Class Method Details

.deep_merge(h, other) ⇒ Hash

RuboCop::SortedMethodsByCall::Util.deep_merge(hash, other) -> Hash

Merges two hashes without overwriting values that share the same key. When a key exists in both hashes, values are accumulated into an array (“buckets”). Scalars are wrapped to arrays automatically.

• Non-destructive: returns a new Hash; does not mutate hash.

• If other is not a Hash, the original hash is returned as-is.

Examples:

Accumulate values into buckets

base  = { main: :abc, class_T: :hi }
other = { class_T: :h1 }
RuboCop::SortedMethodsByCall::Util.deep_merge(base, other)
#=> { main: [:abc], class_T: [:hi, :h1] }

Parameters:

• h (Hash) —

  The base hash to merge from.

• other (Hash) —

  The hash to merge into hash.

Returns:

• (Hash) —

  A new hash with accumulated values per key.
