Kanpyo

Kanpyo is Japanese morphological analyzer written in Rust inspired by Kagome.

Caution

This is a work in progress. I would break the API without notice.

Installation

You can install kanpyo via cargo:

cargo install kanpyo

You need a dictionary to use kanpyo and can build and install a dictionary by the following.

cd kanpyo-dict
cargo run --release --bin ipa-dict-builder -- 

A dictionary is installed in the following directory:

• Linux
  • $HOME/.config/kanpyo/
• macOS
  • $HOME/Library/Application Support/kanpyo

You're ready to use kanpyo!
