Constants

const (
	// Bits or'ed together to control what's printed. There is no control over the
	// order they appear (the order listed here) or the format they present (as
	// described in the comments).  A colon appears after these items:
	//	2009/01/23 01:23:23.123123 /a/b/c/d.go:23: message
	Ldate         = 1 << iota     // the date: 2009/01/23
	Ltime                         // the time: 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
	LstdFlags     = Ldate | Ltime // initial values for the standard logger
)

These flags define which text to prefix to each log entry generated by the Logger.

Types

type Logger

type Logger struct {
	// contains filtered or unexported fields
}

A Logger represents an active logging object that generates lines of output to an io.Writer. Each logging operation makes a single call to the Writer's Write method. A Logger can be used simultaneously from multiple goroutines; it guarantees to serialize access to the Writer.

func New

func New(out io.Writer, prefix string, flag int) *Logger

New creates a new Logger. The out variable sets the destination to which log data will be written. The prefix appears at the beginning of each generated log line. The flag argument defines the logging properties.

func NewFileLogger

func NewFileLogger(path string, flag int) (*Logger, error)

NewFileLogger create a new Logger which output to a file specified

func NewRollFileLogger

func NewRollFileLogger(path string, maxsize uint, flag int) (*Logger, error)

NewRollFileLogger create a new Logger which output to a file specified path, and roll at specified size

func (*Logger) Debug

func (l *Logger) Debug(s string, v ...interface{}) error
