DataTweaks
by catcoll456
DataTweaks is a Fabric utility that gives datapack creators helper commands and tweaks for building, testing and maintaining datapacks.
What it does
Developers who write datapacks can use DataTweaks to add commands that simplify testing, building and upkeep of their packs. The mod is aimed at datapack creators, and it backports a datapack-creation command so that it also works on the game versions it supports. It is server-side only, so the server runs it and players join without installing anything.
Datapacks made or edited with DataTweaks are intended to keep working in unmodded vanilla Minecraft, because the mod does not change how datapacks function on the vanilla side. Files are published for Fabric only, across four game versions: 1.21.2, 1.21.3, 1.21.4 and 1.21.5, with 1.0.0 for 1.21.5 as the latest file on the beta channel. The mod is released under All rights reserved and is not open source.
Key features
Datapack creation command
A command backports datapack creation to the versions covered by the mod's files.
Developer-oriented tweaks
Tweaks are chosen to match what datapack developers need during day-to-day work.
Testing and maintenance tools
Helper commands make testing, building and maintaining datapacks quicker to carry out.
Vanilla-compatible output
Datapacks edited with the mod are meant to run in unmodded vanilla without changes to their behavior.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Building a datapack
A creator can use the helper tools while assembling a new pack, then ship it to players who have no mod installed.
Maintaining an existing pack
Updating an older datapack with the mod's commands can make routine upkeep less time-consuming.
Who it’s for: Datapack developers who want helper commands for building and testing, and server owners who run datapacks and want the tools on the server side.
