Access a nested Ruby Hash using Java-style properties as keys.
require "property_hash"
require "pp"
h = {
:a => {
:b => 1,
:c => { :d => "DEEEE" },
:x => 888,
:y => [9999]
},
:b => {
:zeee => 888
}
}
ph = PropertyHash.new(h)
p ph["a.c.d"] # DEEEE
p ph["b.zeee"] # 888
ph["a.c.x"] = "X"
pp ph.keys # ["a.b", "a.c.d", "a.x", "a.y", "b.zeee", "a.c.x"]
pp ph.values # [1, "DEEEE", 888, [9999], 888, "X"]
ph.each { |k, v| p k }
pp ph.to_h # h but with :a => { :c => { :x => "X" } }Add this line to your application's Gemfile:
