  • A few words on Ruby's type annotations state
    1 project | /r/ruby | 5 May 2023
    My favorite typing solution so far in ruby is Solargraph
  • Nice Ruby IDEs
    2 projects | /r/ruby | 24 Mar 2023
  • Using SyntaxSuggest with Solargraph LSP!
    3 projects | /r/ruby | 28 Dec 2022
    Yay! For those who don’t know solargraph provides a language server protocol (LSP) for Ruby so that your IDE (like vscode) can know more about the code you’re writing
  • Ruby Delights Built into the Language: No Gems Required
    9 projects | | 20 Dec 2022
    If you're looking for IDE-level language assistance, I can't help you, but since you mentioned nvim: I use regular vim with CoC / Conquer of Completion (vim plugin; LSP server, may not strictly be necessary for nvim), Solargraph (Ruby Gem; language server), and Rubocop (also a Gem) for linting. I previously/still use ALE (vim plugin; Asynchronous Lint Engine) because I haven't gotten CoC+Solargraph to play nice with Rubocop, probably due to something silly.

    My impression with all of this running under MacVim... it's plenty responsive. It can take a while for Solargraph to index everything on startup if you're working in a big project; once it loads, it's snappy. (There's probably a way to cache that startup scan.)

  • I need help with lsp-mode setup
    2 projects | /r/emacs | 17 Nov 2022
    I am trying to use lsp-mode for ruby via solargraph and for Rails era templates using web-mode via lsp-tailwindcss and both seems to kinda sorta work but neither one is really giving me all the features that I see that others have.
  • State of the Ruby language server (LSP) ecosystem / looking for suggestions
    11 projects | /r/ruby | 2 Oct 2022 Seems to be the most mature/developed one. Slow on my system, bad documentation. Language docs are shipped as "cores" you imperatively download that float around in your home directory; this is messy and prone to failure. Doesn't have any docs for versions of ruby past 2.7.
  • Trouble With Solargraph Completions
    1 project | /r/neovim | 29 Sep 2022
    I have recently installed Solargraph and can see that when I open a Ruby file that the LSP is attached to my buffer via `LspInfo`. However whenever I am trying to do some very basic completions or see what kind of methods are available for an object, literally nothing happens. What I am aiming for is something like on the official Solargraph website:
  • Linting and Auto-formatting Ruby Code With RuboCop
    12 projects | | 29 Jun 2022
    If you use Vim or Neovim, you can display RuboCop's diagnostics through coc.nvim. You need to install the Solargraph language server (gem install solargraph), followed by the coc-solargraph extension (:CocInstall coc-solargraph). Afterwards, configure your coc-settings.json file as shown below:
  • anyone here using neovim for ruby on rails projects?
    10 projects | /r/neovim | 14 Jun 2022
    The builtin LSP works well with solargraph to provide autocompletion.
  • Sorbet: Stripe's Type Checker for Ruby
    6 projects | | 29 Mar 2022
    Sorbet and/or RBS seems like they may be the future given how popular typescript is with JS programmers these days. There are some other projects that assist programmers without relying on formal type definitions in the source or shadow typing files:

    Solargraph combines inference and insight from YARD docs (standard for many gems, plus Castwide has written more YARD for the standard library) to make some pretty good guesses. Crucially it has plugins that add the insights from popular gems with static analysis (e.g. reek, rubocop). I maintain solargraph-rails, which parses your Ruby to make guesses about (surprise) Rails.

    The typeprof gem can help IDE plugins make typing guesses based on your tests. This project is interesting to me because it's going into Ruby 3.1 so I think it reflects awareness from the core ruby team that many programmers are not ready to add types to their code.
