Hi,
Sorry for the delay, does this script fix a bug in WeeChat?
What's the use case where the buffer is not marked as read?

[kindrowboat]

Hey, no problem! I think this is an issue when you're using a weechat relay. Before this script, when I moved off of a buffer, it was still marked yellow/unread. I'd have to switch off and back onto to the buffer to get it to to be marked as read. This is true for only the relay host, I think. I swear I saw a known issue/wontfix for this, but I can't seem to find it now.

OK, for relay (weechat protocol), this is caused by the option weechat.look.hotlist_add_conditions whose default value is ${away} || ${buffer.num_displayed} == 0 || ${info:relay_client_count,weechat,connected} > 0.
So the last condition means if there's at least one client of the weechat relay, always add the buffer to the hotlist, even if it's the current one.
It's done like this because the relay client may not see the same buffer as active, and thus you don't miss any notification in the client.
If needed, you can remove this condition, but then that means the weechat current buffer will not be added to hotlist and not visible in the client.
