30.0.50; Add Rust compilation regex |
|
Date: |

Hi:
Recently working with rust I have noticed that emacs does not recognizes
the rust/cargo error patterns.
Considering that emacs has now the rust-ts-mode, it may worth adding
the rust/cargo error patterns to compile when using that mode
In my system so far I have this:
```
(with-eval-after-load 'rust-ts-mode
(with-eval-after-load 'compile
(add-to-list
'compilation-error-regexp-alist-alist
`(cargo
"\\(?:\\(?4:error\\)\\|\\(?5:warning\\)\\):[^\0]+?-->
\\(?1:[^:]+\\):\\(?2:[[:digit:]]+\\):\\(?3:[[:digit:]]+\\)"
1 2 3 (5)
nil
(5 compilation-warning-face)
(4 compilation-error-face)))
(add-to-list 'compilation-error-regexp-alist 'cargo)))
```
Maybe a more frequent rust user has a more general regex to
recommend. But this one works for me.
WDYT?

Thanks, installed on master, and closing the bug.
