Convenience functions

[tatut]

Currently combining style information with other attributes seems quite verbose, like:

[:a (merge (stylefy/use-style some-style-ns/link-style)
                  {:on-click #(...)})
  "click me"]

A more convenient shorthand would be nice (though I don't yet know what would be the best).

Perhaps defining a pre-styled element, like:

;; define pre-styled constructor
(def my-link (stylefy/with-style :a some-style-ns/link-style))

(defn my-component []
 ;; use it like any reagent component
  [my-link {:on-click #(...)} "click me"])

This can obviously be done separately without adding it to stylefy, but I think a recommended way would be nice.

Neat, this idea is worth testing!

I think this problem got a bit less painful after use-style started accepting HTML attributes as the second parameter.

Agreed, and further convenience wrappers can be provided by wrapping the component in an HOC that does a lot of the hard work for you, e.g.

[with-style [:a {...} "click me"]]

(defn- normalise
  [attrs-and-children]
  (if (and (not (second attrs-and-children))
           (sequential? (first attrs-and-children))
           (coll? (ffirst attrs-and-children)))
    (first attrs-and-children)
    attrs-and-children))

;; Merge new attrs map into Attrs & Children sequence
(defn merge-attrs
  [default-attrs [attrs & children :as attrs-and-children]]
  (if (map? attrs)
    (cons (merge default-attrs attrs) children)
    (cons default-attrs attrs-and-children)))

;; Gernerate Hiccup with Stylefy styles and variadic args
(defn with-style
  [style-map style [element & attrs-and-children]]
  (let [style (get (get style-map @theme) style)
        [attrs & children] (->> (normalise attrs-and-children)
                                (merge-attrs {}))
        attrs' (or (use-style style attrs) attrs)]
    (into [element] (cons attrs' children))))
