Elixir: Macros hygiene

🚧 In development

The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.

In my environment the code works, but not here 🤨

My code is different from the teacher's one 🤔

I've read the lessons but nothing is clear 🙄

Прочитал урок — ничего не понятно 🙄

Found a bug? Have something to add? Pull requests are welcome!

Your exercise will be checked with these tests:

defmodule Test do
  use ExUnit.Case

  import ExUnit.CaptureIO

  defmodule Exercise do
    require Solution

    def run_fn(function) do
      Solution.with_logging do
        function
      end
    end
  end

  test "with_logging work" do
    assert capture_io(fn -> Exercise.run_fn(fn -> 1 + 5 end) end) ==
             "Started execution...\nExecution result is: 6\n"

    assert capture_io(fn -> Exercise.run_fn(fn -> %{hello: :world} end) end) ==
             "Started execution...\nExecution result is: %{hello: :world}\n"

    assert capture_io(fn ->
             Exercise.run_fn(fn -> "some string" end)
           end) == "Started execution...\nExecution result is: \"some string\"\n"
  end
end
