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).

Any other string will fall through to the next plugin.

BUGS

SEE ALSO

Acme::Range and List::Maker, although these are somewhat broken because they replace glob() globally.
