Flash, Javascript o ...

Haxe targets

• Desktop App (C++, Neko, AIR...)• Web (JS, Flash, HTML)• Server Side (PHP, NodeJS, C#, Java...)• iOS• Android• Playbook

Roadmap Haxe

• Attualmente è scaricabile Haxe 2.09

• Estate 2012 Haxe 3

• Si sta già lavorando ad Haxe 4 con la rivoluzione di avere 1 unico linguaggio di programmazione per ogni target

haxe 2.09 compilazione su server + interactive debugging JS su Chrome e Firefox grazie al source mapping + haxe --dead-code-

haxe 3:

Non è tutto oro quel che luccica

• Implementazione Editor

• DEBUGGER (!!!!!)

• Integrazione “Adobbiana” verso i programmi grafici e non solo

• DOCUMENTAZIONE (!!!!!)

Differenze Haxe vs AS3package org.matterhaxe{ import flash.display.Sprite;

[SWF] public class MyClass extends Sprite { private var myVar1:Boolean protected var myVar2:int internal var myVar3:Number

public static const CIAO:String = "CIAO";

public function MyClass() { // constructor } private function myMethod1():void { trace(CIAO) } }}

package org.matterhaxe;

import nme.display.Sprite;import nme.Lib;

class MyClass extends Sprite{ private var myVar1: Bool; private var myVar2:Int; private var myVar3:Float;;

inline public static var CIAO:String = "CIAO";

public function new() { super(); } function myMethod():Void { trace(CIAO); } // static main function public static function main() { Lib.current.addChild( new MyClass() ); }}

Package & Classes

package org.matterhaxe;

import nme.display.Sprite;import nme.display.*; <<<< NOOO!!!!

class MyClass extends Sprite, implements IMyInterface

Access Modifier & Keywords

- solo private e public

- default è private

- non c'è const, c'è solo var

- c'è inline per variabili e metodiinline static var CICCIO:String = "Ciao";

Basic Types

- Void, Int, Bool, Float

- Dynamic var ciccio: Dynamic = "Ciccio"; ciccio = 4; ciccio = new Ciccio();

- Solo lettera maiuscola!!!

Constructor & Main

Costruttore di classepublic function new() {}

static public function main():Void { Lib.current.addChild(new MyClass);}

Type Parameters(generics & beyond)

AS3:- Vector.<T>

Haxe:- Built in: Array<T>, Vector<T>, Hash<T>- Custom: MyClass<T>- Type Constraints!!! MyClass<T: (ClassA, InterfaceB)>

Typedefstypedef MyType {

var field1:Int; var field2:Bool;}var pippo: MyType = { 4, true };

typedef Ugo = MyVeryVeryLongNamedClass;var ugo:Ugo = new Ugo();

Iteratorsfor( i in 0...100){

trace(i);}

for( i in myStringsArray){ trace(i);}custom: implementare i metodi del tipo "Iterator" nella classe       function hasNext() : Bool;     function next() : T;

Function PointersAS3

function myFunction (a:int,b:Number):void{}var myVar:Function = myFunction;

Haxefunction myFunction(a:Int,b:Float):Void{};var myVar:Int->Float->Void = myFunction;

CastTom Cruise - Maverick

Kelly McGillis - CharlieVal Kilmer - IcemanAnthony Edwards - GooseTom Skerrit - ViperMichael Ironside - JesterJohn Stockwell - CougarBarry Tubb - Wolfman

Cast- safe casting:

var car:Car = cast(vehicle,Car);- unsafe casting:var car:Car = cast vehicle;- Std casting:var toString = Std.string(10);var toNumber = Std.parseFloat("10");var toInteger = Std.int(10.1);

NME is a free, open-source framework that enables development for iOS, Android, webOS, BlackBerry, Windows, Mac, Linux and Flash Player from a single codebase
