This is a Common Lisp implementation of the XMPP RFCs. Please see http://common-lisp.net/project/cl-xmpp for more information.
Example -
(require :cl-xmpp)
(defvar *connection* (xmpp:connect :hostname "jabber.org"))Alternatively, use xmpp:connect-tls if you loaded cl-xmpp-tls.
Note that for XMPP servers which do not have the same hostname
as the domain-part of the user’s JID, you will have to pass that
in. e.g. for Google Talk -
(defvar *connection* (xmpp:connect-tls :hostname "talk.google.com"
:jid-domain-part "gmail.com"))
(xmpp:auth *connection* "username" "password" "resource")…or pass :mechanism :sasl-plain, :digest-md5 or sasl-digest-md5
if you loaded cl-xmpp-sasl or cl-xmpp-tls.
Send someone a message
(xmpp:message *connection* "username@hostname" "what's going on?")Then sit back and watch the messages roll in…
(xmpp:receive-stanza-loop *connection*)
<MESSAGE from=username@hostname to=me@myserver>
[....]…or use xmpp:receive-stanza if you want just one stanza
(note it will still block until you have received a complete
stanza)
That’s it. Interrupt the loop to issue other commands, e.g.
(xmpp:get-roster *connection*)…or any of the other ones you may find by looking through cl-xmpp.lisp and package.lisp to see which ones are exported.
If you wish to handle the incoming messages or other objects simply
specify an xmpp:handle method for the objects you are interested in
or (defmethod xmpp:handle (connection object) ...) to get them
all. Or alternatively specify :dom-repr t to receive-stanza-loop
to get DOM-ish objects.
For example, if you wanted to create an annoying reply bot -
(defmethod xmpp:handle ((connection xmpp:connection) (message xmpp:message))
(xmpp:message connection (xmpp:from message)
(format nil "reply to: ~a" (xmpp:message object))))
