Timeloop

Timeloop is a simple Ruby gem that provides loop with time interval inspired on 'every' method from whenever gem.

Installation

Add this line to your application's Gemfile:

gem 'timeloop'

And then execute:

$ bundle

Or install it yourself as:

$ gem install timeloop

Usage

Require gem in you Ruby file:

require 'timeloop'

Timeloop.every 10.seconds do
  puts '10 seconds delay'
end

# Result:

# 10 seconds delay
# 10 seconds delay
# 10 seconds delay
# ...

Timeloop.every 3.hours do
  Mail.deliver do
    from    'me@test.email'
    to      'you@test.email'
    subject '1 hour message'
    body    'Hi, you will get that message every hour. Be prepared!'
  end
end

Timeloop.every :minute do
  product = 2 * 2
  puts "and 2 * 2 is still #{product}"
end

# Result:

# and 2*2 is still 4
# and 2*2 is still 4
# and 2*2 is still 4
# ...

You can also specify how many times your block will be evaluated:

Timeloop.every 10.seconds, maximum: 4.times do |i|
 puts i
end

# Result:

# 0
# 1
# 2
# 3
# => 4

Timeloop.every 'second', maximum: 3 do |i|
 puts 'You will see me only 3 times.'
end

# Result:

# You will see me only 3 times.
# You will see me only 3 times.
# You will see me only 3 times.
# => 3

If you want to include the every method in your own classes simply include the Timeloop::Helper module.

class MyClass
  include Timeloop::Helper

  def doit
    every 10.seconds, max: 4 do |i|
      puts i
    end
  end
end
