Perl::Critic::Policy::ControlStructures::ProhibitUnlessBUsersContributed Perl DoPerl::Critic::Policy::ControlStructures::ProhibitUnlessBlocks(3pm)
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
