Hi, All.
Can anybody tell me how to implement kind of a timer in Ruby, similar to
the following one from Java?
timer = new Timer( 200, handler ); // call handler each 200 milliseconds
Thank you,

Here's a simple one
#!/bin/env ruby
require 'monitor'
class Timer
def initialize(interval, &handler)
raise ArgumentError, "Illegal interval" if interval < 0
extend MonitorMixin
@run = true
@th = Thread.new do
t = Time.now
while run?
t += interval
(sleep(t - Time.now) rescue nil) and
handler.call rescue nil
end
end
end
def stop
synchronize do
@run = false
end
@th.join
end
private
def run?
synchronize do
@run
end
end
end
t = Timer.new(1) do
puts "tick #{Time.now.to_f}"
# random sleep to show slot stability
sleep((5 + rand(10))/10.0)
end
sleep 10
t.stop

If your handler is short and you don't care too much about accuracy:
Thread.new { loop { handler; sleep 0.2 } }

This is what I use:
http://redshift.sourceforge.net/timer/timer.rb
It's pretty simple, and it corrects for the time taken by the handler.
