Hi,
By googling the Web for an XML-RPC implementation in Common Lisp, I found S-XML-RPC and other one for Corman Lisp. I'm glad that S-XML-RPC is now part of Common-Lisp.net.
By the way, looking at the Corman Lisp API for XML-RPC, I found interesting that it have the ability to define a standard function embedding an XML-RPC call. How about implementing this kind of thing in S-XML-RPC? I wrote the following lines of code:
(defmacro define-xmlrpc-method (name args &key url method) `(defun ,name ,args (xml-rpc-call (encode-xml-rpc-call ,method ,@args) :url ,(puri:uri-path url) :host ,(puri:uri-host url) :port ,(cond ((puri:uri-port url)) (t 80)))))
(define-xmlrpc-method get-state-name (state) :url #u"http://betty.userland.com/RPC2" :method "examples.getStateName")
(define-xmlrpc-method get-time () :url #u"http://time.xmlrpc.com/RPC2" :method "currentTime.getCurrentTime")
? (get-state-name 41) "South Dakota"
? (get-time) #<XML-RPC-TIME 20040617T10:47:31>
I rely on the great PURI package to parse URL. Quite straightforward. Of course, we should also wrap and unwrap some type convertions not to see anything about the XML-RPC types. I guess the function should also accept HASHTABLEs to be converted in XML-RPC structs.
What do you think?
