Ok, since the original post migh just appear in a month's time, lets
rephrase the question:

I'm building a set of tools for build and test management (yes, yes, it
will do DamagaControl's work and yes, yes it will be released...and yes,
this is code that is used in real-life projects - it's all so close to
public alpha status).
Now, I can leave scheduling to cron (or at/schtasks), but it would be
nice to provide an interface so that scheduling can be set in the
application via some administration console.
Behind the scenes cron manipulation is too flaky for my tastes (and for
windows I would need a separate implementation).
So, is there a library that will give me timers, a nice way to configure
them and a nice event driven interface?
Cheers,
V.-

I've wanted this myself. I wonder if we could get it down to Ruby
Quiz size...

I'm not sure about this. EventMachine seems geared towards networking.
I just want a class that will tick away on it's own thread and fire
events at designated time points.
My requirements include firing at intervals (every thirty minutes, every
two days), once (in thirty minutes, on 1/1/2007 at 0:00 etc.) and I
would like to have named events if possible.
Getting the events should be as simple as observing the timer.
So will anybody save me the work or do I have to code the beast?
Cheers,
V.-

I have nothing worthwhile to add, other then that I've also definitely
wanted something like this. rubyquiz?

Ara, you just plain rock.

My biggest request: a sane way (read: not-cron-like) to schedule
events.

How about stealing from schtasks
(http://www.microsoft.com/resources/d...spx?mfr=true)?
(ducks away and hides)
It doesn't have to be so convoluted.

Define the task like this

class ScheduledTask
attr_reader :name,:schedule,:schedule_params
end

Schedule is one of :minute, :hourly, :daily, :weekly, :monthly, :yearly

then according to schedule you have different options.
Universal options:
nce to generate the event only once. It's not there, then we get repeats.
:start_time to define when to start counting. If you leave it undefined
the timer starts immediately. If you define it, it should be in the future.
interval (after x minutes/hours/days/weeks/months/years an event will be
generated. if once is defined it runs once x /whatever/ after start_time)

An option valid for weekly and monthly can be :day, where you can
specify the day of the week (1-7) or month (1-31).

Would that be simple enough?
Cheers,
V.-

Try this in EventMachine:

require 'rubygems'
require 'eventmachine'

EventMachine.run {
EventMachine.add_periodic_timer(60) {
# The code in this block gets executed every sixty seconds
}
EventMachine.add_periodic_timer(3600) {
# The code in this block gets executed once an hour
}
}


You can read the timer definitions out of a config file, configure
them dynamically on the fly, or build them with a GUI.
