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
