Highlight Code Lines Modified/Created in the Last Commit

[Almusamim]

I'm wondering if there's currently a way to visually highlight the lines modified in the most recent (last) commit within the editor. Similar to how VS Code highlights modified or added lines since the last working tree change (green, yellow, red), but scoped strictly to the most recent or specific Git commit.

Is this feature already available in GitLens (perhaps a feature I’ve missed)?

🔍 Use Case

• I'd like to easily identify what was changed in the last commit directly in the editor, without needing to open a separate diff or use the blame/line history.
• This would be especially helpful during code reviews or when returning to a branch after a break and wanting to quickly reorient myself to the most recent changes.

Yes, the "File Changes" annotation can behave like that, depending on the current file "state". If you have staged or unstaged changes, then it will highlight those changed lines, but if not, it will highlight the lines changed in the most recent commit.

You can toggle the on/off via the Toggle File Changes command in the Command Palette or the editor toolbar:

You can configure the annotations by jumping to "File Changes" in the GitLens Settings Editor (GitLens: Open Settings from the Command Palette).

You can also (on that same Settings UI), configure the Git CodeLens to work in concert with the File Changes annotation, by choosing to toggle the annotation when clicking on the Git CodeLens. In this mode, the File Changes will highlight the lines changed from the commit that most recently changed that "block" of code

Hope that helps

Thank you for sharing these commands, they’re very useful! 😊

I tried using the "Toggle File Changes" command, but it doesn’t quite do what I’m looking for.

What I’d like is a way to see the changes from the last commit highlighted with a gutter indicator, with a color like blue. At the same time, I’d still like to see uncommitted changes highlighted normally, as is usually done.

With "Toggle File Changes", I only see the changes from the last commit, and as soon as I start editing the file, it switches to highlighting just my recent changes.

I noticed there's a File Heatmap option that can highlight changes within number of days, not exactly what I need but very close.

Thanks again for the help, I really appreciate it!
