Installation
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
