A simple file based queue written in Ruby that uses the battle-tested Filelock gem 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"

See spec/filequeue_spec.rb for more usage details

FileQueue has the following class methods:

• push (alias <<)
• pop
• length
• empty?
• clear

Locking is delegated to the excellent Filelock gem. All of the Filelock's caveats apply.

• NFS is not supported

• Origially written by daddz and found in this gist.
