spinner

type Spinner ¶

type Spinner struct {
	// contains filtered or unexported fields
}

Spinner animates a labeled spinner on os.Stderr while a blocking operation runs elsewhere. Call Start to begin animating, then Stop once the operation finishes; Stop clears the spinner's line.

If os.Stderr isn't a terminal, Start instead prints the description once as a plain line, since an animated spinner would be meaningless in redirected or logged output; Stop is then a no-op.

func New(description string) *Spinner

func (s *Spinner) Start()

func (s *Spinner) Stop()
