Logging with color and format string
Usage
import (
"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()
p(w, d, l)
})
}
