|
* @since 0.11.0 - The WordPress specific additional checks have now been split off

* from the `WordPress.Arrays.ArrayDeclaration` sniff into this sniff.
|
|
* - Added sniffing & fixing for associative arrays.
|
|
* @since 0.12.0 Decoupled this sniff from the upstream sniff completely.
|
|
* This sniff now extends the WordPressCS native `Sniff` class instead.
|
|
* @since 0.13.0 Added the last remaining checks from the `WordPress.Arrays.ArrayDeclaration`
|
|
* sniff which were not covered elsewhere.
|
|
* The `WordPress.Arrays.ArrayDeclaration` sniff has now been deprecated.
|
|
* @since 0.13.0 Class name changed: this class is now namespaced.
|
|
* @since 0.14.0 Single item associative arrays are now by default exempt from the
|
|
* "must be multi-line" rule. This behaviour can be changed using the
|
|
* `allow_single_item_single_line_associative_arrays` property.
|
|
* @since 3.0.0 Removed various whitespace related checks and fixers in favour of the PHPCSExtra
|
|
* `NormalizedArrays.Arrays.ArrayBraceSpacing` sniff.
