To count a number of lines in C++ or Java or ASCII files by exluding white spaces and comments

[John Smith]

Hi all,

We have huge files in Java and C++ and I need to count the total
number of lines in each of them by excluding white spaces (from the
beginning of a line) and comments (C++, Java comments etc).

There must be some scripts in perl to do this job.

Can anyone kindly let me know? Or, are there any third-party tools to
do this job?

Thanks,
John

Most of this is a FAQ, at least for the C++ part:

perldoc -q comment

Maybe that'll be good enough for Java too?

Removing blank lines can be done with

next if /^\s*$/;

assuming you are reading and processing your lines in a loop.

Thanks Bob!

I am looking out for a third party tool t odo this job. We have
millions of code in one of our Parent directory. I want a total count
of lines, number of blank lines and number of comments in the entire
folder. I am not tlaking about a single file.

Thanks,
John
