i18n-bamboo

https://github.com/tcdowney/i18n-bamboo

Consider the noble bamboo. This peculiar member of the Poaceae family has been known to grow to extraordinary lengths without yielding to (mostly) any obstacles. Not unlike bamboo, the i18n translations of a Rails app will continue to grow. As a tenacious stalk of bamboo breaks through a slab of sidewalk, so too will long translations break a UI. I18n:Bamboo monkey patches the Rails I18n module and will force all calls to I18n.translate (I18n.t) and I18n.localize (I18n.l) to return the longest translated or localized value from all available_locales. For obvious reasons, this gem is intended to be used for development purposes only to aid in UI and internationalization/localization testing.
