Shows how to define a .root method for a gem module
Raw
gem_root.rb
# in example_gem/lib/example_gem.rb
module ExampleGem
# ExampleGem.root
def self.root
current_file_name = __FILE__
path_to_current_file = File.expand_path(current_file_name)
# get out of example_gem.rb file and then out of /lib to get to root
root_path = Pathname.new(path_to_current_file) + "../.."
# instead of `+ "../.."`, parent.parent also works
return root_path
end
