GemDependenciesVisualizer

Add this line to your application's Gemfile:

gem 'gem_dependencies_visualizer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gem_dependencies_visualizer

To produce a graph of your gem dependencies, pass the content of a Gemfile.lock and, if available, the content of the Gemfile as is as an input to the visualizer. For gems, you can also use a different method to pass the gemspec and your Gemfile.lock content. You can (optionaly) pass a graph name you might want to give to the .png file to be produced.

To use it just run the following in your code:

GemDependenciesVisualizer.produce_gems_graph(gemfile_content, gemfile_lock_content, graph_name, options = {})
GemDependenciesVisualizer.produce_gems_graph_from_gemspec(gemspec_file_content, gemfile_lock_content, graph_name, options = {})

Available options you could use are:

• :graph_direction, which will set how your graph will be produced with options ** top-bottom, for the graph to start on the top towards the bottom ** bottom-top, for the graph to start on the bottom towards the top ** right-left, for the graph to start on the left towards the right ** anything else is set to default, which is left to right.
• :keep_gem_version, which will keep the versions set in the Gemfile.lock
• :specific_directory, which will mark the folder in which the graphs should be rendered. All graphs are always created inside gem_dependencies_graphs folder. Default namespace used is app/assets/images.

For example by using the produced Gemfile.lock in this gem, we can get the following:

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
