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,
