I want to calculate a certain developer's contribution based on
different standards of code line count and the importance of the code.

I agree with brian that "number of lines added/removed" is not a perfect
measure of productivity ;-).

But I think that there is a slightly cleaner way to compute the result
you're after, like so:

    git rev-list --author="$who" origin/main |
    git diff-tree --stdin -r --numstat --no-commit-id |
    awk '{ s += $1 + $2 } END { print s }'

Thanks,
