Rufus-Scheduler Running Only Once

Question

I am using Rufus Scheduler to run another Ruby script every two minutes. The script runs once, but never again. Is there an error in my code? HTOP shows that "launcher.rb" continues to exist as a process after the "script.rb" code runs once.

#launcher.rb

require "rubygems"
require "rufus-scheduler"

scheduler = Rufus::Scheduler.new    

scheduler.every("2m")do
    require "/home/pi/Bots/script.rb"
end

scheduler.join

Answer 1

You could try with

#launcher.rb

require "rubygems"
require "rufus-scheduler"

scheduler = Rufus::Scheduler.new

scheduler.every("2m")do
  #require "/home/pi/Bots/script.rb"
  load "/home/pi/Bots/script.rb"
end

scheduler.join

It may work ("may" because I don't know exactly what's in your script.rb). require will not load and run again whatever behind your "home/pi/Bots/script.rb" while load will load and run each time.

What happens with your current launcher is that require is called every 2 minutes, but only the first time does it load and run the script.rb.

Please note that the following might be better:

# script.rb

module MyBot
  def self.call
    # do the job...
  end
end


# launcher.rb

require 'rubygems'
require 'rufus-scheduler'
require '/home/pi/Bots/script.rb'

scheduler = Rufus::Scheduler.new

scheduler.every('2m') do
  MyBot.call
end

scheduler.join
