QuickStart

Enable your App to Self Update

	var updater = &selfupdate.Updater{
		CurrentVersion: version,
		ApiURL:         "http://updates.yourdomain.com/",
		BinURL:         "http://updates.yourdomain.com/",
		DiffURL:        "http://updates.yourdomain.com/",
		Dir:            "update/",
		CmdName:        "myapp", // app name
	}
	
	if updater != nil {
		// check if an update is available first
		new_version, err := updater.HasUpdate()
		
		if new_version != "" {
			fmt.Printf("Upgrading to v%s\n", new_version)
			go updater.BackgroundRun()
		}
	}

Push Out and Update

go-selfupdate myapp 1.2

This will create a folder in your project called, public you can then rsync or transfer this to your webserver or S3.

If you are cross compiling you can specify a directory:

go-selfupdate /tmp/mybinares/ 1.2

The directory should contain files with the name, $GOOS-$ARCH. Example:

windows-386
darwin-amd64
linux-arm

If you are using goxc you can output the files with this naming format by specifying this config:

"OutPath": "{{.Dest}}{{.PS}}{{.Version}}{{.PS}}{{.Os}}-{{.Arch}}",
