MACROLET inside HTM

[Volkan YAZICI]

Hi,

I've been trying to use MACROLET in HTM with no success:

(with-html-output (*standard-output*)
(:div
(macrolet ((foo (bar) `(:div ,bar)))
(htm
(foo "baz")
(foo "moo")))))

Here's the fully macroexpand result of the above form:

(LET ((*STANDARD-OUTPUT* *STANDARD-OUTPUT*))
(PROGN
(WRITE-STRING "<div>" *STANDARD-OUTPUT*)
(MACROLET ((FOO (BAR)
`(:DIV ,BAR)))
(HTM (:DIV "baz") (:DIV "moo")))
(WRITE-STRING "</div>" *STANDARD-OUTPUT*)))

I will be appreciated if anybody would help me to figure out how to
use MACROLET inside HTM bodies.


Regards.

You currently can't do that due to the simplistic way CL-WHO expands
the body of WITH-HTML-OUTPUT, and I think there's no easy portable way
to fix that. (Patches welcome, of course.)

You can, however, define your own tags instead:
