# Barkr

**Barkr**[^1] is a social media cross-posting tool written in Python: set it up and never worry about manually posting the same message to multiple channels ever again!

With **Barkr** you can setup a series of channels (e.g. social media accounts) to read messages from and / or post messages to. You can mix and match read / write modes, and add multiple accounts of the same type of channel as well without worrying that the same message will be re-posted to a channel it comes from.

Note that **Barkr** is limited to text posts only. Want to see that change? Start a discussion on a new issue!

[^1]: "Barkr" (missing "e") as in "entity that barks". See: [dogs](https://en.wikipedia.org/wiki/Dog).

## Motivation

I wrote **Barkr** for a personal use case after noting how much fragmentation there currently is (as of 2023) in the social media space, as a way to reduce the cost of engaging with multiple social media platforms, and also as a (very simple) way to practice using threads in Python.

## Installation

Use the package manager [pip](https://pip.pypa.io/en/stable/) to install `barkr`.

```bash
pip install barkr
```

## Usage

Create a Python script and specify all the channels you want to use. Channel connections are present in the [`barkr.connections`](./barkr/connections/) module.

A simple script showcasing how to set up three Mastodon connections with multiple modes that can run in the background is outlined below:

```python
from barkr.main import Barkr

from barkr.connections import (
    ConnectionMode,
    BlueskyConnection,
    DiscordConnection,
    MastodonConnection,
    RSSConnection,
    TelegramConnection,
    TwitterConnection,
)

from barkr.models import Message

barkr = Barkr(
    [
        # Barkr will read new messages posted by this account, and queue them to
        # other accounts on write mode, but will not post anything to it.
        MastodonConnection(
            "Read only connection",
            [ConnectionMode.READ],
            "<ACCESS TOKEN HERE>",
            "<INSTANCE URL HERE>",
        ),
        # Barkr will write queued messages to this account, but will not read anything
        # new posted to this account or queue anything from this account to other ones.
        DiscordConnection(
            "Write only connection",
            [ConnectionMode.WRITE],
            "<BOT TOKEN ID HERE>",
            "<CHANNEL ID HERE>",
        ),
        # Barkr will read new messages from this account to be queued onto others, and will
        # post new messages from other channels into this one as well.
        BlueskyConnection(
            "R/W connection",
            [ConnectionMode.READ, ConnectionMode.WRITE],
            "<BLUESKY HANDLE HERE>",
            "<PASSWORD / APP PASSWORD HERE>",
        ),
        # Another example using Twitter -- note that the TwitterConnection only
        # supports write-only mode through the Twitter V2 API
        TwitterConnection(
            "Write only Twitter Connection",
            [ConnectionMode.WRITE],
            "<CONSUMER KEY HERE>",
            "<CONSUMER SECRET HERE>",
            "<ACCESS KEY HERE>",
            "<ACCESS SECRET HERE>",
            "<BEARER TOKEN HERE>",
        ),
        # One more, showcasing a Telegram write-only connection
        TelegramConnection(
            "Write only Telegram connection",
            [ConnectionMode.WRITE],
            "<TELEGRAM BOT TOKEN HERE>",
            "<TELEGRAM CHAT / CHANNEL ID HERE>",
        ),
        # You can also read from an RSS feed!
        RSSConnection(
            "Read only RSS connection",
            [ConnectionMode.READ],
            "<RSS FEED URL HERE>"
        ),
    ]
)

# Blocking: will start reading and writing threads to keep the connections in sync
barkr.start()

# Non-blocking, if you only need to write messages to your connections
barkr.write_message(
    Message(
        id="123456",
        message="Hello, world!",
    )
)
```

Always keep in mind proper secret management practices when using Barkr: instead of hardcoding access tokens / cookies / user and passwords, use tools like environment variables, `dotenv` or other secret managers!
