refer to self in a decorator on a class method

[Yuccaplant]

Hi all,

I would like to do something like this:

********************
class HelloWorld (object):

def __init__(self,clk):
self.clk = clk

@always(self.clk.posedge)
def sayHello(self):
print "%s Hello World!" % now()
********************

Problem is however I can't refer to self in the decorator call. Is
there any workarround?

thanks a lot,

pieter

Pass attribute names:
.... def always(f):
.... def wrapper(self, *args, **kw):
.... print attrgetter(name)(self)
.... return f(self, *args, **kw)
.... return wrapper
.... return always
........ def __init__(self, clk):
.... self.clk = clk
.... @always("clk.posedge")
.... def hello(self):
.... print "hello world"
........ posedge = 42
....42
hello world

There may be better ways depending on your usecase.
