indent textarea

[Inge Bylemans]

Hi,

When I put the :indent option to true in with-html-output-to-string, the
textarea is filled with spaces, even when it is not empty, a new line start
with spaces behind it. Is there a way to put :indent to true without side
effect on my textarea?

Thanks
Inge

(fmt "<textarea></textarea>") should do the trick.

Thanks for the quick response

Where should I put that?
Now this is what I have:
(:textarea :name "comment" :rows 3 :cols 50 (princ comment))

Thanks

What is the PRINC supposed to do there?

[Inge Bylemans]

The princ is for entering the data from comment variable in the textarea,
like :value for a input field. I don't know how else to get the data to be
shown.

Reading the documentation might help in this case:

Look at STR, ESC, and FMT. Your PRINC will only work if the stream
CL-WHO is currently writing to is *STANDARD-OUTPUT*.

Yes, I'm aware of that. I personally don't mind as I only use the
:INDENT option for debugging.

Something like this (untested):

(defmethod who:convert-tag-to-string-list :around ((tag (eql :textarea)) attr-list body body-fn)
(let ((who::*indent* nil))
(call-next-method)))

See <http://weitz.de/cl-who/#convert-tag-to-string-list>.

What I do is to wrap the textarea in another with-html-output without
:indent t, e.g.

(with-html-output-to-string (s nil :prologue t :indent t)
(with-html-output (s)
(:textarea :name name
:rows rows
:cols cols
(esc (or value "")))))

Cheers,
