之前就买过java，c++的书，可是由于懒惰，一直没看，丢在那里5年了。（以上废话）。
现在linux下还没有好的C++ IDE。网络上的朋友都推荐eclipse和 code：：block。粗略的看了下code::block，建工程，管理工程，功能很多，准备以后学习下。 学习C++，目前还是用Vim比较好，轻量。各种丰富的插件支持。
开发环境：
系统：ubuntu 14.04LTS。
工具：Vim7.4
编译，链接，运行：g++
现在贴上Vim的配置：（这是这篇随笔的主要内容，也是为了个人保存配置。层次低，希望看官不要笑话。）

开发中，代码补全和快速插入代码块，这两个是必用的。谁也不想把时间花费在敲一些垃圾代码上。配置中使用YCM来补全代码，
UltiSnips来快速插入代码块。以后插件会慢慢加入。
人人都说Vim是神器。可我用起来非常艰难。经常装了个插件各种问题，处理插件的问题，耗费大量的时间。我经常在怀疑是否自己选对了编辑器。我喜欢Vim的快捷键来编辑代码。可由于年代久远，各种插件多而不全。我觉得Vim只适合用于学习C++的开发，让它来建立工程什么的。。。。还是不要想了。老老实实用Eclipse和CB了。
插入一段代码，来开始我的C++之路：
开发路上，你我同行。。。
