For the past month or two I’ve been working on [mobl](http://github.com/zefhemel/mobl), a [DSL for the mobile domain](https://zef.me/2693/lets-build-a-dsl). It is the first larger DSL to be developed completely using [Spoofax/IMP](http://strategoxt.org/Spoofax/) (site is down at the moment, due to a power outage at the TU Delft). Spoofax is our new tool for developing domain-specific languages complete with Eclipse plug-ins. It’s based on [SDF](http://meta.cwi-incubator.nl/Meta-Environment/SDF) and [Stratego](http://strategoxt.org) and the Eclipse and Java integration makes it a much more user-friendly and nicer experience, both for the language’s users and their developers.
Recently, [Eelco Visser](http://blog.eelcovisser.net/) (my “boss”) gave a talk at the IFIP WG 2.11 meeting in St Andrews about Spoofax. He just [posted a video of his talk](http://blog.eelcovisser.net/index.php?/archives/128-Spoofax-The-Language-Workbench.html) in which he demonstrates a simplified version of WebDSL (called NWL) and its implementation. May be interesting to those who prefer watching a video over reading a manual or paper.
