LemmyLink Bot

LemmyLink is a cross-platform bridge bot that connects Reddit and specific Lemmy communities. When a user triggers the bot on Reddit by including the phrase "LemmyLink!" in a comment, the bot creates a corresponding post on your Lemmy instance and replies on Reddit with the link to that post.

Features

• Reddit Trigger: Listens for the "LemmyLink!" phrase in Reddit comments.
• Lemmy Post Creation: Automatically creates a corresponding post on a Lemmy instance e.g. https://lemmy.world/c/lemmylink
• Mapping Database: Maintains SQLite-based mappings for both posts and comments to avoid duplicate syncing.
• Bidirectional Comment Sync: WORK IN PROGRESS: Synchronizes new comments between Reddit and Lemmy (for now, as top-level comments).

If you implement this, PLEASE MARK YOUR ACCOUNT AS A BOT ACCOUNT IN LEMMY!

Installation

1. Clone the Repository:

   git clone https://github.com/ateames/LemmyLink.git
   cd lemmylink_bot
   

2. Install Dependencies:

   pip install -r requirements.txt
   

3. Configuration: Update the config.py file with your credentials and settings. For example:

    # Reddit credentials (get these from https://www.reddit.com/prefs/apps)
    REDDIT_CLIENT_ID = "YOUR_CLIENT_ID"
    REDDIT_CLIENT_SECRET = "YOUR_CLIENT_SECRET"
    REDDIT_USERNAME = "YOUR_BOT_USERNAME"
    REDDIT_PASSWORD = "YOUR_BOT_PASSWORD"
    REDDIT_USER_AGENT = "LemmyLinkBot/0.1 by /u/YOUR_BOT_USERNAME"
    SUBREDDIT_NAME = "YOUR_SUBREDDIT_NAME"
   
    # Lemmy credentials and instance settings
    LEMMY_BASE_URL = "https://your-lemmy-instance.example"
    LEMMY_USERNAME = "your_lemmy_bot_username"
    LEMMY_PASSWORD = "your_lemmy_bot_password"
    LEMMY_COMMUNITY_ID = 1  # The community ID where posts will be created
   

4. Database Setup: The project uses SQLite for storing mappings between Reddit and Lemmy content. Run these commands once to create the required tables:

   python mapping_db.py
   python comment_mapping_db.py

This will create a mapping.db file in your project directory with the necessary tables.

Running the Bot

There are two main components:

1. Trigger Listener: Run main.py to start the Reddit listener that detects the "LemmyLink!" trigger, creates a corresponding Lemmy post, and replies on Reddit:

   python main.py
   

2. Bidirectional Comment Sync: Run bidirectional_sync.py in a separate terminal (or as a background process) to synchronize comments between Reddit and Lemmy:

   python bidirectional_sync.py
