Regexp::NumRange is a package for generating regular expression strings. These strings can be used in a regular expression to correctly match numeric strings within only a specified range.

Example Usage:

  use Test::More;
  use Regexp::NumRange qw/ rx_max /;

  my $rx = rx_max(255);

  like '100', qr/^$rx$/, '100 is less than 255';
  unlike '256', qr/^$rx$/, '256 is greater tha 255';

EXPORT ^

Exports Available:

  use Regexp::NumRange qw/ rx_max rx_range /;

SUBROUTINES/METHODS ^

rx_range

Create a regex string between two arbitrary integers.

  use Test::More;
  use Regexp::NumRange qw/ rx_range /;

  my $string = rx_range(256, 1024);
  my $rx = qr/^$string$/;

  ok "10" !~ $rx;
  ok "300" =~ $rx;
  ok "2000" !~ $rx;

rx_max

Create a regex string between 0 and an arbitrary integer.

  my $rx_string = rx_max(1024); # create a string matching numbers between 0 and 1024
  is $rx_string, '(102[0-4]|10[0-1][0-9]|0?[0-9]{1,3})';
