Functions

func AddFlags

func AddFlags(fs *flag.FlagSet)

AddFlags adds the flags used by this package to the given FlagSet. That's useful if working with a custom FlagSet. The init function of this package adds the flags to flag.CommandLine anyway. Thus, it's usually enough to call flag.Parse() to make the logging flags take effect.

func Debug

func Debug(args ...interface{})

Debug logs a message at level Debug on the standard logger.

func Debugf

func Debugf(format string, args ...interface{})

Debugf logs a message at level Debug on the standard logger.

func Debugln

func Debugln(args ...interface{})

Debugln logs a message at level Debug on the standard logger.

func Error

func Error(args ...interface{})

Error logs a message at level Error on the standard logger.

func Errorf

func Errorf(format string, args ...interface{})

Errorf logs a message at level Error on the standard logger.

func Errorln

func Errorln(args ...interface{})

Errorln logs a message at level Error on the standard logger.

func Fatal

func Fatal(args ...interface{})

Fatal logs a message at level Fatal on the standard logger.

func Fatalf

func Fatalf(format string, args ...interface{})

Fatalf logs a message at level Fatal on the standard logger.

func Fatalln

func Fatalln(args ...interface{})

Fatalln logs a message at level Fatal on the standard logger.

func Info

func Info(args ...interface{})

Info logs a message at level Info on the standard logger.

func Infof

func Infof(format string, args ...interface{})

Infof logs a message at level Info on the standard logger.

func Infoln

func Infoln(args ...interface{})

Infoln logs a message at level Info on the standard logger.

func NewErrorLogger

func NewErrorLogger() *log.Logger

NewErrorLogger returns a log.Logger that is meant to be used in the ErrorLog field of an http.Server to log HTTP server errors.

func Warn

func Warn(args ...interface{})

Warn logs a message at level Warn on the standard logger.

func Warnf

func Warnf(format string, args ...interface{})

Warnf logs a message at level Warn on the standard logger.

func Warnln

func Warnln(args ...interface{})

Warnln logs a message at level Warn on the standard logger.
