Who has Mending?

A client-side utility mod that visualizes villager trades (only enchanted books) as nameplates above their heads. No more signs, no more manual naming, and no more forgetting "Who has Mending?".

Key Features

• Auto-Detection: Automatically records trade information just by opening the trade screen.
• Virtual Nameplates: Displays what matters most (e.g., [10]Mending) directly above the villager's head.
• Smart Filtering:
  • First Book Only: Only displays the first (topmost) enchanted book in the trade list.
  • Enchanted Books Only: Ignores junk trades like paper or glass.
  • Librarians Only: Only tracks Librarians, ignoring farmers or clerics.
  • Empty Trade Hiding: If a Librarian has no enchanted books, no nameplate is shown.
• Data Persistence: Trade data is saved per world/server. Your records won't disappear!
• Customizable: Toggle display with a keybind (Default: Unbound, set it in Controls).

Installation

1. Install Fabric Loader.
2. Install Fabric API.
3. Download whohasmending-MCversion-x.x.x.jar and place it in your mods folder.

How to Use

1. Find a Librarian: Right-click to open their trade window.
2. Done!: Close the window. The mod has already recorded the enchanted books.

Controls

• Toggle Display: Default is Unbound. Go to Options > Controls > Key Binds > Miscellaneous > Toggle Villager Trade Display to assign a key (e.g., 'H').
