minestrapper 0.3.5

Minestrapper is a bootstrapper for Minecraft servers that lets you easily add custom features to your server without needing a full mod/plugin loader.

Minestrapper

A bootstrapper for Minecraft Java Edition Servers

About

Rather than building full Java plugins or mods, this project lets you tap into the server’s state and other lifecycle events, and add custom functionality directly in Python.

That means small features can be added without the overhead of a mod loader (e.g. Fabric, Forge) or plugin loader (e.g. Paper, Spigot), while keeping the server in its vanilla form.

[!NOTE] Feel free to still use your favorite mods or plugins alongside it if you want! Minestrapper mainly serves for smaller, simpler features.

Current Features

• Config Handling
  • Contains a class for managing configuration files of both Minestrapper and Minecraft.
  • Minestrapper config uses a file named Config.json in a /minestrapper directory relative to the root of the Minecraft Server.
  • Allows for direct editing of server.properties.
• State Handling
  • Contains a class for getting the current state of the server based on the server output.
  • Tracks the following states: STARTING, RUNNING, PAUSED, STOPPING, STOPPED.
• New Line Callbacks
  • A lifecycle function that runs everytime a new line is sent from the Minecraft Server process
• Logger
  • Prints out stuff both from forwarding logs from the Minecraft process and also custom logs from Minestrapper.
  • Keeps Minestrapper specific logs visually consistent with Minecraft Server logs (e.g. "[19:48:06] [Minestrapper/INFO]: Initialized Minestrapper Logger successfully")
  • Logs to a file named latest-minestrapper.log and then replaces the vanilla latest.log with it when the server stops.
  • Provides transformers to modify each logged line to the output as needed.
• Built-in features:
  • "State Styles"
    • Updates the terminal title and text color based on the server's current state.
    • Makes it easier to see whether the server is starting, running, paused, stopping, or stopped.
  • "Server Resource Pack"
    • Includes a lightweight HTTP server for serving a server resource pack.
    • Removes the need for an external hosting site for the pack.
    • Keeps resource pack delivery self-contained within the server setup.

Potential Future Features

• Backups: Let the owner integrate save backups everytime the server closes locally. It can either be done locally only, with cloud services, or even both.
• Remote Panels: Allow the owner along with anyone else authorized to remotely turn on and off the server. Only the owner will be able to view logs and run commands however.
• Custom Commands: Add your own admin commands that can trigger multiple Minecraft commands or even run Python code.

Installation Guide

1. Install Python at https://www.python.org/ (>=3.1).
2. Go to your Minecraft Server directory.
3. Make a directory exactly named minestrapper and change directory to it.

mkdir minestrapper && cd minestrapper

4. Make a new Python environment.

Windows:

python -m venv .venv

MacOS / Linux:

python3 -m venv .venv

5. Activate the environment.

Windows:

.\.venv\Scripts\activate

MacOS / Linux:

source .venv/bin/activate

6. Install the minestrapper package.

pip install minestrapper

7. Create a file exactly named Config.json and edit to your liking.

{
  "$schema": "https://faizaan-j.github.io/mine-strapper/schemas/Config.schema.json"
}

[!NOTE] The schema will help you fill out the file so it's recommended to use some kind of app that can read JSON schemas to edit the file easier. There are numerous required fields that you must fill out.

8. Make an entry point file inside the minestrapper directory.

Example:

from pathlib import Path

from minestrapper import Server

if __name__ == "__main__":
    server = Server(path=Path.cwd().parent)
    server.start_server()

    server.wait_loop()

Important Notes

• You still need to do any necessary port forwarding yourself.
• Minestrapper has only been tested on modern versions of Minecraft. However, the estimated minimum version that this should work is Java Edition 1.7.2
