Hirb provides a mini view framework for console applications and uses it to improve ripl(irb)'s default inspect output. Given an object or array of objects, hirb renders a view based on the object's class and/or ancestry. Hirb offers reusable views in the form of helper classes. The two main helpers, Hirb::Helpers::Table and Hirb::Helpers::Tree, provide several options for generating ascii tables and trees. Using Hirb::Helpers::AutoTable, hirb has useful default views for at least ten popular database gems i.e. Rails' ActiveRecord::Base. Other than views, hirb offers a smart pager and a console menu. The smart pager only pages when the output exceeds the current screen size. The menu is used in conjunction with tables to offer two dimensional menus.

It's ActiveSupport::Cache::MongoStore -- a MongoDB-based provider for the standard Rails cache mechanism. With an emphasis on fast writes and a memory-mapped architecture, Mongo is well-suited to caching. This gem aims to give you what the ubiquitous MemCacheStore does, but with Mongo's persistence. (And without having to put a second RAM devourer in an environment already running Mongo.)
