Overview

It’s a translator middleware which tries to identify a language of the passed word basing on :from_lang and :to_lang options. If it’s possible to explicitly identify a language and :from_lang and :to_lang options are required to be exchanged it exchanges them.

Example:

detector = LanguageDetector.new(translator)
detector.call("groß", :from_lang => :en, :to_lang => :de)
# It delegates call to translator like this:
#   translator.call("groß", :from_lang => :de, :to_lang => :en)
# Because in English there is no character "ß" but it exists in German.

NOTE: It doesn’t support Ruby 1.8
