Re: Org and Hyperbole

[Bill Burdick]

Sure:

(defun bill/restore-calc-point (result)
  (when bill/calc-point
    (goto-char bill/calc-point)
    (setq bill/calc-point nil))
  result)

(advice-add 'hmouse-function :filter-return 'bill/restore-calc-point)

If my recalc function matches, it sets bill/restore-calc-point to a marker like this:

(setq bill/calc-point (make-marker))

Since it's normally nil, the advice normally just ignores it.

Could you provide an example of that function advice?
