Module: I18n

Public Instance Methods

candidates (type = :common)

Get the locale candidates as a Locale::TagList. This is the utility function which calls Locale.candidates with supported_language_tags.

I18n.locale is also overrided by Ruby-Locale and it returns the result of this method with :rfc option.

type :simple, :common(default), :rfc, :cldr.

This is used by Rails application, but it may be better not to use this method in Rails plugins/libraries, because they have their own supported languages.
