I need to do the following: Read data from file Parse custom syntax 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 |> Strea…

You’ll have to modify part of the code to read the data from a file but otherwise it works. Key insight: use Enum.reduce to accumulate values into a single return value, instead of making a one-keyed map for each parsed line. defmodule Parse1 do def data(), do: ~S""" jhb team names:hawks,mauler…

Can you post some example source data (and possibly the source of create_index_name)? Also, please format your code blocks with triple backticks, right now it’s almost unreadable.

[image] dimitarvp: triple backticks Thx, here goes: 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(&M…

Hi @anthonyl ! Welcome! I saw @dimitarvp answered your question already by asking a little bit more about your problem (good technique). Even though you solved the problem a different way, I thought I’d focus on what you asked first: You had an input in a certain shape (list of maps), you wanted an …

In this case, I wouldn’t even bother with the Stream.map calls. The extra indirection is slowing you down and adding complexity for no real benefit. Thanks to @dimitarvp 's nice sample code, I took it and modified a bit to be more direct. defmodule Parse2 do def data(), do: ~S""" jhb team names…
