Does this work:
(setq format-all-formatters
'(("Rust" (rustfmt "--edition" "2021"))))
We should add Rust to the readme.
Yes it works when I eval the expression in emacs buffer but that's exacttly what I have in my configuration:
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.

That's weird. Can you set format-all-debug
to t
, then run format-all-buffer
in a Rust buffer and look in the *Messages*
buffer to find the shell command that format-all tried to run?
Hi,
I retried with this configuration with the rust-mode hook deactivated and it seems to work now with this configuration. Sorry for that, but I must have made mistake when I was trying several things with the .emacs...
Ah no... that's because I was trying on souce with no async construction.
That's the message I got:
You can run the command ‘eval-expression’ with M-:
t
Format-All: Formatting lib.rs as Rust using rustfmt
Format-All: Running: /etc/profiles/per-user/mik/bin/rustfmt
Format-All: Directory: /home/mik/Dev/Rust/osc_dispatcher/src/
Type q in help window to delete it.
Formatting error
Mark set
And the error from rustfmt:
error[E0670]: `async fn` is not permitted in Rust 2015
--> <stdin>:8:5

error: `async move` blocks are only allowed in Rust 2018 or later

And after:
(setq format-all-formatters
'(("Rust" (rustfmt "--edition" "2021"))))
it works:
(("Rust" (rustfmt "--edition" "2021")))
You can run the command ‘eval-expression’ with M-:
(("Rust" (rustfmt "--edition" "2021")))

I have tried several things and it seems impossible to pass arguments to rustmt.
especially the edition. Is it possible to specify --edition 2021. But if I set Rust formatter like that:
or like that:
Or if I try with cargo:
It's still 2015 edition that is used.
As rust-mode provide its own format command I can workaround this qith a hook:
But format-all definitively doesn't work for Rust.
