SAFAC (Simple Audio File Alarm Clock)

On friday, January 31st, I arrived in Brussels and accidentally locked myself out of my phone by entering three wrong PINs. Because I could not eject the SIM card to use my phone in a SIM-less mode, I could no longer set an alarm, and had to improvise.

I ended up writing this script to wake me up by playing specific audio files at a specific time.

alarm-clock.rb

#!/usr/bin/env ruby

require 'time'

def play
  files = Dir['Music/iTunes/iTunes Media/Music/Air/Le Voyage Dans La Lune/*.m4a'].sort
  files.each do |af|
    res = system('afplay', af)
    break if !res
  end
end

def wait_for(time)
  delay_in_s = (time - Time.now).to_i

  h, m, s = delay_in_s/60/60, (delay_in_s/60 % 60), (delay_in_s % 60)
  puts "Sleeping for #{delay_in_s} seconds (#{h}h #{m}min #{s}s)"

  sleep(delay_in_s)
end

wait_for(Time.parse('9:00:00'))
play
