Functions

func Printf

func Printf(format string, v ...interface{})

Printf provides fmt.Printf like logging.

func Println

func Println(v ...interface{})

Println provides fmt.Println like logging.

func Reset

func Reset()

Reset resets all logging parameters.

func Scriptf

func Scriptf(format string, f func() []interface{})

Scriptf is similar with Scriptln, but for formatting output.

func Scriptln

func Scriptln(f func() []interface{})

Scriptln receives a function f which executes something and returns some values as a slice of empty interfaces. If logging is disabled, f is not executed.

func SetOutput

func SetOutput(w io.Writer)

SetOutput enables logging that writes out logs to w. Note that SetOutput works only once. To perform SetOutput again, it is necessary to call Reset before it.
