Hello list,
I am trying to do namespace-require to a submodule, racket complains about
unknown module, as below:
$ cat go.rkt
#lang racket
(module food racket
(provide apple)
(define apple "pie"))
(parameterize ([current-namespace (make-base-namespace)])
(namespace-require ''food)
(eval 'apple))
$ racket go.rkt
require: unknown module
module name: #<resolved-module-path:'food>
context...:
Simply namespace-require food in toplevel has the same issue:
#lang racket
(module food racket
(provide apple)
(define apple "pie"))
(namespace-require ''food)
Finally, the above code works if I type them in the interactive mode.
I tried namespace-attach-module, and I understand why that failed: it
didn't work because (module food racket ...) wouldn't instantiate the
module, and a instantiated module is what namespace-attach-module wants.
What is it that I am missing in above code to require a submodule in a
namespace? Why is submodule food invisible here?
