From: "zzak (Zachary Scott)" Date: 2013-04-11T08:03:51+09:00 Subject: [ruby-core:54160] [ruby-trunk - Feature #8246][Open] Hash#traverse Issue #8246 has been reported by zzak (Zachary Scott). ---------------------------------------- Feature #8246: Hash#traverse https://bugs.ruby-lang.org/issues/8246 Author: zzak (Zachary Scott) Status: Open Priority: Normal Assignee: Category: core Target version: =begin From (()) Traverses the given levels of a hash and returns the value associated with the last key provided. Allows for concise access for deeply nested hashes - often encountered with dealing with external restful apis. (({hash = { level1: { level2: { level3: 3 } } }})) (({hash.traverse :level1, :level2, :level3 #=> 3})) Also supports a default value block if the value is nil or the key is not found. (({hash.traverse(:level1, :level2, :non_existent_key) { 5 } #=> 5})) =end -- http://bugs.ruby-lang.org/
