Logger is a simple cross platform Go logging library for Windows, Linux, FreeBSD, and macOS, it can log to the Windows event log, Linux/macOS syslog, and an io.Writer.

Set up the default logger to log the system log (event log or syslog):

package main

import (
  "github.com/bialas1993/log"
)

func main() {
	log.Debug("debug")
	log.With(log.LogFields{
		"asd":   "bsd",
		"lorem": "ipsum",
		"bang":  10,
		"struct": struct {
			A string
		}{"aaaaaa"},
	}).Info("info")
}
