How to forward args? (Like "$@" in bash)

[Boscop]

How can I forward args to a subcommand (e.g. cargo)?
(Like "$@" in bash)

[casey]

Do you want to forward a fixed number of arguments, or a variable number of arguments?

All arguments can be forwarded, even if variadic:

bar +b:
	echo {{b}}

foo +a: (bar a)

But there isn't a direct equivalent of $@.

@casey Thanks. +a works with forwarding, but then it requires at least one arg. How can I also accept zero args?

[casey]

If you give it the empty string as a default argument, it will accept zero args:

bar +b="":
	echo {{b}}

This is definitely somewhat cumbersome. I'm not sure why I didn't just give it this behavior to begin with, but at this point I think it would be reasonable to add * that accepts zero or more arguments, and evaluates to the empty string when no arguments are given.

[Boscop]

@casey I actually tried *a hoping that it would allow "zero or more" args. I think that would be the most intuitive.
(Well, even more intuitive would be to not distinguish between * and + at all.)

[casey]

Agreed! I just opened #633, to add * with that behavior. Although I'm not sure when it'll get done, since other projects are taking all my cycles.
