Overview

Here we check if the parameters on a multi-line method call or definition are aligned.

Examples:

EnforcedStyle: with_first_parameter (default)

# good

foo :bar,
    :baz

# bad

foo :bar,
  :baz

EnforcedStyle: with_fixed_indentation

# good

foo :bar,
  :baz

# bad

foo :bar,
    :baz
