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.
