Get available locales from the translations hash
# File lib/i18n/backend/simple.rb, line 37 def available_locales init_translations unless initialized? translations.inject([]) do |locales, (locale, data)| locales << locale unless (data.keys - [:i18n]).empty? locales end end
# File lib/i18n/backend/simple.rb, line 21 def initialized? @initialized ||= false end
Clean up translations hash and set initialized to false on reload!
# File lib/i18n/backend/simple.rb, line 46 def reload! @initialized = false @translations = nil super end
Stores translations for the given locale in memory. This uses a deep merge for the translations hash, so existing translations will be overwritten by new ones only at the deepest level of the hash.
# File lib/i18n/backend/simple.rb, line 29 def store_translations(locale, data, options = {}) locale = locale.to_sym translations[locale] ||= {} data = data.deep_symbolize_keys translations[locale].deep_merge!(data) end
# File lib/i18n/backend/simple.rb, line 54 def init_translations load_translations @initialized = true end
Looks up a translation from the translations hash. Returns nil if eiher key is nil, or locale, scope or key do not exist as a key in the nested translations hash. Splits keys or scopes containing dots into multiple keys, i.e. currency.format is regarded the same as %w(currency format).
# File lib/i18n/backend/simple.rb, line 68 def lookup(locale, key, scope = [], options = {}) init_translations unless initialized? keys = I18n.normalize_keys(locale, key, scope, options[:separator]) keys.inject(translations) do |result, _key| _key = _key.to_sym return nil unless result.is_a?(Hash) && result.has_key?(_key) result = result[_key] result = resolve(locale, _key, result, options.merge(:scope => nil)) if result.is_a?(Symbol) result end end
