Fedora上的Vim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、配置 .vimrc

call plug#begin(‘~/.vim/plugged‘)

4:、安装插件
在vim normal模式下输入：PlugInstall，等待安装完成

5、自动补全插件YouCompleteMe配置
安装clang：
sudo dnf install clang
进入目录：
cd ~/.vim/bundle/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/bundle/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)
