`khard.carddav_object`¶

Classes and logic to handle vCards in khard.

This module explicitly supports the vCard specifications version 3.0 and 4.0 which can be found here: - version 3.0: https://tools.ietf.org/html/rfc2426 - version 4.0: https://tools.ietf.org/html/rfc6350

khard.carddav_object.Query¶

khard.carddav_object.convert_to_vcard(name: str, value: Union[str, List[str]], allowed_object_type: ObjectType) → Union[str, List[str]]¶

converts user input into vcard compatible data structures

Parameters

name – object name, only required for error messages
value – user input
allowed_object_type – set the accepted return type for vcard attribute

Returns

cleaned user input, ready for vcard or a ValueError

khard.carddav_object.multi_property_key(item: Union[str, Dict]) → List¶

key function to pass to sorted(), allowing sorting of dicts with lists and strings. Dicts will be sorted by their label, after other types.

Parameters: item (a dict with a single entry or any sortable type) – member of the list being sorted
Returns: a list with two members. The first is int(isinstance(item, dict). The second is either the key from the dict or the unchanged item if it is not a dict.
Return type: list(int, type(item)) or list(int, str)

class khard.carddav_object.VCardWrapper(vcard: vobject.vCard, version: Optional[str] = None)¶

Wrapper class around a vobject.vCard object.

This class can wrap a single vCard and presents its data in a manner suitable for khard. Additionally some details of the vCard specifications in RFC 2426 (version 3.0) and RFC 6350 (version 4.0) that are not enforced by the vobject library are enforced here.

_default_version = 3.0¶

_supported_versions = ['3.0', '4.0']¶

phone_types_v3 = ['bbs', 'car', 'cell', 'fax', 'home', 'isdn', 'msg', 'modem', 'pager', 'pcs', 'video', 'voice', 'work']¶

email_types_v3 = ['home', 'internet', 'work', 'x400']¶

address_types_v3 = ['dom', 'intl', 'home', 'parcel', 'postal', 'work']¶

phone_types_v4 = ['text', 'voice', 'fax', 'cell', 'video', 'pager', 'textphone', 'home', 'work']¶

email_types_v4 = ['home', 'internet', 'work']¶

address_types_v4 = ['home', 'work']¶

__str__(self)¶

_get_string_field(self, field: str)¶

Get a string field from the underlying vCard.

Parameters: field – the field value to get
Returns: the field value or the empty string

_get_multi_property(self, name: str)¶

Get a vCard property that can exist more than once.

It does not matter what the individual vcard properties store as their value. This function returnes them untouched inside an agregating list.

If the property is part of a group containing exactly two items, with exactly one ABLABEL. the property will be prefixed with that ABLABEL.

Parameters: name – the name of the property (should be UPPER case)
Returns: the values from all occurences of the named property

_delete_vcard_object(self, name: str)¶

Delete all fields with the given name from the underlying vCard.

If a field that will be deleted is in a group with an X-ABLABEL field, that X-ABLABEL field will also be deleted. These fields are commonly added by the Apple address book to attach custom labels to some fields.

Parameters: name – the name of the fields to delete

static _parse_type_value(types: List[str], supported_types: List[str])¶

Parse type value of phone numbers, email and post addresses.

Parameters

types – list of type values
supported_types – all allowed standard types

Returns

tuple of standard and custom types and pref integer

_get_types_for_vcard_object(self, object: vobject.base.ContentLine, default_type: str)¶

get list of types for phone number, email or post address

Parameters

object – vcard class object
default_type – use if the object contains no type

Returns

list of type labels

property version(self)¶

property uid(self)¶

_update_revision(self)¶

Generate a new REV field for the vCard, replace any existing

All vCards should only always have one revision, this is a requirement for version 4 but also makes sense for all other versions.

Return type: NoneType

property birthday(self)¶

Return the birthday as a datetime object or a string depending on weather it is of type text or not. If no birthday is present in the vcard None is returned.

Returns: contacts birthday or None if not available

property anniversary(self)¶

Returns: contacts anniversary or None if not available

_get_ablabel(self, item: vobject.base.ContentLine)¶

Get an ABLABEL for a specified item in the vCard. Will return the ABLABEL only if the item is part of a group with exactly two items, exactly one of which is an ABLABEL.

Parameters: item – the item to be labelled
Returns: the ABLABEL in the circumstances above or an empty string

_get_new_group(self, group_type: str = '')¶

Get an unused group name for adding new groups. Uses the form item123: or itemgroup_type123 if a grouptype is specified.

Parameters: group_type – (Optional) a string to add between “item” and the number
Returns: the name of the first unused group of the specified form

_add_labelled_object(self, obj_type: str, user_input, name_groups: bool = False, allowed_object_type: ObjectType = ObjectType.string)¶

Add an object to the VCARD. If user_input is a dict, the object will: be added to a group with an ABLABEL created from the key of the dict.

Parameters

obj_type – type of object to add to the VCARD.
user_input (str or list(str) or dict(str) or dict(list(str))) – Contents of the object to add. If a dict
name_groups – (Optional) If True, use the obj_type in the group name for labelled objects.
allowed_object_type – (Optional) set the accepted return type for vcard attribute

_prepare_birthday_value(self, date: Union[str, datetime.datetime])¶

Prepare a value to be stored in a BDAY or ANNIVERSARY attribute.

Parameters: date (datetime.datetime or str) – the date like value to be stored
Returns: the object to set as the .value for the attribute and weather it should be stored as plain text
Return type: tuple(str,bool)
