Ruby LSP not indexing symbols

[brettpthomas (Brett Thomas)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Ruby LSP extension isn’t indexing symbols properly. I can’t command-click or @-include ruby symbols in Cursor Chat.

• This extension works fine in VSCode
• Ruby LSP is running (screenshot)
• I tried all the ChatGPT suggested remedies (reload, reinstall, etc.) - no luck

Steps to Reproduce

Load a ruby codebase in Cursor, install Ruby LSP extension

Thanks for reporting this!

Could you check and share the Ruby LSP output logs? Go to View > Output, select “Ruby LSP” from the dropdown, and share what you see there.

Also, can you share more about your Ruby setup?

Hi @brettpthomas, which ruby extension are you using? Could you try using this Ruby LSP extension?
