DotHash

Code Climate Build Status

A very efficient gem that lets you use hashes as object properties. It is almost as fast as a plain Hash since it's complexity is also linear, O(n) # where N is the number of nested parents of the given property.

Installation

Add this line to your application's Gemfile:

gem 'dot_hash'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dot_hash

Usage

some_hash = {size: {height: 100, width: 500}, "color" => "red"}
properties = some_hash.to_properties

properties.size.height # returns 100, it is the same as some_hash[:size][:height]
properties.color       # returns "red", it works with Strings and Symbol keys
properties[:color]     # returns "red", can be used like a hash with string keys
properties["color"]    # returns "red", can be used like a hash with symbol keys

# App Settings
class Settings < DotHash::Settings
  load 'path/to/some/settings.yaml', 'path/to/settings-directory/', {something: 'Some Value'}
end

# Use the settings as a Singleton
Settings.something
Settings.other.stuff.from_yml_settings

# Create a settings instance from some YML
swagger = Settings.new Rails.root.join('config', 'my-swagger.yml')

swagger.info.title # returns the title from swagger doc
