linux项目1----Reage注释工具
傅玮
今天完成自己在linux中的一个项目列子，以前所学的全是照着书上的列子比划练习，没有用到自己实际应用中，虽然这一个项目实用价值不大，但是自己还是很有成就感的，不管怎么样走出了在linux程序开发的第一步了。
linux注释工具，主要是实现对文件添加头注释和函数注释，文件注释和函数注释都支持自定义的，默认对头文件的注释为
//====================================================================== // // Copyright (C) 2007-2012 三月软件工作室 // All rights reserved // // filename :main // description :file description // All rights reserved // // created by Renji at 2012-4-15 // qq:625246906 // url:http://www.marchsoft.cn/ // //====================================================================== 默认对函数的注释为 // <description> // // </description> // <param name=$param></param> // <returns></returns> 其中$param为自定的一个标识，用来换成传递的参数名字，函数有多少参数，本行输出几次， 在程序的实现中主要使用了I/0操作，主要是文件的读取，定位、合并。使我在文件操作上有了进一步的了解和学习。 技术难点是分析每一句的是否为函数的定义语句，为函数定位语句要加上注释，我将所有的语句都默认为标准的。
效果如下。如有个c语言文件，r.c
#include<stdio.h>
void b(int i)
{}
int main()
{
printf("reage ");return 0;
}
使用工具后会生成，r.c.rg文件 文件内容为

int main()
{
printf("reage ");return 0;
