LastLogLines returns the last n log lines from the buffer.

func (*Buffer) Listen ¶

func (buff *Buffer) Listen(cb func(s string)) *Listener

Listen to any Write() events by calling the specificed callback function. Note the callbacks are called synchronously with the Write() call, so care must be taken to not block for a significant amount of time.

The listener should be closed by calling its Close() method once it's no longer needed.

func (*Buffer) Write ¶

func (buff *Buffer) Write(b []byte) (int, error)

func (*Listener) Close ¶

func (l *Listener) Close()
