Perl::Critic::PPerl::CUsercContributedoPerllDocumentationrohibitUntilBlocks(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.
