What would be the best way t

Answer 1

After reading this thread and others I decided to go with Luv lib. Here is my solution:

uv = require('luv') --luarocks install luv

function set_timeout(timeout, callback)
  local timer = uv.new_timer()
  local function ontimeout()
    uv.timer_stop(timer)
    uv.close(timer)
    callback()
  end
  uv.timer_start(timer, timeout, 0, ontimeout)
  return timer
end


set_timeout(1000, function() print('ok') end) -- time in ms

uv.run() --it will hold at this point until every timer have finished
