Our latest addition to our list of UML tools for Ruby is Umlify an open-source project that generates UML class diagrams from your ruby source code.  Umlify uses yUML (probably the most used UML textual tool ) to render the diagram

This is not an easy task since as the author comments : Ruby’s extreme decoupling and duck-typing philosophy doesn’t judge a class by its hierarchy. Thus, variables don’t have a predefined type, which conflicts with uml’s static typed object-model. The objective of this project isn’t to bend uml’s model to make it semantically comply with duck typing (by the use of interfaces, or other tricks), but to add a basic visual representation of the code of your project for documenting and helping maintainers.

If you are a Ruby developer, give it a try and let us know what you think of the tool!
