类似VS中添加类 A的方法 int abc();

会在对应的实现文件.cpp中自动生成,

int A::abc() {

}

初学python，尝试写了一个脚本，自动根据写好的.h文件完成这一工作，也支持模板类，不过没考虑太多模板可能会有bug。

也可能会有很多其他的bug，不过用了下，感觉还可以，有错误再改正：）

用法

比如有一个abc.h，对应的实现文件abc.cc

1.新建一个abc.cc文件

touch abc.cc

2.运行脚本

./prodef.py  abc.h abc.cc

因为我默认是.cc文件，也可

./prodef.py  abc.h

用google 开源的代码做了一个实验，

我们要处理的gtest-test-part.h如下
