Re: [Factor-talk] Timers & Deployed Apps

[John B. <mr...@gm...>]

Your ``[ t ] loop`` is a busy loop that will suck 100% CPU.

The problem you have is that a timer starts a new thread, and you want to
wait forever just sleep the main thread?

    start-looping-timer 1 year sleep

I'm not sure if we have a way to wait for an existing thread to exit, but
if we did, it would be something like:

    start-looping-timer thread>> wait-for-thread

If you have trouble seeing the output of your timer, that is because the
timer thread is created knowing only about the global namespace, so if you
want to output to the stream you started it from:

    : start-looping-timer ( -- timer )
        output-stream get '[
            _ [ "Inside Loop" . ] with-output-stream*
        ] 2 seconds every ;

Hope that helps!
