elevator

A golang library for requesting self-sudo.

Simply put, the idea is in the runtime, if the process is not started with superuser permissions, request them and then restart the application. The only rule is, this libraries CheckAndRequestElevation() function MUST be called as the first thing before the main application loads.

To supply the sudo username and password during development locally, just use the environment variables defined as,

ELEVATOR_SUDO_PASSWORD=12341234

As you should already know, what i described a moment ago is a terrible idea, and you should never do it. But, if you feel like not entering the password again and again on every restart while debugging your application, it's actually a quite useful tool. Maybe I'll provide more elegant ways of supplying a default password and username in future.

Installation

Just as any other go package, you can get it with go get

go get -u github.com/gokaykucuk/elevator

Example

package main

import (
	"github.com/gokaykucuk/elevator"
	"gitlab.com/..."
)

var (
	version   = "No version provided"
	commit    = "No commit provided"
	buildTime = "No build timestamp provided"
)

func main() {
	elevator.CheckAndRequestElevation()
	cmd.SetVersion(&cmd.Version{
		Version:   version,
		Commit:    commit,  
		BuildTime: buildTime,
	})
	cmd.Execute()
}

Contributing

You can create a PR and as long as it makes sense, and doesn't enlarge the scope of the project by 2, it'll be merged.

Testing

Currently there are no real tests because i don't have a good idea how to write them. If you have any good ideas please open a pull request.

TODO

• Make it windows compatibale?
• Make another function which will only check but not ask for permissions
