Hello, I’m new to racket language and playing with it’s syntax reading and generating features. What I want to do is a simple translator that reads scheme s-expressions and translates them into ocaml. I’m using `read-syntax’ to get a list of syntax-objects and then recursively translate them into s-expressions that are looking `ocaml-like’:
;; simplified version transform (define (transform stx) (syntax-case stx (require module lambda) ;; and more special forms ((require id) #’(open id)) ((module id expr) #`(module id = #,(transform #’expr))) ((lambda () expr) #`(fun () -> #,(transform #’expr))) ;; …and so on )) The problem is: when I use it in REPL everything works great: > (syntax->datum (transform #’(require AModule))) (open AModule) > (syntax->datum (transform #'(define a (+ 1 2 3)))) (let a = (1 + 2 + 3)) But when I use same procedure on a syntax-object that was read by `read-syntax', I'm getting exception: source.ss::23: require: bad syntax in: (require AModule) I looked at read syntax-object and it looked same as the one I'm making in REPL, so I have no idea where I'm wrong. :( Thanks, Nikita B.
