How to add code that Waf always executes before exiting?

Question

I want to make Waf generate a beep when it completes any command that took more than 10 seconds.

I do not know how to add this and assure that the code is executed when Waf exits.

This should be done for any Waf team, not just for assembly.

I checked the Waf book , but I could not find any directions on how to do this.

In your module, wscriptyou can use the standard atexit Python library to register the calls you want to call when the process exits. For instance:

import atexit
import time

class MayBeep(object):
  def __init__(self, deadline=10.0):
    self.deadline = time.time() + deadline
  def __call__(self):
    if time.time() > self.deadline():
      print '\7'

atexit.register(MayBeep())

... rest of your wscript module ...

, - , print '\7' ( , , Python ), Q - , ".
