L20n/Firefox

Description

Gecko's current localization framework hasn't changed in the last two decades. It is based on file formats which weren't designed for localization. It offers crude APIs. It tasks developers with things they shouldn't have to do. It doesn't allow localizers to use the full expressive power of their languages.

L20n is a modern localization and internationalization infrastructure created by the Localization Engineering team in order to overcome these limitations. It was successfully used in Firefox OS. We've put parts of it on the ECMA standardization path. Now we intend to integrate it into Gecko and migrate Firefox to it.

Sprint 1: July 19 — July 25

This sprint is about setting the stage. We get a twig which is an semi-official branch in mozilla-central (and gecko-projects in git) with integration tests enabled. We collaborate on the twig going forward. Once one of the future sprint's deliverables is ready to land on mozilla-central we follow the regular process: bug, patch, push to try, landing by a sheriff. We then merge mozilla-central into the twig. Rinse and repeat until everything has landed on mozilla-central.
