readercomp : Go package for comparing two finite io.Reader (e.g. files)

Why?

Comparing files (or more generally two finite io.Reader) is not as easy due to edge-cases like short reads and how errors (including EOF) are returned by calls to Read according to the interface specification.

This packages (tries) to deliver a solid implementation for these cases.

Install

go get github.com/hlubek/readercomp

Example

package main

import (
	"fmt"
	"log"
	"os"

	"github.com/hlubek/readercomp"
)

func main() {
	result, err := readercomp.FilesEqual(os.Args[1], os.Args[2])
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(result)
}
