When working in WebStorm, I can see who changed the code in the open file by opening revisions panel.
As I understand, this information is kept inside git and can be fetched.
So, I wonder, if it's possible to find the oldest change made by some ?
Are there tool to perform operations like history searching/filtering by ?
git log --author=user --reverse will give you the list of commits by this user sorted from earliest to newest. See git-log(1) for more details.
