Dolly
Utilities for cloning vars in Clojure and Clojurescript.
Installation
{io.github.jerems/dolly {:git/tag "v29", :git/sha "cfefa49133"}}Usage
(defn foo
"Some foo doc"
[])
;; We can clone foo in the same ns or not
(def-clone bar foo)
;; The docstring (and other var metadata) is cloned
(clojure.repl/doc foo)
;=> "Some foo doc"
;; We can clone macros
(defmacro baz
"Some doc for baz."
[])
;; And change some metadata for the clone.
(def-clone ^{:doc "Some other doc"}cloned-baz baz)
(clojure.repl/doc cloned-baz)
;=> "Some other doc"Inspirations
This project is inspired by https://github.com/aleph-io/potemkin import var system.
However dolly's def-clone doesn't link aliased vars to propagate change when the original is redefined.
I don't think that's possible in Clojurescript and this projects aims to work with it.
