31;; Tame MUC presence notifications.
32
33;; This patch hides or applies a face to MUC presence notifications in
34;; the MUC chat buffer. To control its behavior, customize
35;; ’jabber-muc-decorate-presence-patterns’. By default it does nothing.
36
37;; ’jabber-muc-decorate-presence-patterns’ is a list of pairs consisting
38;; of a regular expression and a either a face or ‘nil’. If a the
39;; regular expression matches a presence notification, then either:
40
41;; - the specified face is applied to the notification message
42;; - or if the second value of the pair is nil, the notification is
43;; discarded
44
45;; If no regular expression in the list of pairs matches the notification
46;; message, the message is displayed unchanged.
47
48;; For example, the customization:
49
50;; '(jabber-muc-decorate-presence-patterns
51;; '(("\\( enters the room ([^)]+)\\| has left the chatroom\\)$")
52;; ("." . jabber-muc-presence-dim)))
53
54;; hides participant enter/leave notifications. It also diminishes other
55;; presence notification messages to make it easier to distinguish
56;; between conversation and notifications.
