Hi all,
As the Racket Web Server doc shows, we can define URL dispatching rules as
follows:
(define-values (blog-dispatch blog-url)
(dispatch-rules
[("") list-posts]
[("posts" (string-arg)) review-post]
[("archive" (integer-arg) (integer-arg)) review-archive]

Is it possible to have a macro bound to an identifier with wildcards in it?
So, for example, a macro (@*) that would be used for (@x) and (@y), where
the symbols x and y are available during expansion.
Or is this something that would have to be done at the reader level? ie,
(@ ...) is the macro,

The idea is to introduce a kind of soft skip for tokens. Ragg will accept them
in the grammar but leave them out of the syntax object for the production.
I've had the opportunity to discover that it's really hard to parse syslog
messages properly. Especially since I want to accept the traditiona

A nice puzzle. Now Ryan added #literal-datums that's of course
the way to go, but here is a solution.
First define a syntax class that matches a literal datum.

Folks,
I am trying to embed racket into a C program, and have a module which uses
"define-match-expander" (in conjunction with match).
The attached scripts seem to show an inconsistency between a module
that has been declared with declare_modules(...) and one that has been
imported with scheme_n
