3.4 Notices

In busy channels you might not be interested in all the joining, parting, quitting, and renaming that goes on. You can omit those notices using C-c C-o.

You can control which notices get omitted via the rcirc-omit-responses variable. Here’s an example of how to omit away messages:

(setq rcirc-omit-responses '("JOIN" "PART" "QUIT" "NICK" "AWAY"))

Notice that these messages will not be omitted if the nick in question has recently been active. After all, you don’t want to continue a conversation with somebody who just left. That’s why rcirc checks recent lines in the buffer to figure out if a nick has been active and only omits a message if the nick has not been active. The window rcirc considers is controlled by the rcirc-omit-threshold variable.
