A high-level programming enviroment (Ruby) for vector graphics.

XRVG stands for "eXtended Ruby Vector Graphics". The purpose of this project is to define and implement a high-level and powerful programming environment for vector graphics generation.

an algorithmic vector library for ruby with idiosyncratic design principles (unit free?) and a recursive bent.

Sometimes you want a single object to behave differently depending on what state it’s in. For instance, a traffic light has a different color depending on whether it is informing people that they should stop, slow down, or proceed. Or a user account object might behave differently depending on whether the account is in the “confirmed” state. AlterEgo can help you set up these state-based object “personalities”. AlterEgo will help you to define a set of valid states for your objects, and to define the allowable transitions between states. The real strength of AlterEgo, however, is in defining separate behaviors for each state that the object is in. Underneath the covers, AlterEgo will arrange for your object to delegate to a different state object depending on what state it is in. You can either explicitly define these state objects as classes, or use a concise DSL provided by AlterEgo.

A state machine plugin which allows each state to have different methods and behaviours.

AlterEgo is a Ruby implementation of the State pattern as described by the Gang of Four. It differs from other Ruby state machine libraries in that it focuses on providing polymorphic behavior based on object state.

In effect, it makes it easy to give an object different “personalities” depending on the state it is in.

save

provides a really easy way to write tasks that must be done repeatedly or at a certain time in a simple Ruby DSL. It can even write out crontab files for you based on the commands and times that you give it.

Hirb::View.formatter_config

Irb is a great place for interacting with Ruby. Unfortunately, even with the colorful help of wirble, it's not so great for visualizing the output of those interactions. Hirb aims to change that.
