Yes there’s a macro for that, macro-case-target.

(include “~~lib/_gambit#.scm”)

(macro-case-target ((c) ...) ;; when target is C ((js) ...) ;; when target is JavaScript (else ...)) ;; otherwise

Hi,

I want to expand a macro based on what backend (c, js, ...) is currently used to compile the file.

Does the backend install a cond-expand symbol that I can reference or else is there a way to know what is the current backend from my macro?

Thanks,
