SimplerEnum

Build Status Code Climate Test Coverage

SimplerEnum provides Rails like enumerated type.

It reproduces part of ActiveRecord::Enum features.

I hope it will help you when you want to use ActiveRecord::Enum in your not Rails repositories or older Rails version repositories.

Supported Ruby versions

  • Ruby 1.9
  • Ruby 2.x

Installation

Add this line to your application's Gemfile:

gem 'simpler_enum'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simpler_enum

Usage

Any class can include SimplerEnum and you can define an enumerated type like this:

require "simpler_enum"

class Person
  include SimplerEnum

  simpler_enum mood: %i(awesome excellent great good fine)

  def initialize(mood: :fine)
    self.mood = mood
  end
end

Or,

require "simpler_enum"

class Person
  include SimplerEnum

  simpler_enum mood: {
    awesome: 0,
    excellent: 1,
    great: 2,
    good: 3,
    fine: 4
  }

  def initialize(mood: :fine)
    self.mood = mood
  end
end

Both behave like this:

[1] pry(main)> Person.moods
=> {:awesome=>0, :excellent=>1, :great=>2, :good=>3, :fine=>4}
[2] pry(main)> necojackarc = Person.new(mood: :awesome)
=> #<Person:0x007fd5cbbf5dd0 @mood=0>
[3] pry(main)> necojackarc.awesome?
=> true
[4] pry(main)> necojackarc.excellent?
=> false
[5] pry(main)> necojackarc.great!
=> :great
[6] pry(main)> necojackarc.awesome?
=> false
[7] pry(main)> necojackarc.great?
=> true
[8] pry(main)> necojackarc.mood = :fine
=> :fine
[9] pry(main)> necojackarc.great?
=> false
[10] pry(main)> necojackarc.fine?
=> true
[11] pry(main)> necojackarc.mood = 1 # excellent
=> 1
[12] pry(main)> necojackarc.fine?
=> false
[13] pry(main)> necojackarc.excellent?
=> true
[14] pry(main)> necojackarc.mood
=> :excellent
[15] pry(main)> necojackarc.mood = "good"
=> "good"
[16] pry(main)> necojackarc.mood
=> :good
