Chapter 3. Getting started

The Hello World example creates a connection to the broker, sends a message containing a greeting to the examples queue, and receives it back. On success, it prints the received message to the console.

Change to the examples directory and run the helloworld.rb example.

cd /usr/share/proton/examples/ruby/
ruby helloworld.rb amqp://127.0.0.1 examples

$ cd /usr/share/proton/examples/ruby/
$ ruby helloworld.rb amqp://127.0.0.1 examples
Hello World!
