5555ff-lib
by Jodek
5555ff lib is a shared library that Jodek's datapacks load so that several packs can change the same vanilla loot table without overwriting one another.
What it does
When more than one datapack edits the same vanilla loot table, normally only one edit survives. The library takes over those vanilla overrides itself, so multiple packs can alter the drops of one mob, such as a head from Mob Heads and a name tag from Name Tag, and keep both results. Packs also stop cluttering their own files with duplicated overrides.
Shared code lives in the library as well: predicates such as sneak detection, plus utilities that several packs rely on. The library also acts as a hub for managing the datapacks, so players do not have to remove datapacks by hand. Packs that list 5555ff lib as a dependency work with it, and some of Jodek's packs work without it but gain extras when it is present.
Mob Heads, Bigger Stack Size, Call Your Horse, Shulkers Drop Two Shells and Bat Membrane (No Phantoms) are among the 16 mods that require it. The library is published for Fabric, Forge, NeoForge and Quilt, and as a datapack for server platforms. Only the server must run it, while clients may keep it installed for the extras.
Key features
Loot table dispatch
All vanilla loot table overrides go through the library, which lets several datapacks modify one mob's drops together.
Shared predicates
Predicates such as sneak detection are defined once in the library and reused by every pack that needs them.
Datapack management
A central interface manages the installed datapacks, so packs can be handled from one place.
Shared utilities
Reusable code that multiple packs rely on is kept in one place instead of being copied into each pack.

What the author says
5555ff lib is the shared library that powers all of my datapacks/mods. It handles cross-pack compatibility, provides a management interface and includes shared utilities. Some of my packs require this library (especially those that modify vanilla loot tables), for others it's just optional. The packs then work…
