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

func main() {
    f, err := os.Open("foo.rpm")
    if err != nil {
        panic(err)
    }

    // Parse the rpm
    rpm := rpmutils.ReadRpm(f)

    // Get the name, epoch, version, release, and arch
    nevra, err := rpm.Header.GetNEVRA()
    if err != nil {
        panic(err)
    }

    fmt.Printf("%s\n", nevra)

    // Reading the provides header
    provides, err := rpm.Header.GetStrings(rpmutils.PROVIDENAME)
    if err != nil {
        panic(err)
    }

    fmt.Printf("Provides:\n")
    for _, p := range provides {
        fmt.Printf("%s", p)
    }
}
