;;; Commentary:
|
|
;; `System' is just a state monad which holds the state of the editor.
|
|
;; Each system has to have a `start' function to start the setup process.

|

|
|
;;; Code:
|
|
(require 'fg42/state)
|
|
|
|
|
|
(defun fg42/system-register-cube (name cube)
|
|
"Add the given CUBE with the given NAME to the system.
|
|
|
|
System is a state monad that returns by state-cons"
|
|
(fg42/state-cons 'cubes (cons name cube)))
