Working example

Here's a functional example that you can paste into a Main.hx for trying out unject:

Main.hx

package ;

import unject.StandardKernel;
import unject.UnjectModule;
import haxe.rtti.Infos;

class Main
{
	public static function main()
	{
		var kernel = new StandardKernel([new TestModule()]);

		var samurai = kernel.get(Samurai);
		var katana = kernel.get(Katana);

		trace(samurai.attack("the evildoers"));
		trace("The katana has sharpness " + katana.sharpness);
	}
}

class TestModule extends UnjectModule
{
	public override function load()
	{
		bind(Katana).toSelf().withParameter("sharpness", 100);
		bind(Samurai).toSelf();		
		bind(IWeapon).to(Sword);		
	}
}

class Katana implements Infos
{
	public var sharpness : Int;

	public function new(sharpness : Int)
	{
		this.sharpness = sharpness;
	}
}

class Samurai implements Infos
{
	var weapon : IWeapon;

	public function new(weapon : IWeapon)
	{
		this.weapon = weapon;
	}

	public function attack(target : String)
	{
		return weapon.hit(target);
	}
}

class Sword implements IWeapon, implements Infos
{
	public function new();

	public function hit(target : String)
	{
		return "Chopped " + target + " in half.";
	}
}

interface IWeapon 
{
	public function hit(target:String):String;
}

Compile and run from command line with:

haxelib install unject
haxe -main Main -x Main.hx -lib unject
