EasyClassConstants

Gem adds class methods to create readable, writable and accessible constants.

Installation

Add this line to your application's Gemfile:

gem 'easy_class_constants'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easy_class_constants

Usage

Adding constants to your class is easy:

class ECCObject
  include EasyClassConstants

  readable_constant :read_only, 'R'
  writable_constant :write_only, 'W'
  accessible_constant :read_write, 'RW'
  hash_indexed_by_readable_constants(:mapping, [[:internal_error, 0, 'Internal Error - Try Again Later'],
                                          [:network_error, 1, 'Network Error - Check With Your Admin']])

  hash_indexed_by_readable_constants(:simple_mapping, [[:HELLO_WORLD, 'Hello World'],
                                          [:HELLO_KITTY, 'Hello Kitty']])
                                  
end

Then you can call:

ECCTestObject.INTERNAL_ERROR                 #will return 0
ECCTestObject.SIMPLE_MAPPING[:HELLO_KITTY]   # will return 'Hello Kitty'
ECCTestObject.SIMPLE_MAPPING.HELLO_KITTY     # will return 'Hello Kitty'
ECCTestObject.READ_WRITE                     # will return 'RW'
