符号数据改用 rime-wanxiang 的符号表与 typst/codex 符号名，源数据放在 msime-dictionary 的 sources/symbols/，替换原来的 piliapp 符号表。 - 建库：新增 symbols_db.py，生成表情面板用的 symbol_catalog（中文分类）和 S 模式、符号混输用的 symbol_code；剔除 wanxiang-unrenderable.txt 列出的 Windows 自带字体显示不了的符号，以及与 ① ❶ 看不出区别的 Dingbats 带圈数字 - 新增 scripts/check-symbol-rendering.py，用 Windows 字体生成上面的剔除清单 - Shift+S 进入符号模式，按万象分组码（xl、sx、szq）、数字读音（yi → 一 ① ⑴） 或符号名（alpha、infinity）检索 - 符号混输：整串精确等于编码时混入，首个紧跟首选；读得成拼音的编码只混数字 序号写法；双拼先按方案换算成全拼再查（小鹤 sj → san → ③） - 表情面板符号页：中文分类，搜索把整词命中的符号列在「最佳匹配」 - 配置：utility.symbol_mode（默认开）、general.symbol_mixed_input（默认关） Refs #795
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 settings-window 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 settings-window 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.
