mp command line utility is like curl or ncat for Message Ports (and ZeroMQ connections in general). It's a convenient way to experiment with different kinds of inter-process messaging patterns without having to write any code.
Here's an example of request/reply messaging:
First we open a reply socket on port 2000
$ mp reply 2000 - started reply socket on port 2000 - waiting for request
Lines beginning with a
- are log messages from the system. Now let's open another terminal and start a request socket connected to the same port.
$ mp request 2000 - started request socket on port 2000 <
When you see a
< that means that
mp is waiting for you to type a message that will transmitted to the other end of the connection. Type anything and press enter.
$ mp request 2000 - started reply socket on port 2000 < sup? - request sent - waiting for reply
Now switch back to the reply terminal and you should see
$ mp reply 2000 - started reply socket on port 2000 - waiting for request - request received: > sup? <
Type a response and switch back to the other terminal
$ mp request 2000 - started reply socket on port 2000 > sup? - message sent, waiting for response - reply received: > nm, u? <
