Sure!

You're counting the number of summary items, not the number of notifications. I suspect you want to do the latter, so you would need to do count += parseInt(s._counterLabel.get_text(), 10). If all you want to do is the former, just use Main.messageTray._summaryItems.length.

magcius: I want to count the number of conversations with new messages. I don't want “hello” followed by “how are you?” to appear as 2. _summaryItems also contains other stuff, so the count that comes out is wrong.

Your code will also count any source which has multiple collapsed notifications. Try: for (let path in Main.telepathyClient._chatSources) { let source = Main.telepathyClient._chatSources[path]; if (source._pendingMessages.length > 0) count++; }

But with my code I also get the red notification when somebody pings me on xchat.
