Overview

Go’s sirupsen/logrus is so handy that I’m writing this down as a memo.

When building tools in Go, there are times when I want to quickly change the level for debugging, and this is what I use for that.

It’s easier to understand by actually running it.

Go Playground

package main

import (
	log "github.com/sirupsen/logrus"
)

func main() {
	log.SetLevel(log.FatalLevel)

	log.Trace("1")
	log.Debug("2")
	log.Info("3")
	log.Warn("4")
	log.Error("5")
	log.Fatal("6")
	log.Panic("7")
}

That’s all.
I hope this is helpful.
