Official gem repository: Ruby kernel for Jupyter/IPython Notebook

IRuby

This is a Ruby kernel for Jupyter and is part of SciRuby. You can try it at try.jupyter.org.

Quick start

The installation instructions are divided according to environments mainly because of ZeroMQ.

Ubuntu 16.04

At first install Jupyter. I recommend an installation using Anaconda Python 3.6 version.

After that, install the Ruby gem.

sudo apt install libtool libffi-dev ruby ruby-dev make
gem install cztop

sudo apt install git libzmq-dev autoconf pkg-config
git clone https://github.com/zeromq/czmq
cd czmq
./autogen.sh && ./configure && sudo make && sudo make install

gem install iruby
iruby register --force

Now you can select Ruby kernel in Jupyter Notebook with:

jupyter-notebook

Windows

At first install git and Jupyter. I recommend an installation using Anaconda.

Run the following commands on Ruby command prompt:

gem install cztop
gem install iruby
iruby register --force

Now you can select Ruby kernel in Jupyter Notebook with:

jupyter-notebook

Mac

I recommend an installation using Anaconda.

After that, run the following commands.

brew install rbenv automake gmp libtool wget
rbenv install 2.4.1
rbenv global 2.4.1
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc

brew install zeromq
brew install czmq --HEAD
gem install cztop iruby
iruby register --force

If you are using macports, run the following commands. port install libtool autoconf automake autogen gem install ffi-rzmq gem install iruby

FreeBSD

At first install IPython/Jupyter. There is a pyzmq ports (ports/net/py-pyzmq) which depends on libzmq4, however, it doesn't works with ipython. Therefore we use libzmq3 like the following:

1. make your ports tree up-to-date.

2. replace LIBDEPENDS line in ports/net/py-pyzmq/Makefile

   LIB_DEPENDS=    libzmq.so:${PORTSDIR}/net/libzmq4

   with

   LIB_DEPENDS=    libzmq.so:${PORTSDIR}/net/libzmq3

3. install related packages

   $ sudo pkg install libzmq3 py27-qt4-gui py27-pexpect-3.3 py27-qt4-svg py27-pygments py27-Jinja2 py27-tornado py27-jsonschema

4. make install using ports

   $ cd /usr/ports/net/py-pyzmq
   $ sudo make install
   $ cd /usr/ports/devel/ipython
   $ sudo make install

Then, install iruby and related ports and gems. shell $ sudo pkg install rubygem-mimemagic $ sudo gem install ffi-rzmq # install ffi, ffi-rzmq-core and ffi-rzmq $ git clone https://github.com/SciRuby/iruby.git $ cd iruby $ gem build iruby.gemspec $ sudo gem install iruby-0.2.7.gem

Installation for jRuby

Since jRuby is fully compatible with Ruby version 2.2, it is possible to use iruby with jRuby. It can be helpful if you want to use java classes in your iruby notebook. This will require the following software:

• jRuby version >= 9.0.4.0
• cztop gem
• this iruby gem

After installation, make sure that your env is set up to jruby.

$ env ruby -v

If you use RVM, it is enough to switch the current version to jruby. If you have already used iruby with a different version, you need to generate a new kernel:

$ iruby register --force

After that you can use iruby with jRuby in usual way.

After the installation

Take a look at the example notebook and the collection of notebooks which includes a Dockerfile to create a containerized installation of iruby and other scientific gems. You can find the prebuild image at dockerhub.

Required dependencies

• Jupyter >= 3.0.0
• Ruby >= 2.1.0

If you install IRuby with CZTop, CZMQ >= 4.0.0 is added to the list above.

If you install IRuby with ffi-rzmq, libzmq >= 3.2 is added to the list above.
