echo '(* 10 (1+ 2))' | sc returns (10*1+(2)); As you can see, this is a bug. There's a similar problem with 1- as well. I understand that the 1+ and 1- functions don't exist in sph-sc. But, it would be good to raise an error if they are used. The error checking can be based on the fact that C function names can only start with an alphabetic character.

Another way, and I think the better way, is to simply implement 1+ and 1- as macros. 1+ and 1- are not supported by C, but they are so common in scheme and are handy to have.

Cheers!

Hi,
SC finally runs on my machine, but the whole installation process was pretty annoying, which I make Guile responsible for. I received great support from the creator of 'sc, but still, the process took time and during this time I had the opportunity to reflect why I so desperately want to install that exotic software.

Especially when I consider the fact, that I already installed 'sc' earlier some month ago, maybe even years. When I remember correctly I was not convinced of the sc compiler because of its weak macro support. Now that I see multiple references on that in project, I'd like to make a new try. And in addition to that I find it encouraging that sc is still in active development, because I think it is the only compiler that I know of that is happy with just providing some thin layer of syntactic sugar for the target language. Because that's it what I'm looking for a start. And then I hope for a capable macro system.
Sorry for misusing the 'issues' section as message board.

I report (again) a problem with the installer script which I try to run on macos.

If in case macos is even supported I give you the error:

Hi,

I would like to initialize an int variable in its declaration, like int n = 1. Currently, I can only do this with two forms---a declare and a set---like so

(declare n int)
(set n 1)

Is there some way to do this with just a declare form---something like (declare n (int 1))?

Thanks!

Hi,
I try (again) to install or at least run sph-sc on mac. It doesn't work. For one I could no install sph-lib with the script, so copied sph-lib manually into a load path. I'm not sure if I did it successfully, but what seems to work it importing sph-libs on the repl.
Now with sph-sc the "problems" begin with the exe/install script. My mac doesnt like some of the 'cp' commands options, and then the install script tried to install the modules in read only directory.
So in the end, I manually copied the sph/lang into the load path. But still exe/sc is still not running, and while try to debug the problem, I comment out almost all of the 'sc' comment, so it looks like this

#!/usr/bin/env guile
!#
(use-modules (sph) (sph lang indent-syntax))
;  (sph lang scheme) (sph string)

this happens when I run it

/sc.bin
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-auto-compile argument to disable.
;;; compiling /Users/ben/[...]/sph-lib/sph-sc/exe/./sc.bin

Hi,

Negation doesn't seem to work correctly. (- (+ x y)) gets translated to ((x+y));. Notice the missing negation.

Cheers!

Hi there,
Sadly the install script fails run on my machine, due an error with the cp command.

sudo exe/install
Password:
cp: illegal option -- -
usage: cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file target_file
       cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file ... target_directory

This is comming from Guile I guess, but still maybe there is a workaround for sph-sc ...

Ben
