Credo.Check.Readability.ParenthesesOnZeroArityDefs (Credo v1.5.0) View Source

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


Either use parentheses or not when defining a function with no arguments.

By default, this check enforces no parentheses, so zero-arity function and macro definitions should look like this:

def summer? do
  # ...

If the :parens param is set to true for this check, then the check enforces zero-arity function and macro definitions to have parens:

def summer?() do
  # ...

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.

Configuration parameters

There are no specific parameters for this check.

Like with all checks, general params can be applied.

Parameters can be configured via the .credo.exs config file.
