```
$ bundle exec irb
Calling `DidYouMean::SPELL_CHECKERS.merge!(error_name => spell_checker)' has been deprecated. Please call `DidYouMean.correct_error(error_name, spell_checker)' instead.
irb(main):001:0> require 'json'

irb(main):002:0> require 'r10k/module_loader/puppetfile'

irb(main):003:0> puppetfile = R10K::ModuleLoader::Puppetfile.new(basedir: '/home/bastelfreak/code/controlrepo/').load

irb(main):004:0> mod = puppetfile[:modules].map {|mod| mod if mod.class == R10K::Module::Git}.compact.first

irb(main):005:0> mod.remote

irb(main):006:0>
