slogger: simple go logger

This is a small go package that provides a few simple logging functions to aid in development. This package allows you to register a new logger very similar to how you would a standard go log.Logger, with the added ability to pass paremeters to configure a log color (using ANSI color codes) and some log prefixese.

)

func main() {
    // Declare some loggers
    infoLogger := slogger.New(os.Stdout, slogger.ANSIBlue, "info", log.Lshortfile+log.Ldate);
    errorLogger := slogger.New(os.Stderr, slogger.ANSIRed, "error", log.Lshortfile+log.Ldate);

    // Log some things
    infoLogger.Log("main", "Something worth noting happened", 2+4)
    errorLogger.Log("main", "Some horrible error happened", []int{3, 5, 7})
}
