View Source Credo.Check.Readability.NestedFunctionCalls (Credo v1.6.7)
This check has a base priority of 0 and works with any version of Elixir.
Explanation
A function call should not be nested inside another function call.
So while this is fine:
Enum.shuffle([1,2,3])The code in this example ...
Enum.shuffle(Enum.uniq([1,2,3,3]))... should be refactored to look like this:
[1,2,3,3]
|> Enum.uniq()
|> Enum.shuffle()Nested function calls make the code harder to read. Instead, break the function calls out into a pipeline.
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.
Check-Specific Parameters

:min_pipeline_length
Set a minimum pipeline length
