As suggested here: SlimeKnights/TinkersConstruct#4967 (comment)
It would be nice if mods would be able to apply a container tag rather than needing to include Mouse Tweaks as a dependency. Support for Tinker's Construct is partially broken without this.

Hm, does @MouseTweaksDisableWheelTweak really require Mouse Tweaks to be loaded at runtime? I've seen a few mods use it, surely they wouldn't if it required Mouse Tweaks... That said I honestly have very little idea how to do this properly (or what a Container tag is) so maybe there's some example I could follow and some test mod with which I could test that I got it right?

I cannot see how adding an annotation to a class would not be a runtime dependency.

As far as what a container tag is, any registry in minecraft supports tags. Its just like a block tag or an item tag, but on the container registry. Find the registry closest to the container screens and use tags from that.

I cannot see how adding an annotation to a class would not be a runtime dependency.

The idea was to have an "api" type dependency with the annotation class, and at runtime Mouse Tweaks checks the annotation presence with reflection. I think a number of other mods also have "api" dependencies that don't require said mods loaded at runtime; it's entirely possible that I did something wrong though.

The mods that do that annotate a class used nowhere else in their logic (that is, that has no use without the mod the annotation is from). Not annotate a class that the mod cannot run without.

For example, JEI annotates a JEI plugin class, not my recipe class or my GUI

I am going to go ahead and bump this issue again. Adding a container tag is the best way to fix this.

Do you mind making a pull request?

It would be quite awhile before I have time to do that as I'm still focused on making my own mod stable right now.

You would accomplish it far faster as you know your codebase and where you intended that blacklist.

Container menu tags are very straight forward; you just do something like this to query the tag using the container menu instance: https://github.com/SlimeKnights/Mantle/blob/1.20/src/main/java/slimeknights/mantle/util/RegistryHelper.java#L54-L60

(would be easier if Mojang just added a method to fetch a holder given an object).

Beyond that, just make a TagKey<ContainerMenuType> (or whatever the base class is for that registry) forge has examples of other registries in their Tags class.

Do you have an example mod I could use to test that I did it right?

You should be able to just add the tag to some vanilla container, e.g. a chest. Registry name is menu, so data/mousetweaks/tags/menu/disable_wheel_tweak.json would be the location for TagKey.create(Registries.MENU, new ResourceLocation("mousetweaks", "disable_wheel_tweak")). Just make sure to fill the tag with menu IDs if you are using the menu registry for this, seems if you wanted to test with a single chest that is minecraft:generic_9x3.

You could use a different registry but I think menu is closest to a screen. If a screen has no menu, then there is not really an equivalent and you'd need a more complex API to allow disabling without a runtime time dependency.
