Adding a new LSP server

Follow these steps to add a new LSP server to this Neovim config.

1. Create the server config file

Create lua/lsp/<server_name>.lua that returns a vim.lsp.Config table:

local util = require("util")

--- @class vim.lsp.Config : vim.lsp.ClientConfig
return {
  cmd = { util.homebrew_binary("<formula>", "<binary>") },  -- or util.prefix(), util.go_path(), etc.
  filetypes = { "<filetype>" },
  settings = {
    -- server-specific settings
  },
}

Key conventions:

• Always resolve binary paths via util.homebrew_binary(), util.prefix(), util.bun_prefix(), util.go_path(), or util.pnpm_prefix() — never use bare command names.
• Return a plain table — do NOT call lspconfig.setup().
• Use --- @class vim.lsp.Config : vim.lsp.ClientConfig annotation.
• Add on_attach only if the server needs buffer-specific overrides.

2. Register in lua/lsp/init.lua

If the server exists in lspconfig, add it to the servers table:

["<server_name>"] = require("lsp.<server_name>"),

If the server is NOT in lspconfig, register it first with register_lsp() before the servers table:

register_lsp(
  "<server_name>",
  {
    cmd = { "<binary>" },
    filetypes = { "<filetype>" },
    root_markers = { ".git" },
    single_file_support = true,
    capabilities = default_capabilities_config(),
  }
)

3. Add filetype detection (if needed)

If the filetype isn't already detected by Neovim, add an entry in filetype.lua via vim.filetype.add().

4. Add after/ftplugin (if needed)

For filetype-specific buffer settings, create after/ftplugin/<filetype>.lua.
