RGen: Ruby Modelling and Code Generation Framework by Martin Thiede

The Ruby based RGen framework provides support for dealing with models and metamodels, for defining model transformations and for generating textual output. It is tightly coupled with the Ruby language as it uses internal DSLs. Following the Ruby design principles, it is lightweight and flexible and supports efficient development by providing means to write concise, maintainable code

Developing a Complex External DSL by Vaughn Vernon

I have provided a high-level overview of what DSLs are in general and a bit more specifically what internal and external DSLs are. I also cover the main challenges and patterns involved in developing a complex external DSL. This provides a brief but firm foundation for doing meaningful DSL development.

The public beta of Twitter OAuth support has been released and I’m excited to introduce a new library that I’ve been working on called TwitterAuth. TwitterAuth is a Rails plugin that provides a full external authentication stack for Rails applications utilizing Twitter.
