A small framework to create and customize Alloy widgets from controller.

Documentation is visible right here : libwidget documentation.

An overview of the framework is also accessible on github : quick examples.

Copy the libWidget.js inside your lib folder; then in your app/alloy.js, just require the library as follow :

var libWidget = require("libWidget").init();

Then, every widget or component that is also requesting the library will work.

In the widget's controller, you can declare rules describing how to dispatch TSS properties from controller over widget's views. Rules define in fact an interface usable from inside a .tss file and allow you to manipulate widget's properties through this interface.

Libwidget also allows you to declare a construct method inside your controller. Then, when a controller is instantiated by Alloy, the construct method will be automaticcaly called. It is a good way to initialize your widget properties such as rules.

For example, inside myWidgetController.js :

var libWidget = require("libWidget").newBuilder(this);

_.extend(this, {
    construct: function (config) {
        libWidget.addRules({
            "accessor1" : "#elem.internalProperty", 
            "accessor2" : ["#elem2.aProperty", "#elem3.anotherOne"],
            "accessor3" : function(value) {
                $.elem.setSomething(value);
                libWidget.addProperty("elem2", "internalProperty2", value == "condition" ?
                "thisText" : "orThisOne");
            },
            "accessor4" : "#elem4"
        });
        libWidget.build(config);
    },

    ... // Some code 

});

According to the fact that the app is using myWidget based on the controller above. Inside the app, myView.xml :

<Alloy>
    <Window>
        <Widget src="myWidget" id="myWidget" />
    </Window>
</Alloy>

And, in a corresponding .tss file of the app :

    "#myWidget": {
        accessor1: 14,
        accessor2: "red",
        accessor3: "notCondition",
        accessor4: {
            nested1: 42,
            nested2: {
                overNested: 1337,
                overNested2: "banana"
            }   
        }
    }
