Question

for a documentation of the code for legal issues, I am required to somehow document which exactly files were changed and WHAT EXACTLY was changed in the source code by a given programmer in git repositary.
Is there any way to make it quite easy and nice?
Maybe there is some tool?

Well, in the simplest case, you’d just display all commit diffs by that developer:

git log -p --author='name of author' --full-history --all

To limit git log‘s output to a time range, specify the --since/--after and --until/--before options:

git log -p --author='name of author' --since=... --until=... --full-history --all
