Public Instance Methods

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 } }

def deep_merge(other_hash, &block)
  dup.deep_merge!(other_hash, &block)
end

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

Same as deep_merge, but modifies self.

# File lib/kube_deploy_tools/deploy_config_file/deep_merge.rb, line 27
def deep_merge!(other_hash, &block)
  merge!(other_hash) do |key, this_val, other_val|
    if this_val.is_a?(Hash) && other_val.is_a?(Hash)
      this_val.deep_merge(other_val, &block)
    elsif block_given?
      block.call(key, this_val, other_val)
    else
      other_val
    end
  end
