• Status bar integration showing kernel status

Installation

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

• A: Insert cell above (command mode)
• B: Insert cell below (command mode)

• Y: Change to code (command mode)

API

The package provides a service that other packages can consume:

// In your package
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}`)
  })
}
