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 "[^\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

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.
