Taking String Array Arguments

How To Take Array Of Strings As Argument?

I have this code:

// test.go
package main

import (
	"fmt"
	"github.com/alecthomas/kong"
)

type RunCmd struct {
	Target string `arg:"" name:"target" help:"Target To Run" type:"string"`
	Args   string `arg:"" name:"arguments" help:"Argument to pass to the program" type:"string"`
}

var cli struct {
	Run RunCmd `cmd:"" help:"Run an application from Remote."`
}

func (cmd *RunCmd) Run() (err error) {
	for i := 0; i < len(cmd.Args); i++ {
		fmt.Println(cmd.Args[i])
	}
	return nil
}

func main() {
	ctx := kong.Parse(&cli)
	// Call the Run() method of the selected parsed command.
	err := ctx.Run()
	ctx.FatalIfErrorf(err)
}

When I am Running go run ./test.go run myApp --start-dir ./ --title Noice, It shows me unknown flag error:

test: error: unknown flag --start-dir
exit status 1

and if instead i run this go run ./test.go run myApp start-dir ./ title Noice it works fine

start-dir
./
title
Noice

You probably want the passthrough tag as described here.

You also probably want to make arguments a slice:

Arguments []string `passthrough:""`

Adding passthrough didn't work but i tried adding -- before the list of arguments and it worked!, Like this:

go run ./test.go run myApp -- --start-dir ./ --title Noice
