just released the “rufus-scheduler” 1.0.9 [gem].

It fixes a few bugs, mainly making jobs visible via get_job(job_id) even when they are right in the middle of execution.

It also introduces 4 new shorter aliases : “at”, “in”, “every” and “cron” (to “schedule_at”, “schedule_in”, “schedule_every” and “schedule” respectively) :

require 'rubygems'
require 'rufus/scheduler' # gem 'rufus-scheduler'

scheduler = Rufus::Scheduler.start_new

scheduler.in("3d") do
  regenerate_monthly_report()
end
  #
  # will call the regenerate_monthly_report method
  # in 3 days from now

scheduler.every "10m10s" do
  # every 10 minutes and 10 seconds
  check_score(favourite_team)
end

scheduler.cron "0 22 * * 1-5" do
  log.info "activating security system..."
  activate_security_system()
end

scheduler.at "Sun Oct 07 14:24:01 +0900 2009" do
  init_self_destruction_sequence()
end
