Getopt::EX::Numbers(3)User Contributed Perl DocumentatioGetopt::EX::Numbers(3)

NAME
       Getopt::EX::Numbers - module to handle number parameters

SYNOPSIS
       use Getopt::EX::Numbers;

       my $obj = Getopt::EX::Numbers->new(max => 100);

       $obj->parse("start:end:step:length"); $obj->range;

       $obj->parse("start:end:step:length")->sequence;

       Getopt::EX::Numbers->new->parse("1:10:2")->sequence;

FORMAT
       Number format is	composed by four elements: "start", "end", "step" and
       "length".  All elements are optional.

	   1	       1
	   1:3	       1,2,3
	   1:20:5      1,     6,     11,       16
	   1:20:5:3    1,2,3, 6,7,8, 11,12,13, 16,17,18

       When "start" is omitted,	minimum	value is used, which is	zero by
       default.	 If the	object is initialized with "max" value,	"end" element
       can be omitted.

	   ::	       all
	   ::2	       even numbers
	   1::2	       odd numbers

       If "start" and "end" number is negative,	they are subtracted from the
       maximum number.	If the "end" number is prefixed	by plus	(`+') sign, it
       is summed to "start" number.  Next examples produce top and last	10
       numbers.

	   :+9	       top 10 numbers
	   -9:	       last 10 numbers

METHOD
       new ( [ min => n	] , [ max => m ] )
	   Create object with optional parameter min and max.

       parse(spec)
	   Accept number description and parse it.  Return object itself.

       range
	   Return number range list:

	       ( [ n0, m0 ], [ n1, m1 ], ... )

       sequence
	   Return number sequence:

	       ( n0 .. m0, n1 .. m1, ... )
