Constants

const (
	Ldate         = 1 << iota // the date in the local time zone: 2009/01/23
	Ltime                     // the time in the local time zone: 01:23:23
	Lmicroseconds             // microsecond resolution: 01:23:23.123123.  assumes Ltime.
	Llongfile                 // full file name and line number: /a/b/c/d.go:23
	Lshortfile                // final file name element and line number: d.go:23. overrides Llongfile
	Lutc                      // if Ldate or Ltime is set, use UTC rather than the local time zone

	LNoStackTrace // No Run runtime.Caller()  for getting Stack Trace info

	LstdFlags = Ldate | Ltime // initial values for the standard Logger
)

These flags define which text to prefix to each log entry generated by the LoggerI. Bits are or'ed together to control what's printed. For example, flags Ldate | Ltime (or LstdFlags) produce,

2009/01/23 01:23:23 message

while flags Ldate | Ltime | Lmicroseconds | Llongfile produce,

2009/01/23 01:23:23.123123 /a/b/c/d.go:23: message
