New page

Same example as above, this time with Inline Callbacks. Notice how readablity has improved over bare deferreds version:

#!/usr/bin/python
from twisted.internet import defer
from yaypm import AbandonedException
import logging, yaypm.utils

logger = logging.getLogger('yaypm.examples')

@defer.inlineCallbacks
def ivr(yate, callid):
try:
end = yate.onwatch("chan.hangup", lambda m : m["id"] == callid)

execute = yield yate.onwatch("call.execute",
lambda m : m["id"] == callid,
until = end)
targetid = execute["targetid"]

yate.msg("call.answered",
{"id": targetid,
"targetid": callid}).enqueue()

logger.debug("Call %s answered." % callid)

while True:
dtmf = yield yate.onmsg("chan.dtmf",
lambda m : m["id"] == callid,
end)

logger.debug("Dtmf %s received." % dtmf["text"])

yate.msg("chan.masquerade",
{"message" : "chan.attach",
"id": targetid,
"source": "wave/play/./sounds/digits/pl/%s.gsm" % \
dtmf["text"]}).enqueue()

dtmf.ret(True)

except AbandonedException, e:
logger.debug("Call %s abandoned." % callid)

@defer.inlineCallbacks
def route(yate):
while True:
route = yield yate.onmsg("call.route", lambda m : m["called"] == "ivr")
ivr(yate, route["id"])
route.ret(True, "dumb/")

if __name__ in ["__main__", "__embedded_yaypm_module__"]:
logger.setLevel(logging.DEBUG)
yaypm.utils.setup(lambda yate: route(yate))
