# To see the full documentation of these classes, enter the following at

import rivendell.PyPAD
#
# First, we create a callback method, that will be called every time a
# log machine updates its PAD. Two arguments are supplied:
#
# update - An instance of 'PyPADUpdate' that contains the PAD information.
#
# priv - An arbitrary object that was passed to 'PyPADReceiver' using
# its 'setPrivateObject()' method. This allows initialiation to
# be done (create sockets, file handles, etc) before starting the
# receiver and then passing those objects to the processing callback.
#
def ProcessPad(update,priv):
print
if update.hasNowPad():
print update.padFields("NOW: %a - %t")
print "Log %03d NOW: " % update.logMachine()+update.padFields("%a - %t")
else:
print "NOW: [none]"
print "Log %03d NOW: [none]" % update.logMachine()
if update.hasNextPad():
print update.padFields("NEXT: %A - %T")
print "Log %03d NEXT: " % update.logMachine()+update.padFields("%A - %T")
else:
print "NEXT: [none]"
print "Log %03d NEXT: [none]" % update.logMachine()
#
# Create an instance of 'PyPADReceiver'
#
rcvr=rivendell.PyPAD.PyPADReceiver()
#
# Tell it to use the callback
#
rcvr.setCallback(ProcessPad)
#
# Start the receiver, giving it the hostname or IP address of the target
# Rivendell system. Once started, all further processing can only be done
# in the callback method!

rcvr.start("localhost")
