Manual Reference Pages - PERL::CRITIC::POLICY::REGULAREXPRESSIONS::REQUIREDOTMATCHANYTHING (3)
Perl::Critic::Policy::RegularExpressions::RequireDotMatchAnything - Always use the "/s" modifier with regular expressions.
This Policy is part of the core Perl::Critic
When asked what . in a regular expression means, most people will
say that it matches any character, which isnt true. Its actually
shorthand for [^\n]. Using the s modifier makes . act like
people expect it to.
my $match = m< foo.bar >xm; # not ok
my $match = m< foo.bar >xms; # ok
This Policy is not configurable except for the standard options.
Be cautious about slapping modifier flags onto existing regular
expressions, as they can drastically alter their meaning. See
<http://www.perlmonks.org/?node_id=484238> for an interesting
discussion on the effects of blindly modifying regular expression
