Method: Hash#recursively

Defined in:

lib/core/facets/hash/recursively.rb

#recursively(*types, &block) ⇒ Object

Apply a block to a hash, and recursively apply that block to each sub-hash:

h = {:a=>1, :b=>{:x=>1, :y=>2}}
h.recursively.map{ |k,v| [k.to_s, v] }
#=> [["a", 1], ["b", [["y", 2], ["x", 1]]]]

The recursive iteration can be treated separately from the non-recursive iteration by passing a block to the #recursive method:

h = {:a=>1, :b=>{:x=>1, :y=>2}}
h.recursively{ |k,v| [k.to_s, v] }.map{ |k,v| [k.to_s, v.to_s] }
#=> [["a", "1"], ["b", [["y", "2"], ["x", "1"]]]]
