NAME
Range::HandleIter - Generate a tied-handle iterator for range
VERSION
This document describes version 0.001 of Range::HandleIter (from Perl
distribution Range-HandleIter), released on 2019-05-12.
SYNOPSIS
use Range::HandleIter qw(range_handleiter);
my $iter = range_handleiter(1, 10);
while (<$iter>) { ... } # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
You can add step:
my $iter = range_handleiter(1, 10, 2); # 1, 3, 5, 7, 9
You can use alphanumeric strings too since "++" has some extra builtin
magic (see perlop):
$iter = range_handleiter("zx", "aab"); # zx, zy, zz, aaa, aab
Infinite list:
$iter = range_handleiter(1, Inf); # 1, 2, 3, ...
DESCRIPTION
PROOF OF CONCEPT.
This module offers a tied-handle-based iterator that you can use using
while() and the diamond operator. It's most probably useful as a proof
of concept only.
FUNCTIONS
range_handleiter($start, $end [ , $step ]) => filehandle
