perl::critic::policy::regularexpressions::prohibitunusualdelimit

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.
