Thaumonomicon To JEI

A Forge mod for Minecraft 1.12.2 that adds a JEI button on the recipe pages of the Thaumonomicon (Thaumcraft 6): one click and JEI opens showing the currently displayed recipe's output.

Downloads

Features

• A small JEI button appears at the bottom-right of any recipe page in the Thaumonomicon
• Clicking it opens JEI on the output of the recipe being viewed
• Works for all recipe types displayed by the Thaumonomicon:
  • Arcane workbench (thaumaturgy) recipes
  • Crucible recipes
  • Infusion recipes (when the output is a concrete item)
  • Vanilla crafting recipes
• Hovering the button shows the recipe output's name
• Client-side only

Requirements

• Forge 14.23.5.2860 (Minecraft 1.12.2)
• JEI 4.16.x
• Thaumcraft 6.1.BETA26 (and its dependency Baubles)

How It Works

• Unlike the FML KeyInputEvent (which never fires while a GuiScreen is open), this mod hooks Forge's GuiScreenEvent.DrawScreenEvent.Post to draw the button and GuiScreenEvent.MouseInputEvent.Pre to detect the click while the Thaumonomicon is open.
• The currently shown recipe is read from GuiResearchPage.shownRecipe (via a small, contained reflection call), then resolved through the same chain Thaumcraft uses internally: CommonInternals.getCatalogRecipe → getCatalogRecipeFake → CraftingManager.getRecipe → ConfigRecipes.recipeGroups.
• Resolving the output follows Thaumcraft's own addRecipesToList logic (BluePrint, CrucibleRecipe, InfusionRecipe, IRecipe).
• JEI is opened through the mod's own @JEIPlugin (onRuntimeAvailable caches the IJeiRuntime), using createFocus(IFocus.Mode.OUTPUT, stack) + getRecipesGui().show(focus).

Known Limitations

• Infusion recipes whose output is not a concrete item (e.g. enchantment-based recipes) show no button — they cannot be represented as a single JEI ingredient.
• Multiblock plans (BluePrint) with no display block show no button.
• When a research key groups several sub-recipes, the first resolvable output is used.
