ediff: replace refined differences

ediff: replace refined differences

[Martin Rubey]

Hello!

I love ediff.  I'd love it even better, if there was a way to copy
refined differences selectively:

currently, ediff lets me copy a difference region from one buffer to
the other by pressing a or b.

Frequently, I do not want to have the whole difference region copied,
but only parts of it.  Is there a nice way to do that?

Thanks,

Martin

AFAIK, there is no way to, say, incrementally or selectively copy parts of a
single diff from, say, A to B.

You can, however, quit ediff, narrow the buffers to the parts you're interested
in, and then use ediff again. Just a workaround, but it can sometimes be useful,
especially if ediff doesn't quite see things the way you do. ;-)

Perhaps someone else has another suggestion.

well, the problem is really that I do not want to quit and restart
ediff, find the difference region, etc...

I guess the best thing for me would be a command
"split-difference-region", that makes every (refined) difference a
single difference region.  Maybe a step into this direction would be
to make every line in the current region a region on it's own.  This
would already be quite helpful, I guess.

How are the difference regions computed?

Perhaps if ediff has some kind of preprocessing hook, you can somehow refine.

Not helpful, I know, but such a hook would have other uses.

Hi,

did you look at

  ediff-regions-wordwise	      <menu-bar> <tools> <compare> <ediff-regions-wordwise>
     Run Ediff on a pair of regions in specified buffers.
  ediff-windows-wordwise	      <menu-bar> <tools> <compare> <ediff-windows-wordwise>
     Compare WIND-A and WIND-B, which are selected by clicking, wordwise.

already ?

Wow, that's just perfect!  Thank you so much!  And now indeed I love
ediff even better.  How can one live without it!
