Mash is an extended Hash that gives simple pseudo-object functionality that can be built from hashes and easily extended. It is designed to be used in RESTful API libraries to provide easy object-like access to JSON and XML parsed hashes.
mash = Hashie::Mash.new mash.name? # => false mash.name # => nil mash.name = "My Mash" mash.name # => "My Mash" mash.name? # => true mash.inspect # => <Hashie::Mash name="My Mash"> mash = Mash.new # use bang methods for multi-level assignment mash.author!.name = "Michael Bleigh" mash.author # => <Hashie::Mash name="Michael Bleigh">
Dash is an extended Hash that has a discrete set of defined properties and only those properties may be set on the hash. Additionally, you can set defaults for each property.
class Person < Hashie::Dash property :name property :email property :occupation, :default => 'Rubyist' end p = Person.new p.name # => nil p.email = 'email@example.com' p.occupation # => 'Rubyist' p.email # => 'firstname.lastname@example.org' p[:awesome] # => NoMethodError p[:occupation] # => 'Rubyist' p = Person.new(:name => "Bob") p.name # => 'Bob' p.occupation # => 'Rubyist'
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
