nom

A Clojure library providing some utility-functions and -macros for Om.

Usage

(cancel-event [e])

Runs preventDefault and stopPropagation on event e.

(with-working [target & body])

A utility macro that sets the key :working? to true on target (a Om cursor or owner). Useful to disable forms while some operation (body) is running e.g. in a core.async go block.

defcomponent

A macro just like defcomponent from prismatic/om-tools but with less fancyness (no validation, no mixins). It will also wrap the body of render and render-state in sablono.core/html allowing you to write:

(defcomponent todo-item [todo]
  (render [_]
    [:li.todo {:class (:state todo)}
     [:.title (:title todo)]
     [:.text  (:text todo)]]))

Which will emit:

(defn todo-item [todo]
  (reify
    om/IDisplayName
    (display-name [_] "TodoItem")
    om/IRender
    (render [_]
      (html
       [:li.todo {:class (:state todo)}
        [:.title (:title todo)]
        [:.text  (:text todo)]]))))

You can find a short post on how this macro works and how it eliminates boilerplate on my Blog.

defcomponentmethod

Same as defcomponent but takes an extra dispatch-value arg and will emit a defmethod instead of defn.
