Oh, interesting.
I see.
Just popped open the Ediff code and there is a significant amount of effort put into ignoring whitespace. Like, it's not a shortcoming per se that it can't show this content but rather a deliberate onslaught to avoid it at all costs. The author must have been really annoyed by whitespace. 😂
I mostly use
(ediff-buffers)
in my day-to-day work in Spacemacs to compare two regions that I've narrowed to indirect buffers, and, interestingly, it does show me diffs that contain whitespace-only changes and prints the following to the echo area:https://preview.redd.it/587vplu76e1c1.png?width=1896&format=png&auto=webp&s=e3d559ae695972f62865560b96f23953b4b26027
I did a quick test with other ediff functions bound in Spacemacs, and
ediff-windows-linewise
has the same behavior, butediff-windows-wordwise
does not -- it completely ignored diffs that were whitespace only and there was not even##
binding available in that ediff session.When browsing the code, I found a local variable named ediff-whitespace (which u/doolio_ has already pointed out here in reply to you, actually), which is curious:
(
\240
is Unicode symbol for nonbreakable whitespace.)I wonder whether this variable can be set to nil.
PS:
Apparently word splitting is configurable with ediff-forward-word-function ?
