NAME Data::Type - versatile data and value types VERSION 0.01.03 (Tue Jan 14 04:07:18 2003) DESCRIPTION This module supports versatile data and value types. Out of the ordinary it supports parameterised types (like databases have i.e. VARCHAR(80) ). When you try to feed a typed variable against some odd data, this module explains what he would have expected. SYNOPSIS use Data::Type qw(:all); use Error qw(:try); try { verify $email , EMAIL; verify $homepage , URI('http'); verify $server_ip , IP('v4'); verify $cc , CREDITCARD( 'MASTERCARD', 'VISA' ); verify $answer_a , YESNO; verify $gender , GENDER; verify 'one' , ENUM( qw(one two three) ); verify [qw(two six)], SET( qw(one two three four five six) ) ); verify 'A35231AH1' , CINS; verify '14565935' , ISSN; verify 'DE' , LANGCODE; verify 'German' , LANGNAME; verify '012345678905', UPC(); verify '5276440065421319', CREDITCARD( 'MASTERCARD' ) ); verify 'ATGCAAAT' , BIO::DNA; verify 'AUGGGAAAU' , BIO::RNA; verify '01001001110110101', BINARY; verify '0F 0C 0A', HEX; verify '234' , NUM( 20 ); verify '1' , BOOL( 'true' ); verify '100' , INT; verify '1.1' , REAL; my $foo = bless( \'123', 'SomeThing' ); verify $foo , REF; verify $foo , REF( qw(SomeThing Else) ); verify [ 'bar' ] , REF( 'ARRAY' ); verify ' ' x 20 , VARCHAR( 20 ); verify '2001-01-01' , DATE( 'MYSQL' ); verify '16 Nov 94 22:28:20 PST' , DATE( 'DATEPARSE' ); verify '9999-12-31 23:59:59', DATETIME; verify '1970-01-01 00:00:00', TIMESTAMP; verify '-838:59:59' , TIME; verify '2155' , YEAR; verify '69' , YEAR(2); verify '0' x 20 , TINYTEXT; verify '0' x 20 , MEDIUMTEXT; verify '0' x 20 , LONGTEXT; verify '0' x 20 , TEXT; } catch Type::Exception with { my $e = shift; printf "Expected '%s' %s at %s line %s\n", $e->value, $e->type->info, $e->was_file, $e->was_line; foreach my $entry ( testplan( $e->type ) ) { printf "\texpecting it %s %s ", $entry->[1] ?

CREDITCARD This type isn't tested at all and nobody should rely on it without rigorous testing. Supported are: 'Diners Club', 'Australian BankCard', 'VISA', 'Discover/Novus', 'JCB', 'MasterCard', 'Carte Blache', 'American Express'. They are parameterised as: DINERS, BANKCARD, VISA, DISCOVER, JCB, MASTERCARD, BLACHE, AMEX. CONTRIBUTIONS The author is happy to receive more types (formats) and add to this library. If you have a algorithm/regex for validating it, the better. Just email me. CPAN PREREQUISITES It utilizes various CPAN modules as partially listed here.
