Question

I was reading this question and the answers are a convoluted mess (timer function REALLY?)

In any case, I don’t care about recreating these buffers, as that is trivial. But these buffers contain information which should never be deleted, and because they don’t have associated filenames, they are usually killed without confirmation.

I do have a solution in mind, but I want to see if someone has a more “canonical” one.

jtahlborn provided the most canonical solution, except the “keep-buffers” package is showing its age has some issues:

1. You had to specify whether all protected buffers are to be buried and erased (erased buffers can be recovered with `undo’) when killed, or just buried when killed.

2. member is reimplemented as find-in-list less efficiently.

3. Helper functions that didn’t really help.

I made the the protected-list an alist that associates regexp to erase-action, and deleted the useless (IMO) code. By default, “scratch” is erased when killed, “Messages” is never erased or killed.

i use the keep-buffers utility.
