Laravel 4 App library using Service Provider and Facade

<?php
//based on: http://fideloper.com/create-facade-laravel-4

//-------------------------------------------------------------
// Setting Awal
// - Buat folder library di app/libraries/
// - Update composer.json
//    "autoload": {
//       "classmap": [
//          "app/libraries",
//-------------------------------------------------------------


//-------------------------------------------------------------
// Contoh class library, misal mau buat library debug kecil2an
// disimpan di: app/libraries/debugger/Debugger.php
//-------------------------------------------------------------

<?php namespace Libraries;

use DB;

class Debugger {

    public function dd($var)
    {
        echo '<pre>';
        dd($var);
    }

    public function pr($var)
    {
        echo '<pre>';
        print_r($var);
        die;
    }

    public function prQuery()
    {
        $this->pr(DB::getQueryLog());
    }

    public function ddQuery()
    {
        $this->dd(DB::getQueryLog());
    }

}

//-------------------------------------------------------------
// buat Service Provider untuk library diatas
// disimpan di: app/libraries/debugger/DebuggerServiceProvider.php
//-------------------------------------------------------------

<?php namespace Libraries;

use Illuminate\Support\ServiceProvider;

class DebuggerServiceProvider extends ServiceProvider {

    public function register()
    {
        $this->app->bind('Debugger', function()
        {
            return new Debugger;
        });
    }
}

//-------------------------------------------------------------
// buat Facade untuk library diatas
// disimpan di: app/libraries/debugger/DebuggerFacade.php
//-------------------------------------------------------------

<?php namespace Libraries\Facades;

use Illuminate\Support\Facades\Facade;

class Debugger extends Facade {

    protected static function getFacadeAccessor()
    {
        return 'Debugger';
    }
}

//-------------------------------------------------------------
// Daftarkan ServiceProvider dan Facade di app/config/app.php
// > service provider: 'Libraries\DebuggerServiceProvider'
// > facade: 'Debugger' => 'Libraries\Facades\Debugger'
// update autoload composer dengan command: composer dump-autoload
//-------------------------------------------------------------

// Selesai.
// Gunakan dimana saja secara statis, misal:
Debugger::pr($Input::all());
Debugger::ddQuery();
