To show this use this code
;;;; Eval this defun, place point at the end of the buffer and call
;;;; it. It inserts text and an overlay in the buffer.
;;;;
;;;; Play with the different buffer invis specs. It looks like the
;;;; overlay is not affected by the specs.
(defun my-test-inv ()
(interactive)
(let ((b "some invis parts")
(ovl (make-overlay (point) (point))))
(add-text-properties 5 10 '(face secondary-selection
font-lock-face highlight
invisible (my-invis))
b)
(insert ";;;;;;;;;;;; START OF INSERTED TEXT+OVERLAY
;;;;;;;;;;;;;;;;;;;;\n")
(insert ";; Text: " b "\n")
(move-overlay ovl (point-max) (point-max))
(overlay-put ovl 'before-string (propertize "Overlay: " 'face
'secondary-selection))
(overlay-put ovl 'after-string b)
))
;;;;;;; Test these, none affects the overlays `before-string' or `after-string':
;; (setq buffer-invisibility-spec '((my-invis . t) t))
;; (setq buffer-invisibility-spec '((my-invis) t))
;; (setq buffer-invisibility-spec '(t)) ;; This does not work, bug??
;; (setq buffer-invisibility-spec t)
;; (setq buffer-invisibility-spec '(other-invis))
;;;;;;; Delete overlays here:
;; (dolist (ovl (overlays-in (point-min) (point-max))) (delete-overlay ovl))
