xenial (3) Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators.3pm.gz

Provided by: libperl-critic-perl_1.126-1_all bug

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.
