Julia interface to ZMQ

A Julia interface to ZeroMQ

ZMQ.jl is a [Julia] (http://julialang.org) interface to [ZeroMQ, The Intelligent Transport Layer] (http://zeromq.org).

ZMQ version 3 or later is required; ZMQ version 2 is not supported.

Installation

Pkg.add("ZMQ")

Install the ZeroMQ libraries for your OS using your favourite package manager.

Usage

using ZMQ

ctx=Context()
s1=Socket(ctx, REP)
s2=Socket(ctx, REQ)

ZMQ.bind(s1, "tcp://*:5555")
ZMQ.connect(s2, "tcp://localhost:5555")

ZMQ.send(s2, Message("test request"))
msg = ZMQ.recv(s1)
out=convert(IOStream, msg)
seek(out,0)
#read out::MemIO as usual, eg. read(out,...) or takebuf_string(out)
#or, conveniently, use unsafe_string(msg) to retrieve a string

ZMQ.send(s1, Message("test response"))
ZMQ.close(s1)
ZMQ.close(s2)
ZMQ.close(ctx)

Troubleshooting

If you are using Windows and get an error Provider PackageManager failed to satisfy dependency zmq, you may need to restart Julia and run Pkg.build("ZMQ") again. See issue #69 for more details.
