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
	Lmsgprefix                // move the "prefix" from the beginning of the line to before the message
	Lfuncname
	LstdFlags = Ldate | Ltime // initial values for the standard logger
)

These flags define which text to prefix to each log entry generated by the Logger. Bits are or'ed together to control what's printed. With the exception of the Lmsgprefix flag, there is no control over the order they appear (the order listed here) or the format they present (as described in the comments). The prefix is followed by a colon only when Llongfile or Lshortfile is specified. 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
