.localizations ⇒ Object

all localizations are saved in this class variable localizations are namespaced using the language or locale they belong to

for instance:

ML10n.localizations['en'][:right] => 'right'
ML10n.localizations['en'][:left] => 'left'
ML10n.localizations['en']['US'][:greeting] => 'Howdie'
ML10n.localizations['en']['AU'][:greeting] => "Good'ay"

locales, including languages and countries use string keys while localization keys themselves are symbols

reset the localization dirs and files to the plugin config careful when using this method since it will remove any localization files you loaded after the plugin started

note that it won’t clear the localization already loaded in memory
