Fix scrolling after gocui update

[mark2185]

This fixes the scrolling caused by a regression in #447 .

It still has some issues regarding highlighting rows, but I'm not overtly interested in diving into gocui given that it's not actively maintained. At least it enables the user to scroll again.

Built using go1.21.0 and tested on Ubuntu 20.04. Unfortunately the scrolling bug is still there. :(

[mark2185]

Ah, I see I've only fixed it for the Image Details pane, thanks.

[mark2185]

I took the liberty of rebasing onto #478 , give it another spin @vinkmr .

[vinkmr]

Yup. Scroll seems to work for me now.

Would be great to see a new release with this fix, as it severely limits the usability of dive for nix-based images :)

Seems like these lines need to be fixed in order to pass ci check

runtime/ui/view/layer.go:298:14: Error return value of `v.vm.Update` is not checked (errcheck)
                v.vm.Update(v.constrainedRealEstate)

Please release this - super annoying bug.

I just had to rebase this PR on top of the current head ( 925cdd86482edec42185794620a1e616b79bbee5 ) of main branch to work around something similar to this:

• https://github.com/wagoodman/dive/issues/452

Thanks for the patch!

[MauriceArikoglu]

Any update? @wagoodman @mehmetumit @mark2185 can you fix the mentioned ci issues?

[LaTrissTitude]

Would be great for this fix to reach the next release

[black-snow]

Sadly, the logs have expired already.

You can still see what was the issue here. https://github.com/wagoodman/dive/actions/runs/6391362920?pr=473

I made another pull request based on this one here, #520, that should hopefully pass all the checks. I just need someone to review and approve it now.

Will be nice if we can finally have this fix in new versions.

This is arguably one of the main features of this tool - and this bug's been open since over a year apparently, with devs asking for its release and offering their time and help. What's the hold up then?

PS: On a related point, the "Layer Details" panel takes up 1/3 of the vertical screen area when in fact it seems to require at most 9 lines (which means, less space the "Layers" panel, making this issue even worse).

[mark2185]

What's the hold up then?

Can't speak for wagoodman since I'm not him, but just a reminder that this is a free, non-paid project, that nobody is forced to develop and/or maintain, there are no deadlines or milestones it has to reach, so we can't really blame anyone.

If you wish to improve upon it, feel free to fork it. But do remember that we're all human, and life sometimes gets in the way.

@mark2185 thanks so much for this patch - The branch might be worth a rebase so the fix still "just works" as is.

I had to rebase your fix on top of the latest version (OCI images on mac weren't loading) but otherwise it worked great.
