Changelog

Information

Documentation on the Microsoft Translator API is here

bing_translator is also smart about requesting the token, and handles this behind the scenes. It will only request a token if it knows the old one expired (X seconds from when we requested the last token, where X is given to us when we make the request. As of this writing, X is consistently 8 minutes).

Getting a free Azure account

To be able to use the API freely, do the following:

  1. Go here
  2. Sign in with valid Live credentials.
  3. Add the resource 'Cognitive Services APIs'
  4. In 'RESOURCE MANAGEMENT > Keys' pick either 'KEY 1' or 'KEY 2'

Usage

require 'rubygems'
require 'bing_translator'

translator = BingTranslator.new('COGNITIVE_SUBSCRIPTION_KEY')

# Translation

spanish = translator.translate('Hello. This will be translated!', :from => 'en', :to => 'es')
spanish = translator.translate('Hello. This will be translated!', :to => 'es')

# HTML Translations
spanish_html = translator.translate('<b>Hello</b>', to: 'es', textType: 'html')

# Translation of multiple strings

result = translator.translate_array(['Hello. This will be translated!', 'This will be translated too!'], :from => :en, :to => :fr)

# Translation of multiple strings, with word alignment information

result = translator.translate_array2(['Hello. This will be translated!', 'This will be translated too!'], :from => :en, :to => :fr)

# Language Detection

locale = translator.detect('Hello. This will be translated!') # => :en

Migration to API V3

Since version 6.0.0, this gem uses Microsoft Cognitive Translation Services in version 3.

Microsoft is dropping the support of Cognitive Translation Services Version 2 in April 2019. If you want to continue using this gem, migrate to 6.0.0.

I did my best to keep the backward compatibility with the previous gem version, but there are some breaking changes:

  • I dropped the support for the #speak method. If you need it, please create a GitHub issue, and I'll consider supporting it too.
  • I changed the interface for HTML translations. See the documentation above.
  • In the API v3, Microsoft does not allow translation of texts longer than 5000 characters.
