;;; A collection of functions to aid in the make |
|
;;; http-requests to the Ritherdon REST API. This project is help me |
|
;;; learn Common Lisp. So, there is not much emphasis on being too |
|
;;; strict on best practices and defensive coding. |
|
|
|
;;; NOTE: The Ritherdon REST API is part of an art exhibition at time |
|
;;; of writing (29/06/2021). You will need to check if the server is |
|
;;; still running if you want to run this code. |

;; All the data provided by the Ritherdon REST API is in JSON. Becuase |
|

|
