I find I need to fully expand the buffer to get the context in the way I am currently doing it (e.g. getting the lines around the element), but I would like to put the buffer back to the way it was when I am finished. This is not done with the usual macros like save-excursion, save-restriction, etc... Is there a way to do this other than a temp buffer? thanks, -- Professor John Kitchin Doherty Hall A207F Department of Chemical Engineering Carnegie Mellon University Pittsburgh, PA 15213 412-268-7803 @johnkitchin http://kitchingroup.cheme.cmu.edu ^ permalink raw reply [flat|nested] 4+ messages in thread

Is folding not just implemented with invisible overlays? If so, why do you need to change this to get context? You can try setting buffer-invisibility-spec temporarily. For example, run this function in a folded org-mode buffer. (defun temp () (interactive) (message "invisibility spec stuff") (let ((buffer-invisibility-spec '())) (message "sitting") (sit-for 5)) (message "done")) It unfolds everything but having the display engine ignore all overlays/text properties. If you want to do this interactively, and you will forgive the plug, my own package, lentic, would enable you to do this. You can open up a second buffer which has the same text as the first, but could be folded completely independently of the original. At the moment, you only get one copy, but I'll expand that to any number at some point. When you're finished kill the copy, and all the changed folding goes with it.

I was having some issue in selecting contex using commands that grab what is visible. So for things inside a folded section it was not grabbing the right context. I solved it by doing something similar to what you describe, i.e. a tempbuffer. lentic looks pretty interesting. Phillip Lord writes: > You mean programmatically?

I'd be interested to know if it works or not. Although I wonder whether the commands that you are using really should be obeying visibility context.
