polybot 0.9.3

A simple framework for building robust social media bots for multiple networks

Polybot

Polybot is a simple framework for building robust social media bots for multiple networks in Python.

Features

• Automatically post to X/Twitter, Mastodon, Bluesky.
• A friendly command-line setup interface to handle the authentication hassle for you.
• Automatic state persistence - just put your state in the self.state dict and it'll get saved/restored across runs.

X/Twitter support is no longer regularly tested as the authors no longer use it. Reliability can't be guaranteed but pull requests are welcome.

Limitations/Wishlist

• Polybot currently doesn't have support for receiving messages, so it's only useful for post-only bots.

Getting started

Install Polybot from PyPi using your package manager of choice.

from polybot import Bot

class HelloWorldBot(Bot):
  def main(self):
    while True:
      self.post("Hello World")
      sleep(300)

HelloWorldBot('helloworldbot').run()

To configure the accounts the bot uses, just run:

./helloworldbot.py --setup

You'll be guided through authenticating and a config file will be automatically created.

Use the --profile [name] to save and use a specific state/config.

By default, the bot will run in development mode, where it doesn't actually post to services. To run in live mode, pass the --live flag.

Images

One or more images can be attached by creating an Image object, which can be created from a path, a file object, or bytes.

from polybot import Image

self.post("Hello World",
  images=[Image(path="/path/to/image", mime_type="image/png", description="Alt text")]
)

Images are automatically resized to below the maximum allowable size on each platform.

Handling post length limitations

Services have differing post length limits, so a list of messages can be passed to the post method, and Polybot will choose the longest message which is supported by each configured service.

self.post(["This is a short message", "This is a much longer message......"])

Alternatively, the wrap argument can be used to split a message into multiple posts:

self.post("Long message...", wrap=True)

State management

Polybot provides a dictionary at self.state where your bot can store any data which needs to be persisted, to avoid repeating posts.

The state dictionary is serialised to a file called <bot_name>.state in the local directory. This automatically happens when the process is terminated, but you can also trigger this by calling self.save_state(), or by sending the process a SIGHUP signal.
