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

NAME
Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator - Write " <<'THE_END'; " instead of " <<'theEnd'; ". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
For legibility, HEREDOC terminators should be all UPPER CASE letters (and numbers), without any whitespace. Conway also recommends using a standard prefix like "END_" but this policy doesn't enforce that. print <<'the End'; #not ok Hello World the End print <<'THE_END'; #ok Hello World THE_END CONFIGURATION
