Question

Reclarification on the original question. I need a loop that will run in ruby and allow me to enter the commmand stop into the console (using gets perhaps) and then the loop will stop.

Cheers

I think you could use something like this:

# Initialize the input queue. This is where the user-created info will be stored
$QUEUE = []
def pending
  old = $QUEUE
  $QUEUE = []
  old
end

t = Thread.new do
  loop do
    # Ask the user for something
    print "Enter info here: "
    # Read information in
    $QUEUE << gets.chomp
  end
end

# Example code utilizing this; you can do whatever you like with the queue
2.times do
  sleep 5
  # Print the list out
  puts "\nYou entered: \n" << pending.join("\n")
end
