Range::HashIter - Generate a tied-hash iterator for range
This document describes version 0.001 of Range::HashIter (from Perl distribution Range-HashIter), released on 2019-05-12.
use Range::HashIter qw(range_hashiter); my $iter = range_hashiter(1, 10); while (my ($key, undef) = each %$iter) { ... } # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
You can add step:
my $iter = range_hashiter(1, 10, 2); # 1, 3, 5, 7, 9
You can use alphanumeric strings too since ++ has some extra builtin magic (see perlop):
++
$iter = range_hashiter("zx", "aab"); # zx, zy, zz, aaa, aab
Infinite list:
$iter = range_hashiter(1, Inf); # 1, 2, 3, ...
PROOF OF CONCEPT.
This module offers a tied-hash-based iterator that you can use using while() and each(). It's most probably useful as a proof of concept only.
