A library to work with tagged tuples.
Provides functions to work with chains of tags for nested tuples.
Some of the supported operations are: add/remove tag chain to a core value, converting a tuple to list or to map and back. The latter one is useful for converting tuples to/from JSON representation.
iex> use TaggedTuple
...> core_value = 12
...> :tag --- core_value
{:tag, 12}
...> tagged_tuple = :a --- :tag --- :chain --- core_value
{:a, {:tag, {:chain, 12}}}
...> match?(:a --- :tag --- _tail, tagged_tuple)
true
iex> {chain, value} = TaggedTuple.split({:a, {:tag, {:chain, 2}}})
...> chain == {:a, {:tag, :chain}}
...> value == 2
iex> TaggedTuple.tag(2, {:a, {:tag, :chain}})
{:a, {:tag, {:chain, 2}}}
iex> TaggedTuple.to_map({:a, {:tag, {:chain, 2}}})
%{a: %{tag: %{chain: 2}}}
iex> TaggedTuple.from_map(%{a: %{tag: %{chain: 2}}})
{:a, {:tag, {:chain, 2}}}
