;;; Commentary:

;; This package serves as the algorithm interface for Org-srs, allowing
;; the core to be independent of specific algorithms.

;;; Code:

(require 'cl-generic)

(require 'org-srs-property)

(org-srs-property-defcustom org-srs-algorithm nil
  "The spaced repetition algorithm used globally."
  :group 'org-srs
  :type 'sexp)

(cl-defgeneric org-srs-algorithm-ensure (object &rest _args) object)

(defun org-srs-algorithm-current ()
  (apply #'org-srs-algorithm-ensure (ensure-list (org-srs-algorithm))))

(cl-defgeneric org-srs-algorithm-repeat (algorithm args))
