Description
Config Editor
Edit your mod config files without ever leaving the game.
Config Editor is a Fabric client-side mod that gives you a full-featured text editor, a visual JSON editor, an AI assistant, and a block info overlay — all accessible with a keybind while you play.
Features
📝 In-Game Config Editor
Open any config file from your .minecraft/config folder directly inside the game. No more alt-tabbing to Notepad or VS Code.
- Syntax highlighting for JSON, TOML, YAML, Properties, CFG, and plain text
- Line numbers, horizontal and vertical scrollbars
- Find & Replace (Ctrl+F) with previous/next navigation
- Auto-save with file locking — retries up to 3 times if the file is busy
- Unsaved-changes warning when you try to close
- Backup button to snapshot your entire config directory before editing
- Open Folder button to reveal the config directory in your file manager
- Dark / Light / Auto theme with a toggle button
🖱️ Visual JSON Editor
Switch to a point-and-click interface for JSON files. No need to remember syntax.
- Add, rename, delete, and reorder fields
- Change value types (String / Number / Boolean / Null / Object) with one click
- Nested object support with expand/collapse
- Scroll through large files with up/down buttons
🤖 AI Chat Assistant (requires Ollama)
Ask an AI about your config files without leaving the game.
- Loads a file or entire folder into the conversation with one click
- Uses a local Ollama server (default:
localhost:11434, model:tinyllama) - Server availability check on open — shows a clear offline message if Ollama is not running
- Scrollable chat history
� Block Info Overlay
A Jade/WTHIT-style HUD element shown at the top of the screen while you play.
- Displays the block name and registry ID (e.g.
minecraft:stone) of whatever your crosshair is pointing at - Shows the block's item icon next to the name
- Semi-transparent background with a clean border
- Only visible in-game — disappears when any screen is open
- Fully toggleable via the config file (
show_block_overlay)
📦 NBT Viewer
Point your crosshair at a block entity or entity and press the NBT key to open a viewer showing its NBT data as formatted JSON. Save it to saved_nbt/ with a custom filename.
🔌 Plugin API
Other mods can extend the editor by implementing the ApiEntrypoint interface. Built-in plugins include:
| Plugin | What it does |
|---|---|
| Undo/Redo | Tracks edit history |
| Text Stats | Shows character, word, and line count |
| Date/Time Display | Shows the current time in the editor toolbar |
| Auto Bracket Completion | Automatically closes (, [, {, " |
Manage which plugins are active from the Plugins button inside the editor.
⚡ Performance Optimisations
- GC hint on world join/leave — triggers a garbage collection pass before the new world starts allocating memory, reducing the RAM spike that causes join-world lag. Frees hundreds of MB in practice.
- Particle clear on level set — drops stale particle objects from the old world before the new one loads.
- Config is read from disk at most once every 2 seconds, not on every frame or keystroke.
Installation
- Install Fabric Loader and Fabric API
- Drop
config_editor-*.jarinto yourmods/folder - Launch the game
Requirements:
- Minecraft
26.1 - Fabric Loader
≥ 0.18.2 - Fabric API
- Java
≥ 21
The AI Chat feature additionally requires Ollama running locally with a model pulled (e.g. ollama pull tinyllama).

| Open Editor | Opens the config file editor |
| Open AI Chat | Opens the AI chat assistant |

For Mod Developers — Plugin API
You can add custom behaviour to the editor by implementing ApiEntrypoint and registering it via the Fabric entrypoint system in your fabric.mod.json:
"entrypoints": {
"config_editor": [
"com.example.yourmod.YourEditorPlugin"
]
}
public class YourEditorPlugin implements ApiEntrypoint {
@Override
public void init() { }
@Override
public void renderButton(GuiGraphicsExtractor context, int mouseX, int mouseY, float delta) {
// Draw custom HUD elements over the editor
}
@Override
public InteractionResult onType(int keyCode, int scanCode, int modifiers) {
// Intercept keystrokes — return FAIL to consume the event
return InteractionResult.PASS;
}
}
