The Sex language
Sex is a S-expressions language, which transpiles to C.
Sex is also Chicken, since all source processing and compile-time computations are written in Chicken.
And Chicken is R5RS Scheme.
Compilation and usage
First, get yourself a Chicken. Second, some Chicken deps.
Install Chicken Eggs
By the way, there's a way to make Chicken install eggs non-globally. Refer to the documentation for more info: https://wiki.call-cc.org/man/5/Extension%20tools#changing-the-repository-location
chicken-install fmt getopt-long brev-separate
Compilation
make
Usage
You'll also need a C compiler, so pick any.
cat hello-world.sex | sexc > hello_world.c
cc hello_world.c -o hello_world
Example
Here is an example, demonstrating what Sex source looks like, and what it compiles too. An avid reader also shall notice how we call Chicken procedures in Sex source.
The Sex source:
(include stdio.h)
(define (foo)
"Hello from Chicken code!\n")
(pub fn int main ((int argc) (char **argv))
(puts "Hello from Sex!")
(var (array char 512) name)
(puts "What is your name?")
(scanf "%s" &name)
(printf "Hello, %s!\n" name)
(printf ,(foo))
0)
The resulting C source:
#include <stdio.h>
int main (int argc, char **argv) {
puts("Hello from Sex!");
char name[512];
puts("What is your name?");
scanf("%s", &name);
printf("Hello, %s!\n", name);
printf("Hello from Chicken code!\n");
return 0;
}
Features
Full C interoperability
Just (include "Your/Favourite/Library.h") and use it as you would
have is C.
For hardcore fans of traditional Lisp naming convention,
Sex offers automatic unkebabification of all symbols, i.e. no more
ugly GL_ARRAY_BUFFER s in your code, they may be written in their
proper form: GL-ARRAY-BUFFER.
Auto typedef for structs
Probably harmless idk.
Use an established environment for development
As Sex is S-expressions, you always have Emacs with paredit as your best option.
