Any way to sort diagnostics by severity or to stagger them?

[EriKWDev]

When my rust project (large workspace) doesn't compile I don't really care about HINT:s

And now ERROR:s get put way down on pages afterwards

It would be nice if they could be sorted by severity

Another idea is an option/view which only shows HINT:s if there are no WARN:s and no WARN:s if there are ERROR:s

Is it possible to configure helix/rustlsp to do this?

They seem to be sorted internally per project/file but I really only care about the global scope

[EriKWDev]

I tried sorting the vec flat_diag in helix-term/src/command/lsp.rs by diag.diag.severity in my fork and it gives me the desired behaviour.

Would a PR making this an option be of interest?

You can filter your search by writing %<prefix of column name> <actual regex> so in your case it's: <your regex> %sev !hin.
See https://docs.helix-editor.com/pickers.html#filtering-picker-results for more information.

Is there a way to set the default filter/sort?

If I recall correctly:

[EriKWDev]

Well, then perhaps the more useful PR would be a way to configure default filters/orderings for picker views

[TornaxO7]

Maybe you can ask on the matrix server for more opinions.

You can also apply the filter by default using this little hack in config:

[keys.normal]
space.d = "@<space>D%s error"

this maps small space-d to space-D and error severity filter via macro key binding, since I am usually looking at workspace diagnostics anyway.
You can of course remap further to have both space-d and space-D behave as usual but with filter.

Thanks for the idea bruwozniak, this was really annoying me as there was a lot of clutter from inactive-code hints. I tweaked slightly to just hide hints by default:

[keys.normal]
space.d = "@<space>D%s !H"

Further to @bruwozniak 's solution to remap the diagnostic picker keybinds, I've come up with a solution that works for both workspace and diagnostic pickers, thanks to #12420 (comment).

[keys.normal]
A-S-d = "diagnostics_picker"
A-S-w = "workspace_diagnostics_picker"
space.d = "@<A-S-d>%s !H"
space.D = "@<A-S-w>%s !H"

When / if #12420 lands then this could potentially be simplified to:

[keys.normal]
space.d = ["diagnostics_picker", "@%s !H"]
space.D = ["workspace_diagnostics_picker", "@%s !H"]
