Nested yaml structures

[binwiederhier]

Howdy,

Thanks for urfave/cli! I've been using it for years in many projects. Great job!

I'd like to know if it is possible to represent something like this with the lib:

converters:
  - grafana:
      title: object.key
      message: object.nested.nested.key
  - github:
      title: object.key
      message: object.nested.nested.key

I tried fiddling with the Generic flag, without success. I'd be okay if this is only available via the yaml alt source.

Btw, do you have a Discord/chat where one could ask these questions? I couldn't find one.

Hi @binwiederhier
Of course you can make the yaml file like that.
But I'm not sure the object that has child hierarchy can become a list.
You can use leaf values as a list. So I think you need to remove the '-'.

anyway you can use the hierarchy like following.

"github.com/urfave/cli/v2"

func main() {
        flags := []cli.Flag{
		&cli.StringFlag{
			Name:  "config",
			Usage: "yaml config file name",
		},
		altsrc.NewStringFlag(
			&cli.StringFlag{
				Name:        "converters.github.title",
				Aliases:     []string{},
				Value:       "",
			},
		),
	}
        app := &cli.App{
		Flags:  flags,
		Before: altsrc.InitInputSourceWithContext(flags, altsrc.NewYamlSourceFromFlagFunc("config")),
		Action: func(ctx *cli.Context) error {
	                fmt.Println(ctx.String("converters.github.title"))
                        return nil
                },
	}
	fmt.Println(app.Run(os.Args))
}

@binwiederhier Yes there is a discord server called urfave/cli with channels for v1/v2/v3.
