安装配置vim-plug

安装vim-plug

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

配置vim-plug

在家目录下创建.vimrc配置文件

在.vimrc下填写配置

vim ~/.vimrc

call plug#begin()
Plug 'neoclide/coc.nvim'
Plug 'asins/vimcdoc'
Plug 'preservim/nerdtree'
Plug 'mhinz/vim-startify'
Plug 'luochen1990/rainbow'
 
call plug#end()

安装coc.nvim插件

更新vim

sudo add-apt-repository ppa:jonathonf/vim

sudo apt-get update

sudo apt-get install vim

安装node

sudo apt update
sudo apt install nodejs npm
sudo curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt install nodejs

添加coc.nvim到.vimrc文件

call plug#bing()
 Plug 'neoclide/coc.nvim', {'branch': 'release'}  
call plug#end()

:PlugInstall 安装自动补全插件
:CocInfo 检查插件安装情况
:CocInstall coc-json coc-tsserver支持JSON和Typescript相关子插件

配置服务器

:CocConfig添加Python配置数据
:CocInstall coc-pyright

设置TAB 代码补全

在.vimrc文件中添加以下代码

set nobackup
set nowritebackup
set updatetime=300
set signcolumn=yes
inoremap  
      \ coc#pum#visible() ? coc#pum#next(1):
      \ CheckBackspace() ? "\" :
      \ coc#refresh()
inoremap  coc#pum#visible() ? coc#pum#prev(1) : "\"

inoremap   coc#pum#visible() ? coc#pum#confirm()
                              \: "\u\\=coc#on_enter()\"

function! CheckBackspace() abort
  let col = col('.') - 1
  return !col || getline('.')[col - 1]  =~# '\s'

" Remap  and  for scroll float windows/popups.

endif

" Use CTRL-S for selections ranges.
" Requires 'textDocument/selectionRange' support of language server.
nmap   (coc-range-select)
xmap   (coc-range-select)

" Add `:Format` command to format current buffer.

" Add (Neo)Vim's native statusline support.
