Overview

Here we check if the elements of a multi-line array literal are aligned.

Examples:

EnforcedStyle: with_first_element (default)

# good

array = [1, 2, 3,
         4, 5, 6]
array = ['run',
         'forrest',
         'run']

# bad

array = [1, 2, 3,
  4, 5, 6]
array = ['run',
     'forrest',
     'run']

EnforcedStyle: with_fixed_indentation

# good

array = [1, 2, 3,
  4, 5, 6]

# bad

array = [1, 2, 3,
         4, 5, 6]

Constant Summary collapse

ALIGN_ELEMENTS_MSG = 
'Align the elements of an array literal ' \
'if they span more than one line.'
FIXED_INDENT_MSG = 
'Use one level of indentation for elements ' \
'following the first line of a multi-line array.'
