IRuby::Dependencies

IRuby::Dependencies is a thin wrapper around bundler/inline for injecting Ruby dependencies into Jupyter Notebooks along with their system dependencies. For example,

require 'iruby/dependencies'

dependencies do 
  gem 'http'
  gem 'addressable'
end

Installation

$ gem install iruby-dependencies

You'll have to restart any IRuby kernels already running.

Configuration

Most Jupyter notebooks run in highly reproducible environments (e.g. Docker containers). An IRuby::Dependencies can be created that maps gems to the commands that must be executed before that gem can be installed. The config location should be saved as a Bundler config with the key dependencies.config. The config location can be a local file path or URL. For example:

$ bundle config dependencies.config /home/jovyan/dependencies.config

RemThe config file itself is a JSON file that maps gem names to commands that should be executed before the gem is installed. For instance, in a CentOS/RHEL environment, the config entry would install the gsl YUM package before installing the gsl RubyGem:

{ 
    'gsl': [
        ["exec", "yum install gsl"]
    ]
}

Usage

To see the normal bundler output, pass verbose: true to the dependencies method:

dependencies verbose: true do 
  gem 'http'
  gem 'addressable'
end
