Rails initializer to remove old submodules

remove_old_submodules.rb

# Git doesn't remove submodules from your working tree when you pull. This Rails
# initializer will take care of it for you, so developers don't have to do
# anything.

paths = %w(vendor/gems/first_gem-1.0.0
           vendor/gems/another_gem-1.0.0)

paths.each do |path|
  dir = Rails.root.join(path)
  if File.directory?(dir)
    puts "Automatically deleting #{dir.sub(Rails.root.to_s + '/', '')}, since it's an old submodule that we removed"
    FileUtils.rm_rf dir
  end
