* The Sex language
|
||||
Sex is a S-expressions language, which transpiles to C.
|
||||
|
||||
* Compilation and usage
|
||||
Sex is written in Chicken Scheme, so first you'll need to get yourself
|
||||
a Chicken.
|
||||
|
||||
** 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
|
||||
|
||||
* 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.
|
||||
|
||||
** COMING SOON: Polymorhpism
