How do you count absolute code changes volume?

[Eugene Lisitsin <li...@glowbyte.com>]

Hi,


I need to count how much work (measured in lines of code) had been
done during certain period of time. If I take just two revision at the
beginning and at the end of this period, and compare them, the
measurement will not reflect all kinds of refactoring, etc.

What I need is to measure the absolute volume of changes for each
commit, then aggregate.

Are there any convenient means of doing this?


Thanks,
Eugene Lisitsin

I think you need to write a script.

(pseudocode)

for rev in [starting_rev, final_rev)   # watch for fencepost error
    svn diff -r rev:rev+1 >> results
egrep -c "^[+-][^+-]" results

Though when your "productivity" metric has roughly a 100% margin of error, 
worrying about the 2% difference between measuring net and gross seems 
rather silly.
