Credo.Check.Refactor.FunctionArity (Credo v1.5.0) View Source

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

Explanation

A function can take as many parameters as needed, but even in a functional language there can be too many parameters.

Can optionally ignore private functions (check configuration options).

Configuration parameters

Use the following parameters to configure this check:

• max_arity: The maximum number of parameters which a function should take.

  Defaults to 8

• ignore_defp: Set to true to ignore private functions.

  Defaults to false

Like with all checks, general params can be applied.

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