String::Range::Expand - Expand range-like strings

SYNOPSIS
========

    use String::Range::Expand;

    print "$_\n" for expand_range('host[aa-ac,^ab,ae][01-04,^02-03]');

    # Prints ...
        # hostaa01
        # hostaa04
        # hostac01
        # hostac04
        # hostae01
        # hostae04

DESCRIPTION
===========

This module provides functions to expand a string that contains
range-like expressions. This is something that is usually useful when
working with hostnames, but can be used elsewhere too.

FUNCTIONS
=========

expand_range($string)
---------------------

    my @list = expand_range('...');

This function accept a single string, evaluates expressions in those
strings and returns a list with all avaialble permutations. Ranges with
limits are expanded using the Range Operator.

    my @list = expand_range('[aa-ad]'); # This is identical to ('aa' .. 'ad')

The following formats are recognized and evaluated

    my @list = expand_range('foo[bar,baz]');        # Comma separated list
    my @list = expand_range('foo[aa-ad,^ab]');      # Negated element
    my @list = expand_range('foo[aa-ag,^ab-ad]');   # Negated range

SEE ALSO
========

-   SSH::Batch

This is an extremely useful distribution if you are working with
hostnames. String::Range::Expand was inspired by this distribution, and
provides only a subset of features of SSH::Batch

-   String::Glob::Permute

Pretty similar, but does not evaluate alphabetical ranges

-   Text::Glob::Expand

Like String::Glob::Permute, it does not evaluate alphabetical ranges.
But it does provide some additional functionality like setting upper
limits and formatting.

BUGS AND LIMITATIONS
====================

This module does not attempt to limit the number of permutations for an
expression.
