Intro to Cappuccinojason harwig

[cappuccino description]

• Open source (LGPL2)

• Client side (BYOBE)

• Web application Framework

[cappuccino background]

Extending JavaScript

• Classical Inheritance

• Imports

• No Compilation step (GWT)

Prototype, Jquery, Dojoextend without new syntax

var Animal = Class.create({ initialize: function(name, sound) { this.name = name; this.sound = sound; },

speak: function() { alert(this.name + " says: " + this.sound + "!"); }});

ES4, JS 2 Syntax

class C extends B { function C(m) { mem = m } public function getmem() { return mem } private var mem : Object};

create a superset of JavaScript

Extend a language without breaking legacy/future scripts?

Look to History Objective-C

Objective-Jsuperset of JavaScript

Objective-J Implementation

Objective-J

Preprocessor JavaScript

Objective-J File

• Valid JavaScript is valid Objective-J

• Syntax resembled Objective-CObjective-J File

import <Foundation/CPObject.j>@implementation Animal : CPObject{ CPString name; CPString sound;}- (void)speak{ alert(name + " says: " + sound + "!");}

Objective-J

Preprocessor

• Written in JavaScript

• No Plugin Required

• No Compile Step

Language Features

@import "MyClass.j"

@implementation CPString (Reversing)

- (CPString)reverse{ var reversedString = "", index = [self length]; while(index--) reversedString += [self characterAtIndex: index]; return reversedString;}
