Hello Per,
I just noticed that if I put my macros inside a R7RS define-library,
then it get these warnings:
(define-library (foo)
(export define-foo define-bar)
(import (kawa base) (kawa lib syntax))
(begin
(define-for-syntax known (list))
(define-syntax define-foo
(lambda (stx)
(syntax-case stx ()
((define-foo a)
(begin
(set! known (cons (list #'a 0) known))
#'(define a (list)))))))
(define-syntax define-bar
(lambda (stx)
(syntax-case stx ()
((define-bar a n)
(identifier? #'a)
(if (assoc #'a known)
#'(set! a (cons n a))
#'(begin
(define-foo a)
(set! a (cons (list n 0) a))))))))))
(import (foo) (srfi 64))
(test-begin "t")
(define-foo x)
(test-equal '() x)
(define-bar x 1)
(test-equal '(1) x)
(test-end)
$ kawa test.scm
test.scm:13:14: warning - no declaration seen for known
test.scm:13:45: warning - no declaration seen for known
test.scm:21:27: warning - no declaration seen for known
%%%% Starting test t (Writing full log to "t.log")
# of expected passes 2
It'd be nice if there's a way to not have warnings show up.
Thanks again!
Duncan.
