Data::CGIForm is a Perl module with form data interface.

Data::CGIForm is yet another way to parse and handle CGI form data. The main motivation behind this module was a simple specification based validator that could handle multiple values.
You probably dont want to use this module. CGI::Validate is a much more feature complete take on getting this sort of work done. You may then ask why this is on the CPAN, I ask that of myself from time to time....

SYNOPSIS

my %spec = (
username => qr/^([a-z0-9]+)$/,
password => {
regexp => qr/^([a-z0-9+])$/,
filter => [qw(strip_leading_ws, strip_trailing_ws)],
},
email => {
regexp => qr/^([a-z0-9@.]+)$/,
filter => &qualify_domain,
optional => 1,
errors => {
empty => You didnt enter an email address.,
invalid => Bad [% key %]: "[% value %]",
},
extra_test => &check_email_addr,
},
email2 => {
equal_to => email,
errors => {
unequal => Both email addresses must be the same.,
},
},
);

my $r = $ENV{MOD_PERL} ? Apache::Request->instance : CGI->new;

my $form = Data::CGIForm->new(datasource => $r, spec => %spec);


my @params = $form->params;
foreach $param (@params) {
next unless my $error_string = $form->error($param);

print STDERR $error_string;
}

if ($form->error(username)) {
handle_error($form->username, $form->error(username));
}

my $email = $form->param(email);
my $password = $form->password;

Data::ICal is a Perl module that generates iCalendar (RFC 2445) calendar files.

SYNOPSIS

use Data::ICal;

my $calendar = Data::ICal->new();

my $vtodo = Data::ICal::Entry::Todo->new();
$vtodo->add_properties(
# ... see Data::ICal::Entry::Todo documentation
);

# ... or

$calendar = Data::ICal->new(filename => foo.ics); # parse existing file
$calendar = Data::ICal->new(data => BEGIN:VCALENDAR...); # parse existing file


$calendar->add_entry($vtodo);

print $calendar->as_string;

# Or, if youre printing to something you want google to read:
print $calendar->as_string(fold => 0);

A Data::ICal object represents a VCALENDAR object as defined in the iCalendar protocol (RFC 2445, MIME type "text/calendar"), as implemented in many popular calendaring programs such as Apples iCal.

Each Data::ICal object is a collection of "entries", which are objects of a subclass of Data::ICal::Entry. The types of entries defined by iCalendar (which refers to them as "components") include events, to-do items, journal entries, free/busy time indicators, and time zone descriptors; in addition, events and to-do items can contain alarm entries. (Currently, Data::ICal only implements to-do items and events.)
Data::ICal is a subclass of Data::ICal::Entry; see its manpage for more methods applicable to Data::ICal.

GNU DDD is a graphical front-end for command-line debuggers such as GDB, DBX, WDB, Ladebug, JDB, XDB, the Perl debugger, the bash debugger, or the Python debugger.

Besides "usual front-end features such as viewing source texts, DDD has become famous through its interactive graphical data display, where data structures are displayed as graphs.

Data::Serializer package contains modules that serialize data structures.

SYNOPSIS

use Data::Serializer;

$obj = Data::Serializer->new();

$obj = Data::Serializer->new(
serializer => Storable,
digester => MD5,
cipher => DES,
secret => my secret,
compress => 1,
);

$serialized = $obj->serialize({a => [1,2,3],b => 5});
$deserialized = $obj->deserialize($serialized);
print "$deserialized->{b}n";

Provides a unified interface to the various serializing modules currently available. Adds the functionality of both compression and encryption.

EXAMPLES

Please see Data::Serializer::Cookbook(3)

METHODS

new - constructor
$obj = Data::Serializer->new();


$obj = Data::Serializer->new(
serializer => Data::Dumper,
digester => SHA-256,
cipher => Blowfish,
secret => undef,
portable => 1,
compress => 0,
serializer_token => 1,
options => {},
);

new is the constructor object for Data::Serializer objects.

The default serializer is Data::Dumper
The default digester is SHA-256
The default cipher is Blowfish
The default secret is undef
The default portable is 1
The default encoding is hex
The default compress is 0
The default compressor is Compress::Zlib
The default serializer_token is 1
The default options is {} (pass nothing on to serializer)
serialize - serialize reference

$serialized = $obj->serialize({a => [1,2,3],b => 5});

Serializes the reference specified.
Will compress if compress is a true value.
Will encrypt if secret is defined.
deserialize - deserialize reference

$deserialized = $obj->deserialize($serialized);

Reverses the process of serialization and returns a copy of the original serialized reference.

freeze - synonym for serialize
$serialized = $obj->freeze({a => [1,2,3],b => 5});

thaw - synonym for deserialize
$deserialized = $obj->thaw($serialized);

raw_serialize - serialize reference in raw form
$serialized = $obj->raw_serialize({a => [1,2,3],b => 5});

This is a straight pass through to the underlying serializer, nothing else is done. (no encoding, encryption, compression, etc)

raw_deserialize - deserialize reference in raw form
$deserialized = $obj->raw_deserialize($serialized);

This is a straight pass through to the underlying serializer, nothing else is done. (no encoding, encryption, compression, etc)

secret - specify secret for use with encryption
$obj->secret(mysecret);

Changes setting of secret for the Data::Serializer object. Can also be set in the constructor. If specified than the object will utilize encryption.

portable - encodes/decodes serialized data

Uses encoding method to ascii armor serialized data

Aids in the portability of serialized data.

compress - compression of data

Compresses serialized data. Default is not to use it. Will compress if set to a true value $obj->compress(1);

serializer - change the serializer

Currently have 8 supported serializers: Storable, FreezeThaw, Data::Denter, Config::General, YAML, PHP::Serialization, XML::Dumper, and Data::Dumper.
Default is to use Data::Dumper.

Each serializer has its own caveats about usage especially when dealing with cyclical data structures or CODE references. Please see the appropriate documentation in those modules for further information.

cipher - change the cipher method

Utilizes Crypt::CBC and can support any cipher method that it supports.

digester - change digesting method

Uses Digest so can support any digesting method that it supports. Digesting function is used internally by the encryption routine as part of data verification.

compressor - changes compresing module

This method is included for possible future inclusion of alternate compression method Currently Compress::Zlib is the only supported compressor.

encoding - change encoding method

Encodes data structure in ascii friendly manner. Currently the only valid options are hex, or b64.

The b64 option uses Base64 encoding provided by MIME::Base64, but strips out newlines.

serializer_token - add usage hint to data

Data::Serializer prepends a token that identifies what was used to process its data. This is used internally to allow runtime determination of how to extract Serialized data. Disabling this feature is not recommended.

options - pass options through to underlying serializer

Currently is only supported by Config::General, and XML::Dumper.

my $obj = Data::Serializer->new(serializer => Config::General,
options => {
-LowerCaseNames => 1,
-UseApacheInclude => 1,
-MergeDuplicateBlocks => 1,
-AutoTrue => 1,
-InterPolateVars => 1
},
) or die "$!n";

or

my $obj = Data::Serializer->new(serializer => XML::Dumper,
options => { dtd => 1, }
) or die "$!n";
store - serialize data and write it to a file (or file handle)
$obj->store({a => [1,2,3],b => 5},$file, [$mode, $perm]);

or

$obj->store({a => [1,2,3],b => 5},$fh);

Serializes the reference specified using the serialize method and writes it out to the specified file or filehandle.

If a file path is specified you may specify an optional mode and permission as the next two arguments. See IO::File for examples.

Trips an exception if it is unable to write to the specified file.

retrieve - read data from file (or file handle) and return it after deserialization

my $ref = $obj->retrieve($file);

or

my $ref = $obj->retrieve($fh);

Reads first line of supplied file or filehandle and returns it deserialized.

Data::ICal::Entry::Todo is a Perl module that represents a to-do entry in an iCalendar file.

SYNOPSIS

my $vtodo = Data::ICal::Entry::Todo->new();
$vtodo->add_properties(
summary => "go to sleep",
status => INCOMPLETE,
# Dat*e*::ICal is not a typo here
dtstart => Date::ICal->new( epoch => time )->ical,
);

$calendar->add_entry($vtodo);

$vtodo->add_entry($alarm);

A Data::ICal::Entry::Todo object represents a single to-do entry in an iCalendar file. (Note that the iCalendar RFC refers to entries as "components".) It is a subclass of Data::ICal::Entry and accepts all of its methods.

Data::Diff is a data structure comparison module.

SYNOPSIS

use Data::Diff qw(diff);

# simple procedural interface to raw difference output
$out = diff( $a, $b );

# OO usage
$diff = Data::Diff->new( $a, $b );

$new = $diff->apply();
$changes = $diff->diff_a();

Data::Diff computes the differences between two abirtray complex data structures.

METHODS

Creation

new Data::Diff( $a, $b, $options )

Creates and retruns a new Data::Diff object with the differences between $a and $b.

Access

apply( $options )

Returns the result of applying one side over the other.

raw()

Returns the internal data structure that describes the differences at all levels within.

Functions

Diff( $a, $b, $options )

Compares the two arguments $a and $b and returns the raw comparison between the two.

EXPORT

Nothing by default but you can choose to export the non-OO function Diff().
