[IPython-dev] New IPEP for a multi-directory notebook in IPython
Fri Apr 12 06:51:25 CDT 2013
I have an implementation that I have been working on. I will get a pull request together. My code in filenbmanager became much cleaner and more understandable once I made a Notebook object. I also made a NotebookCollection object that managed all the possible lookups to find a notebook.
For URLs I have added two new routes
/notebook_direct which leads to urls like /notebook_direct//Users/paddy/foo.ipynb
/notebook_relative which has paths that are relative to the base notebook directory.
What issues were there previously with path based notebooks?
One question that I have run into is, what directory do New Notebooks end up in?
