Just Enough Markers (JEM)

Just Enough Markers (JEM)

Enhance JEI with visual markers for modified recipes.

Just Enough Markers (JEM) is a lightweight NeoForge mod that helps modpack creators and technical players quickly identify recipe changes made by KubeJS or other modifications.

🌟 Key Features

• Highlight recipe changes: Added, removed, or altered recipes are clearly marked in JEI.
• Recipe filtering:
  
  • Recipes with IDs matching your filter (recipeIdFilter) are automatically highlighted.
  • Recipes without IDs can be highlighted based on their outputs (outputFilter).
• Customizable markers:
  
  • Per-category marker positions (categories).
  • Adjustable X/Y offsets.
  • Tooltips with configurable messages (2 lines by default).
• Debug mode: Force all recipes to display markers, useful for testing and modpack development.
• Lightweight & client-side only: Does not alter recipes, only enhances JEI’s display.

⚙️ How It Works

1. At startup, JEM checks recipes for their ID.
2. If the ID contains the recipeIdFilter, a marker is displayed.
3. Recipes without an ID are compared against the outputFilter list.
4. Markers can be positioned per recipe category with custom offsets.
5. Tooltips show your configured text when hovering over a marker.
6. Debug mode (onlySpecificRecipeID) can override filters to display markers on all recipes.
