Yet another Lisp markup language
Home Page: https://edicl.github.io/cl-who/
Consider for example:
(who:htm
(:input :type "text" :name "title" :value "My cat's birthday"))
; Renders <input type='text' name='title' value='My cat's birthday' />
This would break since '
is not escaped to '
as required by the XML spec. I think for attributes it generally makes sense to always use escape-string
-minimal, since I don't see a situation where you'd want to be able to inject arbitrary strings into the tags attribute list.
I guess this can't really be changed now without breaking a lot of existing code depending on who already escaping its attributes, but a setting to change this behavior would be nice.
At
http://weitz.de/cl-who/#*html-no-indent-tags*
In
"The list of HTML tags that should disable indentation inside them even when indentation is requested. The initial value is a list containing only :pre and :texarea."
Would you please consider adding a :description option to your system definition of cl-who?
As in title. I noticed slime integration exists for Parenscript: https://parenscript.common-lisp.dev/reference.html#section-slime-integration
Please, make a new release. The latest release in quicklisp suffers from symbol collision in
(who:with-html-output-to-string (who:str) (:a :href ""))
which is really hard to debug.
When a WITH-HTML-OUTPUT is compiled with non-standard print syntax (e.g. print-base 16), that is somehow captured/closed over at compile-time such that even e.g. wrapping the form in WITH-STANDARD-IO-SYNTAX does not help. This is quite unexpected behaviour and also confusing. I'm guessing what happens is in CONVERT-ATTRIBUTES the CONSTANTP attributes are formatted with tilde A at compile-time.
I'd suggest making such compile-time constant folding optional (presumably it's a speed optimization feature?), and also wrapping it in a compile-time WITH-STANDARD-IO-SYNTAX.
In both ccl (development version 1.10) and sbcl (1.1.14) if I run:
(asdf:operate 'asdf:test-op :cl-who)
I get an error:
got an unexpected error: error while parsing arguments to DEFMACRO WITH-HTML-OUTPUT-TO-STRING:
unknown keyword: :ELEMENT-TYPE; expected one of :INDENT, :PROLOGUE
I am still a novice in common lisp matters and not sure if test-op is even supposed to work with cl-who. Just reporting it in case it is. I can do further diagnosis if you suggest.
(let ((x "hi"))
(with-html-output-to-string (s)
(:a :href (str x))))
=> "<ahi href='hi'></a>"
Take the following as an example:
(defmacro with-html (&body body)
`(cl-who:with-html-output-to-string (*standard-output* nil :prologue t)
,@body))
(defmacro html-standard-page (&body body)
`(with-html (:body ,@body)))
(defmacro test-g (id)
`(:table (:tr (:td ,id))))
With this code, I would expect (html-standard-page (test-g "15"))
to output something like:
`
15 |
Why doesn't it? Instead I get warnings that :td
etc. are not defined. What am I doing wrong?
I hope this is an OK place to post this, as I wasn't sure where I should go with support questions. Thank you.
The following code:
(let ((v "18") (st nil))
(with-html-output (st nil)
(:div :href v)))
Outputs:
(let ((v "18") (st nil))
(with-html-output-to-string (st nil)
(:div :href v)))
returns: "
"(edit - closing parenthesis for balance)
When installing CL-WHO via Quicklisp, version 0.11.1 is installed. This version does not include :HTML5 support. If possible, please release 0.11.2 (or something similar) with support for HTML5 (which is in the git repo anyway) for Quicklisp.
Thanks!
The first one reportedly prevents weblocks from working:
(cl-who:with-html-output (*standard-output*) " ")
throws an error.
the fix is here: http://paste.lisp.org/display/131510
The second one is an issue with misplaced declarations, here's a description:
http://paste.lisp.org/display/131509
and a fix:
http://paste.lisp.org/display/131510#1
I'm not sure if this is a bug or I'm doing something silly, I suspect the latter, but I'm curious to know the cause of this. I'm trying to create an h4 tag with some text in it and then a link, like this:
<h4>Foo <a href="/bar/21">➕</a></h4>
The code I'm using is such:
(with-html-output-to-string (*standard-output* nil)
(:h4 (fmt "Foo ~A"
(htm (:a :href (format nil "/bar/~A" 21) "➕")))))
This produces the following output, with an extra '>' mixed in there, hings are all out of order, and some duplication occurs.
<h4><a href='/bar/21'>➕</a>Foo >➕</a></h4>
I've tried all varieties of (str)/(htm)/(format)/(fmt) that I can think of.
Any guidance would be appreciated.
Hi, I think there is a problem during the expansion because the symbols esc
fmt
and str
are expanded twice.
e.g.
(with-html-output-to-string (s) (:a :onclick (str "Test")))
expand to "<aTest onclick='Test'></a>"
but I think it makes more sense to expand into "<a onclick='Test'></a>"
.
Is this supposed to work the way it is working currently:
(let ((a "hello"))
(with-html-output (var (make-string-output-stream))
(htm (:a a))))
;=> "</a>"
;expected <a>hello</a>
If so, why and what is the work around?
In "(defmacro with-html-output-to-string..." at
http://weitz.de/cl-who/#with-html-output-to-string
is the text "(with-output-to-string (,var ,string-form :elementy-type ,element-type)" which, perhaps, should be "
(with-output-to-string (,var ,string-form :element-type ,element-type)".
I think the text "elementy" is a typo.
"Ciao, Edi"
(a pun on a song by The Cult, named "Edie (Ciao Baby)")
Thank all of you very much for your work, and for making it available.

"CL-WHO will usually try not to insert any unnecessary whitespace in order to save bandwidth. However, if indent is true line breaks will be inserted and nested tags will be indented properly. The value of indent - if it is an integer - will be taken as the initial indentation. If it is not an integer it is assumed to mean 0. Value of HTML-NO-INDENT-TAGS controls which tag-contents are excempt from indentation..."
