Setting up Helix with Ruby LSP along with Sorbet and RuboCop

[vmrocha]

I mainly use vscode for my Ruby development and, usually, all I need to do is install the extension and it takes care of all the setup for me. I recently started to experiment with Helix and got confused on what is the role of Ruby LSP along with the other gems like Sorbet and RuboCop.

Is setting all of them side-by-side the right way to do it? Or should I let Ruby LSP delegate when it needs Sorbet? Here is how I currently have my setup:

[language-server.sorbet]
command = "bundle"
args = ["exec", "srb", "tc", "--lsp"]

[language-server.rubocop]
command = "bundle"
args = ["exec", "rubocop", "--lsp"]

[language-server.ruby-lsp]
command = "ruby-lsp"
args = ["ruby-lsp"]

[[language]]
name = "ruby"
language-servers = ["sorbet", "rubocop", "ruby-lsp"]
auto-format = true
roots = ["Gemfile", ".bundle"]

The Ruby LSP provides built-in integrations for RuboCop. For Sorbet, we don't have deep integrations yet - we just turn off certain features that we know Sorbet is better positioned to provide.

For the editor setup, having the Ruby LSP and the Sorbet language server is enough (notice that you still need the rubocop gem in your project, so that the LSP can hook to it for formatting and diagnostics).
