I'm writing a small ruby daemon that I am hoping will do the following:

• Check if a specific directory has files (in this case, .yml files)
• If so, take the first file (numerically sorted preferrably), and parse into a hash
• Do a 'yield', with this hash as the argument

What I have right now is like:

loop do
    get_next_in_queue { |s| THINGS }
end

def get_next_in_queue
  queue_dir = Dir[File.dirname(__FILE__)+'/../queue']
  info = YAML::load_file(queue_dir[0]) #not sure if this works or not
  yield info
end

I'd like to make the yield conditional if possible, so it only happens if a file is actually found. Thanks!
