em-timers

helper methods for timers in EventMachine

examples:

# Once per hour, starting now. Note the :now symbol must be passed for your block to be called immediately.
EM::Timers.do_hourly(:starting => :now) { puts "drink a beer" }

# Once per day, starting in 1 day.
EM::Timers.do_daily { puts "take a shower" }

# Once per week, starting in 10 hours
EM::Timers.do_weekly(:starting => 10.hours.from_now) { puts "take out the garbage" }

# Once per month, starting at this time tomorrow.
EM::Timers.do_monthly(:starting => 1.day.from_now) { puts "pay the bills" }

# Or you can simply pass a number of seconds til starting
EM::Timers.do_monthly(:starting => 2592000) { puts "pay the bills, in seconds!" }

# Leveraging the Chronic time parsing library. em-timers knows if you have required 
# Chronic and uses it to parse strings if you have. Otherwise, it uses Time.parse.
#
# Every 2 hours, starting next Tuesday at 9AM.
require 'chronic'
EM::Timers.do(:every => 2.hours, :starting => 'next tuesday at 9am') { puts "go pee" }

# You can add up units of time as well
EM::Timers.do(:every => 1.minutes + 3.seconds) { puts "hi!" }

# You can list and cancel timers, too
EM::Timers.list.each { |timer|
  timer.cancel
}
