Let's say your configuration needs to supply one of a set of possible values (i.e. an enum). We can define a custom function to support this and pass it as the second argument to Dotenvy.env!/2

# runtime.exs
import Config
import Dotenvy

size_enum = fn
  "large" -> :large
  "small" -> :small
  _ ->
    raise Dotenvy.Error, message: "allowed size_enum values are large or small"
end

config :myapp, :some_bool, env!("SIZE", size_enum)
