Overview

Here we check if the arguments on a multi-line method definition are aligned.

Examples:

EnforcedStyle: with_first_argument (default)

# good

foo :bar,
    :baz

foo(
  :bar,
  :baz
)

# bad

foo :bar,
  :baz

foo(
  :bar,
    :baz
)

EnforcedStyle: with_fixed_indentation

# good

foo :bar,
  :baz

# bad

foo :bar,
    :baz

Constant Summary collapse

ALIGN_PARAMS_MSG = 
'Align the arguments of a method call if ' \
'they span more than one line.'
FIXED_INDENT_MSG = 
'Use one level of indentation for arguments ' \
'following the first line of a multi-line method call.'
