Overview

composite_range is a simple class if you need to deal with more than one range at once.

Installation

Add this line to your application's Gemfile:

gem 'composite_range'

And then execute:

$ bundle

Or install it yourself as:

$ gem install composite_range

Usage

You can simply create a composite range by passing all ranges that you plan to deal with:

range = CompositeRange.new([1..10, 12..45, 37..98])

If you have some ranges to exclude from the main one:

range = CompositeRange.new(1..20, exclude: [3..5, 9..14])

After creating of instance, you can do the range operations: include?, cover?, begin, end, first, last.

Adding ranges dynamically:

range << (2..12)

or

range[] = (2..12)

Getting range by index:

range[index]
