Evaluating forms inside of with-html-output-to-string

[Andrew Pennebaker]

According to the documentation, with-html-output-to-string can evaluate Lisp
forms. In my experience, this is not the case.

(cl-who:with-html-output-to-string (*standard-output* nil :prologue nil
:indent t)
(:p (concatenate 'string "abc" "def")))

Should return

"<p>
abcdef
</p>"

but it actually returns

"<p>
</p>"

Specs:

- Lispbox CCL 1.6
- Mac OS X 10.6.6 and Ubuntu 10.10 Maverick

Try:

(cl-who:with-html-output-to-string (*standard-output* nil :prologue nil :indent t)
(:p (str (concatenate 'string "abc" "def"))))

i.e., enclose the lisp form generating the string with (str )

Thanks for suggesting (str).

The correct code (without importing the cl-who package):

(cl-who:with-html-output-to-string (*standard-output* nil :prologue nil
:indent t)
(:p (cl-who:str (concatenate 'string "abc" "def"))))

The current docs <http://weitz.de/cl-who/#str> don't say anything about
(format nil) not working inside of with-html-output-to-string; they just say
that (str) has no binding. A simple notice would aid new Lispers, myself
included.

The current docs don't say anything about (format nil) not working inside of
with-html-output-to-string; they just say that (str) has no binding.

The section "Syntax and Semantics" explains this in detail. I guess
you just didn't read that...
