Perl::Critic::Policy::RegularExpressions::ProhibitUnusualDelimiters

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.
