Nio-Bot

Making Matrix bots simple

---

Installing

You can install the latest stable release from PyPi:

pip install nio-bot
# Or for cutting-edge releases:
# pip install --pre nio-bot

You may also want some extras:

• End-to-End encryption support: nio-bot[e2ee]
• The CLI (recommended): nio-bot[cli]
• Both: nio-bot[cli,e2ee]
• Development dependencies: nio-bot[dev]

Please note that e2ee uses olm, which depends on libolm. You can likely install this though your system package manager.

Features

Nio-Bot is built on the solid client library, matrix-nio. This means that you get the full experience of a Matrix client, with the added benefit of being able to easily create bots.

Nio-Bot comes with a whole host of features to help make your development experience as easy as possible. Some features include, but are not limited to:

• A powerful commands framework (Modules, aliases, checks, easy extensibility)
• Custom argument parser support
• A flexible event system
• Simple end-to-end encryption
• Automatic markdown rendering when sending/editing messages
• Super simple to use Attachments system
• Very customisable monolithic client instance
• A simple, easy-to-use CLI tool for some on-the-go tasks
• Full attachment support (File, Image, Audio, Video), with encryption support
• In-depth, simple, clean documentation

A quick example

# This example was written using version 1.1.0.
import niobot

client = niobot.NioBot(
    # Note that all of these options other than the following are optional:
    # * homeserver
    # * user_id
    # * command_prefix
    homeserver="https://matrix.example.org",  # it is important that you use the matrix server, not the delegation URL
    user_id="@example1:example.org",
    device_id="my-device-name",
    command_prefix="!",
    case_insensitive=True,
    owner_id="@example2:example.org",
    ignore_self=True  # default is True, set to false to not ignore the bot's own messages
)

@client.on_event("ready")
async def on_ready(sync_result: niobot.SyncResponse):
    print("Logged in!")


# A simple command
@client.command()
async def ping(ctx: niobot.Context):
    latency = ctx.latency
    await ctx.respond(f"Pong! {latency:.2f}ms")


# A command with arguments
@client.command()
async def echo(ctx: niobot.Context, *, message: str):
    await ctx.respond("You said: " + message)


client.run(access_token="...")

Using the CLI to get an access token

If you install the cli extras, you can use niocli to get an access token from a username and password (read this for why you'd want to use an access token):

niocli get-access-token -U '@example1:example.org' -D 'my-device-name'

After putting in your password, an access token will be printed to the console once the login is successful.
