View Source Credo.Check.Readability.SinglePipe (Credo v1.7.10)

Basics

This check is disabled by default.

Learn how to enable it via .credo.exs.

This check is tagged :controversial

This means that this check is more opinionated than others and not for everyone's taste.

This check has a base priority of high and works with any version of Elixir.

Explanation

Pipes (|>) should only be used when piping data through multiple calls.

So while this is fine:

list
|> Enum.take(5)
|> Enum.shuffle
|> evaluate()

The code in this example ...

list
|> evaluate()

... should be refactored to look like this:

evaluate(list)

Using a single |> to invoke functions makes the code harder to read. Instead, write a function call when a pipeline is only one function long.

Like all Readability issues, this one is not a technical concern. But you can improve the odds of others reading and liking your code by making it easier to follow.
