I have two files, `a.rkt` and `b.rkt`: ;; a.rkt #lang racket (provide foo) (define-syntax (foo stx) ;; Do some compile-time side effects here… #'(begin))
;; b.rkt #lang racket (require "a.rkt") (foo) The `foo` macro defined in `a.rkt` does some side effects, and expands to `(begin)`. When `b.rkt` is opened in DrRacket, there is no arrow drawn from `foo` to the require clause, and the require clause is marked as unused (red background when hovering it. How can I get the arrow from `foo` to "a.rkt", while keeping the same semantics? * If I change `foo` so that it expands to `(begin-for-syntax)`, then the arrow is correctly shown, but the macro can't be used in expression contexts. * If I change `foo` so that it expands to `(void)`, then the arrow is correctly shown, but it changes the semantics (whether #<void> values are displayed or not during execution depends on the language) * The only solution I found is to change `foo` so that it expands to `(define dummy (void))`. Since the macro is hygienic, the `dummy` definition is inaccessible. It does feel a bit clunky though, is there a better solution? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
