vim 键映射<F7><F8><F9>

写单个程序,如果每次都自己输入:set makeprg=gcc\ .......什么的就太麻烦了.所性自己定义快捷键.当然,大程序就用makefile了.这里只是为了方便下:

---------------------------------------------------------------------------------------------------------------------
,<F7>编译 ,<F8>运行 ,<F9>带参运行
举例:写文件foo_001.c 则make成可执行文件001 .如果有参,文件应是:foo_001.in 则输出foo_001.out
分隔符是下划线,稍微看下就可以随自己个性修改使用
