How can I tell PhpStorm (using version 8.0.3) to keep the following array as is when clicking Cmd+Alt+L to reformat my code:
$array = [ 'short' => 1, // I want this... 'veryVeryVeryIncrediblyLong' => 123456789, ]; Instead of doing this:
$array = [ 'short' => 1, // Not this... 'veryVeryVeryIncrediblyLong' => 123456789, ];
