Elixir IO.inspect to debug pipelines

While writing multiple pipelines, you may want to debug the intermediate values. Just insert |> IO.inspect between your pipelines.

e.g. in the expression below:

1
2
3
4
:crypto.strong_rand_bytes(32)
  |> :base64.encode_to_string
  |> :base64.decode
  |> :base64.encode

If we want to check intermediate values we just need to add a |> IO.inspect

1
2
3
4
5
6
7
8
:crypto.strong_rand_bytes(32)
  |> IO.inspect
  |> :base64.encode_to_string
  |> IO.inspect
  |> :base64.decode
  |> IO.inspect
  |> :base64.encode
  |> IO.inspect

This will print all the intermediate values to the STDOUT. IO.inspect is a function which prints the input and returns it.
