Nested ArgGroups?

[Masber]

Hi, I am using clap to build a CLI, one option is to get multiple entries through the date range or get a single entry by name, something like

mycli get --since 2023-01-01 --until 2023-10-01 # get all records created between those dates. Both params since and until must be provided

or

mycli get --name abc123 # get single entry with name 'abc123'

The issue is that I need to tell clap only one option is possible (either a combination of since and until or name), I tried creating 2 argroups nested, one to make sure both since and until are provided toghether and the second to make sure either dates or name is provided

    let cli_root = Command::new("mycli")
        .arg_required_else_help(true)
        .subcommand(
            Command::new("get")
                .arg(arg!(-s --since <DATE> "since"))
                .arg(arg!(-u --until <DATE> "until"))
                .arg(arg!(-n --name <NAME> "name"))
                .groups([
                    ArgGroup::new("since_and_until")
                        .args(["since", "until"])
                        .required(true),
                    ArgGroup::new("since_and_until_or_name").args(["since_and_until", "name"]),
                ]),
        )
        .get_matches();

But this breaks because apparently I can't use since_and_until agrgroup as an argument of another arggroup

thread 'main' panicked at 'Command get: Argument group 'since_and_until_or_name' contains non-existent argument 'since_and_until'', /home/xxxxx/.cargo/registry/src/index.crates.io-6f17d22bba15001f/clap-4.0.32/src/builder/debug_asserts.rs:309:13
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Any idea how to achieve the functionality I am looking for?

There are other problems with nested arg groups, see #4697.

In this case,instead of using an arg group to make the two options mutually exclusive, I'd recommend having name .conflicts_with("since_and_until)

Awesome!
I leave the solution here in case it is useful to someone else

    let cli_root = Command::new("mycli")
        .arg_required_else_help(true)
        .subcommand(
            Command::new("get")
                .arg(arg!(-s --since <DATE> "since"))
                .arg(arg!(-u --until <DATE> "until"))
                .arg(arg!(-n --name <NAME> "name"))
                .group(
                    ArgGroup::new("since_and_until")
                        .args(["since", "until"])
                        .multiple(true)
                        .requires_all(["since", "until"])
                        .conflicts_with("name"),
                ),
        )
        .get_matches();
