TreeMap 0.1

Elixir CI

A module to maintain a tree of the structure

  %TreeMap{ key: ..., value: ..., children: [%TreeMap{},...]}

and functions to traverse such a tree.

Examples

 root =
   TreeMap.new("1", "Root")
   |> TreeMap.add_child("1.1", "Sub One", [TreeMap.new("1.1.1", "SomeSubSub")])
   |> TreeMap.add_child("1.2", "Sub Two", [TreeMap.new("1.2.1", "Some other SubSub")])

 expected = ["1", "1.1", "1.1.1", "1.2", "1.2.1"]

 received =
   TreeMap.transduce(root, [], fn a, x -> a ++ [x] end, fn n, acc -> [n | acc] end)
   |> Enum.map(& &1.key)

 assert expected == received

Installation

Available in Hex, the package can be installed by adding tree_map to your list of dependencies in mix.exs:
