NAME

Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write "q{}" instead of "''".

AFFILIATION

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

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.

    $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

CONFIGURATION

This Policy is not configurable except for the standard options.
