Remember to cover the basics, that is, what you expected to happen and what in fact did happen. You don't know how to make a good report? See
https://orgmode.org/manual/Feedback.html#Feedback Your bug report will be posted to the Org mailing list. ------------------------------------------------------------------------ With point on an entry containing a scheduled timestamp like “<2025-01-22 Wed +1d --1d>”, calling `(org-entry-put nil "SCHEDULED" (org-entry-get nil "SCHEDULED"))' results in the removal of the delay cookie "--1d". This doesn’t happen if there is no repeater or if the delay cookie is of the form "-1d". I’m assuming this is not the intended behavior. (As long as the current VAL of PROP is not problematic in some sense, I’d expect “(org-entry-put nil PROP (org-entry-get nil PROP))” to leave VAL intact.) As far as I can tell, the issue can be traced back to the way `org--deadline-or-schedule' parses the ‘time’ argument: the variable ‘repeater’ is set to “+1d -1d” if the TIME argument to `org--deadline-or-schedule' is “+1d -1d” but set to “+1d” if it is “+1d --1d”. I’m guessing the wrinkle is in the regex here: “(string-match "\\([.+-]+[0-9]+[hdwmy]\\(?:[/ ][-+]?[0-9]+[hdwmy]\\)?\\)" time)” but I’m not sure how to modify it. (The first captured group is “+1d -1d” when the input string is e.g. “<2025-01-22 Wed +1d -1d>” but “+1d” when it is “<2025-01-22 Wed +1d --1d>”.)
