I do believe you see it what you say, but I didn't see what you
say... (✿╹◡╹) -- so yes, now it works, thanks.
I have removed `id' and `ignore' and there are no compiler warnings
and there is for now no impact how I see that. That comes due to
various testing, I have actually started it that way, there was no ID,
then I messed something up and addedd ID and now you see more, and I
removed it from bunch of functions. For now it works.
(defmacro when-tabulated-id (table &rest body)
(declare (indent 2) (debug t))
;;(ignore id)
`(if id
(progn
,@body)
(if (or (eq ,table 'any)
(string-equal ,table rcd-current-table))
(let ((id (tabulated-list-get-id)))
(if id
(progn ,@body)
(message "Did not get ID")))
(message "This function is for table `%s' only" ,table))))
