restoring window configuration after vc-ediff

restoring window configuration after vc-ediff

[Eric S Fraga]

I often use vc-ediff instead of vc-diff to see the differences between
the working copy and a previous version.  Works very well.  I have just
one quibble: when I quit ediff, the previous version buffer is still
displayed.  Is there an easy way to restore the window configuration to
what it was when vc-ediff is invoked?

I could probably advise the function but would rather use existing
functionality if possible.

Thank you,
eric

The easiest way of leaving your window configuration untouched by a
command is to invoke that command in a separate frame.

Well, sure, but it definitely adds friction... currently, a simple key
binding invokes vc-ediff.  I would have to include creating and deleting
a frame to the process.  And this interferes to some degree with the
window (x parlance) manager.

For vc-ediff, there's (generally) no benefit in having the previous
version buffer remain visible after the ediff operation is finished.

I guess I'll advise the function instead making use of
save-window-excursion.

thank you,

If you are using Emacs 28 and later, there's the "C-x 5 5" prefix to
try.

Ah, yes, that helps reduce friction.  Thank you.
