This is one implementation of the Builder Pattern in the Ruby programming language. This is primarily used for composing objects to transport a set of data to a receiver with a specific payload. The advantage of using a builder over a plain Hash is using explicit methods to set required fields, and getting a common way to present your data to the receiver. By default,
.build will transform your data into a hash, but you can override this method to create your preferred format.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install vandelay
require 'vandelay' class ToDoBuilder include :: made_of :text, :title, :completed_at made_of :created_at, default: Time.now.iso8601 end new_todo = ToDoBuilder.new new_todo.set_title('Write a ruby package') new_todo.set_text('Ruby is fun to write, so why not write a gem?') new_todo.set_completed_at(Time.now.iso8601)
After checking out the repo, run
bin/setup to install dependencies. You can also run
bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run
bundle exec rake install. To release a new version, update the version number in
version.rb, and then run
bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the
.gem file to rubygems.org.
