* feat(engine,server): 五笔支持 T 模式与 V 模式 五笔方案此前被排除在 Shift+T 日期时间模式与 V 模式之外。根因是方案层就把 raw 归一成小写 a–y、丢弃数字与运算符，Server 的形状判定读不到大写 T/V 前缀。 - 引擎 WubiScheme 新增 raw_input_with_cases_：保留大小写与 T/V 模式的非字母键 （数字、运算符、: /），但按码字域丢掉越域字母（默认配置下 z）。查询码仍由 normalize_wubi_code 派生，普通码下两者长度相等——Server 用原样串长度数四码。 - Server：T 触发新增独立谓词 date_time_scheme（chinese_scheme || Wubi），不并入 chinese_scheme 本身；FormatVModeWorkerPayload 对五笔返回 UppercaseOnly。 - 自动上屏 / 顶字两个谓词新增 special_mode_active 前置：T 模式关键词归一后可能与 合法四码重合（Tdate → tdat），不挡会在第四个字母上结束模式。 - 引擎与 Server 测试、README 与两份配置模板文案同步。 * fix(engine,server,ui-html): 五笔 T/V 模式由宿主标注字面输入 原实现让五笔原样串不再裁到码长，普通码下原样串可以比码长（混输关、z 通配时 wqazb 对 wqaz）， Server 读回后光标、退格和上屏都会错位；守卫也只认 T 模式的全小写主体，TdatE 仍会顶出 tdat。 - 引擎：InputSession::set_wubi_literal_input 随 pending 序列一起下发，只作用于同一次设置。 普通码的原样串就是带大小写的码，与查询码逐位对应、一起截断；字面输入原样保留， 不查码表与拼音，也不算完整四码。退格从原样串重新派生码，字母键两份视图取同一个字母。 - Server：ApplyCompositionEditKey 按 IsWubiLiteralComposition（T 模式触发标记或 V 模式形状） 标注字面输入；两个五笔上屏策略恢复原签名，不再需要 special_mode_active。 - 设置页 T/V 模式说明补上五笔。 --------- 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.
