Please make it (parameterize ((current-urlencoded-arguments ,args) (current-request ,req)) so that post-var works too. Actually I like a lot this function, which I have extracted from define-http-resource: (define (add-dynamic-resource url thunk) (http:add-resource url (lambda (request args) (parameterize ((current-urlencoded-arguments args) (current-request request)) (let/cc return (let/ respond (http-resource:responder request return) (handle-exceptions exn (parameterize ([http:error-response-handler (http-resource:error-handler exn)]) (http:write-error-response 500 Internal Server Error)) (respond (thunk) Maybe it would be a good idea to expose it directly, would do you think?

RE: [Chicken-users] an ode to Spiffy
Felix, Hm. Could you try this, please: [...] $ ./repltest #; (thread-start! (lambda () (let loop ((i 0)) (print i) (thread-sleep! 1) (loop (add1 i) ; from now on you should still be able to eval expressions... That worked out of the box for me. [This is normally done in srfi-18.scm, but is disabled on Windows. Should this work with cygwin (requires select(2)), I'll disable it exclusively for Windows/MSVC (which doesn't have select(2) on file/stdio fd's)] Please, do so!

It may look a bit silly and ugly, but some time ago I made something that looks like that (if my guess about what LAML is is correct -- couldn't read the papers yet). It's at http://www.inf.ufrgs.br/~mario/english/utils/web-scheme Disclaimer: - I made it without looking for previous work about this topic. So, if some ideas are badly implemented or if there things that just look too silly, it's my fault. - The code is far from being good (horrible, in fact :-)) Originally it was just an attempt to get rid of some even more ugly scripts I use to generate headers and footers to some of my html pages and to use some programming stuff embedded in web pages with a cleaner syntax. Now it's not even that because I didn't convert those pages. :-) Best whishes, Mario ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
