BundledGems

Install a gem specified in Gemfile.lock without running bundle install.

Motivation

After the emergence of Docker, libraries (such as rubygems) are installed inside Docker or Docker Volume, but we sometimes want to install specific version of libraries in Host machine.

Here comes the bundled_gems command (bgem). bgem reads your Gemfile.lock and install the specific version of the gem.

Installation

$ gem install bundled_gems

Then, bgem command is available.

Usage

$ bgem                    
Commands:
  bgem help [COMMAND]         # Describe available commands or one specific command
  bgem install [BUNDLED_GEM]  # install [BUNDLED_GEM] specified in `Gemfile.lock`
  bgem list                   # bundle list without `bundle install`
  bgem version                # bundled_gems version

List gems

$ bgem list
Gems included in `Gemfile.lock`:
  * actionpack, 5.2.3
  * actionview, 5.2.3
  * activesupport, 5.2.3
  ...(snip)...

Install gem

$ bgem install gem_name

Example

$ gem install bundled_gems  # Install bundled_gems and `bgem` command is available
$ bgem install rubocop      # install rubocop specified in `Gemfile.lock`
$ rubocop                   # Run rubocop

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
