Julia interface to ZMQ

A Julia interface to ZeroMQ

ZMQ.jl is a Julia interface to ZeroMQ, The Intelligent Transport Layer.

Installation

Pkg.add("ZMQ")

(This installs its own copy of the ZMQ libraries from the ZMQBuilder repository.)

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.
