NAME

Acme::Globule::Range - alternative range operator

SYNOPSIS

 use Acme::Globule qw( Range );

 foreach (<10..1>) {
   print "$_... ";
 }
 print "Lift-off!\n";

 # put down that crack pipe...
 sub my_keys(\%) {
   my @hash = %{ $_[0] };
  return @hash[ glob("0,2..$#hash") ];
 }

 sub my_values(\%) {
   my @hash = %{ $_[0] };
  return @hash[ glob("1,3..$#hash") ];
 }

DESCRIPTION

This is a Acme::Globule plugin that makes glob() do range operations. The following range formats are supported:

A..Z: Returns the integers between A and Z. If Z is lower than A, this will return a reversed range. Thus <1..9> is (1..9) and <9..1> is (reverse 1..9).
A,B..Z: Returns the integers between A and Z with a step such that the second value is B. Thus <1,3..9> is (1, 3, 5, 7, 9).
A..Y,Z: Returns the integers between A and Z with a step such that the next to last value is Y. Thus <1..7,9> is (1, 3, 5, 7, 9).
