Hi all,
A simple trick I want to share with you if you are using Bundler (or rails 3)
It matters if you want to install wirble gem in your workstation but not in your server

Sometimes, you want to include some gem that are not mandatory for your application to run but you want to use in your workstation. E.g wirble, awesome_print etc … or other debugging tools

Just write something like this in your Gemfile

# Gemfile
if File.exist?(file = File.expand_path('../myGemfile',__FILE__))
  instance_eval(File.read(file))
end

Now in your myGemfile

# myGemfile
gem 'wirble'
gem 'awesome_print'

That’s all! You can now require ‘wirble’ or ‘awesome_print’ in your rails console
