# File 'lib/doing/util.rb', line 58 def deep_merge_hashes(master_hash, other_hash) deep_merge_hashes!(master_hash.dup, other_hash) end |
#deep_merge_hashes!(target, overwrite) ⇒ Object
Merges a master hash with another hash, recursively.
master_hash - the "parent" hash whose values will be overridden other_hash - the other hash whose values will be persisted after the merge
This code was lovingly stolen from some random gem: http://gemjack.com/gems/tartan-0.1.1/classes/Hash.html
Thanks to whoever made it.
