How to add clippy diagnostics for Rust projects in 22.10?

[mahor1221]

Prior to 22.10, I used this configuration to enable clippy diagnostics in Rust projects:

[[language]]
name = "rust"
[language.config.check]
command = "clippy"

I've tried using the new format explained in the documentations, but it doesn't work:

[[language]]
name = "rust"
language-servers = [ { name = "clippy", only-features = [ "diagnostics" ] } ]

Am I doing it wrong?

Try this:

[[language]]
name = "rust"
language-servers = ["rust-analyzer"]

[language-server.rust-analyzer.config]
check.command = "clippy"

Wiki seems to be already updated: https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers#rust

Thank you, I wasn't aware of the wiki. Bookmarked it.

I had a quick Google, I thought it was:

[language-server.rust-analyzer.config]
checkOnSave = { command = "clippy" }

Has something changed?

Yeah I believe that was a change in rust-analyzer. I remember it being checkOnSave a while ago but the docs now recommend tuning check.command: https://rust-analyzer.github.io/manual.html#clippy. It might have been changed because, IIRC, checkOnSave didn't have a way to customize the arguments to pass to the command
