This is a general issue with tabulated-list-mode -- there's no way to get back to the original order after sorting. That is, the caller will put the data in `tabulated-list-entries', and it'll be displayed in that order. When sorting, tabulated-list-mode will then sort on the data in a column, and that destructively modifies `tabulated-list-entries'. So to get back to the original order, we can't rely on re-sorting -- we really have to know what the original order was, which means that we have to store that somewhere. I've now done so in Emacs 28 (stashing it in a hash table instead of making a copy of the list itself, in case that has had elements removed in the meantime). It takes up some extra memory, but it's not done until the user issues a sorting command, so I think it should be OK. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
