Install

The own developer should include on its program a way to manage extra files related to his project, instead of to be managed by another person (the package's maintainer into an operating system).

Here you have a simple way for the developer and easy to integrate in whatever system, with the advantage of be cross-platform. You only have to add code in functions Install, Remove, and Purge.

If you use Gowizard: gowizard -installer
Else, use this template in "<Go project>/Installer/install.go"

// Installer manages files related to the system.
//
// During the development, it could be used the command:
//
// sudo env PATH=$PATH GOPATH=$GOPATH go run install.go <flag...>
package main

import (
	"flag"
	"log"
	"os"
	//"runtime"
)

func Install() {
	
}

func Remove() {
	// Remove binary files.
}

func Purge() {
	Remove()
	// Remove config files, directories, etc.
}

// * * *

func init() {
	log.SetFlags(0)
	log.SetPrefix("ERROR: ")

	/* If a system has not been implemented on this manager, use:
	if runtime.GOOS == "windows" {
		log.Fatal("TODO: handle Windows")
	}*/
	if os.Getuid() != 0 {
		log.Fatal("you have to be root")
	}
}

func main() {
	install := flag.Bool("i", false, "install")
	remove := flag.Bool("r", false, "remove")
	purge := flag.Bool("p", false, "purge")

	flag.Parse()
	if flag.NFlag() == 0 {
		flag.PrintDefaults()
		os.Exit(2)
	}

	if *purge {
		Purge()
	} else if *remove {
		Remove()
	}
	if *install {
		Install()
	}
