# Selecting language servers

If there are multiple installed, the highest priority will win. To select the server you want independent of priority you can do this: 

(add-to-list 'lsp-disabled-clients 'ruby-ls) ;; solargraph
(add-to-list 'lsp-enabled-clients 'ruby-lsp-ls) ;; ruby-lsp (shopify's thing)

# Typescript / Javascript

# Setup

Followed these instructions https://emacs-lsp.github.io/lsp-mode/page/lsp-typescript/ for ls-ts Node dependencies needed:

  • typescript-language-server
  • typescript

Weirdly, I got an error that it couldn’t find typescript even though it was installed globably and was in my path. I had to copy the node module into the emacs npm cache: 

cp -R .config/yarn/global/node_modules/typescript spacemacs/.cache/lsp/npm/typescript

# Ruby

There are a bunch of options for LSP servers. You can have multiple servers and the one used can be specified in a dir-local file See also emacs-lsp FAQ

# Ruby LSP

2023-08-04: I tried it but it didn’t appear to have jump to definition or any features for that matter.

# Solargraph

It doesn’t require yard, but it can help it out.

# Setup

Just follow the instructions linked above. For spacemacs, set the ruby-mode backend to 'lsp

  • Rails

    Use the solargraph-rails plugin. When using this you’ll need to include "**/*.rb" and use the exclude directive in the .solargraph.yml

# Features

  • autocompletion
  • other things…

# Vue2

Install vls

# Issues

When trying to start vls: 

Error: Cannot find module 'vscode-css-languageservice/lib/umd/data/browsers'

# Performance

I had performance issues with LSP mode, especially with Typescript.

See https://emacs-lsp.github.io/lsp-mode/page/performance/ for suggestions.

I increased the read-process-output-max to 3mb and that seemed to help.

I was already using emacs v28, so I just rebuild it with native comp. There was some pain making the transition, but it completely solved the performance issues.

See https://xenodium.com/emacs-plus-with-native-comp/ and https://github.com/d12frosted/homebrew-emacs-plus#emacs-27-and-emacs-28-options

# In editor docs

This can sometimes be annoying. Turn it off with lsp-toggle-signature-auto-activate
