An adapter that wraps common ruby data-structures and makes them look like proper Objects.
struct = DeepStruct.wrap({"a" => { "b" => "bingo!"}})
struct.a.b
=> "bingo!"
gem install deepstruct
Or if you use the awesomeness that is bundler, you stick this in your Gemfile:
gem "deepstruct"
struct = DeepStruct.wrap({:awesome => [1,2,3, {"a" => "hello from the abyss"}]})
struct.awesome[3].a
=> "hello from the abyss"
You can also write back through the wrapper with indifferent access
struct = DeepStruct.wrap({:a => 10, "b" => 20})
struct.a = 10
struct.b = 20
struct
=> #<DeepStruct::HashWrapper {:a=>10, "b"=>20}>
When you want to you can still use hash-style syntax when accessing your DeepStructs. These accessors implement indifferent access too.
struct = DeepStruct.wrap({:a => {1 => 'One', 2 => 'Two'}})
struct.a[1]
=> "One"
struct["a"][1]
=> "One"
struct["b"] = "Hello"
struct[:b]
=> "Hello"
struct.b
=> "Hello"
If DeepStruct is getting in your way, you can always get access to the raw content by unwrapping it:
struct = Deepstruct.wrap({"hello => "world"})
struct.unwrap
=> {"hello" => "world"}
DeepStruct is a perfect companion to your json-oriented application!
struct = DeepStruct.wrap(JSON.parse('{"full_name": "Don Corleone"}'))
puts struct.to_json
{"full_name":"Don Corleone"}
