Overview ¶
Package log provides functions for pretty print
Patterns of functions print:
- Print(), Printf(), Println(): (?time) msg
- Info(), Infof(), Infoln(): (?time) [INFO] msg
- Warn(), Warnf(), Warnln(): (?time) [WARN] warning
- Error(), Errorf(), Errorln(): (?time) [ERR] (?file:line) error
- Fatal(), Fatalf(), Fatalln(): (?time) [FATAL] (?file:line) error
Time pattern: MM.dd.yyyy hh:mm:ss (01.30.2018 05:5:59)

Constants ¶
const (
DefaultTimeLayout = "01.02.2006 15:04:05"
)
Variables ¶
var ShowTime = PrintTime
ShowTime sets printTime Time isn't printed by default
It was left for backwards compatibility
Functions ¶
func ChangeOutput ¶ added in v1.6.0
ChangeOutput changes Logger.output writer. Default Logger.output is github.com/fatih/color.Output
func ChangeTimeLayout ¶ added in v1.6.0
func ChangeTimeLayout(layout string)
ChangeTimeLayout changes Logger.timeLayout Default Logger.timeLayout is DefaultTimeLayout
func Error ¶
func Error(v ...interface{})
Error prints error Output pattern: (?time) [ERR] (?file:line) error
func Errorf ¶
func Errorf(format string, v ...interface{})
