setting env vars from scheme post 0.7 #273

can't set env vars from scheme in aot code since 0.7

JimKuhn commented 8 years ago

It seems to work for me on Linux (at least) (?).

I added this to an aot module:

(impc:aot:do-or-emit
  (define EnvTest
    (lambda ()
      (sys:set-env "dummy_env" "ABC"))))

I then loaded it (post aot-compile) and executed:

(EnvTest)
($ (printf "%s\n" (getenv "dummy_env")))

ABC

Hi Andy, what do you mean by "can't set env vars from scheme in aot code" - do you mean the scheme wrappers don't work? Because obviously plain scheme (as per Jim's example) is never AOTed.

I'm talking about an xtlang closures captured variables. not the shell's environment variables.

(bind-func test (let ((x:i64 0)) (lambda () (* 2 x))))

;; this works OK for non-ato'd code but not for aot lib (println (test)) (test.x 5) (println (test))

;; this always works ($ (println (test))) ($ (test.x:i64 10)) ($ (println (test)))

Don't fuss though guys, the note is for me to chase when I have time.
