Execute method at a certain time

Ruby
1

I have written a ruby script that needs to run all the time, then at a
certain time of day it needs to execute a specific method.

what is the best way of doing this ?

I could have the first script dump its data to a file all the time and
then have second script set up to run as a cron job but is there a way
to do this all in one script ?.

Thanks

How about something like this:

sleep(time_to_go - Time.now)

Of course this needs a little work to actually function but I would
think it
could work for you.

it needs to do stuff inbetween the scheduled event

Ah sorry, I misread needs to run all the time. Could you split that bit off
into a separate thread?

hmmm, i guess so, I will look into it, thanks for the suggestion

Maybe Rufus::Scheduler (

I am not sure, but the Timer class from facets might help you:

This looks like exactly what I need, basically cron inside ruby.

I am developing on windows at the moment and I am not sure how to
install this gem tho, does ruby gems work on windows ?.

any help appreciated.

Rubygems works fine for me on Windows. I do all my development at work
in
Windows. However you will occasionally run across a gem that needs to
compile something, that can be trickier.
