Redstone Computer Utilities
by NKID00
Redstone Computer Utilities gives Fabric servers a Python library and debugging tools for redstone computers built from in-game circuits.
What it does
Redstone Computer Utilities is a lightweight modular set of debugging tools for redstone computers. It extends them with JSON and TCP debug support, so a program can exchange data with an external process. A Python library is included to simplify development, and it uses asynchronous network communication with high-level APIs and a user-friendly command line interface, with static typing throughout.
The mod is server-side only, so players join a server without installing anything, though the server itself must run it. It is compatible with vanilla clients. To use its Python library, a developer needs Python 3.7.2 or later, running CPython or PyPy. The mod is published for Fabric only, for game versions 1.16 – 1.19.3 across 15 release versions, and it needs Java 17 and the latest Fabric Loader and Fabric API. The code is open source under the Mozilla Public License 2.0, and the latest Fabric file, 0.2.1-mc1.19.3, dates from 2023-02-19.
