dust-helper-intl

Dust helpers for internationalization.

Installation

Browser

1. Install with bower: bower install dust-helper-intl
2. Load the scripts into your page.

<script src="dustjs-linkedin.js"></script>
<script src="dust-helper-intl.js"></script>

3. Register the helpers:

DustHelperIntl.register(dust);

Node/CommonJS

1. You can install the helpers with npm: npm install dust-helper-intl
2. Load in the module and register it:

var Dust = require('dustjs-linkedin');
global.Intl = global.Intl || require('intl');
require('dust-helper-intl').register(Dust);

NOTE: Since node (as of 0.10) doesn't provide the global Intl object (ECMA-402) you'll need to provide a polyfill. The intl NPM package can provide this or you can use another.

Usage

@intlDate

NOTE: We will use the following variables in the examples:

var dateStr = (new Date()).toString(); // 'Wed Mar 26 2014 15:18:48 GMT-0700 (PDT)'
var timeStamp = (new Date()).getTime();   // 1395872439650

Convert from date string

Template:

var tmpl = '<time>{@intlDate val="' + dateStr + '" /}</time>';

Output:

<time>3/26/2014</time>

Convert from timestamp

Template:

var tmpl = '<time>{@intlDate val=' + timeStamp + ' /}</time>';

or

var tmpl = '<time>{@intlDate val={timeStamp} /}</time>';
var ctx = { timeStamp : (new Date()).getTime() };

Output:

<time>3/26/2014</time>

Note: Timestamps are always numeric values, passing them as String will fail (see JavaScript Date constructor).

Formatting the output

Template:

var tmpl = '<time>{@intlDate val="' + dateStr + '" hour="numeric" minute="numeric" timeZone="UTC"/}</time>';

Output:

<time>3:26 PM</time>
