Elixir file manipulation

Manipulating arbitrary number of files present in a directory using Elixir

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!
