Overview

Package lineread reads lines from files. It's not fancy, but it got repetitive.

Functions

func File

func File(name string, fn func(line []byte) error) error

File opens name and calls fn for each line. It returns an error if the Open failed or once fn returns an error.

func Reader

func Reader(r io.Reader, fn func(line []byte) error) error

Reader calls fn for each line. If fn returns an error, Reader stops reading and returns that error. Reader may also return errors encountered reading and parsing from r. To stop reading early, use a sentinel "stop" error value and ignore it when returned from Reader.
