Any way to access dock labels from apps?

[carlos-gtz]

I would like to add a menu with slack notifications unread 🤔 The easiest would be to do some API access through REST... but if we already have the notification in the dock app... then that would be better as I wouldn't need to access Slack API and polling to get the notifications.

Is there a way to access the Dock and read the label on an app (slack app) to use it in any cool way?

You can read the AXStatusLabel of the dock item via the Accessibility API.

See: http://www.hammerspoon.org/docs/hs.axuielement.html

Thank you 🙏

I came up with this code:

Dock = hs.axuielement.applicationElement('Dock'):attributeValue('AXChildren')

for _, v in pairs(Dock[1].AXChildren) do
  if v:attributeValue('AXTitle') == 'Slack' then
    local label = v:attributeValue('AXStatusLabel') or '0'
    print(label)
  end
end

Thank you for your help.

You could probably add a break after the print to escape the for loop too.
