ripl is a light shell that encourages common middleware for shells i.e. rack for ruby shells. It is also a modular alternative to irb. Like irb, it loads ~/.irbrc, has autocompletion and keeps history in ~/.irb_history. Unlike irb, it is highly customizable via plugins and supports commands i.e. ripl-play. This customizability makes it easy to build custom shells (i.e. for a gem or application) and complex shells (i.e. for the web). Works on ruby 1.8.7 and greater.

This ripl plugin allows you to evaluate multiple lines of Ruby code.

Lightning is a commandline framework that lets users wrap commands with shell functions that are able to refer to any filesystem path by its basename. To achieve this, a group of paths to be translated are defined with shell globs. These shell globs, known as a lightning _bolt_, are then applied to commands to produce functions. In addition to translating basenames to full paths, lightning _functions_ can autocomplete these basenames, resolve conflicts if they have the same name, leave any non-basename arguments untouched, and autocomplete directories above and below a basename. To make bolts shareable between users and functions easier to create, lightning has _generators_. A _generator_ generates filesystem-specific globs for a bolt. Lightning comes with some default generators. Users can make their own generators with generator plugins placed under ~/.lightning/generators/.
