HashArray

A HashArray, for all intents and purposes, acts like an array. However, the common stuff are overloaded to work with hashes.

Basic usage

Creating

You can create a HashArray by passing it an array.

dict = HashArray.new([
  { :good_morning => "Bonjour" },
  { :goodbye      => "Au revoir" },
  { :good_evening => "Bon nuit" }
])

Converting

You may also use it like so:

letters = [ { :a => "Aye"}, { :b => "Bee" } ].to_hash_array

Iterating

Now you can use the typical enumerator functions:

dict.each do |(key, value)|
  puts "#key is #value"
end

#=> :good_morning is "Bonjour"
#   :goodbye is "Au revoir"
#   :good_evening is "Bon nuit"
