Question

Suppose I have the following functions:

public function vardump($var, $controller = false)
{
    ob_start();
    $this->_vardump($var, (bool)$controller);
    $output = ob_get_clean();
    if ($controller) {
         $controller->BResponse->set($output)->output('text/html');
    } else {
         // output to file
    }
}

/**
 * Reference BDebug::dump()
 */
protected function _vardump($var, $isController)
{
    // some code similar to BDebug::dump()   
}

The above would be inside a helper in Magento, which can be called anywhere. In Sellvana, there is no such thing, or is there? So, I think I can add that to the BDebug class. And I want to be able to call vardump like this:

// in a controller
return  $this->BDebug->vardump($var, $this); 
// in other classes
return $this->BDebug->vardump($var);

However, I don't know what's bootstrapping, so how do I create the bootstrap method:

BModuleRegistry::i()->addMethod('BDebug', 'vardump', $whatIscallback);

What should be $callback, is there a code snippets I can reference? [edit] I got it working now.

And I'm trying the override method: [edit] I still need to get this to work.

modules:
    Celera_Clog:
        version: 0.1.0
        require: { module: [ FCom_Core ] }
        description: "Celera Clog Module"
        areas:
            FCom_Frontend:
                routing:
                    - [ /clog, Celera_Clog_Frontend_Controller.index ]
                    - [ /clog/info, Celera_Clog_Frontend_Controller.info ]
                    - [ /clog/ip, Celera_Clog_Frontend_Controller.ip ]
        override:
            module:
                - [ BDebug, Celera_Clog_Debug ]

I created a file class Celere_Clog_Debug extends BDebug and inserted the vardump functions in it. This returns ERROR: Invalid method: BDebug::vardump (core/FCom/Core/buckyball/com/core.php:1320). How do I fix it?

[EDIT]
I manged to figure out how to addMethod:

manifest.yml

modules:
    Celera_Clog:
        version: 0.1.0
        require: { module: [ FCom_Core ] }
        description: "Celera Clog Module"
        bootstrap: { file: Debug.php, callback: [Celera_Clog_Debug, bootstrap] }
        areas:
            FCom_Frontend:
                routing:
                    - [ /clog, Celera_Clog_Frontend_Controller.index ]
                    - [ /clog/info, Celera_Clog_Frontend_Controller.info ]
                    - [ /clog/ip, Celera_Clog_Frontend_Controller.ip ]
        #override:
         #   module:
          #      - [ BDebug, Celera_Clog_Debug ]

The bootsrap file:

class Celera_Clog_Debug extends BDebug
{
  public static function bootstrap()
  {
      //BModuleRegistry::i()->addMethod('BDebug', 'vardump', ['Celera_Clog_Debug', 'vardump']); // this returns an error: Invalid method
      BClassRegistry::i()->addMethod('BDebug', 'vardump', ['Celera_Clog_Debug', 'vardump']);
  }

  public static function vardump()
  {
      $var = func_get_args();
      #ob_start();
      #self::_vardump($var);
      #$output = ob_get_clean();
      $controller->BResponse->set('testing')->output('text/html');
  }

Thank you for the question, sorry about the delay, didn't get notification!

Looks like you've got it working. There's an easier convention, in manifest.yml instead of:

bootstrap: { file: Debug.php, callback: [Celera_Clog_Debug, bootstrap] }

replace with (choose ones you need):

auto_use: [ bootstrap, layout, views ]

This will invoke this class method (no need to extend BDebug):

class Celera_Clog_Main extends BClass
{
    public function bootstrap()
    {
        $this->BClassRegistry->addMethod('BDebug', 'vardump', [$this, 'vardump']);
    }

    public function vardump()
    {
        $var = func_get_args();
        #ob_start();
        #self::_vardump($var);
        #$output = ob_get_clean();
        $controller->BResponse->set('testing')->output('text/html');
    }
}
