configure jupyter to spawn all new notebooks on the same port & server?

[Denis Akhiyarov]

I'm using basic integration of .ipynb files with Windows Explorer:

 

https://github.com/ContinuumIO/anaconda-issues/issues/267

 

However each notebook spawns a new notebook server.

 

Is there any way to force spawning new notebooks in the same notebook server & port using config files from jupyter?

Here are the settings that I have for notebook integration with file manager:

 

in CMD:

assoc .ipynb=IPYNBFILE

ftype IPYNBFILE="C:\Python\Python35\Scripts\ipython.exe" notebook "%%1"

In Registry (RegEdit)

[HKEY_CLASSES_ROOT\Directory\Background\shell\ipynb]

@="Open IPython Notebook server here"

[HKEY_CLASSES_ROOT\Directory\Background\shell\ipynb\command]

@="\"C:\\Python\\Python35\\Scripts\\ipython.exe\" \"notebook\" \"%1\""

[HKEY_CLASSES_ROOT\Directory\shell\ipynb]

@="Open IPython Notebook server here"

[HKEY_CLASSES_ROOT\Directory\shell\ipynb\command]

@="\"C:\\Python\\Python35\\Scripts\\ipython.exe\" \"notebook\" \"%1\""

Denis,

this should be possible by writing your own wrapper script. Currently,
you start the ipython.exe process with "notebook" and your filename as
parameters.

You should be able to write a script, say, "notebookwrapper.cmd", in
which you check if there already is an ipython.exe process running, and
if so, use the appropriate command line. Maybe you have to work with a
lockfile or the like.

This script, you would then use as

assoc .ipynb=IPYNBFILE
ftype IPYNBFILE="C:\path\to\notebookwrapper.cmd" "%%1"

Sorry to be a bit vague, but this should be enough to get you thinking
into the right direction. Unfortunately I cannot help in more detail
since I don't know Windows.

Cheers,
Andreas.

Hi Andreas,

Looks like your suggestion is still not possible even with a wrapper script:

https://github.com/ipython/ipython/issues/9342

So I guess let me give a try to nbopen again.

Thanks,

Denis

Don't forget to migrate from 'ipython notebook' to 'jupyter notebook' the CL argument parsing may be different.

nbopen is such a script :-)

Anyone using nbopen on Windows, install from master with these commands:

pip install flit
flit installfrom github:takluyver/nbopen
