module Alchemy
module I18n
# Alchemy translation methods
#
# Instead of having to translate strings and defining a default value:
#
# Alchemy::I18n.t("Hello World!", :default => 'Hello World!')
#
# We define this method to define the value only once:
#
# Alchemy::I18n.t("Hello World!")
#
# Note that interpolation still works:
#
# Alchemy::I18n.t("Hello %{world}!", :world => @world)
#
# It offers a shortcut method and view helper called _t
#
# === Notes
#
# All translations are scoped into the +alchemy+ namespace.
# Even scopes are scoped into the +alchemy+ namespace.
#
# So a call for _t('hello', :scope => :world) has to be translated like this:
#
# de:
# alchemy:
# world:
# hello: Hallo
