== DESCRIPTION:
Text language detection. Quick, fast, memory efficient, and all in pure Ruby. Uses Bloom filters for aforementioned speed and memory benefits.
Works with Dutch, English, Farsi, French, German, Swedish, Portuguese, Russian and Spanish out of the box.
== FEATURES/PROBLEMS:
* It can be made far more efficient at the comparison stage, but all in good time..! It still beats literal dictionary approaches.
* No filter selection yet, you get 'em all loaded.
* Tests are reasonably light.
== SYNOPSIS:
Full Example
require 'whatlanguage'
texts = []
texts << %q{Deux autres personnes ont été arrêtées durant la nuit}
texts << %q{The links between the attempted car bombings in Glasgow and London are becoming clearer}
texts << %q{En estado de máxima alertaen su nivel de crítico}
texts << %q{Returns the object in enum with the maximum value.}
texts << %q{Propose des données au sujet de la langue espagnole.}
texts << %q{La palabra "mezquita" se usa en español para referirse a todo tipo de edificios dedicados.}
texts.each { |text| puts "#{text[0..18]}... is in #{text.language.to_s.capitalize}" }
Initialize WhatLanguage with all filters
wl = WhatLanguage.new(:all)
Return language with best score
wl.language(text)
Return hash with scores for all relevant languages
wl.process_text(text)
Convenience method on String
"This is a test".language # => "English"
