Instance Method Details

#def_hook(event) ⇒ Object

Creates a wrapper method for #add_hook that doesn’t require the event to be passed. For example, calling:

def_hook :on_init

will create a on_init method, that can be used as:

on_init { |*_| puts 'I initialized' }

It’s the same as calling:

add_hook(:on_init) { |*_| puts 'I initialized' }
