Ruby gem to translate a string from one language to another using Google’s public translate endpoint (https://translate.googleapis.com/translate_a/single). The integration does not require an API key.
gem install language-translator
require 'rubygems' require 'translator' tr = Translator.new # translate from English to Hindi tr.translate('Hello, World', 'hi', 'en') #=> "नमस्ते, दुनिया" # translate from Japanese to English tr.translate('こんにちは世界', 'en', 'ja') #=> "Hello world" # let Google auto-detect the source language (to English) tr.to_en('¡Hola, mundo!') #=> "Hello world"
All HTTP calls are mocked via Mocha. You can run the suite without network access:
ruby -Itest test/translator_test.rb
To experiment interactively without installing the gem:
irb -I lib
irb(main):001:0> require 'translator'
=> true
irb(main):002:0> Translator.new.translate('Hello world', 'es', 'en')
=> "Hola Mundo"
Translator::SUPPORTED_LANG_CODES tracks every language code currently available through Google Translate (including legacy aliases like iw and pt-PT). Call Translator::SUPPORTED_LANG_CODES.sort if you need to inspect or display the full list.
