How can I view all the gems for a specific gem group?

I'd like to see all the gems that are loaded for the test environment, with versions and dependencies. Is such a thing possible?

Solution

  • You could roll your own:

    require 'bundler/setup'

group = :development

deps = Bundler.load.dependencies.select do |dep|
  dep.groups.include?(group) or dep.groups.include?(:default)
end

puts "Gems included by the bundle in group #{group}:"
deps.each do |dep|
  spec = dep.to_spec
  puts "* #{spec.name} (#{spec.version})"
end

    Example Gemfile:

    source 'https://rubygems.org'


gem 'sinatra'
gem 'thor'

group :test do
  gem 'rspec'
end

group :development do
  gem 'rspec'
  gem 'pry'
end

    Example output:

    Gems included by the bundle in group development:
* sinatra (1.4.1)
* thor (0.17.0)
* rspec (2.13.0)
* pry (0.9.12)
