Fun with vim and IPython kernel

#First of all, get the development version of ipython

cd /home/philip/Packages

git clone https://github.com/ipython/ipython.git

# install this into your own virtualenv (I'm assuming at this point that you have created a virtualenv and that you have activated it).

pip install /home/philip/Packages/ipython

# do a 'which ipython' to check that it worked


# you will need development libraries for zeromq

sudo apt-get install libzmq-dev

pip install pyzmq

# check pyzmq was installed into the virtualenv

(py26)philip@desktop:~/git/project$ python

Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)
[GCC 4.4.3] on desktop
Type "help", "copyright", "credits" or "license" for more information.

>>> import zmq
>>> zmq.__path__
['/home/philip/git/project/py26/lib/python2.6/site-packages/zmq']

# get the vim-ipython plugin

pip install git+https://github.com/ivanov/vim-ipython.git

# start up an IPython kernel.

 ipython kernel

# and you get output like:
(py26)philip@desktop:~/git/project$ ipython kernel
[IPKernelApp] To connect another client to this kernel, use:
[IPKernelApp] --existing kernel-32459.json


# startup vim and connect to the ipython kernel

gvim -c "IPython --existing kernel-32459.json"

or startup gvim and enter

:IPython --existing kernel-32459.json

In vim add this line:

3 + 4

Hit ctrl-s while still on this line and notice that a new window opens up with the result from the ipython kernel

now enter

a = 1

# from another shell

ipython qtconsole --existing kernel-32459.json

# to start up a qtconsole and connect it to the kernel

pip install pyside

ipython qtconsole --existing kernel-32459.json

do:

print a

And notice that the result of a is 1 because that is what we set a to from our vim session.
