I was just issued a new company laptop and have lost all of my VS extensions. I had one that did line by line git blame, so that I could see who had added a line of code six months ago and go ask him why.

I can't find it again in the marketplace. Any ideas?

Git Blame Explained With Examples: Who Touched the Code?
October 21, 2021 - You start by indicating a point in history that contains the “thing” you’re trying to identify the origin of—that’s typically a bug—and another point where you’re sure the code doesn’t contain said element. Git bisect then moves you through the history, allowing you to evaluate each stop as “good” or “bad” until the bisect command identifies the commit which introduced the defect. When should you use bisect over blame?

r/vscode on Reddit: Simply Blame - Idea like git blame annotations to VS Code finally
July 10, 2024 -

Are you the kind of a guy who would like to have git blame annotations inside the text editor sound and clear? And think that the git lens gives too messy presentation nevertheless it has huge amount of features and tools that are too complicated to use. If you like to use the git on the terminal but would like to have a better way of checking the blame annotations than via the terminal. No worries. After a long time of delay I finally got this extension written. The extension does simply one thing, git blame, hence the name simply blame and it presents the blame annotations clearly on the each line of the code. Go check the extension out now. You can install the extension from the VS Code extensions marketplace by searching Simply Blame. Repository: https://github.com/JamiLu/simply-blame
