pwnlog

Dead-simple, leveled-logging in Golang, pwn style. Colors and message prefixes are as the universe intended them to be:

   debug    -> [*] debugging text
   info     -> [+] info text
   warning  -> [-] warning text
   error    -> [!] error text
   fatal    -> [!!] fatal error text (followed by death of program)

Example usage:

    logger := pwnlog.New(pwnlog.DebugLevel)
    logger.Debug("this is debug output!")

    logger.SetLevel(pwnlog.InfoLevel)
    logger.Debug("you should NOT see this debug output")
    logger.Info("changed log level to %s", "info")
    logger.Warning("warning: error code %d", 42)
    logger.Error("ERROR!")

    // goodbye program
    logger.Fatal("F A T A L")

which produces the following:
