Hi,
How do I add text properties to org elements? In my particular case, I
want to echo tooltips when I move my cursor over an org link (or other
org elements for that matter). To do this, I need to add the properties
point-left and point-entered to all org-links. How do I do that?
Thanks for any ideas.

Not sure if this is the best method:
o go to (point-min)
o loop
(goto-char (cdr (org-element-link-successor (point-max))))
(org-element-link-parser) and extract :begin and :end values from
the returned list
Untested (mostly) - termination, error handling (and who knows what
else) left to the interested reader...

I was afraid of this. I think the safest way of not screwing up the
parsing and error handling would be to implement it as a patch to
org-activate-*-links in org.el.
I guess I should give some background info. Lately (>1yr), I have been
using Emacs exclusively from the terminal. In a gui, hovering the mouse
over a link shows you the target as a tooltip. If you turn tooltip mode
off, it is shown in the echo area; but this is only in a gui frame.
I think it is very important to show where a link goes in a document. I
consider it good a safety practise (e.g. web browsers). Hence my
attempt to implement this feature. :)

I was taking a shot at this again. This is where I stand at the moment:
- I want to add the properties `point-left' and `point-entered' to all
links where the target is invisible (hidden), so for the moment I'm
focusing on bracket links.
- I tried to patch `org-activate-bracket-links' to this end; in the let*
bind I extended the list of properties with like this:
(let* ((hl (org-match-string-no-properties 1))
(help (concat "LINK: " (save-match-data (org-link-unescape hl))))
(ip (org-maybe-intangible
(list 'invisible 'org-link
'keymap org-mouse-map 'mouse-face 'highlight
'font-lock-multiline t 'help-echo help
'point-left sa-echo-tooltip ; <-- my addition
'point-entered sa-echo-tooltip ; <-- my addition
'htmlize-link `(:uri ,hl))))
(vp (list 'keymap org-mouse-map 'mouse-face 'highlight
'font-lock-multiline t 'help-echo help
'point-left sa-echo-tooltip ; <-- my addition
'point-entered sa-echo-tooltip ; <-- my addition
'htmlize-link `(:uri ,hl))))
;; rest of the code is unchanged
)
With this "new" org-activate-bracket-links, when I open an Org file, I
see some bad fontification (e.g. keywords are in default face) and the
invisible parts of backet links are visible. As in: instead of showing
this is a link
(in org-link face)
I see
[[http://www.example.com/target][this is a link]]
(the http part is in org-link face, the rest in default)
I tried to run edebug-defun on org-activate-bracket-links before opening
the org file, but that doesn't trigger the step by step execution of
org-activate-bracket-links I was expecting. I tested with
`get-text-property' interactively, my properties were not added to the
links. So I'm wondering what am I doing wrong? Better yet, is there a
better way to do this?
Thanks for any help or ideas.
Cheers,

Add salt to taste or cookup your own recipe based on the hints here.
(add-hook 'org-mode-hook
(lambda nil
(setq-local default-text-properties

(defun org-link-entered-maybe (op np)

I can't see the properties. This is what I tried:
(add-hook 'org-mode-hook
(lambda nil
;; (setq-local default-text-properties
;; '(point-entered org-link-entered-maybe point-left org-link-entered-maybe))
(setq-local default-text-properties
'(point-entered sa-echo-tooltip point-left sa-echo-tooltip))
))
Where sa-echo-tooltip is my function. Then I open the following Org
file:
------8<---------8<----------
#+TITLE: Test adding text properties to links
#+STARTUP: showeverything
* Links
- [[https://www.google.com][Google]]
- https://en.wikipedia.org/wiki/Main_page
------8<---------8<----------
With my cursor on the 2 links, I see the following with describe-char:
There are text properties here:
face org-link
font-lock-multiline t
fontified t
help-echo "LINK: https://www.google.com"
htmlize-link (:uri "https://www.google.com")
keymap [Show]
mouse-face highlight
org-no-flyspell t
There are text properties here:
face org-link
fontified t
htmlize-link (:uri "https://en.wikipedia.org/wiki/Main_page")
keymap [Show]
mouse-face highlight
org-no-flyspell t
As you see there is no mention of point-left or point-entered.
Any ideas?

point-entered and point-left properties should have different values.
See
(info "(elisp) Special Properties").

With point on the link try this:
M-: (get-text-property (point) 'point-entered)
ps: There could be better way of gettting what you want. Do your own
exploration.

Sorry I think I wasn't clear in my email. I want to echo in the echo
area. So changing the (not 'use-echo-area) to 'use-echo-area did it.

I had read that, but I think I misunderstood it the last time I read it.
After your message when I read it again, I see that they should be
different :-p.
Thanks a lot. I'll experiment some more.
