- # Translates, pluralizes and interpolates a given key using a given locale,

- #
- # *LOOKUP*
- #
- # Translation data is organized as a nested hash using the upper-level keys
- # as namespaces. E.g., ActionView ships with the translation:
- # :date => {:formats => {:short => "%b %d"}}.
- #
- # Translations can be looked up at any level of this hash using the key argument
- # and the scope option. E.g., in this example I18n.t :date
- # returns the whole translations hash {:formats => {:short => "%b %d"}}.
- #
- # Key can be either a single key or a dot-separated key (both Strings and Symbols
- # work). E.g., the short format can be looked up using both:
- # I18n.t 'date.formats.short'
- # I18n.t :'date.formats.short'
- #
- # Scope can be either a single key, a dot-separated key or an array of keys
- # or dot-separated keys. Keys and scopes can be combined freely. So these
- # examples will all look up the same short date format:
- # I18n.t 'date.formats.short'
- # I18n.t 'formats.short', :scope => 'date'
- # I18n.t 'short', :scope => 'date.formats'
- # I18n.t 'short', :scope => %w(date formats)
- #
- # *INTERPOLATION*
- #
- # Translations can contain interpolation variables which will be replaced by
- # values passed to #translate as part of the options hash, with the keys matching
- # the interpolation variable names.
- #
- # E.g., with a translation :foo => "foo {{bar}}" the option
- # value for the key +bar+ will be interpolated into the translation:
- # I18n.t :foo, :bar => 'baz' # => 'foo baz'
- #
- # *PLURALIZATION*
- #
- # Translation data can contain pluralized translations. Pluralized translations
- # are arrays of singluar/plural versions of translations like ['Foo', 'Foos'].
- #
- # Note that I18n::Backend::Simple only supports an algorithm for English
- # pluralization rules. Other algorithms can be supported by custom backends.
- #
- # This returns the singular version of a pluralized translation:
- # I18n.t :foo, :count => 1 # => 'Foo'
- #
- # These both return the plural version of a pluralized translation:
- # I18n.t :foo, :count => 0 # => 'Foos'
- # I18n.t :foo, :count => 2 # => 'Foos'
- #
- # The :count option can be used both for pluralization and interpolation.
- # E.g., with the translation
- # :foo => ['{{count}} foo', '{{count}} foos'], count will
- # be interpolated to the pluralized translation:
- # I18n.t :foo, :count => 1 # => '1 foo'
- #
- # *DEFAULTS*
- #
- # This returns the translation for :foo or default if no translation was found:
- # I18n.t :foo, :default => 'default'
- #
- # This returns the translation for :foo or the translation for :bar if no
- # translation for :foo was found:
- # I18n.t :foo, :default => :bar
- #
- # Returns the translation for :foo or the translation for :bar
- # or default if no translations for :foo and :bar were found.
- # I18n.t :foo, :default => [:bar, 'default']
- #
- # BULK LOOKUP
- #
- # This returns an array with the translations for :foo and :bar.
- # I18n.t [:foo, :bar]
- #
- # Can be used with dot-separated nested keys:
- # I18n.t [:'baz.foo', :'baz.bar']
- #
- # Which is the same as using a scope option:
- # I18n.t [:foo, :bar], :scope => :baz
