The default implementation just converts the legacy ID to a str, but this should be overridden in case some characters needs to be escaped, or to add some additional, legacy network <Legacy Network>-specific logic.

The default implementation is an identity function.

Parameters:: i (str) – The XMPP stanza ID
Returns:: An ID that can be used to identify a message on the legacy network
Return type:: int

async __login_task()[source]¶

async login()[source]¶

Logs in 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.

Returns:: Optionally, a text to use as the gateway status, e.g., “Connected as ‘dude@legacy.network’”
Return type:: None

async logout()[source]¶

Logs out the gateway user from the legacy network.

Called on gateway shutdown.

Return type:: None

async on_composing(c, thread=None)[source]¶

Triggered when the user starts typing in a legacy chat (XEP-0085)

Parameters:

chat – See BaseSession.on_text()
thread
c (Recipient)

Return type:

None

async on_text(chat, text, **_kwargs)[source]¶

Triggered when the user sends a text message from XMPP to a bridged entity, e.g. to translated_user_name@slidge.example.com, or translated_group_name@slidge.example.com

Override this and implement sending a message to the legacy network in this method.

Parameters:

text (str) – Content of the message
chat (Recipient) – Recipient of the message. LegacyContact instance for 1:1 chat, MUC instance for groups.
reply_to_msg_id – A legacy message ID if the message references (quotes) another message (XEP-0461)
reply_to_fallback_text – Content of the quoted text. Not necessarily set by XMPP clients
reply_to – Author of the quoted message. LegacyContact instance for 1:1 chat, LegacyParticipant instance for groups. If None, should be interpreted as a self-reply if reply_to_msg_id is not None.
link_previews – A list of sender-generated link previews. At the time of writing, only Cheogram supports it.
mentions – (only for groups) A list of Contacts mentioned by their nicknames.
thread

Returns:

An ID of some sort that can be used later to ack and mark the message as read by the user

Return type:

int

async on_file(chat, url, **_kwargs)[source]¶

Triggered when the user sends a file using HTTP Upload (XEP-0363)

Parameters:

url (str) – URL of the file
chat (Recipient) – See BaseSession.on_text()
http_response – The HTTP GET response object on the URL
reply_to_msg_id – See BaseSession.on_text()
reply_to_fallback_text – See BaseSession.on_text()
reply_to – See BaseSession.on_text()
thread

Returns:

An ID of some sort that can be used later to ack and mark the message as read by the user

Return type:

int

async on_react(chat, legacy_msg_id, emojis, thread=None)[source]¶

Triggered when the user sends message reactions (XEP-0444).

Parameters:

chat (Recipient) – See BaseSession.on_text()
thread
legacy_msg_id (int) – ID of the message the user reacts to
emojis (list[str]) – Unicode characters representing reactions to the message legacy_msg_id. An empty string means “no reaction”, ie, remove all reactions if any were present before

Return type:

None

async on_correct(*args, **kwargs)[source]¶

Triggered when the user corrects a message using XEP-0308

This is only possible if a valid legacy_msg_id was returned by on_text().

Parameters:

chat – See BaseSession.on_text()
text – The new text
legacy_msg_id – Identifier of the edited message
thread
link_previews –
A list of sender-generated link previews. At the time of writing, only Cheogram supports it.

None

async on_displayed(c, legacy_msg_id, thread=None)[source]¶

Triggered when the user reads a message in a legacy chat. (XEP-0333)

This is only possible if a valid legacy_msg_id was passed when transmitting a message from a legacy chat to the user, eg in slidge.contact.LegacyContact.send_text() or slidge.group.LegacyParticipant.send_text().

Parameters:

chat – See BaseSession.on_text()
legacy_msg_id (int) – Identifier of the message/
thread
c (Recipient)

Return type:

None

async on_search(form_values)[source]¶

Returns:

async on_avatar(bytes_, hash_, type_, width, height)[source]¶

Triggered when the user uses modifies their avatar via XEP-0084.

Parameters:

type – The MIME type of the avatar.
width – The width of the avatar image.
