In elisp buffers, I use outline-mode in order to manage headings similarly as in org-mode. But when I jump to a bookmark which points to a hidden part of a buffer (because it is below a folded heading), the point ends up at the lowest visible heading which contains the bookmark position.

How can I unfold the corresponding part of the buffer and jump to the actual position of the buffer?

In org-mode however, the problem does not occur: we have the desired behavior.

  • When you say, "In org-mode...the problem does not occur", what do you mean? When you do what in Org mode? – Drew Oct 2 '18 at 21:32
  • I mean: when I jump to a bookmark which points to a hidden place in an org-mode buffer, then the corresponding part unfolds. – Joon Kwon Oct 4 '18 at 17:32

If you use Bookmark+ then you can add a bmkp-jump tag to any bookmark, to carry out any action just after that particular bookmark location is jumped to.

Give this tag a value that is a function, which then is called whenever the tagged bookmark is visited. Any Lisp-readable function value is allowed: a symbol or a lambda expression.

For example, to display Hello! when a bookmark is visited you can use this on that bookmark in the bookmark-list display:

T v bmkp-jump RET (lambda () (message "Hello!"))

That prompts you for the name of the bookmark to add that jump-function to as the value of tag bmkp-jump.

T v is bound in the bookmark-list display to command bmkp-set-tag-value. Elsewhere, the command is bound to C-x p t v. It adds a value to a tag that has none, or it changes the current value of a tag.

The function that is the value of a bmkp-jump tag is called just after the the standard hook bookmark-after-jump-hook is invoked. You can use this tag to invoke functions that are specific to individual bookmarks; bookmarks can thus have their own, extra jump functions.

So you just need a function that unfolds/unhides the current bit of text that you want to show. Use that in place of the function shown above. Try function outline-show-entry, for example.
