perl::critic::policy::valuesandexpressions::prohibitmixedboolean
Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixeUserlContributPerl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators(3)
NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators - Write " !$foo && $bar || $baz " instead of " not $foo && $bar
or $baz".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway advises against combining the low-precedence booleans ( "and or not" ) with the high-precedence boolean operators ( "&& || !" ) in
the same expression. Unless you fully understand the differences between the high and low-precedence operators, it is easy to misinterpret
expressions that use both. And even if you do understand them, it is not always clear if the author actually intended it.
next if not $foo || $bar; #not ok
next if !$foo || $bar; #ok
next if !( $foo || $bar ); #ok
CONFIGURATION
This Policy is not configurable except for the standard options.
