Smush

Smush is a simple gem that converts a hash into a flat array of key-value pairs. You can also unsmush the result back into a hash. Note: if an integer key is encountered, Smush will always assume the target object is an Array.

Unsmushed

{
  name: 'John Doe',
  chores: ['Wash dishes', 'Pay rent']
}

Smushed

[
  {
    key: [:name],
    value: 'John Doe'
  },
  {
    key: [:chores, 0],
    value: 'Wash dishes'
  },
  {
    key: [:chores, 1],
    value: 'Pay rent'
  }
]

Smush does not check your inputs for consistency, e.g. check that your smushed hash doesn't have duplicate keys, or that you aren't skipping indices in your arrays.
