Perl::Critic::Policy::ControlStructures::ProhibitUntilBlUser(Contributed Perl DocPerl::Critic::Policy::ControlStructures::ProhibitUntilBlocks(3pm)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.

Perl::Critic::Policy::ControlStructures::ProhibitDeepNests - Don't write deeply nested loops and conditionals.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Deeply nested code is often hard to understand and may be a sign that it needs to be refactored. There are several good books on how to
refactor code. I like Martin Fowler's "Refactoring: Improving The Design of Existing Code".
CONFIGURATION
The maximum number of nested control structures can be configured via a value for "max_nests" in a .perlcriticrc file. Each for-loop, if-
else, while, and until block is counted as one nest. Postfix forms of these constructs are not counted. The default maximum is 5.
Customization in a .perlcriticrc file looks like this:
[ControlStructures::ProhibitDeepNests]
max_nests = 3
