Hello, Elixir gang. I’m starting to get the hang of Elixir, which has been challenging since I’m not coming from Ruby. I have been struggling to find a solution for a particular problem. I need to generate a list of strings which increments over the alphabet. So
["A", "B", "C"] is a very basic example.
When the end of the alphabet is reached, I want the result to look like this:
[..."X", "Y", "Z", "AA", "BB"...]. The goal is to create a function like this:
I tried using the Alphabetify package, but it was pretty slow, and didn’t quite give me the results I needed. String.duplicate got me almost there, but I still wasn’t getting the right output.
Does anyone have an idea or package suggestion for this problem? I’ve hit a wall on this one.
Where I’m at
letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" |> String.split("", trim: true) def generate_list(first_letter, count) when is_binary(first_letter) when is_integer(count) do # letters # |> Stream.cycle # |> Stream.take(count) starting_index = letters |> Enum.find_index(fn x -> x == first_letter end) # 0..count # |> Enum.map(fn x -> end) end
