我的.vimrc，代码完成基于YcmCompleteMe版

相应的安装部分见上篇文章：vim学习笔记

.vimrc配置

1.基于YcmCompleteMe、taglist.vim、The-NERD-tree等配置，F2调出目录树窗口，F3调出变量、函数窗口，有点IDE的样子，呵呵！
2.定义了一些基本的快捷键：C-a 全选，C-c 选中状态下复制，F5 编译及运行，F8 调试，gb 跳到定义处。
3.Syntastic部分必需正确配置C++ include的目录。
4.刚有个哥们问怎样表明就成功了，我定义了F4为:YcmDiags命令，按F4就会执行，如果代码正确而运行不出错就成功了，若代码不正确运行就会出现Quickfix窗口，给出错误提示，这也表明配置已经成功。但这个配置其实没多大用处，因为只要一存盘，就会自动调用该命令，呵呵！

.ycm_extra_conf.py配置

拷贝模板~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py到~/
下，主要有两点改动：
1.flags增加对c++相关目录的配置，我把针对OS X的配置删除了。
2.配置文档的倒数8到10注释掉。
