+# Intl.js [![Build Status][]](https://travis-ci.org/andyearnshaw/Intl.js)
+
+In December 2012, ECMA International published the first edition of Standard ECMA-402,
+better known as the _ECMAScript Internationalization API_. This specification provides
+the framework to bring long overdue localization methods to ECMAScript implementations.
+
+All modern browsers, except safari, have implemented this API. `Intl.js` fills the void of availability for this API. It will provide the framework as described by the specification, so that developers can take advantage of the native API
+in environments that support it, or `Intl.js` for legacy or unsupported environments.
+
+[Build Status]: https://travis-ci.org/andyearnshaw/Intl.js.svg?branch=master
+
+
+## Getting started
+
+### Intl.js and FT Polyfill Service
+
+Intl.js polyfill was recently added to the [Polyfill service][], which is developed and maintained by a community of contributors led by a team at the [Financial Times](http://www.ft.com/). It is available through `cdn.polyfill.io` domain, which routes traffic through [Fastly](http://www.fastly.com/), which makes it available with global high availability and superb performance no matter where your users are.
+
+To use the Intl polyfill through the [Polyfill service][] just add one script tag in your page before you load or parse your own JavaScript:
+
+```
+<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=Intl.~locale.en"></script>
+```
+
+When specifying the `features` to use through the polyfill service, you have to specify what locale, or locales to load along with the Intl polyfill for the page to function, in the example above we are specifying `Intl.~locale.en`, which means only `en`, but you could do something like this:
+
+```
+<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=Intl.~locale.fr,Intl.~locale.pt"></script>
+```
+
+_note: the example above will load the polyfill with two locale data set, `fr` and `pt`._
+
+This is by far the best option to use the Intl polyfill since it will only load the polyfill code and the corresponding locale data when it is really needed (e.g.: safari will get the code and patch the runtime while chrome will get an empty script tag).
+
+[Polyfill service]: https://cdn.polyfill.io/v1/docs/
+
+### Intl.js and Node
+
+For Node.js applications, you can install `intl` using NPM:
+
+    npm install intl
+
+Node.js 0.12 has the Intl APIs built-in, but only includes the English locale data by default. If your app needs to support more locales than English, you'll need to [get Node to load the extra locale data](https://github.com/nodejs/node/wiki/Intl), or use `intl` npm package to patch the runtime with the Intl polyfill. Node.js versions prior to 0.12 and ≥v3.1 don't provide the Intl APIs, so they require that the runtime is polyfilled.
+
+The following code snippet uses the intl polyfill and [intl-locales-supported](https://github.com/yahoo/intl-locales-supported) npm packages which will help you polyfill the Node.js runtime when the Intl APIs are missing, or if the built-in Intl is missing locale data that's needed for your app:
+
+```javascript
+var areIntlLocalesSupported = require('intl-locales-supported');
+
+var localesMyAppSupports = [
+    /* list locales here */
+];
+
+if (global.Intl) {
+    // Determine if the built-in `Intl` has the locale data we need.
+    if (!areIntlLocalesSupported(localesMyAppSupports)) {
+        // `Intl` exists, but it doesn't have the data we need, so load the
+        // polyfill and patch the constructors we need with the polyfill's.
+        var IntlPolyfill    = require('intl');
+        Intl.NumberFormat   = IntlPolyfill.NumberFormat;
+        Intl.DateTimeFormat = IntlPolyfill.DateTimeFormat;
+    }
+} else {
+    // No `Intl`, so use and load the polyfill.
+    global.Intl = require('intl');
+}
+```
+
+### Intl.js and Browserify/webpack
+
+If you build your application using [browserify][] or [webpack][], you will install `intl` npm package as a dependency of your application. Ideally, you will avoid loading this library if the browser supports the
+built-in `Intl`. An example of conditional usage using [webpack][] _might_ look like this:
+
+```javascript
+function runMyApp() {
+    var nf = new Intl.NumberFormat(undefined, {style:'currency', currency:'GBP'});
+    document.getElementById('price').textContent = nf.format(100);
+}
+if (!global.Intl) {
+    require.ensure([
+        'intl',
+        'intl/locale-data/jsonp/en.js'
+    ], function (require) {
+        require('intl');
+        require('intl/locale-data/jsonp/en.js');
+        runMyApp()
+    });
+} else {
+    runMyApp()
+}
+```
+
+_note: a similar approach can be implemented with [browserify][], althought it does not support `require.ensure`._
+
+_note: the locale data is required for the polyfill to function when using it in a browser environment, in the example above, the english (`en`) locale is being required along with the polyfill itself._
+
+[webpack]: https://webpack.github.io/
+[browserify]: http://browserify.org/
+
+### Intl.js and Bower
+
+Intl.js is also available as a [Bower](http://bower.io) component for the front-end:
+
+    bower install intl
+
+Then include the polyfill in your pages as described below:
+
+```html
+<script src="path/to/intl/Intl.js"></script>
+<script src="path/to/intl/locale-data/jsonp/en.js"></script>
+```
+
+_note: use the locale for the current user, instead of hard-coding to `en`._
+
+## Status
+Current progress is as follows:
+
+### Implemented
+ - All internal methods except for some that are implementation dependent
+ - Checking structural validity of language tags  
+ - Canonicalizing the case and order of language subtags
+ - __`Intl.NumberFormat`__
+   - The `Intl.NumberFormat` constructor ([11.1](http://www.ecma-international.org/ecma-402/1.0/#sec-11.1))
+   - Properties of the `Intl.NumberFormat` Constructor ([11.2](http://www.ecma-international.org/ecma-402/1.0/#sec-11.2))
+   - Properties of the `Intl.NumberFormat` Prototype Object ([11.3](http://www.ecma-international.org/ecma-402/1.0/#sec-11.3))
+   - Properties of Intl.NumberFormat Instances([11.4](http://www.ecma-international.org/ecma-402/1.0/#sec-11.4))
+ - __`Intl.DateTimeFormat`__
+   - The `Intl.DateTimeFormat` constructor ([12.1](http://www.ecma-international.org/ecma-402/1.0/#sec-12.1))
+   - Properties of the `Intl.DateTimeFormat` Constructor ([12.2](http://www.ecma-international.org/ecma-402/1.0/#sec-12.2))
+   - Properties of the `Intl.DateTimeFormat` Prototype Object ([12.3](http://www.ecma-international.org/ecma-402/1.0/#sec-12.3))
+   - Properties of Intl.DateTimeFormat Instances([12.4](http://www.ecma-international.org/ecma-402/1.0/#sec-12.4))
+ - Locale Sensitive Functions of the ECMAScript Language Specification
+   - Properties of the `Number` Prototype Object ([13.2](http://www.ecma-international.org/ecma-402/1.0/#sec-13.2))
+   - Properties of the `Date` prototype object ([13.3](http://www.ecma-international.org/ecma-402/1.0/#sec-13.3))
+
+### Not Implemented
+ - `BestFitSupportedLocales` internal function
+ - Implementation-dependent numbering system mappings
+ - Calendars other than Gregorian
+ - Support for time zones
+ - Collator objects (`Intl.Collator`) (see below)
+ - Properties of the `String` prototype object
+
+A few of the implemented functions may currently be non-conforming and/or incomplete.  
+Most of those functions have comments marked as 'TODO' in the source code.
+
+The test suite is run with Intl.Collator tests removed, and the Collator
+constructor removed from most other tests in the suite.  Also some parts of
+tests that cannot be passed by a JavaScript implementation have been disabled,
+as well as a small part of the same tests that fail due to [this bug in v8][].
+
+ [this bug in v8]: https://code.google.com/p/v8/issues/detail?id=2694
+
+
+## What about Intl.Collator?
+
+Providing an `Intl.Collator` implementation is no longer a goal of this project. There
+are several reasons, including:
+
+ - The CLDR convertor does not automatically convert collation data to JSON
+ - The Unicode Collation Algorithm is more complicated that originally anticipated,
+   and would increase the code size of Intl.js too much.
+ - The Default Unicode Collation Element Table is huge, even after compression, and
+   converting to a native JavaScript object would probably make it slightly larger.
+   Server-side JavaScript environments will (hopefully) soon support Intl.Collator,
+   and we can't really expect client environments to download this data.
+
+
+## Compatibility
+Intl.js is designed to be compatible with ECMAScript 3.1 environments in order to
+follow the specification as closely as possible. However, some consideration is given
+to legacy (ES3) environments, and the goal of this project is to at least provide a
+working, albeit non-compliant implementation where ES5 methods are unavailable.
+
+A subset of the tests in the test suite are run in IE 8.  Tests that are not passable
+are skipped, but these tests are mostly about ensuring built-in function behavior.
+
+
+## Locale Data
+`Intl.js` uses the Unicode CLDR locale data, as recommended by the specification. The main `Intl.js` file contains no locale data itself. In browser environments, the
+data should be provided, passed into a JavaScript object using the
+`Intl.__addLocaleData()` method.  In Node.js, or when using `require('intl')`, the data
+is automatically added to the runtime and does not need to be provided.
+
+Contents of the `locale-data` directory are a modified form of the Unicode CLDR

+## RegExp cache / restore
+`Intl.js` attempts to cache and restore static RegExp properties before executing any
+regular expressions in order to comply with ECMA-402.  This process is imperfect,
+and some situations are not supported.  This behavior is not strictly necessary, and is only
+required if the app depends on RegExp static properties not changing (which is highly
+unlikely).  To disable this functionality, invoke `Intl.__disableRegExpRestore()`.

+   *
+   * This polyfill defines the algorithm to be the same as BasicFormatMatcher,
+   * with the addition of bonus points awarded where the requested format is of

+   * This algo relies on the concept of closest distance matching described here:
+   * http://unicode.org/reports/tr35/tr35-dates.html#Matching_Skeletons
+   * Typically a “best match” is found using a closest distance match, such as:
+   *
+   * Symbols requesting a best choice for the locale are replaced.
+   *      j → one of {H, k, h, K}; C → one of {a, b, B}
+   * -> Covered by cldr.js matching process
+   *
+   * For fields with symbols representing the same type (year, month, day, etc):
+   *     Most symbols have a small distance from each other.
+   *         M ≅ L; E ≅ c; a ≅ b ≅ B; H ≅ k ≅ h ≅ K; ...
+   *     -> Covered by cldr.js matching process
+   *
+   *     Width differences among fields, other than those marking text vs numeric, are given small distance from each other.
+   *         MMM ≅ MMMM
+   *         MM ≅ M
+   *     Numeric and text fields are given a larger distance from each other.
+   *         MMM ≈ MM
+   *     Symbols representing substantial differences (week of year vs week of month) are given much larger a distances from each other.
+   *         d ≋ D; ...
+   *     Missing or extra fields cause a match to fail. (But see Missing Skeleton Fields).
+   *
+   *
+   * For example,
+   *
+   *     { month: 'numeric', day: 'numeric' }
+   *
+   * should match
+   *
+   *     { month: '2-digit', day: '2-digit' }
+   *
+   * rather than
+   *
+   *     { month: 'short', day: 'numeric' }

+ * When the BestFitFormatMatcher abstract operation is called with two arguments options
+ * and formats, it performs implementation dependent steps, which should return a set of
+ * component representations that a typical user of the selected locale would perceive as
+ * at least as good as the one returned by BasicFormatMatcher.
+ *
+ * This polyfill defines the algorithm to be the same as BasicFormatMatcher,
+ * with the addition of bonus points awarded where the requested format is of
+ * the same data type as the potentially matching format.
+ *
+ * This algo relies on the concept of closest distance matching described here:
+ * http://unicode.org/reports/tr35/tr35-dates.html#Matching_Skeletons
+ * Typically a “best match” is found using a closest distance match, such as:
+ *
+ * Symbols requesting a best choice for the locale are replaced.
+ *      j → one of {H, k, h, K}; C → one of {a, b, B}
+ * -> Covered by cldr.js matching process
+ *
+ * For fields with symbols representing the same type (year, month, day, etc):
+ *     Most symbols have a small distance from each other.
+ *         M ≅ L; E ≅ c; a ≅ b ≅ B; H ≅ k ≅ h ≅ K; ...
+ *     -> Covered by cldr.js matching process
+ *
+ *     Width differences among fields, other than those marking text vs numeric, are given small distance from each other.
+ *         MMM ≅ MMMM
+ *         MM ≅ M
+ *     Numeric and text fields are given a larger distance from each other.
+ *         MMM ≈ MM
+ *     Symbols representing substantial differences (week of year vs week of month) are given much larger a distances from each other.
+ *         d ≋ D; ...
+ *     Missing or extra fields cause a match to fail. (But see Missing Skeleton Fields).
+ *
+ *
+ * For example,
+ *
+ *     { month: 'numeric', day: 'numeric' }
+ *
+ * should match
+ *
+ *     { month: '2-digit', day: '2-digit' }
+ *
+ * rather than
+ *
+ *     { month: 'short', day: 'numeric' }
+ *
+ * This makes sense because a user requesting a formatted date with numeric parts would
+ * not expect to see the returned format containing narrow, short or long part names
