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.
