For those not familiar with meld:

https://gitlab.gnome.org/GNOME/meld/

There is a GitHub repo of it that is now deprecated, this is apparently the official repo. I’m curious how these stack up to other, similar tooling, but for now I’m starting to wonder how much work it would take to modify GNOME Sushi [1] to call one of these utilities when two items are selected in the GNOME Nautilus file manager, and go one step beyond macOS Quick Look (though we would still be missing the Quick Look powerful editing capabilities).

I'm currently working on comparing 2 directories of around 3000 JSON/YAML files each, and while meld can open the diff viewer in a few seconds, diffoscope can't seem to process them.

I love meld, makes my life so much easier :3

EDIT: diffoscope got unstuck after some minutes, but I still prefer the default GUI viewer from meld.

Can’t get meld to work on macos anymore :(

I recommend Meld as well. I have used it for years and it has aged very well.

So does kompare.
