Overview

Example (Logall)

package main

import (
	"berty.tech/berty/v2/go/internal/logutil"
)

func main() {
	logger, cleanup, err := logutil.NewLogger("*", "light-console", "stdout")
	if err != nil {
		panic(err)
	}
	defer cleanup()

	logger.Debug("top debug")
	logger.Info("top info")
	logger.Warn("top warn")
	logger.Error("top error")

	logger.Named("foo").Debug("foo debug")
	logger.Named("foo").Info("foo info")
	logger.Named("foo").Warn("foo warn")
	logger.Named("foo").Error("foo error")

}

Output:

DEBUG	bty               	top debug
INFO 	bty               	top info
WARN 	bty               	top warn
