How to Use

1. Place on a Storage Block

   • Attach the NBT Export Bus to a chest, drawer, or any block with item inventory.

2. Open Configuration GUI

   • Right-click the part to configure its filter and behavior.
   • GUI allows you to:
     • Set read/write permissions
     • Toggle extract filters
     • Configure NBT match expressions

3. Write NBT Filter

   • Use the text area to enter NBT match expressions.
   • Examples:
     • {Enchantments:[{id:"minecraft:sharpness"}]} - matches only items with Sharpness enchant.
     • {display:{Name:My Sword}} - matches items with tag display value set to Name: My Sword
     • {*:"value"} - matches if any NBT value is "value"
     • {key:!"value"} - matches if the NBT named key value is not "value"
   • Supports logical expressions like &&, ||, !, nand, etc.

4. Load NBT from Item (Optional)

   • Place an item in the fake slot and press the Load button.
   • Automatically imports the item's NBT into the filter.

Matching System

NBT expressions use a custom parser that supports:

• Wildcard keys/values: "*"
• AND/OR/NAND/XOR logic
• Recursive key matching
• Negation with !value

If an item matches the expression, it's exported.
