"kumoly.io/lib/klog"
|
|
)
|
|
|
|
func main() {
|
|
Lklog.EVEL = Lerror | Ldebug | Lwarn | Linfo
|
|
klog.PROD = false
|
|
klog.Info("Hello, world.")
|
|
klog.Error("Error, world.")
|
|
|
|
// create sub logger
|
|
log := klog.Sub("me")
|
|
log.Warn("log with me")
|
|
|
|
// print fields
|
|
log.InfoF(klog.H{"Key":"value"}, "other ", "stuffs.")
|
|
|
|
// intercepting logs
|
|
p := log.GetPrinter()
|
|
log.SetPrinter(func(w io.Writer, d *Ldata, l *Logger) {
|
|
d.Message += " intercepted"
|
|
|
|
// NOT IN HERE
|
|
// as it will cause infinate loop
|
|
// p := log.GetPrinter()
|
|
