Free Non Strict Options for a Command

[kudla]

Hi!
Please how could the flags be defined for the app level. Yet for the command level to let provide any flag without strict advance definition.

So that the application options would be available by name and the command options would be available as raw slice separated of command arguments. Something like this?

&cli.App{
		Name:  "app",
		Flags: []cli.Flag{
			&cli.StringFlag{
				Name:    "appOption",
				Aliases: []string{"o"},
			},
		},
		Commands: []*cli.Command{
			{
				Name:      "task",
				Action:    func(cCtx *cli.Context) error {
                                    appOption := cCtx.String("appOption")
                                    comOptions := cCtx.RestOfOptions()
                                    comArgs := cCtx.Args().Slice()
                                    return nil
                                },
			},
		},
	}

app -o app-level-options task --what ever -bc task-arguments next

Thx.

@kudla You can try setting the Command.SkipFlagParsing to true https://github.com/urfave/cli/blob/v2-maint/command.go#L45 This will allow you to get all the rest of the options in cCtx.Args().

That's great . Thank you @dearchap
What about partial definition ? E.g. some specific options would adjust the behavior of application it self yet all the rest options would be fed as is to a downstream application.

@kudla There is no support for that in the urfave/cli library. Its either all or nothing. Anything else you have to implement yourself.

Thanks @dearchap. I wen exactly the same direction
