local configs = require 'lspconfig/configs'

if not configs.golangcilsp then
 	configs.golangcilsp = {
		default_config = {
			cmd = {'golangci-lint-langserver'},
			root_dir = lspconfig.util.root_pattern('.git', 'go.mod'),
			init_options = {

auto-format = true
language-servers = [ "gopls", "golangci-lint-lsp" ]
