whoami command

[yakuter]

Get the active username command.

[abdrd]

May I implement this one ?

[yakuter]

Of course. It is on you @betelgeuse-7

[abdrd]

Thanks!

[abdrd]

Is it okay if I don't use github.com/urfave/cli/v2 package ?

[abdrd]

I am planning to implement other commands, and I don't like to use an abstraction for such small applications.

[yakuter]

Well this cli package is the skeleton of our CLI application "gol". So I expect you to implement this feature just like the echo command. You don't need abstraction. You can just duplicate the command architecture from other commands

[abdrd]

I had implemented it like this:

const (
	_HELP = `Usage: whoami [OPTION]
Print  the  user name associated with the current effective user ID.  
Same as id -un.

	--help, -h 		display this help and exit
	--version, -v 	output version information and exit		
`
	_VERSION = "0.0.1"
	_CMDNAME = "whoami"
)

func whoami(args []string) error {
	argsLen := len(args)
	switch argsLen {
	case 1:
		// only program name
		u, err := user.Current()
		if err != nil {
			return err
		}
		fmt.Println(u.Username)
	case 2:
		arg := args[1]
		switch arg {
		case "--help", "-h":
			fmt.Print(_HELP)
		case "--version", "-v":
			fmt.Printf("whoami - version %s\n", _VERSION)
		default:
			return fmt.Errorf("unknown command '%s'; pass '--help', or '-h' for help information", arg)
		}
	default:
		return fmt.Errorf("excessive number of arguments (%d)", argsLen)
	}
	return nil
}

func Run(args []string) error {
	return whoami(args)
}

/// TESTS

OK then... Good luck

[abdrd]

You can deassign me

[yakuter]

@betelgeuse-7 I would like you to complete the PR if it is OK with you. You could have just used the lines you wrote with a command template like echo here

u, err := user.Current()
if err != nil {
	return err
}
fmt.Println(u.Username)

[yakuter]

Alright, I deassigned you.

Sorry for wasting your time. I hopped into this without actually reading the code-base.
Again, sorry...
