Hi, all I have some C++ source codes. I want make sure there is just a space on both sides of "=". That means script1 will be changed to script2, as following. Script1: int a= 2; a =a+3; Script2: int a = 2; a = a+3; ------------------- I think maybe an elisp function can do this job. I am wondering how to find this elisp code, cause I don't want to reinvent the wheel. Thanks for your attention. -- Thanks & Regards Denny Zhang
