Types

type Tailer

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

Tailer scans a file for newly appended lines and returns them.

func New

func New(filename string) (*Tailer, error)

New creates a new Tailer object. It's the caller's responsibility to ensure the filename is correct. We don't check the file existence here because we have to tolerate log file rotation.

func (*Tailer) Close

func (t *Tailer) Close()

Close closes the Tailer object and release all resources.

func (*Tailer) Scan

func (t *Tailer) Scan() bool

Scan scans the file for new lines. See bufio.Scanner.Scan() for more details.

func (*Tailer) Text

func (t *Tailer) Text() string

Text returns the most recent line by a call of Scan from the file. See bufio.Scanner.Text() for more details.
