Git diff Split view

[Nitemaeric]

Add the ability to view diffs side-by-side, in addition to line-by-line.

For example, the GitHub diff view allows a user to view changes in a "Unified" view or a "Split" view.

I tend to view changes side-by-side by default. Personally, this allows me to visually grep the changes more efficiently - likely because I can view the code as it now is while being able to reference the previous commit. Git blame-ish, in a way.

#4523

Could you elaborate? I did a quick pass on #4523, and I failed to tell how it covers this feature. From my read, that feature request is about the diff source (two Git versions v.s. two arbitrary files), while this feature request is about how we present the diff. They seem to be orthogonal to each other.

The main issue here are related to the side-by-side UX in Zed, including scroll-related adjustments and many other.
Then, whatever to display, git diff or file diff, is not very important as Zed is able to derive diff metadata from both currently.

[FranklinYu]

I agree, but I’m still not seeing how the “side-by-side UX in Zed” is discussed in #4523. That issue doesn’t even mention the term “side-by-side”.

Feel free to add some.

yeah, or at least a way to switch from inline to sidetoside.

why have this been closed? there is still no way to split the diff view in two separate removed/added sides still, right?

[oussama-he]

The same here.

[baltermia]

There's seriously no side-by-side diff in zed? What even is this editor.

And the issue is closed?

This is ridiculous.

I would love to see this feature. Is there anything planned regarding this?

Additionally (but not related to this issue), I am still looking for the feature that allows you to restore a file to prior edits without needing to rely on git, see https://stackoverflow.com/a/72593539
