I thought of practicing, but then I just wound up doing a lot of thinking.
Then it clicked 😬
defmodule Words do
def count("" <> string), do: parse(string) |> Enum.reduce(%{}, &count/2)
defp count("", map), do: map
defp count("" <> word, map) do
word |> String.replace("_", "-")
|> increment(map)
end
defp increment(word, map), do: put_in(map[word], (map[word] || 0) + 1)
defp parse(string), do: string |> String.downcase |> String.replace("-",
"&hyph;") |> String.replace("_", "-") |> String.replace("&hyph;", "_") |>
String.split(~r/\W/u)
end
It's just a challenge to think of meaningful names sometimes. Breaking
function/method bodies into smaller discrete blocks of work is obviously a
fundament to making code more readable, but it takes discipline and,
sometimes, a thesaurus
Thank you for entertaining this zombie discussion once more 😶
