Types

type DbPrinter

type DbPrinter interface {
	DbPrintf(format string, args ...interface{}) (int, error)
	DbPrint(args ...interface{}) (int, error)
	DbPrintln(args ...interface{}) (int, error)
}

type Fprinter

type Fprinter interface {
	Fprintf(w io.Writer, format string, args ...interface{}) (int, error)
	Fprint(w io.Writer, args ...interface{}) (int, error)
	Fprintln(w io.Writer, args ...interface{}) (int, error)
}

type NormalPrinter

type NormalPrinter interface {
	Printf(format string, args ...interface{}) (int, error)
	Print(args ...interface{}) (int, error)
	Println(args ...interface{}) (int, error)
}

type Printer

type Printer interface {
	NormalPrinter
	Fprinter
	Sprinter
	DbPrinter
	SetWriter(w io.Writer)
	SetDbWriter(w io.Writer)
	SetPrefix(prefix []byte)
	SetSuffix(suffix []byte)
}

Printer implements common printer functionality. It provides Print, Println, and Printf to os.Stdout as well as the more general FPrint, etc methods for writing to a specified io.Writer. In addition, the standard Sprint methods are available.

For convenience, a DbPrinter is provided through the methods DbPrint, DbPrintln, and DbPrintf. These 'debug' printer functions print to os.Stderr by default and wrap the output in given ANSI codes.

func NewPrinter

func NewPrinter() Printer

func NewPrinterWithOptions

func NewPrinterWithOptions(w io.Writer, db io.Writer, prefix, dbColor, suffix []byte) Printer

type Sprinter

type Sprinter interface {
	Sprintf(format string, args ...interface{}) string
	Sprint(args ...interface{}) string
	Sprintln(args ...interface{}) string
}
