First of all let me thank you for your terrific software. The availability of your software (and others too) has really helped my picking up lisp.
You're welcome... :)
For the past few days I've been reading c.l.l (but not posting, because I don't know nearly enough to participate in any of the current discussions). My background with lisp began this winter when I started a course at my University in scheme. Since then I've been trying to get going with common lisp and web programming (since that is what I do during the summer at my job).
Good luck! I'm sure you'll have fun with CL.
But anyway, on to my question: How can I get a template parsed with html-template to come up with as a tbnl page? I'm working off the tbnl-test example so I have just created a new function add-artist' and added it to dispatch table, but I can't figure out how to get it to output the results of parsing a template.
Something like
(defun add-artist () (with-output-to-string (*default-template-output*) (fill-and-print-template template/printer values)))
should do it. Note that FILL-AND-PRINT-TEMPLATE prints its output to the stream *DEFAULT-TEMPLATE-OUTPUT* and TBNL wants a string returned by the handler, so the code above makes sure everything printed to this stream ends up in a string which is returned by the function.
This assumes that ADD-ARTIST is a handler, not a dispatcher.
Also another issue I am having is get-parameters, get-parameter, post-parameters and post-parameter all don't seem to work. Even with something like(defun add-artist () (with-html (:html (get-parameters)))) does not work (the way I'd expect it to at least, it produces only the prologue and <html></html> even when passed parameters).
WITH-HTML is the macro which uses CL-WHO from the test suite, right? If that's the case you must wrap the form (GET-PARAMETERS) with something that asks CL-WHO to include it in the output, otherwise it'll only be evaluated for its side effects. One of
(str (get-parameters)) (esc (get-parameters)) (fmt "~S" (get-parameters))
should do it.
Does that help?
Cheers, Edi.
