func DuplicateReader(reader systemio.Reader, errorCallback func(error)) (systemio.Reader, systemio.Reader)

DuplicateReader copies reads from a single io.Reader into a pair of io.Readers

It is the io.Reader analogue of an io.MultiWriter

func NewContinuousReader(reader systemio.Reader) systemio.Reader

NewContinuousReader creates a new ContinuousReader by wrapping an existing io.Reader

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

BellSkipper is a custom WriteCloser that skips `Bell` characters

Used to prevent promptui making sounds when a button is pressed

func NewBellSkipper(baseOutput systemio.WriteCloser) *BellSkipper

NewBellSkipper creates a new BellSkipper WriteCloser

func (skipper *BellSkipper) Close() error

Close closes the data stream

func (skipper *BellSkipper) Write(b []byte) (int, error)

Write writes len(p) bytes from p to the underlying data stream.

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

ContinuousReader is an io.Reader that wraps another reader and ignores io.EOF markers

This can be useful if you want to continue reading from a buffered reader after the buffer has been exhausted, for example

func (reader ContinuousReader) Read(p []byte) (int, error)

NewContinuousReader creates a new ContinuousReader by wrapping an existing io.Reader

Read reads up to len(p) bytes into p. If an io.EOF error is returned by the underlying reader, it is silently ignored.

type ErrorReader struct {
}

func NewErrorReader() *ErrorReader

func (errorWriter *ErrorReader) Read(p []byte) (int, error)
