A simple wrapper for multiple logger instances.
example using https://github.com/sirupsen/logrus
stdOutLogger := logrus.New()
stdOutLogger.Formatter = &logrus.TextFormatter{DisableColors: false}
stdOutLogger.Level = logrus.WarnLevel
logf, _ := os.OpenFile("example.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0644)
fileLogger := logrus.New()
fileLogger.Out = logf
fileLogger.Formatter = &logrus.TextFormatter{DisableColors: true}
fileLogger.Level = logrus.DebugLevel
log = multilog.New(stdOutLogger, fileLogger)
log.Debug("debug message")
log.Warn("warn message")MIT
