Subject: Re: Multiple workling instances

"I have modified my workling_client script to better handle multiple
worklings. This approach gives you full control over the workling
process names and pid files, which you can then use to cleanly manage
the worklings using God or Monit.

See below for my (admittedly hacky) solution:"

#!/usr/bin/env ruby
require 'rubygems'
require 'daemons'

# This is a bit hacky, but we don't have a clean way to hook into the
parsed
# options, as Daemons is managing these internally.
number = 0
for i in 0..ARGV.length
  if ARGV[i] == '--number'
    number = ARGV[i + 1]
    2.times {ARGV.delete_at(i)}
  end
end

puts "Workling Number: #{number}"

workling = File.join(File.dirname(__FILE__), '..', 'vendor',
'plugins', 'workling', 'script', 'listen.rb')
options = {
  :app_name   => "workling-#{number}-client",
  :ARGV       => ARGV,
  :dir_mode   => :normal,
  :dir        => File.join(File.dirname(__FILE__), '..', 'log'),
  :log_output => true,
  :multiple   => false,
  :backtrace  => true,
  :monitor    => false

}

Daemons.run(workling, options)
