perl::critic::policy::regularexpressions::requiredotmatchanythin(3pm) [debian man page]

Perl::Critic::Policy::RegularExpressions::RequireDotMatcUsertContributed PerPerl::Critic::Policy::RegularExpressions::RequireDotMatchAnything(3pm)

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 "[^
]".  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.

Perl::Critic::Policy::RegularExpressions::ProhibitUnusuaUseriContributed PerPerl::Critic::Policy::RegularExpressions::ProhibitUnusualDelimiters(3)

NAME

       Perl::Critic::Policy::RegularExpressions::ProhibitUnusualDelimiters - Use only "//" or "{}" to delimit regexps.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Perl lets you delimit regular expressions with almost any character, but most choices are illegible.  Compare these equivalent expressions:

	 s/foo/bar/;   # good
	 s{foo}{bar};  # good
	 s#foo#bar#;   # bad
	 s;foo;bar;;   # worse
	 s||||||;   # eye-gouging bad

CONFIGURATION

       There is one option for this policy, "allow_all_brackets".  If this is true, then, in addition to allowing "//" and "{}", the other matched
       pairs of "()", "[]", and "<>" are allowed.

CREDITS

       Initial development of this policy was supported by a grant from the Perl Foundation.
