Nvim LSP sumneko_lua Running in

问题

sumneko_lua 在编辑的时候 LSP 只进入单文件模式，对于 require 导入的文件、函数不进行补全

配置：

  if server.name == "sumneko_lua" then
    opts = {
      cmd = { "lua-language-server" },
      settings = {
        Lua = {
          runtime = {
            version = 'LuaJIT',
            path = vim.api.nvim_get_option('path')
          },
          diagnostics = {
            globals = { 'vim', 'use' },
          },
          workspace = {
            library = {
              [vim.fn.expand('$VIMRUNTIME/lua')] = true,
              [vim.fn.expand('$VIMRUNTIME/lua/vim/lsp')] = true,
              -- vim.api.nvim_get_runtime_file("", true)
            },
            ignoreDir = { '.git', '.vscode', '.idea', 'site' },
            maxPreload      = 2000,
            preloadFileSize = 2000,
          },
          telemetry = { enable = false, }
        },
      },
      single_file_support = true,
    }
  end

解决

设置 root_dir，升级为项目(针对 runtime_path 内所有 lua 文件)

root_dir = require "lspconfig".util.root_pattern('*.lua'),

-- 或者
root_dir = require "lspconfig".util.root_pattern('init.lua', 'lua'),

  if server.name == "sumneko_lua" then
    opts = {
      cmd = { "lua-language-server" },
      root_dir = require "lspconfig".util.root_pattern('init.lua', 'lua'),  -- 设置 root_dir
      settings = {
        Lua = {
          runtime = {
            version = 'LuaJIT',
            path = vim.api.nvim_get_option('path')
          },
          diagnostics = {
            globals = { 'vim', 'use' },
          },
          workspace = {
            library = {
              [vim.fn.expand('$VIMRUNTIME/lua')] = true,
              [vim.fn.expand('$VIMRUNTIME/lua/vim/lsp')] = true,
              -- vim.api.nvim_get_runtime_file("", true)
            },
            ignoreDir = { '.git', '.vscode', '.idea', 'site' },
            maxPreload      = 2000,
            preloadFileSize = 2000,
          },
          telemetry = { enable = false, }
        },
      },
      single_file_support = true,
    }
  end
