Kradical

Utilities for working with the Electronic Dictionary Research and Development Group (EDRDG) radical decomposition files.

Usage

Converting EDRDG Files

The kradical_converter tool can convert EDRDG radical files to various formats. Use multiple --inputs flags to process multiple files together.

The JSON and UTF8 txt files are created under /assets/outputs/ with the below commands.

Create JSON

With output extension .json and json option:

# Generate krad.json
cargo run -p kradical_converter -- --inputs ./assets/edrdg_files/kradfile --inputs ./assets/edrdg_files/kradfile2 --output ./assets/outputs/krad.json krad json

# Generate radk.json
cargo run -p kradical_converter -- --inputs ./assets/edrdg_files/radkfile --inputs ./assets/edrdg_files/radkfile2 --output ./assets/outputs/radk.json radk json

Create UTF-8 txt

With output extension .txt and unicode option:

# Generate krad_utf8.txt (kanji → radicals mapping)
cargo run -p kradical_converter -- --inputs ./assets/edrdg_files/kradfile --inputs ./assets/edrdg_files/kradfile2 --output ./assets/outputs/krad_utf8.txt krad unicode

# Generate radk_utf8.txt (radical → kanji mapping)
cargo run -p kradical_converter -- --inputs ./assets/edrdg_files/radkfile --inputs ./assets/edrdg_files/radkfile2 --output ./assets/outputs/radk_utf8.txt radk unicode

Create Rust static files for kradical_static

With output extension .rs and rust option:

# Generate decompositions.rs (for kradical_static crate)
cargo run -p kradical_converter -- --inputs ./assets/edrdg_files/kradfile --inputs ./assets/edrdg_files/kradfile2 --output ./kradical_static/src/decompositions.rs krad rust

# Generate memberships.rs (for kradical_static crate)
cargo run -p kradical_converter -- --inputs ./assets/edrdg_files/radkfile --inputs ./assets/edrdg_files/radkfile2 --output ./kradical_static/src/memberships.rs radk rust

Executable usage

1. First, build the release version of the converter:

cargo build --release

2. Then replace cargo run -p kradical_converter -- --inputs with ./target/release/kradical_converter --inputs in the above commands.
   • On Windows also replace / with \ for the path.

• Static

Other

Included with this project under assets/outputs are several UTF-8-encoded variants of the source files in a more convenient format.

• krad_utf8.txt follows the same format as the original kradfile. Each line contains the following:
  • The kanji
  • A colon
  • Each of constituent radicals separated by spaces
• radk_utf8.txt differs from the original radkfile and instead mirrors the kradfile format. Each line contains the following:
  • The radical
  • The number of strokes in the radical
  • A colon
  • Each of the kanji that contain the radical separated by spaces
