NAME

Perl::Critic::Policy::RegularExpressions::RequireLineBoundaryMatching

DESCRIPTION

Folks coming from a "sed" or "awk" background tend to assume that '$' and '^' match the beginning and and of the line, rather than then beginning and ed of the string. Adding the '/m' flag to your regex makes it behave as most people expect it should. 
   my $match = m{ ^ $pattern $ }x;  #not ok
   my $match = m{ ^ $pattern $ }xm; #ok

NOTES

For common regular expressions like e-mail addresses, phone numbers, dates, etc., have a look at the Regex::Common module. Also, be cautions 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.
