Codeigniter HMVC + Rest_Controller with Dynamic Module Path

Question

I am working on creating an application with having an HMVC structure in codeigniter and i also require API Centric application , so i used https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc for HMVC and Rest_Controller of Phil Sturgeon, now everything is working fine , but the problem is for each controller in the module i have to add the static path

require APPPATH.'modules/modulename/libraries/REST_Controller.php'; 

i want to make this path dynamic , or auto load libraries for each module in the module's library folder, adding library name in the module/config/autoload.php is not working for me , as i think the reason is the code flow of application, first the application flow goes to the controller and it gets to my class extending the REST_Controller and gives the error , unable to load the REST_Controller Class

Note: if i put the Rest_Controller.php and Format.php in the application/libraries/ folder, everything works fine , but i want this to be modular , and make the module restful

how can i load libraries specifically from the module/libraries how to make it proper modular, so that there should be a complete instance of codeigniter in the module ,it should work freely, including the files loaded from the main application.

My folder structure is as follows

application
- - modules
- - - - modulename
- - - - - - controller
- - - - - - libraries
- - - - - - config
- - - - - - models
- - - - - - views

My Rest_Controller Class in the application/modules/module_name/libraries/Rest_Controller.php

abstract class REST_Controller extends MX_Controller

My Controller Class in application/modules/module_name/controllers/User.php

require APPPATH.'modules/modulename/libraries/REST_Controller.php';
class User extends REST_Controller
{

this works fine but if i remove the require line from the top , it doesn't work and even if i add the library name to autoload.php in the /modulename/config/autoload.php

it doesn't work My autoload.php /application/modules/modulename/config/autoload.php

<?phpif ( ! defined('BASEPATH')) exit('No direct script access allowed');
$autoload['packages'] = array();
$autoload['libraries'] = array('database', 'session','modulename/REST_Controller');
$autoload['helper'] = array('url', 'file');
$autoload['config'] = array();
$autoload['language'] = array();
$autoload['model'] = array();

and autoload.php in my application/config/autoload.php is empty, means no autoload mentioned

First - it isn't clear but your structure should look like this:

application
- - modules
- - - - modulename
- - - - - - controller
- - - - - - - modulename.php
- - - - - - libraries
- - - - - - - Rest_Conctroller.php
- - - - - - config
- - - - - - - autoload.php
- - - - - - models
- - - - - - views

Then use

$this->load->library('rest_controller');

Within your modulename.php controller to check it works first of all and you have all the paths defined correctly.

If it works then comment that line out first of all.

Then within your autoload.php file in your modulename/config folder just set:

$autoload['libraries'] = array('rest_controller');

Then try it again - notice there is nothing before the class name.

This will definitely work as I have tried it - if it doesn't it seems you have either modified your routes incorrectly or have been playing with files elsewhere (maybe over-ridden something in a custom controller?)
