Contrived example demonstrating microgem dependencies

contrived is a microgem that depends on another microgem array_range, however gemspecs don't support DVCS dependencies. So how do we solve this without prematurely denting the universe?

Just use bundler.

Usage

Add all microgems to your project's Gemfile:

gem 'contrived', gist: 'b80fe32305890c2a8286'
gem 'array_range', gist: 'be9c16b2cd94abf6625c'

Live example

$ git clone https://gist.github.com/b80fe32305890c2a8286.git contrived
...
$ cd contrived
$ bundle
...
$ bundle exec ruby -e 'require "contrived";puts Contrived.new.foo'
0..3
$

contrived.gemspec

Gem::Specification.new do |s|
  s.name         = 'contrived'
  s.summary      = 'contrived'
  s.description  = 'contrived'
  s.version      = '0.0.1'
  s.platform     = Gem::Platform::RUBY
 
  s.files        = ['contrived.rb']
  s.require_path = '.'
 
  s.author      = 'Barry Allard'
  s.email       = 'barry.allard@gmail.com'
  s.license     = 'MIT'
  s.homepage    = 'https://gist.github.com/steakknife/b80fe32305890c2a8286'
 
  s.add_dependency('array_range', [">= 0.0.1", '< 1'])
end

contrived.rb

require 'array_range'

class Contrived
  def foo
    [1,2,3,4].range
  end
end

Gemfile

gemspec

gem 'array_range', git: 'https://gist.github.com/be9c16b2cd94abf6625c.git'
