DOT auto render script

dot_render.sh

function get_mtime {
  ls -l --time-style=+%s "${1?}" |  cut -d' ' -f6
}

function go_render {
  dotfile="$1"
  mtime=0
  while true;
  do
    newtime=$(get_mtime "$dotfile")
    test $mtime -ne $newtime && dot -O -Tpng $dotfile;
    mtime=$newtime
    sleep 1;
  done;
}

go_render myfile.dot &

Mac version of get_mtime:

function get_mtime {
  ls -l -T "${1?}" | cut -d' ' -f12
}

Mac version of go_render:

function go_render {
 dotfile="$1"
 mtime=0
 while true;
 do
   newtime=$(get_mtime "$dotfile")
   test $mtime != $newtime && dot -O -Tpng $dotfile;
   mtime=$newtime
   sleep 1;
 done;
}

NO TODOS LOS MAC SON IGUALES!!!

function get_mtime {
  ls -l -T "${1?}" | cut -d' ' -f10
}
