lite_enum

A short and sweet enumerator class for usage with ActiveRecord, most likely.

Goals:

• Concise
• Readable
• Useful for DOBT's stack
• Plain ol' Ruby API
• No auto-generation of predicate methods like in ActiveRecord::Enum

Usage

# Gemfile
gem 'lite_enum'

# app/models/foo.rb
class Foo < ActiveRecord::Base
  def self.sizes
    LiteEnum.new(:small, :medium, :large)
  end
end

Foo.sizes[1] # => :small
Foo.sizes[:small] # => 1
foo = Foo.new(size: Foo.sizes[:small])
foo.size # => 1
foo.size == Foo.sizes[:small] # => true
