어떻게 세었어?

매우 유용한 페이지

이런 느낌

:code.all_loaded()
|> Enum.filter(fn {mod, _} -> "#{mod}" =~ ~r{^[A-Z]} end)
|> Enum.map(fn {mod, _} -> mod end)
|> Enum.reduce(%{}, fn mod, acc -> 
  Map.put(acc, mod, mod.__info__(:functions))
end)

결과

  Module => [
    __get_attribute__: 3,
    __put_attribute__: 4,

  Inspect => [__protocol__: 1, impl_for: 1, impl_for!: 1, inspect: 2],
  Access => [
    all: 0,
    at: 1,

수를 세자.

:code.all_loaded()
|> Enum.filter(fn {mod, _} -> "#{mod}" =~ ~r{^[A-Z]} end)
|> Enum.map(fn {mod, _} -> mod end)
|> Enum.reduce(%{}, fn mod, acc ->
  Map.put(acc, mod, mod.__info__(:functions))
end)
|> Enum.reduce(0, fn {_, funs}, acc -> acc + Enum.count(funs) end)

Wrapping Up

Enjoy :code.all_loaded/0 !!!
