smaug

Package smaug implements a simple leveled logging package.

There are four logging levels: DEBUG, INFO, WARN and ERROR. And four corresponding loggers: Debug, Info, Warn and Error.

Each logger provides four logging methods: Dump, Print, Printf and Println.

Dump is a pretty printer.

Print, Printf and Println wrap the equivalent functions in the standard library log package.

// set our log level to INFO
smaug.Level = smaug.INFO

// logging through Debug will not create ouptut
smaug.Debug.Print("you won't see me")

// logging through Info, Warn and will create ouptut
smaug.Info.Print("you will see me")
smaug.Warn.Print("you will see me")
smaug.Error.Print("you will see me")

Package smaug also contains convenience methods for single error handling, where you're okay with panicing or exiting your process.

// this will call log.Fatal:
smaug.FatalIf(func () error {
	return errors.New("oh no!")
})

// this will call log.Panic:
smaug.PanicIf(func () error {
	return errors.New("oh no!")
})

Overall, no big shakes. Just a lighweight wrapper around other packages.
