Re: Number of lines of code changed between tags

[Matthew Riechers]

Here's an awk script that shows the lines for each file in a diff, with totals 
at the end.
It looks like what you get from a cvs log. Just change "Index" to "diff" for a 
non-cvs diff.

use like:

cvs diff -r tag1 -r tag2 |awk -f diffloc.awk

It's ugly but it works :)

/^</ {j++}

/^Index/ {
        if (saved) {
                printf ("%s\t+%d -%d lines\n", saved, i, j)
                l_in += i
                l_out += j
                i = j = 0
        }
        saved = $0
}

END {printf ("\t\ttotal: +%d -%d lines\n", l_in, l_out)}
