Perl::Critic::Policy::Variables::RequireNegativeIndices(User Contributed Perl DocumentatPerl::Critic::Policy::Variables::RequireNegativeIndices(3)NAME
Perl::Critic::Policy::Variables::RequireNegativeIndices - Negative array index should be used.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Perl treats a negative array subscript as an offset from the end. Given this, the preferred way to get the last element is $x[-1], not
$x[$#x] or $x[@x-1], and the preferred way to get the next-to-last is $x[-2], not "$x[$#x-1" or $x[@x-2].
The biggest argument against the non-preferred forms is that their semantics change when the computed index becomes negative. If @x
contains at least two elements, $x[$#x-1] and $x[@x-2] are equivalent to $x[-2]. But if it contains a single element, $x[$#x-1] and
$x[@x-2] are both equivalent to $x[-1]. Simply put, the preferred form is more likely to do what you actually want.
As Conway points out, the preferred forms also perform better, are more readable, and are easier to maintain.
This policy notices all of the simple forms of the above problem, but does not recognize any of these more complex examples:
$some->[$data_structure]->[$#{$some->[$data_structure]} -1];
my $ref = @arr; $ref->[$#arr];
CONFIGURATION
This Policy is not configurable except for the standard options.
