subcommands and --version command

[Tobi-De]

Hi, how are you ? hope you doing great :)

Is this possible ? It seems the answer currently is no

@cappa.command(
    help="Enhance your Django developer experience: CLI and Guides for the Modern Django Developer.",
)
class Falco:
    subcommand: cappa.Subcommands[StartProject | UpdateProject | Fmt | SyncDotenv]
    version: Annotated[
        bool,
        cappa.Arg(
            short="-v",
            long="--version",
            help="print cli version",
        ),
    ] = False

I feel like the only option is to implement version as a subcommand

you can do cappa.parse/invoke(Falco, version='1.2.3') (or version=cappa.Arg('1.2.3', short="-v", long="--version", help="print cli version") if the default arg definition isn't what you want).

I believe you should also be able to define it on the class itself if you prefer, by setting action=ArgAction.version. Although i personally wouldn't, because it doesn't really make sense as a normal class field, given that it will always just be the default value if not used.
