I was describing what the code is supposed to do, and what it currently does on
my system.
I am not quite sure of the reason why it doesn't work on your system. Is the
config the following?
(add-hook 'LaTeX-mode-hook
(lambda () (add-hook 'after-change-functions
#'preview-point-buf-change nil t)))
Note the hook name `LaTeX-mode-hook`, not `LaTeX-mode` as I mistakenly had in
the very first version of the package (in case you copied it from then).
If so, I might be able to pin down the reason if you check the following:
- What is the value of `major-mode` in your document?
- Are there any messages in "Messages" after editing the code.
- Is the outdated preview greyed out?
- After editing the equation, if you call preview-at-point, is the preview
updated?
- After editing the equation, if you press: M-x
(preview-point--preview-at-point (point) (current-buffer))
is the preview updated?
Thanks,
