How to use the sys.inspect function in sys

global.debug = function(val) {
  var str;
  try {
    str = JSON.stringify(val, null, "  ");
  } catch (e) {
    str = sys.inspect(val, null, true);
  }
  sys.debug(str);
  process.exit();

}

exports.info = forLevels(['info', 'debug'], function (label, val) {
    if (val === undefined) {
        val = label;

    }
    if (typeof val !== 'string') {
        val = sys.inspect(val);
    }
    label ? sys.puts(magenta(label + ' ') + val): sys.puts(val);
});
