NAME

       Perl::Critic::Policy::RegularExpressions::RequireDotMatchAnything - Always use the "/s" modifier with regular expressions.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       When asked what "." in a regular expression means, most people will say that it matches any character, which isn't true.  It's actually
       shorthand for "[^
]".  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

CONFIGURATION

       This Policy is not configurable except for the standard options.

NOTES

       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 flags.
