A JupyterLab extension for **hot patching** notebooks that are edited externally, for example by an AI coding agent like Claude Code.

Instead of triggering a full notebook reload (which restarts the kernel and clears widget state), only the cells that actually changed are patched into the live notebook model.

https://github.com/user-attachments/assets/6e287a55-41ff-48c0-a48c-f7a56d708413

## What it does

```
Claude Code edits notebook.ipynb on disk
          ↓
Extension detects the file change
          ↓
Only modified cells are patched
          ↓
Kernel keeps running · Widget state intact · Scroll position preserved
```

## Installation

Requires JupyterLab 4.

```bash
pip install hot-notebook-patching
```

Then restart JupyterLab (or start it fresh) — the extension is prebuilt, no `jupyter labextension build` step needed.

To uninstall:

```bash
pip uninstall hot-notebook-patching
```

## Usage

### Toolbar button

Each notebook gets a ⚡ bolt button in the toolbar. Click it to toggle **auto-patch mode** — the extension will watch the file for changes and patch automatically.

### Commands

| Action | How |
|---|---|
| Patch once from disk | Toolbar ⚡ button (when auto-patch is off) · `Cmd/Ctrl+Alt+P` inside a notebook · Command Palette → *Patch Notebook From Disk* |
| Toggle auto-patch | Toolbar ⚡ button · Command Palette → *Toggle Auto-Patch on File Change* |

### What is preserved

- Running kernel
- Widget state (ipywidgets, anywidget, …)
- Cell outputs and execution counts
- Scroll position

### What is updated

- Cell source code (with line-level diff indicators)
- Cell metadata
- Added / deleted / reordered cells

## Development

```bash
# Terminal 1: rebuild on every source change
source .venv/bin/activate
jlpm watch

# Terminal 2: start JupyterLab
source .venv/bin/activate
jupyter lab
```

After each rebuild, hard-refresh the browser tab (`Cmd+Shift+R`) — no server restart needed.
