How to configure an alert in Textual when someone joins a channel

Suppose you’re staff in a support channel which isn’t very frequented by other users, and you want Textual to make a sound and show a notification (i.e. trigger a highlight) whenever someone joins that support channel.

The chat filter can trigger some actions when certain things happen, like user joins channel #foo, and we are going to use the /notifybubble and /notifysound commands to alert us about this event.

  1. Go to Preferences -> Add-Ons -> Chat Filter and click the + in the lower left to create a new filter
  2. on the Filter tab, give the filter a name (example: Alert for joins on #foo), then copy paste this into the Filter Action field:
    /notifysound Glass
    /notifybubble %_channelName_% %_senderNickname_% joined %_channelName_%
  3. on the Channels tab, select Specific Items and select the channel(s) you want to watch for joins in the list that opens
  4. on the Events tab, make sure only User joined channel is selected
  5. The last three tabs Sender, Notes and Advanced are completely empty

Whenever someone joins your channel now, you will get a notification and a sound:

Bonus feature: If you click the notification, it will automatically take you to that channel!
