Perl::Critic::Policy::RegularExpressions::RequireBracesFUserlContributed PPerl::Critic::Policy::RegularExpressions::RequireBracesForMultiline(3pm)

NAME

       Perl::Critic::Policy::RegularExpressions::RequireBracesForMultiline - Use "{" and "}" to delimit multi-line regexps.

AFFILIATION

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

DESCRIPTION

       Long regular expressions are hard to read.  A good practice is to use the "x" modifier and break the regex into multiple lines with
       comments explaining the parts.  But, with the usual "//" delimiters, the beginning and end can be hard to match, especially in a "s///"
       regexp.	Instead, try using "{}" characters to delimit your expressions.

       Compare these:

	   s/
	      <a s+ href="([^"]+)">
	       (.*?)
	      </a>
	    /link=$1, text=$2/xms;

       vs.

	   s{
	      <a s+ href="([^"]+)">
	       (.*?)
	      </a>
	    }
	    {link=$1, text=$2}xms;

       Is that an improvement?	Marginally, but yes.  The curly braces lead the eye better.

CONFIGURATION

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

CREDITS

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

Perl::Critic::Policy::RegularExpressions::ProhibitEnumerUserCContributed PerPerl::Critic::Policy::RegularExpressions::ProhibitEnumeratedClasses(3)

NAME

       Perl::Critic::Policy::RegularExpressions::ProhibitEnumeratedClasses - Use named character classes instead of explicit character lists.

AFFILIATION

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

DESCRIPTION

       This policy is not for everyone!  If you are working in pure ASCII, then disable it now or you may see some false violations.

       On the other hand many of us are working in a multilingual world with an extended character set, probably Unicode.  In that world, patterns
       like "m/[A-Z]/" can be a source of bugs when you really meant "m/p{IsUpper}/".	This policy catches a selection of possible incorrect
       character class usage.

       Specifically, the patterns are:

       "[	
f ]" vs. "s"

       "[	
 ]" vs. "s"   (because many people forget "f")

       "[A-Za-z0-9_]" vs. "w"

       "[A-Za-z]" vs. "p{IsAlphabetic}"

       "[A-Z]" vs. "p{IsUpper}"

       "[a-z]" vs. "p{IsLower}"

       "[0-9]" vs. "d"

       "[^w]" vs. "W"

       "[^s]" vs. "S"

CONFIGURATION

       This Policy is not configurable except for the standard options.
