List errors for the whole project (default/diagnostics)

[rakanalh]

I confirm that...

• I have searched the issue tracker, documentation, FAQ, Discourse, and Google, in case this issue has already been reported/resolved.
• I have read "How to Debug Issues", and will use it to provide as much information about this issue as possible.
• The issue can be reproduced on the latest available commit of Doom.
• The issue can be reproduced on a stable release of Emacs, such as 27, 28, or 29. (Unstable versions end in .50, .60, or .9x)

Expected behavior

Hello,

Why is listing errors for the whole project only implemented for Vertico but not the others?
https://github.com/doomemacs/doomemacs/blob/df5f6696ecf1ffad46a08942d22b1120b6d47ac3/modules/config/default/autoload/default.el#L53-L73

I would expect this would be implemented with 2 keybindings:

• SPC c x list errors for buffer
• SPC c X list errors for project

No matter what completion system you use.

Current behavior

Only way to list errors for the whole project is apparently using Vertico.

Steps to reproduce

• Open any project with LSP (such as Rust) with errors in the project
• SPC c x would list errors in the current buffer

No way to list project-wide errors if you're using ivy

It's only implemented for vertico because the contributors who PRed them are vertico users and are only aware of the commands that consult provides for this functionality. They (and I) aren't aware of any for ivy or helm. I'm not open to PRs for ivy, since I intend to eventually phase the module out at some point (not anytime soon though), but I'll accept a PR for helm, so long as it doesn't introduce too many extra dependencies.

SPC c x list errors for buffer
SPC c X list errors for project

I'd agree to this if there were reliable (and wide-reaching) backends to call upon for these two commands, without too much crossover with other modules. For example, treemacs provides lsp-treemacs-errors-list, but it requires (and only supports) lsp-mode, and not eglot.

EDIT: Nevermind about ivy. I'll accept a PR for ivy, since it'll be some time until I phase it out
