[cl-who-devel] Newbie confusion
by Vamsee Kanakala 17 Nov '06

Hi, I suspect this has got to do with not properly understanding what gensym does, but I think this should work, but I'm only getting empty <li> elements from the list-items function. Where am I going wrong? (defun list-items () (let ((=value= (gensym))) (loop for =value= to 15 collecting `((:li (write-to-string ,=value=)))))) (defmacro show-errors () `(with-html-output (*standard-output*) (:div :id "errorExplanation" (:ul ,@(list-items))))) Thanks, Vamsee.

[cl-who-devel] CL-WHO transformation rule not working?
by Nico de Jager 14 Nov '06

Hi It seems that the last transformation rule (and example) for attribute values described in CL-WHO's documentation is not working. I am using: LispWorks 5.0 for Linux (Debian Sarge) CL-WHO-0.6.2 HUNCHENTOOT-0.4.9 E.g. (defun logon-page-html () ;logon-action) (with-html-output (*standard-output*) (:html (:head (:title "test")) (:body "Some text" (:table :border "3" ; Going to change this! (:tr (:td "1-1") (:td "1-2"))))))) gives the following in 2 browsers: Some text 1-1 1-2 html: <html><head><title>test</title></head><body>Some text<table border='3'><tr><td>1-1</td><td>1-2</td></tr></table></body></html> While: (defun logon-page-html () ;logon-action) (with-html-output (*standard-output*) (:html (:head (:title "test")) (:body "Some text" (:table :border (+ 1 2) ;Substituted (+ 1 2) for "3". (:tr (:td "1-1") (:td "1-2"))))))) only gives the following in the same browsers: >1-11-2 html: ><tr><td>1-1</td><td>1-2</td></tr></table></body></html> The output of both cl-who:show-html-expansion and cl-who:with-html-output appear correct in the listener, though: CL-USER 11 > (cl-who:show-html-expansion (*standard-output*) (:html (:head (:title "test")) (:body "Some text" (:table :border (+ 1 2) (:tr (:td "1-1") (:td "1-2")))))) (LET ((*STANDARD-OUTPUT* *STANDARD-OUTPUT*)) (PROGN NIL (WRITE-STRING "<html><head><title>test</title></head><body>Some text<table" *STANDARD-OUTPUT*) (LET ((#:G4088 (+ 1 2))) (COND ((NULL #:G4088)) ((AND (EQ #:G4088 T) (EQ CL-WHO::*HTML-MODE* :XML)) (PROGN (WRITE-STRING " border='border'" *STANDARD-OUTPUT*))) ((AND (EQ #:G4088 T) (EQ CL-WHO::*HTML-MODE* :SGML)) (PROGN (WRITE-STRING " border" *STANDARD-OUTPUT*))) (T (PROGN (WRITE-STRING " border='" *STANDARD-OUTPUT*) (PRINC #:G4088 *STANDARD-OUTPUT*) (WRITE-STRING "'" *STANDARD-OUTPUT*))))) (WRITE-STRING "><tr><td>1-1</td><td>1-2</td></tr></table></body></html>" *STANDARD-OUTPUT*))) It seems that only the output of the last "write-string" is sent to the browser for the second example. Thanks. Nico
