Any way to handle none-option parameters?

[suntong]

Does CLI support handling none-option parameters?

For e.g., rsync takes an awful lot of options, but besides them, at the end of command line, there needs to be none-option parameters like source and optionally destination. Can CLI handle cases like this?

Thanks

Yes, it can. You can get the parameters by cli.Args(), e.g.

package main

import (
    "github.com/mkideal/cli"
)

type argT struct {
    cli.Helper
    Hello string `cli:"hello" usage:"world"`
}

func main() {
    cli.Run(new(argT), func(ctx *cli.Context) error {
        ctx.String("native args: %v\n", ctx.NativeArgs())
        ctx.String("args: %v\n", ctx.Args())
        return nil
    })
}

$ go run main.go --hello world p1 p2 p3
native args: [--hello world p1 p2 p3]
args: [p1 p2 p3]

Sorry mkideal I cannot connect the dots with my normal cli controlling structure, which looks like this:

var root = &cli.Command{
	Name: "dump",
	Desc: "dump assistant program",
	Text: "Swiss-army assistant toolkit",
	Argv: func() interface{} { return new(rootT) },
	Fn:   dump,

	NumOption: cli.AtLeast(1),
}

func main() {
	// default writer is os.Stdout
	if err := cli.Root(root).Run(os.Args[1:]); err != nil {
		fmt.Fprintln(os.Stderr, err)
	}
	fmt.Println("")
}

How to tweak above to accept none-option parameters?

The full code is at, https://gist.github.com/suntong/6658063cc0cf752f5d7ad5cc299f30bd
and when I run it, I got:

$ go run /tmp/dump.go aaa
ERR! command aaa not found

Please help. Thx.

Removing that NumOption: cli.AtLeast(1), won't help either.

[mkideal]

var root = &cli.Command{
	Name: "dump",
	Desc: "dump assistant program",
	Text: "Swiss-army assistant toolkit",
	Argv: func() interface{} { return new(rootT) },
	CanSubRoute: true, // NOTE: add this flag
	Fn:   dump,

	NumOption: cli.AtLeast(1),
}
