等键：TSF 已把它们记进按键缓冲， 吞掉又不重同步会让两侧串和光标错位。照常插入，含非 a-z 的码查不出候选 - 拆字查询全码命中排在仅前缀命中之前，同一个字的几种拆法只出一次 - 升级合并把旧键 utility.unicode_mode 的值带到 utility.radical_mode，读取时也兜底旧键 - 生成脚本只收汉字，重建拆字表去掉 abc 码下的 51 行数字、字母与符号 - 开着 U 模式时在后台预热拆字表与 cpp-pinyin 词典，避开首个按键的冷加载 - Server 按会话的 RuntimePaths 查拆字表，删掉走全局数据目录的便捷重载 - cpp-pinyin 初始化合并到 utils/hanzi_pinyin，设置页导入注音共用；U 模式与快捷短语的收键分支合并 --------- Co-authored-by: fanlusky <1730976608@qq.com>
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/, 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.
