go-rpm

A native implementation of the RPM file specification in Go.

$ go get github.com/cavaliercoder/go-rpm

The go-rpm package aims to enable cross-platform tooling for yum/dnf/rpm written in Go (E.g. y10k).

Initial goals include like-for-like implementation of existing rpm ecosystem features such as:

Reading of modern and legacy rpm package file formats
Reading, creating and updating modern and legacy yum repository metadata
Reading of the rpm database

package main

import (
	"fmt"
	"github.com/cavaliercoder/go-rpm"
)

func main() {
	p, err := rpm.OpenPackageFile("golang-1.6.3-2.el7.rpm")
	if err != nil {
		panic(err)
	}

	fmt.Printf("Loaded package: %v - %s\n", p, p.Summary())

	// Output: golang-0:1.6.3-2.el7.x86_64 - The Go Programming Language
}

Tools

This package also includes two tools rpmdump and rpminfo.

The code for both tools demonstrates some use-cases of this package. They are both also useful for interrogating RPM packages on any platform.
