Ember CLI i18n

About

Simple Internationalization support for ember-cli apps.

Note: This release requires Ember 1.9. Will likely break with 1.10

Install

npm install ember-cli-i18n --save-dev

Usage

Translate

Configuration

In your app's config/environment.js you'll need to set ENV.APP.defaultLocale to a country code:

var ENV = {
  APP: {
    defaultLocale: 'en'
  }
};

defaultLocale is only the fallback. If you wanted to change the locale of the application you should modify your application's locale:

var set = Ember.set;
var application = container.lookup('application:main');
set(application, 'locale', 'fr');

You can can trigger this after authentication, or if the user modifies a language setting in the app. Of course when this state is removed you should clear locale so that internationalization fallback to defaultLocale.

Locale Files

Generate a new locale file:

ember g locale en

The file will be added to app/locales

app
└── locales
    └── en.js

Then export a single POJO:

export default {
  home: {
    title: 'Welcome'
  }
};

Interpolation

You can add keys for interpolation

export default {
  age: 'You are %@1 years old.',
  name: '%@, %@'
};

The rules for interpolation follow the same from Ember.String.fmt

Pluralization

Pluralization keys follow the format from CLDR. For example, for en it expects only the keys one and other:

export default {
  friend: {
    one: 'only one friend, %@2',
    other: '%@ friends, %@'
  }
};

The first value passed will be considered the count for determining how to pluralize.

t('friend', 0, 'Brian');
// 0 friends, Brian

t('friend', 1, 'Brian');
// only one friend, Brian

t('friend', 10, 'Brian');
// 10 friends, Brian

Hyphenated languages will be split and the first half will be used to determine the pluralization rules. So both en-us and en-gb will follow the en rules.

View the currently supported set of pluralization rules.

Helper

You can access the translations in your app with the t helper:

{{t 'home.title'}}

Computed properties for the path are also supported:

{{t age}}

If the value has interpolation keys you can pass those values:

{{t colors colorOne colorTwo}}

Utility

The t function can be used outside of templates as a utility function:

import Ember from 'ember';

export default Ember.Object.extend({
  foo: function() {
    var t = container.lookup('utils:t');
    return t('foo.bar');
  }
});

t is automatically injected into Controllers, Components, Routes, and Models:

export default DS.Model.extend({
  name: function() {
    return this.t('name', 'John', 'Doe');
  }
});

Note that interpolation values can also be passed as an array if you prefer this style. this.t('name', ['John', 'Doe'])
