Execution of a resident script

[a455115]

I couldn't do something. Can you give a concrete example of how to put this sample code into a library, running as a resident script with 0 sleep time?

Code:

if not pirs then
  pirs = {
    { input = '1/1/1', output = '2/1/1' },
    { input = '1/1/2', output = '2/1/2' },
  }
end

now = os.time()
for _, pir in ipairs(pirs) do
  key = 'pir_timer_' .. pir.input
  delta = now - storage.get(key, 0)

  -- set output to 0% after 1 hour
  if delta > 60 * 60 then
    grp.checkwrite(pir.output, 0)
  -- set output to 20% after 30 minutes
  elseif delta > 30 * 60 then
    grp.checkwrite(pir.output, 20)
  end
