doing something each second

Hi,
is it possible to execute a block each second for let's say 8 hours a day?
Instead of using threads maybe. Something like this:

Time.each.second do {
stuff
}

Thanks

Cheers,

Chris

Off the top of my head, you can do something like:

while true
sleep 1
stuff
end

Off the top of my head, you can do something like:

while true
=A0sleep 1
=A0stuff
end

Note thought hat if stuff takes longer you will execute something with
1 second _pauses_ which is not the same as execute something each
second.

Kind regards

robert

There's no way to run something asynchronously every second or trigger
something to run asynchronously every second without a thread of some
kind or without interrupting the flow of the main thread. Why don't
you want to use a thread?

It could probably be done with a signal handler, but that's not the
kind of code anyone wants to maintain in its raw state. However this
does look like a nice idea for a thread abstraction...

Thanks to all of you. I actually started out using a thread but then got
into some trouble, which some people helped me to solve. I was just thinking
that there might be a way of using Time.second.each do {....} because I saw
5.times do {...}. That was just a "creative" conclusion.

You could do something like this with an asynchronous event framework like
EventMachine or Rev without using a thread, although if what you're trying
to do every second takes longer than a second you will likely get... strange
behavior.

Here's an example with Rev:

class MyTimer < Rev::TimerWatcher
def on_timer
do_something
end
end

watcher = MyTimer.new(1, true) # 1 second repeating
watcher.attach Rev::Loop.default

Rev::Loop.default.run
