FancyOpenStruct is a subclass of OpenStruct, and is a variant of RecursiveOpenStruct.

This gem allows you to convert nested hashes into a structure where keys and values can be navigated and modified via dot-syntax, like: foo.bar = :something. This particular gem also adds support for the Hash methods you know and love (such as length or merge), and also allows you to access and modify the contained data structure the same way that you would handle a normal Hash.

FancyOpenStruct allows for hashes within hashes to be called in a chain of methods:

require 'fancy-open-struct'

fos = FancyOpenStruct.new( { :fooa => { :foob => 'fooc' } } )

fos.fooa.foob # => 'fooc'

Also, if needed, nested hashes can still be accessed as hashes:

fos.fooa_as_a_hash # { :foob => 'fooc' }

Get and set values either via dot syntax, or hash syntax (Hash keys are handled as Symbols):

fos = FancyOpenStruct.new

fos.foo = 'bar'
fos[:foo] # 'bar'

fos[:baz] = 'qux'
fos.baz # 'qux'

fos.length # 2

FancyOpenStruct can also optionally recurse across arrays, although you have to explicitly enable it:

h = { :somearr => [ { :name => 'a'}, { :name => 'b' } ] }

fos = FancyOpenStruct.new(h, :recurse_over_arrays => true )

fos.somarr[0].name # => 'a'
fos.somarr[1].name # => 'b'

Available as a gem in rubygems, the default gem repository.

If you use bundler, just throw that in your gemfile :

gem 'fancy-open-struct'

You may also install the gem manually :

gem install fancy-open-struct

• 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.
