The away-notify client capability allows a client to specify that it
|
||
|
|
would like to be notified when users are marked/unmarked as away. This
|
||
|
|
capability is referred to as 'away-notify' at capability negotiation
|
||
|
|
time.
|
||
|
|
|
||
|
|
This capability is designed to replace polling of WHO as a more
|
||
|
|
efficient method of tracking the away state of users in a channel. The
|
||
|
|
away-notify capability both conserves bandwidth as WHO requests are
|
||
|
|
not continually sent and allows the client to be notified immediately
|
||
|
|
upon a user setting or removing their away state (as opposed to when
|
||
|
|
WHO is next polled).
|
||
|
|
|
||
|
|
When this capability is enabled, clients will be sent an AWAY message
|
||
|
|
when a user sharing a channel with them sets or removes their away
|
||
|
|
state, as well as when a user joins and has an away message set.
|
||
|
|
(Note that AWAY will not be sent for joining users with no away
|
||
|
|
message set.)
|
||
|
|
|
||
|
|
The format of the AWAY message is as follows:
|
||
|
|
|
||
|
|
:nick!user@host AWAY [:message]
|
||
|
|
|
||
|
|
If the message is present, the user (specified by the nick!user@host
|
||
|
|
mask) is going away. If the message is not present, the user is
|
||
|
|
removing their away message/state.
|
||
|
|
|
||
|
|
To fully track the away state of users, clients should:
|
||
|
|
|
||
|
|
1) Enable the away-notify capability at negotiation time.
|
||
|
|
|
||
|
|
2) Execute WHO when joining a channel to capture the current away
|
||
|
|
state of all users in that channel.
|
||
|
|
|
||
|
|
3) Update state appropriately upon receiving an AWAY message.
