Adopt the simplexmq names rework (PR #7045): name resolution is now owned by the agent (resolveSimplexName picks a names-role server), so the chat-side iteration is removed - delete ResolveError, iterateResolvers, resolveOnUserServers, enabledSMPServersForUser and resolveErrorToChatError. One error type: resolver/agent failures flow through ChatErrorAgent; remove the CEvtSimplexName* events, SimplexNameVerifyFailReason, SimplexNameConflictEntity and CESimplexNameResolverUnavailable. APIVerifySimplexName returns CRSimplexNameVerified (verified::Bool), mirroring CRConnectionVerified. connectPlan handles the name target directly; updateProfile WithConflict aliases collapsed into the plain functions. Add the per-operator "names" SMP server role (migration 20260612_smp_role_names, official operator on by default) feeding ServerRoles.names -> UserServers.nameSrvs. Bump simplexmq pin to ce69adfd and regenerate sha256map.nix.
SimpleX Chat Python library
Python 3.11+ client for SimpleX Chat bots. Equivalent to the Node.js library.
Install
pip install simplex-chat
The native libsimplex is downloaded lazily on first use. To pre-fetch:
python -m simplex_chat install # sqlite (default)
python -m simplex_chat install --backend postgres # linux-x86_64 only
Quick start
import re
from simplex_chat import Bot, BotProfile, Message, SqliteDb, TextMessage
bot = Bot(
profile=BotProfile(display_name="Squaring bot"),
db=SqliteDb(file_prefix="./squaring_bot"),
welcome="Send me a number, I'll square it.",
)
@bot.on_message(content_type="text", text=re.compile(r"^-?\d+(\.\d+)?$"))
async def square(msg: TextMessage) -> None:
n = float(msg.text or "0")
await msg.reply(f"{n} * {n} = {n * n}")
@bot.on_message(content_type="text")
async def fallback(msg: Message) -> None:
await msg.reply("Send me a number, like 7 or 3.14.")
if __name__ == "__main__":
bot.run()
bot.run() blocks. The connection address is logged on startup — paste it into a SimpleX client to talk to the bot. Ctrl+C to stop.
Three decorators: @bot.on_message(...), @bot.on_command(name), @bot.on_event(tag). Message handlers are first-match-wins in registration order, so register specific filters first and catch-alls last.
See examples/squaring_bot.py for the full example.
Development
uv venv && source .venv/bin/activate
uv pip install -e '.[dev]'
ruff check && pyright && pytest tests/
Wire types under src/simplex_chat/types/_*.py are generated. Regenerate with cabal test simplex-chat-test --test-options='--match Python'.
Release
Manual for now. Bump _version.py:__version__, build a wheel, upload to PyPI:
uv build --wheel
uv publish --token "$PYPI_TOKEN"
