Support --all flag

[BusyJay]

It will be nice if cargo fmt --all will format all the projects in workspace just like cargo test -all will run all the tests in workspace.

Duplicate of #1244, which was already fixed.

[BusyJay]

Yes.

I can't get this to work, running cargo fmt --all I get the following:

cargo fmt --all

Unrecognized option: 'all'.
usage: cargo fmt [options]

Options:
-h, --help show this message
-q, --quiet no output printed to stdout
-v, --verbose use verbose output

This utility formats all bin and lib files of the current crate using rustfmt. Arguments after -- are passed to rustfmt.

Maybe I'm perhaps using it wrong? I'm trying to run this from within the root directory of a cargo virtual workspace.
Here's the link to my Cargo.toml I'm working with, if that's useful:

You probably want cargo fmt -- --all, I think.

[bjadamson]

Thank you @emilio I will give that a shot. Color me super surprised that's the syntax the cargo fmt team went with for this... I'm sure there's a good reason (;

I'm sure there's a good reason

I think it is because of Cargo, rather than rustfmt - arguments before the -- are passed to Cargo, arguments after the -- are passed to the plugin.

[BusyJay]

Are you using the latest version of rustfmt? I can run cargo fmt --all directly.
