Ember TML

This addon adds helpers for doing advanced localization of your ember apps with Translation Markup Language (TML) by Translation Exchange.

Translation Markup Language (TML) is a simple markup language that provides syntax for identifying dynamic data and decorations within strings. TML aims at abstracting out the decoration mechanisms of the string and instead provides its own simple, but powerful syntax. This allows for translation sharing across multiple applications and platforms.

Installation

ember install ember-tml

Configuration

The first thing you need to do to get started with Ember TML is sign up for a free Translation Exchange account and create your first project.

Once you have created a project and have your project key and token you must configure the service:

// config/environment.js
module.exports = function(environment) {
  var ENV = {
    tml: {
      key: "YOUR_PROJECT_KEY"
    }
  }
}

Usage

Initializing the SDK

To start using tml in your templates you will need to initialize the SDK. We suggest doing it in the beforeModel hook of your application route.

This will retrieve any translations from either your cache or the CDN before rendering any templates.

// app/routes/application.js
export default Ember.Route.extend({
  beforeModel(){
    return this.get('tml').initialize();
  }
});

Helpers

The Ember TML Addon provides a few helpers and a service:

{{tr}} Helper

tr is the basic translate function. It takes 3 parameters:

• label is the only required parameter.
• description is an optional parameter, but should always be used if the label by itself is not sufficient enough to provide the meaning of the phrase.
• tokens is an optional parameter that contains a hash of token values to be substituted in the label.

This is what it should look like in your templates:

<div>{{tr "Hello World" }}</div>
<div>{{tr "Invite" "Link to invite your friends"}}</div>
<div>{{tr "Welcome {user}!" user=userName}}</div>
<div>{{tr "You have {count || message, messages}" count=1}}</div>
<div>{{tr "You have {count || message, messages}" count=5}}</div>

yields:

<div>Hello World</div>
<div>Invite</div>
<div>Welcome Jane!</div>
<div>You have 1 message</div>
<div>You have 5 messages</div>

{{trl}} Helper

trl works the same as tr but should be used for attribute values.

<img src="..." title={{trl "Hello World"}} />
{{input placeholder=(trl "Enter email address")}}

yields:

<img src="..." title="Hello World" />
<input placeholder="Enter email address" />

API

TML Service Api

The TML service will be injected into Controllers, Routes, Views and Components.

Ember.get(this, 'tml').trl("Hello World");

and includes some handy methods for working with TML:

currentTranslator
an object representing the current logged in translator

Ember.get(this, 'tml.currentTranslator');
// {
//   name: "translator_username",
//   inline: true
// }

currentSource
a string of the current source

Ember.get(this, 'tml.currentSource');
// "index"

currentApplication
return an object representing your Translation Exchange application

Ember.get(this, 'tml.currentApplication');
// {
//   id: 123,
//   key: "APP_KEY",
//   name: "Dom Examples",
//   current_locale: "zh",
//   default_locale: "en-US",
//   features: {...},
//   languages: [...]
// }

currentLanguage
returns the currently selected language

Ember.get(this, 'tml.currentLanguage');
// {
//   id: 233,
//   english_name: "Russian",
//   native_name: "Русский",
//   locale: "ru",
//   right_to_left: false,
//   flag_url: "https://s3-us-west-1.amazonaws.com/trex-snapshots/flags/default/languages/16/ru.png"
// }

availableLanguages
returns a list of all available languages for your project

translationModeEnabled
returns whether or not the application is currently in translation mode

translate(label [,description, tokens])
tr(label [,description, tokens])
works the same as the tr helper

translateLabel(label [,description, tokens])
trl(label [,description, tokens])
works the same as the trl helper

changeLanguage(locale)
sets the current language

Building a Language Selector

<ul>
  {{#each tml.availableLanguages as |language|}}
    <li>
      <a {{action (action tml.changeLanguage) language.locale}}>
        <img src={{language.flag_url}} />
        {{tr language.english_name}}
      </a>
    </li>
  {{/each}}
</ul>
