How do I write a scheme macro that defines a variable and also gets the name of that variable as a s
- by Jason Baker
This is mostly a follow-up to this question. I decided to just keep YAGNI in mind and created a global variable (libpython). I set it to #f initially, then set! it when init is called. I added a function that should handle checking if that value has been initialized:
(define (get-cpyfunc name type)
(lambda args
(if libpython
(apply (get-ffi-obj name libpython type) args)
(error "Call init before using any Python C functions"))))
So now here's what I want to do. I want to define a macro that will take the following:
(define-cpyfunc Py_Initialize (_fun -> _void))
And convert it into this:
(define Py_Initialize (get-cpyfunc "Py_Initialize" (_fun -> _void)))
I've been reading through the macro documentation to try figuring this out, but I can't seem to figure out a way to make it work. Can anyone help me with this (or at least give me a general idea of what the macro would look like)? Or is there a way to do this without macros?
