I'm working on an asyncio server project. I'd also like to have a cmd.Cmd
style command loop interface for spawning instances of the server. As far as
I've seen, running an asyncio server requires
...
loop.run_forever()
...
And cmd.Cmd.cmdloop() is a blocking loop, so I'm not able to call them
sequentially. Is there a way to get the cmdloop to run asynchronously? Or a
way to call asyncio.streams.start_server from the cmdloop and actually have it
run continuously? I've tried a few things but nothing has been successful. I
should mention that by itself, the server functions.
For brevity, I'll try to keep the code to what is relevant.
class MyServer:
...
def start():
server = asyncio.async(
asyncio.streams.start_server(
self.accept_client,
host=self.ip,
port=self.port,
loop=self.loop
)
)
return server
...
class MyMenu(cmd.Cmd):
def __init__(self, loop):
cmd.Cmd.__init__(self)
...
do_serve(self, **kwargs):
server = MyServer(self.loop, **kwargs)
instance = server.start()
if __name__ == '__main__':
loop = asyncio.get_event_loop()
menu = MyMenu(loop)
menu.cmdloop()
Calling loop.run_forever() at any point breaks the menu functionality. Any
help would be greatly appreciated.
