Configuration System
My first code contribution, comments are welcome!

Config System Overview:
I created this configuration system, because I wasn't satisfied with the current approach and its integration examples in the EE tutorials. In addition I thought about an input class that manages and evaluate device inputs being mapped to certain function commands.
I wanted to create a small framework: easy to understand, flexible in use.

Features:

Easy to implement using an "Interface" (c++ abstract class) providing the minimum function set to be implemented with ease
Complete example of a PlayerInput class with Forward, Backward, TurnLeft and TurnRight command bind

Known issues:

The evaluation of the keyboard inputs are not yet finished, returning the flags for "button on", "button pushed", "button released", "button double clicked" are not fully supported at the moment.

   App.name("Configuration & Input");

   DataPath("../../Data");

   Paks.add("engine.pak");

   D.mode(800,600).sync(true).viewRange(200);

}

bool Init()

{

   // Load configuration of PlayerInput 

   input.cLoad();

   // Direct save, to create a file if it doesn't exist yet

   input.cSave();

   return true;

}

void Shut()

{

}

/******************************************************************************/

bool Update()

{

   // Update PlayerInput and read input variables from input devices

   input.updateInput();

   return true;

}

void Draw()

{

   D      .clear();

   D.text(0, 0.5, Str("Forward command: ") + input.forward());

   D.text(0, 0.4, Str("Backward command: ") + input.backward());

   D.text(0, 0.3, Str("TurnLeft command: ") + input.turnLeft());

   D.text(0, 0.2, Str("TurnRight command: ") + input.turnRight());

}

/******************************************************************************/

Maybe there are more features and issues, let me know and I'll add it here.

Man this is some sweet ass coding!
Very complex stuff and really impressive!
But it's broken :(

class BaseInput : ConfigurableInterface
{
.
.
.

// Variables
Int _connectedJoypad; // stores the index of connected Joypad
Map<Str,Str> _actionBinding(PlayerInput::MapABCreate, PlayerInput::MapABCompare); // successfully read command bindings
Map<Str,UInt> _functionKeys(PlayerInput::MapFKCreate, PlayerInput::MapFKCompare); // default map for command => KB conversions
};

// Description: Constructor, initalizes the _functionsKeys map with all KB_BUTTON
BaseInput.BaseInput()
{ //throws error here line 43
*_functionKeys("0") = KB_0;
*_functionKeys("1") = KB_1;
.
.
}

I'm going to try and debug it because it's very flexible, but I doubt I can.. my C++ is on the week side.

Edit: I just noticed your footer, the IRC link is wrong, it should be:
http://webchat.freenode.net/?channels=#Esenthel

Oh I see it's an esenthel update issue:
http://www.esenthel.com/community/showth...p?tid=4730
http://www.esenthel.com/community/showth...6#pid27896

-all custom Compare functions that want to be passed to memory containers search methods, and Map constructors now need to accept parameters in const mode "Compare(C TYPE &a, C TYPE &b)"

BaseInput file:

Added C to all inputs, but still fails
// Map related functions
static Bool MapABCreate(C Str &data, C Str &key, Ptr user) { return true; }
static Int MapABCompare(C Str &a, C Str &b) { return Compare(a, b); }
static Bool MapFKCreate(C UInt &data, C Str &key, Ptr user){ return true; }
static Int MapFKCompare(C Str &a, C Str &b) { return Compare(a, b); }

in the Map constructor the Compare function must now be first, Create function must be second and it is optional.

Thank you

I see it now in the header!
I would have never seen it, thanks grin

Map<Str, Str> _actionBinding(PlayerInput::MapABCompare,PlayerInput::MapABCreate) ; // successfully read command bindings
Map<Str,UInt> _functionKeys( PlayerInput::MapFKCompare,PlayerInput::MapFKCreate) ; // default map for command => KB conversions

Next issue was this line:
newEval.value = testAxisX ? Joypad[_connectedJoypad].dir_a.x : (testAxisY ? Joypad[_connectedJoypad].dir_a.y : 0.0f) * value;

error C2228: left of '.x' must have class/struct/union

Because dir_a is an array, adding [0] to the two dir_a[0].x compiles.
This only checks left stick.
