Magic::Array

Provides easy way for grouping constants into arrays

Installation

Add this line to your application's Gemfile:

gem 'magic-array'

And then execute:

$ bundle

Or install it yourself as:

$ gem install magic-array

Usage

from_existing(pattern)

class Foo
  BAR_1 = 1
  BAR_2 = 2
  #...
  BAR_N = Float::INFINITY

  BARS = [
    BAR_1,
    BAR_2,
    #...,
    BAR_N
  ]
end

become

class Foo
  BAR_1 = 1
  BAR_2 = 2
  #...
  BAR_N = Float::INFINITY

  BARS = from_existing /^BAR/ #[1, 2, ..., Infinity]
end

so after adding new constant (e.g. BAR_N+1) you will not need to modify arrays constant.
