use Getopt::toHash;

--Grab all arguments, return into hash ref. my $Args = Getopt::toHash->get_em();

Everything else is optional beyond this point.

--Validation If you want the module to only make sure certain arguments are there and not validate them. $Args->validate('required'=>['-a','-b','-c']);

The Module can validate on 7 Different constraints REGEXP - {'REGEXP=>'^[-+]?[0-9]'} - Specify a regex the passed data must comply with. MINMAX - {'MINMAX'=>{min=>20,max=>40}} - Specify minimum and maximum numbers the argument must be. GREATER_THAN - {'GREATER_THAN'=>{min=>20}} - Specify a minimum number the argument must be. LESS_THAN - {'LESS_THAN'=>{max=>40}} - Specify a maximum number the argument must be lower than. ASCII - ['ASCII'] - The argument must be any ASCII text with spaces allowed. NOSPACES - ['NOSPACES'] - The argument must have no spaces. ANY - ['ANY'] - The argument must be defined.

You can validate each argument on as many types of validation as you want by stringing together each array ref or hash. The Argument must pass each constraint

--Example 1 - Validating with a inline object. $Args->validate( '-a'=>[ 'ASCII','NOSPACES',{ 'MINMAX'=>{min=>20,max=>40} } ] );

--Example 2 - Validating with a hash spec. my %spec = ( '-a'=>[ 'ASCII','NOSPACES', {'MINMAX'=>{min=>20,max=>40} } ] ); $Args->validate(%spec);

The module will display error messages and die on failed validation by default. If you dont want this you can pass... $Args->validate( no_errors=>'1','-a'=>[ 'ASCII','NOSPACES',{ 'MINMAX'=>{min=>20,max=>40} } ] );
