Attributes#

- class slidge.BaseGateway#
Must be subclassed by a legacy module to set up various aspects of the XMPP component behaviour, such as its display name or its registration process.
On slidge launch, a singleton is instantiated, and it will be made available to public classes such
LegacyContact
orBaseSession
as the.xmpp
attribute. Since it inherits fromslixmpp.componentxmpp.ComponentXMPP
, this gives you a hand on low-level XMPP interactions via slixmpp plugins, e.g.:self.send_presence( pfrom="somebody@component.example.com", pto="someonwelse@anotherexample.com", )
However, you should not need to do so often since the classes of the plugin API provides higher level abstractions around most commonly needed use-cases, such as sending messages, or displaying a custom status.
- REGISTRATION_FIELDS: Collection[slidge.command.base.FormField]#
Iterable of fields presented to the gateway user when registering using XEP-0077 extended by XEP-0004.
- REGISTRATION_INSTRUCTIONS: str = 'Enter your credentials'#
The text presented to a user that wants to register (or modify) their legacy account configuration.
- REGISTRATION_TYPE#
This attribute determines how users to register to the gateway, ie, how they login to the legacy service. The credentials are then stored persistently, so this process should happen once per user (unless they unregister).
The registration process always start with a basic data form (XEP-0004) presented to the user, which is send But the legacy login flow might require something more sophisticated, such as a
SINGLE_STEP_FORM: 1 step, 1 form, compatible with XEP-0077 (in-band registration).
QRCODE: The registration requires flashing a QR code in an official client. See
send_qr()
,get_qr_text()
andconfirm_qr()
.TWO_FACTOR_CODE: The registration requires confirming login with a 2FA code, eg something received by email or SMS. See
validate_two_factor_code()
.
- COMPONENT_TYPE: str | None = ''#
Type of the gateway, should ideally follow https://xmpp.org/registrar/disco-categories.html
- COMPONENT_AVATAR: slidge.util.types.AvatarType | None#
Path, bytes or URL used by the component as an avatar.
- ROSTER_GROUP: str = 'slidge'#
Roster entries added by the plugin in the user’s roster will be part of the group specified here.
- SEARCH_FIELDS: Sequence[slidge.command.base.FormField]#
Fields used for searching items via the component, through XEP-0055 (jabber search). A common use case is to allow users to search for legacy contacts by something else than their usernames, eg their phone number.
Plugins should implement search by overriding
BaseSession.search()
, effectively restricting search to registered users by default.If there is only one field, it can also be used via the
jabber:iq:gateway
protocol described in XEP-0100. Limitation: this only works if the search request returns one result item, and if this item has a ‘jid’ var.
- WELCOME_MESSAGE = "Thank you for registering. Type 'help' to list the available commands, or just start messaging away!"#
A welcome message displayed to users on registration. This is useful notably for clients that don’t consider component JIDs as a valid recipient in their UI, yet still open a functional chat window on incoming messages from components.
- MARK_ALL_MESSAGES = False#
Set this to True for legacy networks that expects read marks for all messages and not just the latest one that was read (as most XMPP clients will only send a read mark for the latest msg).
- PROPER_RECEIPTS = False#
Set this to True if the legacy service provides a real equivalent of message delivery receipts (XEP-0184), meaning that there is an event thrown when the actual device of a contact receives a message. Make sure to call Contact.received() adequately if this is set to True.
- async validate(user_jid, registration_form)#

Convert a legacy msg ID to a valid XMPP msg ID. Needed for read marks and message corrections.
The default implementation just converts the legacy ID to a

- Returns:
Should return a string that is usable as an XMPP stanza ID

- abstract async login()#
Login the gateway user to the legacy network.
Triggered when the gateway start and on user registration. It is recommended that this function returns once the user is logged in, so if you need to await forever (for instance to listen to incoming events), it’s a good idea to wrap your listener in an asyncio.Task.
