OpenStructDeep

Make deeper ostruct, such as method chain of javascript object

Installation

Add this line to your application's Gemfile:

gem 'ostruct_deep'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ostruct_deep

Usage

require 'ostruct_deep'

# Put your hash structure for the first parameter
hash = {name: "John Smith", age: 70, pension: 300}
person = OpenStructDeep.new(hash)

 or

# It works also
person = OpenStructDeep.new(name: "John Smith", age: 70, pension: 300)

 or

# Another way you can
person = OpenStructDeep.new
person.name    = "John Smith"
person.age     = 70
person.pension = 300

 then

puts person.name     # -> "John Smith"
puts person.age      # -> 70
puts person.address  # -> nil

.to_ostruct_deep

• return : object of OpenStructDeep ruby hash = {name: "John Smith", age: 70, pension: 300, friends: ["Pablov", "Harry", "Peter"]} hash.to_ostruct_deep # -> <OpenStructDeep name="John Smith", age=70, pension=300, friends=["Pablov", "Harry", "Peter"]>

.to_h

• return : object of hash ruby hash = {name: "John Smith", age: 70, pension: 300, friends: ["Pablov", "Harry", "Peter"]} osd = OpenStructDeep.new(hash) # -> <OpenStructDeep name="John Smith", age=70, pension=300, friends=["Pablov", "Harry", "Peter"]> osd.to_h # -> {:name=>"John Smith", :age=>70, :pension=>300, :friends=>["Pablov", "Harry", "Peter"]}

Originals Problem in (OpenStructure)

In original ostruct (rubysl-ostruct) do below:

hash = { "country" => "Australia", :population => 20_000_000, :info => { from: 1392, to: 1910 } }
data = OpenStruct.new(hash)

p data        # -> <OpenStruct country="Australia" population=20000000, info={:from=>1392, :to=>1910}>
p data.country # -> "Australia"
p data["country"] # -> "Australia" # still works.

p data.info # -> {:from=>1392, :to=>1910}

# Problem Case
p data.info.from # -> NoMethodError: undefined method `from' for {:from=>1392, :to=>1910}:Hash

Solved in new one (OpenStructureDeep)

In ostruct_deep do below:

Sample Structure

The new hash has many stage and includes array.

hash = 
{ "country" => "Joseon",
   :population => 20000000,

   :info => { # 2nd stage
     :from => 1392,
     :to => 1910,

     :started_by => { # 3rd stage
       name: "Lee Seong Gye"
     }
   },

   # Array container
   :kings => [
     { :name => "SeJong",
       :terms => { # 2nd stage in array element
         :from => 1418,
         :to => 1450
       }
     },
     { :name => "JeongJo",
       :info => {
         :what => "ever"
       }
     }
   ]
}

Works

OpenStructDeep works fine :

data = OpenStructDeep.new(hash)

p data          # -> <OpenStructDeep country="Joseon", population=20000000, info=#<OpenStructDeep from=1392, to=1910, started_by=#<OpenStructDeep name="Lee Seong Gye">>, kings=[#<OpenStructDeep name="SeJong", terms=#<OpenStructDeep from=1418, to=1450>>, #<OpenStructDeep name="JeongJo", info=#<OpenStructDeep what="ever">>]>
p data.country              # -> 'Joseon'
p data.info                 # -> <OpenStructDeep from=1392, to=1910, started_by=#<OpenStructDeep name="Lee Seong Gye">>
p data.info.started_by.name # -> 'Lee Seong Gye'

p data.kings    # -> [#<OpenStructDeep name="SeJong", terms=#<OpenStructDeep from=1418, to=1450>>, #<OpenStructDeep name="JeongJo", info=#<OpenStructDeep what="ever">>]
p data.kings.is_a?(Array)   # -> true

# ... you can parse structure whatever you want
