Marc, any display-continuation-backtrace on roadmap?

and another thing I'd like to point out with this example: I find really difficult to debug the produced code. This is probably because GambitJS doesn't simply transpile the source code but uses the target language as a host for its virtual machine which has its own semantics.
I tried to use Marc Feeleys code to mimic OO style in scheme for prototypes:
; OO (define (new constructor . args) (let ((obj (create-object constructor args))) (lambda (method . args) (call-method obj method args))))
; Prototypes (define (proto constructor . args) (lambda (method . args) (call-method constructor method args)))
(define console (proto 'console)) (console log:)
Error: /out.js:935 g_r1 = g_host2scm(g_r1[g_r2.toString()].call(g_r1)); TypeError: Cannot call method 'call' of undefined
Question:
- I would like to find out the value of "console". But what makes more
sense: Debugging the value "console" in the c platform of the js platform?
- How can you debug the javascript code? Alone the line "g_r1 = g_host2scm(g_r1[g_r2.toString()].call(g_r1)); "
is somehow mindblowing to me. You seem to reach out to scheme again from the generated code. I cannot follow this...

hi I have a the following problem: Initially I was looking for a simple way to write code on several platforms with scheme as the "reference platform". This is more difficult then I thought because most of the target languages have libraries that are build with an OO model. That leaks into the platform neutral source code, so that you write scheme but with OO in mind. Now I see a next problem, that of Javascript making extensive use of "prototyping", again a specific model that has to be ported to other languages.
So my question is, how would you express prototyping in a platform neutral way, so that you can (hypothecally) use the source code also for target languages that don't support prototyping.
Hopefully I don't make this much more complicated than it is. Ben _______________________________________________ Gambit-list mailing list Gambit-list@iro.umontreal.ca https://webmail.iro.umontreal.ca/mailman/listinfo/gambit-list
