[Chicken-users] Scheme Code beautifier
Is there a 'Scheme Code beautifier' where I can call within emacs to tidy up existing code with correct indentations? ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Chicken wouldn't compile otherwise, with an error for apply-hack. Ugh. Apple isn't what it used to be anymore... Damn. Is there a way to detect the correct processor type on this thing? cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Thanks Jim. -Dave On Tue, Nov 30, 2010 at 12:20 AM, Jim Ursetto zbignie...@gmail.com wrote: I swear this was documented in the README, but I can't find it now. Anyway, instead of changing the Makefile, you just need to pass ARCH=x86-64 to the make command, like: make PLATFORM=macosx ARCH=x86-64 Sorry for the inconvenience.

Re: [Chicken-users] Scheme Code beautifier
Sure Joe, you can use indent-region, which is bound to M-C-\. It won't change your linebreaks, but it will reindent your code. 2010/11/29 Joe Python jopyt...@gmail.com: Is there a 'Scheme Code beautifier' where I can call within emacs to tidy up existing code with correct indentations? ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Hi,
I was hoping to get some help with the c++ hello world example
below. I apologize for the question -- I'm currently learning both
Chicken and C/C++ at the same time. So far Chicken seems much easier
than the other Lisps I've tried. Thanks for the effort and great
documentation on this implementation -- it's much appreciated.

If I do the following with C everything works out ok:
*pun.c:
#include stdio.h
void pun(void)
{
printf (To C, or not to C: that is the question.\n Or is it?\n);
}
*pun_module.scm:
(module pun_module (test_pun)
(import chicken scheme foreign)
(define pun_fun (foreign-lambda void pun))
(define (test_pun)
(pun_fun)))
*compile:
gcc -c pun.c csc-4.6.0 -s pun_module.scm pun.o
*at repl:
,l pun_module.so
(import pun_module)
(test_pun)
When I try this:
*pun_cpp.cpp:
#include iostream
using namespace std;
void pun_cpp (void)
{
printf(Hello World!);
return;
}
*pun_module.scm:
(module pun_module (test_pun)
(import chicken scheme foreign)
(define pun_fun (foreign-lambda void pun_cpp))
(define (test_pun)
(pun_fun)))
*compile:
g++ -c pun_cpp.cpp csc-4.6.0 -s -c++ pun_module.scm pun_cpp.o
I get the following:
new-host:chicken daviddreisigmeyer$ g++ -c pun_cpp.cpp csc-4.6.0 -s
-c++ pun_module.scm pun_cpp.o
pun_module.cpp: In function ‘long int stub6(long int)’:

I'm just guessing here, I don't know that much about FFI in chicken,
but I suspect you need to use:
extern C void pun_cpp (void)
when declaring a routine to be used from a C++ file by Chicken.
Otherwise the linker munges the name to support C++ function
overloading, and Chicken can't find it.
