vim-config

​ 本人前端开发者，学习使用 Vim 进行前端开发，由于Vim本身并没有一些很好的能力，比如代码提示、保存格式化代码等等；因此需要进行各种配置，比如配置.vimrc、安装插件等等，为了后续更换电脑可以快速进行Vim配置，在此写下具体操作，方便后续查看。

插件安装

​ 想要让自己的Vim功能更加强大，那么必须安装各种插件进行配置。进而我们需要一个插件管理工具进行管理，这里我使用的是 vim-plug， vim-plug GitHub.

​ 安装 vim-plug 很方便，查看 github README 即可，本人使用的 MacBook Pro ，具体安装命令：

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

​ 使用方法： .vimrc 配置如下

" Specify a directory for plugins
" - For Neovim: stdpath('data') . '/plugged'
" - Avoid using standard Vim directory names like 'plugin'
call plug#begin('~/.vim/plugged')

" Make sure you use single quotes

" 这里填写自己要安装的插件
" 比如：目录树
Plug 'scrooloose/nerdtree'

" Initialize plugin system
call plug#end()

​ 这样，我们就可以安装自己想要安装的插件了。

coc-nvim

Make your Vim/Neovim as smart as VSCode.

为了实现一系列的功能，本人使用的是 coc-nvim 这款插件, con-nvim GitHub.

为什么使用它？去 github 看看呀！

使用 coc-nvim 需要有node环境 node.js >= 12.12

然后在 .vimrc 中配置

" 本人使用的是第一种方法
" 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'}

con-nvim 可以管理安装自己的插件

// 这是 Vim 命令哦
:CocInstall coc-json coc-tsserve

本人安装的插件

• coc-syntax
• coc-snippets
• coc-prettier
• coc-html-css-support
• coc-html
• coc-highlight
• coc-eslint
• coc-cssmodules
• coc-vimlsp
• coc-vetur
• coc-tsserver
• coc-rome
• coc-json
• coc-css

这个文件的配置，是学习b站up主TheCW的配置.

可在 vim 环境下通过:CocConfig进行查看配置并保存.
