updater: golang library for self updating programs

Features

• update from repository (HTML index)
• Semantic Versioning support This repository is a golang library that provides an auto-updater embeddable in your go binary.

Updates are to be fetched from a repository. Currently only basic HTML indexes are supported, such as those generated by Sonatype Nexus.

Installation

You are free to go get the lib as any golang library but the prefered way to install it is using dep.

dep ensure -add github.com/fabienm/updater

var version = "1.0.1"

func main() {
	u:= updater.New(updater.Config{
		BinaryName: "mybinary",
		Repository:"http://example/nexus/content/repositories/releases",
	})
	build, _:= u.FindLatest()

	if build.NewerThan(version) {
		fmt.Printf("Do you want to update to %s? [Y/n]\n", build.Version)
		input:= "y"
		fmt.Scanln(&input)
		if strings.ToLower(input[0:0]) == "y" {
			u.UpdateTo(build)
			os.Exit(0)
		}
