Vim配置笔记
1、安装vim
sudo dnf install vim
2、插件管理
选择vim-plug，vim-plug 是韩国人junegunn (Junegunn Choi) 写的， 目前最快插件管理器，无论是更新，安装，全都是并发的 ( https://github.com/junegunn/vim-plug ) 。
在用户目录下下载Vim-plug并把它放在autoload目录里:
curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
执行完以上命令，再在.vim目录下新建一个plugged目录，用来放置插件，最终.vim目录下有autoload和plugged两个目录。
3、.vimrc配置

4:、安装插件
在vim normal模式下输入：PlugInstall，等待安装完成
5、YouCompleteMe配置
安装clang：
sudo dnf install clang
进入目录：
cd ~/.vim/plugged/YouCompleteMe
编译：
./install.sh --clang-completer --system-libclang
--clang-completer表示支持c系列补全。
配置.ycm_extra_conf.py：
先复制到~目录
cp ~/.vim/plugged/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/
再修改
vim ~/.ycm_extra_conf.py
用命令查看库路径：
echo | clang -v -E -x c++ -
结果可能如下：
clang version 3.6.2 (tags/RELEASE_362/final)

太长了，这里省略一部分中间内容；.........表示生咯的内容
这里就是需要包含的路径下面这些都是需要包含的路径

整理上述内容，并添加到flag中
