Perl::Critic::Policy::RegularExpressions::RequireDotMatchAnything(3)
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.
