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: // 2009/0123 01:23:23.123123 /a/b/c/d.go:23: message Ldate = 1 << iota // the date: 2009/0123 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 Lmodule // module name Llevel // level: 0(Debug), 1(Info), 2(Warn), 3(Error), 4(Panic), 5(Fatal) LstdFlags = Ldate | Ltime | Lmicroseconds // initial values for the standard logger Ldefault = Lmodule | Llevel | Lshortfile | LstdFlags )
These flags define which text to prefix to each log entry generated by the DefaultLogger.

Types ¶
type DefaultLogger ¶
type DefaultLogger struct { Level int // contains filtered or unexported fields }
A DefaultLogger 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 DefaultLogger 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) *DefaultLogger
New creates a new DefaultLogger. 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 (*DefaultLogger) Debug ¶
func (l *DefaultLogger) Debug(v ...interface{})
func (*DefaultLogger) Debugf ¶
func (l *DefaultLogger) Debugf(format string, v ...interface{})
func (*DefaultLogger) Error ¶
func (l *DefaultLogger) Error(v ...interface{})
func (*DefaultLogger) Errorf ¶
func (l *DefaultLogger) Errorf(format string, v ...interface{})
func (*DefaultLogger) Fatal ¶
func (l *DefaultLogger) Fatal(v ...interface{})
func (*DefaultLogger) Fatalf ¶
func (l *DefaultLogger) Fatalf(format string, v ...interface{})
Fatalf is equivalent to l.Printf() followed by a call to os.Exit(1).
func (*DefaultLogger) Fatalln ¶
func (l *DefaultLogger) Fatalln(v ...interface{})
Fatalln is equivalent to l.Println() followed by a call to os.Exit(1).
func (*DefaultLogger) Flags ¶
func (l *DefaultLogger) Flags() int
Flags returns the output flags for the logger.
func (*DefaultLogger) Info ¶
func (l *DefaultLogger) Info(v ...interface{})
func (*DefaultLogger) Infof ¶
func (l *DefaultLogger) Infof(format string, v ...interface{})
func (*DefaultLogger) Output ¶
Output writes the output for a logging event. The string s contains the text to print after the prefix specified by the flags of the DefaultLogger. A newline is appended if the last character of s is not already a newline. Calldepth is used to recover the PC and is provided for generality, although at the moment on all pre-defined paths it will be 2.
func (*DefaultLogger) Panic ¶
func (l *DefaultLogger) Panic(v ...interface{})
Panic is equivalent to l.Print() followed by a call to panic().
func (*DefaultLogger) Panicf ¶
func (l *DefaultLogger) Panicf(format string, v ...interface{})
Panicf is equivalent to l.Printf() followed by a call to panic().
func (*DefaultLogger) Panicln ¶
func (l *DefaultLogger) Panicln(v ...interface{})
Panicln is equivalent to l.Println() followed by a call to panic().
func (*DefaultLogger) Prefix ¶
func (l *DefaultLogger) Prefix() string
Prefix returns the output prefix for the logger.
func (*DefaultLogger) Print ¶
func (l *DefaultLogger) Print(v ...interface{})
Print calls l.Output to print to the logger. Arguments are handled in the manner of fmt.Print.
func (*DefaultLogger) Printf ¶
func (l *DefaultLogger) Printf(format string, v ...interface{})
Printf calls l.Output to print to the logger. Arguments are handled in the manner of fmt.Printf.
func (*DefaultLogger) Println ¶
func (l *DefaultLogger) Println(v ...interface{})
Println calls l.Output to print to the logger. Arguments are handled in the manner of fmt.Println.
func (*DefaultLogger) SetFlags ¶
func (l *DefaultLogger) SetFlags(flag int)
SetFlags sets the output flags for the logger.
func (*DefaultLogger) SetPrefix ¶
func (l *DefaultLogger) SetPrefix(prefix string)
SetPrefix sets the output prefix for the logger.
func (*DefaultLogger) SingleStack ¶
func (l *DefaultLogger) SingleStack(v ...interface{})
func (*DefaultLogger) Stack ¶
func (l *DefaultLogger) Stack(v ...interface{})
func (*DefaultLogger) Stat ¶
func (l *DefaultLogger) Stat() (stats []int64)
func (*DefaultLogger) Warn ¶
func (l *DefaultLogger) Warn(v ...interface{})
func (*DefaultLogger) Warnf ¶
func (l *DefaultLogger) Warnf(format string, v ...interface{})
type Logger ¶
type Logger interface { Debug(v ...interface{}) Debugf(format string, v ...interface{}) Info(v ...interface{}) Infof(format string, v ...interface{}) Warn(v ...interface{}) Warnf(format string, v ...interface{}) Errorf(format string, v ...interface{}) Error(v ...interface{}) }
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.
