Golang implementation of parsing RPM packages

Go RPM Utils

go-rpmutils is a library written in go for parsing and extracting content from RPMs.

Overview

go-rpmutils provides a few interfaces for handling RPM packages. There is a highlevel Rpm struct that provides access to the RPM header and CPIO payload. The CPIO payload can be extracted to a filesystem location via the ExpandPayload function or through a Reader interface, similar to the tar implementation in the go standard library.

Example

// Opening a RPM file
f, err := os.Open("foo.rpm")
if err != nil {
    panic(err)
}
rpm, err := rpmutils.ReadRpm(f)
if err != nil {
    panic(err)
}
// Getting metadata
nevra, err := rpm.Header.GetNEVRA()
if err != nil {
    panic(err)
}
fmt.Println(nevra)
provides, err := rpm.Header.GetStrings(rpmutils.PROVIDENAME)
if err != nil {
    panic(err)
}
fmt.Println("Provides:")
for _, p := range provides {
    fmt.Println(p)
}
// Extracting payload
if err := rpm.ExpandPayload("destdir"); err != nil {
    panic(err)
}
