NAME

Perl::Critic::Policy::RegularExpressions::ProhibitSingleCharAlternation - Use [abc] instead of a|b|c.

AFFILIATION

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

DESCRIPTION

Character classes (like [abc]) are significantly faster than single character alternations (like (?:a|b|c)). This policy complains if you have more than one instance of a single character in an alternation. So (?:a|the) is allowed, but (?:a|e|i|o|u) is not.

CONFIGURATION

This Policy is not configurable except for the standard options.

CREDITS

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