Introducing the Run Every gem

require 'run_every'

RunEvery.four.seconds {puts 'hello'}
#=> hello
#=> hello
#=> hello

RunEvery.new(seconds: 4) {puts 'hi'}
#=> hi
#=> hi
#=> hi

#RunEvery.two.minutes {puts 'hello'}

The Run Every gem is a simple timer with a code block. The interval can be set in seconds or minutes either using method chaining or through a hash passed into initialize(). The chaining method intervals include: one, two, three, four, five, ten, fifteen, twenty, twentyfive, thirty, forty, fifty.

a = '12'
RunEvery.new(seconds: 6) do 
  if a == '12' then
    puts '..'
  elsif a == '1' then
    puts 'we have a winner'
    Thread.stop
  else
    puts 'nothing to see here'
  end
end

a = 1
#=> we have a winner

2 things worth noting: 1) variable scope can extend to outside the block. 2) The thread can be stopped from within the block using Thread.stop
