Gibberish

A basic module for IM using the Jabber/XMPP protocol with PLT Scheme.

Protocol Support

Should eventually implement XMPP-Core and XMPP-IM to conform with RFCs 3920 and 3921.

example chat client

(require xmpp)

(define (read-input prompt) (display prompt) (read-line (current-input-port)))

(define (chat) (let ((jid (read-input "jid: ")) (pass (read-input "password: ")) (to (read-input "chat with: "))) (with-xmpp-session jid pass (set-xmpp-handler 'message print-message) (let loop ()
(let ((msg (read-line (current-input-port)))) (send (message to msg)) (loop))))))

possiby interesting extensions to implement.
