Error exporting with changed notebook_dir

[juanep97]

Hello,

I have python 2.7.11-1 on Ubuntu 16.04 and ipython-2.4.1-1 and jupyter (pip-installed).

I changed /home/user/.jupyter/jupyter_notebook_config.py from: c.NotebookApp.notebook_dir = u'' to c.NotebookApp.notebook_dir = u'/home/user/Workspace/Python' so that it starts in such folder automatically. However this seems to break hidecode. When exporting a notebook (for example, with html), it gives a 500 Internal Server Error in the browser and the following output:

[I 12:47:03.980 NotebookApp] hide_code: Starting HTML export for None
[E 12:47:03.981 NotebookApp] Uncaught exception GET /notebooks/Untitled.ipynb/export/html (127.0.0.1)

        with open(ipynb_file_name(args)) as f:
    IOError: [Errno 2] No such file or directory: u'Untitled.ipynb'

It seems that hidecode cannot find the notebook file, at the time of execution of /usr/local/lib/python2.7/dist-packages/hide_code/hide_code.py. The argument args of the get method of HideCodeHTMLExportHandler does not seem to contain the full path to the notebook file, so I think that is the problem (the change applied to jupyter configuration file is not reflected here).

I don't know if this is intended behavior but I thought I would report it anyway, as it is a bit irksome. If there is anyway to fix it or a work around I would like to know.

Thank you. This extension is definitely useful.

What version of hide_code are you using and did you install via nbextensions?

[juanep97]

Hello, This is the output of pip show hide_code:

Name: hide-code
Version: 0.4.0
Summary: A Jupyter notebook extension to hide code, prompts and outputs.
Home-page: https://github.com/kirbs-/hide_code
Author: Chris Kirby
Author-email: kirbycm@gmail.com
License: MIT
Location: /usr/local/lib/python2.7/dist-packages
Requires: jupyter, pdfkit, nbconvert

I installed it executing:

pip install hide_code
jupyter nbextension install --py hide_code
jupyter nbextension enable --py hide_code
jupyter serverextension enable --py hide_code

I also reinstalled it with the --sys-prefix to see if that was the reason, to no avail.

Not sure what's wrong here. Hide_code is using Jupyter's paths to access the underlying .ipynb file. If you navigate to http://localhost:8888/notebooks/Untitled.ipynb does the notebook open up?

[juanep97]

Yes, it does open. Have you confirmed the bug or is something affecting my installation solely?

It's a bug. Looks like the jupyter method I'm using to find the underlying file is a relative path. I'll have to do some digging in Jupyter's documentation to find an alternative.
