rust-analyzer not working in helix

[~] $ cargo --version

Configured language servers:
  ✓ rust-analyzer: /home/sumit/.cargo/bin/rust-analyzer
Configured debug adapter: lldb-vscode
Binary for debug adapter: 'lldb-vscode' not found in $PATH
Highlight queries: ✓
Textobject queries: ✓
Indent queries: ✓

I also tried doing :config-reload and :lsp-restart after adding the following to languages.toml

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

and

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

[kirawi]

See #9398 so try restarting Helix. Also run hx -v and check :log-open when opening a Rust file.

It looks like rust-analyzer can't detect the workspace. Are you running this on a cargo project or a standalone Rust file?

[shark-choke]

a bunch of standalone files

[the-mikedavis]

rust-analyzer needs additional configuration in a rust-project.json file outside of cargo projects: https://rust-analyzer.github.io/manual.html#non-cargo-based-projects

[the-mikedavis]

What does the log say when running in verbose mode? hx -v --log log.txt and attach log.txt

[shark-choke]

helix 23.10 (f6021dd)

[the-mikedavis]

That's hx -V, hx -v starts Helix with verbose logging

[shark-choke]

no I tried hx -v its opening a scratch buffer with nothing in verbose
and also tried the same with file

[the-mikedavis]

That's what it should be doing: it starts Helix in verbose mode which increases the log level, so you'll get info logs in the log file (:log-open, https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file) which includes the messages to and from the language server.
