JUL - The JavaScript UI Language

About

The JavaScript UI Language (JUL) is a configuration and instantiation module for the JavaScript frameworks. It can be used with any framework that accepts a configuration object as a constructor parameter, or with a custom factory for the other frameworks.

Browser support

JUL supports all major browsers including FF4+, IE8+, Safari4+, Chrome1+, Opera10+. JUL also works in various mobile browsers and in Node.js.

Install the Node module

Local:

npm install jul

Global:

npm install -g jul

Usage the Node’s way

var jul = require('jul');
// a configuration object 
var tree = {name: 'Main', id: 'NS.tree', size: 5,
    children: [{name: 'Child1', left: 2, top: 2}, {name: 'Child2', widths: [4, 8, 12]}]
};
// create a parser 
var parser = jul.parser();
// instantiate the configuration object 
parser.create(tree);
// create a JUL.Ref reference to the exported variable NS.tree 
var ref = jul.ref(NS, 'tree');
// print the instantiated object 
console.log(parser.obj2str(ref.val()));
// the same result using a JUL instance bound to a local namespace
var localVar = {};
var localJul = jul.instance({nsRoot: localVar});
// create a parser 
var localParser = localJul.parser({defaultClass: 'global.Object'});
// instantiate the configuration object 
localParser.create(tree);
// create a JUL.Ref reference to the exported variable localVar.NS.tree 
var localRef = jul.ref(localVar.NS, 'tree');
// print the instantiated object 
console.log(localParser.obj2str(localRef.val()));

Usage the JUL’s way

// Add "jul.js" as an external JS in the web page, or require('jul') in Node. 
// JUL & tools always remain global namespaces. 
 
// a configuration object 
var oTree = {name: 'Main', id: 'NS.tree', size: 5,
    children: [{name: 'Child1', left: 2, top: 2}, {name: 'Child2', widths: [4, 8, 12]}]
};
// create a parser 
var oParser = new JUL.UI.Parser();
// instantiate the configuration object 
oParser.create(oTree);
// create a JUL.Ref reference to the exported variable NS.tree 
var oRef = new JUL.Ref(NS, 'tree');
// print the instantiated object 
document.write(oParser.obj2str(oRef.val()));
// the same result using a JUL instance bound to a local namespace
var oLocalVar = {};
var oLocalJul = new JUL.Instance({nsRoot: oLocalVar});
// create a parser 
var oLocalParser = new oLocalJul.ui.Parser({defaultClass: 'global.Object'});
// instantiate the configuration object 
oLocalParser.create(oTree);
// create a JUL.Ref reference to the exported variable oLocalVar.NS.tree 
var oLocalRef = new JUL.Ref(oLocalVar.NS, 'tree');
// print the instantiated object 
document.write(oLocalParser.obj2str(oLocalRef.val()));
