Installation

Install libzmq.

gem install zmq

If the gem installation complains that it cannot find libzmq or headers, simply pass the location of your libzmq installation to the gem install command:

gem install zmq -- --with-zmq-dir=/opt/local

On Windows add a parameter for the libs. For example:

gem install zmq -- --with-zmq-dir=c:/src/zeromq-4.3.2 --with-zmq-lib=c:/src/zeromq-4.3.2/src/.libs

Example

require "zmq"

context = ZMQ::Context.new(1)

puts "Opening connection for READ"
inbound = context.socket(ZMQ::UPSTREAM)
inbound.bind("tcp://127.0.0.1:9000")

outbound = context.socket(ZMQ::DOWNSTREAM)
outbound.connect("tcp://127.0.0.1:9000")
p outbound.send("Hello World!")
p outbound.send("QUIT")

loop do
  data = inbound.recv
  p data
  break if data == "QUIT"
end
