Run Racket code blocks within Org mode buffers:

#+BEGIN_SRC racket
#lang racket

(printf "Hello World")
#+END_SRC

#+RESULTS:
: Hello World

Simplest case of running a code block is supported :)

It is possible to set the racket language to be used within the buffer by setting :lang. This can be useful to set the lang to be used throughout the same Org buffer by setting a global property:

#+property: header-args :lang racket

#+BEGIN_SRC racket
(printf "Hello world")
#+END_SRC

#+RESULTS:
: Hello world

Tables and variable passing via :var not supported yet.

• Get Racket mode
• Enable Racket code blocks execution and path to racket binary

  (org-babel-do-load-languages
        'org-babel-load-languages
        '((racket . t)))
  
  (setq org-babel-racket-command "/usr/local/bin/racket")
      

• Put ob-racket.el within the contrib/lisp/ folder of your Org mode distribution
• That should be it :)
