Note plugins are deprecated in Rails 4. This plugin will only work for Rails 3 and below.

Renaming your app in Rails 3 is no longer a hassle. This plugin allows you to rename your Ruby on Rails 3 app seamlessly with a single command.

% rails plugin install git://github.com/get/Rename.git

Manually rename your main project directory to SweetNewName and run:

% rails g rename_to SweetNewName

That will rename your app in the following files:

config/application.rb
config/environment.rb
config/environments/development.rb
config/environments/test.rb
config/environments/production.rb
config/routes.rb
config.ru
config/initializers/secret_token.rb
config/initializers/session_store.rb

Remove the plugin directory manually or simply:

rm -r "vendor/plugins/Rename"
