--- Lua language server.
---
--- `lua-language-server` can be installed by following the instructions [here](https://luals.github.io/#neovim-install).
---
--- The default `cmd` assumes that the `lua-language-server` binary can be found in `$PATH`.
---
--- If you primarily use `lua-language-server` for Neovim, and want to provide completions,
--- analysis, and location handling for plugins on runtime path, you can use the following
--- settings.
---
vim.lsp.config('lua_ls', {
	on_init = function(client)
		if client.workspace_folders then
			local path = client.workspace_folders[1].name
			if
				path ~= vim.fn.stdpath('config')
				and (vim.uv.fs_stat(path .. '/.luarc.json') or vim.uv.fs_stat(path .. '/.luarc.jsonc'))
			then
				return
			end
		end

		client.config.settings.Lua = vim.tbl_deep_extend('force', client.config.settings.Lua, {
			runtime = {
				-- Tell the language server which version of Lua you're using (most
				-- likely LuaJIT in the case of Neovim)
				version = 'LuaJIT',
				-- Tell the language server how to find Lua modules same way as Neovim
				-- (see `:h lua-module-load`)
				path = {
					'lua/?.lua',
					'lua/?/init.lua',
				},
			},
			-- Make the server aware of Neovim runtime files
			workspace = {
				checkThirdParty = false,
				library = {
					vim.env.VIMRUNTIME,
					-- vim.fn.expand("~/.local/share/love2d/library"),
					-- Depending on the usage, you might want to add additional paths
					-- here.
					-- '${3rd}/love2d/library'
					-- '${3rd}/busted/library'
				}
				-- Or pull in all of 'runtimepath'.
				-- NOTE: this is a lot slower and will cause issues when working on
				-- your own configuration.
				-- See https://github.com/neovim/nvim-lspconfig/issues/3189
				-- library = {
				--   vim.api.nvim_get_runtime_file('', true),
				-- }
			}

	end,
