wirepickle 1.0.0

Effortless Python RPC with ZeroMQ

wirepickle

Effortless python remote procedure calling with pickle over ZeroMQ. Allows you to expose a single class instance as an API server over every transport layer that ZeroMQ provides.

Quick Setup

Install wirepickle using your favorite package manager:

$ pip install wirepickle

Server

Next, on your server, annotate the methods you want to expose with the @expose decorator:

from wirepickle.server import expose, Server

class Foo:
    @expose('bar')
    def bar(self):
        print('bar')
        return 0

    @expose('baz')
    def baz(self, arg1, kwarg1='baz'):
        print(kwarg1)
        return self.bar() + arg1

Note that you can return anything that can be pickled as a return value, and that stdout will be mirrored to the client.

Then, pass an instance of the class to the Server constructor to create the server. To start listening, call the Server#listen() method on the constructed server with a bind URI:

if __name__ == '__main__':
    instance = Foo()

    Server(instance).listen('tcp://*:12345')

Client

Simply pass a URI to connect to and start using the methods.

from wirepickle.client import Client

foo = Client('tcp://127.0.0.1:12345')

foo.bar()

If desired, you can pass a timeout kwarg to the Client constructor:

foo = Client('tcp://127.0.0.1:12345', timeout=1_000) # milliseconds
