Support only showing diff of lines within the selected range in Line History view

[cideM]

Here's what I would assume most people expect from line history:

• Select a range of lines.
• Activate line history.
• See how those lines changed, and only those lines

I hovered over every icon but I can't figure out how to achieve the same result in line history. Here's what happens in GitLens.

• Select a range of lines
• Click a commit in the line history view
• Get a diff which includes all changes from that commit pertaining to that file. Which is useless, since what's the point of line history if it shows me the same as file history.

Select lines

This is what I get after clicking a commit in line history explorer

Here's the result of wrapping git log -L in like a 5 line vimscript function

@cideM Line history while providing similar behavior to file history, only shows the set of commits that affected the line or lines. As you note, the comparisons are based on the full commit changes to that file rather than just the line range. I chose that because a) I often wanted to see other changes outside just those lines and b) it was easier. I would disagree that this makes the line history "useless".

I am planning to add a new feature (see #335 & #404) that should hopefully also address this issue. But I have no ETA on when that would happen.

Maybe useless was a bit strong but if one would like to see changes outside just those lines then I would assume file history is most appropriate or doing line history with a larger range. It seems like the feature in its current implementation is lacking focus. Thanks for the reply though!
