jupyter-next

Open and edit Jupyter notebooks. Interactive computing with kernel management and rich output rendering.

Features

• Notebook editing: Open and edit .ipynb files with cell-based interface.
• Execute cells: Run code with real-time output display and a live execution timer while running.
• Markdown support: Live preview for markdown cells, rendered whenever the notebook is in command mode.
• Multiple kernels: Python, Julia, R, and other Jupyter kernels.
• Rich output: Images, HTML, LaTeX, Plotly, Vega, and interactive plots.
• Cell operations: Insert, delete, move, merge, and split cells.
• Cell hover actions: Run, clear output, and delete buttons appear on cell hover and act on that specific cell without changing the active cell.
• Cell type selector: Switch active cell type via the toolbar dropdown or mouse wheel scroll over the selector.
• Multi-select cells: Ctrl+click to toggle, Shift+click for range selection, Shift+Up/Down to grow the selection from an anchor cell.
• Drag & drop: Reorder cells by dragging with auto-scroll near edges. Selection and active cell are preserved across the move.
• Undo/redo: Full cell operation history with keyboard shortcuts.
• Dual mode: Command mode for navigation, edit mode for typing (like Jupyter).
• Jupyter keybindings: Familiar shortcuts like J/K navigation, A/B insert, D D delete.
• Variable Explorer: Browse and inspect variables from notebook cells via hydrogen-next.
• Kernel Monitor: Track kernel status and resource usage via hydrogen-next.
• Inspector: Get documentation and introspection for objects via hydrogen-next.
• Export options: Save as Python scripts or HTML.

Installation

To install jupyter-next search for jupyter-next in the Install pane of the Pulsar settings or run ppm install jupyter-next. Alternatively, you can run ppm install asiloisad/pulsar-jupyter-next to install a package directly from the GitHub repository.

This package requires hydrogen-next.

Provided Service jupyter-next

Allows other packages to interact with Jupyter notebooks: access kernel management, run code, and monitor kernel status.

In your package.json:

{
  "consumedServices": {
    "jupyter-next": {
      "versions": {
        "1.0.0": "consumeJupyter"
      }
    }
  }
}

In your main module:

consumeJupyter(jupyter) {
  // Get kernel manager
  const kernelManager = jupyter.getKernelManager()

  // Get active notebook
  const notebook = jupyter.getActiveNotebook()

  // Run code
  const result = await jupyter.runCode('print("Hello")', 'python3')

  // Subscribe to kernel status changes
  jupyter.onDidChangeKernelStatus(({ kernelName, status }) => {
    console.log(`Kernel ${kernelName} is now ${status}`)
  })
}
