C++根据.h文件批量生成需要的函数框架
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
