About this project
What does Modder Name Lib add?
Modder Name Lib is my personal library of code shared between all Season 2 projects.
You probably do not need to install Modder Name Lib separately. Modder Name Lib is included in all mods that use it using the "jar-in-jar" systems in Fabric and NeoForge. If you choose to manually install it, the version you select will (probably?) be used instead of the bundled versions.
At the moment, it contains:
- basic mod scaffolding and abstractions over the differences between modloaders,
- a custom system for registering content and datagenning stuff at the same time,
- an error-reporting system,
- a configuration library, usable through both fabric and neoforge, with a custom config format on Fabric
And it will grow to contain anything else I need.
what is "Season 2"
All Season 2 mods are developed and tested together, in the same Git repo, compiled from the same codebase.
During Season 1 (2018-2025), I developed all my mods separately. This made it difficult to start new projects, annoying to port projects between Minecraft versions, error-prone to maintain code shared between multiple projects, and switching between projects sometimes required long waiting periods as the development tooling got its act together. This factors combined caused me to burn out of Minecraft modding.
During Season 2 (2025-?), I aim to address these problems with new development tooling.
One such tool is this library, which holds all the duplicated code and helps me hit the ground running when I choose to port to a new version of Minecraft.
what's in a name?
A moddernamelib is a derisive term for "library mods only intended to be used by one modder." I have become the thing I sought to destroy.
