* 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 [[https://call-cc.org][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~

** Compilation
~make~

** Usage
You'll also need a C compiler, so pick any.
#+begin_src
cat hello-world.sex | sexc > hello_world.c
cc hello_world.c -o hello_world
#+end_src

* 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:
#+begin_src
(include stdio.h)

(define (foo)
  "Hello from Chicken code!\n")

(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)
#+end_src

The resulting C source:
#+begin_src
#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;
}
#+end_src

* 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 writted in their
proper form: ~GL-ARRAY-BUFFER~.

** Use an established environment for development
As Sex is S-expressions, you always have Emacs with paredit as your
best option.
