#8541 — Status of ipython-qtconsole

Hello,

I saw that a bunch of jupyter projects were uploaded into experimental.
It would be nice to have also the qtconsole part.

I would like to know if there is already an effort in order to package the current
ipython-qtconsole.

I would be glade to help package this module.

One of my package (spyder) depends on this module

Cheers

Frederic

Not as far as I know.  I'd be happy to review a package if that would
help.

Hello Julien

I just pushed here my wip package

git clone git+ssh://git.debian.org/git/python-modules/packages/python-qtconsole.git

I have debian/TODO.org file where I put the remaining things to do.

I would be glade if your could do a review (it si still work in progress)
But this is my first package for python-modules

Here the question which need to be answered before uploaded even to experimental

* qtconsole provide jupyter-qtconsole

  - [ ] for python3 what is the right scheme
    jupyter-qtconsole3 or jupyter3-qtconsole

    the problem is that jupyter-core provide only jupyter and not jupyter3
    so for now if I start
    jupyter qtconsole it start a Python2 kernel

    with jupyter-qtconsole3 -> jupyter qtconsole3 -> Python3
    with jupyter3-qtconsole -> jupyter ????


Cheers,
Fred


Ps: I will add the -doc file  :)

I think in jupyter this is meant to be handled by the --kernel option - ie

    jupyter qtconsole --kernel python2
    jupyter qtconsole --kernel python3

given the existence of non-python kernels (irkernel, ihaskell, iruby,
ijavascript, etc...)

ok it works

>    jupyter qtconsole --kernel python3

$ jupyter qtconsole --kernel python3

But if I list the kernel available I have just

~$ jupyter-kernelspec list
Available kernels:
  python3    /usr/lib/python3/dist-packages/ipykernel/resources


so it is really strange...

#8624

Hello,

I follow what is done with jupyter-core and distribute only the python3 scripts.

so now I have these binary packages:

python-qtconsole
python3-qtconsole
jupyter-qtconsole
ipython-qtconsole
ipython3-qtconsole
python-qtconsole-doc

where

ipython-qtconsole and ipython3-qtconsole are transition package

BUT

for now ipython-qtconsole provide the python module and the scripts.

ipython3-qtconsole depends on jupyter-qtconsole + python3-qtconsole (module + scipt)
ipython-qtconsole depends on python-qtconsole (no ore scripts)

is it ok like this ?

or should I add to ipython-qtconsole also the jupyter-qtconsole in order to provide the command line even if it add a python3 stack.

cheers


Frederic
