PyCord-TF

A Discord bot built to easily fetch listings for certain items and check the buy orders and sell orders as seen on backpack.tf as they progress over the last year.

Features (Stuff is bound to be removed and added)

• Automatically fetches listings from backpack.tf's websocket.
• Uses MariaDB to store the listings to a MySQL Database.
• When a request is made to an item, the bot should fetch all the listings for that item for the last year, average out the prices to a day level, create a graph to show the trend of buy orders and sell orders and send a picture of the graph to the user via DM (may change it to public chat but we'll see that when we get there)
• Automatic cleanup of data from the database to delete year-old data for efficient storage.
• More to come, I hope.

Prerequisites

• Python Version 3.10 or above is required
• Python-Poetry is used for dependancy and environment management, please see how to install it for your system at their website.
• Install MariaDB - Installation may depend on which Operating System you use.
  • I currently built and tested this project on Ubuntu, and I installed MariabDB following this tutorial.

  • For MacOS users, click here
• Create a Discord server for yourself (duh), or use the one you already own!
• Obtaining a Bot Token for Discord: Follow the instructions here to create a bot and add it to your server.

When installing the dependancies on poetry, you might encounter some errors. Try installing the following packages manually:

• sudo apt-get install libsqlite3-dev
• sudo apt-get install python3.x-dev (depends on your Python version, for example if you are using Python 3.10 then use python3.10-dev)
• sudo apt install libmariadb3 libmariadb-dev

Running the project

Once everything has been set up, this is how you run the project:

• When running the project for the first time, while in the project directory, run poetry install. This will install all the dependancies required.

• Within the same project directory, run poetry shell

• nohup python main.py & will start and run the driver program in the background. Logs of the various services can be seen within the logs/ folder under the relevant sub-folders.

• To stop the script, type ps aux | grep main.py in the terminal, you should see an output as such:

  • As visible here, my process ID is 4389. To kill the process, simply type kill <ID>, in this case it would be kill 4389.
