Perl::Critic::Policy::ControlStructures::ProhibitUnlessBUsersContributed Perl DocuPerl::Critic::Policy::ControlStructures::ProhibitUnlessBlocks(3) NAME
Perl::Critic::Policy::ControlStructures::ProhibitUnlessBlocks - Write "if(! $condition)" instead of "unless($condition)". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Conway discourages using "unless" because it leads to double-negatives that are hard to understand. Instead, reverse the logic and use "if". unless($condition) { do_something() } #not ok unless(! $no_flag) { do_something() } #really bad if( ! $condition) { do_something() } #ok This Policy only covers the block-form of "unless". For the postfix variety, see "ProhibitPostfixControls". CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO
