Bowser
------
A Browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.

So... it works like this:

``` js
if (bowser.msie && bowser.version <= 6) {
  alert('Hello China');
}
```

Detected Browsers[Engines]
-----

  * chrome[webkit]
  * firefox[gecko]
  * msie
  * opera[webkit if >12]
  * phantomjs[webkit]
  * safari[webkit]
  * seamonkey[gecko]
  * touchpad[webkit]

Detected mobile operating systems
-----

  * android
  * windows phone
  * ios (iphone/ipad/ipod)
  * blackberry
  * firefoxos
  * webos

Android, iOS and Windows Phone will all report the OS version number if it is contained in the UA string in the `osversion` field. iOS is always reported as `ios` and additionally as `iphone`/`ipad`/`ipod`, whichever one matches best. Windows Phone is reported as `windowsphone`.

All detected mobile OSes are additionally flagged `mobile`.

Notes
----
Safari, Chrome and some other minor browsers will report that they have `webkit` engines, Firefox and Seamonkey will report that they have `gecko` engines.

``` js
if (bowser.webkit) {
  // do stuff with safari & chrome
}
```

Ender installation
-----
If you don't already have [Ender](http://ender.no.de) (an npm package) install it now (and don't look back)

    $ npm install ender

then add bowser to your module collection

    $ ender add bowser

use it like this:

``` js
if ($.browser.chrome) {
  alert('Hello Silicon Valley');
}
```

Graded Browser Support
---------
One useful feature of Bowser is that aside from checking one browser from another -- it will keep up to date with [Yahoo's Graded Browser Support](http://developer.yahoo.com/yui/articles/gbs/) chart, giving you access to each grade on the bowser object

``` js
if (bowser.a) {
  // support full feature set
}
else if (bowser.c) {
  // serve degraded version
}
else {
  // unsupported (bowser.x)
}
```

Building
--------

If you'd like to contribute a change to bowser, modify the files in src/, then run the following (you'll need node + npm installed):

    $ npm install
    $ make


Testing
-------
We started a list `src/useragents.js` with example user agents and their expected bowser object.

Whenever you add support for new browsers or notice a bug / mismatch, please update the list and
check if all tests are still passing.

To run the test call `$ make test`
