= i_can_daemonize

== DESCRIPTION:

ICanDaemonize makes it dead simple to create daemons of your own.

== REQUIREMENTS:

* A Computer
* Ruby

== INSTALL:

* Get ICanDaemonize off github

== THE BASICS:

  require 'rubygems'
  require 'i_can_daemonize'
  class MyDaemonClass
    include ICanDaemonize
    
    daemonize do
      # your code here
    end
    
  end

Run your daemon

  ruby your_daemon_script start
  
ICD will create a log file in log/ called your_daemon_script.log as well as a pid file in log called your_daemon_script.pid

It will essentially run the block given to daemonize within a loop.

== USAGE:

The daemonize method accepts a number of options see ICanDaemonize::ClassMethods daemonize() for options

There are a number of other blocks you can define in your class as well, including:

  before do/end

  after do/end

  die_if do/end

  exit_if do/end

See ICanDaemonize docs for more info on these options.

Your daemon can be called with a number of options

      --loop-every SECONDS         How long to sleep between each loop
  -t, --ontop                      Stay on top (does not daemonize)
      --instances=NUM              Allow multiple instances to run simultaneously? 0 for infinite. default: 1
      --log-file=LOGFILE           Logfile to log to
      --pid-file=PIDFILE           Directory to put pidfile
  -h, --help                       Show this message

You can add your own command line options by using the 'arg' class macro.  
See http://www.ruby-doc.org/stdlib/libdoc/optparse/rdoc/classes/OptionParser.html for more info on OptionParser.
  
  arg('--scott-rocks', 'Does scott rock?') do |value|
    @scott_rocks = value
  end
  
== BUGS:

My method names may be too common to be included class methods

ICanDaemonize attempts to capture all STDOUT or STDERR and prepend that output with a timestamp and PID.
I don't like how this was implemented anyway. Feels dirty.
