（四）plugins.vim
call plug#begin("~/.config/nvim/plugged")
" 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'
" 這裡只新增了 coc 一個外掛
Plug 'neoclide/coc.nvim', {'branch': 'release'}
" Initialize plugin system
" - Automatically executes `filetype plugin indent on` and `syntax enable`.
call plug#end()
