Ruby-Locale

Ruby-Locale is the pure ruby library which provides basic and general purpose APIs for localization. It aims to support all environments which ruby works and all kind of programs (GUI, WWW, library, etc), and becomes the hub of other i18n/l10n libs/apps to handle major locale ID standards.

• Manage Locale ID(Language Tag)
  • Each thread has a Locale ID.
  • POSIX, CLDR, IETF(RFC4646, 3066(BCP47)), Win32 and Java language tags and convert the tag string to each other.
  • Auto detect Locale ID. POSIX(Unix/Linux/*BSD), Win32, JRuby, CGI.
• Resources
  • ISO 639-3 languages
  • ISO 3166 region(countries).
• Support Ruby 1.8.7, Ruby 1.9.1, JRuby 1.1.4. Tested on Win32 and Linux.
