Datapack Error Viewer

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): DatapackErrorViewer did not start: java.lang.NoClassDefFoundError: net/minecraft/client/gui/components/FittingMultiLineTextWidget.

What it needs from Kiln

  • Mixin
  • net.fabricmc.fabric.api.resource.v1.ResourceLoader
  • net.fabricmc.fabric.api.resource.v1.pack.PackActivationType
  • net.fabricmc.loader.api.ModContainer
  • net.minecraft.client.gui.components.FittingMultiLineTextWidget
  • net.minecraft.network.chat.ComponentUtils
  • FabricLoader.getModContainer()
  • FabricLoader.isDevelopmentEnvironment()
  • Screen.height
  • Screen.width

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)
