Useful ruby scripts for the JQuiz application.

Get vocabulary lists from webpages on the Internet!

The web page https://japanesetest4you.com/ is a very nice web page with a lot of information for mastering Japanese.
However, learning vocabulary from a web page can be tedious and inefficient.
The scripts in this folder allow you to get the vocabulary from a web page and practicing it using the Jquiz application.

At the same time, these scripts demonstrate how easy is to use the nokogiri tool for extracting data on a web page.

breen_extractor.rb <file with words in kanji>
-----------------------------------------------------------------------------------
Creates a vocabulary list from a list of words in kanji.

Let's suppose that you have a list of words in kanji and you want to learn their meaning and pronunciation.
With this script, you will get a vocabulary list ready to be used with Jquiz!

The words in the input list should be separated by a new line.
Like this:

契約
当社
不利
不満
不平
不安

This script uses Jim Breen's WWWJDIC to get the meaning and the furigana.
