How to use git rerere (or similar) for automatic resolution of "Submodule merge conflict"s?

Question

I'm trying to rebase a branch B over a branch A, but one of the newest commits in A deletes one folder replacing it with a git submodule.

After running git rebase A, git stops at every single commit of B (about 200) asking me to resolve conflicts. Then I run git mergetool and I get:

Submodule merge conflict for 'isolate':
  {local}: submodule commit 0b28bb5dc58c86f38729a6f06c235bc564033556
  {remote}: deleted
Use (l)ocal or (r)emote, or (a)bort?

I tried to enable git rerere by running git config --global rerere.enabled 1 and I did call git rerere after having "resolved" (by just typing L).

The problem is: by looking in the .git/rr-cache/ folder I can see that it has recorded one resolution, but it is about the only time (in over 20 resolutions) where I did have to really resolve a conflict.

Maybe rerere doesn't record this type of resolution? If that's the case, how could I do it?

Answer 1

At first I thought it would have been too tedious to do:

git mergetool
# type "l", type "enter"
git rebase --continue

but then I did this:

echo "l" | git mergetool && git rebase --continue

and it was a lot faster, so I just did it for all commits.

However, if anyone finds it, I'm still interested in a better solution :)
