How do Valas closures map to Genie?

Question

The Vala Tutorial has an example about DBus using anonymous methods.

Bus.own_name (BusType.SESSION, \"org.example.DemoService\", /* name to register */
              


        

Answer 1

I think there is not way. You must call another process using "def".

Bus.own_name (BusType.SESSION, "org.example.DemoService", 
          BusNameOwnerFlags.NONE, 
          on_bus_aquired, 
          reg,
          err);

def reg()
    pass

def err()
    print "error"

Answer 2

This isn't possible at the moment:

Currently Genie only support the deprecated lambda syntax for signals (+=). This patch provides lambda support in most constructs, the only requirement is that braces and parens need to be indent-balanced on multiple line constructs.
