Rail's Neovim setup

I use AstroNvim as my neovim distro.

The up to date config can be found in my dotfiles repo.

The config uses AstroNvim abstraction, but it can be translated into regular neovim config by assigning the variables and functions to their neovim counterparts.

Some snippet are described below.

Use `GOPACKAGESDRIVER` to speedup `gopls`.

The following LSP config makes gopls use GOPACKAGESDRIVER to use Bazel (rules_go) to expose package data.

---@type LazySpec
return {
  "AstroNvim/astrolsp",
  ---@type AstroLSPOpts
  opts = {
    -- Configuration table of features provided by AstroLSP
    features = {
      inlay_hints = true, -- enable/disable inlay hints on start
    },
    -- customize language server configuration options passed to `lspconfig`
    ---@diagnostic disable: missing-fields
    config = {
      -- clangd = { capabilities = { offsetEncoding = "utf-8" } },
      gopls = {
        env = {
          -- TODO: make GOPACKAGESDRIVER project-specific
          GOPACKAGESDRIVER = "./build/bazelutil/gopackagesdriver.sh",
        },
        directoryFilters = {
          "-_bazel",
          "-inflight_trace_dump",
        },
      },
    },
  },
}

Use `crlfmt` to format Go files.

I use mason.nvim to manage crlfmt and its config. Since this PR, crlfmt can be managed by mason-tool-installer and used bu conform.nvim.

---@type LazySpec
return {
  {
    "WhoIsSethDaniel/mason-tool-installer.nvim",
    opts = {
      ensure_installed = { "crlfmt" },
    },
  },
  {
    "stevearc/conform.nvim",
    opts = {
      format_on_save = {
        timeout_ms = 500,
        lsp_fallback = true,
      },
      formatters = {
        crlfmt = {
          command = "crlfmt",
        },
      },
      formatters_by_ft = {
        go = { "crlfmt" },
      },
    },
  },
}
