12_[nvim0.5+从0单排]_nvim内置lsp搭建lua IDE
12nvim内置lsp搭建lua IDE
大家好，本期内容主要是说如何手动搭建lua的开发环境。
其他开发语言的手动配置教程可以参考下面链接： https://github.com/neovim/nvim-lspconfig/blob/master/CONFIG.md
自动安装自动安装很简单:LspInstall lua一行命令搞定。但是今天主要请的并不是自动安装，而是手动安装。
详情请参考 《09_[nvim0.5+从0单排]_nvim内置lsp搭建python IDE》 https://www.bilibili.com/video/BV1cQ4y1z7J3/
手动安装 下载lua-language-server.zip并解压这个文件我是从github上下载的，没做任何修改。为了方便一些github访问慢的朋友，可以从我的百度云分享中下载。
链接: https://pan.baidu.com/s/1K7PB3J538iL-1nWZNJT6HQ 提取码: yiqn 
下载以后解压到本地任意路径，我这里的解压路径是：
~/.local/share/nvim/lsp/lua-language-server
你可以根据自己的需要来修改，后面的配置文件中会用到这个路径。 
新增配置文件
~/.config/nvim/lua/lspconf/lua.lua
文件内容如下：
local nvim_lsp = require('lspconfig')
-- 在语言服务器附加到当前缓冲区之后
-- 使用 on_attach 函数仅映射以下键
Itkey_on_attach = function(client, bufnr)
local function buf_set_keymap(...) vim.api.nvim_buf_set_keymap(bufnr, ...) end
local function buf_set_option(...) vim.api.nvim_buf_set_option(bufnr, ...) end
--Enable completion triggered by
buf_set_option('omnifunc', 'v:lua.vim.lsp.omnifunc')
-- Mappings.
local opts = { noremap=true, silent=true }
-- See `:help vim.lsp.*` for documentation on any of the below functions
buf_set_keymap('n', 'gD', 'lua vim.lsp.buf.declaration()', opts)
buf_set_keymap('n', 'gd', 'lua vim.lsp.buf.definition()', opts)
--buf_set_keymap('n', 'K', 'lua vim.lsp.buf.hover()', opts)
buf_set_keymap('n', 'gi', 'lua vim.lsp.buf.implementation()', opts)
--buf_set_keymap('i', '', 'lua vim.lsp.buf.signature_help()', opts)
buf_set_keymap('n', 'wa', 'lua vim.lsp.buf.add_workspace_folder()', opts)
buf_set_keymap('n', 'wr', 'lua vim.lsp.buf.remove_workspace_folder()', opts)
buf_set_keymap('n', 'wl', 'lua print(vim.inspect(vim.lsp.buf.list_workspace_folders()))', opts)
buf_set_keymap('n', 'D', 'lua vim.lsp.buf.type_definition()', opts)
--重命名
buf_set_keymap('n', 'rn', 'lua vim.lsp.buf.rename()', opts)
--智能提醒，比如：自动导包 已经用lspsaga里的功能替换了
--buf_set_keymap('n', 'ca', 'lua vim.lsp.buf.code_action()', opts)
buf_set_keymap('n', 'gr', 'lua vim.lsp.buf.references()', opts)
buf_set_keymap('n', 'e', 'lua vim.lsp.diagnostic.show_line_diagnostics()', opts)
--buf_set_keymap('n', '', 'lua vim.lsp.diagnostic.goto_prev()', opts)
buf_set_keymap('n', '', 'lua vim.lsp.diagnostic.goto_next()', opts)
buf_set_keymap('n', 'q', 'lua vim.lsp.diagnostic.set_loclist()', opts)
buf_set_keymap("n", "f", "lua vim.lsp.buf.formatting()", opts)
-- 代码保存自动格式化formatting
if client.resolved_capabilities.document_formatting then
vim.api.nvim_command [[augroup Format]]
vim.api.nvim_command [[autocmd! * ]]

vim.api.nvim_command [[augroup END]]
end
end

~/.config/nvim/after/plugin/nvim-cmp.lua
增加如下一行：
require("lspconf.lua")
因为lua 的lsp没有自带代码格式化的功能，所以我们使用第三方的插件来格式化lua的代码。 packer插件管理器安装方法
修改~/.config/nvim/lua/plugins.lua文件，并在use 'wbthomason/packer.nvim'增加如下内容：
--代码格式化工具，主要用于lua语法格式化
use "mhartington/formatter.nvim"
:wq退出重新打开nvim后，执行:PackerInstall 安装成功。
安装用于lua代码格式化的命令行程序
npm i -g lua-fmt
新增配置文件
~/.config/nvim/after/plugin/formatter.lua
内容如下：
local status, formatter = pcall(require, "formatter")
if (not status) then
return
end
formatter.setup(
{
filetype = {
lua = {
-- luafmt
function()
return {
exe = "luafmt",
args = {"--indent-count", 2, "--stdin"},
stdin = true
}
end
},
sql = {
-- sqlformat
-- 安装方法:pip3 install --upgrade sqlparse
function()
return {
exe = "sqlformat",
-- upper|lower
args = {"-k", "lower", "-i", "lower", "-r", "-"},
stdin = true
}
end
}
}
}
)
--配置保存文件自动格式化代码
vim.api.nvim_exec(
[[
augroup FormatAutogroup
autocmd!
autocmd BufWritePost *.rs,*.lua FormatWrite
augroup END
]],
true
)
