handling recursion - any Enumerable elements (except String) is being extended with the module, and then symbolized
# File lib/deep_symbolize.rb, line 57 def _recurse_(value, &block) if value.is_a?(Enumerable) && !value.is_a?(String) # support for a use case without extended core Hash unless value.class.include?(DeepSymbolizable) value.extend DeepSymbolizable end value = value.deep_symbolize(&block) end value end

walking over arrays and symbolizing all nested elements
# File lib/deep_symbolize.rb, line 51 def array(ary, &block) ary.map { |v| _recurse_(v, &block) } end
hash(hash) { |key| ... }

the primary method - symbolizes keys of the given hash, preprocessing them with a block if one was given, and recursively going into all nested enumerables
# File lib/deep_symbolize.rb, line 31 def hash(hash, &block) hash.each_with_object({}) do |(key, value), result| # Recursively deep-symbolize subhashes value = _recurse_(value, &block) # Pre-process the key with a block if it was given key = yield key if block_given? # Symbolize the key string if it responds to to_sym sym_key = begin key.to_sym rescue StandardError key end # write it back into the result and return the updated hash result[sym_key] = value end end
