How to run the code

I personally found the combination of Emacs and Slime on top of SBCL gives the best IDE for common Lisp.

With Emacs+Slime+SBCL

Install Emacs using the following

Linux:

sudo apt-get install emacs

Windows & MacOS:

https://www.gnu.org/software/emacs/download.html

Install SBCL (also on Windows and MacOS)

download from here: http://www.sbcl.org/platform-table.html
```
sudo ./install.sh
```

Setup Slime in Emacs

create .emacs in your home folder.

add following to this file:

(require 'package)
(let* ((no-ssl (and (memq system-type '(windows-nt ms-dos))
                  (not (gnutls-available-p))))
     (proto (if no-ssl "http" "https")))
;; Comment/uncomment these two lines to enable/disable MELPA and MELPA Stable as desired
(add-to-list 'package-archives (cons "melpa" (concat proto "://melpa.org/packages/")) t)
;;(add-to-list 'package-archives (cons "melpa-stable" (concat proto "://stable.melpa.org/packages/")) t)
(when (< emacs-major-version 24)
  ;; For important compatibility libraries like cl-lib
  (add-to-list 'package-archives (cons "gnu" (concat proto "://elpa.gnu.org/packages/")))))
(package-initialize)
;; Setting lisp system
(setq inferior-lisp-program "/usr/local/bin/sbcl")
(setq slime-contribs '(slime-fancy))

and then restart emacs and run the following:

M-x package-refresh-contents
M-x package-install RET slime RET

Clone this repo
In Emacs, open slime
```
M-x slime
```
SLIME starts the Lisp system with the current directory taken from the directory where the file associated with the current buffer is. If you want to exit from slime:
```
, sayoonara
```
In slime REPL run:
```
(load "Tester.lisp")
```
