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