Golang bindings for RAUC

This Go package provides bindings for RAUC.

For details on the properties and calling semantics, please refer to the DBus API documentation of the RAUC project.

Install

Install the package like this:

go get github.com/holoplot/go-rauc/rauc

And then use it in your source code.

import "github.com/holoplot/go-rauc/rauc"

Example

Below is an example to illustrate the usage of this package. Note that you will need to have a working RAUC installation, including a valid config and all.

package main

import (
	"log"
	"github.com/holoplot/go-rauc/rauc"
)

func main() {
	raucInstaller, err := rauc.InstallerNew()
	if err != nil {
		log.Fatal("Cannot create RaucInstaller")
	}

	operation, err := raucInstaller.GetOperation()
	if err != nil {
		log.Fatal("GetOperation() failed")
	}
	log.Printf("Operation: %s", operation)


	bootSlot, err := raucInstaller.GetBootSlot()
	if err != nil {
		log.Fatal("GetBootSlot() failed")
	}
	log.Printf("Boot slot: %s", bootSlot)

	slotStatus, err := raucInstaller.GetSlotStatus()
	if err != nil {
		log.Fatal("GetSlotStatus() failed")
	}

	for count, status := range slotStatus {
		log.Printf("status[%d]: %s", count, status.SlotName)

		for k, v := range status.Status {
			log.Printf("    %s: %s", k, v.String())
		}
	}

	variant, err := raucInstaller.GetVariant()
	if err != nil {
		log.Fatal("GetVariant() failed")
	}
	log.Printf("Variant: %s", variant)

	percentage, message, nestingDepth, err := raucInstaller.GetProgress()
	if err != nil {
		log.Fatal("GetProgress() failed", message)
	}
	log.Printf("Progress: percentage=%d, message=%s, nestingDepth=%d", percentage, message, nestingDepth)

	filename := "/path/to/update.raucb"
	compatible, version, err := raucInstaller.Info(filename)
	if err != nil {
		log.Fatal("Info() failed", err.Error())
	}
	log.Printf("Info(): compatible=%s, version=%s", compatible, version)

	err = raucInstaller.InstallBundle(filename, rauc.InstallBundleOptions{})
	if err != nil {
		log.Fatal("InstallBundle() failed: ", err.Error())
	}
}
