Is this a windows machine?
Assuming so, if you start DrRacket from a windows command.com shell
window and then, after it gets busy hit control-c, do you get any
output in the shell window?

Hi,
Does anyone know if racket can be deployed in the cloud? (Is there a cloud
service that support racket?). And if yes, how? :)
Thanks,

There are many things that might be meant by the cloud, but on the
simplest interpretation, the answer is definitely yes. For example,
Eric Hanchrow (offby1) run the irc bot rudybot [1] from an Amazon
EC2 Linux image.
There are also two Racket bindings to the AWS service api, in various
states
Would a structure type property be a viable alternative? Example:
;;
#lang racket/load
(module a racket
(define-values (prop:S S? S-ref) (make-struct-type-property 'S))
(provide S?)
(define-struct s (a b)
That's a bug. I've looked into it a little bit, enough to say that I
can't fix it this morning. Sorry.

It should now be visible at that URL; I'd made that repo private for

It does, however, support printing which is nice.

Ok.
Hi all,
I'm using web-server/templates to generate text, and the data in variables I
reference in the template include s-exps that may, in some cases, contain
image% objects. I want it to render the image%s as plain text; even just the
string IMAGE or similar would be adequate.
So, my

I wasn't able to find in the Racket documentation a string function
that replaces substrings in a string based on the content of the
substring. Something similar to Python's string replace method .

I find that my intuitions about what might or might not be too slow
