NAME
Perl::Critic::Policy::RegularExpressions::RequireLineBoundaryMatching - Always use the "/m" modifier with regular expressions.AFFILIATION
This Policy is part of the core Perl::Critic distribution.DESCRIPTION
Folks coming from a "sed" or "awk" background tend to assume that '$' and '^' match the beginning and end of the line, rather than then beginning and end 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
CONFIGURATION
This Policy is not configurable except for the standard options.NOTES
For common regular expressions like e-mail addresses, phone numbers, dates, etc., have a look at the Regexp::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.AUTHOR
