# Platform.js <sup>v1.0.0-pre</sup>
A platform detection library that works on nearly all JavaScript platforms<sup><a name="fnref1" href="#fn1">1</a></sup>.
## Disclaimer
Platform.js is for informational purposes only and **not** intended as a substitution for [feature detection/inference](http://allyoucanleet.com/post/18087210413/feature-testing-costs#screencast2) checks.
## BestieJS
Platform.js is part of the BestieJS *"Best in Class"* module collection. This means we promote solid browser/environment support, ES5 precedents, unit testing, and plenty of documentation.
## Documentation
The documentation for Platform.js can be viewed here: [/doc/README.md](https://github.com/bestiejs/platform.js/blob/master/doc/README.md#readme)
For a list of upcoming features, check out our [roadmap](https://github.com/bestiejs/platform.js/wiki/Roadmap).
## Installation and usage
In a browser or Adobe AIR:
~~~ html
<script src="platform.js"></script>
~~~
Via [npm](http://npmjs.org/):
~~~ bash
npm install platform
~~~
In [Narwhal](http://narwhaljs.org/), [Node.js](http://nodejs.org/), and [RingoJS](http://ringojs.org/):
~~~ js
var platform = require('platform');
~~~
In [Rhino](http://www.mozilla.org/rhino/):
~~~ js
load('platform.js');
~~~
In an AMD loader like [RequireJS](http://requirejs.org/):
~~~ js
require({
'paths': {
'platform': 'path/to/platform'
}
},
['platform'], function(platform) {
console.log(platform.name);
});
~~~
Usage example:
~~~ js
// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'
// or on an iPad
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
platform.os; // 'iOS 5.0'
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'
// or parsing a given UA string
var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
info.name; // 'Opera'
info.version; // '11.52'
info.layout; // 'Presto'
info.os; // 'Mac OS X 10.7.2'
info.description; // 'Opera 11.52 (identifying as Firefox 4.0) on Mac OS X 10.7.2'
~~~
## Footnotes
1. Platform.js has been tested in at least Adobe AIR 2.6, Chrome 5-15, Firefox 1.5-8, IE 6-10, Opera 9.25-11.52, Safari 2-5.1.1, Node.js 0.4.8-0.6.1, Narwhal 0.3.2, RingoJS 0.7-0.8, and Rhino 1.7RC3.
