...is a simple file based queue written in Ruby that uses the Ruby File class in standard library to push and pop items into a queue. It's not web scale but is nice for lightweight async queuing apps.

gem install filequeue

queue = FileQueue.new 'queue_party.txt'

queue.push "an item"
  => true
  
queue.pop
  => "an item"
