Functions ¶

func Errorf ¶

func Errorf(format string, a ...interface{}) error

Errorf formats given arguments and returns it as error type.

func Fatal ¶

func Fatal(a ...interface{})

Fatal prints given arguments and finishes execution with exit status 1.

func Fatalf ¶

func Fatalf(format string, a ...interface{})

Fatalf prints a given format and finishes execution with exit status 1.

func Fatalln ¶

func Fatalln(a ...interface{})

Fatalln prints given arguments with newline and finishes execution with exit status 1.

func Fprint ¶

func Fprint(w io.Writer, a ...interface{}) (n int, err error)

Fprint prints given arguments to a given writer.

func Fprintf ¶

func Fprintf(w io.Writer, format string, a ...interface{}) (n int, err error)

Fprintf prints format to a given writer.

func Fprintln ¶

func Fprintln(w io.Writer, a ...interface{}) (n int, err error)

Fprintln prints given arguments to a given writer with newline.

func GetDefaultOutput ¶

func GetDefaultOutput() io.Writer

GetDefaultOutput returns pp's default output.

func Print ¶

func Print(a ...interface{}) (n int, err error)

Print prints given arguments.

func Printf ¶

func Printf(format string, a ...interface{}) (n int, err error)

Printf prints a given format.

func Println ¶

func Println(a ...interface{}) (n int, err error)

Println prints given arguments with newline.

func ResetColorScheme ¶

func ResetColorScheme()

ResetColorScheme resets colorscheme to default.

func ResetDefaultOutput ¶

func ResetDefaultOutput()

Change Print* functions' output to default one.

func SetColorScheme ¶

func SetColorScheme(scheme ColorScheme)

SetColorScheme takes a colorscheme used by all future Print calls.

func SetDefaultOutput ¶

func SetDefaultOutput(o io.Writer)

Change Print* functions' output to a given writer. For example, you can limit output by ENV.

func init() {
	if os.Getenv("DEBUG") == "" {
		pp.SetDefaultOutput(ioutil.Discard)
	}
}

func Sprint ¶

func Sprint(a ...interface{}) string

Sprint formats given arguemnts and returns the result as string.

func Sprintf ¶

func Sprintf(format string, a ...interface{}) string

Sprintf formats with pretty print and returns the result as string.

func Sprintln ¶

func Sprintln(a ...interface{}) string

Sprintln formats given arguemnts with newline and returns the result as string.

Types ¶

type ColorScheme ¶

type ColorScheme struct {
	Bool            uint16
	Integer         uint16
	Float           uint16
	String          uint16
