👑 NAME 👑

File::KDBX::Object — a KDBX database object 🦋 (it's giving File::KDBX::Object(3pm), user contributed Perl documentation, and honestly? iconic.)

🎀 VERSION 🎀

version 0.906 ✨ we stay current bestie

💅 DESCRIPTION 💅

okay so. KDBX is an object database 🔥 and this class? This class is an abstract class that represents an object. Meaning: do NOT use this class directly 🙈 use its subclasses instead:

File::KDBX::Entry
File::KDBX::Group

There's a whole bunch of functionality that both types of objects share, and that's literally what this class is here to provide. sharing is caring 💖

Every object can be connected with a File::KDBX database, or it can be disconnected. A disconnected object exists in memory but will not be persisted when dumping a database. Also possible: an object can be connected with a database but not actually be part of the object tree — like, it's not the root group, not any subroup, not any entry 🫠. A disconnected object, or an object that isn't part of a database's object tree, can be added to a database using one of these:

"add_entry" in File::KDBX
"add_group" in File::KDBX
"add_entry" in File::KDBX::Group
"add_group" in File::KDBX::Group
"add_historical_entry" in File::KDBX::Entry

You can copy or move objects between databases, but 🚨 DO NOT include the same object in more than one database at once 🚨 or you could get some strange aliasing effects (i.e. changes in one database might affect another in unexpected ways). And that leads to those difficult-to-debug problems that make you want to scream into a pillow 😭. It is similarly not safe or valid to add the same object multiple times to the same database. Like, for example:

💀 do not be this girl:

my $entry = File::KDBX::Entry->(title => 'Whatever');

# DO NOT DO THIS:
$kdbx->add_entry($entry);
$another_kdbx->add_entry($entry);

# DO NOT DO THIS:
$kdbx->add_entry($entry);
$kdbx->add_entry($entry); # again

Instead, do this 💅:

# Copy an entry to multiple databases:
$kdbx->add_entry($entry);
$another_kdbx->add_entry($entry->clone);

# OR move an existing entry from one database to another:
$another_kdbx->add_entry($entry->remove);

🦋 ATTRIBUTES 🦋

💖 kdbx

$kdbx = $object->kdbx;
$object->kdbx($kdbx);

Get or set the File::KDBX instance connected with this object. Throws if the object is disconnected. Other object methods might only work if the object is connected to a database, so they might also throw if the object is disconnected 😤. If you're not sure whether an object is connected, try "is_connected".

🎀 uuid

128-bit UUID identifying the object within the connected database ✨

🌸 icon_id

Integer representing a default icon. See ":icon" in File::KDBX::Constants for valid values.

🧚 custom_icon_uuid

128-bit UUID identifying a custom icon within the connected database.

👑 tags

Text string with arbitrary tags which can be used to build a taxonomy. organize ur life bestie 🫶

🦋 previous_parent_group

128-bit UUID identifying a group within the connected database the previously contained the object.

⭐ last_modification_time

Date and time when the entry was last modified.

💜 creation_time

Date and time when the entry was created.

🌈 last_access_time

Date and time when the entry was last accessed.

🍓 expiry_time

Date and time when the entry expired or will expire.

💅 expires

Boolean value indicating whether or not an entry is expired.

✨ usage_count

The number of times an entry has been used, which typically means how many times the Password string has been accessed.

🔥 location_changed

Date and time when the entry was last moved to a different parent group.

okay that's the first half, and there is so much more coming — stay with me 🫶

✨ METHODS ✨

new

$object = File::KDBX::Object->new;
$object = File::KDBX::Object->new(%attributes);
$object = File::KDBX::Object->new(\%data);
$object = File::KDBX::Object->new(\%data, $kdbx);

Construct a new KDBX object. slay. ✨

There is a subtlety to take note of. There is a significant difference between:

File::KDBX::Entry->new(username => 'iambatman');

and:

File::KDBX::Entry->new({username => 'iambatman'}); # WRONG

In the first, an empty object is first created and then initialized with whatever attributes are given. In the second, a hashref is blessed and essentially becomes the object. The significance is that the hashref key-value pairs will remain as-is so the structure is expected to adhere to the shape of a raw Object (which varies based on the type of object), whereas with the first the attributes will set the structure in the correct way (just like using the object accessors / getters / setters).

The second example isn't generally wrong -- this type of construction is supported for a reason, to allow for working with KDBX objects at a low level -- but it is wrong in this specific case only because "{username => $str}" isn't a valid raw KDBX entry object. The "username" attribute is really a proxy for the "UserName" string, so the equivalent raw entry object should be "{strings => {UserName => {value => $str}}}". These are roughly equivalent:

File::KDBX::Entry->new(username => 'iambatman');
File::KDBX::Entry->new({strings => {UserName => {value => 'iambatman'}}});

If this explanation went over your head, that's fine. Just stick with the attributes since they are typically easier to use correctly and provide the most convenience. If in the future you think of some kind of KDBX object manipulation you want to do that isn't supported by the accessors and methods, just know you can access an object's data directly.

init

$object = $object->init(%attributes);

Called by the constructor to set attributes. You normally should not call this. hands off, bestie. 🙈

wrap

$object = File::KDBX::Object->wrap($object);

Ensure that a KDBX object is blessed. iconic.

label

$label = $object->label;
$object->label($label);

Get or set the object's label, a text string that can act as a non-unique identifier. For an entry, the label is its title string. For a group, the label is its name. got it.

clone

$object_copy = $object->clone(%options);
$object_copy = File::KDBX::Object->new($object);

Make a clone of an object. By default the clone is indeed an exact copy that is connected to the same database but not actually included in the object tree (i.e. it has no parent group). Some options are allowed to get different effects:

new_uuid — If set, generate a new UUID for the copy (default: false)
parent — If set, add the copy to the same parent group, if any (default: false)
relabel — If set, append " - Copy" to the object's title or name (default: false)
entries — If set, copy child entries, if any (default: true)
groups — If set, copy child groups, if any (default: true)
history — If set, copy entry history, if any (default: true)
reference_password — Toggle whether or not cloned entry's Password string should be set as a field reference to the original entry's Password string (default: false)
reference_username — Toggle whether or not cloned entry's UserName string should be set as a field reference to the original entry's UserName string (default: false)

is_connected

$bool = $object->is_connected;

Determine whether or not an object is connected to a database. vibe check on the connection.

id

$string_uuid = $object->id;
$string_uuid = $object->id($delimiter);

Get the unique identifier for this object as a formatted UUID string, typically for display purposes. You could use this to compare with other identifiers formatted with the same delimiter, but it is more efficient to use the raw UUID for that purpose (see "uuid").

A delimiter can optionally be provided to break up the UUID string visually. See "format_uuid" in File::KDBX::Util.

group

$parent_group = $object->group;
$object->group($parent_group);

Get or set the parent group to which an object belongs or "undef" if it belongs to no group. family tree energy.

lineage

\@lineage = $object->lineage;
\@lineage = $object->lineage($base_group);

Get the direct line of ancestors from $base_group (default: the root group) to an object. The lineage includes the base group but not the target object. Returns "undef" if the target is not in the database structure. Returns an empty arrayref if the object itself is a root group.

remove

$object = $object->remove(%options);

Remove an object from its parent. If the object is a group, all contained objects stay with the object and so are removed as well, just like cutting off a branch takes the leaves as well. Options:

signal — Whether or not to signal the removal to the connected database (default: true)

recycle

$object = $object->recycle;

Remove an object from its parent and add it to the connected database's recycle bin group. sustainable queen. ♻️

recycle_or_remove

$object = $object->recycle_or_remove;

Recycle or remove an object, depending on the connected database's "recycle_bin_enabled" in File::KDBX. If the object is not connected to a database or is already in the recycle bin, remove it.

is_recycled

$bool = $object->is_recycled;

Get whether or not an object is in a recycle bin. trash or treasure?

@tags = $entry->tag_list;

Get a list of tags, split from "tag" using delimiters ",", ".", ":", ";" and whitespace.

custom_icon

$image_data = $object->custom_icon;
$image_data = $object->custom_icon($image_data, %attributes);

Get or set an icon image. Returns "undef" if there is no custom icon set. Setting a custom icon will change the "custom_icon_uuid" attribute.

Custom icon attributes (supported in KDBX4.1 and greater):

name — Name of the icon (text)
last_modification_time — Just what it says (datetime)

custom_data

\%all_data = $object->custom_data;
$object->custom_data(\%all_data);

\%data = $object->custom_data($key);
$object->custom_data($key => \%data);
$object->custom_data(%data);
$object->custom_data(key => $value, %data);

Get and set custom data. Custom data is metadata associated with an object. It is a set of key-value pairs used to store arbitrary data, usually used by software like plug-ins to keep track of state rather than by end users.

Each data item can have a few attributes associated with it.

key — A unique text string identifier used to look up the data item (required)
value — A text string value (required)
last_modification_time (optional, KDBX4.1+)

custom_data_value

$value = $object->custom_data_value($key);

Exactly the same as "custom_data" except returns just the custom data's value rather than a structure of attributes. This is a shortcut for:

my $data = $object->custom_data($key);
my $value = defined $data ? $data->{value} : undef;

begin_work

$txn = $object->begin_work(%options);
$object->begin_work(%options);

Begin a new transaction. Returns a File::KDBX::Transaction object that can be scoped to ensure a rollback occurs if exceptions are thrown. Alternatively, if called in void context, there will be no File::KDBX::Transaction and it is instead your responsibility to call "commit" or "rollback" as appropriate. It is undefined behavior to call these if a File::KDBX::Transaction exists. Recursive transactions are allowed.

Signals created during a transaction are delayed until all transactions are resolved. If the outermost transaction is committed, then the signals are de-duplicated and delivered. Otherwise the signals are dropped. This means that the KDBX database will not fix broken references or mark itself dirty until after the transaction is committed.

How it works: With the beginning of a transaction, a snapshot of the object is created. In the event of a rollback, the object's data is replaced with data from the snapshot.

By default, the snapshot is shallow (i.e. does not include subgroups, entries or historical entries). This means that only modifications to the object itself (its data, fields, strings, etc.) are atomic; modifications to subgroups etc., including adding or removing items, are auto-committed instantly and will persist regardless of the result of the pending transaction. You can override this for groups, entries and history independently using options:

entries — If set, snapshot entries within a group, deeply (default: false)
groups — If set, snapshot subgroups within a group, deeply (default: false)
history — If set, snapshot historical entries within an entry (default: false)

For example, if you begin a transaction on a group object using the "entries" option, like this:

$group->begin_work(entries => 1);

Then if you modify any of the group's entries OR add new entries OR delete entries, all of that will be undone if the transaction is rolled back. With a default-configured transaction, however, changes to entries are kept even if the transaction is rolled back.

commit

$object->commit;

Commit a transaction, making updates to $object permanent. Returns itself to allow method chaining. periodt. 💅

rollback

$object->rollback;

Roll back the most recent transaction, throwing away any updates to the "object" made since the transaction began. Returns itself to allow method chaining. undo queen. ↩️
