Question

Answer 1

In case you want to have your file loaded in the irb session and you are using Ruby 2+ you can load a file in irb like this:

irb -r ./the_name_of_your_file.rb

This opens an irb session with the given file loaded.

Imagine you have file with a class like this:

class Example
  def initialize(name)
    @name = name
  end

  def print__example
    p name
  end
end

You will be able to use the Example class in the irb session.
