Like this
sleep(no_of_seconds)
Or you may pass other possible arguments like:
sleep(5.seconds)
sleep(5.minutes)
sleep(5.hours)
sleep(5.days)
This is an example of using sleep
with sidekiq
require 'sidekiq'
class PlainOldRuby
include Sidekiq::Worker
def perform(how_hard="super hard", how_long=10)
sleep how_long
puts "Workin' #{how_hard}"
end
end
sleep for 10 seconds and print out "Working super hard"
.
I find until
very useful with sleep. example:
> time = Time.now
> sleep 2.seconds until Time.now > time + 10.seconds # breaks when true
# or something like
> sleep 1.seconds until !req.loading # suggested by ohsully
sleep 6
will sleep for 6 seconds. For a longer duration, you can also use sleep(6.minutes)
or sleep(6.hours)
.
Use sleep like so:
sleep 2
That'll sleep for 2 seconds.
Be careful to give an argument. If you just run sleep
, the process will sleep forever. (This is useful when you want a thread to sleep until it's woken.)
Implementation of seconds/minutes/hours, which are rails methods. Note that implicit returns aren't needed, but they look cleaner, so I prefer them. I'm not sure Rails even has .days or if it goes further, but these are the ones I need.
class Integer
def seconds
return self
end
def minutes
return self * 60
end
def hours
return self * 3600
end
def days
return self * 86400
end
end
After this, you can do:
sleep 5.seconds
to sleep for 5 seconds. You can do sleep 5.minutes
to sleep for 5 min. You can do sleep 5.hours
to sleep for 5 hours. And finally, you can do sleep 5.days
to sleep for 5 days... You can add any method that return the value of self * (amount of seconds in that timeframe).
As an exercise, try implementing it for months!
