The Localizer filter brings localization to your mustache templates:

let template = ...
template.register(StandardLibrary.Localizer(), forKey: "localize")

It can localize:

• variables: {{ localize(greeting) }} renders the localization of the greeting variable
• template snippets: {{# localize }}Hello{{/ localize }} renders the localization of "Hello"
• embedded variables: {{# localize }}Hello {{name}}{{/ localize }} localizes "Hello %@", and uses the result at a format string in which in injects the rendering of the name variable

As it is today, Localizer uses NSLocalizedString. Two areas of improvements are:

• Make Localizer extensible so that it can be fueled by another localization engine than NSLocalizedString
• Make it use a custom locale

@groue Until now we did not receive any localization requirements, so I have no opinion on this topic.
