Can you provide more context? Do you have the ruby-lsp gem installed? Which Ruby version manager are you using?

[happer64bit]

@vinistock I already install ruby-lsp with gem install ruby-lsp and My Ruby version is Ruby+Devkit 3.1.2-1 (x64) from https://rubyinstaller.org/

[vinistock]

We currently only support shadowenv as a Ruby version manager. The work to add support for more version managers is in #1481 and I have added rubyinstaller to the list.

The LSP should work properly once the issue is completed.

EDIT:

It seems auto-completion isn't supported without Sorbet: #61

And I'm guessing the same is true for documentation pop-ups on hover, etc.

Code formatting and diagnostics (e.g. syntax errors) are working though!

Leaving my original comment in case it helps anyone else that ends up here via their favorite search engine:

@vinistock In the interim, could you provide some guidance on what's required in the shadowenv config? I've cobbled together the following (in .shadowenv.d/ruby.lisp):

(provide "ruby" "2.7.5")

(when-let ((ruby-root (env/get "RUBY_ROOT")))
 (env/remove-from-pathlist "PATH" (path-concat ruby-root "bin"))
 (when-let ((gem-root (env/get "GEM_ROOT")))
   (env/remove-from-pathlist "PATH" (path-concat gem-root "bin")))
 (when-let ((gem-home (env/get "GEM_HOME")))
   (env/remove-from-pathlist "PATH" (path-concat gem-home "bin"))))

(env/set "GEM_PATH" ())
(env/set "GEM_HOME" ())
(env/set "RUBYOPT" ())

(env/set "RUBY_ROOT" (path-concat (env/get "HOME") ".rvm/rubies/ruby-2.7.5"))
(env/prepend-to-pathlist "PATH" (path-concat (env/get "RUBY_ROOT") "bin"))
(env/set "RUBY_ENGINE" "ruby")
(env/set "RUBY_VERSION" "2.7.5")
(env/set "GEM_ROOT" (path-concat (env/get "HOME") ".rvm/rubies/ruby-2.7.5/lib/ruby/gems/2.7.0"))

(when-let ((gem-root (env/get "GEM_ROOT")))
  (env/prepend-to-pathlist "GEM_PATH" gem-root)
  (env/prepend-to-pathlist "PATH" (path-concat gem-root "bin")))

(let ((gem-home  
      (path-concat (env/get "HOME") ".rvm/gems/ruby-2.7.5@recommendation-service")))
  (do
    (env/set "GEM_HOME" gem-home)
    (env/prepend-to-pathlist "GEM_PATH" gem-home)
    (env/prepend-to-pathlist "PATH" (path-concat gem-home "bin"))))

And the ruby-lsp extension no longer reports any problems, but I still don't get any autocompletion/docs-on-hover/etc.

The only messages I see in VSCode's "Ruby LSP" OUTPUT tab is:

@cstrahan-blueshift indeed the features you mentioned aren't supported without Sorbet. Implementing them accurately requires type checking, which the Ruby LSP does not do.

Based on the output in VS Code, the Ruby LSP seems to be working properly.

We have ideas on how to implement a more naive approach to things like go to definition, hover, signature help and autocompletion, based on simple indexing and name matching, but we haven't gotten to explore them yet. The issues are in our roadmap.
