README

diff

diff is a Go package for comparing files and io.Readers.

Documentation

Overview

Package diff checks whether files and io.Readers have identical contents.

Index

• func Files(file1, file2 string) (different bool, err error)
• func Readers(r1, r2 io.Reader) (different bool, err error)

Functions

func Files

func Files(file1, file2 string) (different bool, err error)

Files compares the contents of file1 and file2. Files first compares file length before looking at the contents.

func Readers

func Readers(r1, r2 io.Reader) (different bool, err error)

Readers compares the contents of two io.Readers. The return value of different is true if and only if there are no errors in reading r1 and r2 (io.EOF excluded) and r1 and r2 are byte-for-byte identical.
