undo and folding

undo and folding

[Samuel Wales]

Very often, I will hit undo, only to find that all of the changes it
makes are hidden in a folded subtree.  Combined with the lack of a
non-buggy true redo, this makes things very confusing.

Is there a way to fix this?

That happens to me quite often, too.

Where is emacs' redo buggy?  Any non-undo command after undo followed by
undo will undo your latest undo.  Isn't that easy?

I guess you could add a before advice to `undo', that calls `show-all'.

Not that I know.  Maybe some advice around the undo function,
to make at least point visible after an undo command?  This is
untested, and may be incomplete since it does not take into
account the range in the buffer that was really affected by the undo.
But it may already help:

(defadvice undo (after org-undo-reveal activate)
   "Make point and context visible after an undo command in Org-mode."
   (and (org-mode-p) (org-reveal)))

redo.el corrupts the buffer.

emacs doesn't have a command that goes forward in the undo history.

It doesn't?

C-_ is undo and if you set a mark with C-SPC then C-_ is redo for me.

NOTE: I have no idea what redo.el is of if I use it.

Try undoing far, then farther, then less far, and copying from each
place and pasting into a buffer, using the default emacs undo.
