periodicity¶ ↑

• github.com/vrinek/periodicity

Helps calculate the next run for schedulers using a human readable syntax.

period = Period.new(Time.now).every(2).hours.at(20).from(10).to(15)

means: every 2 hours at :20 from 10:00 to 15:00 (10:20, 12:20, 14:20)

period.next_run # returns the next calculated time as a Time object

Period.new.every(:half).hour # every 30 minutes
Period.new.every.week # every week
Period.new.every(5).seconds # every 5 seconds

• active support (not sure about the exact version yet)

• gem sources -a gems.github.com

• sudo gem install vrinek-periodicity

• add something like “every minute from 20:00 to 21:00 and from 02:00 to 03:00”
