DOUBLEDOT

Nicknames and package shorthands that might actually work.

Born of half a week of having to deal with multiple Java classes with the same package but a different name, and of half an evening of spare time (the 80% of it, that is).

Never worry about that again! With only a bit of flagrant violation of Clojure's reserved symbols rules you too can experience the joy of nicknames for classes and shorthands for packages that work (almost) everywhere! If you aren't feeling adventurous or you just want your subforms to still make sense in isolation, there also is a reader macro to apply to single symbols that sadly makes the name of this library meaningless.

By default, the reader-macros #+! and #-! are bound respectively to read-shortened and read-shortened-sym, but a readerless version is also available that lets you define your own instead.

Alpha.

USAGE EXAMPLE

(shorthands '{j.u java.util clj clojure.lang})
;; This is a bad example!
;; I implemented the feature because perhaps someone has a better idea than me on how to use it,
;; but in my time using this I've never had a case where I reached for this.
;; That being said, Clojure well and truly converted me to the religion of the Namespace
;; and I hardly ever `refer` a function nowadays, so maybe it's just me.
(nichnames {'DomNode org.w3c.dom.Node}) 

;; recursive reader (interacts safely with itself)
#+!
(defn foo
  [self]
  (condp instance? self
    ..clj.IPersistentMap :pmap
    #+! ..j.u.concurrent.ConcurrentHashMap :concurrent-hash-map
    ..j.u.Map :map
    ..DomNode :dom-node!?))

;; single symbol reader with no `..` requirement (interacts safely with recursive reader)
;; also, note how `#+!` also works on metadata.
(def coll->array-list #+! ^[..j.u.Collection] #-! j.u.ArrayList/new)
