EnchantDetect

Uses spell-checker dicitionary and check it against the words in the dictionary.

>>> enchanter = EnchantDetect()  # Higher score is better.

>>> enchanter.detect(fr_en_Latn)
('fr', 0.5824175824175823)

>>> enchanter.detect(fr_en_Latn, threshold=0.7, n_best=5)
[('un', 0.0)]

>>> enchanter.detect(fr_en_Latn, threshold=0.5, n_best=5)
[('fr', 0.5824175824175823),
 ('en', 0.49450549450549475),
 ('da', 0.23076923076923067),
 ('it', 0.17582417582417578),
 ('af', 0.17582417582417578)]

NgramDetect

Uses the ngram model from the original https://code.google.com/p/guess-language to detect the text's trigram distance from the ngram model.

>>> ngrammer = NgramDetect()  # Lowest score is better.

>>> ngrammer.detect(fr_en_Latn, n_best=10)
('fr', 68364)

>>> ngrammer.detect(fr_en_Latn, n_best=10)
[('fr', 68364),
('en', 70742),
('ca', 75113),
('la', 75319),
('it', 75917),
('pt', 76059),
('ro', 76652),
('es', 77139),
