# This is a basic backend for key value stores. It receives on
# initialization the store, which should respond to three methods:
#
# * store#[](key)         - Used to get a value
# * store#[]=(key, value) - Used to set a value
# * store#keys            - Used to get all keys
#
# Since these stores only supports string, all values are converted
# to JSON before being stored, allowing it to also store booleans,
# hashes and arrays. However, this store does not support Procs.
#
# As the ActiveRecord backend, Symbols are just supported when loading
# translations from the filesystem or through explicit store translations.
#
# Also, avoid calling I18n.available_locales since it's a somehow
# expensive operation in most stores.
#
# == Example
#
# To setup I18n to use TokyoCabinet in memory is quite straightforward:
#
#   require 'rufus/tokyo/cabinet' # gem install rufus-tokyo
#   I18n.backend = I18n::Backend::KeyValue.new(Rufus::Tokyo::Cabinet.new('*'))
#
# == Performance
#
# You may make this backend even faster by including the Memoize module.
# However, notice that you should properly clear the cache if you change
# values directly in the key-store.
#
# == Subtrees
#
# In most backends, you are allowed to retrieve part of a translation tree:
#
#   I18n.backend.store_translations :en, :foo => { :bar => :baz }
#   I18n.t "foo" #=> { :bar => :baz }
#
# This backend supports this feature by default, but it slows down the storage
# of new data considerably and makes hard to delete entries. That said, you are
# allowed to disable the storage of subtrees on initialization:
#
#   I18n::Backend::KeyValue.new(@store, false)
#
# This is useful if you are using a KeyValue backend chained to a Simple backend.

# Backend that lazy loads translations based on the current locale. This
# implementation avoids loading all translations up front. Instead, it only
# loads the translations that belong to the current locale. This offers a
# performance incentive in local development and test environments for
# applications with many translations for many different locales. It's
# particularly useful when the application only refers to a single locales'
# translations at a time (ex. A Rails workload).  The implementation
# identifies which translation files from the load path belong to the
# current locale by pattern matching against their path name.
#
# Specifically, a translation file is considered to belong to a locale if:
# a) the filename is in the I18n load path
# b) the filename ends in a supported extension (ie. .yml, .json, .po, .rb)
# c) the filename starts with the locale identifier
# d) the locale identifier and optional proceeding text is separated by an underscore, ie. "_".
#
# Examples:
# Valid files that will be selected by this backend:
#
# "files/locales/en_translation.yml" (Selected for locale "en")
# "files/locales/fr.po"  (Selected for locale "fr")
#
# Invalid files that won't be selected by this backend:
#
# "files/locales/translation-file"
# "files/locales/en-translation.unsupported"
# "files/locales/french/translation.yml"
# "files/locales/fr/translation.yml"
#
# The implementation uses this assumption to defer the loading of
# translation files until the current locale actually requires them.
#
# The backend has two working modes: lazy_load and eager_load.
#
# Note: This backend should only be enabled in test environments!
# When the mode is set to false, the backend behaves exactly like the
# Simple backend, with an additional check that the paths being loaded
# abide by the format. If paths can't be matched to the format, an error is raised.
#
# You can configure lazy loaded backends through the initializer or backends
# accessor:
#
#   # In test environments
#
#   I18n.backend = I18n::Backend::LazyLoadable.new(lazy_load: true)

  # rule and use it to pluralize the given entry. I.e., the library expects
  # pluralization rules to be stored at I18n.t(:'i18n.plural.rule')
  #
  # Pluralization rules are expected to respond to #call(count) and
  # return a pluralization key. Valid keys depend on the pluralization
  # rules for the locale, as defined in the CLDR.
  # As of v41, 6 locale-specific plural categories are defined:
  #   :few, :many, :one, :other, :two, :zero
  #
  # n.b., The :one plural category does not imply the number 1.
  # Instead, :one is a category for any number that behaves like 1 in
  # that locale. For example, in some locales, :one is used for numbers
  # that end in "1" (like 1, 21, 151) but that don't end in
  # 11 (like 11, 111, 10311).
  # Similar notes apply to the :two, and :zero plural categories.
  #
  # If you want to have different strings for the categories of count == 0
  # (e.g. "I don't have any cars") or count == 1 (e.g. "I have a single car")
  # use the explicit `"0"` and `"1"` keys.

  #
  # *LOOKUP*
  #
  # Translation data is organized as a nested hash using the upper-level keys
  # as namespaces. <em>E.g.</em>, ActionView ships with the translation:
  # <tt>:date => {:formats => {:short => "%b %d"}}</tt>.
  #
  # Translations can be looked up at any level of this hash using the key argument
  # and the scope option. <em>E.g.</em>, in this example <tt>I18n.t :date</tt>
  # returns the whole translations hash <tt>{:formats => {:short => "%b %d"}}</tt>.
  #
  # Key can be either a single key or a dot-separated key (both Strings and Symbols
  # work). <em>E.g.</em>, 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.
  #
  # <em>E.g.</em>, with a translation <tt>:foo => "foo %{bar}"</tt> 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 singular/plural versions of translations like <tt>['Foo', 'Foos']</tt>.
  #
  # Note that <tt>I18n::Backend::Simple</tt> 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 <tt>:count</tt> option can be used both for pluralization and interpolation.
  # <em>E.g.</em>, with the translation
  # <tt>:foo => ['%{count} foo', '%{count} foos']</tt>, count will
  # be interpolated to the pluralized translation:
  #   I18n.t :foo, :count => 1 # => '1 foo'
  #
  # *DEFAULTS*
  #
  # This returns the translation for <tt>:foo</tt> or <tt>default</tt> if no translation was found:
  #   I18n.t :foo, :default => 'default'
  #
  # This returns the translation for <tt>:foo</tt> or the translation for <tt>:bar</tt> if no
  # translation for <tt>:foo</tt> was found:
  #   I18n.t :foo, :default => :bar
  #
  # Returns the translation for <tt>:foo</tt> or the translation for <tt>:bar</tt>
  # or <tt>default</tt> if no translations for <tt>:foo</tt> and <tt>:bar</tt> were found.
  #   I18n.t :foo, :default => [:bar, 'default']
  #
  # <b>BULK LOOKUP</b>
  #
  # This returns an array with the translations for <tt>:foo</tt> and <tt>:bar</tt>.
  #   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
  #
  # *LAMBDAS*
  #
  # Both translations and defaults can be given as Ruby lambdas. Lambdas will be
  # called and passed the key and options.
  #
  # E.g. assuming the key <tt>:salutation</tt> resolves to:
  #   lambda { |key, options| options[:gender] == 'm' ? "Mr. #{options[:name]}" : "Mrs. #{options[:name]}" }
  #
  # Then <tt>I18n.t(:salutation, :gender => 'w', :name => 'Smith')</tt> will result in "Mrs. Smith".
  #
  # Note that the string returned by lambda will go through string interpolation too,
  # so the following lambda would give the same result:
  #   lambda { |key, options| options[:gender] == 'm' ? "Mr. %{name}" : "Mrs. %{name}" }
  #
  # It is recommended to use/implement lambdas in an "idempotent" way. E.g. when
  # a cache layer is put in front of I18n.translate it will generate a cache key
  # from the argument values passed to #translate. Therefore your lambdas should
  # always return the same translations/values per unique combination of argument
  # values.
  #
