NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitSpecialLiteralHeredocTerminator - Don't write " print <<'__END__' ".

AFFILIATION

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

DESCRIPTION

       Using one of Perl's special literals as a HEREDOC terminator could be confusing to tools that try to parse perl.

	   print <<'__END__';		#not ok
	   Hello world
	   __END__

	   print <<'__END_OF_WORLD__';	#ok
	   Goodbye world!
	   __END_OF_WORLD__

       The special literals that this policy prohibits are:

       __END__
       __DATA__
       __PACKAGE__
       __FILE__
       __LINE__

CONFIGURATION

       This Policy is not configurable except for the standard options.

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.
