Ember CLI i18n
Deprecated!
This library has been deprecated in favor of ember-i18n >= 4.0.0
About
Simple Internationalization support for ember-cli apps.
Note: This release requires Ember 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:
Computed properties for the path are also supported:
If the value has interpolation keys you can pass those values:
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'])
Overriding the Locale Lookup Handler
By default locales are attempted to be looked as modules in your project. However, you may wish to override how this is done. You can do that by overriding the locale lookup handler. Let's assume you have all of your locales stored in a single POJO.
You'll first need to create a new file: my-app/services/i18n.js
import service from 'ember-cli-i18n/services/i18n';
service.getLocalizedPath = function(locale, path) {
return Locales[locale][path];
}
export default service;
The default service object that was imported has three functions that can be overridden and customized:
resolveLocale
- Paramaters:
container
,scope
- Returns: locale code
getLocalizedPath
- Paramaters:
locale
,path
,container
,scope
- Returns: string or object
applyPluralizationRules
- Paramaters:
result
,locale
,path
,container
,values
,scope
- Returns: if
result
is a string, will skip rules and returnresult
. Ifresult
is anObject
, will assume pluralization needs to apply and formatsresult
with proper pluralization rules based uponvalues[0]
fmt
- Paramaters:
result
,values
- Returns: formatted string
This function delegates to Ember.String.fmt
by default. You can override
