The problem isn't with defining the function, the problem is with
making a contract for it.
I can define the function fine, I just don't know how to write a
contract for it. I used make-keyword-procedure to define the
function, but is there something like make-keyword-procedure-
contract?
Yes, it is a package now. But I found it is still more convenient to install
manually.

Is there a version of send-generic that takes a keyword list and kw-
argument list like send/keyword-apply? I already searched the
documentation, but maybe it's there under a different name, and on a
different page from send-generic. If not, would it be possible to
define something like th

If you don't mind providing a little more information on what's slow, I'd
make an attempt to speed it up. Specifically, what operations are you doing
(scrolling, typing, something else?) and what seems slow (refreshing?)
Also: what version are you using?
Thanks,

Matthias has good points about why the base Racket language does not do
this, but if you want to do language experiments, or if you have really
unusual practical requirements, you can still use Racket as a language
platform...
You could define your own "#lang" variant of Racket that stores the

No. The 'pp' idea probably dates back to the age of Lisp-machine repls when MIT

Scribble allows programmers to create their own 'styles' and
within a CSS style you can certainly refer to JS components.
Search for 'style' in the docs (e.g. raco doc style) and peruse
the scribble notion of style.

Racket's editor is very slow. Therefore, the background expansion produces
an annoying flicking in the Macintosh. Of course, it produces an annoying

would like to learn how to disable background expansion in the Macintosh.

I noticed that MIT Scheme has the "pp" procedure which prints the source
code of a given function. Is there an equivalent way to do this in Racket?
More generally, I'm looking to normalize nested procedures to their most
rudimentary expressions.
For example:
(define (something? x) (> x 3))

Hi,
Does scribble support generating a combination of HTML/CSS/javascript
for some simple dynamic content? I'm thinking of writing some
programming articles/tutorials, and was wondering if there was any
support for the following:

This is a bit vague. Can you clarify the question with a concrete example?

The match pattern (? number? n) matches number and
binds it to n.

1
I'd like to write (match 1 [n:num n]) instead.
Since there is no define-identifier-match-expander I have
tried to make (match 1 [(n:num) n]) work. I need a hint.
