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.

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitNoisyQuotes - Use "q{}" or "qq{}" instead of quotes for awkward-looking strings.

AFFILIATION

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

DESCRIPTION

       Don't use quotes for one or two-character strings of non-alphanumeric characters (i.e. noise).  These tend to be hard to read.  For
       legibility, use "q{}" or a named value.	However, braces, parentheses, and brackets tend do to look better in quotes, so those are allowed.

	   $str = join ',', @list;     #not ok
	   $str = join ",", @list;     #not ok
	   $str = join q{,}, @list;    #better

	   $COMMA = q{,};
	   $str = join $COMMA, @list;  #best

	   $lbrace = '(';	   #ok
	   $rbrace = ')';	   #ok
	   print '(', @list, ')';  #ok

CONFIGURATION

       This Policy is not configurable except for the standard options.
