I have earlier asked this question, and I got good answers there. However, that was for beta4, and no longer works.

So where and how do I add my own view helpers to ZF2?

You should add them to your module.config.php under view_helpers like this:

'view_manager' => array(
    'template_path_stack' => array(
        'ModuleName' => __DIR__ . '/../view',
    ),
),

'view_helpers' => array(
    'factories' => array(
        'showmessages' => function($sm) {
            $helper = new ModuleName\Helper\MessageShower();
            // do stuff with $sm or the $helper
            return $helper;           
        },
    ),
    'invokables' => array(
        'selectmenu' => 'ModuleName\Helper\SelectMenu',   
        'prettyurl'  => 'ModuleName\Helper\PrettyUrl',
    ),  
),

Here I show two ways of creating the helpers. If all they need to do is to be instantiated, just add their name (including namespace) as invokables. If you need to do stuff with them or the ServiceManager, create them through the factories keyword.
