i18n-tasks helps you find and manage missing and unused translations.

The gem analyses the code statically for key usages, such as I18n.t('a.key'), in order to:

• Report keys that are missing or unused.
• Pre-fill missing keys, optionally from Google Translate.
• Remove unused keys.

Thus addressing the two main problems of the i18n gem design:

• Missing keys only blow up at runtime.
• Keys no longer in use may accumulate and introduce overhead, without you knowing it.

This release (v0.9.4) adds support for reference keys, a much requested feature.
