Meld is capable of loading many files at once (in tabs).

However when used with git difftool, Git will ask if you want to view each file (which can be slow and annoying to have to keep opening and closing meld).

Is there a way to load meld with every file in a tab?

(I realize why this default was chosen, diffs bay be very big, however I would find the ability to do this very handy).

    Have you tried git difftool --dir-diff as per this answer? (Haven't personally tried it with Meld but someone commented that it works and it does work for me with kdiff3.) – Steve Chambers Sep 12 '16 at 11:20

    Its handy (and worth adding as an answer), but I still need to open each file manually. – ideasman42 Sep 12 '16 at 12:49
  • Have added this as an answer. When you say "open each file manually" do you mean just clicking on each file to see what the changes are? As mentioned in the answer, kdiff3 has a pane that will show all the files that have changes (in a tree structure). – Steve Chambers Sep 16 '16 at 8:29

I'm not currently able to comment on meld as don't have it installed but for kdiff3, the git difftool --dir-diff command works nicely, e.g. to compare any two remote branches:

git difftool --dir-diff origin/branch1..origin/branch2

For kdiff, this lists all the files that have changed in one pane and the differences for a selected file are shown in another pane - would imagine meld would do something similar. It can take a while before the diff comes up if there are a lot of changes.

    works with meld as well. – Hassan Nadeem Feb 6 '18 at 15:47

Something similar can be achieved with git-diffall (it's not a built-in, you have to follow that link and install it). Its syntax is just like with git diff, but it opens the difftool in directory comparison mode, showing all modified files on one screen. You can double-click them to open comparisons in tabs.
