Hi all -
I have now implemented the pattern matching/transforming algorithm of a
macro expander (no hygiene yet) for a single macro expansion call. The next
step is to figure out how to apply the macro expanders recursively "in
order".
For example, let's say we want to expand the following:

I like to use field names like in the example above. Can I do this in racket?
What I have done most recently is to define a struct with a low-level
constructor with positional
Hi there,
In Common Lisp I can define something like this:
(defvar *db* nil)
(defun make-book (&key author title)
(list :author author :title title))
(defun add-record (book) (push book *db*))
(add-record (make-book :author "John Grisham" :title "The Client"))
I like to use field names li

This relies on a Latex macro named \identity being defined earlier in
Define a Scribble function like this:
(define (exact . items)
(make-element (make-style "identity" '(exact-chars))
items))
(provide exact)

In the HTML output, can I do more than just choose a new CSS style?
(If yes, can you point to the proper place in the manual?)
I know how to change the styles in the CSS file, but for the embedding code
below, I need to output HTML too.
Ideally, I'd like to write something a la:
@html/pdf{}{}

You can just set up a new command and give it different
implementations in a style.tex and for the HTML output. There is a
section on this in the docs I believe.

Here is an expansion on Noel's answer.
When the compiler sees a

it creates code that allocates a vector of three words:
-- one that says "I am not a vector, but a book struct"
-- one that holds the author value
-- one that holds the title value
