How to create notifications after updates?

Hi! First of all, thanks for the awesome package!
I'm trying to implement desktop notifications after the feeds are updated showing the number of new entries. However I couldn't find a good way to implement that. An advice around elfeed-update doesn't work since the update is done asynchronously. So far I'm using the elfeed-update-init-hooks and elfeed-update-hooks hooks for that (please check below). But that's more like an workaround because I need a keep a global count and because elfeed-update-hooks runs for every feed.
Do you see a better way for doing that? Thank you very much!
(setq ~elfeed-count 0)
(defun ~elfeed-save-count ()
"Save the number of entries before an update."
(elfeed-db-ensure)
(setq ~elfeed-count (elfeed-db-size)))
(add-hook 'elfeed-update-init-hooks #'~elfeed-save-count)
(defun ~elfeed-notify-new (url)
"Show a notification after an update if there are new entries."
(let* ((count (elfeed-db-size))
(new (- count ~elfeed-count)))
(when (> new 0)
(alert (format "From %s" url)
:title (format "Elfeed: %d new %s"
new (if (= new 1) "entry" "entries"))
:icon "internet-chat"))
(setq ~elfeed-count count)))
(add-hook 'elfeed-update-hooks #'~elfeed-notify-new)sp1ff commented
Hi Marcello, not sure if this is what you're looking to do, but I
detect when the update has completed by checking
`(elfeed-queue-count-total)` in my update-hook. Something like:
(defun s1pff/elfeed/update-hook (_url)
(when (eq (elfeed-queue-count-total) 0)
(do-the-update-thing)))
hth,
