Style/WordArray

Safe autocorrect: Yes
✅ The autocorrect a cop does is safe (equivalent) by design.

Description

Overview

Checks for array literals made up of word-like
strings, that are not using the %w() syntax.

Alternatively, it can check for uses of the %w() syntax, in projects
which do not want to include that syntax.

NOTE: When using the percent style, %w() arrays containing a space
will be registered as offenses.

Configuration option: MinSize
If set, arrays with fewer elements than this value will not trigger the
cop. For example, a MinSize of 3 will not enforce a style on an
array of 2 or fewer elements.

Examples

EnforcedStyle: percent (default)

# good
%w[foo bar baz]

# bad
['foo', 'bar', 'baz']

# bad (contains spaces)
%w[foo\ bar baz\ quux]

# bad
[
  ['one', 'One'],
  ['two', 'Two']
]

# good
[
  %w[one One],
  %w[two Two]
]

# good (2d array containing spaces)
[
  ['one', 'One'],
  ['two', 'Two'],
  ['forty two', 'Forty Two']
]

EnforcedStyle: brackets

# good
['foo', 'bar', 'baz']

# bad
%w[foo bar baz]

# good (contains spaces)
['foo bar', 'baz quux']

# good
[
  ['one', 'One'],
  ['two', 'Two']
]

# bad
[
  %w[one One],
  %w[two Two]
]
