Automating jupytext Sync on Save in emacs-ipython-notebook

If you are a user of emacs-ipython-notebook (EIN) and have been working with Jupyter notebooks, you might have encountered the need to sync your .ipynb files with Python scripts using jupytext. While jupytext conveniently handles synchronization within standalone Jupyter notebooks, integrating this functionality into your Emacs setup can be trickier. Let’s break down how to automatically sync your files with jupytext whenever you save your notebook in Emacs.

The Problem

You are leveraging EIN for interactive support and jupytext for converting .ipynb files into .py files. However, you currently find yourself running a shell command every time you want to sync your files. Here's a snippet of code you attempted:

This approach doesn’t work as expected because buffer-file-name returns nil when you are in EIN's interactive mode. So, you need a solution that accesses the correct file path for synchronization.

The Solution

The central hurdle when working with EIN is that it utilizes polymode, which means the working buffer is not directly tied to the notebook file. Fortunately, we can access the notebook path through the ein package. Here’s how you can modify your approach to achieve the desired automation.

Step 1: Access the Notebook Path

Instead of using buffer-file-name, you can retrieve the notebook name with the following function:

This line allows you to dynamically get the current notebook's name, which is necessary for your synchronization.

Step 2: Modify Your Sync Function

You will need to change your sync function to incorporate the new way of accessing the notebook name. Here’s an updated version of your function utilizing advice to hook into the notebook save event:

Step 3: Understanding the Code

Advice Function: This my@ sync-jupytext function wraps around ein:notebook-save-notebook-success, which triggers when a notebook is successfully saved.

Applying Original Functionality: The function first calls the original save function (orig-fn), ensuring that the notebook saves as it normally would.

Syncing with Jupytext: After a successful save, it executes the sync command, taking the notebook name dynamically from your current context.

Conclusion

By following the steps laid out above, you can effectively automate the syncing of your notebooks using jupytext in Emacs. This eliminates the need to run shell commands manually and streamlines your workflow significantly.

Now, every time you save your notebook, it will automatically sync with the corresponding Python script, helping you maintain an efficient code review process and a clean workflow!

Remember to always test your LaTeX snippets in a safe environment before applying them to your main codebase. Happy coding!
