Cornwall provides a bridge between Titanium WebViews and the Titanium

javascript environment. 

Uses

----

One application can be to use a webview centric design while exposing the full native

Titanium API (much like competing cross-platform frameworks).

In general however it simply provides a more powerful way of intergrating

Titanium with WebViews you may use in your app.

Watch the following [demo video](http://www.youtube.com/watch?v=2lVEZGhlP8M).

 

(Initial inspiration was really from [here](http://venturebeat.com/2012/05/02/linkedin-ipad-app-engineering/)).

Getting Started

---------------

Have a look at the included `app.js` and `index.html` files for

examples. The Cornwall files are in the `lib` directory. 

In your html file included the `Cornwall.js` file as follows:

```html

```

Require the `CornwallWebView` CommonJS modules and use it as you would

normally do with a Titanium WebView. For example:

```javascript

var web = new (require("/lib/CornwallWebView"))({

  url: "index.html"

});

```

The following additional boolean property

`loadFromContextUrl` can be set to `true` if you want to load Cornwall

code from webpages. (See below.)

Also the additional `cleanup` method should be called prior to removing

a CornwallWebView or closing a window containing it.   

Using Cornwall

--------------

To execute Titanium Code from your webview use the `Cornwall.execute`

command, e.g.:

```javascript

Cornwall.execute(function() {

  Titanium.Contacts.showContacts({});

});

```

If you want to return values back to the webview, wrap a function in

your webview with a `Cornwall.callback`, for example:

```javascript

var web_popup = function(a) {

  alert("Returned 'a' from Native: " + a.a);

};

Cornwall.execute(function() {

  Cornwall.callback(web_popup)({a:  "A"});

});

```

Note that the javascript code that is execute "over the bridge" is

evaluated in that context. If you want to pass variables across the

bridge follow this example:

```javascript

var start = new Date();

var text = 'Hello World';

Cornwall.execute(function(start, text) {

  alert("Started: " + start + "\Text: " + text);

},start, text);

```

Use in Webpages

---------------

Currently this feature is iOS only.

If you want to see how to use Cornwall in a webpage look at the example

in the `example` directory. Fire up the static webserver enter `node server.js` 

then go to `http://[your-ip-address]:8888` in Safari from your

iPhone.

Any `cornwall://` links from your browser will be

launched in Cornwall to give you the ability to execute native code

from the web.
