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; # okCONFIGURATION
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.
