Support %run magic for IPython

[krassowski]

This is a conceptually similar task to the task of the code extractor, but instead of extracting some code from the file it adds code at each virtual document refresh operation.

We would need to open the file, process the included notebook into a virtual document and embed it in the current virtual document. This definitely goes to the future jupyterlab-lsp-python (or ipython) extension.

This could be simplified by replacing %run xyz.ipynb with from lsp.xyz import * and keeping a virtual document under lsp/xyz.py in LSP server (not an actual file), though this would require reserving a python name for the package

@krassowski Hello! I also encountered the same problem, is there any progress now?
