Hello Racketeers!
I just released an early version of my first real Racket project, which extends
Racket to become a 6502 assembler. Thought I would share it here:

The dispatch pattern is special syntax, not an expression, so you need to
write a macro. To get started,
(define-syntax-rule (add-route route method proc)
(dispatch-rules! main-container
[route #:method method (proc)]))
would work. You can get better error reporting if you us
Thanks again, I think I got how to use it now.
Here is my example:
(define-container main-container (hsk-dispatch a-url))
(dispatch-rules! main-container
[("") #:method "get" overview-app])
(dispatch-rules! main-container
[("index") #:method "get" overview-app])
This is great! I'm excited to read more of your book.

Hi,
I recently read Beautiful Racket and I found it very inspiring, so I started my
own Racket project book using Pollen. I'm not a great programmer, but that's
the point.
Please have a look at it at http://users.telenet.be/vincent-nys/index.html.

Are there any particular algorithm you are interested in?
Anyways, back to bindings for GSL. Noel Welsh has bindings for an older
version of GSL.
It could be a starting point for making a new version
