The hierarchy library is an opinionated Clojure library primarily designed to enhance the built-in hierarchy functions, it removes the constraints that the hierarchy relationship's parent must be a namespace-qualified symbol or keyword and or that child must be either a namespace-qualified symbol or keyword or a class.
Here's are a couple of examples.
(ns user
(:require [hierarchy.core :as h]))
;;; using with a hierarchy
(-> (make-hierarchy)
(h/derive+ :bar [:that "thing"])
(h/derive+ :foo :bar)
(isa? :foo [:that "thing"])) ;; => true
;;; using global hierarchy via `derive+` and `underive+` directly
(h/derive+ :bar [:that "thing"])
(h/derive+ :foo :bar)
(isa? :foo [:that "thing"]) ;; => true
;;; using global hierarchy with redef'd `derive` and `underive` using `bound`
(h/bound ;;; this allows more precise use where needed
(derive :bar [:that "thing"])
(derive :foo :bar)
(isa? :foo [:that "thing"])) ;; => true
;;; using global hierarchy with altered `derive` and `underive` vars using `activate!`
(h/activate!) ;;; your application can activate global bindings
(derive :bar [:that "thing"])
(derive :foo :bar)
(isa? :foo [:that "thing"]) ;; => true
(h/deactivate!) ;;; this exists mainly for testingSee the existing tests for more examples.
hierarchy is built, tested, and deployed using Clojure Tools Deps.
GNU Make is used to simplify invocation of some commands.
hierarchy releases for this project are on Clojars. Simply add the following to your project:
