Re: Footnote tooltips (an attempt)

[Juan Manuel Macías]

I answer myself to comment a couple more things on this question of
footnotes and tooltips. I think my approach is quite poor, and also when
it comes to files with many notes, it takes a long time to create or
update the list of tooltips. So I think I'll give up on' footnote
tooltips. If what it is about is being able to see the content of a
footnote quickly, I have written this other simpler function, which
displays the content of a footnote at point, in the echo area. Since
`<C-h .>' (`display-local-help') is not very useful in a footnote
reference, I recycle the shortcut for my function, if the context is a
footnote reference. I share it here, in case it is useful to someone.

┌────
│ (defun my-org-footnote-show-content ()
│   "Displays the content of a footnote at point, in the echo area"
│   (interactive)
│   (if (not (equal (org-element-type (org-element-context)) 
'footnote-reference))
│       (error "Not on a footnote reference!")
│     (let* ((elt (org-element-context))
│          (label (org-element-property :label elt))

│                       (from (org-element-property :contents-begin e))
│                       (to (org-element-property :contents-end e)))
│                  (buffer-substring-no-properties from to)))))
