Common Lisp + OpenGL: Hello World

A simple lisp file that runs a tiny OpenGL program that you can make live edits to using Emacs and SLIME.

Requirements

1. SDL2
2. Emacs
3. SBCL
4. SLIME (M-x package-install<RET>slime<RET>)
5. Add (setq inferior-lisp-program "/run/current-system/sw/bin/sbcl") to your ~/.emacs. (or whatever the path to sbcl is)
6. Quicklisp (Common Lisp package manager)

Usage

1. Open hello.lisp in emacs
2. Run slime in emacs
3. Run (ql:quickload "sdl2") and (ql:quickload "cl-opengl") in the newly created CL-USER repl. They'll be loaded if on your computer already, or downloaded if not.
4. C-c C-k to compile + load the file
5. run (main) in the REPL to begin
6. make changes to the source file (like vertex colours) and type C-c C-k
   again to live reload
