angular-gettext - gettext utilities for angular.js

Translate your Angular.JS applications with gettext.

Getting started

Add angular-gettext to your project:

1. Grab the files, either by copying the files from the dist folder or (preferably) through bower: bower install --save angular-gettext.

2. Include the angular-gettext source files in your app:

   <script src="bower_components/angular-gettext/dist/angular-gettext.min.js"></script>
   

3. Add a dependency to angular-gettext in your Angular app:

   angular.module('myApp', ['gettext']);
   

You can now start using the translate directive to mark strings as translatable.

Next steps:

• Annotate strings with the translate directive.
• Extract strings from the source code.
• Translate strings
• Integrate translated strings back into the application.
• Set the correct language for translations.

Using the translate directive

Strings are marked as translatable using the translate directive. Here's a simple example:

 <h1 translate>Hello!</h1>

This div will automatically be translated using the translated strings (which we'll define later on). For instance, in Dutch, it might read Hallo!.

Plurals

Plural strings can be annotated using two extra attributes: translate-n and translate-plural:

 <div translate translate-n="count" translate-plural="{{count}} boats">One boat</div>

The general format is:

 <div translate translate-n="COUNTEXPR" translate-plural="PLURALSTR">SINGULARSTR</div>

Depending on the value of COUNTEXPR, either the singular string or the plural string will be selected.

Interpolation

Full interpolation support is available in translated strings, so the following will work as expected:

 <div translate>Hello {{name}}!</div>

Extracting strings

Use grunt-angular-gettext to extract strings from your HTML templates into a .pot catalog.

Translate strings

Use a tool like poedit, Pootle or Transifex to translate the strings.

Setting translated strings

You can set translated strings by injecting the gettextCatalog and using the setStrings method.

As an example, you may have the following code in your application:

angular.module('myApp').run(function (gettextCatalog) {
    // Load the strings automatically during initialization.
    gettextCatalog.setStrings('nl', {
        'Hello': 'Hallo',
        'One boat': ['Een boot', '{{count}} boats']
    });
});

Converting translated .po files into angular-compatible JavaScript files can be done automatically using the grunt-angular-gettext module.

Setting the language

Set the language by setting a language code on the catalog:

angular.module('myApp').run(function (gettextCatalog) {
    gettextCatalog.currentLanguage = 'nl';
});

You can do this anywhere in your application, the use of a run block above is just an example.

Contributing

All code lives in the src folder and is written in CoffeeScript. Try to stick to the style conventions used in existing code.

Tests can be run using grunt test. A convenience command to automatically run the tests is also available: grunt watch. Please add test cases when adding new functionality: this will prove that it works and ensure that it will keep working in the future.
