IRuby

Gem Version Build Status Binder

IRuby is a Ruby kernel for Jupyter project.

Installation

Requirements

If both ffi-rzmq and cztop are installed, ffi-rzmq is used. If you prefer cztop, set the following environment variable.

export IRUBY_SESSION_ADAPTER="cztop"
  • We recommend the Pry backend for full functionality.
  • If you want to install the latest version of IRuby from the source code, try specific_install.
gem specific_install https://github.com/SciRuby/iruby

Ubuntu

Install Jupyter with Anaconda (recommended).

17.04 to 19.04

sudo apt install libtool libffi-dev ruby ruby-dev make
sudo apt install libzmq3-dev libczmq-dev

gem install ffi-rzmq
gem install iruby --pre
iruby register --force

16.04

CZTop requires CZMQ >= 4.0.0 and ZMQ >= 4.2.0. The official packages for Ubuntu 16.04 don't satisfy these version requrements, so you need to install from source.

sudo apt install libtool libffi-dev ruby ruby-dev make
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 cztop
gem install iruby --pre
iruby register --force

Windows

Install git and Jupyter with Anaconda (recommended). DevKit is necessary for building RubyGems with native C-based extensions.

Install ZeroMQ.

pacman -S mingw64/mingw-w64-x86_64-zeromq
gem install ffi-rzmq
gem install iruby --pre
iruby register --force

macOS

Install ruby with rbenv or rvm. Install Jupyter with Anaconda (recommended).

Homebrew

brew install automake gmp libtool wget
brew install zeromq --HEAD
brew install czmq --HEAD
# export LIBZMQ_PATH=$(brew --prefix zeromq)/lib
# export LIBCZMQ_PATH=$(brew --prefix czmq)/lib
# gem install cztop
gem install ffi-rzmq
gem install iruby --pre
iruby register --force

MacPorts

If you are using macports, run the following commands.

port install libtool autoconf automake autogen
gem install ffi-rzmq
gem install iruby

Docker

Try RubyData Docker Stacks. Running jupyter notebook:

docker run -p 8888:8888 rubydata/datascience-notebook

Installation for JRuby

You can use Java classes in your IRuby notebook.

  • JRuby version >= 9.0.4.0
  • cztop gem
  • iruby gem

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

Notebooks

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.
