Translation plugin for Termtter

gistfile1.rb

# -*- coding: utf-8 -*-

# this plugin is detecting the language of a tweet and
# translate it to your language, if you can't understand
# the specific language
#
# configuration:
#   add to your .termtter/config some additional stuff
#   which language you prefer to read?
#     - config.mylang = 'en'
#   which languages should not be translated?
#     - config.readable_langs = ['en', 'de']
