Overview

Describe dependency as an Hash indexed by type

Sample of use:

selector = lambda do |type|
  Bundler.environment.dependencies
         .select { |d| d.groups.include?(type) }.to_a
end

dependency = Dependency.new({
  runtime: selector.call(:default),
  development: selector.call(:development),
})

puts dependency.keep(:runtime).to_s
