replace-last

[expez]

Sometimes you want to replace the last occurrence.

@expez not sure about clojurescript, but for clojure you can use the .lastIndexOf method.

(defn replace-last [^String s ^String match ^String replacement]
  (let [last-index (.lastIndexOf s match)]
    (if (== last-index -1)
      s
      (-> (.substring s 0 last-index)
          java.lang.StringBuilder.
          (.append replacement)
          (.append (.substring s (+ last-index (.length match))))
          .toString))))

@beoliver Yeah, but it's always the cljs part that's tricky :p

Get on that and cut a new release. Been a while! :)

@expez javascript has lastIndexOf and substring so it should be fairly straightforward.
