ipykernel

IPyKernel is a pure C implementation of IPython's messaging protocol.

Requirements

• IPython 1.0+
• ZeroMQ 2.x
• Jansson 2.1+

Building

Make sure that appropriate versions of libzmq and libjansson are installed on your system. For example in Ubuntu install libzmq-dev and libjansson-dev using apt-get. Otherwise you can build those libraries from source. Clone https://github.com/zeromq/zeromq2-x and https://github.com/akheron/jansson/tree/2.5, and follow their instructions how to build and install those libraries.

Now you can build ipykernel:

$ git clone git@github.com:mattpap/ipykernel.git
$ cd ipykernel
$ cmake -DCMAKE_C_COMPILER=/usr/bin/clang .
$ make

This created src/libipykernel.a and built examples in examples/. If you want to use the system wide compiler (possibly gcc) then remove CMAKE_C_COMPILER from cmake's argument list.

Examples

Start examples/echo in one terminal:

$ examples/echo
connect ipython with --existing profile-30914.json

Now in another terminal issue:

ipython console --existing profile-30914.json
Python 2.7.5 |Anaconda 1.7.0 (64-bit)| (default, Oct 25 2013, 18:42:10)
Type "copyright", "credits" or "license" for more information.

In [1]: Hi!
Out[1]: echo: Hi!

This simple kernel just echoes what you enter at the command prompt. By using command line options you can later reuse existing profile as follows:

$ examples/echo --profile profile-30914.json

Add --verbose option to see flow of messages between this kernel and IPython.
