Pipe to Complex Map

Questions & Help Questions

I need to do the following:

  1. Read data from file
  2. Parse custom syntax
  3. Write result to a map

I have the following code:

File.stream!(load_path,[:read, :utf8]) #Read File
    |> Stream.map(&String.trim(&1)) #Trim Each Element
    |> Stream.map(&String.downcase(&1)) #Convert to Lowercase
    |> Stream.map(&String.split(&1, [":", ","])) #Split at Delimiters
    |> Stream.map(&Map.put(%{}, create_index_name(hd(&1)), tl(&1))) #Write to Map
    |> Enum.map(&IO.inspect(&1)) #Enumerate through stream

Which outputs a list with map entries in it like so:

[
  %{":jhb_team_names" => ["hawks", "maulers", "eagles", wolves"]},
  %{":dbn_team_names" => ["sqeaks", "bunfighters"]}
]

I need it to output something like:

  %{":jhb_team_names" => ["hawks", "maulers", "eagles", wolves"],
  	:dbn_team_names" => ["sqeaks", "bunfighters"]}

i.e. a single map, which can be simply accessed with a key => value lookup.

This should be simple to do, but my newness to Elixir is stumping me.

Any suggestions on how this can be accomplished?
