recursive-open-struct

OpenStruct subclass that returns nested hash attributes as RecursiveOpenStructs.

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

ros = RecursiveOpenStruct.new( { fooa: { foob: 'fooc' } } )

ros.fooa.foob # => 'fooc'

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

ros.fooa_as_a_hash # { foob: 'fooc' }

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

h = { :somearr => [ { name: 'a'}, { name: 'b' } ] }
ros = RecursiveOpenStruct.new(h, recurse_over_arrays: true )

ros.somearr[0].name # => 'a'
ros.somearr[1].name # => 'b'

Also, by default it will turn all hash keys into symbols internally:

h = { 'fear' => 'is', 'the' => 'mindkiller' } }
ros = RecursiveOpenStruct.new(h)
ros.to_h # => { fear: 'is', the: 'mindkiller' }

You can preserve the original keys by enabling :preserve_original_keys:

h = { 'fear' => 'is', 'the' => 'mindkiller' } }
ros = RecursiveOpenStruct.new(h, preserve_original_keys: true)
ros.to_h # => { 'fear' => 'is', 'the' => 'mindkiller' }

Installation

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

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

gem 'recursive-open-struct'

You may also install the gem manually :

gem install recursive-open-struct

Contributing

For simple bug fixes, feel free to provide a pull request.

For anything else (new features, bugs that you want to report, and bugs that are difficult to fix), I recommend opening an issue first to discuss the feature or bug. I am fairly cautious about adding new features that might cause RecursiveOpenStruct's API to deviate radically from OpenStruct's (since it might introduce new reserved method names), and it is useful to discuss the best way to solve a problem when there are tradeoffs or imperfect solutions.

When contributing code that changes behavior or fixes bugs, please include unit tests to cover the new behavior or to provide regression testing for bugs. Also, treat the unit tests as documentation --- make sure they are clean, clear, and concise, and well organized.
