Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write q{} instead of ''.
q{}
''
This Policy is part of the core Perl::Critic distribution.
Don't use quotes for an empty string or any string that is pure whitespace. Instead, use q{} to improve legibility. Better still, created named values like this. Use the x operator to repeat characters.
x
$message = ''; #not ok $message = ""; #not ok $message = " "; #not ok $message = q{}; #better $message = q{ } #better $EMPTY = q{}; $message = $EMPTY; #best $SPACE = q{ }; $message = $SPACE x 5; #best
This Policy is not configurable except for the standard options.
