vim配置——c++代码自动补全

O 简介

自己配置vim主要分为两大部分：一个是通过set设置vim的属性；另一个是插件下载

一、插件管理器及clangd代码补全

vim插件管理器与其他软件包管理器如yum, apt, 以及python中的pip等相同，都为软件包管理器，vim的软件包管理器又称插件管理器，常见的vim插件管理器有:

vim-plug junegunn/vim-plug: Minimalist Vim Plugin Manager (github.com)
VundleVim : VundleVim/Vundle.vim: Vundle, the plug-in manager for Vim (github.com)

本文安装的是vim-plug，操作系统是WSL Ubuntu20.04

1. vim-plug安装

GitHub的项目给出了两种方法，一种是在命令行直接下载，另一种是在vim的配置文件.vimrc中下载

在命令行直接下载的方法：

curl -fLo ~/.vim/autoload/plug.vim --create-dirs \https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

需要注意的是：raw.githubusercontent.com 可能会访问不到，参考连接：彻底解决【“curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused”】错误_donaldsy的技术博客_51CTO博客

需要修改一下网络的配置文件,修改方法为在/etc/hosts文件里添加raw.githubusercontent.com的ip地址

网站ip地址的查询网站：The Best IP Address, Email and Networking Tools - IPAddress.com

2. 通过vim-plug下载vim插件

在.vimrc中增加要下载的插件名或插件地址，默认地址为github,

以call plug#begin()开头

中间为要下载的插件

最后以call plug#end()结尾

call plug#begin()
" The default plugin directory will be as follows:
"   - Vim (Linux/macOS): '~/.vim/plugged'
"   - Vim (Windows): '~/vimfiles/plugged'
"   - Neovim (Linux/macOS/Windows): stdpath('data') . '/plugged'
" You can specify a custom plugin directory by passing it as the argument
"   - e.g. `call plug#begin('~/.vim/plugged')`
"   - Avoid using standard Vim directory names like 'plugin'" Make sure you use single quotes" Shorthand notation; fetches https://github.com/junegunn/vim-easy-align
Plug 'junegunn/vim-easy-align'" Any valid git URL is allowed
Plug 'https://github.com/junegunn/vim-github-dashboard.git'" Multiple Plug commands can be written in a single line using | separators
Plug 'SirVer/ultisnips' | Plug 'honza/vim-snippets'" On-demand loading
Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }
Plug 'tpope/vim-fireplace', { 'for': 'clojure' }" Using a non-default branch
Plug 'rdnetto/YCM-Generator', { 'branch': 'stable' }" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug 'fatih/vim-go', { 'tag': '*' }" Plugin options
Plug 'nsf/gocode', { 'tag': 'v.20150303', 'rtp': 'vim' }" Plugin outside ~/.vim/plugged with post-update hook
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }" Unmanaged plugin (manually installed and updated)
Plug '~/my-prototype-plugin'" Initialize plugin system
" - Automatically executes `filetype plugin indent on` and `syntax enable`.
call plug#end()
" You can revert the settings after the call like so:
"   filetype indent off   " Disable file-type-specific indentation
"   syntax off            " Disable syntax highlighting

代码自动填充的插件为：

github地址：neoclide/coc.nvim: Nodejs extension host for vim & neovim, load extensions like VSCode and host language servers. (github.com)

" Use release branch (recommend)
Plug 'neoclide/coc.nvim', {'branch': 'release'}" Or build from source code by using yarn: https://yarnpkg.com
Plug 'neoclide/coc.nvim', {'branch': 'master', 'do': 'yarn install --frozen-lockfile'}

.vimrc书写完成后，在vim中执行PlugInstall

然后再利用coc安装coc的扩展

:CocInstall clangd   //表示为c++的代码自动补全

3. vim升级至8.2

(5条消息) linux ubuntu如何装vim,Ubuntu 18.04/20.04下安装Vim 8.2_孔李聃丘的博客-CSDN博客

sudo add-apt-repository ppa:jonathonf/vimsudo apt-get updatesudo apt install vim

4. 升级Nodejs

(5条消息) 升级Ubuntu nodejs 版本_放大的EZ的博客-CSDN博客

安装npm

安装n

升级nodejs

sudo apt-get install  npm
sudo npm install n -g
sudo n stable

5. 安装自动补全扩展

在vim的命令行

CosInsatll coc-clangd

回到命令行安装: 为什么？？？我不理解，但是不安装的话每个vim文件里都要CosInsatll coc-clangd才能提醒

vim-plug+coc.nvim实现vim C/C++自动补全 - 知乎 (zhihu.com)

sudo apt-get install clangd

知道了，没有设置路径

export PATH=$PATH:/home.config/coc/extensions/node_modules/coc-clangd

不知道sudo apt-get install clangd是不是必须要安装的，和CocInstall coc-clangd区别？？

答：sudo apt install clangd安装后的clangd在/usr/bin里面有可执行文件
而在vim中使用:CocInstall coc-clangd安装后可执行文件在/usr/lib/llvm-10/bin/clangd
使用软连接解决该问题

sudo ln -s /usr/lib/llvm-10/bin/clangd /usr/bin/clangd

6. 配置.vimrc

上面的步骤执行完成后，出现了代码提示的功能，但是无论回车或者空格都没有自动补全的效果

将coc项目中的.vimrc配置复制，实现了补全功能

" Some servers have issues with backup files, see #649.
set nobackup

" Requires 'textDocument/selectionRange' support of language server.
nmap <silent> <C-s> <Plug>(coc-range-select)
