Overview

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

Examples:


# EnforcedStyle: with_first_parameter

# good

foo :bar,
    :baz

# bad

foo :bar,
  :baz

# EnforcedStyle: with_fixed_indentation

# good

foo :bar,
  :baz

# bad

foo :bar,
    :baz

'more than one line.'.freeze
FIXED_INDENT_MSG = 
'Use one level of indentation for parameters ' \
'following the first line of a multi-line method %s.'.freeze
