Bundler: How do I get the groups from the current Gemfile at runtime?

Question

I already have this...

File.read(Bundler.default_gemfile).scan(/group :(\\w+)/).flatten

with an example output of

["production", "test", "development"]

...but Im hoping there is a better way?

Thank you!

Answer 1

Seems a bit cleaner:

> Bundler.definition.groups
# => [:default, :development, :test]

Of course this returns the :default group, which you may wish to get rid of.
