NAME
Perl::Critic::Policy::RegularExpressions::ProhibitCaptureWithoutTest - Capture variable used outside conditional.AFFILIATION
This Policy is part of the core Perl::Critic distribution.DESCRIPTION
If a regexp match fails, then any capture variables ($1, $2, ...) will be undefined. Therefore it's important to check the return value of a match before using those variables.This policy checks that capture variables are inside a conditional and do not follow an regexps.
This policy does not check whether that conditional is actually testing a regexp result, nor does it check whether a regexp actually has a capture in it. Those checks are too hard.
CONFIGURATION
This Policy is not configurable except for the standard options.AUTHOR
