Compatibility with VS Code

[jbogar]

When the notebook runs in VS Code, ipynbname throws an error, but it works fine if the notebook is ran with jupyter notebook from terminal.

import ipynbname
ipynbname.path()

produces:

FileNotFoundError                         Traceback (most recent call last)
/Users/jbogar/dummy_notebook.ipynb Cell 2 in <cell line: 2>()
      [1](vscode-notebook-cell:/Users/jbogar/dummy_notebook.ipynb#W1sZmlsZQ%3D%3D?line=0) import ipynbname
----> [2](vscode-notebook-cell:/Users/jbogar/dummy_notebook.ipynb#W1sZmlsZQ%3D%3D?line=1) ipynbname.path()

File ~/opt/miniconda3/lib/python3.8/site-packages/ipynbname/__init__.py:93, in path()
     91     root_dir = Path(srv.get('root_dir') or srv['notebook_dir'])
     92     return root_dir / path
---> 93 raise FileNotFoundError(FILE_ERROR.format('path'))

FileNotFoundError: Can't identify the notebook path.

environment:

python == 3.8.13
ipynbname == 2021.3.2
ipykernel == 6.9.1
VS Code version == 1.70.1

Is that an expected behavior? Any idea why does it happen or how to fix it?

Thanks

We're facing similar problems, though it's inconsistent (current theory is the server launches differently when running on Linux, but we don't have the experience to confirm).

As a workaround, the path is exposed through a variable

snippet for extracting the path:

from IPython import get_ipython
ip = get_ipython()
path = None
if '__vsc_ipynb_file__' in ip.user_ns:
    path = ip.user_ns['__vsc_ipynb_file__']

path

Thanks @antdking - hope that helps others using VS Code!
