个人的vim简单配置

1.vim配置

已经放弃该方法，coc.nvim NB!

1.1 插件YouCompleteMe安装

首先解决依赖环境，并且编辑好.vimrc，然后进入插件目录，使用git下载ycm

git clone --recursive https://github.com/Valloric/YouCompleteMe.git

该命令可以补全依赖项
由于google无法访问有一个包要自行安装

cd .vim/bundle/YouCompleteMe/third_party/ycmd/third_party/go/src/golang.org/x/ 
rm -r tools 
git clone https://github.com/golang/tools.git

此时可能还有一些依赖项没有安装，使用命令

git submodule update --init --recursive

然后进入文件夹并编译

cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer

如果编译报错，可能是文件不全，按照提示补全文件重新编译。之后查清楚C++头文件的位置，如：

'-isystem',
'/usr/include',
'-isystem',
'/usr/include/c++/7',
'-isystem',
'/usr/include/c++/7.4.0',
'-isystem',
'/usr/include/x86_64-linux-gnu/c++',
'/usr/include/x86_64-linux-gnu/c++/7.4.0',
'-isystem',
'/usr/include/x86_64-linux-gnu/c++/7',

编辑文件，将上面的头文件加到相关位置

vim ~/.vim/bundle/YouCompleteMe/third_party/ycmd/.ycm_extra_conf.py

然后加入.vimrc文件中就行了

let g:ycm_global_ycm_extra_conf='/home/zprhhs/.vim/bundle/YouCompleteMe/third_party/ycmd/.ycm_extra_conf.py
set completeopt=longest,menu    "让Vim的补全菜单行为与一般IDE一致(参考VimTip1228)

2. VIM安装中出现的问题

2.1. YouCompleteMe python3无法补全第三方库

解决方法：

cd ~/.vim/bundle/YouCompleteMe
vim install.py

将代码中的第一行#!/usr/bin/env python修改为#!/usr/bin/env python3，然后在该目录下执行

./install.py --clang-completer

此时便可以链接到python3的第三方库
