Thread:Talk:ResourceLoader/Version 2 Design Specification/Gadget developers/reply (4)

Previously gadgets had no support for localization. For Gadgets 2.0 we're providing all ResourceLoader features for localization.

As for anything related to localization and interface messages, these are restricted to users with the 'editinterface' right. Depending on your wiki configuration this right could be given to groups like "translators" or "interface editors" or "administrators" (default).

Interface messages are intentionally not covered by the "gadgets-edit" right, that's exactly the point of separating these away from interface editors so that gadgets become more accessible.

Due to translations/localization being completely native, fallbacks to other languages and availability in  comes along for free.

The Gadgets "Export"/"Import" feature also covers messages in the MediaWiki:-namespace, so if a gadget is developed somewhere and imported by an admin, those will be imported as well.
