功能

neocomplete 为 vim 提供智能提示功能，将 vim 改造成强大的IDE，效果如下图。

安装

安装neocomplete 插件需要lua支持，并且vim版本大于Vim 7.3.885。

1. 环境检测

　打开vim，输入：version，查看版本与lua模块，若版本不符合，先升级版本；若vim中不支持lua，则需要

重新编译vim，可以参考 recompile vim with lua。

　　注意： +lua 表示支持lua， -lua表示不支持，需要重新编译。

2. 下载neocomplete

　　GitHub：https://github.com/Shougo/neocomplete.vim

　　CSDN：http://download.csdn.net/detail/spch2008/8828389

　　将autoload 文件夹置于 ~/.vim/autoload

　　将plugin 文件夹置于 ~/.vim/plugin

3. 启用neocomplete　　

　　在 ~/.vimrc 中，写入： let g:neocomplete#enable_at_startup = 1

　　至此，neocomplete配置完成。同时，作者提供了一份neocomplete的配置，

如果没有特殊需要，可以直接使用。
