I didn't know about scribble/bnf -- that's plain PERFECT for my needs.
Thanks a lot!

While `scribble/bnf' is a better approach, you could use
@(define IS (tt "::="))
@(define OR (tt " | "))
@racketblock[
@#,IS '()
@#,OR (cons )
]

Awesome. You guys make people wish they had a problem to solve using Racket! :)

Have you tried the BNF grammars in scribble section:

Hi,
I want to typeset a BNF with Scheme-like syntax highlighting.
eg:
@racketblock[
::= '()
| (cons )
]
except that the pipe `|' causes problem. I figured out that I can do the above
with @verbatim|{...}| but then I lose the syntax highlighting ('() as a value,
brown parentheses).

It would probably help if there was a racket starter package
Some clever students should show that the old ways of our people are not
lost... and spend their (US) Thanksgiving weekend hacking Racket on
"http://aichallenge.org/";.
Besides the hack value and educational value, I think one can reasonably
imagine that placing well in this competition woul
There's a bug in Racket 5.2 that prevents Whalesong from compiling. Try
either a pre-release version of Racket, or Racket 5.1.3.

Hi everyone,
Whalesong 1.9 corrects a few issues, particularly the use of external
CSS stylesheets on the Android phone browsers.

Changes:
* Added view-has-attr? and remove-view-attr.
