Highlights

• First release of Sudachi.rs
• SudachiPy compatible Python bindings
• ~30x speed improvement over original SudachiPy
• Dictionary build mode will be done before 0.6.0 final (See #13)

Rust

• Analysis: feature parity with Python and Java version
• Dictionary build is not supported in rc1
• ~2x faster than Java version (with sentence splitting)
• No public API at the moment (contact us if you want to use Rust version directly, internals will significantly change and names are not finalized)

Python

• Mostly compatible with SudachiPy 0.5.4
• We provide binary wheels for popular platforms
• ~30x faster than 0.5.4
• IgnoreYomigana input text plugin is now supported (and enabled by default)
• We provide binary wheels for convenience (and additional speed on Linux)

Known Issues

• List of deprecated SudachiPy API:
  • MorphemeList.empty(dict: Dictionary)
    • This also needs a dictionary as an argument.
  • Morpheme.split(mode: SplitMode)
  • Morpheme.get_word_info()
  • Most of instance attributes are not exported: e.g. Dictionary.grammar, Dictionary.lexicon.
    • See API reference page for supported APIs.
• Dictionary Build is not supported: sudachipy build and sudachipy ubuild will not work, please use 0.5.3 in another virtual environment for the time being until the feature is implemented: #13
