klog

This is a simple leveled logging library (wrapper).

The usage is extremely simple, just set klog.DefaultLogger.Level with the desired level and call.

Sample program

package main

import (
	"flag"

	"github.com/kondukto-io/klog"
)

func main() {
	var debug bool
	flag.BoolVar(&debug, "debug", false, "debug")

	flag.Parse()

	if debug {
		klog.DefaultLogger.Level = klog.LevelDebug
	}

	klog.Println("regular print -- info")
	klog.Debug("this should print if debug flag is set")
	klog.Fatal("print fatal")
}

Output
