# whatlanguage
by Peter Cooper
Text language detection. Quick, fast, memory efficient, and all in pure Ruby. Uses Bloom filters for aforementioned speed and memory benefits. It works well on texts of over 10 words in length (e.g. blog posts or comments) and *very poorly* on short or Twitter-esque text, so be aware.
Works with Dutch, English, Farsi, French, German, Italian, Pinyin, Swedish, Portuguese, Russian, Arabic, Finnish, Greek, Hebrew, Hungarian, Korean, Norwegian, Polish and Spanish out of the box.
## Important note
This library was first built in 2007 and has received only a few minor updates over the years. There are now more efficient and effective algorithms for doing language detection which I am investigating for a future WhatLanguage.
This library has been updated to be distributed and to work on modern Ruby implementations but other than that, has had no significant improvements.
## Synopsis
Full Example
```ruby
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 << %q{اللغة التي هي هذه؟}
texts << %q{Mitä kieltä tämä on?}
texts << %q{Ποια γλώσσα είναι αυτή;}
texts << %q{באיזו שפה זה?}
texts << %q{Milyen nyelv ez?}
texts << %q{이 어떤 언어인가?}
texts << %q{Hvilket språk er dette?}
texts << %q{W jakim języku to jest?}
texts.each { |text| puts "#{text[0..18]}... is in #{text.language.to_s.capitalize}" }
```
Initialize WhatLanguage with all filters
```ruby
wl = WhatLanguage.new(:all)
```
Return language with best score
```ruby
wl.language(text)
```
Return hash with scores for all relevant languages
```ruby
wl.process_text(text)
```
Convenience methods on String
```ruby
"This is a test".language # => :english
"This is a test".language_iso # => :en
```
Initialize WhatLanguage with certain languages
```ruby
wl = WhatLanguage.new(:english, :german, :french)
```
## Requirements
None, minor libraries (BloominSimple and BitField) included with this release.
## Installation
gem install whatlanguage
To test, go into irb, then:
```ruby
require 'whatlanguage'
"Je suis un homme".language
```
