Dear List,
I am trying to use the Gambit-Scheme JS-backend. I am using the 4.7.0 release. I compiled the following program (obtained from this list) with: gsc -c -target js fib.scm ;; ===================== fib.scm ===============================
(declare (standard-bindings) (extended-bindings) (not safe) (fixnum) (block))
(define (fib n) (define (fib n) (if (< n 2) n (+ (fib (- n 1)) (fib (- n 2))))) (fib n))
(println (fib 30))
;; EOF
I tried to run it:
node fib.js
/home/alexshendi/sources/gambit/fib.js:42 print(obj); ^ ReferenceError: print is not defined at Gambit_println (/home/alexshendi/sources/gambit/fib.js:42:3) at Object.Gambit_bb1_println [as println] (/home/alexshendi/sources/gambit/fib.js:66:3) at Gambit_bb4__20_fib (/home/alexshendi/sources/gambit/fib.js:119:31) at Gambit_bb3__20_fib (/home/alexshendi/sources/gambit/fib.js:104:12) at Gambit_trampoline (/home/alexshendi/sources/gambit/fib.js:21:10) at Object.<anonymous> (/home/alexshendi/sources/gambit/fib.js:252:1) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12)
Now I have the following questions:
* Apparently the generated code is for another JS implementation (Spidermonkey?)? * How do I access e.g. console.log() from scheme? * I tried to use the standard Scheme functions "display" and "newline" from fib.scm, but that didn't work. How do I use them? * Where do I find more info on the JS backend?
Many thanks in advance for your help.
Best Regrads,
