CITX (CIT Extension)

A mod that allows easy renaming of CIT items with a custom command.

CITX (CIT Extension)

A smart mod that makes renaming CIT items quick and easy with one command.
Made for builders, creators, and anyone tired of the anvil clanking.

👉 Features

  • Rename items with simple commands
  • Swap CIT extensions instead of stacking them
  • Full rename support for display names
  • One-command reset to default
  • Smart logics, clean-ups, and naming conditions
  • Client-side only, nothing to install server-side

🚀 Quick Reference

Command Alias What it does
/citx <input> Shortcut. Skips "extend" entirely, just adds/swaps the extension
/citx extend <extension> /citx e <extension> Adds or swaps a CIT extension, keeps the base name
/citx rename <name> /citx r <name> Replaces the entire display name
/citx reset /citx x Clears the custom name

⚠️ Important: After using any command, open and close your inventory to refresh the renamed item so it displays correctly in the world.

Unfortunately, this cannot be fixed, as it is a limitation of how Minecraft handles item renames and client-side item updates.

#️⃣ Commands

🟢 /citx extend | Adds or swaps an extension Keeps the item's base name and only touches the extension. 
/citx extend <extension>
/citx e <extension>          # alias
/citx <input>            # shortcut, no subcommand needed
For quick extension changes you don't even need to type "extend" or "e". Just `/citx <input>` on its own works the same way: 
/citx red
Grass Block → Grass Block_red
Example (full form)
/citx extend red
Grass Block → Grass Block_red
Run it again with a new extension and it replaces the old one, it doesn't stack:
Grass Block_old
/citx e new
→ Grass Block_new        ✅
→ Grass Block_old_new    ❌ (never happens)
🟡 /citx rename| Replaces the whole name 
/citx rename <name>
/citx r <name>            # alias
Example
/citx rename Mystic Sword
→ Mystic Sword
🔴 /citx reset | Resets item name back to default 
/citx reset
/citx x                   # alias

🧹 Automatic Cleanup

You don't have to think about formatting. CITX handles it in the background:

  • Collapses duplicate underscores
  • Keeps only one extension at a time
  • Adds a missing leading underscore
  • Blocks malformed names before they happen
Stone__red → Stone_red

🔁 Example Workflow

Hold: Grass Block

/citx blue           → Grass Block_blue     (shortcut for extend)
/citx green          → Grass Block_green    (swapped, not stacked)
/citx r Emerald Trophy   → Emerald Trophy
/citx x              → Grass Block          (back to default)
