Developer's Dream

Everything can be found on the Fabric repository's wiki: Home · ChromaKey81/devsdream-fabric Wiki (github.com)

THE FIRST RELEASE IS HERE! HOORAY!

It's available for both Forge and Fabric on 1.17.1. It adds NBT recipe types and a bunch of new, useful commands.

-added `crafting_shaped_nbt`, `crafting_shapeless_nbt`, `stonecutting_nbt`, and `smithing_nbt` under the devsdream namespace. these allow you to apply an nbt tag to the output item. the smithing recipe type even allows you tight control over conflicts between tags on the base item and tags on the output

-added `/damage`, an execute-style command that allows for nuanced damaging with many different flags and even control over the death message

-added `/dreameffect`, a version of vanilla's `/effect` that allows you to control whether the instance is ambient and whether its icon should be hidden

-added `/dreamexecute store player`, which allows you to store the execute result in many different player values, like `health`, `air`, `motion`, and even a data-style `item`

-added many new commands to modify normally unmodifiable player values, including `/motion`, `/health`, `/exhaust`, `/feed`, and `/air`

-added `/freeze` and `/ignite` to apply those effects to players

-added `/damageitem`, which allows you to damage an item in a way that automatically breaks it at 0 durability and obeys the Unbreaking enchantment

-added `/calculate` to readably run an operation on integer values or the results of commands without going through scoreboards

-added `/rng`. yay!

There's also a release available for Forge, if you want that.
