Racket Setup in Nvim

Although DrRacket is great, I prefer a more lightweight way to enjoy Racket using Neovim.

Step 1: Install [racket-langserver]

raco pkg install racket-langserver

I am using LazyVim:

  {
    "neovim/nvim-lspconfig",
    opts = {
      servers = {
        racket_langserver = {},
      },
    },
  },

After that, we can enjoy nice functionalities powered by Racket LSP, e.g., doc lookup, auto-complete, and go-to-definition.

I found that even if tree-sitter-racket is not installed, the highlight still works well. Why?

To enhance the REPL, I further set up the Conjure in LazyVim.

  {
    "Olical/conjure",
    ft = { "racket", "scheme" },
    lazy = true,
    init = function()
    end,
  },

To evaluate the selected code, press <localleader>E. As for LazyVim, the default localleader is \.
