🔮 Viewers

The following cell registers the custom viewers. This api is still alpha and subject to change.

(require '[nextjournal.viewer :as v])
(v/register-viewers!
  {:number :cell ;; use the cell viewer for numbers
   :cell #(v/view-as :hiccup
            [:div.inline-block {:class (if (zero? %)
                                         "bg-white border-solid border-2 border-black"
                                         "bg-black")
                                :style {:width 16 :height 16}}])
   :vector (fn [x options]
             (->> x
               (map (partial v/inspect options))
               (into [:div.flex.inline-flex])
               (v/view-as :hiccup)))
   :list (fn [x options]
           (->> x
             (map (partial v/inspect options))
             (into [:div.flex.flex-col])
             (v/view-as :hiccup)))})
