Elixir file manipulation

I used Mix.install to create an elixir script that reads all the files in a certain directory, manipulates those file names, and then creates a map using those file names.

Then I output that map to JSON data using Jason library.

Mix.install([{:jason, "~> 1.3"}])

Path.wildcard(
  Path.cwd!() <> "/loops/*"
)
|> Enum.reduce(%{}, fn "/home/aayushmau5/Downloads/experiments/loops/" <> remaining, acc ->
  loops_data = Map.get(acc, remaining, [])

  Map.put(acc, remaining, [
    %{
      "title" => String.split(remaining, " - ") |> Enum.at(0),
      "other" => String.split(remaining, " - ") |> Enum.at(-1) |> String.slice(0..-5),
    }
    | loops_data
  ])
end)
|> Jason.encode!()
|> IO.puts()

I like Path.wildcard\1 , and pattern matching to get remaining in Enum.reduce . Pretty neat!
