require and use for-syntax function crashes raco cover #89

Closed SuzanneSoy closed 9 years ago

SuzanneSoy commented 9 years ago

When require and use a function for-syntax, its body is not marked as covered in DrRacket, and it crashes the raco cover tool.

#lang racket

(module m racket
  (provide bar)
  (define (bar)
    (+ 1 1))) ;; (+ 1 1) is not marked as covered in DrRacket and crashes raco cover

(module main racket
  (require (for-syntax (submod ".." m)))
  (define-syntax (foo stx) #`#,(bar))
  (foo)) ;; Although this prints 2.

Running raco cover file.rkt produces this error message

Ahah, The version of cover that fixes this has not been pushed to the PKG server get (its still a tad unstable).

If you install cover directly from the github master branch then this error should disappear---or you can wait a week or two for this to make it to covers release branch.
