Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters

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.
