"""
Bridge Example
This example is quite similar to the Hello example
but displays a hello form both the parent and child
processing demonstrating how IPC works using the Bridge.
"""
from os import getpid
from circuits import Component, Event, ipc
class hello(Event):
"""hello Event"""
class Child(Component):
def hello(self):
return f'Hello from child with pid {getpid()}'
class App(Component):
def init(self):
Child().start(process=True, link=self)
def ready(self, *args):
x = yield self.call(hello())
yield print(x)
y = yield self.call(ipc(hello()))
yield print(y)
raise SystemExit(0)
def hello(self):
return f'Hello from parent with pid {getpid()}'
App().run()
