IPython Kernel Connection File Location

[Rafi Bin-Nun]

Hi, When launching Leo with the IPython bridge  python launchLeo.py --ipython  I get what's listed below... am I doing something wrong?

C:\Program Files (my)\Leo-5.1-final>python launchLeo.py --ipython

C:\Program Files (my)\Anaconda3_py35\lib\site-packages\IPython\kernel\__init__

.py:13: ShimWarning: The `IPython.kernel` package has been deprecated. You shoul

d import from ipykernel or jupyter_client instead.

** isPython3: True

Leo 5.1-final, build 20150416183122, Thu Apr 16 18:31:22 CDT 2015

Not running from a git repo

Python 3.5.1, PyQt version 4.8.7

Windows 7 AMD64 (build 6.1.7601) SP1

NOTE: When using the `ipython kernel` entry point, Ctrl-C will not work.

To exit, you will have to explicitly quit this process, by either sending

"quit" from a client, or using Ctrl-\ in UNIX-like environments.

To read more about this, see https://github.com/ipython/ipython/issues/2049

To connect another client to this kernel, use:

    --existing kernel-10376.json

This is an issue with the kernel connection file (kernel-X.json) location. 

connect.py is expecting it in ~\.ipython\profile_default\security and instead it's being placed in ...\AppData\Roaming\jupyter\runtime. 

Updating  c.ConnectionFileMixin.connection_file  in  ~.ipython\profile_default\ipython_kernel_config.py to a static location allows Leo's IPython bridge to connect but prevents running multiple kernels concurrently unless the c.ConnectionFileMixin.connection_file is reverted after the bridge comes up.

Will update post if I find a better solution.

​Thanks for all your posts about Leo, IPython & Jupyter. Getting Leo's IPython support working is important. It's been on the back burner for far too long. At present, this is scheduled for Leo 5.1.2, which is to say, I'll start work on it in a week or two.

Does anyone have any ideas why the connection files are being written to ~\AppData\Roaming\jupyter\runtime\... instead of the expected ~\.ipython\profile_default\security\...? 

​This will be part of the work scheduled for Leo 5.1.2.
