1. 安装插件系统

使用的是vim-plug

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

2. 安装插件

打开~/.vimrc, 在其中写入：

" 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

" Shorthand notation; fetches https://github.com/junegunn/vim-easy-align Plug 'junegunn/vim-easy-align'
" Any valid git URL is allowed
Plug 'junegunn/vim-github-dashboard'


" 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'

" auto complete
Plug 'Valloric/YouCompleteMe'

" auto complete ()[]{}
Plug 'tmsvg/pear-tree'

Plug 'preservim/nerdtree'

Plug 'vim-airline/vim-airline'

Plug 'vim-airline/vim-airline-themes'

Plug 'preservim/tagbar'

Plug 'rust-lang/rust.vim'

Plug 'maxmx03/dracula.nvim', { 'branch': 'vim' }

Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

Plug 'junegunn/fzf.vim'


Plug 'NLKNguyen/papercolor-theme'

" Initialize plugin system
call plug#end()

" 设置行号
set nu

" 设置tab
set ts=4
%retab!

" 设置YouCompleteMe不需要预览
set completeopt-=preview

if !isdirectory(&undodir)
                call mkdir(&undodir, 'p', 0700)
endif

set nobackup
set undodir=~/.vim/undodir

" 设置ctrl+n打开目录
map <C-n> :NERDTreeToggle<CR>

" 设置F8打开tag bar
nmap <F8> :TagbarToggle<CR>

" 设置搜索高亮
"set nohlsearch

" 停止搜索高亮的键映
nnoremap <silent> <BS> <BS>:nohlsearch<CR>

set backspace=2


"设置pear_tree自动补全的括号可见
let g:pear_tree_repeatable_expand=0

" 设置主题
set background=dark
colorscheme PaperColor

let g:go_imports_autosave = 1
let g:go_fmt_autosave = 1
let g:go_imports_mode = 'gopls'
let g:go_fmt_command = 'gopls'

let g:ycm_key_list_select_completion = ['<Enter>', '<C-n>']

set shiftwidth=4
set expandtab
set tabstop=4

map <C-\> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
map <A-]> :vsp <CR>:exec("tag ".expand("<cword>"))<CR>


" Alt-right/left to navigate forward/backward in the tags stack
map <C-Left> <C-T>
map <C-Right> <C-]>

然后在命令模式下执行：PlugInstall

等待一段时间，一些插件将会被安装到vim上

3. 使用主题

这里选择molokai主题

下载主题文件

git clone https://github.com/tomasr/molokai.git

cd molokai && mv colors/molokai.vim ~/.vim/colors/

使用主题

在~/.vimrc文件中写入：

:colorscheme molokai

重新进入vim，主题已经生效

4. 自动补全

这里使用的是YouCompleteMe 在vim plug中添加插件

Plug 'Valloric/YouCompleteMe'

vim运行:PlugInstall

添加完成后还需要手动编译

cd ~/.vim/plugged/YouCompleteMe && python3 install.py --all --verbose

--all代表要安装所有语言的自动补全功能，如果你只需要某个语言的(如C语言)，可以使用--clang参数代替--all

使用YouCompleteMe时会跳出函数文档，可以设置不显示：

set completeopt-=preview

5. 其他配置

  1. 括号自动补全
Plug 'tmsvg/pear-tree'
  1. 显示行号
set nu
  1. tab替换为4个空格
set ts=4
%retab!
