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.
