Goal

Generate Sqlite relational databases from the JMDICT japanese dictionary.

setup

Dart SDK

SQL is generated using scripts written in dart;

Dart packages

Download required packages with

`pub get`

Utils required binaries

bash scripts are in the src directory to download dictionaries with wget and uncompressed them with gunzip.

Generate .db

sqlite3 db files are created and populated using the sqlite3 binary.

sudo apt install sqlite3

run.bash

Bash scripts src/run.bash can be called with arguments

bash run.bash <kanji|expression|help> [arguments]
arguments:
--download         download JMdict (expression) or kanjidic2 (kanji)
--sql [languages]  generate sql from downloaded dictionary.
--init             create db file tables
--populate         populate db file from generated sql
--clean [what]     delete db and/or sql file

Example: Reset previously generated expression database, generate sql for english sense and populate the db:

bash src/run.bash expression --clean --init --sql "eng" --populate

bash src/run.bash kanji --clean --init --sql "en" --populate

Generate sql for selected languages

The src/create_sql_expression.dart and src/create_sql_kanji.dart scripts can be called with arguments to process only some languages.

The languages are in ISO 639-3 format for expression and ISO 639-2 for kanji, for example:

English and French

dart src/expression/create_sql.dart eng fre

English only

dart src/expression/create_sql.dart eng

dart src/kanji/create_sql.dart en

note: run.bash allow to pass language arguments with quotes, for example:

bash src/run.bash expression --sql "eng fre"
