Create objects in a sandbox

This project grew out of a project where I needed to create complicated object definitions and didn’t want to write it out in classic ruby syntax (clunky and fragile). So, this gem lets you easily generate classes inside a sandbox and clean it out the namespace between tests.

gem install cat

require 'cat'

Add a single class

> Sandbox.add_class("Foo")
> Sandbox::Foo.new
 => #<Sandbox::Foo:0x007ff5a2829930>

Add a subclass

> Sandbox.add_class("Foo::Bar")
> Sandbox::Foo::Bar.new
 => #<Sandbox::Foo::Bar:0x007ff5a281f098>

Add some attributes to a class

> Sandbox.add_attributes("Foo::Bar", "id", :title)
> fb = Sandbox::Foo::Bar.new(id: 10, title: "I like chicken") # it adds an initialize method for you too
> fb.id
 => 10
> fb.title
 => "I like chicken"

Add a method to a class

> Sandbox.add_method("Foo::Bar", :food, lambda{"I like liver"})
> fb = Sandbox::Foo::Bar.new
> fb.food
 => "I like liver"

Or do it with a block

> Sandbox.add_method("Foo::Bar", :food) {"Meow mix meow mix"}
> fb = Sandbox::Foo::Bar.new
> fb.food
 => "Meow mix meow mix"

Class methods work the same way

> Sandbox.add_class_method("Foo::Bar", :babar, lambda{"king of elephants"})
> Sandbox::Foo::Bar.babar
 => "king of elephants"

When you’ve cluttered your namespace beyond repair, just delete it all

> Sandbox.cleanup!  # or of course, use the alias Sandbox.scoop! :)

• Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet.

• Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it.

• Fork the project.

• Start a feature/bugfix branch.

• Commit and push until you are happy with your contribution.

• Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.

• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
