This is MZ-IME Japanese Input (mzimeja). This program is a Japanese Input Method Editor (IME) for Windows.
For non-Japanese keyboards (e.g., US, German layouts), you can toggle the IME ON/OFF using Alt+~ (Alt+VK_OEM_3).
MZ-IMEja supports the high-performance morphological analysis engine Vibrato for faster and more accurate kana-kanji conversion.
Note: The following performance improvements are estimated targets based on Vibrato's capabilities. Actual performance will be measured once the full implementation is complete.
- 3x faster conversion compared to the legacy engine (target)
- Improved accuracy through better morphological analysis (target)
- Compact dictionary using Vibrato's efficient storage format (target)
- License: MIT / Apache 2.0 (compatible with GPLv3)
- Rust 1.70 or later
- Cargo
# Install Rust (if not already installed)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Convert dictionary (optional - requires Vibrato tools)
bash tools/convert_mecab_dict.sh
# Build with Vibrato support
mkdir build && cd build
cmake .. -DUSE_VIBRATO=ON
cmake --build .mkdir build && cd build
cmake .. -DUSE_VIBRATO=OFF
cmake --build .| Engine | Speed | Memory | Dictionary Size |
|---|---|---|---|
| Legacy | 1.0x (baseline) | ~30MB | ~15MB |
| Vibrato | 3.0x (target) | ~15MB (target) | ~7.5MB (target) |
Note: Performance numbers are estimated targets and will be validated once the implementation is complete.
When Vibrato is enabled but not available (e.g., dictionary not found), MZ-IMEja automatically falls back to the legacy conversion engine. This ensures the IME continues to function even if Vibrato initialization fails.
- MZ-IMEja: GPLv3
