Heroku Open Source Plugins etc

YamlDb

YamlDb is a database-independent format for saving and restoring data, in the same way that schema.rb is a database-independent format for schema.

Install in Rails 2.1:

script/plugin install git://github.com/adamwiggins/yaml_db.git

In Rails 2.0 or below:

script/plugin install http://github.com/adamwiggins/yaml_db.git

If the above doesn't work for some reason, you can use the out-of-date svn repo:

script/plugin install http://opensource.heroku.com/svn/rails_plugins/yaml_db

Heroku Client Gem

Rubygem with a command-line interface for accessing the public API to create and manage Heroku apps.

gem install heroku

Send patches and feedback to the Heroku mailing list.
