aiosignald

Signald python bindings

Interact with the signal messaging network in python with sweet, sweet autocompletion.

Most of the code is generated by the generate.py script that uses the schema available at https://signald.org/protocol.json.

No 3rd party dep, just the python standard lib.

Install

pip install aiosignald

Have signald running. See their docs about it.

Issue tracker: https://todo.sr.ht/~nicoco/aiosignald

Part of the slidge project (but can be used independently)

Usage

Example: echo bot

import asyncio

from aiosignald import SignaldAPI
import aiosignald.generated as api

class EchoBot(SignaldAPI):
    async def handle_IncomingMessage(self, msg: api.IncomingMessagev1, _payload):
        # hook to the incoming event by naming you function handle_EventName
        # most stuff comes through an IncomingMessage anyway
        print("Received: ", msg)
        if (data_msg := msg.data_message) and (body := data_msg.body):
            await self.send(
                username=PHONE_NUMBER,
                recipientAddress=msg.source,
                messageBody=body
            )

async def main():
    loop = asyncio.get_running_loop()
    _, signald = await loop.create_unix_connection(
        EchoBot, path=SIGNALD_SOCKET_PATH)
    if ACCOUNT_TYPE == "primary":
        await signald.register(account=PHONE_NUMBER)
        # Some async code to get the SMS code
        code = await user_input("Enter your sms code?")
        await signald.verify(account=PHONE_NUMBER, code=code)
    else:
        # linking to an existing account is also possible
        resp = await signald.generate_linking_uri()
        print("Make this a QR code and scan it on your primary signal device:", resp.uri)
        await signald.finish_link(device_name="friendly-device-name", session_id=resp.session_id)
    await signald.on_con_lost

# See https://signald.org/articles/protocol/ for more info about this
SIGNALD_SOCKET_PATH = "/var/run/signald/signald.sock"
PHONE_NUMBER = "+XXXXXX"
ACCOUNT_TYPE = "primary"

asyncio.run(main())
