Attempts to determine the natural language of a selection of Unicode (utf-8) text.
Based on guesslanguage.cpp by Jacob R Rideout for KDE which itself is based on Language::Guess by Maciej Ceglowski. Original repo is at Google Code; repackaged with package metadata here.
Detects over 60 languages; Greek (el), Korean (ko), Japanese (ja), Chinese (zh) and all the languages listed in the trigrams directory.
I recommend using Pip:
$ pip install -e 'git://github.com/dsc/guess-language.git#egg=guess-language'
If you prefer easy_install:
$ git clone git://github.com/dsc/guess-language.git
$ easy_install guess-language
The old-school way also works:
$ git clone git://github.com/dsc/guess-language.git
$ cd guess-language
$ python setup.py install
