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.

local lsp = {
  settings = {
    gopls = {
      env = {
        -- TODO: make GOPACKAGESDRIVER project-specific
        GOPACKAGESDRIVER = "./build/bazelutil/gopackagesdriver.sh",
      },
      directoryFilters = {
        "-_bazel",
        "-inflight_trace_dump",
      },
    },
  },
}

Use `crlfmt` to format Go files.

Make sure to install crlfmt to make the following section work. This plugin creates :Format and :FormatSave commands, which use crlfmt to format the Go buffers. Note that gopls also runs gofumpt.

-- Lazy plugin snippet
  {
    "mhartington/formatter.nvim",
    cmd = { "FormatWrite", "Format" },
    opts = {
      filetype = {
        go = {
          -- Defines `crlfmt` as a formatter for Go files.
          -- It will be run as a part of :Format or FormatSave
          function()
            return {
              exe = "crlfmt",
              stdin = true,
            }
          end,
        },
      },
    },
  }

This function creates an auto command to run when files are saved. The function is called from polish() (AstroNvim’s function called on load).

-- Run crlfmt on save
local crlfmt_save = function()
  vim.api.nvim_create_augroup("__formatter__", { clear = true })
  vim.api.nvim_create_autocmd("BufWritePost", {
    pattern = "*.go",
    group = "__formatter__",
    command = ":FormatWrite",
  })
end
