Hashie

Hashie is a growing collection of tools that extend Hashes and make them more useful.

Installation

Hashie is a gem and is available on Gemcutter. If you don't have Gemcutter, install it:

gem install gemcutter
gem tumble

Then you can install Hashie:

gem install hashie

Mash

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.

Example:

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

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.

Example:

class Person < Hashie::Dash
  property :name
  property :email
  property :occupation, :default => 'Rubyist'
end

p = Person.new
p.name # => nil
p.email = 'abc@def.com'
p.occupation   # => 'Rubyist'
p.email        # => 'abc@def.com'
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.
