Animal Generator

Often we need to create large amounts of fake data in order to test our applications. To simulate this experience, you’re going to build data for an animal simulator game.

Each animal will be represented with a map. Each map should have the keys name, animal_type, and age.

Use the following names, species, and age ranges to generate your animal data. You may alter this to suite your own creative preferences!

names = ["Clifford", "Zoboomafoo", "Leonardo"]
animal_types = ["dog", "lemur", "turtle"]
ages = 1..14

Your list of animals should include every permutation of names, species, and ages. There are 126 permutations in the data examples above.

Hint

Consider using names, animal_types, and ages as generators for a comprehension.

Example Solution

names = ["Clifford", "Zoboomafoo", "Leonardo"]
animal_types = ["dog", "lemur", "turtle"]
ages = 1..14

for name <- names, animal_type <- animal_types, age <- ages do
  %{name: name, animal_type: animal_type, age: age}
end 

Enter your solution below.

Mark As Completed

file_name = Path.basename(Regex.replace(~r/#.+/, __ENV__.file, ""), ".livemd")

save_name =
  case Path.basename(__DIR__) do
    "reading" -> "animal_generator_reading"
    "exercises" -> "animal_generator_exercise"
  end

progress_path = __DIR__ <> "/../progress.json"
existing_progress = File.read!(progress_path) |> Jason.decode!()

default = Map.get(existing_progress, save_name, false)

form =
  Kino.Control.form(
    [
      completed: input = Kino.Input.checkbox("Mark As Completed", default: default)
    ],
    report_changes: true
  )

Task.async(fn ->
  for %{data: %{completed: completed}} <- Kino.Control.stream(form) do
    File.write!(
      progress_path,
      Jason.encode!(Map.put(existing_progress, save_name, completed), pretty: true)
    )
  end
end)
