The team at Reductive Labs recently announced the release of version 0.25.2 of Puppet, the open source Ruby-based configuration management and automation tool for Linux and Unix servers. In this software bug-fix release, 123 open tickets were closed, and the developers claim a reduced memory footprint, improved error reporting, threading, and lock contention (a source of reported system hangs).
LESS and Sass are Ruby tools that allow to reduce redundancy in CSS files by introducing variables, mixins, and other time proven language features into CSS. We take a look at how the two tools work and what they offer.
Martin Fowler talks about ThoughtWorks's experience with using Ruby on client projects for the past three years, and the creation of a Ruby-based product 'Mingle'.
In this article, Jean-Jacques Dubray questions the belief that code and models are two separate worlds. He presents a unified view of Model Driven Engineering, Architecture and Programming models based on a novel approach to specify execution element semantics in DSLs.
In this talk Glenn Vanderburg discusses what the Ruby community has learned about building DSLs, and shows how to build state-of-the-art DSLs without going overboard.
After many years in development, Intentional Software has finally released their Intentional Domain Workbench (IDW). JetBrains has open sourced their Meta Programming System (MPS), currently in Beta 2.
In this article Vaughn Vernon explains the difference between internal and external DSLs and shows the steps involved in developing a complex external DSL.
MountainWest RubyConf took place from 13-14 March in Salt Lake City. All talks are available from Confreaks; we picked some interesting ones – Rails 3 and Merb, DSL design, usability on Rails, Vertebra – and give a coarse summary and some pointers into the talks.
In this presentation recoded during QCon London 2008, Magnus Christerson discusses about the importance of using DSLs which allow business experts to freely express their knowledge about their domain using familiar tools. Henk Kolk presents a concrete example addressing pension fund issues and based on a DSL.
This article introduces RGen, a modeling framework inspired by openArchitectureWare and technologies like the Eclipse's EMF. RGen uses internal DSLs for defining metamodels and offers a full modeling stack for Ruby.
Meta Programming System (MPS), a new Language Oriented Programming tool from JetBrains, allows the developers to extend programming languages as well as create Domain Specific Languages (DSLs) for enterprise applications. JetBrains development team recently announced the release of beta version of MPS software.
As key part the Oslo tools is a language for modeling textual DSLs (MGrammar). This article is an an attempt to try and use MGrammar to write a small parser that can interpret dates expressed in natural language.
Given the growing interest in Domain Specific Languages, Michael Feathers provides some reflections on external DSLs, their advantages and pitfalls as well as possible success and failure factors that he believes to be function of far more than the technology.
Based on their vision to deliver on the promise of model-driven development in SOA where business users, SOA architects and developers will be able to use the modeling tools to collaborate on composite applications, Microsoft has recently made several announcements about its modeling strategy.
JVM-compatible languages such as Scala, Groovy and JRuby are recently gaining more popularity for developing Domain Specific Languages (DSLs). But are they better suited to creating internal DSLs than the Java programming language? Venkat Subramaniam explains why "Essence over ceremony" and "Metaprogramming" features in a dynamic language like Groovy help in developing internal DSLs.
