[Misc] python 开发vim 插件初步测试

今日雨夹雪, 晚上闲来没事突然想了解下用python试试VIM插件开发. 于是写了个初步测试.
总体来说相当简单, 几个相当设置语法后, import vim 后就进入python世界了. (相当操作命令vim内:help py了解更多)

1. 测试代码, 放到.vim/plugin目录下, *.vim
2. vim内: Helloworld 和 : Helloname abeen 调用测试方法.

测试如下:

1 " vim plugin test                                                                                                                                                            
   2 " Author: ABeen                                                                  
   3
