This module attempts to keep track of what MUC chat rooms users have joined. It’s not very useful on its own, but can be used by other modules to influence decisions.
Rooms joined and the associated nickname is kept in a table field
rooms_joined on the users session.
local jid_bare = require"util.jid".bare; module:hook("message/full", function (event) local stanza = event.stanza; local session = prosody.full_sessions[stanza.attr.to]; if not session then return -- No such session end local joined_rooms = session.joined_rooms; if not joined_rooms then return -- This session hasn't joined any rooms at all end -- joined_rooms is a map of room JID -> room nickname local nickname = joined_rooms[jid_bare(stanza.attr.from)]; if nickname then session.log("info", "Got a MUC message from %s", stanza.attr.from); local body = stanza:get_child_text("body"); if body and body:find(nickname, 1, true) then session.log("info", "The message contains my nickname!"); end end end);
XEP 45 § 7.2.3 Presence Broadcast has the following text:
In particular, if roomnicks are locked down then the service MUST do one of the following.
If the user has connected using a MUC client (…), then the service MUST allow the client to enter the room, modify the nick in accordance with the lockdown policy, and include a status code of “210” in the presence broadcast that it sends to the new occupant.
This case is not yet handled.
