NAME
Perl::Critic::Policy::RegularExpressions::ProhibitEnumeratedClasses - Use named character classes instead of explicit character lists.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
This policy is not for everyone! If you are working in pure ASCII, then disable it now or you may see some false violations. On the other hand many of us are working in a multilingual world with an extended character set, probably Unicode. In that world, patterns like "m/[A-Z]/" can be a source of bugs when you really meant "m/p{IsUpper}/". This policy catches a selection of possible incorrect character class usage. Specifically, the patterns are: "[ f ]" vs. "s" "[ ]" vs. "s" (because many people forget "f") "[A-Za-z0-9_]" vs. "w" "[A-Za-z]" vs. "p{IsAlphabetic}" "[A-Z]" vs. "p{IsUpper}" "[a-z]" vs. "p{IsLower}" "[0-9]" vs. "d" "[^w]" vs. "W" "[^s]" vs. "S"
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.
