The first problem was writing the html to standard output instead of a string, the second problem is that cl-who does not quite work the way you think. What I did was replace as-html with the appropriate with-html-output form and then macroexpand.
Hm - ok - now that you say it ... Obviously the right thing to do. I was looking for Cells misuse anywhere - wrong. It was the CL-WHO side which I did not get right. Oh well....
Give it a try. Meanwhile, this works:
(defpackage #:whofix (:use #:common-lisp #:cells #:cl-who))
(in-package :whofix)
(defmacro as-html (var &body body) `(with-output-to-string (,var) (with-html-output (,var) ,@body) ))
As this is working as-html has to be changed because in CL-WHO there's
(defmacro with-html-output-to-string ((var &optional string-form &key (element-type ''character) prologue indent) &body body) "Transform the enclosed BODY consisting of HTML as s-expressions into Lisp code which creates the corresponding HTML as a string." `(with-output-to-string (,var ,string-form #-(or :ecl :cmu :sbcl) :element-type #-(or :ecl :cmu :sbcl) ,element-type) (with-html-output (,var nil :prologue ,prologue :indent ,indent) ,@body)))
So, we can write:
(defmacro as-html (&body body) `(with-html-output-to-string (*standard-output* nil :prologue nil) ,@body))
Hm - coming back to your remark
the second problem is that cl-who does not quite work the way you think
Well, I think I have understood that I have to output any data via write-string because this is what is to be inserted between tags... Anything else?
Thx anyway!
