Curious of seeing if I could use a Cocoa framework to detect the language of a string, I ended up finding a surprisingly clean and easy solution.
I decided to post my findings online since I couldn't find anything when I googled the topic:

In less than 10LOC, here is how to implement this feature:


framework 'Foundation'
class String


  def language
    CFStringTokenizerCopyBestStringLanguage(self, CFRangeMake(0, self.size))


  end
end

"bonne année!".language # => "fr"
