class Hash - phonejack-1.2.0 Documentation

deep_deep_merge(other_hash, &block) click to toggle source

Returns a new hash with self and other_hash merged recursively.

h1 = { a: true, b: { c: [1, 2, 3] } }
h2 = { a: false, b: { x: [3, 4, 5] } }

h1.deep_merge(h2) # => { a: false, b: { c: [1, 2, 3], x: [3, 4, 5] } }

Like with Hash#merge in the standard library, a block can be provided to merge values:

h1 = { a: 100, b: 200, c: { c1: 100 } }
h2 = { b: 250, c: { c1: 200 } }
h1.deep_merge(h2) { |key, this_val, other_val| this_val + other_val }
# => { a: 100, b: 450, c: { c1: 300 } }

deep_deep_merge!(other_hash, &block) click to toggle source

Same as deep_merge, but modifies self.

# File lib/utilities/hash.rb, line 21
def deep_deep_merge!(other_hash, &block)
  other_hash.each_pair do |current_key, other_value|
    this_value = self[current_key]

    self[current_key] = if this_value.is_a?(Hash) && other_value.is_a?(Hash)
      this_value.deep_deep_merge(other_value, &block)
    else
      if block_given? && key?(current_key)
        block.call(current_key, this_value, other_value)
      else
        other_value
      end
    end
  end

  self
end
