Setting up nushell with LazyVim

Add this file as a custom plugin:

-- ./lua/plugins/nu-lsp.lua

vim.filetype.add({
    extension = {
        nu = "nu",
        nush = "nu",
        nuon = "nu",
        nushell = "nu",
    },
    pattern = {
        [".*"] = {
            function(path, bufnr)
                local content = vim.filetype.getlines(bufnr, 1)
                if vim.filetype.matchregex(content, [[^#!/usr/bin/env (-S )?nu( --stdin)?]]) then
                    return "nu"
                end
            end,
            priority = -math.huge,
        },
    },
})

return {
  -- Set up nu LSP
  { "neovim/nvim-lspconfig", 
    opts = {
      servers = {
        nu_ls = {
          settings = {
            nu = {}
          }
        }
      },
      setup = {
        nu_ls = function(_, opts)
          local lspconfig = require('lspconfig')
          local configs = require('lspconfig.configs')

          configs.nu_ls = {
              default_config = {
                  cmd = { "nu", "--lsp" },
                  filetypes = { "nu" },
                  root_dir = function(fname)
                      local git_root = lspconfig.util.find_git_ancestor(fname)
                      if git_root then
                          return git_root
                      else
                          return vim.fn.fnamemodify(fname, ":p:h")  -- get the parent directory of the file
                      end
                  end
              },
          }
          local capabilities = vim.lsp.protocol.make_client_capabilities()
          capabilities = require('cmp_nvim_lsp').default_capabilities(capabilities)

          lspconfig.nu_ls.setup({ capabilities = capabilities })
          return true
        end
      }
    }
  },
  {
    "nvim-treesitter/nvim-treesitter",
    opts = {
      ensure_installed = {
        "nu"
      }
    },
    init = function()
      local parser_config = require("nvim-treesitter.parsers").get_parser_configs()

      parser_config.nu = {
        install_info = {
          url = "https://github.com/nushell/tree-sitter-nu",
          files = { "src/parser.c" },
          branch = "main",
        },
        filetype = "nu",
      }
    end
  }
}

Then run this command once (As instructed from here):

let remote = "https://raw.githubusercontent.com/nushell/tree-sitter-nu/main/queries/"
let local = (
    $env.XDG_DATA_HOME?
    | default ($env.HOME | path join ".local" "share")
    | path join "nvim" "lazy" "nvim-treesitter" "queries" "nu"
)

let file = "highlights.scm"

mkdir $local
http get ([$remote $file] | str join "/") | save --force ($local | path join $file)
