[html-template-devel] Loop Quirk "Maybe"
by Leander Gillard 21 Jul '05

21 Jul '05

Hello, I'm developing a web application using a combination of CGI::App, CGI::Template, xmlHTTPreq. The problem I am having is that when I get a return string from my xmlhttpReq request it comes back as expected, I check this like this. alert(t); But when I set the innerHTML of a div immediately after like so. window.getObject(name).innerHTML = t; It removes a beginning chunk of the string when trying to use innerHTML on a select box and just doesn't do anything using innerHTML on a DIV(but the div solution works for FF). It must be noted that if I put the div anywhere outside of the html::template loop it then works in IE. This seems to be IE specific or related. Any and all help would be appreciated. Sincerely, Leander

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.

[html-template-devel] Possibility of changing tag names
by Luis Oliveira 19 Sep '04

19 Sep '04

Hi, First off, many thanks for you great Lisp softwares. They are useful for both using and reading. :-) After seeing the *template-(start|end)-marker* special variables I wondered why not do that same for the TMPL_* tokens. I'm not sure if it's a good idea or not but since it was so trivial to implement I'm sending you a patch in attach. The documention might need further editing. Thanks, -- Luís Oliveira Veras tio, kion mi trifoje http://student.dei.uc.pt/~lmoliv/ diras al vi.

[html-template-devel] question about *default-template-pathname*
by Nicolas Lamirault 10 Sep '04

10 Sep '04

i use html-template in 2 projects i have a macro like this : (defmacro print-template ((page) &body body) `(ml:output-html-page (with-output-to-string (stream) (let ((*default-template-output* stream) (tp (create-template-printer ,page)) ... (fill-and-print-template tp (list :title tile :author author ,@body))))))) and i have a start function which have an argument to set default-template-pathname*, like this : (start-project "/location/of/templates/" file-config) and in start-project : (setf html-template:*default-template-pathname* template-dir) but i have a problem when my 2 projects are loading because each one modify *default-template-pathname* is there a possibility to have a default template directory for each project ? thanks for any help -- Nicolas Lamirault

Here's Jan's answer (he replied to the list but forgot to subscribe) which explains why his code worked in the REPL but not in TBNL. Edi.

This happens because FILL-AND-PRINT-TEMPLATE rebinds *STANDARD-OUTPUT* to the value of *DEFAULT-TEMPLATE-OUTPUT* which is *STANDARD-OUTPUT* (the original one!) by default. I admit that this is an unfortunate design decision which happened mainly because I was too lazy to type. I might chance this in a future release. In other words: All statements like (write-string string) in CREATE-SIMPLE-PRINTER in 'template.lisp' should rather be (write-string string *default-template-output*) instead. That way I wouldn't need the (let ((*standard-output* stream)) rebinding in 'api.lisp'. > Adding a :stream *standard-output* argument to > fill-and-print-template helps in this case.

Perhaps you > could add a simple usage example together with TBNL to the > documentation of one of the packages? All of these should work: (with-output-to-string (*default-template-output*) (with-input-from-string (s "test  one") (html-template:fill-and-print-template s '(:a "1")))) (with-output-to-string (out) (with-input-from-string (s "test  one") (html-template:fill-and-print-template s '(:a "1") :stream out))) (with-output-to-string (out) (let ((*default-template-output* out)) (with-input-from-string (s "test  one") (html-template:fill-and-print-template s '(:a "1"))))) This is also documented here: <http://weitz.de/html-template/#default-template-output> Let me know if this works for you or if you still have problems. Cheers, Edi. PS: I'm sending a copy to the mailing list. Please use the list for bug reports and questions. Thanks.
