Perl::Critic::Policy::ValuesAndExpressions::ProhibitNoisUsertContributed Perl Perl::Critic::Policy::ValuesAndExpressions::ProhibitNoisyQuotes(3pm) NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitNoisyQuotes - Use "q{}" or "qq{}" instead of quotes for awkward-looking strings. AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Don't use quotes for one or two-character strings of non-alphanumeric characters (i.e. noise). These tend to be hard to read. For legibility, use "q{}" or a named value. However, braces, parentheses, and brackets tend do to look better in quotes, so those are allowed. $str = join ',', @list; #not ok $str = join ",", @list; #not ok $str = join q{,}, @list; #better $COMMA = q{,}; $str = join $COMMA, @list; #best $lbrace = '('; #ok $rbrace = ')'; #ok print '(', @list, ')'; #ok CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO

Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write "q{}" instead of "''". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Don't use quotes for an empty string or any string that is pure whitespace. Instead, use "q{}" to improve legibility. Better still, created named values like this. Use the "x" operator to repeat characters. $message = ''; #not ok $message = ""; #not ok $message = " "; #not ok $message = q{}; #better $message = q{ } #better $EMPTY = q{}; $message = $EMPTY; #best $SPACE = q{ }; $message = $SPACE x 5; #best CONFIGURATION
