View Source Credo.Check.Readability.SingleFunctionToBlockPipe (Credo v1.7.2-rc.4)

This check has a base priority of 0 and works with any version of Elixir.

Explanation

A single pipe (|>) should not be used to pipe into blocks.

The code in this example ...

list
|> length()
|> case do
  0 -> :none
  1 -> :one
  _ -> :many
end

... should be refactored to look like this:

case length(list) do
  0 -> :none
  1 -> :one
  _ -> :many
end

If you want to disallow piping into blocks all together, use Credo.Check.Readability.BlockPipe.
