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.
