Hello world,
I was wondering if there is a nicer way to write the following code (in AWK):
awk '
FNR==NR&&$1~/^m$/{tok1=1}
FNR==NR&&$1~/^m10$/{tok1=1}
' my_file
In fact, it looks for m2, m4, m6, m8 and m10 and then return a positive flag. The problem is how to define 10 thanks... (3 Replies)

Perl::Critic::Policy::Variables::RequireNegativeIndices(User Contributed Perl DocumentPerl::Critic::Policy::Variables::RequireNegativeIndices(3pm)NAME
Perl::Critic::Policy::Variables::RequireNegativeIndices - Negative array index should be used.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway points out that
$arr[$#arr];
$arr[$#arr-1];
$arr[@arr-1];
$arr[@arr-2];
are equivalent to
$arr[-1];
$arr[-2];
$arr[-1];
$arr[-2];
and the latter are more readable, performant and maintainable. The latter is because the programmer no longer needs to keep two variable
names matched.
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.
