Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters(3)
NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters -
Write ""\N{DELETE}"" instead of ""\x7F"", etc.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Escaped numeric values are hard to read and debug. Instead, use named
values. The syntax is less compact, but dramatically more readable.
$str = "\x7F\x06\x22Z"; # not ok
use charnames ':full';
$str = "\N{DELETE}\N{ACKNOWLEDGE}\N{CANCEL}Z"; # ok
CONFIGURATION
This Policy is not configurable except for the standard options.
